oled character display

Now many users prefer assembled computers according to their needs, and in the choice of a single configuration , when assembled , is not clear LED display is good, or LCD good . Today, we do a detailed analysis.

LED Display:

1 LED display currently on the market called , in fact, "LED -backlit LCD display ." Do not see the LED display on the monitor mistaken for next-generation technologies , in fact, the latest technology is called OLED, it is still just an LCD monitor. Now popular TFT LCD Module  are CCFL backlit LCD display.

2.LED display, which is a light-emitting diode arrangement consisting of a display , low voltage scan driver with low power consumption, long life, low cost , high brightness, less failure , viewing angle and viewing distance , etc. .

3 In today's environmental philosophy has been that some environmentalists and environmental brand began to Graphic LCD Module emphasize the "mercury " concept LED panel , mercury-free LED panel energy saving, LED power consumption is only 60% of the ordinary .

Tsingtek oled module than the crystal layer

1. LED or LCD than the crystal layer , OLED organic plastic layer is thinner , lighter and more rich in flexibility.
2.OLED relatively light emitting layer , so the flexibility of its primary rich material may be used , without the use of rigid material. OLED grassroots plastic material, while the LED and lcd modules  glass substrate used .
3.OLED brighter than the LED. The organic layer than the OLED corresponding to the LED thin many inorganic crystals , and thus the conductive layer of the OLED and the emission layer may be a multilayer structure. In addition , LED and LCD glass as the support needed , and the glass will absorb some of the light. OLED is no need to use glass.
4.OLED do not need to use the LCD backlighting system ( please refer to LCD ( liquid crystal display ) works ) . Graphic LCD Display  will selectively block certain backlighting work area , so that the images appear, and it is by self-luminous OLED . Because OLED without backlighting system , their power consumption is smaller than LCD (LCD power consumption of the backlight system for most ) . This is for the battery-powered device ( e.g., a mobile phone ) is particularly important .

5.OLED easier to manufacture , can be made into larger size. OLED is a plastic material , thus making it larger than the area can be flaky . And you want to use so much pave crystals and put them , they have much more difficult .

Tsingtek oled display module screen using a light source

LED display and LCD display is actually its the same, are the LCD is also no difference. The main difference is that makes the screen backlight to produce different light sources .
Ordinary LCD CCFL light source is used , that is, the cold cathode fluorescent tube ( look similar to the copy in the scanning lamp ) , one each side of the screen , on the back of the display has a backlight , the fluorescent material composition, You can make light OLED Display evenly distributed on both sides of the entire back of the screen , so that the whole screen evenly lit. However, because of technical limitations , such as the display brightness is not completely uniform , but it is difficult to find , but also a certain lamp life , a long time will be yellow .
LED LCD screen using a Lcd display modules source , which is the light-emitting diode ( just like on the red blue lights as appliances ) . Such very low power light emitting diodes , lamps and because it is not composed of one array can be uniformly distributed in the back of the LCD screen . Good brightness , the backlight more evenly. Such displays can be thinner and more energy to do , LED life span longer than the life of CCFL , hair color stability is not easy to yellow.
Remember the two display screens are used as there is no difference. But just different light backlight

Tsingtek oled graphic display Display content can be replaced at any time Tsingtek oled module

LED display (LEDdisplay, LED Screen): also known as electronic display screen or floating word . By LED Dot Matrix and led pc panel composed by red, blue, green blinking LED lights to display text , images , animations , video, content can be replaced at any time , all components are part of the modular structure of the display device . Traditional TFT LCD Display usually consists of a display module , control systems and power systems. LED lights display module consists of the lattice structure, responsible for the light-emitting display ; control system by controlling the corresponding region of the light off , the screen can display text, pictures, video and other content, color, color screen is mainly used to broadcast text , all the main color is playing the animation ; supply system is responsible for the display of the input voltage and current into a voltage and current needs .
2, the liquid crystal display (LCD) display for a type of digital type watches and many portable computers. LCD displays use two sheets of polarizing material with a liquid crystal between Character LCD Module them is added. When current flows through the liquid causes the crystals to rearrange , so light can not through them . Therefore, each crystal like blinds , both allow light to pass through and can block the light. Liquid crystal display (LCD) technology information products are currently moving light, thin, short, small development goals , with a long history in the computer peripheral products in the display is certainly no exception. Under easy to carry and transport for the former title , such as traditional CRT display CRT monitors and LED display boards, etc. , are subject to too large or very huge power consumption and other factors , could not reach the actual needs of the user. And the development of LCD technology just to meet the current trend of information products , whether it is at right angles to the display , low power consumption , small size, excellent radiation or zero

Tsingtek oled module which is particularly important, and simplify the design process.

For example, the 2.7 -inch display requires 80mA current to render all-white images, but only 5mA current display other icons or graphics. Therefore , OLED power supply required to achieve high conversion efficiency for all load currents . In order to achieve such OLEDModule efficiency , energy saving mode requires the use of advanced technology to reduce the load current to reduce the converter switching frequency. Since this is a voltage controlled oscillator through (VCO) is completed , it can be possible to minimize EMI problems , and can control the minimum switching Graphic LCD Module frequency outside the normal range of 40kHz audio , which may prevent the ceramic capacitor noise input or output . When using such devices in mobile phone applications, which is particularly important, and simplify the design process.
By emission characteristics for maximum power consumption is not white , is the brightness value to determine power consumption . Such as red , blue, green, white luminance value is generated when the light intensity values ​​30 10 together . So the red , green and blue values ​​into a white value ( theoretical value ) 3.3 synthesized a 10. LED or OLED speaking from the human eye to see the same brightness , blue CFL .

Tsingtek Serial Lcd Display oled module

With red, green and blue LED as backlight to achieve segmetn color LCD display method

Let us talk about dot-matrix color LCD display method :
Common color dot-matrix Tsingtek Serial Lcd Display Module is , the principle is that each pixel is composed of red , green, and blue dots , the pixel is small ,
That the human eye can not distinguish between these three points consisting of pixels in space , the feeling is a point. Pixel color impression
This is the color of the superposition of three points , respectively, the control points of the three colors , the color of the pixel can be controlled .
In short, the basic principle of a dot-matrix LCD is a color space in close proximity to the use of different colors to achieve superposition .

Segment LCD display color pen How ?
We know that the pen strokes graphic lcd display module segment display are relatively large, did not take advantage of the close proximity in space like a dot-matrix color LCD
Superimposed to show color . So how to display color it? Can not be superimposed on the space , we can be superimposed on the use of time . For example, there
A red and green LED, the cycle of alternating red and green lights . When alternating slow, the human eye can see the color red LED for a while ,
One will be green , alternating . When alternating fast (eg alternating 60 times per second ) , who saw the brightness is a constant yellow.

Pen -segment LCD itself will not change the color , but you can block the light . Using red, green and blue LED backlight low temperature lcd display do segmetn rapid cycling
Alternating light red, green , and blue , the human eyes perceive is a white backlight . If you want a lcd graphic display modules  segment display red pen , then the backlight
When displayed alternately to blue, so that sum segment display ( ie, blocking light through ) , backlit display to green , but also to prevent the light through the sum segment . Only when
Backlit display to red , just shut sum segment that let light through . Thus , the extra segment where it succeeded in preventing the blue and green light so that only the red
Through color backlight , which sum segment on the show red. Blue and green and so on, can also be used to display more of red, green , and blue overlay
Colors, such as strokes , respectively, so that the red, green, and blue colors are passed, it shows a white color lcd display module .

If the control section of the light pen is only the opening and closing of two states , no other intermediate half-open state,
You can display 8 colors : red, green, blue , cyan, yellow, purple , black, white .

If you adjust the strokes of each color of light through time ( for example, when only a part-time translucent transparent ) , you can do more colors , but no
Necessary . Because this is segmetn LCD, not a dot-matrix LCD, generally do not require excessive gentle colors , naturally not need to show much color, 8 colors enough.

LCD driver static and dynamic drive in two ways, in the absence of a dedicated IC cases, the use of static drive to achieve segmetn color LCD display is relatively simple .
Static drive requires a lot of pins, so the display can be used when little strokes

Ordinary LCD monitors 16x1 Character LCD Modules

The difference between the classification and ordinary LCD monitors display

Industrial LCD monitor features a TV in a simple , no TV function and acceptable than other attachments , but in terms of performance , but far more traditional TV and demanding, the main difference is reflected in the following aspects . High resolution Tsingtek 16x1 lcd display screen , as is a conventional television stations received RF signal emitted , the signal corresponding to the video image is usually less than 16x2 lcd, thus generally 400TVL television vertical resolution . Closed-circuit security surveillance and industrial uses from consideration , must request LCD monitor with high image clarity , color reproduction screen TV 's color is quite beautiful , with the development of television , and now there are many TV With standard , cool colors , warm colors , and many options are one purpose, which is to make the picture colorful, but unrealistic . Monitoring is different, the control room from the perspective of security in accordance with the application , the screen must pursue the truest , most original picture. If there is a radiation characteristic clarity main video channel decision, but also the principle of liquid crystal detector mainly by red, green , and blue color signal and the corresponding position in the luminance signal of the decision . Because usually dynamic images , video playback screen 16x4 lcd display monitor when the observed static extraction, color reproduction of an LCD monitor is much higher than the requirements of the TV , the stability of the machine, as a set of closed-circuit monitoring of the output section , LCD monitor must work 24 hours continuously without interruption while the TV is powered using the daily working hours to do more than a dozen hours , in addition, general industrial use or the use of closed-circuit monitoring may be more harsh environment , which is required of the LCD monitor reliability and stability , and the TV comparison, in the design, current, power, temperature and resistance to electrical interference LCD monitor , click the shocks and the average time between failures are much larger than the TV , while You must also use the LCD monitor fully shielded metal housing to ensure electromagnetic compatibility and interference performance ; in the selection of components , various characteristics of the element voltage, current, temperature , humidity and other LCD monitors are higher than the point the actual use of the components ; while in the installation, commissioning , especially the original and the whole aging requires high temperature, high on the aging pipeline is energized closed environment of aging for more than 24 hours to ensure the stability of the whole machine. The above analysis shows that there is , if you use the TV as a monitor terminal LCD monitor , in addition to the more blurred image may feel less clarity , color reproduction is poor , the point is not suitable for practical use components without interruption of continuous use requirements. If forced to use the TV as a 20x2 lcd display monitor. Ranging prone to failure, severe cases may be due to the TV's operating temperature is too high and cause an accident , professional security monitoring, recommended choice for professional LCD monitor , rather than televisions, monitors instead. After all, the LCD monitor representing very small part of the whole monitoring costs , little money and can not be mistaken for the provincial event .

Consistency of principle, all objects on the screen protection , such as windows, buttons , menus, etc. According consistent style . The size of the button at all levels , bump effect and mark the font, font size remains consistent , the background color of the button and the interface consistent . The concept selection interface depends on multiple interfaces . The interface can be designed for cycling , running , if a large number of interfaces , you must design a rational open architecture interface . Choose simple and permanent structures while the operator to quickly understand how and open interfaces. A processing amount of information the user is limited , the accumulation of large amounts of information on the screen may affect the interface between friends . In order to provide a sufficient amount of information while ensuring the interface is simple , the design uses a set of hierarchical spatial arrangement . Classification refers to the space by function into multiple groups, each group of multiple levels of refinement according to its logic. Level button button control with two buttons pop up and hide the key to ensure a clean interface. Different hierarchical levels of the button is longitudinally expanded in different regions , a clear interface between the regions . Using a button in the pop-up button while the lower button on the other to achieve the same level of concealment, is a logical relationship more clearly.

High-temperature polysilicon technology Character LCD Modules

Tsingtek Low temperature lcd display polysilicon technology and high-temperature polysilicon is a corresponding (High Temperature Poly-Silicon, referred HTPS) concept we have previously mentioned , the use of high-temperature polysilicon quartz glass as the substrate low temperature lcd display , and the high purity quartz glass are very expensive, and very difficult to achieve a larger size , which determines the temperature polysilicon technology can not as a display of the computer. However, large-screen HDTV lcd graphic display modules Projection TV (Large-screen projection TV) in areas such as high-temperature polysilicon technology found in commercial / home front projector (Front projectors), his own position , especially in the three-piece LCD projection system, high temperature polysilicon technology in the field of global market share as high as 55 %.

Low-temperature polysilicon Character LCD Modules rising star

As early as 1999, the low-temperature polysilicon Tsingtek low temperature lcd display has been around , so it is far from what the new technology . However, due to various reasons, the slow development of low-temperature polysilicon technology , and even stay long in words, until the recent breakthrough in the field appears to be outside again before starting to pay attention . Low-temperature polysilicon stands for "Low Temperature Poly-Silicon (LTPS, polysilicon is also known as the p-Si, the same below ) ," which is a branch of polysilicon technology. On the lcd graphic display modules monitor , the adoption of polysilicon liquid crystal material has many advantages , such as thin-film circuits can be made thinner and smaller , lower power consumption and so on , we will focus on the following . However, in the early development of polysilicon technology , in order to transition from the amorphous glass substrate structure (a-Si) is a polycrystalline structure, it must use a laser annealing (Laser Anneal) high-temperature oxidation step , when the temperature exceeds the glass substrate graphic lcd display module . Known, ordinary glass softens at this high temperature melting , can not work properly , and only the silica glass to be able to withstand such high temperature processing . The quartz glass is not only expensive and sizes are smaller , not as a display panel makers naturally chose the cheap amorphous material (a-Si), which is the situation we see today. However, the industry has not given up efforts to develop low-temperature polysilicon technology become the consensus , after years of effort, low-temperature polysilicon finally step into reality. Compared with the conventional high temperature polysilicon , low temperature polysilicon although laser irradiation step needs , but it is used as a heat source is an excimer laser , the laser transmission through the system will produce a uniform distribution of the laser beam energy in the amorphous structure and projected on a glass substrate when the glass substrate is an amorphous silicon structure of the energy absorption of the excimer laser , the structure will be transformed into polycrystalline silicon . Since the entire process is completed in less 500-600 ° C , conventional glass substrate can withstand , which greatly reduces the manufacturing cost , the polysilicon LCD technology into the display area also feasible .

Character LCD Modules defect and technology breakthrough

Due to limitations inherent principle , LCD display quality in terms of color CRT is still difficult with the same par . We know that Tsingtek the graphic lcd display module  panel itself is unable to achieve self- luminous, but it can play a role in blocking the light , in order to achieve a complete display, a backlight assembly must be designed for it (Backlight) - backlight emits light, after the reflection plate , light guide plate , an optical diffusion sheet , a prism sheet and other auxiliary member is irradiated to the liquid crystal panel , a liquid crystal panel of the electrical drive signal at a precise determined luminous -off of each pixel region , and the color filter role in the formation under different shading , different colors of light output - in the user point of view, is shown on the LCD screen, the established color screen. Such works exist many drawbacks : First , relying on the filter in order to achieve color output , and because the driver IC restrictions , early color lcd display module for each channel can be achieved only 6bit color combinations , RGB three color channels add up to 18 display can show only the total number of 262,144 kinds of colors , which is 24-bit true color has a long distance. Because not show enough color , graphic lcd display module is difficult to achieve a satisfactory level ; secondly , LCD backlight to be able to help the formation of light output , and quality characteristics of the backlight of the Serial Lcd Display Module quality , use of life expectancy and other indicators have a significant impact . Widely popular backlight type CCFL cold cathode fluorescent lamp, it has a low cost , mature technology , etc., both the performance and stability are proven , but the cold cathode fluorescent tube light sources are light emitted want to spread evenly each region of the panel requires relatively complex support assembly more difficult to control the thickness of the screen . And CCFL backlit color display in terms of mediocre , life is also more general ; once again , the energy efficiency of the backlight low. In the light from the backlight to transfer the screen , the light energy loss is very serious , and ultimately only about 6% of energy use may be true , the energy efficiency is quite low. In order to achieve higher brightness and contrast , manufacturers must increase the output power of the light source lamp or increasing the number of adverse consequences is the machine power up. This has much influence on the desktop LCD monitor or LCD TV will not, but a great influence on the laptop LCD screen . LCD is the highest -power laptop components , in order to maximize battery life , the industry actively develop low-power LCD screen , while the energy efficiency of the backlight is clearly contrary thereto .

Character LCD Modules liquid crystal display technology analysis of recent progress

In just a few years time , LCD rapidly replacing CRT, become occupy the mainstream display technology. The prices are civilians , while the Tsingtek color lcd display module quality is also getting better and better . Initially, the viewing angle is small, long response time graphic lcd display module is considered the most serious flaw in the joint efforts of the major panel makers , have successfully developed a new generation of Serial Lcd Display Module panels , and quickly mass production in a very short time. Achieve universal access to a new generation of panel viewing angle of 160 degrees or more , and some more excellent technology can achieve 170 -degree viewing angle , so almost the same level as CRT , LCD narrow perspective of a certain defect changed . Secondly , the new panels generally have less than 16 ms response time , many products even down to the level of 8 ms , and only when the response time exceeds 25 milliseconds , the human eye can clearly feel the image delay , a new generation of 3D LCD fully meet game application requirements. And to solve these two problems for the popularity of low temperature lcd display and lay a shot in the arm , coupled with increasingly lower cost , only 15 inches LCD monitor specifications realized price of civilians , even the 17-inch products fall into the 2,000 yuan , the mainstream replace CRT is a natural thing , and this is what we see today in the market situation . Although perspective and response time has been greatly improved , the quality of the LCD display to get some improvement , but the pace of the LCD has not stalled , the industry 's technological improvements will focus on the following areas: improved image contrast , allow it to be exhibit a richer sense of hierarchy ; further improve the color performance of the LCD , so that it can be close to or even reach the level of the CRT ; continue to reduce the power consumption of the display , to enable more energy efficient and meet the needs of mobile applications ; the life of existing as the basis to further improve ; expand into new application areas, reform the manufacturing process , improve yields and achieve further reduce manufacturing costs.

They do this with mass production in August, September, flat panel and assembled in October through graphic LCD, to prepare for November and December market. So consumers will see many new products in the next marketing season , when choosing gifts for family and myself have more choices.

 Apple's new iPad Air 9.7 inch panels from small shipments began in August , September, October substantial growth while continuing to increase. However , due to the iPad Air panel yield less than iPad 4, while labor shortages in mainland China after the National Day , so the iPad Air panel shipments in September is still less than the iPad 4. In addition, part of the 7.9 -inch mono LCD display 2 panel , to the end of September , only South Korean panel makers will be 7.9 '' retina panel on the market, but shipments of less than 100 million units in September , October is expected to be increased . Because yield issues remain unresolved , the Japanese panel makers still can not successfully be 7.9 inches retina panel volume production.

  Thus , Apple is likely to make another Korean panel makers have begun to supply. Although this situation is not expected to happen this year , that the Japanese panel makers should be smoothly 7.9 "iPad Mini 2 retina panel into volume production in the fourth quarter .

  Whitebox tablet PC panel shipments continue to rise , mainly because of the panel and system manufacturers to provide low-cost chip prompted a large number of mature local dealer to buy a lot for the end of the sales season and prepare for the Chinese New Year . These low-cost tablet computer often as a gift , or corporate incentives and so on.

MOS transistor switching circuit design knowledge oled module

1, MOS tube type and structure
FET is the MOSFET (the other one is JFET), may be manufactured or enhanced depletion type , P -channel or N-channel type of four kinds , but the practical application of only N -channel enhancement type MOS tubes and P -channel enhancement type MOS transistor , it is usually referred to NMOS, PMOS , or refers to two .

For both enhanced MOS, more commonly used is NMOS. The reason is that the on-resistance is small, and easy to manufacture . Therefore, the switching power supply and motor drive applications, typically using NMOS. The following presentation, also mostly NMOS based.
Parasitic capacitance exists between the three pins MOS transistor , which is not what we need, but because of the manufacturing process limitations arising . Parasitic capacitance makes the design or selection of the drive circuit will take some time , but there is no way to avoid back again in detail.
MOS tube can be seen on the schematic , there is a parasitic diode between the drain and the source . This is called the body diode , drive inductive loads ( such as motors ) ,Tsingtek lcd graphic display this diode is very important. Incidentally , only the body diode of the MOS transistor in the presence of a single , integrated circuit chip is usually not .
2, MOS conduction characteristics
A conduction switch means is equivalent to a closed switch .
The characteristics of NMOS , Vgs greater than a certain value becomes conductive , suitable for the case when the source is grounded ( low side driver ) , as long as the gate voltage reaches 10V 4V or on it.
Characteristics of the PMOS , Vgs less than a certain value is turned on, the situation is extremely suitable for the source when connected to VCC ( high drive ) . However, while the PMOS can be conveniently used as high-side driver , but the on- resistance is large , expensive, and less replacement types reasons, the high-side driver , it is usually used NMOS.
3, MOS switch losses
Regardless of the NMOS or PMOS, both the on-resistance conduction exists, so current will dissipate energy in this resistor, which is called the partial consumption of energy conduction losses . Choose a small on-resistance MOS tube reduces conduction losses. Now a small on-resistance power MOS usually around tens of milliohms , there are a few milliohms .
MOS is turned on and when the cut-off , certainly not instantaneous. There is a voltage drop across the MOS process , there is a current flowing in the process of rising , at this time, the loss of MOS tube is the product of voltage and current , called switching losses. Switching losses are usually much larger than the conduction losses and switching frequency , the faster , the greater the loss .
Conducting product of the instantaneous voltage and current is large, will cause great damage . Shorten the switching time ,Tsingtek Character OLED Display conduction loss can be reduced every time ; reduce the switching frequency , the switching frequency can be reduced per unit of time . Both approaches can reduce the switching losses.
