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

Principles and structure of the Character oled character display 20x4

Tsingtek lcd display 20x4 the liquid crystal liquid crystal is a liquid capable of flowing like a fortune crystal material chemical properties of crystals . Alignment of liquid crystal molecules have a certain order, arrangement of liquid crystal molecules will change in the role of outside plant , thus affecting his chemical properties.
    LCD screen is composed of two parallel thin glass plate , the distance between the two glass is very small , is divided into small cells filled the LCD . LCD panel itself does not light , he passed backlight display lcd 20x4 screen LCD screen is lit up . Advantages of graphic lcd 128x64 screen is small, light weight, large area display , image stabilization, no radiation, low power consumption and environmental protection features . Compared with the liquid crystal display, a CRT power consumption of the liquid crystal display only one-third .
    TFT LCD screen, the abbreviation thin film transistor liquid crystal screen is the top material belonging to an active matrix type liquid crystal screen , the back has a special lamp, you can take the initiative to each individual pixel on the screen to control, which is what we said active matrix TFT, his reaction is faster , viewing angle , color saturation. TFT LCD screen by the arrangement has a memory , so it will not restore the status quo ante in the current disappears immediately and effectively improves the ability to play a dynamic picture .

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 .

Serial Character LCD Modules interface layout

Industrial HMI Tsingtek Serial Lcd Display Module layout according to ergonomic requirements should achieve simplicity , balance and style consistency . There are three levels of industrial display interface components. First, an overview of the level of the interface . This layer interface to include information about the different parts of the system shown in the system , and how to make part of the coordination of these systems.
Level two is the process interface. This layer contains detailed information for the specified interface is part of the process and COG LCD Display objects that belong to the process equipment parts. This also shows an alarm level set corresponding to each object .
Level three is a detailed interface. This layer provides the interface information of each device object , such as a controller , the control valve , the control motor, and displays a message status and process values. Typical industrial interface structure is divided into three parts ; title menu section , graphic Low Temperature Display area and button parts. 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.
