one is the direct access oled display module, the other is indirect access.

Display Module with Cygnal microcontroller hardware interface design
VGS12864E interface connection in two ways: one is the direct access mode, the other is indirect access. Either way, you want to access the module must first read the contents of the status register to determine the "busy" flag can be accessed when not busy. Direct Graphic lcd modules  access method is a module interface as a memory or I / O devices directly  oled display module
 linked to the MCU bus, MCU to access memory or I / O device mode the module operation. Indirect access MCU module is operated via software simulation control timing. Here is indirect access interface design Cygnal C8051F020 MCU and VGS12864E of.
Cygnal C8051F020 is an American company launched a mixed-signal SoC-based 8-bit microcontroller, a highly integrated mixed-signal system-on-chip. It has a 100-pin TQFP package, low power Character LCD Display supply voltage of 2.7 ~ 3.3 V, all I / O, RST, JTAG pins are resistant to 5 V voltage; has high speed pipelined 8051-compatible CIP51 core structure (up to 25 MIPS). The MCU has a total of 64 P0 ~ P7 purpose I / O ports, each port pin can be configured as push-pull output or open-drain output. For VGS12864E, due to its operating voltage is 5 V, and C8051F020 operating voltage is 3.3 V, so the output C8051F020 better able to drive 5 V input OLED, the system requires additional configuration. In addition to the corresponding output port is set to "open drain", but also in the circuit will be connected to each port through a pull-up resistor on a 5 V power supply, so you can ensure C8051F020 logic "1" output can be raised to 5 V. The interface circuit shown in Figure 2.

oled graphic display for a type of digital type watches and many portable computers

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 LED display usually consists of a display module , control systems and power systems. graphic lcd modules 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 them is added. When current flows through the liquid causes the crystals to Graphic LCD Module 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

Character LCD Modules TV money saving four strokes

Not pursue large-size screen

Treatment to cure , if you pay attention to the LCD TV 's performance in energy efficiency , it should at the beginning of the purchase to buy a more energy-efficient , low -power products, and in addition to the application of energy-saving technology television itself , the TV screen Power consumption is also quite a lot for the size of the impact . We can understand that when using the phone, the phone standby time big screen is generally short . LCD TV is the same reason , the same paragraph TV screen size is larger, the power consumption is also greater. Therefore, we should choose for their own living room to watch TV models , but not unilateral pursuit of " big-screen enjoyment," too big screens either for consumption or for the perception will have damage.

When viewing the volume to moderate

Having impact on the power consumption of the screen , we look at the voice , now mostly use LCD TV built-in speaker design , for the average family is completely enough, but sound also depends on the size of the speaker 's own power , the greater the power the greater it sounds , power consumption also increases, so if we do not necessary, it is best not to open the TV volume too large , just listen to the clear enough , so that you can to achieve the purpose of saving , and secondly, it will not wake the neighbors a break , and you can extend the life of the TV speakers and then to a certain extent .

TV consumes very high brightness

Now we look at the brightness of the TV ,mini lcd module if determined , then we take a look at your own home TV screen brightness settings, this setting may seem simple, but in fact will cause a relatively large impact on the power consumption of the TV , the brightness of the more high power consumption will be. Of course , we do not regard the brightness of the TV so that we pick very dark , but we need reasonable adjustments , in general , the brightness of the LCD TV does not need to be set to 100 %, generally use 50 percent or slightly higher brightness you can, you know 100% brighter than the darkest brightness power consumption to increase more than 50% of the level seen how important the "Brightness" LCD TV for energy-saving effect is .

Standby power consumption is also

Note above finished watching television after saving techniques , and finally watch television after use . I believe there is a part of the habit of watching TV friends when turned off the TV with a remote control after walked away, but in fact we need to know if you do not press the power button, the TV is not real power, but only in standby mode , in this state the TFT Lcd Modules TV will still be a few watts of power consumption exist, though not high , when accumulated in the long run will also be considerable. After watching so we must remember to turn off the TV the TV's power , so as to better energy conservation, electricity saving for our next record monthly expenses.

With you to understand Character LCD Modules large screen project implementation point

A complete set of large-screen LCD splicing system , in addition to the front of the screen , the will to involve computers, networks , video surveillance, integrated wiring and numerous peripherals and many other devices , these features also created a large-screen LCD splicing system installation complex and difficult characteristics. In fact, in addition to these features , large-screen LCD splicing system for engineers not only have excellent engineers and technicians , but also have strong project management and operational capacity , only to have these features in order to respond flexibly to various installation projects .
Typically, large-screen LCD splicing system project can be divided into four distinct phases , namely: project planning, preliminary survey , project implementation and post-project . Among these four stages , pre- survey and implementation of the project is very important, if these two stages in the implementation process problems, will seriously affect the progress of the projects and the quality of the projects . Before the implementation of the project -based investigation and implementation of two parts which need to pay attention to what ?
First, the pre-construction survey points:
Pre-construction survey in addition to the construction site in person to understand the investigation , they also need to conduct a detailed and customer communication , and make the overall construction project planning , as these largely determines the length of the project cycle , cost control, and rendering the final result , it must be particularly careful.
1 First, install the equipment on the ground to be flat.
Because the entire large-screen LCD splicing system weight is very large especially rear stitching, its technology determines its cabinet is very large, and very heavy, so if the floor is ceramic tile installation of equipment , it must first confirm whether it can withstand such weight , preferably fixed on another device antistatic floor on the ground, in order to ensure long-term ground by heavy deformation.
2 , followed by wiring
Large-screen LCD splicing system wiring, power lines and signal lines to be separated in order to avoid unnecessary interference with the signal ; another big screen COG LCD Display splicing according to the specifications , the cabinet position , the signal source location for all kinds of lines calculated cable length , number of joints and the signal line names. But also confirm with the customer , project pipeline channel is available to meet the actual needs, in order to continue follow-up work .
3 , ambient light
Because large-screen LCD splicing products brightness is relatively limited, if the system of ambient light is too bright , the picture effect would have been affected . Under normal circumstances, required within 4 meters in front of the screen is dark , it is best not to install fluorescent tubes can be installed concealed downlights , light to shine directly on the screen can not and must have a separate switch.
In addition to the installation of tube lights and large screen devices in parallel , try to make the work area has adequate lighting , but will not have a significant impact on the screen , the screen may be near the incoming light ( such as windows ) , if necessary, to be blocked while the device is running best to turn off the light ,16x2 lcd in order to ensure normal operation of equipment .
4, the framework requires
Taking into account the convenience of installation and maintenance , the frame must be removable edging edging . Outside the framework of the fight away from the wall along the side ( up and down about four sides ) set aside about 25mm clearance on each side , a large video wall should be increased according to the number of columns margin . In addition , in order to post into the box maintenance, repair channel principle is not less than 1.2m wide. Removable side bar to hold the edge of the screen 3-5mm is appropriate, in the box and the screen is fully in place, and finally fixed removable trim.

Character LCD Modules large screen display wall buy recommendations

LCD LCD large screen display wall proposed purchase of " Three Views" - see "Response time " to see " the number of colors ," and see " viewing angle ."
Response Time
For this indicator , can be considered as the input image signal response speed . Is the same point in the panel above ,OLED Display from black to white and white to black from the time length . If the index is too long , then quickly switch the image or video playback will produce " ghosting " effect, to discourage the use .
Response time determines the number of frames per second, the screen can be displayed , usually when the screen display speed is greater than 25 frames per second , the human eye will quickly change the picture that is continuous screen. In high-speed ball running , high-speed switching or moving picture , to achieve the best display effect , you need the screen display frequency exceeds 60 frames per second , the response time of 16ms or more to meet the requirements, that is, the shorter the response time , rapid changes the picture shows the better.
Number of colors
Number of colors , refers to the monitor can display the number of colors , the higher the index , the picture is more abundant . Early , LCD can display only 16 colors, about sixty-five thousand kinds , while recent period , as technology advances , BSV has an LCD can display about 24 colors, some 1,600 million. If just from the indicators ,Graphic OLED Display LCD is still some distance away from the CRT , but realistically speaking , sixteen million kinds of color has to meet the requirements of most applications .
Viewing Angle
For this early use of laptop users must fully understood , using laptop computer , front screen image is the sharpest , assuming a certain angle tilt angle, you will not see the screen . Up to what point can see the screen images , this angle is the viewing angle. Viewing angle can be divided into horizontal viewing angle and vertical viewing angle . For this shortcoming , LCD liquid crystal mosaic screen manufacturers such as BSV development has also made great efforts , and now the LCD viewing angle can reach 178 degrees .
Also, got to choose the products carefully selected , calm , first select the products with higher brand awareness . As the LCD where the most critical parts LCD panel has been decided BSV splicing LCD screen quality and price and other factors , only those with advanced and reliable backing panel production lines , product quality and after-sales service of course, can be guaranteed.

Produce full-color Character LCD Modules device program adopted

Produce full-color OLED device, you can use the following scenarios:
1. RGB mode superposition device
This mode is not the way to achieve color display light color conversion or color filter, thus increasing the luminous efficiency.Character LCD Modules  This superposition model requires material better performance and better driving characteristics, process conditions demanding.
2. Blue light emitting device + color conversion layer mode
This model was first developed by Japan's Idemitsu success, there is a blue light-emitting organic electroluminescent devices is the highest energy, so let through light color conversion medium blue, green and red excitation. The blue organic electroluminescent device structure of anode / hole injection layer / hole transport layer /
Emitting layer / electron transport layer / cathode, wherein the emitting layer is a blue electroluminescent DSA materials. Luminous efficiency of 61m / W, life of 20,000 hours, on the basis of light-emitting color conversion medium to produce a multicolor pattern organic electroluminescent device. This process requires efficient blue hair
Optical layer.
3. White device + color filter pattern
This technology was first launched in Japan TDK Corporation, the white light emitted by the device to obtain a color filter color. High cost of the color filter, the light emitting efficiency is not high, although this pattern can obtain high color purity, red, green and blue light emitting device trichrome different aging characteristics,color lcd display module the color purity will change over time.
Encapsulated OLED device performance characterization tests must be carried out, mainly brightness - voltage curve and the current density - voltage curve. The steeper the curve rises, the brightness with voltage, current density with the faster voltage rise, the luminous efficiency will be higher.

GMP compliant technology of epoxy self-leveling coatings Character LCD Modules

With modern industrial technology and production development for cleaner production have become increasingly demanding, requiring workshop floor corrosion and wear clean indoor air as a low dust content, such as food, tobacco, electronics, Graphic OLED Display precision instruments instrumentation, pharmaceutical, medical operating rooms, cars and airports and other manufacturing production sites, require clean workshop. This is not only the demand to improve working conditions, more modern product quality assurance. At present many foreign clean workshop floor usually whole polymer surface layer, which is basically a technique called "self-leveling paint" based materials, due to the general case of a chemical substrate for the epoxy coating, so the domestic generally known as "self-leveling epoxy coating" (epoxyself-levellingflooring), which is a weaker material dust analysis. Currently in the country by many manufacturers and users to accept and use, especially in the pharmaceutical industry began in the 1996 National Medical industry implementation of GMP manufacturing standards, including a basic level of hardware production is clean floors.
Epoxy self-leveling epoxy coating is a film-forming material, by adding various additives, pigments, fillers and other processed, has the following characteristics: ① paint self-leveling is good,lcm module  a film in more than 1mm, Construction is simple; ② coating with tough, wear resistant, non-toxic non-combustion characteristics; ③ smooth surface, with good decoration, cleanliness requirements to meet the 100 level.

Connecting technology of liquid crystal TFT Display Module device

Liquid crystal COG LCD Module device by the two glass. The outer lead is attached to the surface of the transparent conductive film made of photolithography, can not use the conventional welding processes. Currently there are connection process:
1, the conductive rubber connector
This is a more traditional way. Conductive rubber strip all known as zebra conductive rubber strip is determined by a layer of conductive rubber, a layer of insulating rubber white laminated into a very thick one, and then in the direction perpendicular to the surface of the rubber strip cut into strips. When used, just outside the lead and the liquid crystal display circuit board traces correspond neatly side, the Zebra caught in the meantime, to fix them. To do this, we must make a pressure box. Pressure frame material shape can be any design, but must ensure that there is a pressing amount to about 0.2mm, the need to ensure that the pressure uniform, not bent.
2, the metal pin connector
Stamping into the metal pins, the first liquid crystal display which plug member fixed to the end of the outer lead, to the user, or when soldered or plugged into the circuit board.
These two methods more used digital type, the outer lead much (line pitch> 1.25mm or more) of the liquid crystal display device.
3, hot film flexible connection
Calculators and digital communications equipment commonly used. Its hot conductive connection with a polyester film, in the intervals of graphite printed on a thermal conductive adhesive strips and insulation. When used, the end of the alignment of the liquid crystal display device of the conductive strips of the outer lead securement, plus potential, pressure, and the other end of the conductive stripe aligned snapping lead terminal board, heat and pressure can. Since it takes a certain pressure and temperature, so users need to configure a dedicated hot press.
4, the anisotropic conductive adhesive connections
The so-called anisotropic conductive adhesive is shown in Figure 1 as a hot film. Interspersed with gold plated film in plastic balls, to be sandwiched between the LCD and PCB heat and pressure, the lead because of the thin film pressure, and connected by a conductive plastic ball, since the lead spacing, so it will not horizontal concatenation. So called anisotropic conductive connection. Also known as TAB connection. This connection can easily connect line spacing device is only 0.1mm. Is the high density and large amount of information necessary for connecting liquid crystal lcd module technology. Because it requires precision alignment and precise pressure, temperature control, you need to set the price of expensive special equipment job.
Connection with TAB method the chip directly on the liquid crystal display device on the glass COG mounting method, the pressure in the chip from the board COB hard wire and the chip mounting pressure in the flexible circuit board COF mounting.

Character LCD Modules in SCM System

The LCD module uses a CCFL backlight, which is a cold cathode fluorescent lamp, high brightness, low power consumption, applicable to large-area displays the desired light, but requires the corresponding inverter. The system uses PYE-L10A inverter, which consists of the typical differential pair oscillation circuit, its output through a capacitor is divided into two, two lamps can be lit simultaneously. It is easy, +5 V input voltage, the output is AC 1300V (7mA) around the frequency 20 ~ 30kHz, with minimal conversion loss and a high output efficiency. Overall dimensions of 43 × 20 × 13.7mm. Usually installed in the MCU control panel, two AC output terminal is connected with the high-voltage leads and LCD. Because CCFL uses high voltage power supply, so when used with care to prevent damage due to high pressure shorting other devices. In addition, the use of lead should also note that the interface should not be too long, do not use cable as its output line. Character LCD Display

Generally, LCD liquid crystal display device is driven by a constant voltage to establish an electric field to achieve. Since the LCD typically requires a negative voltage drive power. Therefore, the drive circuit to generate a negative voltage converter chip. The DC-DC input voltage of 5V, the input current of 60mA, the board has the adjustment potentiometer, the output voltage can be negative -2 ~-22V is adjustable to suit the Graphic LCD Display
