The advantage of our TFT LCD module

Nowadays TFT displays is widely using in many field, we have developed a series of TFT display module integrated with controller, aiming at the customers who is using the mono LCD before, and would like to change to using a TFT module in similar way. The advantage of our TFT serial display modules are as following:
。Built-in Frame Buffer
。Dynamic Backlight Control via PWM Signal
。Built-in Clock Generator
。Programmable Contrast and Color Saturation Control
。Embedded 4-wire Resistive Touch Panel Control

the Serial display modules and Character LCD Modules

In 16.0 inches models, X61SL unique fashion and frivolous charm. Dark gray X61SL body design with appropriate curvature, overall looks very harmonious. In 16.0 inches models, X61SL only 2.85 kg weight (with 6-cell battery), which makes X61SL mobility is excellent. ASUS X61SL whole new generation of "Infusion" manufacturing process, the body surface feel smooth, in effect around the cloud patterns, X61SL unique kind of elegance and calm heritage. "Infusion" technology unique Character LCD Modules liquid erosion and corrosion resistance to scratches but also to be able to maintain long-term X61SL look as good as new.16.0 inches 16: 9 Full HD screen to watch the miracle of bringing

When the cinema we have this experience, movie theater screen is very wide, so the presentation of the visual impact is very strong. When we play a DVD with a normal 16:10 ratio screen has a black side down. 16.0 inches X61SL with a 16: 9 widescreen design, when playing Serial display modules high-definition video can be completely removed from the black side, the user's viewing area significantly expanded, really enjoy HD boundless realm. Meanwhile, due to the expansion of visual range, users usually as a list when you open Excel, you can see a more spacious, complete work page, the operation more convenient. In addition, the use of 16: X61SL resolution of 9 screens reached 1366x768, the display screen with the characteristics of high brightness, high contrast and high color saturation.

showing the stability of the lcd module displays the power supply design

control commands via the interface is input to the control command decoder decodes the command, and then outputs the clock, horizontal sync, vertical sync signal, thereby controlling the oscillation frequency of the OLED display, the ranks of the display device, and a COG LCD Display voltage conversion module OLED display contents offset drive module; if the display data (128 × 64bits), then the display data to the control circuit via GDDRAM MCU interface input buffer, then the local color decoder decodes the data, and finally displays the decoded data through the line driver to drive lcd module displays showing the stability of the Serial display modules the power supply design
Hardware architecture design diagram shown in Figure 2, the external hardware circuit DC-DC converter uses TPS7333 chip 3.3V to 5V power into power, and the power signal output voltage and current through the entire SSD1303 controller voltage and current. The entire system needs 3.3V and 12V power supply, MCU (paper, C8051F023) requires a supply voltage of 3.3V, OLED requires 3.3V logic supply voltage and a driving power supply 9 ~ 12V, the voltage of the driving power from an external power converter circuits.

lcd module displays is a block diagram of a logic circuit interface module

display module display is 128, 64 lines, 64 lines using a line driver outputs and two columns of the drive controller, where each piece of column driver 64 outputs. Line driver and the Graphic lcd modules does not matter, as long as the power can be generated to provide the drive signal and the synchronous signal, the external signal module only on the column drivers. Column driver built display memory, RAM is divided into 8, page 8 lines; each pixel on the display state of the display data memory correspondence you display data memory directly as a graphical display of the drive signal , "1" shows "0" is not displayed. Figure 1 is a block diagram of a logic circuit interface module.Instruction modules and LCD driver Serial display modules compatible controller, a total of seven instructions. Not described in detail here, as listed in Table 2 only instruction list. Among them, the state is set to show the first two instructions, the rest of the class to read and write commands.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 access method is a module interface as a memory or I / O devices directly 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.
