subject: The Interface Of The Psp's Tft - Lcd Module To An Fpga [print this page] In the previous article, the first part of an investigation into the use of TFT - LCD Module start, (Sharp LQ043T3DX02) as the Sony PSP game console to use the display screen of the hand, as a hobby and homemade items are displayed. Article in particular looking at the mechanical and electrical interface module. In this article, I will look at the TFT - LCD module's data interface, and how the interface signal is sent to create an image.
Data interface
Signal, to make up the data interface provides data of Table 4 and Table 1, a concentrated form of repeated below. How to 24-bit RGB and 32-bit RGBA display computer-generated image details can be found in a lot of good computer graphics text books (Foley and Van Dam, and Hearn, apple, etc.).
The timing characteristics
The TFT - LCD module timing feature provides all the necessary information to successfully display the image on the screen. This information and data in Table 7 are repeated in Figure 1. I explained further divided into a number of part-time use this feature sheet.
the following i will introduce the advantages of tft lcd module:
It is driven by any normal MCU.
Freeing the user from considering the specific TFT LCD drive issue,
Simple serial ports minimize the system control lines to only 3,
Freeing the user from considering the specific LCD display driver issue, such as tft lcd driver or lcd driver IC.
Unified and simplified command set and hardware interface.
color: 65K.
Support the touch screen and the keyboard;
Support multiple languages. Special character may be satisfied .
Extremely quick image processing speed;
Real industrial-grade design.
Ultra-low power consumption.
This product advantages as follows:
1. Shorten greatly your development time.
2. Lower development cost.
3. We have strong experiences in different fields.
4. Improve your product level greatly.
We have free demo unit for some customers. This unit consists of a 3.5'' UART LCD Module, an MCU module with demo program pre-installed, the source code and its description of the program. So, after you get the demo unit, you will see a finished HMI design and know how smart our product is. Besides, with the example source code, any engineer will know how to make his own HMI design. Meanwhile, please be noted that we are also in a good position to provide technical assistance when the engineer is programming. If you are interested in the demo unit, just let me know. Then I will send it to you against your express account.
