Description


Description:

Strong anti-interference ability. The module uses the driving scheme of CPLD + SDRAM, which far more superior than SSD1963 and RA8875. Solve the problem of bad immunity, death and white screen from SSD1963.

Good simplicity. Not need an initializer, what have to do is reset can start work. You can use 5 register command to control it. Greatly simplifies the program code, reduce degree of difficulty of debugging the program and error probability.

Fast speed. The respond speed of W/R cycle can be up to 200ns. The fastest full screen refresh rate is 13 frames. 8M SDRAM correspond to 8 pages display cache. The display registers and RW one is set independently. Display page and RW page also can be in which data can be written in the background. Just using one command to change screenful display data instantly. Far more superior than RA8875.

Good display effect. TFT drive timing and circuit design have been optimized to ensure accurate color reduction, display a stable, eliminate flicker or channeling color and offers LED backlight driver, you can adjust the brightness from 0 (off) to 16 (fully open).
