LCD-EX is a 16/24-bit RGB parallel conversion module designed for TFT-LCD displays to be used on RIoTboard and SAMA5D3 Xplained board. The module integrates a TSC2046 chip to implement touch function and a 3.3V regulation chip to realize IIC control and PWM backlight control. LCD-EX can provide 16-bit and 24-bit driving modes for LCD displays and is compatible with SPI 4-wire resistive touch screens.
The following figure is a block diagram that illustrates how LCD-EX works when using 16-bit logic interface.
