9 Inch Custom Touch Screen Lcd Module

9 Inch Touch Screen Lcd Module

Pin Assignment

I: input,0: output, P: Power Note 1: DE/SYNC mode select. Normally pull high.

When select DE mode, MODE=”1”, VS and HS must pull high.

When select SYNC mode, MODE= ”0”, DE must be grounded.

Noto 2: Whon input 18 bits RGB data, the two low bits of R,G and B data must be grounded.

Note 3: Data shall bo latched at the falling|edge of DCLK.

Note 4: Selection of scanning mode

Note 5: Dofinition of scanning direction. Refor to the figure as bolow:

Note 6: Global reset pin. Active low to enter reset state. Suggest to connect with an RC reset circuit for stability. Normally pull high.

Note 7: Dithering function enable control, normally pull high.

When DITHB=”1”,Disable internal dithering function,

When DITHB=”0”,Enable internal dithering function,

Note 8: Reserve for LED power input.
