Chapter 4 LVDS LCD screen display experiment#

The experimental Vivado project is “lvds_lcd”.

This chapter introduces the color bar display of lvds lcd LCD screen.

Hardware introduction#

ALINX black gold 7-inch LCD screen module (AN7000) uses IVO’s 7-inch TFT LCD screen. The model number of the LCD screen is M070AWAD R0. AN7000 LCD screen module is made of TFT It consists of an LCD screen and a driver board. For specific parameters, please refer to the AN7000 user manual. The actual photos of AN7000 are as follows:
