However, the smaller size of the single chip is far from the requirement of the dozens of tube feet needed for TFT LCD screens. Therefore need to adopt other chips as a middle management chip, CPLD chip, no matter from the pin or performance meet the TFT LCD driver, so driven by CPLD chip TFT has practical significance. Main design (research) content: Based on CPLD TFT true color screen drive circuit, the main research contents are as follows; 1. Familiar with Quartus II development environment, skilled in using Verilog or VHDL language to develop CPLD procedures; 2. The working principle and interface line definition of TFT LCD screen are designe
