Abstract
The control of display device is the foundation to realize good human-machine interface. Analog TFT LCD screen meets the requirements of the industrial machine in cheaper price and good display characteristics,so it is widely used in industrial machines. For 17. 8 cm (7 in) analog screen, this paper puts forward the scheme that consists of STM32 and CPLD to achieve LCD control system based on single piece of SRAM as video memory, and analyzed the feasibility of the proposed scheme. The key problem of system design was discussed and parts of the program is given. The scheme saves cost and increases the reaction speed of the man-machine interface. It is of certain practical value. 关键词
