LCD as a new kind of display, with its power-saving, low radiation, small size, heat dissipation degrees low advantages, and quickly became one of the most popular display. And it can not only show the data in digital type, but also can show Chinese characters and chart type, which can not be achieved in the seven-segment LED digital tube can not be achieved. And the LCD display is a pure digital device equipment with this connection is digital, which can reduce signal loss and interference in the digital-analog conversion process, followed by the clock frequency does not require adjustment of the vector. Advantage of the FPGA to control the liquid crystal display with its speed and stability by a growing body of research. This design used in LCD model is HS162-understand display principles and pin structure on the basis of the LCD is divided into eight, so that only part of it to be displayed. Our main design is a part of the programming of the display module, in order to simplify the design, the part is divided into program control display and the fo
