Design of LCD Driver Controller for AT056TN04

Duo to the denser circuit,better workmanship,higher cost,the low cost color analog screen is preferred in the production of test and measurement equipments.A driving controller based on FPGA for analog screen is designed.It implements the AT056TN04 driving,the refresh of LCD,and external user interface.Simulations and system test results show that the design works well in the display of 8 kinds of basic colors.The designed driving overcomes both the monotony of monochrome LCD module and the high price of the real color digital LCD module.By appropriate adjustment,it can be easily applied to other LCD module and can be widely used in the industrial instrumentations.
