Design and Implementation of Graphics Dot Matrix LCD Based on FPGA

In order to meet the application needs of the front display of the high-performance electronic instrumentation,the scheme that a high-speed FPGA processor controlled low-speed LCD module was proposed.The characteristics of the LCD display module built-in T6963C was elaborated and the hardware interface circuit between FPGA and LCD TG240128A was given.According to the graphical display addressing mode and command setting method,the design of the LCD driver module was completed by using the Verilog HDL hardware language and the graphics display of the image data.The simulation test results show that the display driving circuit based on FPGA can generate the correct timing,send data according with T6963C controller instruction sequence and complete the image data display.The system can effectively solve the problems of the driver and display between high speed FPGA and low speed LCD,and has a certain applications reference value in the visual interface design.
