High-resolution LCD is widely used in smart handheld device and electronic test equipment

and the design of its driver is becoming a hotspot in current research. The system architecture of electronic test equipments

such as digital oscilloscope

is usually based on FPGA&DSP. Therefore it has no dedicated processor serve for the LCD driver

and the traditional methods of LCD driver based on FPGA

is unable to meet the requirement of the refresh rate for its limited bus rate. To solve this problem

this paper describes a design of high-resolution LCD direct driving method based on FPGA-chip ODDR interface technology. The system is designed with FPGA as the core driver module

and DSP as the control module and the corresponding peripheral circuit. Processing display image with joining data together

it implements the driver and control of high-resolution LCD. Experimental results indicate that by modifying the frequency of line and field parameters of FPGA display module

the method is also suit to driver and control the multiple-resolution LCD with high reliability and easy to implement.
