A Driving Circuit Scheme for Field Emission Display Devices

摘要

A driving circuit scheme for field emission display (FED) devices with high voltage was presented. The negative voltage driving chip is employed in the cathode driver circuit, and the positive voltage driving chip in the gate driver circuit, where can increase the output driving voltage amplitude. By using HV4622 for realizing the cathode driver and HV7620 for the gate driver, the maximum output driving voltage of 400 V is obtained. The performance of the driving circuits are tested by driving the FED device with resolution of 120×3×68, and the results shows that the driving circuit can meet the requirements of the high voltage devices.
