Driving method to improve display quality as current control with external circuitry

Image quality of FED (Field Emission Display) depends on uniformity of each pixel quality, because current FEDs have a passive matrix structure. If a pixel has a leakage path between gate and cathode, this affects neighboring pixels. The panel is activated by general flat panel driving scheme (push-pull method), image distortion such as a dark line pattern is observed according to the driving method. In this paper, this is simulated and cured by a new driving method for better image quality. The results from simulation and experiment are compared.
