The traditional approaches of grayscale scanning are of low efficiency. Fractal scanning technique whose scanning efficiency reaches 100% overcomes this problem

providing a good solution to the big size and high grayscale of Flat Panel Display (FPD). This paper presents a control system with gamma correction based on fractal scanning method. The gamma correction was realized by lookup table (LUT) according to both FPD characteristic and visual characteristic.The verification was implemented by using a 3232 pixels light-emitting diode (LED) panel as display window of the 1 2801 024 pixels FPD. Theory and experiment results both show the method proposed in this paper could improve the FPDs visual effect.
