Abstract:To solve the time redundancy of FPD gray scale imaging process,the fractal principle is firstly applied to the FPD scanning system in this paper,and the optimal scanning architecture is educed and its fractal model is proposed.Firstly,an optimal topology is constructed for digital display system whose memory space is incised into several sub-partitions with different time dimensions.Then,we established the fractal scanning model used in "time gray scale" and "sub-partition" topology,and deduced the fractal dimension of FPD discrete space.Based on the fractal model,the self-similar fractal scanning of time gray scale is carried out in every sub-partition.This paper proved the optimization of the fractal scanning architecture in theory,and the experimental results also indicated that it could raise the scanning efficiency,improve the imaging quality apparently without changing the scanning frequency of current digital flat panel display systems.
