    摘要: A cyclic orthogonal matrix with three rows and four columns is used to drive a simple-matrix liquid crystal panel. Three gradation palettes having different phases of ON/OFF data of intermediate gradations are generated. A frame-rate-control phase table for an entire screen of the liquid crystal panel is generated in which the three gradation palettes are distributed so that the sequence direction of the ON/OFF data of the three gradation palettes coincides with the circulation direction of data of the cyclic orthogonal matrix, and a predetermined gradation palette is assigned to each pixel of the liquid crystal panel. Frames of the frame-rate-control gradation system and column vectors of the cyclic orthogonal matrix are simultaneously updated field-by-field to perform drive control and gradation control of each pixel of the liquid crystal panel. The gradation display of each pixel of the liquid crystal panel is completed for 12 fields constituting the three frames of the frame-rate-control gradation system.
