Abstract:
1. A drive system of a display device, comprising: a plurality of pixels provided in a matrix form comprising rows and columns, the pixels having corresponding current drive elements therein; a plurality of current conversion circuits converting digital display signals that the drive system receives into analog currents corresponding to the digital display signals, the number of the current conversion circuits being equal to the number of the columns; a first selector circuit supplying the digital display signals to the respective current conversion circuits; and a second selector circuit receiving outputs of the current conversion circuits and supplying the outputs to the respective pixels, wherein the first and second selector circuits are configured such that during one field period one of the current conversion circuits supplies an output thereof to a pixel element corresponding to one of the columns in a horizontal scanning of said one field period and supplies the output thereof to a pixel element corresponding to another of the columns in another horizontal scanning of said one field period subsequent to the horizontal scanning.
