<P>PROBLEM TO BE SOLVED: To supply a desired current to each pixel row without increasing an input video signal amplitude and losing display quality. <P>SOLUTION: The display device has a matrix display part, where the light emitting devices of RGB and the pixel circuits thereof are arranged in row and column directions, and a plurality of column control circuits 1 for generating current data signals from input video signals. Also, the display device has data lines that transmit the current data signals from the column control circuits 1 to the pixel circuits in the columns of the matrix display part. The data lines are divided into a plurality of sets by using R, G, B column data lines as one set. The column control circuits 1 comprise the plurality of sets that are formed by four column control circuits as one set. The four column control circuits comprise first and second column control circuits Gm1 and Gm2, which output R, G current data signals to R, G column data lines, and third and fourth column control circuits Gm3 and Gm4, which are connected in common with B column data lines and output the current data signals of the same B. <P>COPYRIGHT: (C)2007,JPO&INPIT |
