Abstract:
A display apparatus includes a matrix display unit including light-emitting devices that emit light of one of a plurality of colors with a brightness corresponding to a current and pixel circuits that drive the light-emitting devices, a plurality of column control circuits that receive input image signals and generate and output current-data signals, and a plurality of data lines each provided for each column of the matrix display unit to transfer the current-data signal output from the column control circuit to one of the pixel circuits in the column. The light-emitting devices have different current-luminance efficiencies depending on colors of emitted lights, and the plurality of data lines are divided into sets of data lines, each set of data lines transferring the current-data signals of the plurality of colors to the pixel circuits, and the number of data lines in the set of data lines is equal to the number of colors. In addition, one set of the column control circuits, comprised of a number larger than a number of colors of the display unit, is provided for one set of the data lines, comprised of a number equal to the number of colors.
