Patent ID: 8305325

Claim:
A color display apparatus comprising: a display unit comprising electro-optical elements emitting a plurality of colors, the electro-optical elements arranged in a row direction and a column direction, scanning lines provided in respective rows of the electro-optical elements to select respective rows, and data lines provided in respective columns and supplying data signals to electro-optical elements in the row which the scanning lines select; conversion circuits, each of which receives a digital video signal and converts the digital video signal to an analog video signal, with a conversion circuit provided for each color of the color display apparatus; a first dispersion circuit for receiving the analog video signals outputted from the conversion circuits and exchanging an arrangement of the analog video signals to output to bus lines; column drive circuits which sample the analog video signals in the bus lines in a time sharing manner, and generate and output the data signals; and a second dispersion circuit for receiving the data signals outputted from the column drive circuits and exchanging an arrangement of the data signals to output to the data lines, wherein the exchanging of the data signals by the second dispersion circuit restores the exchanging of the arrangement by the first dispersion circuit so that the analog video signal for each color of the color display apparatus is output to the data line corresponding to that color.
