Patent ID: 6885359

Claim:
A display device comprising: a plurality of drain signal lines; a drain drive element outputting a horizontal scanning signal for selecting one of the drain signal lines; a plurality of gate signal lines; a gate drive element outputting a vertical scanning signal for selecting one of the gate signal lines; a plurality of pixel elements provided at locations of the device corresponding to crossings of the drain signal lines and the gate signal lines, the pixel elements forming a matrix configuration; and a plurality of retaining circuits provided for corresponding pixel elements, the retaining circuits each holding an image signal fed from one of the drain signal lines, wherein the gate drive element and the drain drive element are configured to select an arbitrary set of pixel elements so that only the image signals retained in the retaining circuits of the selected pixel elements are rewritten, and the drain drive element comprises a shift register generating the horizontal scanning signal in response to a horizontal start signal and a horizontal output enable element receiving the horizontal scanning signal from the shift register and outputting the horizontal scanning signal to one of the drain signal lines corresponding to the selected pixel elements in response to a horizontal output enable signal which is in synchronization with the reception of the the horizontal scanning signal of the one of the drain signal lines corresponding to the selected pixel elements.
