Abstract:
1. A display apparatus with a time domain multiplex driving circuit, comprising: a plurality of parallel scan lines arranged in a first direction, wherein the scan lines includes a first scan line; a plurality of parallel data lines arranged in a second direction which is perpendicular to the first direction, wherein the data lines includes a first data line; a first pixel coupled to the first data line and the first scan line; a second pixel coupled to first data line and the first scan line, wherein the first pixel and the second pixel are set on different sides of the first data line; a first switching device, set in the first pixel, for selectively transmitting a first data signal on the first data line to the first pixel, the first switching device including at least two thin film transistors and a first equivalent feed-through capacitor; and a second switching device, set in the second pixel, for selectively transmitting a second data signal on the first data line to the second pixel, the second switching device including at least one thin film transistor and a second equivalent feed-through capacitor; wherein the ratio between the capacitance of the first equivalent feed-through capacitor and the capacitance of the second equivalent feed-through capacitor is determined with respect to pixel capacitances and storage capacitances of the first and second pixels so tat the feed-through voltages of the first pixel and the second pixel are substantially equal when the first data signal and the second data signal are equal; wherein the feed-through voltages of the first pixel and the second pixel is made equal substantially by using overlapping area control on the thin film transistors of the first and second switching devices so that the capacitances of the first and the second equivalent feed-through capacitors are set according to the determined ratio.
