Patent ID: 7123227

Claim:
A television comprising: a source signal line driver circuit comprising at least one thin film transistor, over a substrate; a gate signal line driver circuit over the substrate; a plurality of pixel electrodes, each pixel electrode located in each region at which a plurality of source signal lines and a plurality of gate signal lines intersect; and a plurality of switching elements for driving the pixel electrodes, over the substrate; wherein the source signal line driver circuit has a plurality of D/A converter circuits, each D/A converter circuit converting a digital image signal into an analog image signal, a plurality of connection switching switches and a plurality of source line selection circuits; wherein each of the plurality of connection switching switches alternately connects first and second systems of grey-scale electric power supply lines to one of the plurality of D/A converter circuits; wherein each of the plurality of source line selection circuits selects the source signal line corresponding to the digital image signal, from among the plurality of source signal lines, synchronously with the timing at which the digital image signal is input to the D/A converter circuit; and wherein the analog image signal output from the D/A converter circuit is written out to the selected source signal line.
