Claim 9:
10. The device of claim 1,
wherein the data-scan integration chip further includes a plurality of data output pads coupled to a plurality of data lines of the display panel, and a plurality of scan output pads coupled to a plurality of scan lines of the display panel,
wherein the shared level shifter array includes:
a plurality of level shifters;
a shifter input switch array which couples output terminals of the latch array to input terminals of the plurality of level shifters in response to a selection signal, and couples output terminals of the second shift register to the input terminals of the plurality of level shifters in response to an inverted selection signal; and
a shifter output switch array which couples output terminals of the plurality of level shifters to input terminals of the digital-to-analog converter array in response to the selection signal, and couples the output terminals of the plurality of level shifters to input terminals of the shared output buffer array in response to the inverted selection signal, and
wherein the shared output buffer array includes:
a plurality of output buffers;
a buffer input switch array which couples output terminals of the digital-to-analog converter array to input terminals of the plurality of output buffers in response to the selection signal, and couples output terminals of the shared level shifter array to the input terminals of the plurality of output buffers in response to the inverted selection signal; and
a buffer output switch array which couples output terminals of the plurality of output buffers to the plurality of data output pads in response to the selection signal, and couples the output terminals of the plurality of output buffers to the plurality of scan output pads in response to the inverted selection signal.
