Abstract:
1. An active matrix display device comprising: a plurality of gate lines; a plurality of drain lines; a plurality of pixel electrodes arranged at intersections between the plurality of gate lines and the plurality of drain lines; a drain line driver connected to the plurality of drain lines for selecting a predetermined drain line from the plurality of drain lines and providing the selected drain line with an image signal; a gate line driver connected to the plurality of gate lines for selecting a predetermined gate line from the plurality of gate lines and providing the selected gate line with a gate signal; a plurality of level shifters connected to the drain line driver and/or the gate line driver, each level shifter boosting a clock signal and providing the boosted clock signal to the associated driver, wherein the drain line driver and the gate line driver each include a plurality of shift registers at least one of which is connected to each of the level shifters, and wherein each shift register provides the adjacent shift register with a scan signal based on the boasted clock signal; and a plurality of switches connected to the plurality of level shifters, wherein each switch selectively supplies an associated level shifter with a power supply voltage in response to the scan signal from the shift register that is connected to the associated level shifter and in response to the scan signal from the shift register connected to the level shifter that is adjacent to the associated level shifter.
