Pixel control signal driver

摘要

A pixel control circuit includes a first supply rail coupled to provide a first supply voltage. A second supply rail is coupled to provide a second supply voltage. A variable resistance circuit is coupled to the second power supply rail. A plurality of driver circuits is coupled between the first supply rail and the variable resistance circuit. Each one of the plurality of driver circuits is coupled to provide a control signal coupled to control a pixel circuit. The variable resistance circuit is coupled to provide a first resistance between the plurality of driver circuits and the second supply rail during a sampling operation of the pixel circuit. The variable resistance circuit is coupled to provide a second resistance between the plurality of driver circuits and the second supply rail during a non-sampling operation of the pixel circuit.
