摘要： In one embodiment, a light-sensing apparatus includes a light-sensing pixel array that has a plurality of light-sensing pixels arranged in rows and columns; and a gate driver configured to provide the light-sensing pixels with a gate voltage and a reset signal that have inverted phases. Each of the light-sensing pixels includes a light sensor transistor configured to sense light and a switch transistor configured to output a light-sensing signal from the light-sensor transistor. The gate driver includes a plurality of gate lines connected to gates of the switch transistors, a plurality of reset lines connected to gates of the light sensor transistors, and a plurality of phase inverters each connected between a corresponding reset line and a gate line. Thus, when a gate voltage is applied to one of the plurality of gate lines, a reset signal with an inversed phase to the gate voltage may be applied to a corresponding reset line.
