摘要：
A light-sensing apparatus in which a light sensor transistor in a light-sensing pixel is formed of an oxide semiconductor transistor for sensing light, a method of driving the light-sensing apparatus, and an optical touch screen apparatus including the light-sensing apparatus. The light-sensing apparatus includes a light-sensing pixel array having a plurality of light-sensing pixels arranged in rows and columns, and a plurality of gate lines which are arranged in a row direction and respectively provide a gate voltage to the light-sensing pixel. Each of the light-sensing pixels includes a light sensor transistor for sensing light and a switch transistor for outputting a light-sensing signal from the light sensor transistor, and gates of the light sensor transistors of the light-sensing pixels arranged in an arbitrary row are connected to a gate line arranged in a row previous or next to the arbitrary row.
