摘要： A light sensing circuit using an oxide semiconductor transistor, a method of manufacturing the light sensing circuit, and an optical touch panel including the light sensing circuit. Because the light sensing circuit includes only one light sensor transistor and one switch transistor formed on the same substrate, a structure of the light sensing circuit is simplified. Furthermore, because the light sensor transistor and the switch transistor have the same structure, a method of manufacturing the light sensing circuit is also simplified. Also, since an optical touch panel or an image acquisition apparatus using the light sensing circuit uses the light sensing circuit having a simple structure and does not use a capacitor, the optical touch panel or the image acquisition apparatus may be made thinner and larger.
