摘要： A light sensing circuit, a method of controlling the same, and a touch panel including the light sensing circuit. In the method of controlling the light sensing circuit, including sensing light incident on a photodiode, generating current corresponding to the brightness of the sensed light, amplifying the current using a driving transistor, and outputting the amplified current, the ambient temperature is sensed, and a time period during which the light is sensed by the photodiode or the amplified current is output is controlled by the sensed ambient temperature. Thus, the sensitivity of the light sensing circuit may be constantly maintained without being influenced by the ambient temperature.
