Abstract
Example embodiments are directed to a light-sensing circuit, a method of operating the light-sensing circuit, and a light-sensing apparatus including the light-sensing circuit. The light-sensing circuit includes a light-sensitive oxide semiconductor transistor that senses light; and a switching transistor connected to the light-sensing transistor in series and configured to output data. During a standby time, a low voltage is applied to the switching transistor and a high voltage is applied to the light-sensitive oxide semiconductor transistor, and when data is output, the high voltage is applied to the switching transistor and the low voltage is applied to the light-sensitive oxide semiconductor transistor.
