Abstract
A sensing circuit includes a sensor array, a first controller and a second controller. The sensor array is charged by a sensing signal corresponding to an external light in response to a driving signal during a first time period and discharged in response to a switching signal during a second time period. The first controller provides the driving signal to the sensor array. The second controller provides the switching signal to the sensor array.
