Abstract

A method of switching a control voltage of a photo sensor cell for a photo sensor includes when the photo sensor cell is switched from a turned-off state to an turned-on state, sequentially switching the control voltage to at least one first voltage provided by at least one first voltage supply, and switching the control voltage to a first target voltage provided by a first charging pump circuit; and when the photo sensor cell is switched from the turned-on state to the turned-off state, sequentially switching the control voltage to at least one second voltage provided by at least one second voltage supply or a ground voltage, and switching the control voltage to a second target voltage provided by a second charging pump circuit.
