    Abstract: An optical sensing circuit includes a first light sensor, a second light sensor, a third light sensor, a capacitor, and a sampling circuit. The first light sensor, the second light sensor, and the third light sensor are respectively covered by a first color filter, a second color filter, and a third color filter. The first light sensor is coupled to the capacitor, the sampling circuit, and the third light sensor. The second light sensor is coupled to the first light sensor and is configured to receive a first sensing signal. The third light sensor is coupled between the first light sensor and a voltage source.

    Abstract: A display panel includes gate lines and a gate driver. The gate driver includes series coupled driving stages, in which an N-th driving stage of the series-coupled driving stages includes a driving unit and an input control unit. The driving unit transmits a first clock signal according to a control voltage level of a control node, so as to output a gate-driving signal. The input control unit transmits the gate-driving signal outputted from an (N−1)-th driving stage to the control nodes, so as to adjust the control voltage level to one of a first voltage level and a second voltage level. A predetermined time interval is present between a rising edge of the first clock signal and a falling edge of the second clock signal. During the predetermined time interval, the control voltage level is pulled to the first voltage level by the input control unit.
