Abstract: The present application relates to an electronic device comprising: a display unit, a display driver circuit and a circuit element. The display driver circuit is coupled to the display unit. The circuit element is placed under a display area of the display unit. The circuit element receives a dynamic refresh signal generated by the display driver circuit. The dynamic refresh signal contains a refresh rate information of the display unit. Thereby, the problem that the interference between the display pixels and the circuit element under the display unit cannot be avoided when the refresh rate changes is solved.

Abstract: The present application relates to a display system with a light sensor and a control method thereof. The display system comprises a display module and a light sensor. The display module comprises a driving circuit for generating a driving signal. Said driving signal comprises a plurality of periodic pulse waves. The OFF time of one of the periodic pulse waves is extended to an extended time which is greater than the OFF time of the remaining periodic pulse waves. This ensures that the sensing result of the light sensor may not include the contribution of display light.
