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.
