An example electronic device includes: a housing: a display including a plurality of signal lines; an optical sensor module including first and second light emitting elements respectively overlapping first and second signal lines, and a light receiving element configured to collect light from the first and/or second light emitting elements that is reflected and received from an external object; and a processor. The processor is configured to control the first light emitting element based on an off-time point of time of the first signal line corresponding to brightness of the display such that the first light emitting element emits light at a first light-emitting point of time, and to control the second light emitting element based on a time difference between off-time points of time of the first and second signal lines such that the second light emitting element emits light at a second light-emitting point of time.

A high-compatibility dimmer circuit is provided, which includes an impedance inspection avoidance module, a dimming module and an alternating-current input module. The impedance inspection avoidance module is connected to a load via an output end. The dimming module is connected to the impedance inspection avoidance module and includes a control unit. The alternating-current input module is connected to the dimming module, and converts an input alternating voltage into a pulsating direct voltage so as to power the load and the dimming module. When the load is driven, the control unit starts timing and switches the impedance inspection avoidance module after a predetermined time period. In this way, the dimming module can directly power the load and perform dimming for the load according to a dimming signal.
