Abstract
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.
