Abstract
A light sensor status control method, includes: a processor () determines a display time period and a non-light-emitting time period in a image refresh cycle (); and the processor () controls an optical transmitter of a light sensor (G) to transmit an optical signal when pixels in a display area that is of an OLED display screen () and that corresponds to the light sensor do not emit light in the image refresh cycle, and the processor () controls the optical transmitter not to transmit an optical signal when the pixels in the display area that is of the OLED display screen () and that corresponds to the light sensor (G) emits light (). Therefore, a problem that the screen blinks because the light sensor emits infrared light is alleviated, and a display effect of the screen is improved.
