Abstract: A light sensor status control method, includes: a processor (110) determines a display time period and a non-light-emitting time period in a image refresh cycle (501); and the processor (110) controls an optical transmitter of a light sensor (180G) to transmit an optical signal when pixels in a display area that is of an OLED display screen (194) and that corresponds to the light sensor do not emit light in the image refresh cycle, and the processor (110) controls the optical transmitter not to transmit an optical signal when the pixels in the display area that is of the OLED display screen (194) and that corresponds to the light sensor (180G) emits light (502). 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.

Abstract: A positioning method and apparatus for a mobile terminal, and a mobile terminal. After a first time period elapses, a main processor obtains M pieces of reliable navigation data from N pieces of buffered navigation data of the mobile terminal, and obtains K pieces of buffered position change data of the mobile terminal. The main processor combines the M pieces of reliable navigation data and the K pieces of position change data, to obtain position information of the mobile terminal in the first time period. The N pieces of navigation data are obtained through calculation by using a satellite navigation signal of the mobile terminal that is received during the first time period. The K pieces of position change data are obtained through calculation by using data that is obtained through monitoring by a sensor of the mobile terminal during the first time period.
