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.

Abstract: The present application discloses a light sensor circuit, which comprises a photodiode and a capacitor unit. The cathode of the photodiode is controlled by a capacitive unit to maintain the same or close voltage level as the anode of the photodiode, which significantly reduces the effect of the dark current of the photodiode. Thus, the light sensor circuit can effectively maintain the performance and accuracy of an analog-to-digital converter applying the light sensor circuit. The circuit design difficulty and manufacturing cost are also significantly reduced.

Abstract: An operation method of an optical sensor comprising receiving an ambient light by a light-sensing device. Record a signal generated by the light-sensing device after receiving the ambient light by a operation unit. A flicker frequency of the ambient light is determined by the operation unit. A signal operation parameter is set according to the flicker frequency, and the signal operation parameter comprises a sampling time difference, which is the starting time interval of two corresponding integration time periods of a plurality of integration time periods. Furthermore, the light-sensing device and the operation unit start the calculation of the intensity of the ambient light, so that the flicker component of an ambient light source may be eliminated from the light sensing result to produce a stable sensing result.

Abstract: An operation method of a proximity sensor comprises: controlling a light-emitting element by a processing circuit. Such control includes a plurality of light source on and light source off operations. An optical sensor receives light and outputs a sensing signal corresponding to the intensity of the light. The processing circuit computes the sensing signal to produce a sensing result. The plurality of light source on and light source off operations includes a group having two light sources on operations and two light sources off operations. The two light sources on operations in the group or the two light sources off operations in the group are performed consecutively. In this way, the ambient light components of the light source on and off operations may cancel out each other to reduce the ambient light components contained in the sensing results.

The light wavelength of the second light emitted element is greater than the light wavelength of the first light emitted element.

When the display of an electronic device is in a light-up status, the control circuit switches on the first light emitted element to emit light; when the display of the electronic device is in a light-off status, the control circuit switches on the second light emitted element to emit light. Thus, it will prevent from the influence to the image of the display, and obtained the better sensing ability.
