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. Thereby, the problem that the interference between the display pixels and the circuit element under the display unit cannot be avoided when the refresh rate changes is solved.

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 optical sensor module and a packaging method thereof are disclosed, wherein the optical sensor module comprises a substrate having a light sensing element; and a housing made of a transparent material. The housing is connected to the substrate and covers the light sensing element. The housing has a light-receiving area facing the light sensing element, and the inner surface of the housing toward the substrate is provided with a light-shielding coating in a portion outside of the light-receiving area. In this way, optical components such as the light sensor can be effectively protected, and still retain the effect of avoiding noise light interference with the light sensor module.

Abstract: The present application relates to a method of operating a capacitance sensing device comprises: calculating a difference of a raw data compared to one of the raw data received in a previous data frame; and performing a comparison calculation based on the raw data and a stored baseline value to determine whether a proximity event has occurred. Under the proximity event, selects one of several baseline value update procedures based on the magnitude of the difference. Thus, the present application effectively avoids the problem of failure to update the baseline value when the object is close to the capacitance sensing device for a long period of time, which may lead to misjudgment of the capacitance sensing device.

Abstract: A light sensor and control method thereof, which controls the light sensor comprising a first light emitted element, a second light emitted element, a first light sensing element and a control circuit. The light wavelength of the second light emitted element is greater than the light wavelength of the first light emitted element. The control circuit is coupled to the first and second light elements and the first light sensing 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.
