Abstract: The present application relates to a display system with a light sensor and a control method thereof. The display system comprises a display module and a light sensor. The display module comprises a driving circuit for generating a driving signal. Said driving signal comprises a plurality of periodic pulse waves. The OFF time of one of the periodic pulse waves is extended to an extended time which is greater than the OFF time of the remaining periodic pulse waves. This ensures that the sensing result of the light sensor may not include the contribution of display light.

Abstract: A light sensor and a control method thereof are disclosed. The light sensor comprises a light-emitting element, a first light-sensing unit and a second light-sensing unit. The light-emitting element generates an emission signal. The light-sensitive characteristic of the first light-sensing unit corresponds to a first wavelength range. The light-sensitive characteristic of the second light-sensing unit corresponds to a second wavelength range, which is different from the first wavelength range. In this way, when the emission signal is reflected by an object and received by the first light-sensing unit and the second light-sensing unit, the type of the object may be determined based on the difference between the signal sensed by the first light-sensing unit and the signal sensed by the second light-sensing unit.

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: The present application discloses an inertial sensor comprising a proof mass, an anchor, a flexible member and several sensing electrodes. The anchor is positioned on one side of the sensing, mass block in a first axis. The flexible member is connected to the anchor point and extends along the first axis towards the proof mass to connect the proof mass, in which the several sensing electrodes are provided. In this way, the present application can effectively solve the problems of high difficulty in the production and assembly of inertial sensors and poor product reliability thereof.
