  • Publication number: 20230216496
    Abstract: A proximity sensor is provided with multiple channels and a proximity sensor chip (IC) connected to the multiple channels through a sensing line. The proximity sensor chip (IC) includes an internal temperature sensor, senses a first sensing value through the multiple channels, senses a second sensing value through the internal temperature sensor, and compensates the first sensing value through addition or subtraction of the second sensing value with respect to the first sensing value. The internal temperature sensor includes: a clock signal generator including a first oscillator and generating first clock signals variable according to temperature characteristics; and a temperature compensator generating second clock signals according to a setting condition corresponding to the first clock signals generated from the clock signal generator and outputting the second sensing value by counting the second clock signals through a second oscillator generating reference clock signals independent of temperature change.

  • Patent number: 11499844
    Abstract: A proximity sensor having improved environmental compensation performance and an environmental compensation method in the proximity sensor are disclosed. The environmental compensation method and the proximity sensor advantageously reduce processing time, algorithm operation time, and power consumption by previously setting sensing values before sensing of sensors unlike a typical method in which compensation is carried out by multiplying factors obtained through software. Further, the environmental compensation method and the proximity sensor have an advantage of accurate compensation not only for linearly varying environmental factors but also non-linearly varying environmental factors.

  • Publication number: 20200097108
    Abstract: Disclosed are an electronic device including a narrow bezel and a proximity sensing method for the electronic device. The electronic device includes: a first sensor configured to be arranged in a first area which is at least part of the non-display area of a front surface including a display, and to detect first capacitance between a first object in front of the front surface and the first sensor; a second sensor configured to be arranged in a first side surface adjacent to the first area, and to detect second capacitance between a second object in front of the first side surface and the second sensor; and a processor configured to generate sensing information by compensating the first capacitance based on the second capacitance, and to determine the proximity of the first object based on the sensing information.
