  • Publication number: 20210326559
    Abstract: Sensing pixels each store a sensing voltage level. A method for driving the plurality of sensing pixels includes providing a plurality of readout scan signals to the plurality of sensing pixels, and providing a plurality of reset scan signals to the plurality of sensing pixels. One of the plurality of readout scan signals enables one of the plurality of sensing pixels to output the sensing voltage level stored in the one of the plurality of sensing pixels. One of plurality of reset scan signals resets the sensing voltage level stored in one of the plurality of sensing pixels. One of the plurality of reset scan signals is generated by converting one of the plurality of readout scan signals with a level shift circuit or one of the plurality of readout scan signals is generated by converting one of the plurality of reset scan signals with a level shift circuit.

  • Publication number: 20200332559
    Abstract: A transmission structure includes: a turn button; a driven wheel including a wheel body and connecting parts having free ends or pushing blocks; and an actuating member including abutting parts corresponding to the free ends or the pushing blocks. When the driven wheel rotates, each of the free ends or each of the pushing blocks abuts against a corresponding one of the abutting parts. Also, the actuating member moves with a rotating shaft, and a latch connected to the rotating shaft displaces between a locked position and an unlocked position. When the driven wheel rotates, the latch does not displace and the actuating member cannot rotate. Also, each of the free ends or pushing blocks is still abutted by the corresponding one of the abutting parts and is curved elastically or deformed until the free end or the pushing block spans across the corresponding one of the abutting parts.
