  • Patent number: 10796126
    Abstract: A fingerprint sensing device comprises a plurality of sensing pads, a plurality of data lines, a shielding layer, and a plurality of auxiliary voltage lines. The data lines are separately and electrically connected to the sensing pads, and configured to provide a sensing voltage to the sensing pads. The shielding layer is disposed between the sensing pad and the data lines. The auxiliary voltage lines are separately and electrically connected to the sensing pads, configured to provide an auxiliary voltage to the sensing pads. The auxiliary voltage is different from the sensing voltage. When a first sensing pad receives the sensing voltage, a second sensing pad adjacent to the first sensing pad receives the auxiliary voltage.

  • Patent number: 10628652
    Abstract: A sensing method of a fingerprint sensor is provided. The fingerprint sensor includes a plurality of sensing pixels arranged in an array, and the sensing pixels respectively have a sensing electrode. The sensing method includes following steps. A required resolution of an identification requirement is determined; here, the identification requirement is received by the fingerprint sensor. If the number of pixels of the required resolution is less than or equal to the number of the sensing pixels, self-capacitance sensing is performed on the sensing pixels to provide a first fingerprint pattern. If the number of pixels of the required resolution is greater than the number of the sensing pixels, the self-capacitance sensing and mutual capacitance sensing are performed on the sensing pixels to provide a second fingerprint pattern.

  • Patent number: 10504407
    Abstract: A display panel includes a pixel block, a data circuit, and a data source. The pixel block includes a first sub-pixel coupled to a first data line, and N second sub-pixels. Each second sub-pixel of the N second sub-pixels is coupled to a corresponding second data line of N second data lines. The data circuit includes N switches. Each switch of the N switches is coupled to a corresponding second sub-pixel. When N voltage levels are sequentially outputted from the data source to the first data line and the N second data lines, the N switches are disabled sequentially.

  • Patent number: 8476932
    Abstract: A multiplex gate driving circuit includes plural driving modules. In comparison with the prior art, each driving stage of the driving module has less number of transistors. From the first to the seventh example, each driving stage is implemented by only four transistors. In the eighth example and the ninth example, each driving stage is implemented by only two transistors. In other words, the driving stage of the multiplex gate driving circuit has less number of transistors, thereby reducing the layout area of the invisible zone of the LCD panel.
