  • Light-emitting display and method of driving the same
    Patent number: 11030951
    Abstract: A light-emitting display includes a display panel, a first circuit, and a second circuit. The display panel comprises a pixel. The first circuit supplies a data voltage to a data line for the pixel. The second circuit performs a sensing operation for sensing a sensing line for the pixel and outputs a voltage required for the sensing operation, and outputs a noise removing voltage for cancelling out noise formed on the sensing line during the sensing operation.
    Type: Grant
    Filed: December 9, 2019
    Date of Patent: June 8, 2021
    Assignee: LG Display Co., Ltd.
    Inventors: Changwoo Lee, Jaeik Yoo, Osung Do

  • Organic light emitting display and sensing method therefor
    Patent number: 10089928
    Abstract: The sensing method for an organic light-emitting display comprises: defining a pixel group comprising a reference pixel and two or more valid pixels, among a plurality of pixels arranged on a horizontal line; obtaining a black level current sensing value by applying a black level data voltage to the reference pixel; obtaining a current sensing value for a given gray level by applying a data voltage for the given gray level higher than the black level to each of the valid pixels; and obtaining a pixel current sensing value by subtracting the black level current sensing value from the current sensing value for the given gray level to eliminate common noise.
