  • Patent number: 10366658
    Abstract: An organic light emitting diode (OLED) display is discussed. The OLED display is capable of duty driving for controlling an emission duty of an OLED in one frame. One frame for the duty driving includes a programming period, an emission period, and a non-emission period. In the programming period, a first data voltage is applied to a gate node in response to a scan signal and a reference voltage is applied to a source node in response to a sensing signal. In the non-emission period, a second data voltage is applied to the gate node in response to the scan signal. The first data voltage corresponds to input video data to be applied to a first pixel. The second data voltage corresponds to input video data to be applied to a second pixel different from the first pixel.

  • Patent number: 10019950
    Abstract: A panel defect detection method and an organic light emitting display device. A region having a high probability of a panel defect is intensively sensed through panel defect detection based on sensing results of characteristic values according to subpixels on sensing subpixel lines in an amount equal to the number of sensing subpixel lines preset in specific regions rather than all regions of a display panel. Rates and accuracy in detection of panel defects can be improved.
