  • Patent number: 10482802
    Abstract: A display apparatus includes a display panel configured to display an image. The display panel includes a plurality of gate lines and a plurality of data lines. A gate driving part is configured to output gate signals to the plurality of gate lines. A data driving part includes a plurality of channels configured to output data signals to the plurality of data lines. The plurality of channels is further configured to shift the data signals by M channel, where M is a positive integer, according to a driving mode selection signal for selecting a driving mode of the display panel.

  • Publication number: 20170278452
    Abstract: A display apparatus includes a display panel. The display panel includes a substrate including a display area and a peripheral area adjacent to the display area, and a pixel array disposed on the display area. The display apparatus further includes a driving chip mounted on the peripheral area and configured to provide a driving signal to the pixel array. The driving chip includes a plurality of pads that are electrically connected to the display panel and disposed along a first direction. The pads include an input pad and a conductive alignment pad having a shape different from a shape of the input pad.

  • Patent number: 9589527
    Abstract: A display device including a display panel, including a plurality of pixels, a driver circuit configured to display an image on the display panel in response to an image signal and a control signal, and a voltage generator configured to generate an analog driving voltage for an operation of the driver circuit in response to a voltage control signal. The driver circuit is configured to compare the image signal to ripple image patterns and is configured to output the voltage control signal to change a voltage level of the analog driving voltage, according to the result of the comparison.
