  • Patent number: 12633271
    Abstract: A display device includes a processor configured to provide input image data, a display driver configured to display an image on a display panel based on the input image data and generate driving data for operating the display panel, and a memory configured to store the driving data and state data indicating whether communication with the display driver is possible. The display driver determines whether the state data is a first value when entering a sleep-out mode from a sleep-in mode, and changes the state data to the first value when the state data is not the first value.

  • Patent number: 12536934
    Abstract: A display device includes a display panel including a plurality of pixels connected to m data lines (where m is a positive integer greater than or equal to 3), and a data driver configured to supply a plurality of data signals to the m data lines. The data driver includes an output component and a switching component. The output component includes m source amplifiers respectively connected to the m data lines, and a first dummy source amplifier connected to a first dummy data line. The switching component includes m switches respectively formed on the m data lines, m?1 forward switches formed between adjacent data lines among the m data lines, m?1 reverse switches formed between the adjacent data lines, and a first dummy switch formed on the first dummy data line.

  • Publication number: 20250285567
    Abstract: A display device includes a display panel including a plurality of pixels, a first conductive ball connected to the display panel, and a driving integrated circuit connected to the first conductive ball and configured to generate and output a first gate driver control signal to the display panel through the first conductive ball, receive a first return signal of the first gate driver control signal from the display panel, wherein the first return signal corresponds to the first gate drive control signal provided to the display panel through the first conductive ball, and perform a first waveform comparing operation in which a waveform of the first gate driver control signal is compared with a waveform of the first return signal to determine whether the first conductive ball is oxidized.

  • Patent number: 7637648
    Abstract: A portable display device minimizes protrusions of a light emitting display panel, such as an organic light emitting display panel, and an integrated circuit to allows the thickness thereof to be reduced. The portable display device includes a light emitting display panel, such as an organic light emitting display panel. A metal plate is located on a rear surface of the organic light emitting display panel. A bottom chassis receives another light emitting display panel, such as a liquid crystal display panel and a backlight assembly. A first printed circuit board is located between the organic light emitting display panel and the bottom chassis. At least a part of either the organic light emitting display panel or the metal plate is arranged in opening portions of the bottom chassis and the first printed circuit board.
