    Abstract: A transceiver of the present inventive concept includes a transmitter and a receiver connected by a first line and a second line, and the transmitter includes a first encoder; a second encoder; and a transmission driver. The first encoder generates a first encoded data different from a first data during a first period and the second encoder generates a second encoded data equal to a second data during the first period, the second encoder generates the second encoded data different from the second data during a second period and the first encoder generates the first encoded data equal to the first data during the second period, and the first period and the second period are arranged to alternate with each other.

    IPC: G09G5/10

    Abstract: A tiled display includes a plurality of display devices respectively including a plurality of pixels, and a main controller that processes an input image signal to provide an image signal to the plurality of display devices. Based on distance data between adjacent display devices among the plurality of display devices, the main controller generates a corrected image signal that increases luminance near a boundary portion of the adjacent display devices.

    IPC: G09G3/32

    Abstract: A display device includes a pixel unit including first pixels connected to a data line and second pixels connected to the data line; a sensing unit overlapping the first and second pixels, the sensing unit including sensing electrodes; and a sensing controller for receiving a sensing signal from at least some of the sensing electrodes in accordance with a sensing enable signal having a sensing-on level. In a first frame period, at least two of first data voltages having different levels are applied through the data line to the first pixels and second data voltages having the same level as each other but different from the first data voltages are applied through the data line to the second pixels. In the first frame period, the sensing enable signal has a sensing-off level while the first data voltages are applied and the sensing-on level while the second data voltages are applied.

    IPC: G09G3/20

    Abstract: A display device includes a pixel unit including pixels connected to data lines and scan lines; a data driver disposed on one side of the pixel unit; a scan driver disposed on the one side of the pixel unit together with the data driver; and a controller which controls a slew rate and output timing of data signals output to the data lines based on a load of the scan lines and a load of the data lines. Each of the scan lines includes a main scan line extending in a first direction and connected to pixels in a corresponding pixel row; a first sub-scan line extending in a second direction and connected to the main scan line at a first contact point; and a second sub-scan line extending in the second direction and connected to the main scan line at a second contact point.
