    Abstract: A display device includes a display panel including a plurality of pixels respectively connected to a plurality of data lines and a plurality of scan lines, a data driving circuit for driving the plurality of data lines, a scan driving circuit for driving the plurality of scan lines, and a driving controller for receiving a control signal and an image signal and controlling the data driving circuit and the scan driving circuit such that an image is displayed on the display panel. The driving controller identifies a first region and a second region of an image to be displayed on the display panel based on the image signal and provides the data driving circuit with an image data signal obtained by compensating for the image signal to be provided to pixels adjacent to the second region among pixels corresponding to the first region as a compensation value.

    Abstract: A display apparatus includes an integral integrated circuit and a display panel. The integral integrated circuit includes a gate channel which outputs a gate primitive signal and a data channel which outputs a data voltage. The display panel includes a level shifter which amplifies the gate primitive signal to generate a gate signal. The display panel is configured to display an image based on the gate signal and the data voltage. The display panel includes a first gate line extending in a first direction and a second gate line extending in a second direction. The second direction is different from the first direction. The second gate line is connected to the first gate line. The level shifter is connected to the second gate line.

    Abstract: A display apparatus includes a display panel, a gate driver, a data driver, a driving controller and a power voltage generator. The display panel displays an image based on input image data. The gate driver outputs a gate signal to a gate line. The data driver outputs a data voltage to a data line. The driving controller drives display areas of the display panel in different driving frequencies. The power voltage generator outputs a data power voltage to the data driver. The driving controller outputs an output data enable signal including a writing period having an active signal and a holding period having an inactive signal for the respective display areas. The power voltage generator generates the data power voltage having a high power voltage level during the writing period and a low power voltage level in at least a portion of the holding period.

    Abstract: The present disclosure presents an electronic device. The electronic device may include a display panel, an input sensor, a first antenna, and a second antenna. The display panel includes a display region and a non-display region adjacent to the display region. The input sensor is disposed on the display panel and overlapped with a first region of the display region. The first antenna and a second antenna are disposed on the display panel and are overlapped with a second region of the display region, and each of which includes a stretchable pattern. A first distance between opposite ends of the stretchable pattern of the first antenna may be different from a second distance between opposite ends of the stretchable pattern of the second antenna. The inventive concept may provide an electronic device including a stretchable antenna.
