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.
