Abstract: A display apparatus includes a display panel, a gate driver, a data driver, an emission driver and a driving controller. The display panel includes a gate line, a data line, an emission line and a pixel electrically connected to the gate line, the data line and the emission line. The gate driver outputs a gate signal to the gate line. The data driver outputs a data voltage to the data line. The emission driver outputs an emission signal to the emission line. The driving controller determines a number of emission in a single frame of the emission signal according to a luminance of a display image.

Abstract: A display device includes a display panel, a dimming controller, and a panel driver. The display panel includes a plurality of pixels. The dimming controller generates at least one temporary voltage set by performing a first interpolating operation using a (j)th band voltage set and a (j+1)th band voltage set among first through (i)th band voltage sets corresponding to first through (i)th dimming bands, respectively, and generates a grayscale gamma voltage set corresponding to target luminance by performing a second interpolating operation using the temporary voltage set and the (j)th band voltage set. The panel driver drives the display panel by converting image data into a data signal based on the grayscale gamma voltage set and by providing the data signal to the pixels.

Abstract: A display device includes a display panel, a window, a metal layer, and a first conductive tape. The display panel includes a display area, a non-display area, and a bending area disposed between the display area and the non-display area and bent such that the non-display area overlaps the display area. The window is disposed on a first surface of the display panel and includes a protruding portion overlapping the non-display area. The metal layer is disposed on a second surface of the display panel. The second surface is opposite to the first surface. The first conductive tape connects the protruding portion of the window to the metal layer.
