Abstract: A display device includes a display panel including a pixel that includes sub-pixels for emitting light in respective colors, and a driver configured to adjust a current amount flowing through the sub-pixels and to adjust an emission duty of the sub-pixels, drive one sub-pixel among the sub-pixels having a luminance with a first current amount and with a first emission duty when a color coordinate of an image expressed by the pixel is within a reference color space, and drive the one sub-pixel having the luminance with a second current amount that is greater than the first current amount and with a second emission duty that is less than the first emission duty when the color coordinate is outside of the reference color space.

Abstract: A display device includes a planarization layer disposed on a substrate, a first electrode disposed on the planarization layer and including silver (Ag), a contact preventing layer disposed on the first electrode, including a light absorbing material, and including a top surface and a side surface extending from an end of the top surface, and a pixel defining layer disposed on the contact preventing layer and including a bottom surface facing the top surface of the contact preventing layer, and a side surface extending from an end of the bottom surface. The first electrode includes a first region overlapping pixel defining layer. The contact preventing layer includes a second region overlapping the first region between the first electrode and the pixel defining layer. A first edge where the top and side surfaces of the contact preventing layer meet is located on the bottom surface of the pixel defining layer.

Abstract: Provided is a display device including a display panel, an optical sensor, a timing controller, a scan driver, a data driver, and an image controller. The timing controller controls an image refresh rate of the display panel based on are fresh rate control signal. Thus, the display device provides improved visibility.
