Abstract: A display device is disclosed in which a luminance control device includes a temperature sensor that detects a temperature of a display device; an average picture level part that calculates an average picture level, which defines an average brightness of an image input into the display device; and a luminance control part that generates a temperature-dependent peak luminance, which varies with temperature and average picture level, based on a top gain curve defining how a maximum luminance decreases as the temperature of the display device rises and a bottom gain curve defining how a minimum luminance decreases as the temperature of the display device rises, wherein the luminance control part fixes the temperature-dependent peak luminance at a specific luminance level, regardless of changes in average picture level, at a specific temperature in a high-temperature range which is higher than a room-temperature range.

Abstract: An electroluminescent display device can include a substrate divided into a plurality of sub-pixels having an opening area and a non-opening area, a planarization layer disposed on the substrate, an anode disposed on the planarization layer, and a bank disposed on the anode and the planarization layer, the bank having an opening exposing a portion of the anode in the opening area. The electroluminescent display device has a light emitting unit disposed on the portion of the anode; a cathode disposed on the light emitting unit and the bank. A deposition blocking layer is disposed on the cathode in a portion of the non-opening area and the opening area, and a reflective layer disposed on the cathode in another portion of the non-opening area, in which the reflective layer does not overlap with the deposition blocking layer.
