Abstract: An electroluminescent display apparatus including a pixel connected to a detection line; a panel driving circuit configured to off-drive a driving element included in the pixel in a detection interval; a reference voltage generating circuit configured to supply a detection reference voltage to the detection line prior to the detection interval, generate a first comparator reference voltage which is higher than the detection reference voltage in the detection interval, and generate a second comparator reference voltage which is lower than the detection reference voltage in the detection interval; a comparator configured to compare the first comparator reference voltage with a voltage of the detection line to generate a first comparison output at a first timing of the detection interval and comparing the second comparator reference voltage with the voltage of the detection line to generate a second comparison output at a second timing of the detection interval; and a logic circuit configured to determine an occurrence of a defect of the pixel based on the first comparison output and the second comparison output and to perform dark spot processing of the defective pixel.

Abstract: A reflective display device is disclosed, which includes first and second substrates facing each other, each of which includes a display area and a reflective area; a display element provided in the display area; and a reflective control element provided in the reflective area, controlling reflectance of externally incident light. The reflective display device may improve a contrast ratio by controlling reflectance of a reflective area when an image is displayed.

Abstract: Disclosed is a transparent display device including an electrochromic element. The electrochromic element includes an electrochromic layer, a counter layer, and an electrolyte layer. An image is displayed through an oxidation-reduction reaction, and the display device is in a transparent mode when a voltage is not applied. The electrochromic layer and the counter layer may further include a core material for changing a color at a high speed.

Abstract: An electroluminescent display apparatus can include a display panel including the one or more subpixels connected to a data line, a gate line, and a low-level power line. The display apparatus can further include a comparator connected to the one or more subpixels through the data line and the low-level power line to compare a first input voltage from the data line with a second input voltage from the low-level power line to generate a comparison output. The first input voltage is a reference voltage, and the second input voltage is a voltage of a specific node of the one or more subpixels capable of being shifted from an initialization voltage.
