A display device, by detecting a subpixel which is a defect by using an electronic fuse electrically connected to a driving transistor disposed on a subpixel and performing a repair, a display device being capable of detecting a defect and repairing by a circuit driving of the subpixel can be provided. Thus, even in the case that a repair by a physical method is not possible according to types of the display device, by detecting a defect of the subpixel and performing a repair, an image quality deterioration due to the defect of the subpixel can be prevented.

Display device

An electroluminescent display device comprises first to third subpixels each of which including a contact area and a light emission area, each subpixel provided with a first electrode, the first electrode extending from the light emission area to the contact area of each of the first to third subpixels; a first reflective layer provided in the light emission area of the first subpixel and electrically insulated from the first electrode of the first subpixel; a second reflective layer provided at least in the light emission area of the second subpixel; and a third reflective layer provided at least in the light emission area of the third subpixel.

Electroluminescent display device including reflective layer

A display panel sets a focus area per frame, based on focus area setting information and focus area reference line information received from the outside, control the number of gate lines simultaneously driven according to the focus area, and display a rendered image per focus area, thereby preventing the quality degradation of the image perceived by the user and increasing the frame rate of the display panel, and enhancing the quality of the virtual reality experience provided by the virtual reality device.

Display device and virtual reality device

A micro display device and a display integrated circuit are provided. Embodiments of the micro display device includes: a silicon substrate; a pixel array including a plurality of sub-pixels arranged in a pixel array zone of the silicon substrate; and driver circuits positioned in a circuit zone disposed around the pixel array zone of the silicon substrate, in which all or some of transistors in the pixel array zone and transistors in the circuit zone have different current-voltage transmission characteristics, thereby having excellent driving performance and display performance.
