  • Publication number: 20230215307
    Abstract: A light emitting display device can include a display panel configured to display an image; a driver configured to drive the display panel; a controller configured to control the driver; and a defect sensing circuit configured to sense a current through a driving voltage line transmitting a driving voltage for driving of the display panel, and output a sensing value based on the current for determining whether an element in a subpixel of the display panel is defective.

  • Patent number: 10254579
    Abstract: A curved display device includes: first and second substrates having a first panel portion at a center thereof and having second and third panel portions at respective sides of the first panel portion; gate and data lines crossing each other to define a plurality of sub-pixels; a black matrix having a plurality of open portions corresponding to respective ones of the sub-pixels; and first to third color filters between the black matrix and the first substrate. The black matrix between the open portions has first to third black matrix widths in the first to third panel portions, respectively, and the open portion has first to third open portion widths in the first to third panel portions, respectively. Each of the second and third BM widths is equal to or greater than the first black matrix width, and the second and third BM widths are equal to each other.
