  • Patent number: 10547017
    Abstract: In an organic light emitting diode (OLED) display device and a method for fabricating the same, OLED pixels are patterned through a photolithography process, so a large area patterning can be performed and a fine pitch can be obtained, and an organic compound layer can be protected by forming a buffer layer of a metal oxide on an upper portion of the organic compound layer or patterning the organic compound layer by using a cathode as a mask, improving device efficiency. In addition, among red, green, and blue pixels, two pixels are patterned through a lift-off process and the other remaining one is deposited to be formed without patterning, the process can be simplified and efficiency can be increased.

  • Patent number: 10319792
    Abstract: A thin and lightweight display device is disclosed. The display device includes a black bridge electrically connected to a plurality of touch electrodes disposed on an encapsulation unit, wherein the black bridge is disposed on the encapsulation unit between color filters to also serve as a black matrix, with the result that a cell gap between the black bridge and an anode electrode is reduced when compared with a comparative example, thereby securing a wide viewing angle, and wherein the touch electrodes are disposed on the encapsulation unit, with the result that an additional bonding process is not required, whereby the process is simplified and cost is reduced.
