  • Patent number: 11183553
    Abstract: An organic light-emitting display device including: a substrate; a pixel electrode on the substrate; a pixel defining film on the pixel electrode and having a first opening at least partially exposing the pixel electrode; an organic light-emitting layer on the exposed portion of the pixel electrode; a common electrode on the organic light-emitting layer and the pixel defining film; an encapsulation layer on the common electrode; a black matrix on the encapsulation layer and having a second opening overlapping the first opening; and a plurality of first sensing lines on the black matrix and surrounding the pixel electrode in a plan view to define a pixel region. At least portions of the first sensing lines defining the pixel region do not overlap the common electrode in the pixel region to reduce the common electrode's influence on the touch sensing lines and improve touch sensitivity.

  • Patent number: 10644083
    Abstract: An input sensing unit includes a base including light-transmitting areas and non-light transmitting areas. A light absorbing pattern is provided corresponding to the non-light transmitting areas and is configured to absorb incident light. A sensing electrode overlaps the light absorbing pattern. The light absorbing pattern has an aperture for exposing a light-transmitting area of the light-transmitting areas. A boundary of the aperture and an outer boundary of the light-transmitting area are spaced apart from each other. The input sensing unit has improved viewing angle/luminance ratio and improved characteristics of reflective color.
