  • Patent number: 10200033
    Abstract: In one embodiment, an apparatus may include a first mesh of conductive material covering an area corresponding to at least a portion of the touch sensor. The first mesh includes a number of mesh cells. Each of the mesh cells has a number of vertices. Each of the vertices has a substantially randomized location within an inner portion of one of a number of polygons. The polygons collectively and contiguously covers the area corresponding to at least a portion of the touch sensor. One or more dimensions of the polygons is based at least in part on a pre-determined distance threshold between one or more pairs of opposing vertices. The apparatus also includes a computer-readable non-transitory storage medium coupled to the touch sensor and embodying logic that is configured when executed to control the touch sensor.

  • Patent number: 8072673
    Abstract: A display apparatus according to an embodiment includes a first substrate including a plastic material, a second substrate facing the first substrate, and a coating layer formed on at least one surface of the first substrate. The coating layer includes a first compound having an acryl-based monomer and a second compound having a silicon derivative, and prevents reflection of light from the first substrate when light is provided to the first substrate. Thus, the display apparatus may have enhanced lightness (brightness) thereby improving the display quality.
