  • Patent number: 9304616
    Abstract: The present disclosure provides a touch panel including a plate, a sensing layer, a border, and an optical compensation layer, wherein the plate has an upper surface and a lower surface opposite to the upper surface, wherein the lower surface is planned with a conducting wire region and a sensing region. The border is overlaid on the conducting wire region, and the sensing layer is disposed in the sensing region. An optical compensation layer is disposed on the border, and is located between the plate and the border. The border has a first color, which appears as a second color if a user sees the border through the optical compensation layer, and thus achieves diversification of the border color.

  • Publication number: 20130135224
    Abstract: A touch sensing panel is provided in the present disclosure. The touch sensing panel comprises a sensing pattern layer and a plurality of bridging wires disposed on the sensing pattern layer, wherein each bridging wire has a top surface with low reflectivity. The sensing pattern comprises a plurality of first sensing pads and a plurality of second sensing pads, wherein the plurality of first sensing pads are connected by the bridging wires to form first sensing arrays, the plurality of second sensing pads are connected by connection parts to form second sensing arrays, and the first sensing arrays are insulated from the second sensing arrays. Reflectivity of the top surfaces of the bridging wires is comparatively low and therefore light from external sources is not easily reflected by the bridging wires, thereby reducing the influence of light spots in image quality.
