  • Patent number: 11467698
    Abstract: A touch sensor includes a substrate and first and second touch sensor electrode layers. The first touch sensor electrode layer is disposed on a first surface of the substrate, and includes a first pad formed on an opposing surface to a surface in contact with the substrate. The second touch sensor electrode layer is disposed on a second surface of the substrate, exposes at least a portion of the surface in contact with the substrate to an outside of the substrate, and includes a second pad formed on the portion exposed to the outside of the surface in contact with the substrate. The first pad and the second pad do not overlap in a stacking direction.

  • Patent number: 11126286
    Abstract: A method of fabricating a window deco film includes forming a hard coating layer, forming a deco layer on the hard coating layer, forming a light-shielding layer on the deco layer, and forming an acryl-based coating layer on the hard coating layer before forming the deco layer, or on the light-shielding layer. The window deco film may have a remarkably reduced thickness, and thus an entire thickness of an image display device including a window substrate to which the window deco film is applied may be also reduced. Additionally, even when the window deco film is attached to a curved window substrate, a bubble may not be generated at a curved portion of the window substrate. A mura caused by a retardation or a phase difference due to the window deco film may be suppressed. Thus, the window deco film may have an improved transmittance.

  • Publication number: 20190095025
    Abstract: The present invention relates to a force touch sensor and a manufacturing method thereof. The force touch sensor according to the present invention includes a lower electrode layer bonded to a display, an upper electrode layer bonded to a polarizing plate, and a transparent dielectric layer bonded to the lower electrode layer and the upper electrode layer. According to the present invention, thin film characteristics and flexible characteristics may be improved, manufacturing costs and manufacturing time may be reduced, and manufacturing processes may be simplified and product yield may be improved by simplifying functional layers constituting the force touch sensor.
