  • Publication number: 20200159348
    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.

  • Patent number: 10345955
    Abstract: A touch sensor includes a driving electrode which includes at least two divided areas electrically separated from each other, wherein each divided area includes first patterns connected to each other in a first direction and second patterns extending from the first pattern in a second direction, and a receiving electrode which is formed on the same plane as the driving electrode in the second direction, wherein the driving electrodes are respectively connected to separate driving channels by driving electrode wirings for each divided area, such that it is possible to sense touch positions over the entire area only by a smaller number of channels. Thereby, it is possible to significantly reduce the bezel width, and may maintain excellent touch sensitivity while significantly shortening the touch recognition time.
