  • Colored photosensitive resin composition for preparation of color filter of solid-state image sensing device using 300 nm or less ultrashort wave exposure equipment, color filter using same, and solid-state image sensing device containing same
    Patent number: 8902522
    Abstract: Disclosed is a colored photosensitive resin composition for a color filter of a solid state imaging device using an ultra-short wavelength exposing device of 300 nm or less, a color filter and a solid state imaging device including the same. The colored photosensitive resin composition can fabricate a color filter having a micro-patterned colored pattern. The color filter can be advantageously applied to a solid state imaging device.

  • TOUCH SCREEN PANEL AND METHOD OF PREPARING THE SAME
    Publication number: 20140087064
    Abstract: A method for preparing a touch screen panel includes forming a non-conductive pattern on a non-display part on one face of a window plate, so that the thickness of the non-conductive pattern is decreased to produce a thin touch screen panel. In addition, this will prevent leakage of ink through the holes of the window plate, and improve the reliability of a conductive electrode pattern layer at a lateral side of the non-conductive pattern, thereby reducing failure rates.

  • TOUCH SCREEN PANEL AND METHOD OF PREPARING THE SAME
    Publication number: 20140075750
    Abstract: A touch screen panel and a method for preparing the same, and more specifically, a touch screen panel includes a window plate 311, a non-conductive color pattern 312 formed on a non-display part on one face of the window plate, and a non-conductive shielding pattern 313 formed on the non-conductive color pattern 312, so as to provide a non-conductive pattern having the desired colors and shielding effects, and to reduce failure rates during the formation of the non-conductive pattern, as well as a method for preparing the same.
