  • Patent number: 9000439
    Abstract: A homogenous thin film layer is patterned into a transparent conductive portion and a non-conductive portion without use of etching through the thin film. Instead, conductive fine-wires which are convertible in one embodiment into non-conductive fine-wires are selectively converted into the non-conductive form. In an alternate embodiment, the homogenous thin film layer which includes conductive fine-wires is provided in a curable liquid form and selected portions of the liquid formed are cured into being affixed to substrate. Remaining portions can be washed away. In the case of display devices using transparent electrodes, a thin thin-film transistor array substrate is provided where the initially homogenous thin film which is and then converted into patterned conductive and non-conductive sections forms the pixel-electrodes and/or common electrode of the display device.

  • Patent number: 8967042
    Abstract: A printing apparatus for manufacturing a spacer includes a printing plate and a printing roller. The printing plate has a plurality of receiving recesses formed thereon. The receiving recess has a generally elliptical shape. The receiving recesses are infiltrated with a plurality of beads. The printing roller transfers the beads onto its outer surface by rolling over the receiving recesses, and transfers the beads from its outer surface onto an external substrate. Thus, the spacers may maintain a distance between the first and second substrates stably, so that press characteristics may be enhanced and smear defects occurring when the display panel is pressed may be prevented.

  • Publication number: 20150009564
    Abstract: A polarizer includes a base substrate and a metal pattern disposed on the base substrate and forming a wire grid. The wire grid has a width and a height and spaced apart from adjacent wire grid by a separation distance. A pitch is a sum of the width and the separation distance. A fill factor is obtained by dividing the width by the pitch. The range of the fill factor is based on an extinction ratio of polarization and a transmittance of the polarizer.
