    Abstract: The present disclosure provides a liquid crystal display and a display module thereof, the display module includes a lower polarizer, a TFT array substrate, a liquid crystal layer, a color filter and a upper polarizer. The display module further includes a metal electrode layer arranged between the color filter and the liquid crystal layer, the metal electrode layer includes a dielectric layer and a metal wire grid layer, and the metal wire grid layer is arranged on a surface of the dielectric layer facing the liquid crystal layer. The metal wire grid layer is used as a common electrode layer of the display module, thus replacing the traditional transparent electrode ITO and avoiding the problem that the transparent electrode ITO easily causes brittle fracture during bending resulting in electrical abnormality and at the same time can improve the contrast of the entire liquid crystal display.

  • Patent number: 10627669
    Abstract: An optical film includes a prism part having a plurality of prism patterns obliquely arranged in rows on a multilayer-structured reflective polarizing part. The reflective polarizing part is configured to reflect light from a first polarization axis and transmit light through a second polarization axis perpendicular to the first polarization axis. The rows of the prism patterns are arranged at a predetermined angle of inclination relative to the second polarization axis to reduce a Moiré phenomenon. The optical film may be adopted in a liquid crystal display device including a backlight unit to transmit light to a liquid crystal panel. A first polarizing plate is disposed between the optical film and the liquid crystal panel, and has a transmission axis that coincides with the second polarization axis of the reflective polarizing part to maximize light transmission from the backlight unit to the liquid crystal display.
