  • Patent number: 10234712
    Abstract: A method produces a liquid crystal display. The display includes a plurality of pixels having sub-pixels that include one opening and one color layer. Some of the sub-pixels having the same color are continuously spaced in one direction. In the method, overlapping photolithographic patterns produce mask openings in which a color layer in two spaced adjacent sub-pixels is to be formed. The mask openings each have a size corresponding to two or more adjacent sub-pixels; and the number of sub-pixels of the same color that are continuously arranged in the one direction is at least twice the total number of sub-pixels of the same color included in each of the pixels.

  • Patent number: 10146127
    Abstract: A spacer manufacturing device is disclosed. The device includes a photo mask having a central light-transmitting region and a peripheral light-transmitting region disposed at a periphery of the central light-transmitting region; and an exposure device right opposite to the photo mask. Light emitted from the exposure device is irradiated to a negative photoresist material after passing through the photo mask, the light intensity passing through the peripheral light-transmitting region is less than the light intensity passing through the central light-transmitting region. A spacer is also disclosed. Only one exposure process is required to realize the spacer having a convex-shaped cross section. The process is simple and the manufacturing cost is low. At the same time, flatness of the convex shoulder of the spacer having a convex-shaped cross section is adjustable, which can satisfy the requirement for manufacturing spacers having different specifications.

  • Patent number: 10146078
    Abstract: An array substrate for a liquid crystal display panel is disclosed. The array substrate includes a first substrate, a Lower Temperature Polycrystal Silicon (LTPS) Thin-Film-Transistor (TFT) disposed on the first substrate, a color photoresist layer disposed on the LTPS TFT, and multiple photo spacers disposed above the color photoresist layer. A liquid crystal display panel including the array substrate and a second substrate disposed oppositely to the array substrate is also disclosed. The present invention utilizes the second substrate to be aligned with the LTPS TFT array substrate in order to form the liquid crystal display panel. Because the second substrate is a bare substrate (without a pattern), when the second substrate is aligned with the array substrate, the alignment precision is not under consideration. Accordingly, apertures ratios of the liquid crystal display panel do not have difference.
