  • Patent number: 10365515
    Abstract: A VA liquid crystal display panel based on BM-less technology and a manufacturing method thereof are provided. The VA liquid crystal display panel based on BM-less technology includes a color mixture prevention zone that is formed of a stacked arrangement of red color resist and blue color resist and is used in combination with a main photo spacer and a sub photo spacer that are formed of a black material as a substitute of a black matrix. Further, the color mixture prevention zone has a portion that corresponds to the main photo spacer and the sub photo spacer and includes a recess formed therein. The main photo spacer is in engagement with a bottom of the recess to increase a height difference between the main photo spacer and the sub photo spacer and thus expanding LC margin and ensuring product yield rate.

  • Publication number: 20190219865
    Abstract: The manufacturing method of the BPS array substrate allows a black matrix, main photo spacers, and sub photo spacers to be all arranged on an array substrate with the same manufacturing process, wherein thicknesses of color resist units are used to achieve a height difference between the main photo spacer and the black matrix and the thicknesses of the color resist units are also used, in combination with controlling of light transmission rate of the mask, to achieve a height difference between the sub photo spacer and the black matrix. The area of the black light-shielding film layer that corresponds to and forms the black matrix corresponds to an area of a mask that is a full light transmission area during an exposure process so as to be irradiated with a sufficient amount of ultraviolet light during exposure to undergo complete crosslinking reaction.

  • Publication number: 20180052347
    Abstract: The present invention provides a VA type COA liquid crystal display panel, and the first light shielding layer having red or blue color resist material and the common electrode above the first light shielding layer are correspondingly located above the gate scan line, and the common electrode is electrically coupled to the common electrode layer on the upper substrate, and thus, the voltage difference of the upper, lower substrates is 0 at the gate scan line. Moreover, the panel appears an often black state at the gate scan line because the liquid crystal is not driven by the voltage; besides, the second light shielding layer formed by stacking up two of the red, the green and the blue color resist materials is correspondingly located above the data line; accordingly, the black matrix is eliminated, and the panel aperture ratio is high.
