Description

The present application claims priority to Chinese Patent Application No. 201811057899.5 filed on Sep. 11, 2018, titled “array substrate and display panel”, the entire disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

BACKGROUND

The liquid crystal displays, which are currently widely used, generally have two substrates with a liquid crystal layer interposed therebetween, and a sealant is disposed between the two substrates to bond the two substrates and seal the liquid crystal layer between the two substrates.

In the existing display panel processes, the first process is the alignment layer process. In order to provide a certain alignment for the liquid crystal molecules between the two substrates, an alignment layer (Alignment Layer or Orientation Layer) is provided on each surface of the substrates, and the alignment layer is formed by providing an alignment groove on the alignment layer. After the alignment layer is disposed, a sealant is further provided to join the two substrates.

The alignment layer forming liquid can rotate polyimide (PI), and there are three common coating methods: a soaking mode, a letterpress printing mode, and an ink jetting method. Moreover, as glass sizes have grown, the ink jetting method has become a common means. However, the ink jetting method has problems of blur boundaries, difficulties in reasonably and precisely controlling the accuracy, and further causing poor coating. Therefore, in the processes, a plurality of dummy PS walls (DPSW) and a plurality of grooves are provided in the peripheral regions of the substrates, thereby preventing the alignment layer forming liquid, around the effective display region, from overflowing to the effective display region or the region close to the sealant, when the alignment layer forming liquid is coated on the substrates.

The basic structure of the liquid crystal display panel includes an array substrate 100, an opposite substrate 200, a sealant 106 and a liquid crystal layer 105. The array substrate 100 includes a substrate 101, an array part 102 disposed on the substrate 101, an alignment layer 103 disposed on the array part 102, and a blocking part 104 disposed at the substrate 101 and substantially surrounding the alignment layer 103, wherein the blocking part 104 has a height difference with regard to the surface of the substrate 101. As shown in FIG. 1, the alignment layer 103 is provided by coating an alignment layer forming liquid polyimide (PI) on the array part 102. The blocking part 103 includes several different structures, and may be designed according to different requirements, such as a groove, a partition wall provided by a photo spacer (PS), a color blocking wall in non-display regions, or a physical design consisted of at least one of the three components.

Please continually refer to FIG. 1, the center of the array substrate 100 is an effective display region, which includes a plurality of pixel regions, and each of the pixel regions is configured with a plurality of different color resists, wherein the color resists are different according to the specifications of the display panel, such as three color resists, four color resists or other designs with several color resists. The three color resists are for example respectively a red color resist, a green color resist and a blue color resist, the four color resists are for example respectively a red color resist, a green color resist, a blue color resist and a white color resist. The combination of various color resists may further include a yellow color resist or a color resist for other colors.
