Problems solved by technology

[0005] In order to solve the technical problems in the prior art that the assembly accuracy of the panel structure after boxing cannot be directly seen, and the misalignment displacement of the photoresist spacer (PS, Photo Spacer) in the panel using COA technology is difficult to obtain accurately To solve the technical problem, the present invention provides a display panel, wherein the black matrix layer of the display panel includes a horizontal portion and a protruding portion arranged on the horizontal portion, and the protruding portion is connected to the metal layer of the display panel. Partially opposite, the metal layer is provided with a scale structure for measuring the protruding part, and the protruding part is located in the display area of ​​the display panel

Embodiment 1

[0036] The specific embodiments disclosed in the present invention only show the structural parts related to the present invention, and other specific parts are not limited. Those skilled in the art can know the specific structures of other parts that the display panel should have according to the prior art, namely In this specific implementation manner, some existing technologies of the display panel will not be described in detail. Those skilled in the art can understand that what is shown in the drawings in this embodiment is a part of the display panel corresponding to a sub-pixel structure area.

[0037] Such as Figure 7 As shown, it is a schematic diagram of a display panel within the range of a sub-pixel structure; the pixel structure design in the display panel adopts DBS (Data-line BM less Structure), that is, the position corresponding to the long side of the sub-pixel structure The black matrix (BM) in the long side direction is replaced by an ITO voltage shield (...

Embodiment 2

[0044] Such as Figure 9 As shown, non-DBS (Data-line BM lessStructure) is adopted in the design of the pixel structure in the display panel, that is, there is a black matrix layer (BM) at the positions of the long side and the short side of the sub-pixel structure, and those skilled in the art A conventional application of a black matrix layer (BM) is known. Figure 9 structure in Figure 7 The difference in the structure is only in the black matrix structure, and the other parts are the same as Figure 7 In this embodiment, the display panel adopts a non-DBS pixel structure design (this kind of pixel structure design is mostly used in flat products, and the short side and long side direction are all blocked by BM), that is, from Figure 9 It can be seen that the long side (the side in the vertical direction) and the short side (the side in the horizontal direction) of the metal layer are uniform black matrix layer (BM),

[0045] The black matrix layer on the short side in...

Abstract

The invention provides a display panel. A black matrix layer of the display panel comprises a horizontal part and a protruding part arranged on the horizontal part. The protruding part is opposite toa metal layer of the display panel. A ruler structure for measuring the protruding part is arranged on the metal layer. The protruding part is located in a display area of the display panel. By meansof the display panel, the relative displacement between an array substrate and a color filter substrate can be precisely seen, and therefore the assembling precision of the boxed panel structure and the staggered displacement of photo spacers in a panel of a COA technology are obtained. The obtained result can be used for preparing important reference values for subsequent panels, and therefore the product yield is increased, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of manufacturing liquid crystal panels and liquid crystal displays, in particular to a display panel. Background technique [0002] As a common display device, liquid crystal display has deeply entered people's daily life. As a result, liquid crystal display technology has developed more rapidly. TFT-LCD (Thin Film Transistor Liquid Crystal Display) has the advantages of small size, low power consumption, no radiation, and relatively low manufacturing cost, and has become the current mainstream display device. [0003] In the prior art, a common TFT-LCD is obtained by an array (Array) substrate and a color filter (Color Filter, CF for short) substrate through liquid crystal panel assembly technology (cell assemble technology). In the assembly, a concept of assembly process (Assembly) is involved, specifically referring to that the pixels of the array substrate can be normally and accurately aligned with the color fi...
