Problems solved by technology

However, the currently existing charging of the BM (black matrix layer) leads to abnormal display of the panel, which has become a major problem in liquid crystal display products. Although some solutions have greatly improved the above-mentioned BM charging problem based on breakthroughs in structural design and materials, However, with the higher demand for high-end displays, the distance between the BM and the panel display area (Active Area) is reduced, which makes it easy to cause abnormal display in the display area after the BM is charged. For example, the panel L0 state is green, seriously affecting Product quality; at the same time, because BM is not only easy to be charged in the display factory, it is easy to cause BM to be charged during transportation and when the client assembles the system, which will lead to abnormal display of the panel. huge loss
[0003] Therefore, in the process of implementing the present application, the inventors found that the prior art has at least the following problems: the existing related display devices still have the problem that BM is easy to be charged, and then there are problems such as abnormal display and greenish L0

Embodiment 1

[0029] Depend on figure 1 It can be seen that the color filter substrate described in this application includes a base substrate 1 and a black matrix layer 2 disposed on one side of the base substrate 1; the side of the black matrix layer 2 away from the base substrate 1 is provided with a peripheral Columnar spacers 3, that is, peripheral columnar spacers 3 are arranged on the side of the color filter substrate facing the array substrate; the peripheral columnar spacers 3 are arranged correspondingly to the sealant coating area of ​​the color filter substrate , used to make the color filter substrate sealed and connected to the array substrate through the peripheral columnar spacer 3 and the sealant; the peripheral columnar spacer 3 and the surface of the black matrix layer 2 are both provided with an ITO layer 4, And make the ITO layer 4 contact with the ends of the peripheral column spacers 3 and the black matrix layer 2 at the same time. In this way, when the color filter...

Embodiment 2

[0037] refer to figure 2 Shown is a flowchart of an embodiment of the method for preparing a color filter substrate provided by the present invention. The preparation method of the color filter substrate includes:

[0038] Step 101, forming a black matrix layer on a base substrate; wherein, the base substrate may be a glass substrate; the process of forming the black matrix layer also includes forming a required black matrix pattern structure through a patterning process.

[0039] Step 102, forming pixel patterns and common electrodes on the base substrate on which the black matrix layer is formed;

[0040] Step 103, forming peripheral columnar spacers in the frame sealant coating area of ​​the color filter substrate; wherein, the peripheral columnar spacers and the main columnar spacers can be prepared through the same mask process, so that no additional mask craft.

[0041] Step 104 , forming an ITO layer on the black matrix layer and the peripheral column spacers, and m...

Embodiment 3

[0044] refer to image 3 Shown is a schematic structural diagram of an embodiment of the display panel provided by the present invention. The display panel includes an array substrate and any one of the color filter substrates described above. It can be seen from the figure that metal wires 7 are arranged in the coating area of ​​the sealant 8 of the array substrate 6; the ITO layer 4 is in contact with the metal wires 7, so that the black matrix layer 2 is connected to the The metal wires 7 are electrically connected, so that when the potential in the metal wires is zero, the charges in the black matrix layer 2 can be released. In addition, in the display area, RGB sub-pixels (11, 12, 13) and main column spacers are also arranged on the color filter substrate.

[0045] refer to Figure 4 As shown in FIG. 2 , it is a schematic structural diagram of the sealant region of the display panel in the prior art. Figure 4 Designed for common panel-to-box structures. The BM adopt...

Abstract

The invention discloses a color film substrate, a preparation method, a display panel and a display device. The color film substrate comprises a substrate body and a black matrix layer arranged on oneside of the substrate body; a peripheral columnar spacer is arranged on the side, away from the substrate body, of the black matrix layer; the peripheral columnar spacer is arranged corresponding toa frame sealing glue coating area of the color film substrate; ITO layers are arranged on the surface of the peripheral columnar spacer and the surface of the black matrix layer respectively, and theITO layers are in contact with the end of the peripheral columnar spacer and the black matrix layer at the same time. According to the color film substrate, the preparation method, the display panel and the display device, charges carried in the black matrix layer can be accurately and effectively eliminated, the problem that display is abnormal and green is avoided, and then the display effect isimproved; in addition, the adhesion force of the frame sealing glue area can be increased, so that the narrow bezel design is achieved.
