TECHNICAL FIELD

[0001] The utility model relates to display screen field especially involves a display panel and display module. BACKGROUND

[0002] LTPS-LCD (low temperature polysilicon liquid crystal display) is a kind of display technology widely used in modern electronic equipment.The traditional LTPS-LCD product is composed of two glass substrates, and a layer of liquid crystal is sandwiched in the middle.

[0003] Typically, the patent literature with application No.202110588024.3 discloses a color film substrate, a manufacturing method of color film substrate and a display panel, wherein the color film substrate includes a substrate, a black matrix layer and a spacer.The black matrix layer is provided on one surface of the substrate and has a plurality of light transmission zones for setting color resist.The spacer is provided on the side of the black matrix layer away from the substrate, and extends along the periphery of the light transmission zone and separates the adjacent two light transmission zones.The technical scheme aims to avoid the mutual interference of liquid crystals corresponding to adjacent pixels, thereby ensuring the display effect.

[0004] The above prior art shows the color film substrate, black matrix and other structures, and solves the problem of mutual interference of liquid crystals corresponding to adjacent pixels, but there are still limitations in specific implementation, as follows:

[0005] The substrate has a black matrix layer and a spacer, which need to be made in the same position during manufacturing, and the manufacturing cost is high.

[0006] The subsequent color filter and array substrate are mainly aligned and attached by vacuum attachment equipment, so the alignment accuracy of the two is largely dependent on the accuracy of the vacuum alignment equipment.If the alignment accuracy is slightly deviated, the support spacer cannot be accurately aligned to the black matrix, and the transmittance is lost.

[0007] Therefore, how to solve the above-mentioned problems of the prior art has become the subject to be studied and solved by the utility model. UTILITY MODEL CONTENT

[0008] Therefore, it is necessary to provide a display panel and display module to solve the above technical problems.

[0009] To solve the above technical problems, the utility model adopts the technical scheme as follows:

[0010] A display module, comprising a color film substrate and an array substrate arranged oppositely, the color film substrate comprises a CF substrate and a plurality of color resistance blocks arranged in a rectangular array on the surface of the CF substrate, each of the color resistance blocks is arranged in a single grid of a grid area; the array substrate is provided with a plurality of black spacing strips on the side surface facing the color film substrate, which are arranged corresponding to the grid area.

[0011] Further, the longitudinal section of the black spacing strip is rectangular.

[0012] Further, the longitudinal section of the black spacing strip is inverted trapezoidal.

[0013] Further, no shading object is arranged in the grid area, which is a light-transmitting groove.

[0014] Further, the color resistance block is a color color resistance.

[0015] Further, the forming material of the black spacing strip is resin.

[0016] Further, the color film substrate further comprises a planar layer, which is arranged on the side of the CF substrate facing the array substrate, and the planar layer covers the color resistance block.

[0028] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment, obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor should belong to the protection scope of the utility model.

[0029] As described in the background, there is a black matrix layer and a spacer on the substrate, which needs to be made in the same position when making two different components, and the manufacturing cost is high. The subsequent color filter and array substrate will mostly rely on the vacuum laminating device for alignment and lamination, so the alignment accuracy of the two is largely dependent on the accuracy of the vacuum alignment device. If the alignment accuracy is slightly deviated, the support spacer cannot be accurately aligned to the black matrix, and the transmittance is lost.

[0030] In order to solve this technical problem, the utility model provides a display panel.

[0031] As Figures 1-7 shown, the display panel includes a color film substrate 1 and an array substrate 2 arranged oppositely, and there is a spacing area between the color film substrate 1 and the array substrate 2. The color film substrate 1 includes a CF substrate 11 and a plurality of color resistance blocks 12, the CF substrate 11 is provided with a plurality of color resistance blocks 12 on one side surface facing the array substrate 2, and a plurality of color resistance blocks 12 are arranged in a rectangular array on the surface of the CF substrate 11. Each color resistance block 12 is arranged in a single grid 131 of a grid area 13.

[0032] Before forming the color resist blocks, a plurality of color resist regions are defined on the CF substrate 11 by the orthogonal vertical bars 133 and horizontal bars 132, the color resist blocks 12 are formed in the color resist regions, and the plurality of horizontal bars 132 and vertical bars 133 are orthogonal to each other to form a grid region 13. The horizontal bars 132 and vertical bars 133 of the grid region 13 are not provided with light shielding objects and are light transmission regions. The array substrate 2 is provided with a plurality of black spacing bars 21 on the side surface facing the color filter substrate 1, which are arranged correspondingly to the grid region 13. It can be understood that the projection region of the black spacing bar 21 in the longitudinal direction at least coincides with the projection region of the grid region 13.

[0033] The application forms the black spacing bar 21 on the array substrate 2 corresponding to the grid region 13 on the color filter substrate 1, instead of the traditional black matrix on the color filter substrate 1. The black matrix on the color filter substrate 1 does not need to be formed by mask patterning processing, which simplifies the manufacturing process and reduces the production cost. The traditional vacuum lamination alignment needs to accurately align the spacing column with the black matrix. When the spacing column and the black matrix are misaligned in the vertical direction, the transmittance will be affected. The application only needs to use exposure mask alignment, which greatly improves the alignment accuracy of the black spacing bar 21 and the grid region 13, thereby improving the aperture ratio of the product.

[0034] The display panel is provided with a display region and a non-display region, and the non-display region is arranged around the edge of the display region. The non-display region is provided with a frame glue 3 for bonding the array substrate 2 and the color filter substrate 1 together while maintaining a certain gap to form a liquid crystal box. After the liquid crystal is filled into the liquid crystal box, it is sealed to prevent leakage and prevent external contaminants from entering.

[0035] The black spacing bar 21 can play a supporting role to maintain the gap distance between the color filter substrate 1 and the array substrate 2 in the liquid crystal box. Moreover, the black spacing bar 21 has high light shielding property and is mainly used to shield the areas that do not need to transmit light, such as TFT devices, metal traces and other non-display regions. By shielding these areas, light leakage can be prevented to ensure the contrast and clarity of the displayed image.

[0036] The black spacer 21 comprises transverse spacers 211 and vertical spacers 212 which cross each other and enclose a plurality of independent spaces 4 with the color film substrate 1 and the array substrate 2, each of the independent spaces 4 corresponds to a pixel unit region, and the liquid crystal in the independent space 4 is not affected by the intermolecular force of the liquid crystal in the adjacent independent space 4, thereby avoiding mutual interference and ensuring the display effect. The black spacer 21 is a resin spacer, i.e., the forming material is black resin material, which is formed on the array substrate 2 by a patterning process. The resin is, for example, acrylic resin, which has a low dielectric constant, so that the relative ability of the dielectric to store static energy in an electric field is low, thereby avoiding the generation of an electric field and improving the display effect.

[0037] The color resistance block 12 is a color resistance, including red color resistance, green color resistance, blue color resistance or white color resistance, or other color resistance, which has a light filtering effect. It can be understood that the display effect in the display area can meet the requirements, but the color resistance layer color arrangement and the number are not limited.

[0038] Preferably, the color film substrate 1 further comprises a planar layer 14 arranged on the side of the CF substrate 11 facing the array substrate 2, the planar layer 14 covers a plurality of color resistance blocks 12 and is formed on the CF substrate 11, so that the side of the CF substrate 11 with the color resistance blocks 12 is a flat surface, facilitating alignment and bonding with the array substrate 2.

[0039] In some embodiments of the present application, the black spacer 21 is a rectangular strip, i.e., the longitudinal section is rectangular. In other embodiments of the present application, the black spacer 21 is an inverted trapezoidal strip, i.e., the cross-sectional width of the side contacting the array substrate 2 gradually increases towards the side away from the array substrate 2, i.e., the cross-section is narrow at the bottom and wide at the top, and the longitudinal section of the black spacer 21 is an inverted trapezoidal. Since the liquid crystal molecules near the spacer are arranged in disorder, light leakage related defects are prone to occur. The design of the inverted trapezoidal spacer reduces the light leakage defect rate by shielding the wide side of the black spacer 21. Moreover, the wide side of the black spacer 21 can have a larger contact area with the color film substrate 1, thereby better supporting the color film substrate 1.

[0040] The substrate material of the color film substrate 1 and the array substrate 2 can be a glass substrate or other light-transmitting structure. The substrate can be bendable or foldable, or not bendable or foldable.

[0041] Please refer to Figure 8 The utility model provides a display module which comprises the display panel and the backlight module 5, and the backlight module 5 is arranged on the side surface of the array substrate 2 away from the color film substrate 1 to provide light source for the display panel.

[0042] In the present application, unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected or communicate with each other; it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise expressly limited. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] Obviously, the above-described embodiments are only a part of the embodiments of the present application, rather than all the embodiments, and the preferred embodiments of the present application are given in the drawings, but do not limit the patent scope of the present application. The present application can be realized in many different forms, and conversely, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
