Embodiment 1

[0037] This embodiment provides a display panel, the display panel has a stable plate gap, and the bonding strength between the substrates is strong, the specific structure is as follows figure 1 As shown, it includes a first base plate 1 and a second base plate 2 that are arranged in opposite positions. The first base plate has a plurality of pillar pads 3 on the side facing the second base plate, and the second base plate 2 has a plurality of support pads 3 on the side facing the first base plate 1. Adhesive blocks 4 are provided on the side and corresponding to the area of ​​each pillar pad 3, and the two ends of the adhesive block 4 are respectively in contact with the pillar pads and the second substrate for bonding the pillar pads 3 and the second substrate 2 , that is, bonding the first substrate 1 and the second substrate 2 into one body. Here, the first substrate 1 and the second substrate 2 are preferably flexible substrates. The first substrate or the second substr...

Embodiment 2

[0043] This embodiment provides a display panel, such as figure 2 As shown, it has a structure similar to that of the display panel of Embodiment 1. The difference between it and Embodiment 1 is that the second substrate 2 is provided with a Groove, the bonding block 4 is arranged in the groove, so that the position of the bonding block 4 is fixed, and the contact surface between the bonding block 4 and the pillar liner 3 is guaranteed to be as large as possible, and a good bonding effect is played; During the forming process of the connecting block 4, it can also effectively prevent the material from spreading around.

[0044] Preferably, each bonding block 4 fills its corresponding groove, and the height of the bonding block 4 is equal to the depth of its corresponding groove, so that the surface of the second substrate 2 can have good flatness, and It can effectively prevent the material forming the bonding block 4 from spreading around and affect the performance of perip...

Embodiment 3

[0050] This embodiment provides a method for preparing a display panel, which specifically includes the following steps:

[0051] Step 1: forming a second substrate 2 and a first substrate 1 having a plurality of pillar pads 3 .

[0052] In this step, the second substrate 2 can be manufactured using an existing mass production process; the first substrate 1 and the pillar pad 3 are integrally formed using plastic materials or resin materials, such as Figure 3a shown. The first base plate 1 with the post pads 3 can be manufactured by rolling or embossing.

[0053] The pillar liner 3 is preferably designed in a trapezoidal shape, and may also be designed in a square or cylindrical shape. In addition, the pillar pad 3 is preferably formed in a region where light penetration is not required, for example, the pillar pad 3 is formed in a region corresponding to the black matrix.

[0054] Step 2: Form an adhesive block 4 on the second substrate 2 in a region corresponding to each...

Abstract

The invention provides a display panel, a preparation method thereof and a display device, belongs to the field of liquid crystal display technology, and can solve problems of the present display panel that spherical bushes moves between substrates, the brightness is nonuniform because of agglomeration, and the adhesive strength between substrates is little. The display panel comprises a first substrate and second substrate which are arranged in opposite, one side facing to the second substrate of the first substrate is provided with a plurality of pillar liners, and one side facing to the first substrate of the second substrate is provided with an adhesive piece at the area corresponding to each pillar liner. The substrates of the display panel provided by the invention can keep a uniform gap between substrates for a long time, the brightness can be kept uniform for a long time, and the adhesive strength between the substrates can be effectively raised.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a display panel, a preparation method thereof, and a display device. Background technique [0002] With the development of wireless mobile communication, display panels are widely used as information display devices of communication terminals. At the same time, in order to solve the problem of damage to the glass substrate caused by the machine falling when moving, the substrate material of the mobile terminal is changed from glass to plastic, thus making flexible display possible. [0003] In a typical display device, characteristics such as response speed, contrast ratio, viewing angle, and brightness uniformity are closely related to the thickness of the liquid crystal layer, that is, to the panel gap. Thus, a typical display device has spherical spacers distributed in the inter-substrate space in order to maintain a uniform inter-panel gap. [000...
