Problems solved by technology

[0003] Since the wires are often made of metal, especially when the metal wires are opaque, multiple light blocking parts 5 are formed in the peripheral area. When the incident light 6 for curing is incident from the array substrate side, it is not blocked by multiple light blocking parts. The frame sealant 3 covered by the portion 5 is completely cured to form a fully cured portion 31; the frame sealant 3 corresponding to the plurality of light-shielding portions 5 cannot be fully cured if it is blocked by the plurality of light-shielding portions 5, such as figure 1 As shown, an incompletely cured portion 31 is formed. This incompletely cured sealant will contaminate the surrounding liquid crystals, resulting in problems such as peripheral defects and line afterimages.
Especially, this problem is more serious in narrow bezel products

Embodiment 1

[0031] like figure 2 As shown, this embodiment provides a frame sealant composition 33, including a frame sealant and a light-wave conversion material 4 uniformly dispersed in the frame sealant, and the light-wave conversion material 4 can convert incident light into the frame sealant The incident light 6 is converted into curing light 7 for curing the sealant.

[0032] The frame sealant composition 33 provided by the present invention includes the light wave conversion material 4 in the frame sealant composition 33, and the light wave conversion material 4 can convert the incident light 6 into curing light 7 for curing the frame sealant, The frame sealant that is not irradiated by the incident light 6 can also be cured by the light converted by the light wave conversion material 4, thereby avoiding liquid crystal pollution, peripheral defects, and line afterimages caused by incomplete curing of the frame sealant during the pre-curing process. question.

Embodiment 2

[0055] This embodiment provides a method for manufacturing a display panel, including the following steps:

[0056] The step of preparing the sealant composition;

[0057] A step of coating the sealant on the non-display area around the array substrate or on the color filter substrate corresponding to the non-display area around the array substrate;

[0058] The step of curing is carried out under the irradiation of incident light 6 .

[0059] Specifically, such as figure 2 as shown,

[0060] S1 Steps for preparing the frame sealant composition

[0061] The light conversion material and the sealant are uniformly mixed to form a sealant composition 33 .

[0062] Mix the frame sealant and light conversion material at an appropriate mass percentage, for example, 0.5-5%. The above frame sealant and light conversion material can be selected according to specific application scenarios. For example, if the frame sealant includes UV-cured resin, and when the incident light 6 is ...

Embodiment 3

[0072] This embodiment provides a display panel, which is manufactured by combining and curing the above-mentioned frame sealant.

Abstract

The invention provides a frame sealing glue combination, a display panel, a preparation method of the display panel and a display device in order to solve the problems that because incident light cannot irradiate frame sealing glue of the portion, shielded by metal wires, of a display panel in the prior art, the frame sealing glue is not totally cured, the frame sealing glue which is not totally cured will contaminate liquid crystals on the periphery of the frame sealing glue which is not totally cured, the periphery is bad, and line residual images are caused. Due to the fact that the frame sealing glue combination comprises optical wave conversion materials which can convert incident light into curing light making the frame sealing glue cured, the frame sealing glue which is not irradiated by the incident light can also be cured by the light obtained after conversion of the optical wave conversion materials, and therefore the problems that in the pre-curing process, because the frame sealing glue is not totally cured, liquid crystal contamination is caused, the periphery is bad, and line residual images are caused are avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a frame sealing compound, a display panel, a preparation method thereof, and a display device. Background technique [0002] like figure 1 As shown, the existing display panel includes an array substrate 1 and a color filter substrate 2. In the box-fitting process, it is necessary to bond the array substrate 1 and the color filter substrate 2 after box-fitting. Generally, a frame sealant 3 is used. Curing and bonding are performed on the peripheral non-display area of ​​the array substrate 1 (where a large number of signal traces are arranged). [0003] Since the wires are often made of metal, especially when the metal wires are opaque, multiple light blocking parts 5 are formed in the peripheral area. When the incident light 6 for curing is incident from the array substrate side, it is not blocked by multiple light blocking parts. The frame sealant 3 covered by the po...
