Problems solved by technology

However, when exposed to ultraviolet light, the liquid crystal material will be decomposed, and charged particles will be generated to contaminate the liquid crystal material.
The other is heat-cured frame sealant, but heat-cured frame sealant takes a long time and the efficiency is too low

Embodiment approach

[0036] In the present invention, there is no special limitation on the ratio of various components in the sealant composition. As a preferred embodiment of the present invention, each component of the sealant composition has the following mass ratio :

[0037] Frame sealant 99.5% to 95%;

[0038] Microspheres 0.5% to 5%.

[0039] When the two components in the frame sealant composition reach the above-mentioned ratio, it can not only ensure that the frame sealant is cured quickly, but also ensure that the two substrates set on the box can be fixed after the frame sealant is cured. stick together firmly.

[0040] In the present invention, there is no special requirement on the specific components of the frame sealant, for example, the frame sealant includes a high molecular weight epoxy resin and a polyamine crosslinking agent. This epoxy resin does not include groups with photochemical properties. Wherein, the molecular weight of the epoxy resin is between 2000 and 20000. ...

Abstract

The invention provides a frame-sealing glue composition which comprises a frame-sealing glue and micro-spheres scattered in the frame-sealing glue, wherein each of the micro-spheres comprises a closed first shell and a closed second shell; the second shell is located in the first shell; a cavity exists between the first shell and the second shell; a first matter is packaged in the cavity between the first shell and the second shell; a second matter is packaged in the second shell; when the pressure borne by the first shell and the second shell exceeds a preset pressure, the first shell and the second shell break, so as to cause the first matter to be in contact with the second matter; and the first matter reacts with the second matter by contacting, so as to release the heat for solidifying the frame-sealing glue. The invention also provides an opposite assembling method and a display panel. When the frame-sealing glue provided by the invention is used for bonding two base plates arranged for opposite assembling, no ultraviolet irradiation is required.

Description

technical field [0001] The present invention relates to the field of manufacturing display devices, in particular to a frame sealing compound, a box matching method using the frame sealing compound composition and a display panel formed by the box matching method. Background technique [0002] The liquid crystal display panel includes an array substrate, a box-mounted substrate arranged in a box-to-box with the array substrate, and a sealant for bonding the array substrate and the box-to-box substrate. The liquid crystal material is encapsulated between the array substrate and the cell substrate. [0003] In the prior art, there are two ways to cure the frame sealant, one is the UV-cured frame sealant. When curing the frame sealant, it needs to be irradiated with ultraviolet light. However, the irradiation of ultraviolet light will cause the decomposition of the liquid crystal material at the same time, and produce charged particles to contaminate the liquid crystal materi...
