Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] image 3 It is a schematic diagram of a frame sealant provided in an embodiment of the present invention. The frame sealant 2 includes epoxy resin, acrylate, and a scatterer 2a.

[0027] Preferably, the scatterer 2a is a nanoscale scatterer.

[0028] Specifically, the scatterer 2a includes: a blend obtained by blending polymer matrix materials and scatterer particles, a copolymer obtained by copolymerizing polymer units with different refractive indices, nanoparticles coated with a metal layer on the surface, metal One or more of nanoparticles.

[0029] The scatterer 2a can be a blend obtained by blending the polymer matrix material and the scatterer particles, f...

Abstract

The invention relates to the display field, in particular to a seal agent and a display device. The seal agent comprises an epoxy resin, acrylic ester and scatterers. According to the seal agent and the display device, the scatterers are added in the seal agent, when ultraviolet light radiates the seal agent, the scatterers in the seal agent scatter the incident ultraviolet light irregularly in all directions, the scattered and incident ultraviolet light radiates on the surfaces of scatterers in other positions, and further scattering occurs, so that areas which cannot be directly radiated by the ultraviolet light in the seal agent can be radiated by the ultraviolet light, and the curing degree of the seal agent is increased.

Description

technical field [0001] The invention relates to the display field, in particular to a frame sealant and a display device. Background technique [0002] In the production of thin-film transistor liquid crystal display (TFT-LCD), it is necessary to drip liquid crystal and sealant on the array substrate or color film substrate, then align the two substrates, and then cure the sealant. Among them, the sealant The function is to bond the array substrate and the color filter substrate, and protect the liquid crystal in the middle from the influence of external air and water. At present, the curing process of the sealant is mainly divided into two steps: first, it is cured by ultraviolet radiation, and then it is further cured by heating to achieve the purpose of complete curing. Most of the peripheral designs of existing LCD panels are as attached figure 1 As shown, the width of the sealant 2' is relatively large, and the distribution of metal wiring on the array substrate 1' ab...
