Side shading glue and borderless display device

Abstract

The invention provides side edge shading glue and a no-border display device. The side edge shading glue comprises oligomer containing polymerizable groups, reactive monomers, photoinitiator, black dye, carbon black, graphene and additives. An adopted resin system composed of the oligomer containing the polymerizable groups, the reactive monomers and the photoinitiator has a high curing reaction speed under UV irradiation; by adding the carbon block for increasing black, the side edge shading glue has a high OD value, the color of the carbon black is fixed, and the situation that color fading is caused because of long time, and consequently insufficient shading is caused is avoided; a method that a dispersion agent is adopted for dispersing the carbon black and a polymer cross-linked network to fix the carbon black makes the side edge shading glue free of the conditions of precipitation and uneven dispersion of the carbon black; and in addition, by adding the graphene, the flexibility and the heat conduction performance of the side edge shading glue can be improved, and further, static electricity on the surface of a display panel can also be removed by means of the heat conduction performance of the graphene.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a side-shading glue and a borderless display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is...

Problems solved by technology

At present, this type of side shading adhesive produced in the industry mainly uses dyes for blackening, but due to the characteristics of dyes, it is difficult for this type of side shading adhesive to have a high OD value at a thinner thickness, and after years of exposure to Under natural light or other long-short-wave UV environments, the molecular structure of the dyes in the side shading glue is prone to damage, causing problems such as fading of the shading glue and insufficient shading of the display.
