AI Technical Summary

Problems solved by technology

[0006] However, liquid optical adhesives generally have the disadvantage of easy overflow when used. When the overflow glue penetrates into the bonding component, it will cause damage to the function of the bonding component, so its fluidity must be properly adjusted to avoid the problem of glue overflow

Abstract

The invention provides a light curable frame glue material composition comprising a) (methyl) acrylics oligomer comprising one or more functional groups, b) light initiator, and c) plasticizer with high refractive index. The viscosity value of the frame glue material composition is not less than 8000 cps. The light curable frame glue material composition has both good transmission of light and high refractive index and appropriate liquidity and softness, is easy to cooperate with liquid optical glue (water glue) in order to be used for coating and pasting correlative touch control panels, and does not generate an interface at the junction of the frame glue and the water glue. The light curable frame glue material composition can be used in optical products and simplifies and improves a conventional procedure.

Description

technical field [0001] The present invention relates to a light-curable sealant material composition, in particular to a light-curable sealant material composition that can be used for laminating a display and a touch panel. Background technique [0002] With the rapid development of the information industry, electronic products such as mobile phones, personal digital assistants, and notebook computers have become necessities in people's daily life. In these electronic products, the display is an indispensable human-machine communication interface. How to provide products that are lighter, thinner and have better visual effects has always been one of the main R&D goals of the industry. In recent years, the industry has integrated the touch panel (TouchPanel) with the display, and applied it to various electronic products, allowing users to directly click on the panel to perform various operations, providing a more convenient and humanized operation mode.
