Adhesive glass with high strength

Abstract

The invention discloses adhesive glass with high strength. The adhesive glass comprises two glass substrates with different thicknesses and an optical adhesive layer arranged between the two glass substrates, the two glass substrates with different thicknesses are bonded through the optical adhesive layer to form the bonded glass; when a falling ball test is carried out, the two bonded glass substrates can pass the falling ball test without being broken, and compared with a single plate body with the same thickness, the adhesive glass has better impact resistance and is suitable for manufacturing an industrial touch display.

Description

technical field [0001] A bonded glass, especially a high-strength bonded glass, can be used as a touch sensing glass or a protective glass, and is especially suitable for making an industrial touch display. Background technique [0002] In display devices such as mobile terminals, tablets, touch panels, and personal digital assistants (PDAs, Personal Digital Assistants), chemically strengthened tempered glass is generally used. This tempered glass has a structure in which a surface strengthening layer (chemically strengthening layer) is provided on the surface side of the glass base material. It is one of the essential components of the above-mentioned display device and must have excellent impact resistance and hardness. [0003] At present, the thickness of the glass substrate is between 0.2mm and 5mm. From the website of Taiwan Glass Industry Co., Ltd., we can know that the mass production size of the thin glass is 1.8mm, 1.6mm, 1.3mm, 1.1mm, 0.7mm , 0.55mm, 0.4mm, and 0...

AI Technical Summary

Problems solved by technology

[0004] The touch panels used in industrial computers are thicker, and the thickness is usually between 2.5mm and 2.8mm. However, consumer electronics products are all about thinness, so glass manufacturers mainly make thinner glass to cope Market demand, so the mainstream specifications of glass substrates are thin glass, that is, the thickness between 0.4mm and 1.8mm. Therefore, although glass suppliers can produce glass with a thickness of 2.5mm and 2.8mm, compared with using For thin glass used in consumer electronics products, thicker glass is not the mainstream specification and can only be manufactured in small quantities. Therefore, in the current industry situation, glass manufacturers must meet with a certain period of time in order to produce thicker glass substrates. Raw material suppliers can only make thicker glass substrates and supply them to glass manufacturers when they obtain appropriate glass materials. It will take at least half a year for the glass substrate to be made into a touch panel through a series of glass processing procedures. Therefore, if the touch panel factory uses up the number of sheets ordered by the glass manufacturer in less than half a year, It also takes half a year to receive the glass substrates for touch panels used in industrial computers. Although you can order a large number of glass substrates with the required thickness, it will increase the inventory cost, and the glass substrates will be placed for a long time. Yield rate will also be affected. The biggest impact is still that the required number of touch panels cannot be produced immediately according to the actual demand, which is not conducive to the overall development of the industry and reduces the competitiveness of the industry
