Detachable surface glass type touch screen and preparation process

Abstract

The invention discloses a detachable surface glass type touch screen. The detachable surface glass type touch screen comprises surface glass, a PET (polyethylene terephthalate) panel, cover plate ink and a sensor, wherein the surface glass and the PET panel are glued together through an AB adhesive, the surface glass is bonded with an OCA surface of the AB adhesive, the cover plate ink with a silk-screen printing effect is printed on the PET panel in a silk-screen printing manner, the non-ink surface of the PET panel is attached to a silicone surface of the AB adhesive, and the ink surface of the PET panel is attached to the OCA surface of a functional chip of the sensor. The problem that the whole touch screen and even a display screen are required to be replaced after the surface glass of a conventional touch screen is broken is solved, that is, all that is required is to change for surface tempered glass after the surface glass of the touch screen is accidentally broken by a user.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a detachable surface glass type touch screen and a preparation method. Background technique [0002] The touch industry includes the touch screen industry, touch module industry, and the rapidly rising fingerprint recognition industry in recent years. All kinds of products are the result of further processing based on touch screen production. The touch screen originated in the United States in the 1960s and was developed by the US military for military use. After more than 50 years of development, touch screens have been widely used now, but they really entered a mature period after 2000. In 2007, the first generation of iPhone opened the prelude to the full touch era of smart phones. In 2010, with the explosive growth of smart phones and the emergence of tablet computers, the core position of touch operations, especially capacitive touch operations, on smart mobile terminals was c...

Problems solved by technology

[0004] Among them, human-machine carriers such as smartphones, tablet computers, and vehicle-mounted control systems almost all use capacitive touch screens. In the field of capacitive touch screens, the surface covers are almost all glass substrates. There have been situations where the glass was broken due to falling, extrusion, etc. When users encounter this situation, they generally need to replace the touch screen, display screen, and the front case of the machine together. The price is very expensive, such as Apple mobile phone replacement. The screen needs more than 1,000 yuan, and OPPO mobile phone needs more than 500 yuan to replace the screen, which also causes a huge waste of resources; the cheaper way is to replace the touch screen separately, but the display and touch screen need to be separated, and ordinary users cannot complete the replacement by themselves.
