Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flexible touch screens, in particular to a friction-resistant flexible touch screen. Background Art
[0002] Most flexible touch screens are plated with a conductive layer on a transparent substrate such as PET, PI, etc. to achieve circuit conduction and transparent conductive effect, and then assembled with a display module to obtain a visual touch panel.
[0003] However, in the wet etching process, the optical substrate is usually not scratch-resistant, and a protective film must be applied to the front end, which is then transferred by rollers to prevent the substrate from being scratched and then torn off when the back end is attached. This production process can meet the needs of most terminal applications, but the touch module and the display module are prone to friction marks after long-term friction during use, which makes the display look ugly. Utility Model Content
[0004] The purpose of the utility model is to provide a friction-resistant flexible touch screen to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a friction-resistant flexible touch screen, comprising a flexible touch screen, wherein the flexible touch screen comprises a flexible touch screen substrate, an optical glue is arranged at the lower part of the flexible touch screen substrate, a nano silver film is arranged at the bottom of the optical glue, a front explosion-proof film is arranged at the bottom of the nano silver film, a rear explosion-proof film is arranged at the upper part of the flexible touch screen substrate, and an ink layer is arranged at the lower part of the flexible touch screen substrate.
[0006] Preferably, the nanosilver film is composed of nanosilver wires.
[0007] Preferably, a flexible circuit board is provided at one end of the nano silver wire.
[0008] Preferably, the flexible touch screen substrate is a substrate with a hardness of 4H or more, and the rear explosion-proof film and the flexible touch screen substrate are bonded together by optical glue.
[0009] Preferably, the peeling force of the front-end explosion-proof film and the rear-end explosion-proof film are both greater than 1800g.
[0010] Preferably, the yellowing resistance values of the front-end explosion-proof membrane and the rear-end explosion-proof membrane are less than 0.2.
[0011] Preferably, the rear explosion-proof film is directly bonded to the display module.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model uses a substrate with a hardness of 4H or above, removes the protective film layer at the front end, and replaces it with an explosion-proof film. The explosion-proof film is firmly bonded to the substrate and is scratch-resistant. It does not need to be torn off when bonding at the rear end, and can be directly bonded to the display module without any impact. Long-term friction can reduce the occurrence of friction marks, and it is relatively beautiful when displayed. BRIEF DESCRIPTION OF THE DRAWINGS
