Abstract

The invention provides a film type touch panel structure. The film type touch panel structure comprises a sensing film, protective glass and an optical adhesive layer between the sensing film and the protective glass, wherein the sensing film is attached to the bottom surface of the protective glass by means of the optical adhesive layer; any layer in the optical adhesive layer or the sensing film can isolate ultraviolet rays of which the wavelengths are below 400 nanometers. According to the film type touch panel structure provided by the invention, the optical adhesive layer capable of isolating the ultraviolet rays is adopted, so that the problems of deterioration, yellowing, stripping and damage to a hard coating of the sensing film under the influence of the ultraviolet rays are effectively solved, the durability under an extreme condition is enhanced, UV (Ultraviolet) resistance is realized, and ultraviolet rays of which the wavelengths are below 400 nanometers can be isolated.

Description

technical field [0001] The present invention relates to the technical field of touch panels, in particular to an improved thin-film touch panel structure. Background technique [0002] It is known that thin-film touch panels can be divided into G / F / F stacking of double-layer sensing film and G / F stacking of single-layer sensing film in terms of structure. The sensing film of the tin (ITO) transparent electrode is bonded to the glass with optical adhesive (OCA). [0003] Due to the wide application of touch panels and increasingly stringent specifications, it is quite difficult to meet the specifications of various products with known material combinations, for example, the reliability test of ultraviolet (UV) resistance of automotive panels. After a long time of UV irradiation, the sensing film often bulges and produces air bubbles, resulting in poor appearance of the touch panel. [0004] It can be seen that the technical field still needs an improved thin-film touch pane...
