Problems solved by technology

However, when the flexible substrate is in a flexed state, the thin film material is under stress, which leads to electrical failure of the sensing element
For flexible touch display devices, these variations will lead to abnormal touch detection, thereby reducing the sensitivity of the sensing
In addition, since the flexible substrate used in the flexible display has high moisture and oxygen permeability and is easily affected by high temperature treatment, it cannot prevent moisture and oxygen from penetrating the flexible substrate, affecting the service life of the flexible display

Abstract

The invention provides a touch film structure, which includes a touch element layer, a barrier layer and a flexible substrate. The touch element layer has opposite first surface and second surface. The barrier layer is formed on the first surface or the second surface or integrated with the touch element layer to form a multifunctional film layer. The flexible substrate is stacked with the touch element layer, barrier layer or multifunctional film layer.

Description

technical field [0001] The invention relates to a touch film structure, in particular to a touch film structure for a flexible display. Background technique [0002] Flexible displays have the advantages of light weight, portability, and flexibility, and are the focus of next-generation development for various panel manufacturers. Among the mass production problems encountered by flexible displays, deflection testing is a very important part. Under the deflection test, known flexible displays often fail because the control components cannot bear the stress. [0003] In addition, in terms of consumer electronic products, touch panels have been widely used in portable electronic products. For users, the flexible and bendable soft touch display device will become one of the key technologies of flexible flexible electronic products. However, when the flexible substrate is in a flexed state, the thin film material is under stress, which leads to electrical failure of the sensi...
