Abstract

The invention provides a touch sensor module for preventing cracks in the touch sensor film, which includes a touch sensor film, a scratch-resistant hardened layer, a flexible circuit board and a carrier. The anti-scratch hardening layer is connected with the touch sensing film through an optical glue layer and has a first thickness. The flexible circuit board is electrically connected with the touch sensing film through an anisotropic conductive film. The carrier is disposed on the other surface of the flexible circuit board, and the anisotropic conductive film, the flexible circuit board and the carrier have a second thickness. Wherein, the difference between the first thickness and the second thickness is less than 20 microns.

Description

technical field [0001] The technology of the present invention relates to the field of touch devices, in particular to a touch module that prevents cracks in the touch sensing film. Background technique [0002] As a simple and convenient way of human-computer interaction, touch screen has been widely used in all aspects of daily life. According to the principle of touch sensing, touch screens are mainly divided into resistive, capacitive, and surface infrared touch screens. Among them, the capacitive touch screen has the advantages of simple structure, high light transmittance, friction resistance, resistance to environmental humidity and temperature changes, long service life and multi-touch, so it has gradually become the mainstream of the touch screen market. [0003] With the continuous development of technology, the thickness of the capacitive touch screen is required to be thinner and thinner to meet the thinner and lighter requirements of mobile terminals. Therefor...
