Problems solved by technology

However, when the glass cover is stressed or cracked, a lateral tension will be generated. Since the protective layer is tough, this transverse tension may not crack the tough protective layer. However, the thickness of the touch function layer is very thin, and generally Hard and brittle material, so the protective layer is not cracked but the touch function layer is broken due to lateral tension
Or when the cracks formed by the breakage of the glass cover are large, both the protective layer and the touch function layer may be broken due to lateral tension

Abstract

The invention provides a touch device which comprises a light-permeable cover plate, a flexible transparent layer, a touch function layer and a hard transparent layer. The flexible transparent layer is located on the surface of the light-permeable cover plate, the elasticity modulus of the flexible transparent layer is smaller than that of the light-permeable cover plate, the hard transparent layer and the touch function layer are located on the side, opposite to the light-permeable cover plate, of the flexile transparent layer, and the elasticity modulus of the hard transparent layer is larger than that of the flexible transparent layer. When the glass cover plate of the touch device is impacted, influences caused on the touch function layer can be reduced through the combined action of the hard transparent layer and the flexible transparent layer.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch device. Background technique [0002] In the conventional touch device with TOL (touch on lens) or OGS (one glass solution) structure, the touch function layer (such as ITO layer) is directly formed on the cover glass. Usually, the touch function layer is very thin and highly brittle. When the glass cover is broken by an external force in the vertical direction, the touch function layer on the glass cover will also break, causing the touch device to malfunction, such as The touch function fails, causing inconvenience to the user. [0003] In addition, in some designs, a tough protective layer is added between the glass cover plate and the touch function layer to improve the impact capability of the touch device. With such a design, when the glass cover is broken by an external force in the vertical direction, the touch function layer may not be damaged by the ext...
