Problems solved by technology

[0003] However, during the use of the existing touch device, the thermal expansion coefficient of the gap sealant in the touch device is quite different from that of the optical adhesive layer and the touch sensing layer. The relative movement of the flexible circuit board relative to the edge of the touch sensing layer can easily cause the contact position between the flexible circuit board and the touch sensor to break, which seriously affects the touch performance of the touch device

Abstract

The invention provides a touch device which comprises a cover plate, an optical adhesive layer, a touch sensing layer, a flexible circuit board and a gap sealant, the optical adhesive layer and the touch sensing layer are sequentially stacked on the cover plate, the flexible circuit board and the touch sensing layer are located on the same side of the cover plate, the flexible circuit board comprises a first section and a second section, and the gap sealant is located between the first section and the second section. Wherein the first section is located on the surface, deviating from the optical adhesive layer, of the touch sensing layer, the second section extends along one end of the first section, extends out of the edge of the touch sensing layer and is opposite to the cover plate, and the gap sealant is connected between the second section and the cover plate. And the thermal expansion coefficient of the gap sealant is between the thermal expansion coefficient of the optical adhesive layer and the thermal expansion coefficient of the touch sensing layer. The invention further provides electronic equipment comprising the touch device.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch device and electronic equipment. Background technique [0002] As an inductive device capable of receiving touch input signals, a touch panel has gradually been widely used in general consumer electronic products such as mobile phones and tablet computers, so as to allow operators to perform interactive input operations. [0003] However, during the use of the existing touch device, the thermal expansion coefficient of the gap sealant in the touch device is quite different from that of the optical adhesive layer and the touch sensing layer. Relative movement of the flexible circuit board relative to the edge of the touch sensing layer may easily cause breakage at the contact position between the flexible circuit board and the touch sensor, which seriously affects the touch performance of the touch device. Contents of the invention [0004] The purpose of the present app...
