Problems solved by technology

In terms of space configuration, on the one hand, the two FPCBs bonded to the two-dimensional capacitive sensor 1 occupy the space on both sides in the two-dimensional space; on the other hand, the two-dimensional capacitive sensor The total thickness of the device 1 is 410 μm, which also takes up space in three-dimensional space; therefore, it is not conducive to the miniaturization of mobile electronic devices; moreover, this two-dimensional capacitive sensor 1 is only bendable (bendable) Two-dimensional capacitive sensors instead of rollable two-dimensional capacitive sensors

Abstract

A thin-type soft capacitive touch component comprises a first flexible substrate with a multi-layer film and a thickness of t1, a second flexible substrate with a thickness of t2, and an optical glue layer arranged between the multi-layer film and the second flexible substrate. The optical glue layer is provided with thickness T1 for supporting weight of the first flexible substrate and the second flexible substrate, T1 / t1 is not less than 1, T1 / t2 is not less than 1, and a plurality of capacitors are defined by the multi-layer film. The total thickness of the thin-type flexible capacitive touch component is not less than 350um.

Description

technical field [0001] The invention relates to a touch element, in particular to a thin flexible capacitive touch element. Background technique [0002] Touch sensing technology is commonly used to provide a variety of input signals to an electronic device, and has been widely applied to touch screens of mobile electronic devices. For the principle of touch sensing, please refer to the technical content of the input device disclosed in US 2010 / 0230181A1. [0003] US 7,030,860B1 discloses a flexible transparent touch sensing system for electronic devices. The soft light-transmitting touch sensing system has a figure 1 , figure 2 and image 3 The two-dimensional capacitive sensor (two-dimensional capacitive sensor) 1 is shown. The two-dimensional capacitive sensor 1 comprises: an upper electrode unit 11, a lower electrode unit 12, an insulating layer 13 sandwiched between the electrode units 11, 12 and used to adhere the electrode units 11, 12 , and an optional opaque ...
