Embodiment 1

[0035] Such as figure 1 As shown, the embodiment of the present invention provides a flexible touch substrate, the flexible touch substrate includes a flexible substrate and a touch sensing unit, the touch sensing unit includes two layers of sensing layers, wherein at least one sensing layer is located on the flexible inside the substrate.

[0036] Specifically, the two sensing layers are respectively a first sensing layer 22 and a second sensing layer 23, and both the first sensing layer 22 and the second sensing layer 23 are located inside the flexible substrate 21, wherein, In this embodiment, the first sensing layer 22 and the second sensing layer 23 are located at different levels inside the flexible substrate 21 .

[0037] The manufacturing method of the flexible touch substrate in this embodiment is as follows:

[0038] Such as figure 2 As shown, firstly, a layer of PI liquid is coated on a carrier plate (such as glass, quartz, plastic), then dried and prepared on t...

Embodiment 2

[0041] Such as image 3 As shown, the difference between this embodiment and the first embodiment is that the first sensing layer 22 and the second sensing layer 23 in this embodiment are located on the same layer inside the flexible substrate 21 .

[0042] The manufacturing method of the flexible touch substrate in this embodiment is as follows:

[0043] First, coat a layer of PI liquid on the glass carrier, then dry it and prepare the first sensing layer and the second sensing layer of touch sensing on it, the first sensing layer and the second sensing layer are located on the In the same layer, the first sensing layer is the metal guiding layer in the first direction, and the second sensing layer is the metal guiding layer in the second direction, wherein the direction of the metal guiding layer in the first direction and the metal guiding layer in the second direction are mutually crossing, Then apply PI liquid, dry and sinter to obtain the structure of the touch sensing ...

Embodiment 3

[0046] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that one of the two sensing layers in this embodiment is located inside the flexible substrate, and the other sensing layer is located on the outer surface of the flexible substrate. superior. For example, the first sensing layer 22 is located inside the flexible substrate, while the second sensing layer 23 is located on the upper surface of the flexible substrate.

[0047] The manufacturing method of the flexible touch substrate in this embodiment is as follows:

[0048] First, coat a layer of PI liquid on the glass carrier, then dry it and prepare the first sensing layer in the touch sensing unit on it, then coat the PI liquid, dry and sinter, and then put on the second layer of PI film The second sensing layer is then prepared, and finally, the flexible substrate is peeled off from the glass carrier to obtain a structure in which the touch sensing part is inside the flexible subs...

Abstract

The invention relates to the technical field of displaying, in particular to a flexible touch substrate and a touch display device. The flexible touch substrate comprises a flexible substrate and a touch sensing unit, wherein the touch sensing unit comprises two sensing layers, and at least one sensing layer is located inside the flexible substrate. In the flexible touch substrate and the touch display device, the touch sensing unit is manufactured in the inside of the flexible substrate, the high-sensitivity touch effect can be achieved, and the technical problems of thick touch screen thickness, low sensitivity and difficult in-cell touch technology are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible touch substrate and a touch display device. Background technique [0002] With the development of display technology, electronic communication equipment has also undergone earth-shaking changes, and touch experience has truly entered and changed people's lives. Electronic products such as mobile phones, tablet computers, and even televisions all involve touch technology. [0003] According to the different installation and touch methods, it is generally divided into four types: resistive, capacitive, sonic and infrared. Its application methods are generally divided into add-on, OGS, on-cell, in-cell and other methods. Among them, the in-cell method has the advantage of being lighter and thinner because it can reduce a layer of substrate, and because the reduction of the substrate reduces the factors that reduce the display contrast such as light refraction and refle...
