Embodiment 1

[0030] This embodiment provides a touch substrate, including a substrate, and a pressure touch sensor disposed on the substrate. The pressure touch sensor includes a first electrode, a sensing layer, and a second electrode. Along the direction away from the substrate, the first The electrode, the sensing layer and the second electrode are arranged in sequence, the sensing layer is made of opaque conductive material, and the resistance of the sensing layer changes under pressure.

[0031] The resistance of the sensing layer of the pressure touch sensor changes under the action of pressure. By sensing the variation of the resistance, the pressure and strain can be sensed, thereby sensing the position of the pressure touch, and finally realizing the pressure touch. Wherein, the sensing layer can convert the variation of its resistance into a voltage signal output, and according to the output voltage signal, the pressure touch position can be determined.

[0032] The touch substra...

Embodiment 2

[0034] This embodiment provides a touch substrate, such as figure 1 and figure 2 As shown, it includes a substrate 1, and also includes a pressure touch sensor 2 disposed on the substrate 1. The pressure touch sensor 2 includes a first electrode 21, a sensing layer 22, and a second electrode 23. Along the direction away from the substrate 1, the second An electrode 21 , a sensing layer 22 and a second electrode 23 are arranged in sequence. The sensing layer 22 is made of an opaque conductive material, and the resistance of the sensing layer 22 changes under pressure.

[0035] By adopting the sensing layer 22 of opaque conductive material, while realizing the pressure touch, it can also absorb at least part of the external ambient light irradiated on the touch substrate, reducing or preventing the irradiation of the touch substrate. The reflection of the external ambient light on the touch substrate on the touch substrate can not only realize the pressure touch of the display...

Embodiment 3

[0045] This embodiment provides a display substrate, such as image 3 As shown, it includes the substrate 5 and the organic electroluminescent element 6 arranged on the substrate 5, and also includes the touch substrate 7 in Embodiment 1 or 2, and the touch substrate 7 is arranged on the organic electroluminescent element 6 away from the substrate 5 One side, and the base 1 of the touch substrate 7 forms a package for the organic electroluminescent element 6 .

[0046] By adopting the touch substrate 7 in Embodiment 1 or 2, the display substrate can realize pressure touch, and because the sensing layer 22 of the opaque conductive material in the touch substrate 7 is provided, the display substrate does not need to be provided The polarizer can also reduce the influence of the reflection of external ambient light on the display, and at the same time reduce the thickness of the display substrate.

[0047] In this embodiment, there are multiple organic electroluminescent element...

Abstract

The invention provides a touch substrate, a display substrate and a display panel. The touch substrate includes a base, a pressure touch sensor disposed on the base, the pressure touch sensor includes a first electrode, a sensing layer and a second electrode, along the direction away from the base, the first electrode, the sensing layer and the second electrode The electrodes are arranged in sequence, and the sensing layer is made of an opaque conductive material, and the resistance of the sensing layer changes under pressure. While realizing pressure touch, the touch substrate can also absorb at least part of the external ambient light irradiated on it, reduce or prevent the reflection of the external ambient light irradiated on it on the touch substrate, and can realize The pressure touch of the display panel using the touch substrate can not only reduce the thickness of the display panel using the touch substrate, but also reduce or avoid the use of the touch substrate. The display panel of the touch substrate is affected by the reflection of external ambient light when displaying.
