Problems solved by technology

[0003] Most existing capacitive touch screens only sense the touch position on the plane where the touch screen body is located, and it is difficult to sense the pressure applied vertically to the surface of the touch screen body
However, some touch screens can realize the pressure sensing function by adding additional pressure sensors, but they need to add additional sensors, independent pressure sensor chips and supporting processing circuits, which is costly.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 As shown, the pressure-sensitive touch screen of the present invention includes a protective cover 100 and a capacitive sensor layer 222. The capacitive sensor layer 222 is located on one side of the protective cover 100, and also includes a pressure-sensitive conductive layer 224. The pressure-sensitive conductive layer 224 is The entire conductive layer may be a conductive layer with a hollow pattern, and the capacitive sensor layer 222 is located between the protective cover 100 and the pressure-sensing conductive layer 224 .

[0020] The capacitive sensor layer 222 may have a single-layer transparent electrode layer or double-layer transparent electrode layer structure, and the capacitive sensor layer 222 may be formed on an insulating substrate attached to the protective cover 100 or directly formed on the protective cover 100 The surfac...

Abstract

The invention relates to a pressure induction touch screen, which comprises a protection cover plate and a capacitive sensor layer, wherein the capacitive sensor layer is positioned on one side of the protection cover plate. The pressure induction touch screen also comprises a pressure induction conducting layer, wherein the pressure induction conducting layer is an entire conducting layer or a conducting layer with a hollow pattern; the capacitive sensor layer is positioned between the protection cover plate and the pressure induction conducting layer; pressure induction capacitance is formed between the pressure induction conducting layer and the capacitive sensor layer; and according to the change of the pressure induction capacitance, obtaining the pressure information of a touch point. The pressure induction touch screen disclosed by the invention has a simple structure, and pressure induction is realized under a situation that no additional sensors are added. The invention also relates to a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a pressure-sensitive touch screen thereof. Background technique [0002] A touch screen is an input device with many advantages such as durability, fast response, space saving, and easy communication. It is increasingly used in smart terminals with touch functions such as mobile phones, tablet computers, and televisions. [0003] Most existing capacitive touch screens only sense the touch position on the plane where the touch screen body is located, and it is difficult to sense the pressure applied vertically to the surface of the touch screen body. However, some touch screens can realize the pressure sensing function by adding additional pressure sensors, but need to add additional sensors, independent pressure sensor chips and supporting processing circuits, and the cost of this method is relatively high. Contents of the invention [0004] Based on this...
