Problems solved by technology

[0004] Therefore, in the prior art, the electrical signal when the liquid crystal flips may interfere with the signal of the touch sensing layer, and when the pressure touch device is dropped, the outer frame is likely to be deformed, resulting in a gap between the touch sensing layer and the touch reference layer. The uneven gap between them will cause the pressure touch to fail, resulting in a decrease in the precision of the pressure touch

Abstract

The invention discloses a pressure touch device and a display device, which are used for improving the pressure touch precision of the pressure touch device in the situation of avoiding the interference of an electric signal. The pressure touch device comprises an opposite substrate and an array substrate which are arranged in an oppositely closing manner, a backlight source which is positioned on the side, far away from the opposite substrate, of the array substrate, a backlight shell which is used for supporting the backlight source, a first electrode layer which is arranged on the side, far away from the opposite substrate, of the array substrate and is connected with a ground wire, a second electrode layer which is arranged between the first electrode layer and the backlight shell, and a touch detecting chip which is electrically connected with the second electrode layer, wherein the first electrode layer and the second electrode layer form a touch structure with a pressure touch function.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a pressure touch device and a display device. Background technique [0002] At present, touch panels have been widely used in portable terminals such as mobile phones, tablet computers (PADs), notebook computers, and other display devices. [0003] see figure 1 , which is the structure of the pressure touch device in the prior art, including the opposite substrate 01 and the array substrate 02 arranged opposite to the box, the backlight 03 located on the side of the array substrate away from the opposite substrate, and the backlight housing 04 supporting the backlight 03 , the touch sensing layer 1 located under the backlight shell, the pressure touch device also includes an outer frame 2 surrounding the opposite substrate, the array substrate, the backlight source, the backlight shell and the touch sensing layer, wherein the outer frame 2 is connected to the ground wire ...
