Problems solved by technology

The change in capacitance is related to the change in the cell thickness of the display screen, but at present, the change in cell thickness in the field of liquid crystal display is small, and the driving circuit IC may not be able to detect and sense the distance of the small change
[0004] Due to the characteristics of the LCD screen itself and the limitations of the liquid crystal material, the current pressure touch technology cannot play a good role on the LCD screen

Abstract

The invention provides a pressure touch control display panel, which comprises a first base plate, a second base plate, a liquid crystal, a separation body, a first electrode, a second electrode and a separation object, wherein the liquid crystal is arranged between the first base plate and the second base plate; the separation body is arranged between the first base plate and the second base plate, and is positioned on one side, facing the second base plate, of the first base plate; the first electrode is arranged on the surface, facing the second base plate, of the first base plate and the separation body; the second electrode is arranged on the surface, facing the first base plate, of the second base plate; the first electrode and the second electrode form a first capacitor through the liquid crystal; the separation object is arranged between the first electrode and the second electrode on the separation body; a second capacitor is formed between the first electrode and the second electrode through the separation object. By installing the separation object on the base plate and adding the second capacitor, the pressure sensing capability of the display panel is improved; the pressure application range is expanded to a certain degree; the requirements on IC (integrated circuit) processing are reduced.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a pressure touch display panel, a display device and a preparation method. Background technique [0002] At present, touch display technology is becoming more and more popular in the display field, and mobile terminal products are gradually moving from the past plug-in touch control to the built-in touch control. During the development of touch technology, consumers began to hope to experience more touch feedback and interaction, so pressure touch technology began to develop. [0003] In the existing pressure touch technology, electrodes are added on the side of the color filter substrate and form capacitance with the touch electrodes on the array substrate side to sense changes in external pressure. The variation of the capacitance is related to the variation of the cell thickness of the display screen, but at present, the variation of the cell thickness in the li...
