Problems solved by technology

[0004] However, in existing display panels using integrated touch technology (that is, judging the magnitude of the pressure by detecting the capacitance change caused by the change in the thickness of the liquid crystal cell), when pressing, the cell thickness of the liquid crystal cell changes less, therefore, resulting in The effect of pressure sensing is not ideal, and other methods need to be found to increase the amount of capacitance change when pressing

Abstract

A display panel is disclosed. The display panel can include: a first substrate; a second substrate, arranged opposite to the first substrate; a first pressure-sensitive detection electrode, arranged on the first substrate and positioned proximal to one side of the second substrate; a second pressure-sensitive detection electrode, arranged on the second substrate and positioned proximal to one side of the first substrate, and a third pressure-sensitive detection element, positioned at one side of the first substrate distant from the second substrate and arranged at intervals from the first substrate. A first capacitance is formed between the second pressure-sensitive detection electrode and the first pressure-sensitive detection electrode. A second capacitance is formed between the third pressure-sensitive detection element and the first pressure-sensitive detection electrode. When the display panel is pressed, a magnitude of pressure is determined by detecting a variation of the first capacitance and a variation of the second capacitance.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a method for driving the display panel, and a display device with the display panel. Background technique [0002] Many electronic devices use display panels with integrated touch elements for user input. When a user touches the display panel with eg a finger, the display panel sends a signal to the device. Many display panels used in various devices use capacitive pressure sensing technology to detect the amount of touch pressure. [0003] Specifically, the display panel in the prior art usually arranges a first pressure-sensitive detection electrode on the array substrate and a second pressure-sensitive detection electrode on the color filter substrate. Changes in the cell thickness of the liquid crystal cell (that is, changes in the capacitance formed by the first pressure-sensing detection electrode and the second pressure-sensing detection electro...
