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

The invention discloses a display panel and a driving method thereof, and a display unit with the display panel. The display panel includes: a first substrate; a second substrate arranged opposite the first substrate; a first pressure-sensitive detection electrode arranged on the first substrate on one side close to the second substrate; a second pressure-sensitive detection electrode arranged on the second substrate on one side close to the first substrate, with a first capacitance formed between the second pressure-sensitive detection electrode and the first pressure-sensitive detection electrode; a third pressure-sensitive detection electrode positioned on one side of the first substrate far away from the second substrate and spaced mutually from the first substrate, with a second capacitance formed between the third pressure-sensitive detection electrode and the first pressure-sensitive detection electrode; when the display panel takes a press, magnitude of the pressure is determined by detecting a change in the first capacitance and a change in 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...
