A display panel, electronic device and driving method

Abstract

The invention discloses a display panel, an electronic device and a drive method. The display panel includes a liquid crystal layer, a color film substrate, an array substrate and pressure detection electrodes. The color film substrate is located on one side of the liquid crystal layer and includes a first substrate and a first electrode layer arranged on the first substrate, and the first electrode layer includes a plurality of first electrodes; the array substrate is located on the other side of the liquid crystal layer and includes a second substrate and a common electrode layer arranged on the second substrate, and the common electrode layer includes a plurality of second electrodes; the second electrodes are provided with a plurality of hollow areas; the pressure detection electrodes are arranged in the hollow areas and corresponds to the hollow areas one by one; in the touch control detection period, the first electrodes and the second electrodes are used for conducting touch detection; in the pressure detection period, the first electrodes and the pressure detection electrodes are used for pressure detection; the first electrodes are strip electrodes composed of metal wire grids. The pressure detection is achieved by reusing the common electrode layer, the cost is reduced, and the thickness is reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, electronic equipment and a driving method. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display panels are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and becomes an important part of the life of police officers. Indispensable and important tool. [0003] Existing display panels are generally touch display panels, which only have the function of touch position detection and do not have the function of pressure detection. In order to realize the pressure detection function, in the prior art, a pressure detection sensor or two layers of pressure detection electrodes are generally added to the display panel, and the pressure is detected through the change of the pressure detection capacitance of the pre...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that, in order to realize pressure detection in the existing display panel, additional pressure detection sensors or pressure detection electrodes need to be added in the display panel, which increases the thickness of the display panel and the production cost.
