Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] As mentioned in the background, in the existing display panel, electrode layers are respectively provided on the color filter substrate and the array substrate. When the display panel is under pressure, the distance between the two electrode layers becomes smaller due to the deformation of the color filter substrate, which in turn causes the capacitance between the two electrode layers to change. Pressure detection is performed by detecting the change in...

Abstract
The invention discloses a display panel and an electronic device. The display panel comprises a cover plate and an array substrate which are oppositely arranged. The cover plate comprises a first substrate and a first electrode, wherein a plurality of supporting columns and a plurality of second supporting columns are arranged on the surface of the side, facing the array substrate, of the first substrate, and the heights of the first supporting columns are larger than the heights of the second supporting columns; the surface, facing the array substrate, of the first substrate, the surfaces of the first supporting columns and the surfaces of the second supporting columns are covered with the first electrode. The array substrate comprises a second substrate, a second electrode and a plurality of third electrodes, wherein the second electrode is arranged on the side, facing the cover plate, of the second substrate and located between the third electrodes and the second substrate; in the direction perpendicular to the second substrate, the third electrodes are arranged opposite to at least one second supporting column, and a first gap with a preset height is formed between the first electrode covering the second supporting columns and the third electrodes. The display panel has high precision during pressure detection.
Description
technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a display panel and electronic equipment. Background technique [0002] With the development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable important tool missing. [0003] An important part of an electronic device to realize a display function is a display panel. With the continuous improvement of user application requirements and user experience, the pressure detection function has become an important function of the display panel. Taking the liquid crystal display panel as an example, the conventional display panel has electrode layers respectively disposed on the color filter substrate and the array substrate. When the display panel is under pressure, the distance betwee...
