Embodiment Construction

[0047]Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electr...

Abstract

The present application discloses a display panel and a display device, which relate to the field of display technology, wherein the display panel includes: N touch electrode groups, each touch electrode group includes several touch electrodes, each touch electrode is arranged in an array and Located in the display area, N≥1, and N is a positive integer; the control chip and the common voltage lines located in the non-display area, the number of common voltage lines is M, M=N; the common voltage control circuit, the common voltage control circuit and each The touch electrodes are electrically connected, and are electrically connected to the common voltage line; in the standby stage, the common voltage control circuit short-circuits each touch electrode in the N touch electrode groups, so that the same group of touch electrodes is short-circuited to the same line The common voltage line, the control chip controls the common voltage line to receive the standby detection signal; in the touch stage, the common voltage control circuit disconnects the connection between each touch electrode and the common voltage line, and each touch electrode receives a touch signal. In this way, it is beneficial to reduce the power consumption of the display panel in the standby phase.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel and a display device. Background technique [0002] Currently, the touch screen technology has gradually replaced the button technology to become the mainstream technology of mobile terminals and the like. Touch screen technology is a technology that determines the input information by detecting the touched position (in the form of coordinates) and sending it to the CPU when a finger, pen, etc. touch the touch screen installed on the front of the display. At present, the application range of touch screen is very wide, and the main products include mobile terminals such as touch mobile phones and notebook computers, as well as human-machine display interfaces in the industrial automation industry. [0003] When the existing touch screen enters the standby state, the touch screen enters the dormant state without displaying, and in order to accurately lo...
