Problems solved by technology

[0003] The main component of electronic equipment to realize the display function is the display panel. As the functions of electronic equipment become more and more powerful, it is required that the display panel not only has the function of image display, but also needs to integrate other functions, such as integrated touch electrodes with touch detection functions, etc., resulting in The display panel needs to have more wiring, which is not convenient for narrow bezel design and full screen design

Embodiment Construction

[0028] The following will clearly and completely describe the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] In the existing display panel, the test circuit is only used for the panel test before leaving the factory. It is used to test whether there is a data line disconnection or a sub-pixel that cannot be displayed normally. connect. The touch signal lines of the touch electrodes also need to be provided with separate routing lines and gating circuits, resulting in a large number of signal lines and gating circuits in the panel, which need to occupy a large step area.

Abstract

The invention discloses a display panel and electronic equipment. In the display panel, a test circuit is provided with a signal transmission line, the signal transmission line is electrically connected with a touch control signal line, and the signal transmission line is further electrically connected with a data line through a connecting wire. Thus, in the test stage, test signals can be input to the data line through the signal transmission line, and panel testing can be achieved through the signal transmission line; in the non-test stage, the connecting wire is disconnected from the test circuit, the signal transmission line outputs touch signals detected by touch electrodes, and touch detection is realized through the signal transmission line; thus, the signal transmission line in the test circuit can be used for panel testing and can also be used for touch detection, and the number of wires is reduced. The electronic equipment adopts the display panel, the number of wires can be reduced, and narrow frame design and full screen design can be achieved conveniently.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and more specifically, to a display panel and electronic equipment. Background technique [0002] With the continuous advancement 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 essential tool. [0003] The main component of electronic equipment to realize the display function is the display panel. As the functions of electronic equipment become more and more powerful, it is required that the display panel not only has the function of image display, but also needs to integrate other functions, such as integrated touch electrodes with touch detection functions, etc., resulting in The display panel needs to have more wiring, which is not convenient for narrow bezel design and full screen design. ...
