Embodiment Construction

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

[0029] The embodiment of the present application is aimed at the high-resolution display panel of the current technology. Due to the short signal wiring between the connection test terminal and the data transmission terminal, the internal driving circuit of the display panel is damaged by electrostatic current. can solve the above-mentioned defects.

[0030] see Figure 1 to Figure 4 The embodiment of the present application provides a display panel 10, including a display area 11, a data tran...

Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a test terminal, a data transmission terminal and a signal wire, the first end of a test signal wire is electrically connected with the test terminal, the second end of the test signal wire is electrically connected with the data transmission terminal, the test signal wire at least comprises a first short-circuit bar and a second short-circuit bar which are arranged separately, orthographic projections of the first short-circuit bar and the second short-circuit bar on the display panel are located in a line breaking area, so that the test signal wire forms a winding structure between the test terminal and the data transmission terminal, and meanwhile, the part of the test signal wire in the line breaking area is subjected to laser cutting, so that the test signal wire has at least two breaking positions in the line breaking area; therefore, no effective connection path is between the test terminal and the data transmission terminal, the path from static electricity to a driving chip is blocked, and the antistatic capability of the display panel is improved.

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] In the field of liquid crystal display panels, Electro-Static Discharge (ESD), as an electromagnetic compatibility test, is an important means to measure the quality of a panel. In order to reduce the risk of electrostatic discharge, people in the industry usually design an anti-static ring (ESD Ring) around the display area of ​​the display panel to reduce the risk of the display panel being damaged by static electricity. [0003] However, in the mass-produced high-resolution liquid crystal display panels in the industry, since the test terminals and the COF are arranged along the longitudinal direction, the test terminals are exposed, and the signal traces connecting the test terminals and the data transmission terminals are relatively short. The static electricity generated during the LCD panel cut...
