Problems solved by technology

[0003] Existing test terminal designs generally include bottom metal, surface electrode and via design connecting the bottom metal and surface electrode. The bottom metal is usually a metal material that is easily corroded, and the surface electrode is an indium tin oxide material with strong corrosion resistance. The underlying metal adopts a monolithic design. Once the surface electrode is corroded by external water vapor, it will spread rapidly along the underlying metal, resulting in aggravated corrosion and affecting the normal input of test signals.

Abstract

The invention discloses a display panel and a test terminal thereof, the display panel comprises a test wire, the test terminal is connected to the test wire, the test terminal comprises a metal layer, an insulating layer and a conductive layer, the metal layer comprises a first metal gasket, a second metal gasket, a first connecting wire and a second connecting wire, the first metal gasket and the second metal gasket are arranged at an interval, the first metal gasket is connected with the test wire through the first connecting wire, the second metal gasket is connected with the test wire through the second connecting wire, and the first connecting wire, the second connecting wire and the test wire are different in wire direction. According to the scheme, the corrosion resistance of the test terminal 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 test terminal thereof. Background technique [0002] In the production process of the display panel, in order to ensure the quality of the display panel and eliminate defective products, it is particularly important to inspect them. The driving wiring inside the display panel, such as scanning lines, data lines and other signal lines, can be shipped only after they are tested and meet the regulations. A conventional detection step is to use the test terminal of the test wire to connect to an external signal, so as to detect whether the display panel is normal. [0003] Existing test terminal designs generally include bottom metal, surface electrode and via design connecting the bottom metal and surface electrode. The bottom metal is usually a metal material that is easily corroded, and the surface electrode is an indium tin oxide material with st...
