Abstract

The invention discloses a display panel and a display, and the display panel comprises a first substrate, a first metal layer, a second metal layer, and an external power supply. The first metal layeris arranged on the first substrate, and the first metal layer is used for providing a signal channel for the display panel; the second metal layer is in contact with the first metal layer; wherein the metal activity of the first metal layer is higher than that of the second metal layer; the positive electrode of the external power supply is connected with the first metal layer, and the negative electrode of the external power supply is connected with the second metal layer. According to the technical scheme, the first metal layer and the second metal layer are arranged on the first substrate,the positive electrode of the external power supply is connected with the first metal layer, and the negative electrode of the external power supply is connected with the second metal layer, so thatthe first metal layer serves as the positive electrode in an exposed environment, oxidation reaction is avoided, and the effect of preventing the first metal layer from being corroded is achieved; andbubbles are prevented from being generated in a display area.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display. Background technique [0002] The display panel is usually composed of a TFT (Thin Film Transistor, thin film transistor) substrate and a CF (colorfilter, color filter) substrate. Usually, a metal film is plated on the TFT substrate to form various signal traces, and a color filter is plated on the CF substrate. The color group layer forms a color filter layer. The usual metal signal lines are mainly made of Al (aluminum) or Cu (copper). Due to the strong metal activity of Al / Cu, when the metal layer is exposed, Al / Cu is more likely to oxidize with water vapor, while Corroded, resulting in air bubbles in the display panel. [0003] The above content is only used to assist in understanding the technical solution of the present application, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The ...
