Abstract

The invention provides a display panel and a preparation method thereof, the display panel comprises a driving circuit layer, an electrode layer, a light-emitting layer and a second electrode, the driving circuit layer comprises a plurality of transistors and a plurality of signal lines, the electrode layer is formed on one side of the driving circuit layer, and the second electrode is formed on the other side of the driving circuit layer. The electrode layer comprises a first electrode arranged in the display area and a binding terminal arranged in the binding area, the first electrode is connected with the transistor, the binding terminal is connected with the signal line, the light-emitting layer is formed on the side, away from the driving circuit layer, of the electrode layer, and the second electrode is formed on the side, away from the electrode layer, of the light-emitting layer. The first electrode and the binding terminal are both prepared from the electrode layer and can be prepared by adopting the same photomask, so that a photomask for independently preparing the binding terminal is omitted, and the cost is reduced.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display panel and a manufacturing method of the display panel. Background technique [0002] Current display panels mostly use Cu or Cu alloys with good electrical conductivity as signal lines, and the signal lines are connected to binding terminals arranged on the periphery of the display area, and various signals are received through the binding terminals. Since Cu is easily oxidized, there is a risk of corrosion in direct exposure. Therefore, in current products, corrosion-resistant metal Ti is used to make binding terminals. However, the binding terminals in current products need to be made with an additional mask, so that the display The cost of the panel is higher. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a display panel and a method for manufacturing the display panel, so as to alleviate the technical problem of ...
