Embodiment Construction

[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0041] As mentioned in the background, the existing display panels have the problem of poor brightness uniformity. The inventors have found through research that the reason for this problem is that the light-emitting devices in the display panel are generally connected by a common cathode. Because the area of ​​the cathode is generally large, and the cathode has a voltage drop (IR Drop), the cathode potential of the light-emitting device at different positions is different, and the luminous brightness is different...

Abstract

Embodiments of the present invention disclose a display panel and a manufacturing method of the display panel. The display panel includes a substrate; an anode, a light-emitting layer and a cathode are stacked and arranged on one side of the substrate in sequence; a first encapsulation layer is arranged on the side of the cathode away from the substrate and covers the cathode; The first encapsulation layer includes a plurality of first via holes; an auxiliary electrode is arranged on the side of the first encapsulation layer away from the substrate, and the auxiliary electrode contacts the cathode through the first via holes; Two encapsulation layers are disposed on the side of the auxiliary electrode away from the substrate. Compared with the prior art, the embodiment of the present invention achieves the technical effects of improving the brightness uniformity of the display panel, ensuring a better packaging effect and lowering the manufacturing cost.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a method for manufacturing the display panel. Background technique [0002] With the rapid development of display technology, users have higher and higher requirements on the display effect of the display screen, and the research on the display effect in the industry has always kept high attention. Among them, the organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has the advantages of high luminous brightness, light and thin volume, fast response speed, and easy to realize color display and large-screen display, etc., and has broad application prospects. However, the existing display panels have the problem of poor brightness uniformity. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a manufacturing method of the display panel, so as to improve...
