Embodiment Construction

[0026] 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.

[0027] In the prior art, in order to increase the screen-to-body ratio of the display panel, it is necessary to reduce the frame of the display panel. However, since the narrow frame of the display panel limits the width of the wiring in the non-display area, the resistance of the wiring is relatively large, and the signal transmitted by the wiring has a relatively large voltage drop, which easily causes problems such as uneven brightness of the display panel. For example, the width of the ELVDD and ELVSS lines in...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes a substrate, a first electrode layer, a light emitting layer and a second electrode layer which are stacked in sequence. The substrate includes a display area and a non-display area surrounding the display area, and the non-display area is provided with a conductive layer. The conductive layer is used for inputting a driving signal to the second electrode layer. The non-display area includes a first area and a second area, and the second area is set on a side of the first area away from the display area. The first region includes a first edge, the first edge coincides with the edge of the second region adjacent to the first region, and the first edge coincides with the vertical projection of the edge of the light emitting layer on the substrate. In the second region, the second electrode layer is in contact with the overlapping portion of the conductive layer on the vertical projection of the substrate. The solutions of the embodiments of the present invention meet the display uniformity requirement of the display panel while ensuring that the display panel has a small frame.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of full screens, there is an increasing demand for increasing the screen-to-body ratio of the display panel, so it is necessary to further reduce the frame of the display panel. However, as the frame of the display panel becomes narrower and narrower, the width of the traces at the frame becomes narrower and narrower, and the voltage drop of the voltage passing through the traces in the traces becomes larger and larger, so it is easy to cause The display panel shows uneven brightness. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device, which meet the display uniformity requirements of the display panel while ensuring that the display panel has a small frame. [0004] In a first aspect, an embodim...
