Embodiment Construction

[0033]The present invention is further detailed in conjunction with the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are merely illustrative of the invention and are not limited thereto. It will also be noted that in order to facilitate the description, only the parts associated with the present invention are shown in the drawings rather than all structures.

[0034]As described in the background, the existing silicon-organic light-emitting display panel is present in a stroner problem caused by the transverse flow of the current. According to the inventors, it was found that the above problem is that the cathode of the display panel in the prior art is a whole electrode without pattern structure, and the cathode area between adjacent light-emitting regions is large, so that the cathode resistance between adjacent light-emitting regions is smaller. The flow of transverse flow in the cathode is large, thereby causing the occur...

Abstract

The invention discloses a display panel and a preparation method thereof. The display panel comprises a substrate, and a light-emitting device layer which comprises a first electrode layer, a light-emitting layer and a second electrode layer which are stacked from one side of the substrate. The first electrode layer comprises a plurality of first electrodes which are insulated from one another, and each first electrode corresponds to one light-emitting area. The second electrode layer comprises a body electrode part and a first hollow part, the body electrode part is integrally communicated, and the first hollow part is at least located between part of adjacent light-emitting areas emitting light of different colors. According to the technical scheme provided by the embodiment of the invention, the first hollow part in the second electrode layer enables the size of the body electrode part between the light-emitting areas with different colors to be reduced, so that the cross sectional area of the body electrode part between the light-emitting areas with different colors is reduced, the resistance of the body electrode part between the light-emitting areas with different colors is increased, the transverse current is reduced, the cross color phenomenon caused by the transverse current between light-emitting areas with different colors is reduced, and the display effect is improved.

Description

Technical field[0001]Embodiments of the present invention relate to the field of display, and more particularly to a display panel and a preparation method thereof.Background technique[0002]With the development of display technology, organic light-emitting display technology applications are increasingly wide.[0003]The silicon-based organic light-emitting display panel has the advantage of small pixel, high pixel density, widely used in military venues, VR / AR, and automatic driving.[0004]However, the existing silicon-based organic light-emitting display panel has a stroner problem caused by the transverse flow of the current.Inventive content[0005]The present invention provides a display panel and a preparation method thereof to achieve a transverse flow between the current between different light emitting devices, thereby reducing the colored phenomenon, and enhances the display effect.[0006]In the first aspect, the embodiment of the present invention provides a display panel, wh...
