Problems solved by technology

However, when the adhesion between the isolation structure and the substrate is not good, it is easy to cause the problem of peeling
In order to make the display panel have a higher resolution, the width of the isolation structure can be reduced, but this will lead to a higher risk of separation of the isolation structure

Embodiment Construction

[0061] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" may mean that other elements exist between two elements.

[0062] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, component...

Abstract

A display panel comprises a substrate, a first isolation structure, a second isolation structure and a plurality of light emitting structures. The first isolation structure is disposed on the substrate and has a plurality of openings. And the second isolation structure is stacked on the first isolation structure and is filled in the opening of the first isolation structure. The plurality of light-emitting structures are configured on the substrate, and the plurality of light-emitting structures are isolated from each other by the second isolation structure.

Description

technical field [0001] The present invention relates to a panel, and in particular to a display panel. Background technique [0002] In the process of the OLED display panel, an ink jet printing process (Ink Jet Printing; IJP) can be used to form the light emitting layer. The inkjet printing process injects liquid droplets into the openings defined by the isolation structures to form the light-emitting layer. However, when the adhesion between the isolation structure and the substrate is not good, the problem of peeling is likely to occur. In order to make the display panel have a higher resolution, the width of the isolation structure can be reduced, but this will lead to a higher risk of separation of the isolation structure. Contents of the invention [0003] The invention provides a display panel, which can strengthen the adhesion between the isolation structure and the substrate, thereby preventing the isolation structure from peeling off from the substrate. [000...
