Problems solved by technology

A special-shaped display panel is formed by removing a part of the substrate area on the basis of a conventional display panel. Usually, the corresponding part is removed by direct laser cutting. The section of the organic film layer in the thin-film encapsulation layer is exposed to the air, thus forming a path for moisture intrusion, resulting in encapsulation failure, and causing dark spots and other defects in the display area.

Embodiment Construction

[0037] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The invention discloses an irregularly-shaped display panel, a manufacturing method thereof, a display device and a carrying table, and relates to the field of display technology. The manufacturing method comprises the following steps: manufacturing a substrate, and forming a display area, a first non-display area and a second non-display area on the substrate; carrying out cutting and hollowing on at least a part of the substrate inside a region restricted by a second retaining wall inside the second non-display area to form a first trepanning region, and putting the substrate on which the first trepanning region is formed on the carrying table; carrying out coverage on the region restricted by the second retaining wall inside the second non-display area by adopting a first mask, and evaporating an electroluminescent structure in the display area; taking down the first mask, carrying out coverage on the region restricted by the second retaining wall inside the second non-display areaby adopting a second mask, carrying out thin film packaging on the side, away from the substrate, of the electroluminescent structure to form a thin film packaging layer, and enabling a space betweena first retaining wall and the second retaining wall to be covered with the thin film packaging layer. Thus, the thin film packaging reliability of the irregularly-shaped display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a special-shaped display panel, a manufacturing method thereof, a display device and a carrier. Background technique [0002] In recent years, Organic Light-Emitting Diode (OLED, Organic Light-Emitting Diode) has become a very advanced display industry at home and abroad. , fast response time, high luminous efficiency, thin panel thickness, large-size and bendable panels can be produced, simple manufacturing process, and low cost. [0003] OLED devices generally use active metals as cathodes, which are easy to react with water vapor and affect charge injection, and the organic light-emitting materials in the device will also chemically react with water and oxygen. These reactions reduce the performance and service life of OLED devices. Therefore, OLED devices need to use good packaging technology to isolate the intrusion of water vapor and oxygen. Thin Film Encapsul...
