Embodiment Construction

[0029] The specific implementations of the mask module, the organic electroluminescence display panel and the manufacturing method thereof provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] The shapes and sizes of the regions in the drawings do not reflect the true proportions of the mask module, but are only intended to schematically illustrate the content of the present invention.

[0031] An embodiment of the present invention provides a mask module, such as image 3 As shown, it includes: at least two open mask plates 100 and 200; each open mask plate 100 and 200 has an opening area 101 and 201 corresponding to the display area of ​​at least one display substrate; in each display area a There is at least one island figure b inside;

[0032] The opening areas 101 and 201 of the open mask plates 100 and 200 corresponding to the same display area do not overlap each other, and the openi...

Abstract

The invention discloses a manufacturing method of a mask module, a film layer and an organic electroluminescent display panel, which adopts a plurality of open mask plates instead of an existing open mask plate to produce an island pattern in the display area The film layer, the opening areas of each open mask plate do not overlap each other and the opening areas are spliced ​​to form a graphic that surrounds the display area of ​​the island figure, so that it can be guaranteed that there will be no Contains occlusion patterns that need to be connected to edges through connected structures. Using the above-mentioned open mask plates as the shielding patterns in turn, and vapor-depositing the same material on the same motherboard, the vapor-deposited film layer surrounding the island pattern can be formed at the display area of ​​the motherboard corresponding to each display substrate, so that the The pattern of the shielding film layer is not affected by the connected structure, therefore, an organic light emitting display panel including at least one island pattern can be manufactured according to requirements.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a mask plate module, an organic electroluminescent display panel and a manufacturing method thereof. Background technique [0002] The display area (AA) of a conventional organic electroluminescence display panel (OLED) screen is generally a regular figure such as a rectangle. In order to meet special needs, the display area of ​​the OLED screen is also required to be made into special irregular graphics, such as a specific logo display, and for example, a borderless screen requires a special-shaped display if the camera, earpiece, etc. are placed in the display area. [0003] Usually, in the OLED manufacturing process, the evaporation of the light-emitting functional layer (EL) organic material is done using an open mask (Open Mask), such as figure 1 As shown, the open mask plate is provided with an opening A, that is, a hollow area, in the display area of ​​each display subst...
