A display panel and its packaging method, manufacturing method, and display device

Abstract

The application discloses a display panel, a packaging method thereof, a preparation method, and a display device, which are used to avoid poor color mixing of the non-rectangular display panel and improve the display yield of the non-rectangular display panel. An embodiment of the present application provides a method for packaging a display panel, the method comprising: disposing an encapsulant on the encapsulation substrate to form an encapsulation cover, the area on the encapsulation cover where the encapsulant is not provided includes a plurality of arrays The shape of each sub-region is non-rectangular; the packaging cover plate is used to package the backplane to obtain a packaged display panel, so that the shape of the light-transmitting area of ​​the display panel is the shape of the sub-region.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a packaging method thereof, a manufacturing method, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) display includes passive matrix organic electroluminescent diode (Passive matrix OLED, PMOLED) display and active matrix organic electroluminescent diode (Active-matrix OLED, AMOLED) display, the former is mainly used For small-size panels, corresponding to mobile phones and mobile applications, the latter is mainly used for large-size panels, corresponding to applications such as display screens and TVs. There are two ways to realize AMOLED display: 1. Combining a backplane prepared by low temperature polysilicon technology (LTPS) with a fine metal mask (FMM Mask); 2. Using an oxide (Oxide) backplane, white light OLED (WOLED) and color Membrane bound. [0003] Now the combination of LTPS backplane and FMM Mask h...

Problems solved by technology

In the prior art, in the process of preparing a circular display panel, there are two kinds of masks used for evaporating luminescent materials. One is to use a double-layer mask. On the surface of the welded open metal mask (Open Mask), the sheet-shaped fine metal mask (FMM Sheet) is stretched and welded. However, the accuracy of the FMM Sheet is greatly affected by the Open Mask, and the double-layer mask The degree of bonding between the boards is not particularly good; the other is the welding composition of Cover Mask, Howling Mask and FMM, where the opening shape of the FMM effective area (AA area) is Circular, but the strain of the circular FMM is not uniform when the mesh is stretched, and it is prone to large wrinkles during the welding process. big gap

That is to say, in the prior art, the process of preparing a circular display panel will cause serious poor color mixing in some areas of the display panel, which will affect the normal display yield.
