Problems solved by technology

[0004] However, since the OLED display panel is encapsulated by glass glue, and the back glass and cover glass have certain toughness, when reducing the degree of deformation of the back glass and cover glass, the The toughness will also be reduced, which will cause the problem of cutting and breaking when cutting the display panel

Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] figure 1 It is a schematic structural diagram of a display panel motherboard provided by an embodiment of the present invention, see figure 1 , the display panel motherboard includes a cover plate 1 and a back plate 2 .

[0041] The cover plate 1 has a plurality of first encapsulation material patterns 11 and a plurality of second encapsulation material patterns 12 located outside each first encapsulation material pattern 11, and each of the plurality of first encapsulation material patterns 11 is first The packaging material pattern 11 is located on the outside of each display area on the backplane 2 .

[0042] Since there are not only a plurality of first encapsulation material patterns 11 on the cover plate 1 of the display...

Abstract

The invention discloses a display panel motherboard, a manufacturing method of the display panel and a display device, belonging to the field of display technology. The motherboard of the display panel includes a cover plate and a back plate; the cover plate has a plurality of first encapsulation material patterns and a plurality of second encapsulation material patterns located outside each first encapsulation material pattern, and the plurality of first encapsulation material patterns Each first encapsulation material pattern is located outside each display area on the backplane. The invention ensures that the cover plate and the back plate in the non-display area will not be deformed under the action of atmospheric pressure by making the cover plate and the back plate parallel, thereby eliminating Newton's rings. At the same time, since the present invention does not change the area of ​​the non-display area, the toughness of the back plate and the cover plate will not be changed, and the problem of cutting and breaking will not occur when the display panel is cut.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel motherboard, a manufacturing method of the display panel and a display device. Background technique [0002] An OLED (Organic Light-Emitting Diode, organic laser display) display panel is generally composed of a backplane glass and a cover glass printed with glass glue. The display panel can be obtained by laminating the backplane glass and the cover glass. However, there is a low-pressure blank area between two adjacent display areas in the display panel. Under the action of atmospheric pressure, the cover glass and back glass in the low-pressure blank area may be deformed, causing interference fringes to be generated by external incident light. That is to produce Newton's rings. The existence of Newton's rings will affect the display quality of the display panel. Therefore, it is necessary to improve the display panel to eliminate the Newton's rings generated ...
