Abstract
The utility model discloses an OLED (Organic Light Emitting Diode) display and a special packaging cover plate of the OLED display, wherein the OLED display has a good effect of bonding between a packaging cover plate and a substrate. The OLED display disclosed by the utility model comprises the substrate, an OLED device which is arranged on the substrate and the packaging cover plate for the OLED display. A mounting surface for bonding with the substrate on the packaging cover plate is provided with a concave and convex structure which is formed through surface roughness increase treatment. Since the surface roughness increase treatment is conducted to the mounting surface, the bonding area between the packaging cover plate and the substrate is increased, the bonding strength is improved and the effect of bonding between the packaging cover plate and the substrate is effectively improved.
Description
Technical field
The utility model relates to the OLED display.
Background technology
As shown in Figure 1, traditional OLED display comprises substrate 2, be positioned at the OLED device 3 on the substrate 2 and the encapsulation cover plate 1 of this OLED device 3, a groove that area is bigger is arranged in the described encapsulation cover plate 1, drier 4 is posted in the middle part of this groove, and the position of groove periphery forms the face of pasting with substrate that mounts 11.Encapsulation cover plate 1 is made by glass plate or metallic plate usually, its further groove be molded over coverage mask plate on glass plate or the metallic plate, adopt chemical etching to handle then.The method of making at present the OLED display is after etching groove on the encapsulation cover plate 1, drier 4 is sticked in the groove, thereby and then encapsulation cover plate 1 pasted on the substrate 2 that has OLED device 3 finish encapsulation.In the said method,,, can influence the sticking Quality between encapsulation cover plate 1 and the substrate 2, cause product encapsulation quality to descend if these foreign substance cleaning are unclean because the etching meeting of groove produces foreign matter at encapsulation cover plate 1.
The utility model content
The application aims to provide OLED display and the special-purpose encapsulation cover plate thereof that sticking effect is good between a kind of encapsulation cover plate and the substrate.
The application's OLED display comprises substrate, is positioned at the OLED device on the substrate and the encapsulation cover plate of this OLED device, and the mask of pasting with substrate on the described encapsulation cover plate that mounts has to increase through surface roughness and handles formed concaveconvex structure.
Concrete, described concaveconvex structure is to handle formation by carry out chemical etching on the face of mounting.Can on the face of mounting, form point, line and the various lines of depression or projection during chemical etching.
Perhaps, described concaveconvex structure is to form by carry out blasting treatment on the face of mounting.
Adopt blasting treatment may cause encapsulation cover plate (as adopting glass) to produce slight crack, so recommend to adopt chemical etching.
The special-purpose encapsulation cover plate of above-mentioned OLED display comprises being used for the face that mounts pasted with substrate, and the described mask that mounts has to increase through surface roughness and handles formed concaveconvex structure.
Concrete, described concaveconvex structure is to handle formation by carry out chemical etching on the face of mounting.
Perhaps, described concaveconvex structure is to form by carry out blasting treatment on the face of mounting.
Increase processing owing to carried out surface roughness, therefore increased the bonding area between encapsulation cover plate and the substrate, thereby improved sticking strength, effectively improved sticking effect between encapsulation cover plate and the substrate at the face of mounting.

Fig. 2 is the encapsulation cover plate inner side plane figure of the embodiment of the present application 1.
Fig. 3 is the encapsulation cover plate inner side plane figure of the embodiment of the present application 2.
Fig. 4 is the encapsulation cover plate inner side plane figure of the embodiment of the present application 3.
Fig. 5 is the encapsulation cover plate inner side plane figure of the embodiment of the present application 4.
Embodiment
Embodiment 1: as shown in Figure 1, 2, have on the face that mounts 11 that is used on the encapsulation cover plate 1 pasting with substrate 2 through chemical etching and handle the cross cut that forms projection.
Embodiment 2: as shown in Figure 3, mount the slanted bar line that has the depression that forms through the chemical etching processing on the face 11.
Embodiment 3: as shown in Figure 4, mount the sandblast face that has on the face 11 through blasting treatment formation.
Embodiment 4: as shown in Figure 5, mount face 11 and have the point-like groove of handling formation through chemical etching.
Compare the smooth in the past face that mounts, the face that mounts 11 of said structure increased and substrate 2 between bonding area, thereby improve sticking strength, effectively improved sticking effect between encapsulation cover plate and the substrate.
