Abstract
The utility model discloses an OLED (Organic Light Emitting Diode) display with higher image contrast. The OLED display disclosed by the utility model comprises a transparent substrate, an OLED device which is arranged on the transparent substrate and a packaging cover plate for the OLED device. A black coating layer is arranged on the inner surface of the packaging cover plate. The OLED display disclosed by the utility model can also adopt the following structure that the OLED display comprises the transparent substrate, the OLED device which is arranged on the transparent substrate and the packaging cover plate for the OLED device, and the packaging cover plate is made of a black material. No matter that the black coating layer is arranged on the inner surface of the packaging cover plate or the packaging cover plate is directly made of the black material, the packaging cover plate can take an effect of absorbing ambient light which enters the OLED display and the image contrast of the OLED display is improved.
Description
Technical field
The utility model relates to the OLED display.
Background technology
Traditional OLED display comprises transparency carrier, be positioned at the OLED device on the transparency carrier and the encapsulation cover plate of this OLED device, and described encapsulation cover plate adopts glass plate or metallic plate to make.During use, this OLED device is outwards luminous by transparency carrier, but meanwhile, extraneous surround lighting enters this OLED display and the reflection of packed cover plate from transparency carrier again, thereby causes the picture contrast of OLED display to descend.
The utility model content
The utility model aims to provide the higher OLED display of a kind of picture contrast.
OLED display of the present utility model comprises transparency carrier, be positioned at the OLED device on the transparency carrier and the encapsulation cover plate of this OLED device, and the inner surface of described encapsulation cover plate is provided with black coating.
OLED display of the present utility model also can adopt following structure: the OLED display comprises transparency carrier, be positioned at the OLED device on the transparency carrier and the encapsulation cover plate of this OLED device, and described encapsulation cover plate is made by black material.
There is the multiple material that can be used for forming above-mentioned black coating or black encapsulation cover plate in the prior art, for example carbon black.
No matter be on the inner surface of encapsulation cover plate, to establish black coating or the encapsulation cover plate that directly adopts black material to make, all make this encapsulation cover plate to play absorption, improve the picture contrast of OLED display the surround lighting that enters the OLED display.
Description of drawings
Fig. 1 is a kind of structural representation of the application OLED display.
Fig. 2 is the another kind of structural representation of the application OLED display.
Embodiment
OLED display as shown in Figure 1, comprise transparency carrier 2, be positioned at the OLED device 4 on the transparency carrier 2 and the encapsulation cover plate 1 of this OLED device 4, the inner surface of encapsulation cover plate 1 is provided with black coating 101, is provided with drier 3 between black coating 101 and the OLED device 4.
OLED display as shown in Figure 2 comprises transparency carrier 2, is positioned at the OLED device 4 on the transparency carrier 2 and the encapsulation cover plate 1 of this OLED device 4, and encapsulation cover plate 1 is made by black material, is provided with drier 3 between encapsulation cover plate 1 and the OLED device 4.
OLED display shown in Fig. 1,2 is all outwards luminous by transparency carrier 2, and extraneous surround lighting enters the OLED display of packed cover plate 1(Fig. 1 behind this OLED display by the black coating 101 absorbing environmental light on the encapsulation cover plate 1 from transparency carrier 2, the OLED display of Fig. 2 is by encapsulation cover plate 1 bulk absorption surround lighting) absorb, thereby therefore can packed cover plate 1 reflection and the light that OLED device 4 itself is sent are constituted disturb, improve the picture contrast of OLED display.
