Abstract
Official abstract text for this publication.
The present invention provides a diffuser plate assembly. The diffuser plate assembly includes a first diffuser plate and a second diffuser plate located under the first diffuser plate, and a gap is formed therebetween. Correspondingly, the present invention also provides a backlight comprising the diffuser plate assembly and a display device comprising the backlight. Compared with the prior art, the diffuser plate assembly provided by the present invention can enable light emitted by a light source to irradiate a display panel more uniformly, and the thicknesses of the backlight and the display device can be reduced.
First claim
Opening claim text (preview).
What is claimed is: 1. A diffuser plate assembly, wherein the diffuser plate assembly includes a first diffuser plate and a second diffuser plate located under the first diffuser plate, and a gap is formed between the first diffuser plate and the second diffuser plate; wherein there is at least one support provided between the first diffuser plate and the second diffuser plate, and the support separates the opposed surfaces of the first diffuser plate and the second diffuser plate to form the gap; and wherein a first lock-in member is provided at the end of the support corresponding to the first diffuser plate, and a first groove is provided at a position of the first diffuser plate corresponding to the first lock-in member, the first lock-in member being extended and locked into the first groove; and/or a second lock-in member is provided at the end of the support corresponding to the second diffuser plate, and a second groove is provided at a position of the second diffuser plate corresponding to the second lock-in member, the second lock-in member being extended and locked into the second groove. 2. The diffuser plate assembly according to claim 1 , wherein, the support is made of a transparent material. 3. The diffuser plate assembly according to claim 1 , wherein, a plurality of the supports are provided between the first diffuser plate and the second diffuser plate. 4. The diffuser plate assembly according to claim 1 , wherein, the height of the gap is ranged from 4 mm to 6 mm. 5. The diffuser plate assembly according to claim 1 , wherein, a diffusion film layer is provided on the upper surface of the first diffuser plate. 6. A backlight including light sources and a diffuser plate assembly located above the light sources, wherein, the diffuser plate assembly is the diffuser plate assembly according to claim 1 . 7. A display device including a backlight, wherein, the backlight is the backlight according to claim 6 .
