Abstract
A diffusing plate includes a body, a plurality of partitions and a diffusing member. The body has a lower face through which light enters the body and an upper face through which the light exits from the body. The body includes a plurality of domains having horizontal polygonal cross-sections. The partitions are disposed within the body. The partitions form the boundaries of the plurality of domains. The diffusing member is disposed between the lower face and the upper face of the body. The diffusing member is configured to diffuse the light entering the body to provide diffused light exiting the body. Therefore, the luminance uniformity of each domain is enhanced, and the interference between domains is minimized.
Claims30
A diffusing plate, comprising:
- a body having a lower face through which light enters the body and an upper face through which the light exits from the body, the body including a plurality of domains having horizontal polygonal cross-sections;
- a plurality of partitions disposed within the body, the partitions being configured to form the boundaries of the plurality of domains;
- and
- a diffusing member disposed between the lower face and the upper face of the body, the diffusing member being configured to diffuse the light entering the body to provide diffused light exiting the body.
A diffusing plate, comprising:
- a body having a lower face through which light enters the body and an upper face through which the light exits from the body, the body including a plurality of domains having horizontal circular cross-sections;
- a plurality of partitions disposed within the body, the partitions being configured to form the boundaries of the plurality of domains;
- and
- a diffusing member disposed between the lower face and the upper face of the body, the diffusing member being configured to diffuse the light entering the body to provide diffused light exiting the body.
A backlight assembly, comprising:
- a plate having a lower face through which light enters the plate and an upper face through which the light exits from the plate, the plate including a plurality of domains having horizontal polygonal cross-sections;
- a plurality of partitions disposed within the plate, the partitions being configured to form the boundaries of the plurality of domains;
- a diffusing member disposed between the lower face and the upper face of the plate, the diffusing member being configured to diffuse the light entering the plate to provide diffused light exiting the plate;
- a plurality of light sources correspondingly arranged with the plurality of domains;
- and
- a driving substrate disposed under the plate, the driving substrate being configured to drive the light sources.
