Back Cover for Backlight Source, Backlight Source, and Display Apparatus |
| 摘要 |
The present invention provides a back cover for a backlight source, a backlight source and a display apparatus. The back cover includes at least one reflection surface arranged on one surface of the back cover. The reflection surface includes a first reflection region and a second reflection region, each of which includes a plurality of concave arc-shaped regions. The concave arc-shaped regions of the first reflection region have curvature increasing toward the second reflection region, and the concave arc-shaped regions of the second reflection region have curvatures decreasing in a direction away from the first reflection region. The concave arc-shaped region having a maximum curvature in the first reflection region is connected with the concave arc-shaped region having a maximum curvature in the second reflection region. |
