Abstract
The present invention provides a backlight and a display apparatus. The backlight comprises a substrate and at least one light source. The substrate has a first surface and a second surface along a thickness direction of the substrate. The first surface and the second surface are both continuous. The first surface has at least one light incident surface in the edge area. A light source is opposed to or in contact with the light incident surface to provide the substrate with light through the light incident surface.
Claims19
A backlight, comprising a substrate and at least one light source,
- wherein the substrate comprises a central area and at least one edge area disposed at a periphery of the central area;
- the substrate has a first surface and a second surface along a thickness direction of the substrate;
- the first surface and the second surface are both continuous;
- the first surface has at least one light incident surface in the edge area;
- the second surface has a second deflection surface in the edge area;
- the second deflection surface is a surface formed by the deviation of the second surface in the edge area away from a surface where the central area is located;
- the second deflection surface is configured to deflect and emit light entering the second deflection surface in the substrate;
- and an orthographic projection of the light incident surface on the substrate falls within an orthographic projection of the second deflection surface on the substrate;
- the light source is opposed to or in contact with the light incident surface to provide the substrate with light through the light incident surface, and light provided by the light source enters the substrate through the light incident surface and is guided by the substrate to emit evenly from the second surface;
- and
- the backlight further has a reflective layer, and the reflective layer covers a surface of the substrate other than the second surface and the light incident surface.
