Abstract
A backlight assembly includes an optical plate, a light source provided near the optical plate, and a brightness redistribution film provided above the optical plate. When light emitted from the light source passes through the optical plate and the brightness redistribution film, a front view angle brightness measured in a normal direction of a light exiting surface of the brightness redistribution film relative to a maximum brightness emitted from the backlight assembly has a brightness ratio N, wherein the brightness ratio N is greater than or equal to 60% and is smaller than 100% (60%≤N<100%).
Claims20
A backlight assembly, comprising:
- an optical plate;
- a light source, provided near the optical plate;
- and
- a brightness redistribution film, provided above the optical plate and having a light exiting surface;
- wherein, when light emitted by the light source passes through the optical plate and the brightness redistribution film, a front view angle brightness measured in a normal line direction of the light exiting surface of the brightness redistribution film has a brightness ratio relative to a maximum brightness emitted from the backlight assembly, and the brightness ratio is greater than or equal to 60% and smaller than 100%.
A display device, comprising:
- a display panel;
- a backlight assembly, provided on one side of the display panel, comprising:
- an optical plate;
- a light source, provided near the optical plate;
- and
- a brightness redistribution film provided above the optical plate and having a light exiting surface;
- wherein, when light emitted by the light source passes through the optical plate and the brightness redistribution film, a front view angle brightness measured in a normal line direction of the light exiting surface of the brightness redistribution film has a brightness ratio relative to a maximum brightness emitted from the backlight assembly, and the brightness ratio is greater than or equal to 60% and smaller than 100%.
