BACKLIGHT UNIT OF DISPLAY DEVICE AND WHITE LED |
| 摘要 |
A backlight unit of a display device includes a light bar and a light guide plate (LGP), where a plurality of ultraviolet (UV) light emitting diodes (LEDs) are arranged on the light bar, and a light incident surface of the LGP and the UV LEDs are oppositely arranged. at least one red-green-blue (RGB) quantum dot phosphor layer is arranged in a path of a light from the UV LEDs to a light emitting surface of the LGP. The RGB quantum dot phosphor layer comprises a red quantum dot fluorescence film, a green quantum dot fluorescence film, and a blue quantum dot fluorescence film that are successively arranged. |
