QUANTUM DOT LIGHT-EMITTING DEVICE, BACKLIGHT MODULE, AND DISPLAY DEVICE

摘要

Embodiments of the disclosure provide a quantum dot light emitting device and a backlight module, where the quantum dot light emitting device includes: a quantum dot film including a plurality of quantum dots; a backlight source configured to emit light rays in a first band to the quantum dot film to excite the plurality of quantum dots to emit light rays in a second band; a wavelength selector, arranged between the quantum dot film and the backlight source, configured to transmit the light rays in the first band, and to reflect the light rays in the second band emitted by the quantum dot film to the wavelength selector; and a groove-shaped bracket including two side brackets arranged opposite to each other, and a bottom plate connected between the two side brackets, wherein the backlight source is fixed on the bottom plate, and both ends of the quantum dot film and the wavelength selector are arranged on the two side brackets. The quantum dot light emitting device and the backlight module according to the disclosure improve the utilization ratio of the light rays.
