| titleOfInvention | Quantum dot LED light-emitting device and preparation method thereof |
| abstract | The invention discloses a quantum dot LED light-emitting device, which comprises a device body and also comprises: the diffusion plate, the LED light source and the bottom cover plate are sequentially arranged in the device body; and the quantum dot layer is arranged on the light incidence surface and/or the light emergence surface of the diffusion plate. The light-emitting device provided by the invention keeps the advantages of the LED in the aspects of price, service life and energy efficiency, and has the advantages of the OLED and the QLED: the area light source has no harm of blue light, spectrum close to natural light, high color rendering index, no stroboflash and no glare, can emit soft warm white light, positive white light or colored light without shadow, and has uniform illumination distribution. |
