Abstract
A quantum dot lighting device includes a quantum-dot-lighting layer and two main structural layers being arranged at two sides of the quantum-dot-lighting layer along a vertical direction. The quantum-dot-lighting layer includes a red lighting unit, a green lighting unit, and a red lighting unit. The red lighting unit includes red quantum dots, the green lighting unit includes green quantum dots, and the blue lighting unit includes blue quantum dots. A number of the blue quantum dots is larger than the number of the green quantum dots, and the number of the green quantum dots is larger than the number of the red quantum dots. With the configuration, the material of the quantum dots may be reduced, and the pureness of the white light beams may be enhanced.
