Quantum dot module, quantum dot light-emitting device, display equipment and eye protection method

Abstract

The invention discloses a quantum dot module, a quantum dot light-emitting device, display equipment and an eye protection method. The quantum dot module comprises a quantum dot material capable of emitting light when being excited, wherein when the quantum dot material is excited, the spectral function of the light emitted by the quantum dot module in a certain direction in a visible light rangemeets the following conditions: F(lambda)=[xi]R[phi]R([lambda]R, [delta][lambda]R, AR)+ [xi]G[phi]G([lambda]G, [delta][lambda]G, AG)+ [xi]B[phi]B([lambda]B, [delta][lambda]B, AB), the following i represents R, G or B, [phi]i([lambda]i, [delta][lambda]i, Ai) is a Gaussian function about the peak wavelength [lambda]i, the corresponding half-peak width [delta][lambda]i and the peak correction value Ai of the three-primary color spectrum, [xi]i is a correction factor related to [alpha]i and [beta]i, [alpha]i is a proportionality coefficient of red light or green light or blue light contained in different colors, and [beta]i is a correlation coefficient of a Gaussian function corresponding to a spectral peak of the red light or green light or blue light. According to the invention, the color purity of light emitted by the quantum dot module is high, color stimulation the same as that of a common light source can be generated with less energy, and damage of light energy to human eyes is reduced.

Description

technical field [0001] The invention relates to the technical field of quantum dot materials, in particular to a quantum dot module, a quantum dot light-emitting device, a display device and an eye protection method. Background technique [0002] As an excellent semiconductor material, quantum dot materials have already shown their talents in the biological industry and optoelectronic industry. Quantum dot materials can change the bandgap width by changing their size, thereby correspondingly changing the wavelength range of the absorption spectrum and the wavelength range of the emission spectrum, thereby realizing energy conversion such as photoluminescence and electroluminescence. [0003] With the development of the times, in the face of large and small screens and colorful lights, people use their eyes more and more frequently, and healthy eye protection has become a hot topic. There are rod cells and cone cells on the retina of the human eye. The rod cells are distribu...

However, this method reduces the blue light component, resulting in a change in the ratio of the RGB three colors. The reduction of the blue light component leads to an increase in the proportion of the two colors of red light and green light, making the overall picture yellowish. The field has changed, and the color display is biased
