Abstract
A blue light-blocking structure and manufacturing method thereof, a display device and an operation method thereof are provided. The blue light-blocking structure includes a first transparent dielectric layer, a second transparent dielectric layer and an electro-refractive index adjusting layer. The second transparent dielectric layer is provided on a side of the first transparent dielectric layer. The electro-refractive index adjusting layer is provided between the first transparent dielectric layer and the second transparent dielectric layer. The electro-refractive index adjusting layer is configured to change the refractive index to the blue light transmitted through the electro-refractive index adjusting layer under the action of an electrical field applied between a first side of the electro-refractive index adjusting layer near the first transparent dielectric layer and a second side near the second transparent dielectric layer.
