Display device

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.

Blue light-blocking structure and manufacturing method thereof, display device and operation method thereof

The present disclosure provides a backlight module, a display apparatus and an illumination apparatus. The backlight module includes: a light guide plate; a light emitting diode arranged above the light guide plate; an optical film layer arranged above the light emitting diode; a film of material with a polarization orientation arranged above the optical film layer; a liquid crystal cell arranged above the film of material; and a polarizer arranged above the liquid crystal cell. The liquid crystal cell includes an upper electrode and a lower electrode and a liquid crystal layer between the upper electrode and the lower electrode and the liquid crystal layer is capable of changing polarization state of a light passing through the liquid crystal cell, by the control of a voltage applied between the upper electrode and the lower electrode.
