Abstract
(EN)
A display device, comprising: a light-emitting device (1) and a light adjustment layer (2); the light adjustment layer (2) is located at a light emission side of the light-emitting device (1), the light-emitting device (1) is used for generating and emitting light in a visible light wavelength range; the light adjustment layer (2) is configured to block, when an external stimulus is applied, the passing through of light having a wavelength within a part of wavelength range of blue light, and to allow, when the external stimulus is removed, the passing through of the light having a wavelength within a part of wavelength range of blue light, the light adjustment layer (2) comprising a responsive photonic crystal.
