The display device A display device includes a light source assembly, sub-pixels of multiple colors; The grating period of the fiber grating, the photoluminescent material is arranged at the light outlet corresponding to the first fiber grating, and the light source component is used to provide excitation light for the light inlet of the first fiber grating of each sub-pixel, wherein the The exciting light can make the corresponding photoluminescent material excited to emit the light of the corresponding color of the sub-pixel. The display device realizes grayscale control of sub-pixels.

Description

technical field [0001] The technical field of design and display of the present invention, more specifically, relates to a display device and a display method. Background technique [0002] Existing display devices generally include liquid crystal display devices and light emitting diode display devices. In the liquid crystal display device, the change of the voltage difference between the pixel electrode and the common electrode leads to the change of the state of the liquid crystal molecules between the two, which in turn leads to the change of the polarization direction of the light, combined with the selection of the polarization direction of the light by the polarizer, Thereby achieving different gray scales. In a light emitting diode display device, different gray scales are realized by controlling the magnitude of the current of the light emitting diode. The display principles of existing display devices are limited, and it is necessary to provide more display devic...
