    摘要： A light conversion structure applied to a display device, and a backlight module, a color filter substrate, and a display device including the light conversion structure are provided. The light conversion structure includes a light filter structure (100) including a first optical film layer (110) and a second optical film layer (120) which are alternately arranged and attached to each other in a total number of N, N is an even number, one of a surface (111) of the first optical film layer (110) far away from the second optical film layer (120) and a surface (121) of the second optical film layer (120) far away from the first optical film layer (110) is a light incident surface (1001) of the light filter structure (100), and the other one is a light-exiting surface (1003). A part of the incident light (101) of first color that is reflected by the light incident surface (1001) is a first reflected light (102), a part of the incident light (101) of first color that is reflected by an interface (1002) between the first optical film layer (110) and the second optical film layer (120) is a second reflected light (103), and an optical path difference between the first reflected light (102) and the second reflected light (103) is an integer multiple of a wavelength of the incident light (101) of first color. The light conversion structure can reflect a part of the incident light of first color to allow the incident light of first color to be reused, thereby improving a utilization of a light-emitting material in the display device.

    摘要： Disclosed are a near-eye display device and a near-eye display system. The excitation light source structure provides excitation light to the first waveguide structure, and the outgoing coupling grating structure corresponding to the first waveguide structure receiving the excitation light may be further irradiated by the excitation light, and be excited and output the light with a pixel color corresponding to the first waveguide structure. That is, the outgoing coupling grating structure corresponding to the first waveguide structure receiving the excitation light can derive the light with the corresponding pixel color emitted by the projection-based display, and be excited by the excitation light emitted by the excitation light source structure to output light with a pixel color corresponding to the first waveguide structure.

    摘要： A display system and a display control method of the display system are provided. The display system includes a display device, at least two layers of liquid crystal cells on a light-emitting side of the display device, and a controller device. The display device is configured to display a display picture; the at least two lavers of liquid crystal cells are configured to control an exit angle of light of the display picture; the controller device is configured to control positions and/or widths of light-transmitting regions and light-shielding regions of each layer of the liquid crystal cells to control a display mode of the display picture. The display system can control the positions and widths of the light-transmitting regions and the light-shielding regions formed on each liquid crystal cell according to actual needs, thereby realizing switching among various display modes.
