Abstract: Disclosed are a light source system and a display device, including: a first light source configured to emit first light; a second light source configured to emit second light; a wavelength conversion device configured to perform a wavelength conversion on the first light to obtain third light; a first optical splitter having a first area and a second area; and a first light combining device. The first optical splitter moves in timing sequence to make the first area and the second area be sequentially located on a preset light path. A side surface of the first optical splitter is configured to homogenize the first light and the second light that are emitted to the first light combining device; and the first light combining device is configured to guide the first light, the second light, and the third light to exit along a same light path to form illumination light.

Abstract: A projection screen and a processing method therefor, wherein the projection screen comprises, in sequence from the incident side of projection light, a diffusion layer, a microlens array and a substrate. The inner side of the substrate is provided with a Fresnel microstructure, and part of the surface of the Fresnel microstructure is provided with a reflecting layer while the remaining part of the surface is a light absorbing layer. The microlens array is used for focusing the projection light on the reflecting layer. The reflecting layer is used for reflecting projection light back to the field of view of viewers. Ambient light is mostly absorbed by the light absorbing layer. The settings of the structure and dimension of the microlens array enable the projection light to be only incident onto the reflecting layer of the Fresnel microstructure and the ambient light to be mostly absorbed by the light absorbing layer.

Abstract: A display apparatus and a display system are provided. The display apparatus includes: a narrow-spectrum light source configured to emit narrow-spectrum light in elliptical distribution; a reflection device including a reflection surface for reflecting the narrow-spectrum light to obtain to-be-modulated light; and a light modulation device configured to modulate the to-be-modulated light to obtain image light of an to-be-modulated image. The light modulation device includes a modulation surface configured to receive the to-be-modulated light, the modulating surface is at a preset angle to an optical axis of the to-be-modulated light such that the to-be-modulated light forms a circle light spot on the modulating surface. The narrow-spectrum light complying with the elliptical distribution is incident onto the light modulation device to form a circle light spot, thereby helping the light modulation device to emit image light in circular angular distribution, improving light effect and achieving better image display quality.

Abstract: A light source system includes an excitation light unit, a spectral filter unit, a scattering unit, and an excited-light unit. The excitation light unit is configured to emit excitation light. In an embodiment, the spectral filter unit reflects a portion of the excitation light to the scattering unit, the scattering unit scatters the same to generate a first light and a second light, and the spectral filter unit transmits the second light. The spectral filter unit also transmits another part of the excitation light to the excited-light unit, the excited-light unit emits excited light under the illumination thereof, and the spectral filter unit reflects the excited light, so that the spectral filter unit merges and emits the transmitted second light and the reflected excited light. The excitation light is thus split into two paths at the spectral filter unit, and finally emits light by combining excitation light and excited light.

Abstract: A reconfigurable mobile shelter system includes multiple shelter structures and a management system communicating with the shelter structures. The shelter structures are physically independent of each other, each located at a selected location, and configured to be moveable to another selected location without being disassembled and re-assembled. Each shelter structure has an access control subsystem and a user information collection module, and transmits user information to the management system. The management system, based on the received user information, determines whether to permit access by a user to a shelter structure and use of equipment inside, and transmits corresponding commands to the shelter structure. The management system also determines whether any shelter structure is to be moved to another selected location, and controls moving equipment to move them. The reconfigurable mobile shelter system may be used as a lodging facility, entertainment facility, office facility, education facility, meeting facility, etc.
