Display system and method

Abstract

The invention discloses a display system and method. The display system comprises a light source device, an optical processing component, a reflection device and an optical modulator. The light sourcedevice is used for emitting multiple light beams, the optical processing component is used for conducting light path adjustment for each light beam from the light source device so that the light beamis irradiated to the reflection device at a preset light angle, and the reflection device is used for reflecting the light beams from the optical processing assembly to the light modulator. The lightmodulator is used for modulating the light beams through the controllable units, so that display light that meets requirements is emitted. The display system has a deviation of the preset inclinationangle at a first direction or a second direction. The laser beam emitted by the light source device is further modulated through the light modulator, so that the display light which is used for generating more similar expected images is emitted. Easily generated errors are avoided, and the light spot dispersion degree difference on the spatial light modulator is smaller. The distortion and colordeviation in imaging of the display system are reduced, and the imaging quality and the display effect of the image are improved.

Description

technical field [0001] The present application relates to the fields of projection and display, and in particular to a display system and method. Background technique [0002] Existing displays mainly include a light source, a first photoelectric modulator, an imaging system, a second photoelectric modulator, and a projection screen. According to a certain image signal, two photoelectric modulators need to be used to control the light beam, and the structure is complex. and prone to errors. For the design of some displays, the internal reflection prism is used to change the direction of light propagation. Because the light cone angle expanded by the internal reflection prism is too large, the spherical aberration and astigmatism formed will cause the light spot on the photoelectric modulator to have a large difference in dispersion. Large, resulting in distortion and color deviation in the system imaging, poor color uniformity, and the quality of imaging display is not idea...
