A display system and method

Abstract

The application discloses a display system and method, including a light source device, an optical processing component, a reflection device, and a light modulator. The light source device is used to emit multiple beams of light; the optical processing component is used to adjust the optical path of each beam of light from the light source device so that it is irradiated to the reflection device at a preset light cone angle; the reflection device is used to convert the light from the optical processing component The light beam is reflected to the light modulator; the light modulator is used to modulate the light beam through each controllable unit so as to emit display light that meets requirements. The deviation between the first direction or the second direction of the display system and the horizontal direction has a preset inclination angle. The laser beam emitted by the light source device of the present invention is further modulated in the light modulator, so as to emit display light that is more similar to the desired image, avoiding errors that are prone to occur, and the difference in the dispersion degree of the light spot on the spatial light modulator is smaller, The distortion and color deviation in the imaging of the display system are reduced, and the imaging quality and the display effect of the picture 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...
