| 摘要 |
This invention relates in general to methods and systems of a projection display that can be used in 4 display modes: (A) as a rear-projection 2D display, (B) as a volumetric 3D (V3D) display, (C) as an auto-stereoscopic 3D (as3D) display, or (D) as a projector. Conversion among the 4 display modes requires only 1 to 3 actions of adjustment by the user. The system can further contain an integrated touch pad for direct, barrier-free interaction with 2D, as3D or V3D images. The illumination and projection of the SLM is converted between a sub-panel mode and a full-panel mode. By using the sub-panel illumination/projection mode, the system can operate in V3D, 2D and as3D modes. By using the full-panel mode, the system can operate in 2D and projector modes.
