PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240288761 titled 'PROJECTOR
The abstract describes a projector with a separation optical system that separates outgoing light into different colored light beams for modulation and projection.
- Separation optical system with a first dichroic mirror for separating light into colored beams.
- First and second light modulation elements for modulating the colored light beams.
- Reflecting mirror to direct the modulated light beams towards the projection system.
- Reduction optical system to reduce the luminous flux width of the modulated light beams.
- Color combining prism to combine the modulated light beams for projection.
Potential Applications: - This technology can be used in home theater projectors, business presentations, and educational settings. - It can also be applied in large venue projectors for events and concerts.
Problems Solved: - Provides a more efficient way to modulate and project colored light beams. - Enhances the quality and brightness of projected images.
Benefits: - Improved image quality and color accuracy. - Energy-efficient modulation and projection system. - Enhanced viewing experience for audiences.
Commercial Applications: Title: Advanced Projection Technology for Enhanced Viewing Experiences This technology can be commercialized in the consumer electronics industry for the development of high-quality projectors for various applications. It can also be utilized in the entertainment industry for large-scale projection needs.
Questions about the technology: 1. How does the reduction optical system contribute to the overall performance of the projector? - The reduction optical system helps to improve the sharpness and clarity of the projected images by reducing the luminous flux width of the modulated light beams.
2. What are the advantages of using a color combining prism in the projector system? - The color combining prism allows for the seamless integration of the modulated colored light beams, resulting in vibrant and accurate color reproduction on the projection screen.
Original Abstract Submitted
a projector includes a separation optical system including a first dichroic mirror for separating outgoing light into a first colored light beam as a blue light beam and another colored light beam, a first light modulation element for modulating the first colored light beam, a second light modulation element for modulating the other colored light beam, a reflecting mirror for reflecting the first colored light beam from the first dichroic mirror, toward the first light modulation element, a reduction optical system for reducing a luminous flux width of the first colored light beam modulated by the first light modulation element, and a color combining prism. the effective area of the first light modulation element is larger than the effective area of the second light modulation element.
