PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240210807 titled 'PROJECTOR
The abstract of the patent application describes a projector that includes a light source, a lens group, a light-incident-side polarizer, a light modulator, a light-exiting-side polarizer, and a projection lens. The light modulator has sub-pixels for blue, green, and red light, while the lens group consists of two lenses with positive power and convex surfaces.
- Light source, lens group, polarizers, light modulator, and projection lens are key components of the projector.
- Light modulator has sub-pixels for blue, green, and red light, allowing for color modulation.
- Lens group consists of two lenses with positive power and convex surfaces, aiding in beam parallelization.
Potential Applications: - Home entertainment systems - Business presentations - Educational settings
Problems Solved: - Enhanced image quality - Efficient light modulation - Improved color accuracy
Benefits: - Crisp and clear projection images - Accurate color representation - Versatile applications in various settings
Commercial Applications: Title: Advanced Projection Technology for Enhanced Visual Experiences This technology can be used in theaters, conference rooms, classrooms, and home theaters to provide high-quality visual experiences.
Prior Art: Further research can be conducted on similar projector technologies and advancements in light modulation and lens design.
Frequently Updated Research: Stay updated on advancements in light modulation techniques, lens technology, and projector design for improved projection quality.
Questions about the Technology: 1. How does the lens group contribute to the overall performance of the projector? 2. What are the potential limitations of the light modulator in this projector design?
Original Abstract Submitted
a projector includes a light source, a lens group that parallelizes the beam output from the light source, a light-incident-side polarizer that transmits the beam having exited out of the lens group, a light modulator that modulates the beam having passed through the light-incident-side polarizer to form a projection image, a light-exiting-side polarizer that transmits the beam modulated by the light modulator, and a projection lens that projects the beam having passed through the light-exiting-side polarizer. the light modulator includes first sub-pixels on which blue light is incident, second sub-pixels on which green light is incident, and third sub-pixels on which red light is incident. the lens group includes two lenses each having positive power. the two lenses each have a convex surface.
