PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18393831 titled 'PROJECTOR
The abstract describes a projector with a light source, lens group, polarizers, light modulator, and projection lens. The light modulator includes 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 includes 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 and projection.
Potential Applications: - Home theater systems - Business presentations - Educational settings
Problems Solved: - Enhanced image quality - Color accuracy - Brightness control
Benefits: - Crisp and clear projections - Accurate color reproduction - Versatile applications
Commercial Applications: Title: Advanced Projector Technology for Enhanced Visual Experiences This technology can be used in various commercial settings such as cinemas, conference rooms, and classrooms to provide high-quality visual presentations and entertainment experiences.
Questions about Projector Technology: 1. How does the lens group contribute to the overall performance of the projector? The lens group helps to parallelize the beam output from the light source, leading to improved image quality and clarity.
2. What role do the sub-pixels in the light modulator play in color modulation? The sub-pixels in the light modulator allow for precise control over the intensity of blue, green, and red light, resulting in accurate color reproduction.
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.
