==SYSTEMS AND METHODS FOR LOCAL DIMMING IN MULTI-MODULATION DISPLAYS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18518082 titled 'SYSTEMS AND METHODS FOR LOCAL DIMMING IN MULTI-MODULATION DISPLAYS

==Simplified Explanation==

The abstract describes a patent application for a dual and multi-modulator projector display system. The system includes a light source, a controller, a first modulator rendering a halftone image, a blurring optical system, and a second modulator rendering a pulse width modulated image for projection.

* Explanation of the patent/innovation:
- Light source provides illumination for the system.
- Controller manages the operation of the modulators.
- First modulator creates a halftone image of the input image.
- Blurring optical system blurs the halftone image with a Point Spread Function.
- Second modulator renders a pulse width modulated image for projection.

* Potential applications of this technology:
- High-quality projector displays for home entertainment systems.
- Advanced visualization systems for medical imaging.
- Enhanced display solutions for virtual reality and augmented reality applications.

* Problems solved by this technology:
- Improved image quality through halftone rendering and modulation techniques.
- Correcting misalignment between modulators for accurate image projection.
- Continuous calibration for long-term image enhancement.

* Benefits of this technology:
- Enhanced image sharpness and clarity.
- Versatile display capabilities for various applications.
- Long-term reliability and performance consistency.

* Potential commercial applications of this technology:
- Consumer electronics industry for high-end projectors.
- Healthcare sector for advanced medical imaging displays.
- Entertainment industry for immersive visual experiences.

* Possible prior art:
- Prior art may include traditional projector display systems with single modulators.
- Previous patents related to image rendering and modulation techniques in display technology.

Questions:

1. How does the blurring optical system improve the final projected image quality?
2. What specific industries or sectors could benefit the most from this dual and multi-modulator projector display system technology?


==Original Abstract Submitted==

Dual and multi-modulator projector display systems and techniques are disclosed. In one embodiment, a projector display system comprises a light source; a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs said halftone image with a Point Spread Function (PSF); and a second modulator receiving the blurred halftone image and rendering a pulse width modulated image which may be projected to form the desired screen image. Systems and techniques for forming a binary halftone image from input image, correcting for misalignment between the first and second modulators and calibrating the projector system—e.g. over time—for continuous image improvement are also disclosed.
