PROJECTOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522488 titled 'PROJECTOR
Simplified Explanation
The projector described in the patent application includes a light modulation section with unit pixels segmented by a black matrix, a projection system, and a pixel shifting device that shifts the optical path of image light output from the light modulation section. One unit pixel is set as a reference pixel, and the pixel shifting device superimposes the image light output from the reference pixel at a shifted display position on the region surrounding the reference pixel without overlapping with adjacent unit pixels.
- Explanation of the patent:
- Projector with pixel shifting device for precise image display without overlap.
- Potential applications:
- High-resolution projectors for home theaters, classrooms, and conference rooms.
- Problems solved:
- Eliminates overlap of image light output from adjacent pixels for clear and accurate display.
- Benefits:
- Improved image quality, sharper details, and enhanced viewing experience.
- Potential commercial applications:
- Projection systems for entertainment venues, educational institutions, and corporate settings.
- Possible prior art:
- Similar pixel shifting technologies used in high-end projectors for improved image quality.
- Unanswered Questions:
- How does the pixel shifting device ensure precise alignment of the image light output from the reference pixel?
The patent abstract does not provide specific details on the mechanism used by the pixel shifting device to accurately superimpose the image light output at the shifted display position.
- What are the potential limitations or drawbacks of implementing this pixel shifting technology in projectors?
The abstract does not address any potential challenges or limitations that may arise from incorporating the pixel shifting device in projectors, such as cost implications or compatibility issues with existing projection systems.
Original Abstract Submitted
A projector according to an aspect of the present disclosure includes a light modulation section that has a pixel region containing a plurality of unit pixels segmented by a black matrix, a projection system, and a pixel shifting device that shifts the optical path of image light output from the light modulation section. One of the plurality of unit pixels in the pixel region is set as a reference unit t pixel, and the pixel shifting device superimposes the image light output from the reference unit pixel at a shifted display position on the region corresponding to the black matrix and surrounding the reference unit pixel at a reference display position in such a way that the image light does not overlap with other unit pixels adjacent to the reference unit pixel out of the unit pixels.
