SCANNING PROJECTOR PIXEL PLACEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18035389 titled 'SCANNING PROJECTOR PIXEL PLACEMENT

Simplified Explanation

The patent application describes a system for displaying graphical content using light beams and an optical element. The system modulates the intensity of the light beams and redirects them along a scan path on a projection surface.

  • The system receives or generates timing information for multiple locations on the projection surface.
  • It emits one or more light beams with different intensities.
  • The light beams are redirected along a scan path that includes some of the multiple locations on the projection surface.
  • During the redirection, the intensity of each light beam is modulated according to the timing information.
  • This modulation allows the system to display pixels of an image at each of the multiple locations on the projection surface.

Potential Applications

  • Projection systems for movies, presentations, or entertainment purposes.
  • Augmented reality or virtual reality displays.
  • Advertising displays or signage.
  • Gaming or interactive displays.

Problems Solved

  • Provides a method for displaying graphical content with high precision and accuracy.
  • Allows for the creation of dynamic and interactive displays.
  • Enables the projection of images onto curved or irregular surfaces.

Benefits

  • Improved image quality and resolution.
  • Enhanced user experience with interactive and immersive displays.
  • Flexibility to project onto various surfaces and shapes.


Original Abstract Submitted

Systems, devices, and techniques are provided for displaying graphical content by modulating an intensity of one or more emitted light beams while redirecting those emitted light beams along a scan path that includes multiple locations of a projection surface Timing information that specifies timing values associated with each of multiple locations on a projection surface of an optical element is received or generated. One or more light beams that each have a respective intensity are emitted, and redirected along a scan path that includes at least some of the multiple locations. During the redirection of the one or more emitted light beams, the respective intensity of each of the one or more emitted light beams is modulated in accordance with the timing information to display one or more pixels of an image at each of the at least some multiple locations.
