Study Notes

Projector Types

Ultra-short Throw: Throw ratio between 0.16 to 0.38, designed for very close projection to the screen.
Short Throw: Throw ratio ranges from 0.4 to 0.8, suitable for smaller rooms.
Standard Throw: Throw ratio from 1 to 2.56, typically used in larger settings.
Long Throw: Throw ratio spans 2.56 to 10.11, ideal for projecting over longer distances.

Projection Technologies

Two main types of projection technologies: 3LCD and DLP (Digital Light Processing).
3LCD uses three separate LCD chips for color and image production.
DLP utilizes a single chip for image processing, often leading to more compact designs.

Projector Basics

Projection Technology: Predominantly 3LCD for brighter images and better color.
Light Source: Available in Lamp or Laser options.
Native Resolution: Varies from XGA (1024x768) to WUXGA (1920x1200) and up to 4K for high-definition images.
Light Source Life:
- Normal lifespan:
  - Lamp: 4,000 to 8,000 hours.
  - Laser: 20,000 hours.
- Eco mode lifespan:
  - Lamp: 7,000 to 17,000 hours.
  - Laser: 30,000 hours.
Screen Size:
- Standard throw projectors can accommodate image sizes from 30 inches to 1000 inches.
- Ultra-short throw projectors are typically used for image sizes between 60 inches and 160 inches.
Brightness Levels:
- Lamp projectors: 2,600 to 5,500 Lumens.
- Laser projectors: 1,000 to 30,000 Lumens.
- Both types offer a white light output and color light output in the same range.
Contrast Ratio:
- Lamp projectors: Typically between 15,000:1 and 16,000:1.
- Laser projectors: Up to 50,000:1, resulting in more vivid images.
Connectivity Options: Include VGA, HDMI, USB Type A and B, Wired LAN, optional Wireless (via ELPAP10/ELPAP11), Stereo Mini Jack, RS-232C, and HDBaseT.

Additional Information

DLP is a registered trademark of Texas Instruments, highlighting its proprietary technology in digital projection.
