Imaging Technology

• DLP (Digital Light Processing)
  • How Does It Work?
    • Small mirrors fixed on a chip called a Digital Micromirror Device (DMD) reflect light toward the screen while a color wheel creates sequential color.
  • Where Is It Used?
    • You’ll often find DLP projectors in movie theaters.
  • What Are Its Advantages?
    • Sharp image quality
    • High Contrast Ratios
    • Can handle fast motion
    • Great for 3D
    • Less maintenance than LCD
  • What Are Its Disadvantages?
    • Can’t render rich blacks
    • Poor viewing range requires careful placement
    • Can create a “rainbow” effect

 

• LCD (Liquid Crystal Display)
  • How Does It Work?
    • Dichroic mirrors and red, green and blue liquid crystal panels are used to project an image onto the screen.
  • Where Is It Used?
    • Many Projectors and TVs use LCD technology.
  • What Are Its Advantages?
    • Better color saturation
    • Can render blacks very well
    • Less maintenance
    • Better viewing range
    • Affordable
  • What Are Its Disadvantages?
    • Noisy
    • Cannot accommodate LED or laser lights
    • LCD is brighter than DLP
    • Requires more maintenance, such as cleaning filters
