Spatial Light Modulator - Electrically Addressed Spatial Light Modulator (EASLM)

Electrically Addressed Spatial Light Modulator (EASLM)

As its name implies, the image on an electrically addressed spatial light modulator is created and changed electronically, as in most electronic displays. EASLMs usually receive input via a conventional interface such as VGA or DVI input. They are commonly available at resolutions up to WUXGA (1920 × 1200). Unlike ordinary displays, they are usually much smaller (having an active area of about 2 cm²) as they are not normally meant to be viewed directly. An example of an EASLM is the Digital Micromirror Device at the heart of DLP displays or Electrically controlled birefringent LCoS Displays.
