They are optical effects to convert the sunlight or light from any other source to graphic form. Liquid crystal display is an example.
A nonemissive display is a device that presents information by changing the ambient-light pattern at the observer, or in some special cases by altering the transmission of externally generated light through the device. … Externally generated light usually results in a projection display.

Non-Emissive Display: The Non-Emissiv Emissive displays are devices that convert electrical energy into light; where the image is produced directly on the screen. Non-emissive displays use optical effects to convert sunlight into graphical patterns and shapes; where the light is produced behind the screen and the image is formed by filtering this light.e displays use optical effects to convert sunlight or light from some other source into graphics patterns. Examples are LCD (Liquid Crystal Device). Plasma-Panels are also called as Gas-Discharge Display.

A nonemissive display is a device that presents information by changing the ambient-light pattern at the observer, or in some special cases by altering the transmission of externally generated light through the device. The term passive display is also used for a nonemissive display to distinguish it from active or light-emitting technologies. Externally generated light usually results in a projection display. Unfortunately, there is no commonly accepted name for the technologies which are the subject of this chapter, other than terms that contrast them with light-generating technologies. The lack of a forceful-sounding name has not prevented nonemissive displays from playing an important role in information display. As will be shown, they are becoming dominant in applications that require battery operation and sunlight viewing.

Advantage:

  1. No refreshing is needed.
  2. High Resolution
  3. Cost is very less
    Disadvantage:
  4. It is not possible to erase the selected part of a picture.
  5. It is not suitable for dynamic graphics applications.
  6. If a part of picture is to modify, then time is consumed
