Electronic Displays:- Electronic displays are solid state displays which use a phosphor to emit light in the presence of an electric field. Phosphors used are usually yellow-orange or green.
Advantages:-
* Flat panel
* Bright, light emitting mono displays
Disadvantages:-
* 150V+ operating voltages
* Color panels difficult to make
* Development largely overtaken by PDPs
Light Emitting Diode (LED):- Light Emitting Diode (LED) are photon emitting semiconductors which emit light due to the injection electroluminescence effect. The wavelength of the emitted light varies primarily due to the choice of semiconductor materials used, and is commonly in visible spectrum or infrared.
Advantages:-
* Lowest cost red or green emissive indicator
* Available in very small sizes
* Very bright versions available (higher cost)
* Red and green types work from 3V supply
Disadvantages:-
* LED is point source, so light shaping required to make segment shapes
* White and blue LEDs expensive, need >3.6V supply
* Can have narrow viewing angle
* Color and efficiency vary with temperature and curren
* Care required to achieve 50 khrs+ life
