This approach is large and bulky, and cannot be imple-
mented in most hand held equipment. Zywyn now offers
low power single chip driver circuits specifically designed
to drive small to medium sized electroluminescent panels.
All that is required is one external inductor and capacitor.
Electroluminescent backlighting is ideal when used with
LCD displays, keypads, or other backlit readouts. Its main
use is to illuminate displays in dim to dark conditions for
momentary periods of time. EL lamps typically consume
less than LEDs or bulbs making them ideal for battery
powered products. Also, EL lamps are able to evenly light
an area without creating “hot spots” in the display. The
amount of light emitted is a function of the voltage applied
to the lamp, the frequency at which it is applied, the lamp
material used and its size, and lastly, the inductor used.
There are many variables which can be optimized for
specific applications.
