LEC – Light emitting capacitor is an electroluminescent device in which the active layer is an electroluminescent polymer – a polymer which discharge photons when an electrical current is gone through it. The polymers utilized are conjugated polymers, which means the synthetic and electronic of the material permit it to act as an ionic conductor, giving it the electronic and optical properties of a semiconductors.
LECs give multiple advantages – They are perfect with economical manufacturing process, reduce the requirement of visible anode, and are autonomous of the difference in the work capacity of the electrodes.
Future expand on the working, development and utilization of LECs.
The active polymer layer comprises of electronic and ionic conductors. This layer is in the middle of the two cathodes. At the point when an electric charge is connected on the anodes, electrons and openings are discharged and they aggregate around the polymer layer. The recombination of the electron gap sets causes the polymer layer to discharge light.
The polymer layer of the LEC is sandwiched between the two anodes. The polymer layer is an ionic leading layer, made of conjugated polymers like poly (ethylene oxide), MEH-PPV, and so on.
Lately, various LECs have been produced having distinctive designs as recorded written below:
Bilayer LECs – fit for radiating distinctive hues at forward and invert inclination
Solidified p-i-n intersection LECs – fit for working like diodes
Some of the typical applications of LECs are given below:
- Information displays
- High-brightness lighting
- Flexible flat-panel displays
