With crazily low price for flat panel TVs, we are hearing OLED technology more these days.
SO what is OLED compare to LED?
Using the popular flat screen TV as an example, we have the following;
1. LEDs lighting devices are generally a solid state semiconductor or object where people can see and touch. (We all probably imagine a diode to be a solid state item.)
2. OLEDs are organic compounds that generally human eye is unable to detect unless put under a chemically treated film. (Recall your chemistry lesson in secondary school where you mix elements to derive SALT e.g. copper sulphate etc...)
LED is just an abbreviation for 'light emitting diode'. It does not refer to the state matter (Solid, liquid or gas) in the above comparison, though we generally take it to be a solid object.
The power of OLED;
Refer to our post on 31/10/14 where it can be applied on the cabin of an airplane that mimics the night sky outside.
OLED being organic compound is so thin (Thin as a plastic film, since it is sandwich between) that it can eliminate a hugh problem when it comes to creating space for your lights. Current LED strips are about 2-3mm in height. OLED is definitely less than 1mm.
OLED lights up when electricity is pass through it similar to LEDs. In relation to TVs, OLED is the display itself while LED acts as a lighting instrument for our LCD screen.
The above points are based on personal research and should not be relied upon solely as definitive. We stand to be corrected and would love to bring the discussion forward with whoever is interested.
