If we compare an LED and OLED television screens, it is quite clear that the LG OLED TV has vibrant colours and better image reproduction quality than the other. The answer to this difference is display technology! The LG TV is based on the most advanced display technology ― OLED and other TVs are on IPS LCD technology. Let’s learn in detail about OLED technology.
An organic light-emitting diode OLED, also known as organic electroluminescent (organic EL) diode,is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current.Watch video from Lesics:
This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. The organic molecules are electrically conductive as a result of delocalization of pi electrons caused by conjugation over part or all of the molecule.

These materials have conductivity levels ranging from insulators to conductors, and are therefore considered organic semiconductors. The highest occupied and lowest unoccupied molecular orbitals (HOMO and LUMO) of organic semiconductors are analogous to the valence and conduction bands of inorganic semiconductors./wikipedia
