 How does an OLED monitor work?

Correct Answer

verifed

verified

An OLED (Organic Light-emitting Diode) monitor uses a thin LED layer or film between two grids of electrodes and does not use backlighting. It does not emit as much light as an LCD monitor does, and, therefore, can produce deeper blacks, provide better contrast, work in darker rooms, and use less power than can an LCD monitor. On the other hand, LED monitors give less glare than OLED monitors. OLED screens are used by digital cameras, camcorders, mobile devices, and other small portable electronic devices. OLED monitors are just now appearing for desktop systems.
