OLED displays use organic compounds that emit light when exposed to an electric current. They are brighter, have better contrast, offer wider viewing angles, use less power, and provide faster response times than liquid crystal displays. OLED screens' thickness is a third of that of LCDs, since they don't need a back-light, and that makes them a good fit for portable electronics devices.
==Rationale==
Unlike LCDs, which require backlighting, OLED displays are "emissive" devices, meaning they emit light rather than modulate transmitted or reflected light.
