OLED (Organic Light-Emitting Diode)
OLED is an emissive TV panel technology made from organic compounds that produce its own light rather than employ a backlight unit. These are used in TVs, computer, and mobile device displays. The key advantage OLED displays offer is an ability to produce a true black. Since there is no backlight, no light is produced when an OLED pixel is turned off and no light leakage can occur. Additionally, pixels can be individually controlled, so it will eliminate the halo effect (see separate definition).
