OLED, or Organic Light-Emitting Diode, displays are able to deliver sharper and brighter images than LCDs, while also using less power. Unlike an LCD, which requires a backlight, OLED screens can emit their own light. This allows OLED screens to display brighter, sharper images and text, and to offer better viewing angles. It also means that OLED screens are thinner and consume less power than their LCD counterparts.
OLED screens also offer faster refresh rates than LCDs, so they can deliver smoother video playback. But there are a few drawbacks to OLED displays. For one, the organic materials used to make them have a more limited lifetime than the components of other display types. OLED screens also have the potential to be more easily damaged by water or other liquids. Also, when viewed in direct sunlight, the images on an OLED display are not as bright as what you'd see on an LCD.
