OLED

Technology overview

OLED (Organic Light-Emitting Diode) is a self-emissive display in which current flows through a thin organic film between two electrodes,
and light is emitted as electrons and holes recombine.

With fast response times, wide viewing angles, ultra-thin structures, and outstanding image quality, OLED delivers the key attributes required for
next-generation displays beyond LCD technology.

Because OLED does not require a backlight, it offers excellent visibility while enabling flexible and ultra-thin designs.
Its versatility also allows expansion into a wide range of form factors, including transparent displays.

  • Self-emissive structure

    High visibility and deep contrast without a backlight.

  • Ultra-thin, lightweight design

    Enables thinner, lighter displays suited to a wide range of designs.

  • Fast response

    Quick transitions with minimal motion blur for crisp video reproduction.

  • Wide viewing angle

    Stable color and luminance from virtually any viewing angle.
