Organic light-emitting diodes (organic light-emitting diode,oled) is a patented display technology developed by Kodak which uses organic polymeric materials as semiconductor (semiconductor) materials in light-emitting diodes.
OLED display technology is widely used in mobile phones, digital cameras, DVD players, personal digital assistants (PDA), notebook computers, car audio and television. OLED displays are thin and light because they do not use backlight. OLED displays also have a 160-degree widescreen view with operating voltages of two to 10 volts (the Volt, expressed in V).
OLED based technology has soft organic light-emitting display (flexible oled,foled), which may in the future make the highly portable, folding display technology possible.
