What is an OLED display?
An OLED display uses a new technology called OLED (Organic Light Emitting Diodes). OLED screens are brighter, more efficient, thinner and feature better refresh rates and contrast than LCD or Plasma.
OLEDs are made by placing thin films of organic (carbon based) materials between two conductors. When an electrical current is applied, a bright light is emitted. Since the OLED materials emit light, a backlight is not required (unlike LCDs).
OLEDs in mobile phones
Mobile phones that boast OLED screens are rapidly becoming more prevalent, with over 500 million AMOLED screens annually - mostly to satisfy demand from mobile phones. Samsung has been using AMOLEDs in its high-end phones for many years, and most phone makers are also adopting OLED displays (including Apple, LG, Xiaomi, Huawei, Oppo, Vivo, Lenovo, Motorola, and others).
OLED displays are advancing quickly, and today smartphone AMOLED displays outperform LCDs in all parameters - except the price which is still at a premium.
