(Organic Light Emitting Device, Organic Light Emitting Diode) A display technology that offers bright, colorful images with a wide viewing angle, low power, high contrast ratio and fast response time for sports and action movies. The OLED technology differs greatly from the screens in plasma and LCD/LED TVs. However, OLED more resembles plasma because the colors are intrinsically generated (see LCD vs. plasma). Because OLEDs do not require backlights, the screens can be ultra thin. OLEDs also have great potential for general lighting (see WOLED). Passive and Active OLEDs Passive matrix OLEDs appeared in cellphones and MP3 players in the 1990s, and active matrix OLEDs followed in 2003. Four years later, Sony introduced the first active matrix OLED TV, but with only an 11" screen. However, significant progress was made in the next five years, and LG and Samsung debuted 55" OLED TVs in 2012. Extremely Versatile OLEDs can be transparent, enabling them to function in heads-up displays and as window shades that react to sunlight. OLED's color, speed, thinness, transparency and flexibility make it the display technology of the 21st century. See PHOLED, AMOLED, TOLED, OLED lighting and LED.
