OLEDs (or Organic Light Emitting Diodes) are thin, light-emitting devices, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLED are thin, efficient and bright – and can be used to make displays and white lighting panels.
OLED advantages
Unlike LCD displays, OLEDs do not require a backlight. In an OLED display each ‘pixel’ is a small light emitting diode (or, more commonly, three: red, blue and green). The biggest advantages of OLED displays are the things that photographers are most likely to appreciate.
Challenges for OLED
For touch displays, Samsung developed the Super AMOLED technology which embeds the touch sensor into the OLED panel. OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. OLEDs can be used to make displays and lighting. Until recently, LCD was the only technology used for digital camera displays. This is beginning to changes with the emergence of Organic Light Emitting Diode (OLED) technogy.
