OLED screens and microdisplays are appearing in an increasing number of higher-end cameras, such as the Samsung NX200.

 OLEDs (or Organic Light Emitting Diodes) are thin, light-emitting devices, made by placing a series of organic thin films between two conductors. 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. OLED displays have greater viewing angles, allowing more flexible use of the camera, both for shooting and reviewing images, or showing them to others.




Challenges for OLED
For touch displays, Samsung developed the Super AMOLED technology which embeds the touch sensor into the OLED panel. Some companies are actually using white OLED sub pixels behind a color filters layer. OLED screens are becoming increasingly common on enthusiast cameras. During the world's largest electronics show, CES 2012, OLED was the most talked about technology.
