  • 2009 – An OLED thin film device integrated into a steering wheel. See full story
  • 2009- Multiple-line address for passive –matrix OLED. See full story

OLED (organic light emitting diode) displays are the next generation of emissive technology. These displays are composed of self-luminous pixels and require no backlights, incorporating 5-6 thin film layers to emit light. The technology provides clear, bright, full-motion image display that can be viewed from a very wide angle. In addition, OLED displays offer fast response times, high brightness levels in a variety of lighting conditions, low power consumption, and thin design options.

OLED Advantages Over LCD

  • Response time / << ms
  • Viewing Angle
  • Performance at low temperature
  • High Image Quality in passive drive

OLED Advantages Over VFD

  • Fine resolution / Pixel pitch and Space
  • Appearance / Visibility of electrode structure
  • Design Flexibility and Color image
  • Pb Free
