Organic Light Emitting Diodes OLED

Page history last edited by PBworks 12 years, 4 months ago

Do power savings make up for short life?

 

OLED means Organic light emitting diode and is emerging as a leading next-generation technology for electronic displays and lighting. OLED can be used as display technology or as light source.

 

One of the great benefits of an OLED display over the traditional LCD displays is that OLEDs do not require a backlight to function. This means that they draw far less power and, when powered from a battery, can operate longer on the same charge. It is also known that OLED-based display devices can be more effectively manufactured than liquid-crystal and plasma displays. However, degradation of OLED materials have limited the use of these materials.

 

 

An organic light-emitting diode (OLED) is a special type of light-emitting diode (LED) in which the emissive layer comprises a thin-film of certain organic compounds. The emissive electroluminescent layer can include a polymeric substance that allows the deposition of very suitable organic compounds, for example, in rows and columns on a flat carrier by using a simple "printing" method to create a matrix of pixels which can emit different colored light. Such systems can be used in television screens, computer displays, portable system screens, advertising and information, and indication applications etc. OLEDs can also be used in light sources for general space illumination.

 

Why is OLED a next generation display technology?

 

Vibrant colors

High contrast

Excellent grayscale

Full-motion video

Wide viewing angles from all directions

A wide range of pixel sizes

Low power consumption

Low operating voltages

Wide operating temperature range

Long operating lifetime

A thin and lightweight form factor

Cost-effective manufacturability

computer screens
