OLED Technology
[attachment=64978]
OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity.
OLEDs can provide brighter and sharper displays on electronic devices and use less power than conventional light-emitting diodes (LEDs) or liquid crystal displays (LCDs) used today.
The color of the light depends on the type of organic molecule in the emissive layer.
Manufacturers place several types of organic films on the same OLED to make color displays.
The intensity or brightness of the light depends on the amount of electrical current applied: the more current, the brighter the light
PMOLEDs are easy to make, but they consume more power than other types of OLED, mainly due to the power needed for the external circuitry.
PMOLEDs are best suited for small screens such as those you find in cellphones, PDAs and MP3 players.
Even with the external circuitry, passive-matrix OLEDs consume less battery power than the LCDs that currently power these devices
The plastic, organic layers of an OLED are thinner, lighter and more flexible than the crystalline layers in an LED or LCD.
Because the light-emitting layers of an OLED are lighter, the substrate of an OLED can be flexible instead of rigid. OLED substrates can be plastic rather than the glass used for LEDs and LCDs.
OLEDs are brighter than LEDs. Because the organic layers of an OLED are much thinner than the corresponding inorganic crystal layers of an LED, the conductive and emissive layers of an OLED can be multi-layered. Also, LEDs and LCDs require glass for support, and glass absorbs some light. OLEDs do not require glass.
Research and development in the field of OLEDs is proceeding rapidly and may lead to future applications in heads-up displays, automotive dashboards, billboard-type displays, home and office lighting and flexible displays.
Because OLEDs refresh faster than LCDs almost 1,000 times faster a device with an OLED display could change information almost in real time. Video images could be much more realistic and constantly updated.
