OLED Display

LED, an acronym for Light Emitting Diode, is a device that coverts electrical energy into light. LEDs can be used for a number of lightening purposes at home or workplace, and are also used for computers, DVD players, and televisions. OLED or Organic Light Emitting Diode is a modern advancement in LED technology, and has been introduced as a breakthrough in the display technology as well. The term organic in Organic Light Emitting Diode refers to the diode being made of organic material. Organic materials primarily refer to substances made of carbon.

An OLED is made of stacks of thin layers made of organic material, comprising a hole-injection layer, an emissive layer, a hole-transport layer, and an electron-transport layer. These are sandwiched between two electric conductors – an anode, which is transparent, and a metallic cathode. This is placed in between two glass plates – a bottom and a top plate. The top glass plate is known as seal, while the bottom glass plate is known as substrate. A bright eclectroluminescent light is produced by the emissive layer in the organic material when electric current of an appropriate voltage is applied to this system.

OLEDs used for television, computer monitor, or laptop screen display are more efficient than traditional of display technology. The advantages of OLEDs are numerous. OLEDs response faster, can allow for wide viewing angles and high brightness, and provides outstanding color reproduction. OLED can be incorporated into thin and lightweight designs given the nature of the technology used. They are also easier to fabricate than CRT, or cathode ray tube, display technology. OLEDs are better than LCD (liquid crystal display) technology as it can allow for viewing from different angles and do not need a backlight as the entire surface of OLED becomes a light source when electricity is applied, including all conductors and semiconductors. The power consumption and the drive voltage for OLED is also low compared to other similar innovations.

The most exceptional quality of OLED is perhaps the reproduction of color. OLED emits only pure colors when particular Pixels are stimulated by electrical current. Mounted directly onto a labeled circuit-board is the primary color matrix, organized in red, green, and blue Pixel. The ‘micro-cavity’ structure reduces the light interference from other sources, and improves the color contrast. Adjustments to the thickness of the organic layers can be made to produce strong lights of each color, and the use of a color filter to refine the color produces exceptional color purity.

It can also be used for a variety of purposes, including in personal computers, television screens, cell phones, laptops; in the lightening of wide areas; billboards and signs; in a number of communication and information appliances.

Only recently, a number of companies have started using OLED technology in their products. One such well-reputed electronics manufacturer is Sony, which has introduced the first organic LED television. With outstanding contrast, and color reproduction, high resolution and high brightness features, and incredibly slim design, he Organic Panel OLED Television is a 3 mm thin panel of marvelous picture quality, and is priced, quite appropriately, at $2499.99.

LG is also manufacturing televisions featuring the OLED technology. The manufacturer of Apple computers had been planning to introduce a new Netbook featuring OLED technology. This Netbook will be lighter and thinner, and will also provide high precision color display, all thanks to the OLED technology. However, the introduction of this Netbook has not been officially confirmed by Apple, yet.

Samsung is also rumored to be producing the first commercial OLED laptops by the end of 2010. The OLED is a breakthrough innovation in the contemporary market display technology. With all the advantages that it provides over other traditional forms of display, it has been suggested that OLED will become a norm like LCD in a matter of years.
