Because OLED elements individually emit light that are directly displayed on the screen, high brightness levels can be achieved.
Energy Efficiency

OLED technology delivers a more efficient means of utilizing light, which is generated by the organic material itself instead of an always on backlight; also, when elements are in their “off” state, they consume no power whatsoever.
OLED Story

What’s so great about OLED– Lots! Blazing fast response times, wide viewing angles, exceptional color reproduction, outstanding contrast levels, and high brightness. The nature of its technology lends itself to extremely thin and lightweight designs along with the ability to use it in a variety of different applications. OLED is the holy grail of TV display technologies!
What is OLED–

OLED stands for Organic Light Emitting Diode. The “organic” in OLED refers to organic material. Carbon is the basis of all organic matter. Examples of carbon-based substances include sugar, wood and the majority of plastics. The “LED” stands for “Light Emitting Diode” and describes the process of converting electric energy into light. There are two types of OLED — small molecule OLED and polymer OLED. Sony uses the small molecule type because it has a longer lifespan.
How does OLED work–

A layer of organic material is sandwiched between two conductors (an anode and a cathode), which in turn are sandwiched between a glass top plate (seal) and a glass bottom plate (substrate). When electric current is applied to the two conductors, a bright, electro-luminescent light is produced directly from the organic material.
How is color created–

OLED has more control over color expression because it only expresses pure colors when an electric current stimulates the relevant pixels. The OLED primary color matrix is arranged in red, green, and blue pixels, which are mounted directly to a printed circuit board. Each individual OLED element is housed in a special “micro-cavity” structure designed to greatly reduce ambient light interference that also works to improve overall color contrast. The thickness of the organic layer is adjusted to produce the strongest light for each of the colors — red, green and blue - used to render the color picture. The three colors are further refined by a color filter, which purifies each color without the need for a polarizer, rendering outstanding color purity.
What’s next for OLED–

Sony established a milestone with the introduction of the industry’s first Organic Light Emitting Diode (OLED) television, the XEL-1. This 11” diagonal desktop color television is just the first step Sony is taking in the world of OLED televisions. Larger screen sizes and higher native resolutions are possible. As substrates get thinner, the displays will in turn get thinner. There are a variety of other uses for OLED technology. In fact, Sony has developed a new application for OLED technology called Organic Thin Film Transistor (TFT). The newly developed Organic TFT can be deposited on a flexible plastic display, which is the world’s first full-color display that can project full color moving images even when the display is bent.

Sony has invested $80 million in developing this new technology & are taking it very seriously as the future of flat-panel technology. They believe it will overcome LCD & Plasma flat-panels as well. It is 3mm thick & boast a 1,000,000:1 contrast ratio. It is believed the contrast ratio is even higher than that, but there are no existing devices able to measure over that number. A 27” OLED panel was shown at the 2008 CES show in Las Vegas. Sony does not anticipate Additional sizes until at least 2010. A full roll-out of product is expected to appear in 2011.

LED TV Technology To Mature In 2011

Now we are beginning to see some interesting break-through applications and capabilities of OLED technology. OLEDs (organic light emitting diodes) have been actively developed for products and applications since about 2004, with Samsung leading the way and currently holding more than 600 US and 2800 international patents. While LG and Sony are becoming innovative leaders in utilizing OLED technologies into applications and products, Samsung produces more than 40% of the global supply of OLEDs as well as over 97% of the global production of AMOLEDs (active matrix OLEDs).
Until 2010, OLEDs had been used mostly in applications such as small, portable displays on PDAs, mobile phones, informational displays and watches. Although AMOLEDs are more expensive and much more difficult to create than PMOLEDs (passive matrix OLEDs), they can be used for larger displays (some prototypes are nearly 40?) and are very power efficient. PMOLEDs are generally better suited for hand-held displays. A 19” Samsung OLED TV industrial prototype was recently shown in November 2010 that was produced using new inkjet technology. In the most interesting recent OLED TV news, a 31” LG OLED TV was debuted, it was only 0.29mm thin (the “thinnest in the world”) and is set to become available to consumers in 2011.
OLED TV technology is different because an OLED display does not require a backlight or filtering system; it enables deep black levels while being lighter and thinner than common LCD and LED displays. In particular, OLED screens also can have a higher contrast ratio than LCD or LED screens; this makes them ideal in low ambient-light conditions such as dark rooms and theaters.
With their high efficiency, OLEDs also seem to be especially well suited for making lighting systems or individual light “bulbs” that are especially thin and lightweight.  These characteristics open the pathway for unique designs in lighting for homes, businesses and industry. Different manufacturing processes used to make OLEDs yield several advantages over flat-panel displays made with LCD and LED technologies. Potential new OLED applications such as roll-up flexible displays and screens embedded in fabrics or clothing are becoming not just possible, but probable in the next few years.
In summary, OLEDs have come a long way in the last few years. They are already making their way into every day life in PDA and cell phone displays. We can expect 2011 to be a great year for innovation in OLED applications for consumers, with early adopters being able to enjoy the first commercially produced OLED TV models on the market to be in the $2000 to $3000 range.
OLED TV Advantages and Disadvantages
OLED TV stands for organic light emitting diode television. From the word organic, it can be deduced that an OLED is using an organic based material like plastic. OLED television technology is an improved version of LED (light emitting diode). LED technology is a semi conductor that emits lights when an electric current passes through it and it is made of crystalline materials – glass. OLED display technology is the next generation screen technology. There are numerous portable devices that have an OLED technology incorporated in it and are very highly regarded. OLED technology has its advantages and disadvantages compared to other television technologies. Here are some of pros and cons of OLED television compared to other television:
OLED Advantages
•  OLED technology does not require backlighting system to create sharper, better images compared to LCD television which need a backlighting system that in comparison hinder the quality of colors that can be displayed.
•  The OLED TV technology is environmentally friendly compared to other televisions like plasmas and LCDs.
•  It is more energy efficient, especially so for portable devices that use OLED technology, therefore the life span of the battery is improved.
•  LCD television screens cannot produce deep black colors. Unlike OLED television screens which can give pure dark black colors as a result the images look brighter, sharper, and alive.
•  When watching an LCD television you must be in the right position or else the picture that you are viewing will get blurred since it cannot be viewed from wide angles, whereas OLED displays can offer wide viewing angles. They can give almost a 170 degrees viewing angle.
•  OLED television uses plastic materials hence they are lighter, thinner and flexible when compared to LCD screens.
OLED Disadvantages
•  OLED TV has a shorter lifespan compared to other television of its kind.
•  People with eye problems will have some difficulty watching OLED television.
•  OLED screens can be difficult to view in bright light.

Exactly what are these new technologies?
OLED TVs and Laser TVs offer two versions of television technology. These two types of televisions have multiple similarities to consider. They also have individual benefits to consider before you make your final purchase.
First, there are concerns over both technologies and they are:
•  Laser: Some techies have raised questions of the effect of prolonged exposure to the lasers that project the image onto the screen. Manufactures say it is fine, but research is in progress.
•  OLED: The organic material will deteriorate and this affects the picture quality. We would like to add that this is after thousands of hours use. They are looking into prolonging its lifetime.
We are sure they will be improve and addressed over time, giving us all confidence in future developments.

OLED TV
The Technology Behind OLED
OLED television (Organic Light Emitting Diode television) features LEDs that have a luminescent layer that is made of organic compounds. This technology allows a matrix of pixels to be created. This matrix of pixels allows the LEDs to emit light of multiple different colors and intensity.
Benefits of OLEDs
OLED televisions allow for a wide range of colors. The matrix that is created, along with the organic compound, allows for amazing brightness and contrast. The OLED television allow for a deeper black on the screen, which offers greater contrast with each screen. OLED TVs are also known for their low power consumption. They do not use as much power as many of the TV types on the market today, including Laser TV.
Laser TV
The Technology Behind Laser Televisions
Laser TVs use multiple waves to create the colors that are needed for the television picture. The use of lasers allows for an accurate projection.
The waves follow the idea of the old projection TVs. Laser TVs are large, utilizing the laser technology to give a clear, sharp, stable picture over a large area with great color depth, contrast and strong blacks.

Benefits of Laser TVs
Laser TVs are known for having a wider range of colors than OLED TVs. These televisions are also known for being lightweight, and for being relatively thin. Laser TVs are known for having a long life, and for keeping the picture quality throughout their lives.
Choosing Between the Two
OLED TVs are perfect for people who want a smaller TV. The current technology only allows for smaller TVs at present. If you are looking for a larger TV, you will want to look towards Laser TVs. OLED TVs rarely tip the 11 inch for commercial production. Laser TVs, on the other hand, have been created, commercially, over 60 inches.
Laser TVs have come to the market at a lower price than OLED TVs. Eventually, the price of the OLED TV will drop. The technology is still new, and is still expensive. As technology progresses and the sizes get larger, prices will lower.
Laser TVs have progressed further than OLED TVs. Eventually, the technology behind the OLED TV will catch up. Until then, Laser TVs meet the needs of the consumer more than the OLED TV. Each TV serves a different market, as the projection technology behind the laser TV caters to a larger screen.
