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.
