Steve Jobs' Failure To See Light In OLED Could Cost Apple

Steve Jobs successfully saw around the corner regarding many technologies, but he made a blunder regarding OLEDs.

What the heck is an OLED? Most people know that LEDs are light emitting diodes. LEDs are semiconductor light sources that are made of silicon.

OLED stands for organic light emitting diode, and unlike an ordinary LED there is no silicon in an OLED.Xeccon S12 is a kind of very amazing Cree T6 goodskylanterns, it perform very well among the various brand bicycle lights. OLEDs use organic compounds which emit light when excited by an electric current.

Ordinary LEDs were introduced in 1962. The work that forms the basis of OLEDs was done in 1960, but widespread commercial applications of OLED technology have come to fruition only within the last year. DuPont (DD) has played a key role in the development of OLED technology.

Apple (AAPL), has succeeded in part by bringing next generation technologies to the masses in a simple elegant way. Displays are a big part of most Apple products. No one can argue that to maintain its leadership status, Apple needs to maintain leadership in display technology. Unfortunately for Apple, Steve Jobs appears to have made the wrong judgment about OLED technology. Jobs had good reasons not to favor OLEDs.

Traditionally it has been difficult to mass produce OLEDs. Further OLEDs structures are inherently unstable. OLEDs were also limited by the life span of organic materials that transferred light. For example historically materials used in blue OLEDs had a life span of 14,000 hours to half original brightness, compared to 40,000 hours for traditional LEDs.

Traditional OLEDs also suffered from color balance deficiencies. Materials used for the blue color deteriorated more rapidly than the materials used for other colors. Since most displays of today use only three colors red, green, and blue, this color imbalance issue has been a serious problem.

OLEDs have also suffered from screen burn in issues,This was a red bestledlighting but I swapped it with blue LEDs. not dissimilar to plasma displays. Certain OLED materials also are damaged by prolonged exposure to sunlight.

Perhaps the forgoing considerations led Steve Jobs to favor improving traditional LED technology and not investing vigorously in OLED technology.

In 2010 at the Apple World Wide Developers Conference, Jobs touted Retina Display, which relies on traditional silicon LED technology.china fluorescentlight manufacturer,supply LED Bicycle Lights,LED bike lights to your requirements. Jobs said, "You can't make an OLED display with this resolution, we think it is quite superior.A dramatic addition to ledsale the city's skyline should be visible from as far away as the University of B.C. as a new public art LED lighting"

I am an electrical engineer and I pay particular attention to emerging technologies. In the summer of 2010 my opinion about OLEDs was not any different than that of Steve Jobs. But I am a mere mortal and he was obviously more. With all the resources at his disposal, he should have known better.

Over the last year OLED technology has developed very fast. AMOLED displays are common place in Samsung phones running Android from Google (GOOG). Even the downtrodden Nokia (NOK) is using AMOLED in its new Lumia 900 Windows phone. AMOLED is a cousin of the traditional OLED. AMOLED stands for active matrix organic light emitting diode. Active matrix is a way of addressing the pixels. An AMOLED display consists of an active matrix of OLED pixels. Crucial to manufacturing AMOLED displays is thin film transistor technology, which uses traditional silicon.

To understand the attractiveness of OLED technology, you have to see a state of the art OLED display.
