Revisiting History – How LCD TV-The World's Current Number One TV Technology-Came About
We all know that the world's number one TV technology today is none other than the LCD TV. The technology used by its competitors known as Plasma and DLP are all left far behind.
Today, LCD TV demands have rapidly grown worldwide. The LCD TV's expanded technology makes it the most up-to-date in high definition televisions today. It can even be compared with the technologies used by that of IBM and DVD. However, have you ever wondered how this number one TV technology came about?
The technology of LCD was discovered by an Austrian scientist named Friedrich Reinitzer. Friedrich Reinitzer discovered the properties of liquid crystallization more than 80 years ago in 1888. Later on, George Heilmeier, who was an Electrical Engineer from the University of Pennsylvania, made the first efforts of utilizing the process of liquid crystallization for commercial products. Besides being an Electric Engineer, Heilmeier also held MA, MSE, and PhD's in several fields of Solid State Electronics. All of these achievements he garnered from Princeton University. In the RCA Laboratories, he worked with Richard Williams, Lucian Barton and Louis Zanoni. He also worked with Joseph Catellano, Nunzio, Luce and Joel Goldmacher. During his work at the RCA Laboratories, he experimented one by one with different molds and worked with the different liquid crystallization methods. The work he performed at the RCA eventually became stepping stones in shaping the LCD TV technology as it is being used today.
But before the method of Liquid Crystal Display (LCD) was applied to be used on televisions, there have been several stages of experimentation with the LCD technology.
In the RCA laboratories during the time of George Heilmeier, there were a lot of experiments done using liquid crystals. As a result of these several experiments, George Heilmeier and his team found out that this technology, the LCD, can be crafted to be used for digital gadgets. Such digital gadgets include digital clocks, digital watches, digital calculators and many more. Its potentials were limitless. The digital alarm that we commonly use in our watches today is attributed to the work done by George Heilmeier at the RCA.
The next in line to be expanding the LCD technology was James Fergason. He was a graduate of the University of Missouri. He was the associate director of the Liquid Crystal Institute in Kent State University. While being an associate director there, he discovered something called the nematic field effect. This discovery subsequently took the technology of the LCD that he had inherited from Heilmeier's team toward the modern LCD technology that we currently use today.
However, Fergason's discovery of present day LCD technology was not perfected squarely at that instant. When his team debut their first LCD TV in the year 1971, it was a disaster. Everyone was disappointed. The images reflected in his team's television were filled with "phantom images" during the TV's action broadcasting.
They had to make a lot of adjustments. After adding a method called "reverse pull-down correction" their LCD TV became a hit. The picture quality was excellent and there were hardly any picture distortion during transmission of images. Because of this success, Fergason started his own corporation. With his corporation he then forged over 100 patents worldwide.
Today, viewers of television using LCD TV's report having a one of a kind viewing experience. At the rate of the LCD TV's popularity, LCD TV's are to replace the old CRTs as the technology to be used in the future of television manufacturing. Especially now that LCD TVs has amazing capabilities of providing high viewing resolutions which, when connected to all other electronic gadgets, deliver a home theater experience.
