Where Did LCD Tvs Originate?

There are three technologies today that are competing to be the number one TV technology: LCD, Plasma, and DLP. LCD will likely be the winning technology.

LCD TV’s popularity has recently exploded. The technology is expanding and is now comparable to that of IBM and DVD. LCD TVs are the most up-to-date high-definition televisions with rich picture and color quality. It is a little known fact that LCD technology actually dates back to the year 1888 when the properties of liquid crystallization were discovered by Austrian scientist Friedrich Reinitzer. That would make the concept of LCD TV at least eighty years old! Probably the first efforts to utilize the process of liquid crystallization for commercial products were taken by George Heilmeier, an Electrical engineer from the University of Pennsylvania. Heilmeier also held Ph.D, M.S.E, & M.A’s in Solid State electronics from Princeton University. He went on to work with RCA and while working along side Lucian Barton, Joseph Catellano, Joel Goldmacher, Nunzio Luce, Louis Zanoni and Richard Williams he shaped LCD technology, one piece at a time.

Before LCD TV came together as a whole, individual parts of the technology were first developed. Liquid crystal display (LCD) was the result of experimentation with liquid crystals. While dabbling in this technology RCA found that it was possible to create digital clocks, watches, calculators, and so on. The digital alarm that is common to timepieces today is due to Heilmeier’s work with RCA.

James Fergason, a graduate from the University of Missouri was passed the baton of LCD technology and developed it further. As the Liquid Crystal Institute associate director at Kent State University, Fergason discovered the nematic field effect, which took the prototype LCD TV displays of Heilmeier’s team toward the present-day LCD technology.

Fergason’s team unveiled the first LCD TV in 1971, which unfortunately proved to be a disappointment in terms of the “phantom images” that were visible during action broadcasts. After making adjustments and the addition of reverse pull-down correction, the picture quality on modern-day LCD TV is excellent, hardly ever allowing distorted picture transmission. As a result of his work fine-tuning LCD technology, Fergason began his own corporation and forged over 100 patents.

LCD TV today is an amazing experience. At this rate, LCD TVs are sure to replace the old CRTs as the television-watching technology of the future. LCD TVs now are High Definition capable and provide an astonishing viewing resolution. It is also a favorite for individuals with home theaters.

Best answer:

Answer by J. Charles
It took me 2 months of research!
I opted for LCD over Plasma,and I am Not disappointed!
Points to Consider:
1)Size of Room (TV ratio = Screen size x3 for Optimal Viewing distance).
2)Wall Mounted Versus On top of Audio Video Stand.
3) Is it a Main Viewing area, or are you considering placing them around the Home(Bedroom,Kitchen Etc).
4) Will you be Viewing HD Cable Transmissions as well as Blue ray and HD DVD Source.

I went with Panasonic Viera Range of LCD’s,(32 Inch Main, and Several 26 Inch Models for round the Home)
All Interlinked through a Media Center with HDMI Cabling , to AV Cinema Speakers and processor.

This Model comes with 2 HDMI inputs,Composite Audio IN and the Technology and Picture Quality is the Best!(I’m sure you could spend More,but Panasonic is Reliable!!)
I Love my Set up,but having good Cabling and Great Sound is very Important to compliment the High Quality Images you will See!
Hope this Helps!

Question by Jason A: Is regular standard-def content WORSE on an LCD compared to a tube television?
I have heard a lot about how Standard-Def content (e.g. regular television shows) doesn’t look great on HD LCD TVs, but I am wondering if Standard-Def stuff actually looks WORSE on an HD LCD TV compared to a regular Standard-Def tube TV.

Thanks for any info.

In some cases yes (even assuming you watch the same size and from the same distance). It’s a matter of the scaler in the TV … which is often crappy … and the artifacts produced when the SD signal is scaled to fit the native LCD screen resolution. Demo the TV before deciding if you plan to watch much SDTV, and remember to sit further back (as you would for a CRT SDTV).
