Plasma is injecting new life into the way that we watch TV. The term “plasma” was once restricted to a description of blood cells and ionized gases. Today, “plasma” is the stuff that seems to give modern television a life of its own.
Since televisions were first marketed about fifty years ago, the industry has evolved at a mind bending rate. From tiny rabbit-eared sets to wall-sized flat screens, televisions have grown in size and in quality. The media has grown as well. North American viewers used to have three major networks to choose from. With modern satellite programming, hundreds of programs are available with the click of a remote control.
Buying a television is no longer as simply as making a trip to the local department store. There are many points to consider when choosing a new set. Analog, or digital? HDTV ready, or HDTV enabled? LCD or plasma screen? The decision can be overwhelming, so it helps to understand a few basic points about modern day televisions.
Analog Signals
Most of us have grown up watching an analog television. This is the “old fashioned” technology that used television signals sent and received in analog format. Analog televisions are relatively inexpensive and offer good quality for minimum investment. The disadvantage of this format is that analog TV signals are only able to accommodate a limited amount of data for the screen and sound. Another drawback is that analog signals can be easily and immediately corrupted by outside forces. If you have an analog television, those no need to worry. Analog service will be available and your set will work just fine even after other formats begin to dominate the market.
Digital
Digital television signals allow stations to send dense data that has more definition, with less degradation of the signal. Therefore, viewers are able to enjoy an increased level of quality in both the picture and the sound. This enhanced quality is particularly clear while watching DVDs.
HDTV (High Definition Television)
High definition is quickly passing traditional digital as the new standard in television viewing. Customers are able to enjoy the highest levels of audio and video quality when television stations transmit signals in high definition television (HDTV) format. To enjoy this format, your television set must be able to receive and process the specialized signals, and display them on an HDTV-enabled screen. All of the elements combined will create a stunning visual and audio experience.
Digital television and HDTV are commonplace in today’s communications industry, but viewers cannot appreciate the pristine levels of sound and picture if they use old, outdated television sets. Thanks to recent advancements including HDTV, DVD-Video, DTV, digital satellite broadcasts and computer video, our generation truly is in the midst of a digital video revolution. Plasma display technology is one more giant leap forward in modern television technology.
Plasma screens entered the US market toward the end of 1999, but the concept was initially put into place at the University of Illinois in July 1964. These first displays were nothing more than points of light formed in laboratory experiments. From this starting point the technology began to improve, and by the late 1960s it had advanced to the point where scientists were able to put up geometric shapes. Today, thanks to the development in high speed digital processing, materials and advanced manufacturing technology, brighter full-color plasma display screens are widely available.
Plasma televisions have taken technological leaps and bounds ahead of other television technologies, making them the fastest-selling ‘new’ television technology on the market. Plasma television screens provide a higher resolution compared to conventional TVs, and many new plasma televisions are capable of displaying HDTV signals. In addition to superior picture quality, plasma televisions can be wall mounted, saving valuable floor space and offering a theater-like display.
With HDTV displayed on a plasma screen, it’s like you’re seeing your favorite movies and television programs for the very first time.
