After the creation of electricity and radio, television was invented afterwards. The inventors who produced the televisions we are using now, have brought a life-shaping, magnetic influence to the masses and in the public. To watch in a more distant way is like an emphatically meaning to the word “television”. Cable sites attempt to magnetize audiences with precise tastes, while public and commercial television sites address the public or the mass. Through close-circuit television, problems about security and surveillance in hospitals, schools, and businesses property are being handled properly.
Because the invention of television involved complex procedures, no one can determine who really the founder is or who that specific scientist that brought it to reality. There have been also a number of great scientist who were responsible to its improvements thus, we can hardly identify to whom the credit should be given. Early as the 1800’s, it was known and understood that the radio communication’ signal could be transferred through air. Later that year, after people have known about how radio waves are being transferred, television was brought to life. Some of us are already aware and well-informed regarding the founders and the people who are involved in experimentation of the electromagnetism theory whom were Michael Faraday and Joseph Henry. We also know that they are responsible for the establishment of setting up electrical communication. And then, in 1844, the telegraph that was first invented by Samuel Morse and followed by the scientist that sent the first sets of image over the distance by means of a “pantelegraph” who is Abbe Giovanni Caselli, an Italian. In addition, two more Englishmen, which were May and Smith, have used selenium and light along with the idea to change images into electrical signals. Then, eventually, an inventor named Paul Nipkow has acquired the first mechanical television scanner in Germany.
Many of these great men are responsible of how the Television was first invented and augmented. Each experiment they have undertaken and has successfully accomplished was a marvelous contribution in the development and breakthrough of televisions. As many decades have passed by, much advancement in the making of the television took place. Such various types of television which have emerged are flat screen TVs, Plasma TV, LCD TVs and high definition TVs. All of these televisions have their own unique characteristics and performance.
Plasma TVs induce pictures from a gas (plasma) distend with xenon and neon atoms as well as millions of electrically charged atoms called electrons. These particles eventually collide and hit one another when you turn on the power of your television. The energy produced from their collisions generates and causes the increase in the energy level of the plasma. On the other hand, the neon and xenon further release photons of light (similar to the way neon lights work). Plasma TVs offer large viewing areas (up to 50 inches) but are very thin. While they offer excellent picture quality, they are, withal, quite expensive and are fast becoming the popular choice for HDTV.
Another type of television was invented adjacent to the creation of plasma TVs. Liquid-crystal display televisions (also known as LCD TV) are television sets that utilize LCD display technology in order to produce images. LCD televisions are thinner and lighter compared to Cathode ray tube (CRTs) of similar display size, and are available in much larger sizes. Despite of its considerably high price, consumers still prefer to acquire it over the conventional CRT TV because of its features and advanced specifications. In the event when manufacturing costs fell, this combination of features from LCD television made it more convenient for people who are yet planning to buy a TV set.
The High-Definition televisions, unlike LCD television, provide a resolution that is substantially higher than that of standard-definition television sets which were previously mentioned above. Chiefly when transmitted at two megapixels per frame, HDTV provides about five times as many pixels as SD (standard-definition television).
Flat screen TV
Furthermore, flat panel displays (usually called Flat screen) which is also one of the latest types of TV sets being made available in the market today, encompass a growing number of technologies enabling video displays that are much lighter and thinner than traditional television. It also implements video displays that use cathode ray tubes, and are usually less than 100 mm (4 inches) thick.
