Who invented plasma TV?

The invention and appearance of television is not the result of one person's efforts, but the result of long-term research by many people and scientists. The first generation TV sets were not completely electronically controlled, but used rotating discs driven by small motors and NeonLamp to play images. At that time, the picture was only half the size of a card, and the color was not black and white, but dark orange red. The image is dim and fuzzy, and only some people and wheels can be seen with the naked eye, but this kind of performance was very exciting at that time. 1925 John? 6? 1 Logie? 6? 1 Baird developed the TV with the collected old radio equipment, neon tubes, scanning disks, electric heating rods, magnetic tired lamps and photocells that can generate electricity intermittently. On April 30th, 1939, the world's first TV set was unveiled at the new york World Expo. That year, the United States only played two hours a week. Since the invention of television for decades, television has always relied on traditional display technology. These decades of technology have turned the original black-and-white TV into color; The original rounded figure has evolved into a flat square ruler. In terms of volume, the greater the number of feet, the heavier it will become. Although the screen has a lot of feet, the quality of the screen is always unacceptable due to the technical problems of the display screen, so the commonly used size is only about 34 inches. In fact, the birth of plasma as early as the 1960s, American scientists realized this problem, so they concentrated on how to make a big TV with good books and picture quality, and the name plasma began to appear in scientists' minds. 1989, Fujitsu of Japan took the lead in launching the world's first mass-produced 20-inch plasma display screen. The plasma display screen introduced in the early stage is only used for commercial purposes, and it is mostly used in conference rooms, shops and some large-scale exhibitions to play propaganda statements, advertisements, train and flight information, financial information, real-time camera shots, maps and condensed atmosphere. The world's first home plasma display technology was invented in the United States, and this technology suddenly stopped. In the early 1990s, Fujitsu of Japan redeveloped this technology and quickly introduced the first 20-inch color plasma TV. Until1996165438+10, Fujitsu finally introduced the first 42-inch home plasma display screen, which made the plasma display screen not only used for business, but also enjoyed high-quality TV effects at home. However, the plasma introduced at that time can only be called display screen, because it is only a computer display screen, which is used to play DVD, video recorder, VCD player and other interfaces, and there is no TV receiver, so you can't see TV programs. So far, there are some plasma display built-in tv frequency modulators, but there are also many plasmas without TV receivers. At present, the technology of developing plasma display panels is dominated by Japan, and the world's four major panel manufacturers FHP, NEC, Panasonic and Pioneer are all developed by Japanese. Until the end of 1990s, South Korea's plasma technology began to emerge, LG and Samsung became two major panel manufacturers outside Japan, and small-scale plasma manufacturers appeared around the world to develop different plasma technologies. The plasma world of 2 1 century has entered 2 1 century, and plasma display screen is not only a commercial product, but also has the trend of replacing CRT TV. At present, plasma display panels can be said to have reached a stage close to maturity. In fact, not long ago, some manufacturers denied plasma, including Sony and Sharp. Needless to say, Sony is the first Japanese industry to develop plasma technology. As early as the late 1970s, Sony appointed Mr Masaru Ibuka to take charge of development and research, but due to the complexity and difficulty of technology, the research was finally terminated. Subsequently, Fujitsu, Panasonic, Pioneer, Hitachi and NEC entered the plasma display panel market one after another, and they all made great efforts to develop a new generation of plasma display panels, and also achieved good results. In 2006 54 38+0-2002, the market share of plasma display panels increased significantly, and it is believed that plasma display panels will block the CRT TV market in the near future. The growth course of plasma: 1925, John Logie Baird will develop TV 1939, the world's first TV will come out 1964, Philips will release monochrome DC display 1972, Japan will start to study plasma display 1989, and Fujitsu will launch the world's first. A mass-produced 20-inch plasma screen 1996 Fujitsu launched the world's first home 42-inch plasma screen 1999 Pioneer released the features of deep waffle rib panel 1999 FHP released ALIS panel Panasonic completed the contrast ratio of 3000: 1.
