The development of consumer electronics, high-definition displays, digital broadcasting, displays and media is growing at an increasing rate. Technological advances are faster than ever, reducing the time it takes to introduce new technologies to the market at an exponential rate. With each major breakthrough, the algorithm for designing and delivering new technologies is nearly 50% shorter. With this rapid competition for inventions, the introduction of various technologies is inevitable for price erosion and shortened life cycles that are considered "new" in consumer electronics.
The brief history of television and the development of display devices have highlighted the phenomenal growth rate of development technology.
In 1876, Eugene Goldstein coined the term "cathode ray" to describe the light that was emitted when a current was forced through a vacuum tube. Fifty years later, in 1928, General Electric introduced an octagonal TV set, a television set with rotating discs and neon lights, which created a red-orange picture that was half the size of a business card. In 1948, twenty years later, the demand for black and white television began to change in communication and entertainment. By 1949, several familiar brand names had reached a booming market share. These brands include familiar names such as Admiral, Emerson, Motorola, Philco, Raytheon, RCA and Zenith. The market also plans to work with brands such as Crosley, Du Mont, Farnsworth, Hallicrafters, Sparton and Tele-Tone. In 1951, CBS broadcasted an hour of Ed Sullivan color television programs, but only more than 20 CBS televisions were able to handle color broadcasts. In 1954, RCA introduced the first color TV set to the market, but only sold 1,000 units to the public that year. In 1956, Time magazine called the color TV "the most resounding industrial user in 1956."
The Plasma Display Group was invented in 1964 by Donald H Bliter, H Gene Slottow and student Robert Wilson at the University of Illinois. Original monochrome displays were popular in the early 1970s because they did not require memory or circuitry to refresh the image. By 1983, IBM introduced a 19-inch monochrome display that could display four virtual sessions simultaneously. By 1997, Pioneer began selling the first color plasma TV to the public. The screen size increased to 22 inches in 1992. In 2006, Panasonic introduced the 103-inch largest plasma video display at the Consumer Electronics Show [CES] in Las Vegas, Nevada.
DLP was developed by Dr. Larry Hornbeck at Texas Instruments in 1987. An image is created by selectively reflecting a colored light beam on a digital micromirror device [DMD chip]. Each mirror represents one pixel on the projected image. The number of pixels represents the resolution. For example, a 1920 x 1080 resolution refers to a single spot grid of 1920 x width x 1080 height, produced by a beam of light reflected from the same number of tiny mirrors that are smaller than the stamp. Concentrated light from a bright mercury arc lamp is transmitted through a red, green, blue and sometimes white small rotating color wheel. Light passing through the color wheel is reflected on the small mirror and acts independently to direct the colored light at or away from the pixel target. The color perceived by the human eye is a mixture of combinations of red, green, and blue reflections in each pixel, and the combination of pixels creates a total image. This technology is widely used in digital projectors and is becoming a competitive technology for cathode ray tube projection televisions, at least until consumers find the cost of replacing high-intensity projection lamps.
In 1904, Otto Lehman published an article about liquid crystals. By 1911, Charles Mauguin described the structure and properties of liquid crystals. In 1926, Marconi Radio reported the first practical application of the technology. It was not until 1968 that a team of George Heilmeier and RCA introduced the first operational LCD display. In December 1970, M. Schadt and W. Helfrich of the Central Research Laboratory at Hoffman-LaRoche in Switzerland applied for a patent for twisted nematic field effects in liquid crystals and licensed the invention to the Japanese electronics industry for digital quartz watches. By 2004, 40-inch to 45-inch LCD TVs were widely available on the market, and Sharp introduced a 65-inch display. By March 2005, Samsung introduced an 82-inch LCD panel. Then in August 2006, LG Philips introduced a 100-inch LCD monitor. At the Consumer Electronics Show [CES] in Las Vegas, Nevada, in January 2007, Sharp once again claimed to be the number one in size because they launched a 108-inch LCD panel called AQUOS. From tiny liquid crystals to scrambling for hegemony and 108-inch displays, the need for larger sizes and sharper contrast in high-definition video has once again proved that size is critical.
By 2006, there were more than 220 TV manufacturers, and this list is growing as the type of display technology continues to expand. Other display technologies include vacuum fluorescent displays [VFDs], light-emitting diodes [LEDs], and field emission displays [FEDs] that are not to be confused with K-FED and liquid-based liquid crystal [SED]. As the ability to generate and deliver high-definition broadcasts on demand continues to grow, the need for improved quality and larger displays will continue to increase proportionally. The next major leap forward in observing high definition and high quality image reproduction will be the Surface Conduction Electron Emitter Display [SED].
So where will high-definition images come from? The pace of this technology and the competition for formats are faster than the development of display devices.
Ampex launched its first commercial video cassette recorder in 1956 for $50,000. The world's first home video tape recorder was launched by Philips in 1972. By 1975, Sony introduced Betamax. The first VHS recorder was launched in 1977, and JVC's HR-3300 created a format war that raged in the market share in 19880. By the 1990s, the dominance battle between VHS and Beta was replaced by a new war between SONY and Philips' MultiMedia discs and ultra-density discs supported by Time Warner, Panasonic, Hitachi, Mitsubishi, Pioneer, and Toshiba. And Thomson. Surprisingly, IBM's president, Lou Gerstner, came forward and became a matchmaker to persuade competitors to combine and combine the best of the two technologies into one standard. The result became the DVD Alliance, which was later called the DVD Forum. Competing technology collaborates with standards for the manufacture of DVD products with a common format until 2006, when the battle between HD DVD and Blu-ray HD video competes for supremacy.
It took 20 years to migrate from a $50,000 commercial device to a home video tape recorder. In the format war between VHS and Beta, this was a battle for nearly 20 years, until the competition camp under the guidance of Lou Gerstner developed a common DVD format. The normal DVD format lasted only a decade, until competing technology once again dominated the HD video market, as HD DVD and Blu-ray compete for hegemony, film titles, profits and bragging rights to define the next standard for video evolution. In the pace of this technological development, progress occurs at twice or half the speed of the advancing era. At this rate, we can foresee the next major improvement in technology and other formats over the next five years. Does the next format combine the best technology for HD DVD and Blu-ray? The next step in evolution is based on using more colors in the spectrum to create higher definitions? Will the format war of storage media such as VHS tapes and Blu-ray discs become obsolete as new media is converted to on-demand wireless video streaming? One thing is for sure, it doesn't take long to find the answer. Stick to your VHS movies, CDs and DVDs, as these will be collectors' items and museum works, and then today's children will graduate from college.
When are you buying consumer electronics next time, are you worried about having the latest technology? Are you worried about choosing the right format, so your movie library and media collection will last longer than your LP record and eight tapes? Choose a monitor that supports digital HD, learn about the INPUTS type of your display device or TV, and choose the monitor that fits your budget. The type of INPUT and connection is important for being able to take advantage of the best display of a television or display device. For recorded media, you can choose the media with the most titles and be compatible with your other entertainment devices. The most advanced technology you buy today is likely to be out of date before your extended warranty expires, so sit back and enjoy this development.
