The Rapid Pace of Evolution in Consumer Electronics

The evolution of consumer electronics, high definition displays, digital broadcasts, displays and media is happening at an increasingly rapid pace. Technological advancements are happening much faster than ever before, reducing the time to market for new technologies at an exponential rate. The algorithm for designing and delivering new technologies is a time reduction of almost 50% with each significant breakthrough. With such a rapid race for invention, the simultaneous introduction of various technologies is as inevitable as the erosion of prices and shortened lifecycles for what is considered “new” in consumer electronics.

A brief history of television and the advancement of display devices highlights the incredibly increasing rate of development of technology.

In 1876, Eugene Goldstein coined the term “cathode ray” to describe the light emitted when an electric current is forced through a vacuum tube. Fifty years later, in 1928, GE introduced the Octagon, a television with a spinning disc and a neon light that created a reddish orange image that was half the size of a business card. In 1948, twenty years later, the demand for black and white television began a transformation in communications and entertainment. In 1949, several well-known brands fought for a share of the booming market. These brands included household names like Admiral, Emerson, Motorola, Philco, Raytheon, RCA, and Zenith. The market was also saturated with brands like Crosley, Du Mont, Farnsworth, Hallicrafters, Sparton and Tele-Tone. In 1951, CBS broadcast an hour-long Ed Sullivan color show, but there were only two dozen CBS televisions capable of handling the color show. In 1954, RCA introduced the first color television to the market, but only 1,000 units were sold to the public that year. In 1956, Time Magazine called color television “the most resounding industrial flop of 1956”.

The plasma display panel was invented at the University of Illinois in 1964 by Donald H Bliter, H Gene Slottow, and student Robert Wilson. The original monochrome displays were popular in the early 1970s because they did not require memory or circuitry to refresh images. In 1983, IBM introduced a 19-inch monochrome display capable of simultaneously displaying four virtual sessions. In 1997, Pioneer began selling the first color plasma televisions to the public. The screens grew to 22 inches in 1992, and in 2006, Matsushita unveiled the world’s largest 103-inch plasma video display at the Consumer Electronics Show (CES) in Las Vegas, Nevada.

DLP was developed at Texas Instruments in 1987 by Dr. Larry Hornbeck. The image is created by selective reflection of colored light beams on a digital micromirror (DMD chip). Each mirror represents one pixel on the projected image. The number of pixels represents the resolution. For example, the resolution of 1920 x 1080 refers to a grid of individual points of light 1920 x 1080 high, created from the beam of light reflected from the same number of tiny on-chip mirrors that is smaller than ‘a postage stamp. The concentrated light from a bright mercury arc lamp is diffused through a small rotating color wheel of red, green, blue and sometimes white. Light passing through the color wheel is reflected off the tiny mirrors which act independently to direct the colored light towards or away from the pixel target. The colors perceived by the human eye are a mixture of combinations of the red, green and blue highlights in each pixel, and the combination of pixels creates the total image. This technology has been widely used in digital projectors and has gradually become a competitor technology for CRT projection televisions, at least until consumers find out the cost of replacing high intensity projector lamps.

In 1904, Otto Lehman published a work on liquid crystals. In 1911, Charles Mauguin described the structures and properties of liquid crystals. In 1926, the Marconi Wireless Telegraph Company patented the first practical application of the technology. It wasn’t until 1968 that George Heilmeier and a group from RCA presented the first working LCD screen. In December 1970, M. Schadt and W. Helfrich of the Hoffman-LaRoche Central Research Laboratories in Switzerland filed a patent for the twisted nematic field effect in liquid crystals and licensed the Japanese electronics industry for watches. – digital quartz bracelets. In 2004. 40 inch to 45 inch LCD TVs became widely available in the market, and Sharp introduced a 65 inch screen. In March 2005, Samsung introduced an 82 inch LCD panel. Then in August 2006, LG Philips unveiled a 100 inch LCD screen. At the Consumer Electronics Show (CES) in Las Vegas, Nevada in January 2007, Sharp once again claimed the top spot for size by showcasing the 108-inch LCD panel under the brand name AQUOS. From tiny liquid crystals to the battle for supremacy and 108-inch screens, the demand for larger size and sharper contrast in high-definition video has proven once again that size matters.

In 2006, there were over 220 TV manufacturers, and the list grows as the types of technology for displays expand. Other display technologies include Vacuum Fluorescent Display (VFD), Light Emitting Diode (LED), Field Emission Display (FED), not to be confused with K-FED, and liquid crystal on silicon (SED). As the ability to generate and deliver on-demand high definition programming continues to grow, the demand for improved quality and larger screens will continue to increase proportionately. The technology to watch for the next big leap in high definition and quality image reproduction will be the Surface Conduction Electronic Emitter (SED) display.

So where will high definition images come from? This pace of technology and format battle is even faster than the development of display devices.

Ampex launched the first commercial video recorder in 1956, with a price tag of US $ 50,000. The world’s first VCR for home use was launched by Philips in 1972. In 1975, SONY launched Betamax. The first VHS VCR hit the market in 1977, JVC’s HR-3300, creating a format war that raged for market share during the 19080s. In the 1990s, the battle for dominance between VHS and Beta has been replaced by a new battle between the MultiMedia Compact Disc from SONY and Philips, against the Super Density Disc backed by Time Warner, Matsushita, Hitachi, Mitsubishi, Pioneer, Toshiba and Thomson. Surprisingly, it was Lou Gerstner, president of IBM, who stepped forward and acted as a go-between to convince rival camps to collaborate and combine the best of both technologies into one standard. The result of what became the DVD Consortium, later became known as the DVD Forum. Competing technologies collaborated on manufacturing standards for DVD products with a common format until the battle for supremacy was revived in 2006 between HD DVD and high definition video Blu-Ray.

It took 20 years to go from a commercial $ 50,000 device to a home VCR. It was almost 20 years of battle in the format war between VHS and Beta, until rival camps under the direction of Lou Gerstner collaborated on a common DVD format. The common DVD format lasted barely a decade until competing technologies once again took the battle to claim dominance in the high-definition video market, as HD DVD and Blu-Ray battled it out. for supremacy, movie titles, profit and bragging rights. to set the next standard in the evolution of video. At this rate of technological change, advancements are happening twice or twice as fast as the current era. At this rate, we can anticipate the announcement of the next significant technological breakthrough and another format in the next five years. Will the next format combine the best technologies of HD DVD and Blu-Ray? Will the next evolutionary step be based on using more colors of the spectrum to create even greater definition? Will the format war for storage media like VHS tapes and Blu-Ray discs become obsolete as new media transforms into wireless video streaming on demand? One thing is for sure, it won’t take long to find out. Hold on to your VHS movies, CDs and DVDs as they will be collectibles and museum pieces before a child born today graduates from college.

Are you concerned about the latest technology on your next consumer electronics purchase? Are you worried about choosing the right format, so that your movie library and media collection will outlast your stack of LP discs and eight-track tapes? Pick a display that supports digital high definition, learn about the types of inputs for your display device or TV, then choose the one that fits your budget. The types of INPUT and connections are important in order to get the best possible display from your TV or display device. When it comes to recorded media, try your luck on the media that have the largest selection of titles and that are compatible with your other entertainment devices. Chances are the cutting edge technology you buy today will be obsolete before your extended warranty expires, so sit back and enjoy the evolution.
