Animated Figures Shown On Screen During Dodger Game Tonight?

Large-screen television

A jumbotron,^[i] sometimes referred to as jumbovision, is a video display using large-screen television applied science (video wall). The original technology was developed in the early 1980s past Mitsubishi Electric^[2] and Sony, which coined JumboTron equally a make name in 1985.^[3] Mitsubishi Electrical sold their version of the technology every bit Diamond Vision. Information technology is typically used in sports stadiums and concert venues to show shut up shots of an outcome or even other sporting events occurring simultaneously,^{[4] [v]} likewise as outdoor public places (such as Times Square, for example).^{[half dozen]}

History and development [edit]

The jumbotron was invented in Japan during the early 1980s, merely in that location is a dispute between 2 rival Japanese companies, Mitsubishi Electrical and Sony, over its invention.^[2] In 1980, Mitsubishi introduced the kickoff large-scale video board,^[7] the Diamond Vision, which was a big screen using cathode-ray tube engineering similar to traditional tube televisions.^[ii] They demonstrated the technology at the 1980 Major League Baseball All-Star Game in Dodger Stadium, Los Angeles.^[7]

Panasonic had the Astro Vision which was based on Fluorescent Discharge Tubes. These were the only 3 players in the large-screen industry.

Ironically, it was Sony who introduced Daktronics to the pro and college sports world, as Sony would exclusively sell Daktronics scoreboards and controllers with their video board solutions. Eventually Daktronics replaced Sony in the space completely.

In 1985, the term "JumboTron" was coined by Sony for its large-scale video board.^[7] The JumboTron was the make name for the large-scale video boards originally manufactured by Sony, and is recognized as one of the largest non-projection video displays ever manufactured. Sony creative director Yasuo Kuroki, who previously helped create the Walkman, is credited with the development of the JumboTron.^[2] Information technology was introduced at the Expo '85 held in May 1985 at Tsukuba, Ibaraki. It had a display resolution of 450,000 pixels, using a new proprietary Sony technology called the Trini-lite.^[three] It was a microprocessor-based low-cal bulb adult past one of Kuroki'due south colleagues, principal Betamax engineer Yuji Watanabe. Trini-lite technology allowed screen clarity and computer control, laying the foundation for the showtime Sony Jumbotrons.^[2]

While the JumboTron and similar big-screen displays are physically large, they ranged from low to medium brandish resolutions. While the original Sony JumboTron in 1985 had a 450,000-pixel resolution, comparable to standard-definition televisions of that era,^[3] sure after models had lower resolutions. The JumboTron at the now-demolished Tampa Stadium in Tampa, Florida, measured xxx ft (nine m) diagonally, with a resolution of only 240x192 pixels, beneath VHS resolution. Screen size since so varies depending on the venue. The brandish introduced in 1985 was 40 meters wide by 25 meters tall. Newer, LED-based big screens have resolutions that are an order of magnitude greater than the early JumboTron resolution at a fraction of the price. For example, the much publicized middle-hung video board in the Dallas Cowboys' AT&T Stadium is 72 feet tall and 160 feet wide (22 1000 10 49 m), displaying HDTV at 1920 ten 1080 resolution, 45 times more pixels.

The largest JumboTron in use was located at SkyDome (at present Rogers Centre) in Toronto, Ontario, and measured 10 k tall past 33.five m wide (33 ft × 110 ft) at a toll of US$17 meg. By comparing, a similar-sized LED arrangement sold today would toll around $iii one thousand thousand. The Rogers Eye JumboTron was replaced in 2005 by a Daktronics ProStar as function of a stadium revitalization projection.

Sony JumboTron was the outset video board always in Times Square. It remained that way for about ten years.

Purpose [edit]

Originally, JumboTrons solely displayed the scores of the games via numerical displays. This then evolved into instant replays being showcased for the benefit of fans inside the stadiums or arena, and in mod day, social media is heavily integrated, with fans being urged to post on diverse social media platforms to so accept their content appear on the JumboTron screen.^[8]

Sony JumboTron's were the world'southward first mobile screens and concert screens. Big Mo was the first portable video screen and Genesis used the first portable video screens for concert tours in the mid-ninety's.^{[ citation needed ]}

Specifications of product and blueprint [edit]

Originally, the JumboTron was non an LED display (light-emitting diode display), since blue LEDs were unavailable at the time, and the only dark-green LEDs available were of the traditional yellowish-light-green variety, which were unsuitable for an RGB display. Each display consisted of multiple modules equanimous of 16 or more than small alluvion-axle CRTs (cathode ray tubes), each of which included from ii to 16 pixels equanimous of red, dark-green, and blue phosphors. Sony displayed ane of the earliest versions at the Expo '85 Globe's Fair in Tsukuba. Eventually, JumboTron systems adopted LED technology as blueish and pure green LEDs were developed. LED-based systems have most ten times the lifespan of CRT-based systems, a key reason for the alter.

Genericized trademark [edit]

Although JumboTron is a registered trademark owned past the Sony Corporation, Sony stopped manufacturing the devices under that proper name in 2001 and the word jumbotron has since go a genericized trademark.^[5]
