Jumbotron
A jumbotron, sometimes referred to as jumbovision or a jumbo screen, is a video display using large-screen television technology (video wall).
The original technology was developed in the early 1980s by Mitsubishi Electric (using the name Diamond Vision) and Sony, which registered JumboTron as a trademark in 1985. It is typically used in sports stadiums and concert venues to show team statistics, close-up shots of an event or even other sporting events occurring simultaneously. The same jumbotron technology is used in outdoor public places, often for advertising purposes (such as Times Square, for example).
The jumbotron was invented in Japan during the early 1980s, but there is a dispute between two rival Japanese companies, Mitsubishi Electric and Sony, over its invention. In 1980, Mitsubishi introduced the first large-scale video board, the Diamond Vision, which was a large screen using cathode-ray tube technology similar to traditional tube televisions. The first demonstration of the technology was during the 1980 Major League Baseball All-Star Game in Dodger Stadium, Los Angeles.
The first Jumbotrons used cathode-ray tube based technology, in which several sub-pixels were integrated into a module made of glass with a vacuum inside, with the shape of a block, in which each subpixel was individually controllable (addressable) with each subpixel acting as a flood beam cathode-ray tube Eventually this technology was replaced with LED technology.
Panasonic had the Astro Vision which was based on Fluorescent Discharge Tubes. These were the only three players in the large-screen industry.
In 1985, the term "JumboTron" was coined by Sony for its large-scale video board. The JumboTron was the brand 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. It 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. It was a microprocessor-based light bulb developed by one of Kuroki's colleagues, chief Betamax engineer Yuji Watanabe. Trini-lite technology allowed screen clarity and computer control, laying the foundation for the first Sony Jumbotrons.
In December 1986, the San Antonio Spurs unveiled the first indoor arena JumboTron scoreboard at the now-demolished HemisFair Arena.
While the JumboTron and similar large-screen displays are physically large, they ranged from low to medium display resolutions. While the original Sony JumboTron in 1985 had a 450,000-pixel resolution, comparable to standard-definition televisions of that era, certain later models had lower resolutions. The JumboTron at the now-demolished Tampa Stadium in Tampa, Florida, measured 30 ft (9 m) diagonally, with a resolution of only 240x192 pixels, below VHS resolution. Screen size since then varies depending on the venue. The display introduced in 1985 was 40 meters wide by 25 meters tall. Newer, LED-based large screens have resolutions that are an order of magnitude greater than the early JumboTron resolution at a fraction of the cost. For example, the much publicized center-hung video board in the Dallas Cowboys' AT&T Stadium is 72 feet tall and 160 feet wide (22 m x 49 m), displaying HDTV at 1920 x 1080 resolution, 45 times more pixels.
