The type of technology to do with entertainment that is featured here is the Jumbotron
A Jumbo Tron is a large-screen television. The Jumbo Tron uses technology developed by Sony, typically used in sports stadiums and concert venues to show close up shots of the event or events. Sony Jumbo Trons ceased being sold in 2001, when the company decided to exit the business.
Design
Manufactured by Sony, the Jumbo Tron is recognized as one of the largest non-projection video displays ever manufactured in the world. Originally, it was not an LED (light-emitting diode) display. It had each display consisting of multiple modules composed of 16 or smaller flood-gate CRTs (cathode ray tubes), each of which included two to 16 pixels composed of green, red, and blue phosphors. Sony creative director Yasuo Kuroki is credited with the development of the Jumbo Tron. Eventually, even Jumbo Tron Systems adopted LED technology as it phased out CRT based systems. LED based systems have about 10 times the lifespan of CRT based systems, a key reason for the changeover. This lifespan helps save money and time.
Deployments
One of the largest eight-sided (octagonal) Jumbo Trons in the world is in Dallas, Texas, USA. The largest non-octagonal Jumbo Tron is located at the Atlanta Braves Turner Field and the largest one for a high school in the USA is located at Lassiter High School in Marietta, Georgia. While the Jumbo Tron and similar large-screen displays are physically large, they were often low in display resolution. The Jumbo Tron at the now demolished Tampa Stadium in Tampa, Florida, USA, measured 30 ft diagonally with a resolution of only 240×192 pixels. 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 2 or 3 times this early Jumbo Tron resolution at a fraction of the cost.
The largest Jumbo Tron in use was located at the Rogers Centre (then called SkyDome) in Toronto, Ontario, and measured 10 m tall by 33.5 m wide (33 ft. × 110 ft.) at a cost of US $17 million. By comparison, a similar sized LED system sold today would cost around $3.0M. The Rogers Centre Jumbo Tron was replaced in 2005 by a Daktronics ProStar as a part of a stadium revitalization project which led to more money to the Daktronics ProStar company.
Future
The future for this jumbotron is a very bright, good future. It will become a very popular and efficient screne for arenas and the like.
