A Jumbotron is a video display using large-screen television technology. The original Jumbotron was developed by Sony, and is typically used in sports stadiums and concert venues to show close up shots of an event.
Flood beam CRTs differ from a normal CRT in that the electron gun within does not produce a focused controllable beam. Instead, electrons are sprayed in a wide cone across the entire front of the phosphor screen, effectively turning an image display device into a single pixel. This display contains multiple flood beam devices in a single envelope, enough to display eight pixels of RGB data. Hundreds of tubes such as this are required to build an entire Jumbotron display.
