Introduction
A videoboard, also known as a jumbotron or video display board, is a large screen used to display live video feeds and replays at various events, primarily in sports arenas, concert venues, and public gatherings. The primary purpose is to enhance the spectator experience by providing clear and magnified visuals of the action or event.
Historical Context
The concept of videoboards dates back to the mid-20th century, with significant developments occurring in the late 1970s and early 1980s. Sony’s introduction of the JumboTron in 1985 marked a milestone in display technology, revolutionizing the way live events were experienced.
Key Events
- 1985: Sony introduces the JumboTron at the World’s Fair.
- 1996: The development of LED technology significantly improves resolution and brightness.
- 2000s: Videoboards become standard in major sports venues.
Types/Categories
By Technology
- CRT-Based Videoboards: The initial technology used, now largely obsolete.
- LED Videoboards: Modern standard, offering better clarity and energy efficiency.
- LCD Videoboards: Used in smaller applications where high resolution is essential.
By Usage

Detailed Explanation
Videoboards consist of multiple panels, each containing numerous small light-emitting diodes (LEDs) or liquid crystal display (LCD) elements that work together to form a cohesive image. The integration of real-time video feed technology with these screens allows for dynamic and engaging displays.
Mathematical Models/Formulas
While specific mathematical models are less prevalent, the technical design often involves calculations for resolution (pixels per inch), aspect ratios, and optimal viewing distances.
