Learning about how far this technology has come will help you appreciate the potential of the LED future. The history of LED display technology dates back several decades. Still, it took ages after its invention to go mainstream. 

LED display technology was invented thanks to the concept of electroluminescence which dates back to the beginning of the 20th century (1900s). Notable figures like James Mitchell altered the course of the industry years later. This was after Mitchell developed what can be considered the first true LED screen in 1977.

Early applications of LED displays

Applications of LED displays have evolved with the technology. In the early days, people used it in various ways. While most of the early uses have disappeared, some of them remain to date. Some of the early uses include;

  • Electronic scoreboards. In the 70s and 80s, developed regions used LED displays in arenas and stadiums as scoreboard displays. This replaced the electro-mechanical displays which used incandescent light bulbs for lighting. This marked a turning point for large LED displays.
  • Digital signage. This is a common application of modern-day LED displays but it emerged decades ago. LEDs used for early digital signage were of low quality. Yet, it paved the way for modern digital signage technology.
  • Screens for handheld devices. Several gadgets like mobile phones, toys, and other electronic devices used screens made using LEDs. Specifically, the dot-matrix display technology was used to make these screens. This display technology is well suited for screens that display alphanumeric characters and rudimentary graphics.
  • Message boards and signs. The adoption of LED displays in the advertisement space started way back. Advertisers used large screens mostly for outdoor advertising in places like town centers.

These early applications ushered in a new era of LED display technology. Since then, visionaries invested resources to improve the technology. If anything, this tremendous investment is one of the reasons why this technology became widespread.
