When did LED displays become popular?
With the continuous advancement of modern technology, LED display screens have become more and more widely used. So, when did the LED display become popular? This requires analysis from a historical perspective.
As early as 1962, a scientist in the United States invented the first infrared LED, but people did not know about it at the time. Until around 1970, LEDs were widely used in computer robot lights, night lights, and digital clocks. The field of image display has gradually developed from monochromatic LEDs to colorful RGB LEDs. Especially after the 1990s, LED display has become one of the main forces of large-scale outdoor advertising.
The popularity of LED display screens was only gradually amplified in the early 21st century. With the continuous development of science and technology, technologies such as LED drive and LED signal processing have been greatly improved, the resolution and color depth of LED screens have gradually increased, and new products such as transparent LED screens and flexible LED screens have appeared. These technological innovations greatly improve the visual effect and practicability of the LED display, thus boosting its popularity of the LED display.
In addition, with the advent of the Internet era, the intelligence of LED displays has become a trend, and various hardware and software technologies have been iteratively upgraded, from traditional steel frame advertising screens to current multi-functional digital displays, interactive screens, etc. In the future, with the continuous advancement of technology, LED displays will be widely used in more industries, and the beginning of this change is at the end of the 20th century and the beginning of the 21st century.
