The initial application areas of LED display screens can be summarized as follows:
1. Indicator light source for instruments and meters:
LED display screens were originally used as indicator light sources for various instruments and meters, such as micro indicator lights for high-end equipment such as computers, audio and video recorders.
2. Traffic lights:
With the advancement of technology, LEDs have begun to be widely used in traffic lights. For example, taking a 12-inch red traffic light as an example, LED light sources have significant advantages in power consumption and light efficiency compared to traditional incandescent lamps.
Automobile signal lights are also an important application area for LED light sources, especially in high-mounted brake lights, where the fast response speed of LED helps reduce the occurrence of rear-end collisions.
3. Outdoor billboards:
Although it was not the initial direct application area of LED display screens, with the maturity of technology and the reduction of costs, LED display screens have gradually been used in outdoor billboards, especially in large squares and commercial advertisements.
4. Other special areas:
LED display screens have also been used in outdoor red, green and blue full-color display screens, keychain-type miniature flashlights and other fields, demonstrating their wide adaptability.
In summary, LED display screens were initially mainly used in the fields of indicator light sources and traffic lights for instruments and meters, and then gradually expanded to outdoor billboards and other special fields.
With the continuous advancement of technology and the reduction of costs, the application scope of LED display screens has become more and more extensive, becoming an important part of the modern information display field.
