Pantalla LED (light-emitting diode) displays are everywhere these days. From our TVs and smartphones to billboards and traffic lights, LEDs are changing the way we see the world. But what exactly are LEDs, and how do they work?
LEDs are semiconductor devices that emit light when an electric current passes through them. They are made from a variety of materials, including gallium arsenide, indium phosphide, and aluminum gallium arsenide. The color of the light emitted by an LED depends on the material used.
When an electric current passes through an LED, electrons in the semiconductor material are excited and move to a higher energy level. When the electrons return to their original energy level, they release energy in the form of light.
LEDs offer a number of advantages over traditional light sources, including:
LEDs are used in a wide variety of applications, including:
LEDs are still a relatively new technology, but they are rapidly becoming the dominant light source in a wide variety of applications. As the cost of LEDs continues to decline, we can expect to see even more innovative and creative uses for this versatile technology.
Here are just a few of the ways that pantalla LED can transform your life:
Pantalla LED is a versatile and energy-efficient technology that is rapidly changing the way we see the world. As the cost of LEDs continues to decline, we can expect to see even more innovative and creative uses for this transformative technology.
| Table 1: Advantages of LEDs over Traditional Light Sources |
|---|---|
| Characteristic | LEDs | Traditional Light Sources |
