An electronic device that is used as a very efficient light source is called a light-emitting diode or LED. These diodes are used to create video displays known as LED displays.
LEDs are used in everyday devices, from remote controls to traffic lights. LED displays are also used in shops and billboards. You can also buy led display screen through various online sites.

LED panels are used for lighting, not for display. An LED panel consists of several LEDs and a typical LED display consists of many LED panels. Conventional panels use discrete LEDs specifically for large outdoor screens.
Conventional panels are more common than others, and in this type of panels groups of different colored LEDs are grouped to form square pixels used for display.
The LEDs that make up the LED display are one of the most important electronic technologies. Light-emitting diodes offer many advantages over other light sources. These diodes consist of a semiconductor chip surrounded by a transparent plastic case. The plastic housing lets light in.
When the positive and negative terminals of the diode are connected to the power supply, electrons begin to follow the semiconductor due to their chemical properties.
Electron collisions emit energy in the form of photons of light. The emission of various colors, including infrared and ultraviolet light, depends on the semiconductor material used in the diode.
Today, LEDs are preferred over traditional light sources because of their many advantages. Conventional light sources generate a lot of heat and almost half of the energy is lost in the form of heat.
