An electronic gadget that is used as a very efficient source of light is called light emitting diode or LEDs. These diodes are used to make up a video display screen which is referred to as LED display screen. LEDs are used in daily devices ranging from remote control to traffic lights. LED screen is also utilized in shop signs and signboards.

LED panels are utilized for lighting instead of showing functions. An LED panel consists of variety of LEDs and a normal LED display screen consists of many LED panels. Surface mounted device (SMD) panel and traditional LED panel are the two classes of LED panels found in the market. The standard panel uses discrete LEDs which are used specifically for screen screens in big outdoors. Conventional panels are more typical as compared to others and in this type of panel, the cluster of LEDs of various color are organized to form a square-shaped pixels used for displaying.
The LED screens which are used indoors utilize SMD innovation. SMD technology uses red, green and blue LEDs in panel which are themselves utilized to form lighting and illumination but not for display screen. Pixels are formed mounted over circuit boards and chips. The pixels formed are smaller sized than a pinhead. For that reason in SMD, the optimum seeing range is reduced as well as there is slight decrease in the brightness. The both above discussed included make the SMD innovation better for indoor applications.
The LEDs used to make up an LED display screen are among the most important technologies of electronics. The light giving off diode offers numerous advantages over other light releasing sources. This diode is made of a semiconductor chip surrounded by the transparent plastic case. The plastic case enables the light to pass through it. As favorable and unfavorable terminals of the diode is connected to the supply, the electrons begins following through the semiconductor due to its chemical nature. The accident of electrons discharges energy through photons or light. The emission of different colors consisting of infrared and ultraviolet light depends on the semiconductor product utilized in the diode.
Nowadays, LEDs are chosen over traditional source of lights due to many benefits over them. In standard source of lights a large amount of heat is produced and nearly half of energy is lost through heat. On the other hand, LED consumes very less energy and extremely less quantity of heat is produced as compared with traditional light sources. These are the reasons for which the LEDs are utilized in traffic lights and all other devices.
