LED - definition
LED is a semiconductor device that can convert electrical energy to optical energy (if a specific amount of voltage is applied and current passes through the semiconducting material). It is a kind of one-way switch and that is why the full form of LED is Light Emitting Diode (one-way switch). In today’s generation, LED is one of the most used devices in technology. Based on the type of semiconducting material used in an LED, the color of the emitting light can be changed to a particular value. Generally, an LED has only two pins that are used to supply power to the device, called Anode (positive side) and Cathode (negative side).
LEDs can produce both visible and infrared light with different wavelengths. It is used in so many devices such as remote control, flashlight, display panel, for backlighting, and so on. Smartphone manufacturers started providing LED displays in many types such as OLED, AMOLED, sAMOLED, QLED, and a few others. In-display technology, LED is the most preferable at current state because of its low power consumption, less heat generation, and faster refresh rate. Also, LEDs can produce more accurate colors than LCDs. After years of research it came up that LED is also better for the eye as well compared to LCD or CRT display technology.
