OLED
OLED stands for Organic Light Emitting Diode. A diode is an electric conductor in which electricity can only flow in one direction. A light emitting diode is a diode that lights up when electricity is passed through it. OLED displays are made of millions of little LEDs. Each LED has one of 3 colours: red, green, or blue. An OLED display will apply electricity to the different LEDs to produce many different colors. By doing this with all of the millions of pixels, the display can produce pictures. OLED displays have a few advantages over LCD displays. Because OLED displays don’t require a backlight, they can be made much thinner. OLED displays also require less power and the pixels in an OLED can react quicker than those in an LCD. “Organic” in this term comes from chemistry and means that the LED is made of carbon-based materials.
