A display screen that uses carbon-based film between two charged electrodes is called an OLED. When an electrical current is applied, a bright light is generated. OLEDs are lightweight and durable. They are ideal for screens on portable equipment. Since the OLED emits light, it does not need to be backlit like an LCD (Liquid Crystal Display) screen, resulting in improved power efficiency. OLEDs also offer fuller viewing angles and greater brightness than LCD displays.
