what is oled display

An OLED display is a type of display technology that uses organic light-emitting diodes to produce light. OLED displays are made by placing a series of organic thin films between two conductors. When an electrical current is applied, a bright light is emitted. OLED displays are emissive displays, which means that each pixel is controlled individually and emits its own light, unlike LCDs in which the light comes from a backlighting unit. OLED displays can achieve deep black levels and can be thinner and lighter than LCD displays. They also have a higher contrast ratio than LCD displays in low ambient light conditions. OLED technology is used in commercial applications such as displays for mobile phones, portable digital media players, car radios, digital cameras, and laptops among others. OLED displays feature great image quality, bright colors, fast motion, and most importantly, very high contrast. They also enable flexible and transparent displays.
