An OLED display works without a backlight. Thus, it can display deep black levels and can bethinner and lighter than a liquid crystal display (LCD). In low ambient light conditions such as a dark room an OLED screen can achieve a higher contrast ratio than an LCD. OLEDtechnology is used in commercial applications such as displays for mobile phones and portabledigital media players, car radios and digital cameras among others.
