OLED Screens
OLED Screens
Although not necessarily enineered at the nano-level Organic Light Emitting Diodes (Light Emitting Diodes (LED) whose emissive electroluminescent layer is composed of a film of organic compounds) have led to the miniturisation of many devices that require screens.
OLED systems are deposited in rows and columns onto a flat carrier by a simple "printing" process. The resulting matrix of pixels can emit light of different colors and can be used in television screens, computer displays, small, portable system screens such as cell phones and PDAs, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. OLEDs typically emit less light per area than inorganic solid-state based LEDs which are usually designed for use as point-light sources.
Because there is no need for a backlight, an OLED display can be much thinner than an LCD panel.
