WebAs mentioned earlier, LCDs rely on a backlight to illuminate the display and its pixels. This has been the case since the first created LCD in the 1960s. For decades after, displays were rather limited in size and resolution. Colors were not as dynamic. In the 1980s, larger-scale displays were made, such as the first 14 inch full-color TFT LCD. Web6 de set. de 2006 · OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted.

A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. LCDs are … Ver mais Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of Indium-Tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes … Ver mais Since LCDs produce no light of their own, they require external light to produce a visible image.
