The projection technology is the way the projector's lamp light is converted into an image to be projected through the lens onto a surface. This particular one is LCD technology and its lamp is LED type, which has a longer lifespan but lower brightness than regular lamps, with good color performance.
This technology gets its name from the initials of the words Liquid Crystal Display. The image is created by a liquid crystal panel which produces combinations of the three primary colors: red, green, blue. This results in very good color performance even in black.
