Multimedia Projection System
Multimedia Projection System
System description : A projector or image projector refer to an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens, but some newer types of projectors can project the image directly, by using lasers.
System Operation flow : In a DLP display, tiny mirrors are used instead of transparent panels. Each mirror represents one pixel. The light, rather than passing through the panel, is reflected from it. The mirrors move back and forth, varying the amount of light that reaches the projection lens from each pixel. Color is obtained by passing the light from the lamp through a rotating wheel with red, green, and blue filters. This subjects the mirrors to light at each of the primary colors in a rapid rotating sequence. The result is a color-modulated image that the human eye sees as natural color.
System application location : cinemas, hotels, airports, shopping mall, commercial building and railway/LRT/MRT/KTM waiting area.
