Diskless Computer
No disk drive (DISK DIRVE) a computer, usually connected to the network (NETWORK), the operating system from the server to provide (OS) and application and file services, there are lower costs and centralized management of benefits, but the server burden will increase.
Dithering Graphics
Network indicated that the use of different size and shape of the limited color point combinations to make the naked eye have different shades of color change in graphics.
DLC Data Link Control

DLP (Digital Light Processing)
DLP projection light is projected through the principle of high-speed rotation of the red, green and blue (white) color wheel and then hitting the DLP chip reflective imaging.
With the progress of the times, the display screen size requirements with the upgrading of computer monitors from 12 inch size, 15-inch reach 17 inches or larger size, the 30-inch TV is also back into the general products, we The pursuit of an even more comfortable picture. Breakthrough shows that the bottleneck size, in addition to plasma TVs, the projection mode is the current mainstream, while the DLP, and it is a rising star Lcos projectors that can meet future trends.
Because Panel itself does not glow, is to use light to light and Panel’s image, and then out of the projection lens to image projection. 3 Type DLP projector is to use diachronic mirror (Diachronic Mirror) to do spectroscopic work, and three have been absorbed, then up through the three primary colors of the images overlap the projection lens projecting out. It can be seen clearly in a good efficiency in the use of light, each point is a full-color point, the screen resolution on the increase, that is, better picture quality.
RGB is to use the coating components to its spectral distribution are likely to be on our need to design, which makes three-piece type of DLP projector color saturation, higher levels of feeling good, natural colors. DMD board using small size can make the optical system along with the smaller, so the optical components used are also smaller, which has shown is more easy to produce low-cost access to parts sources, rather than the performance of the system is smaller, more light system.
Pictures in the projection data must be made whole as much as possible the average brightness of the screen. To achieve this purpose, in the system using the lens array plate (Lens Array Plate) to generate the homogenization effect. In the optical engine body all the optics, light machine parts and components, as have been transferred to manufacturers for mass production, domestic supply will be sufficient. |
