Projector technology types and specifications
LCD Technical Specifications: LCD projector product structure,
performance and cost requirements, LCD panels with different sizes. LCD
liquid crystal panel size determines the size of the projector, the
smaller the LCD liquid crystal panel Unit, the optical system of the
projector can be made the smaller, so that the smaller the projector.
But to achieve high resolution on a small LCD, and maintain a high
brightness, and the difficulty of its technology can be imagined.
0.9-inch and 0.7-inch panel production, the ratio reached 70%, the
proportion of 1.3 inches in about 15%, 0.5-inch, 0.79-inch, 0.99-inch
and 1.0-inch panel for projector products. On the number of liquid
crystal panel, since the monolithic structure in the aspects of
performance and color defects is substantially eliminated. Mainstream
3-LCD projector, outstanding performance in terms of performance and
color in a very long time, and represents the most mature level of
projector product development. In the case of the same brightness and
resolution, the the projector smaller the size the higher the price
corresponding.
DLP Technical Specifications: LCD technology, the DMD chip size is an important factor to determine the size and weight of the projector, and Texas Instruments also introduced 0.55 inches, 0.7 inches, 0.9 inches and 1.1 inches of a variety of sizes chips. DLP projector, the most common structure of single-chip and three-two, three-structure theater systems and high-performance products are mainly used in the ordinary application of the common market, all the products are monolithic structure, people comparison of general talk about DLP technology and LCD technology, mainly based on the comparison between the single-chip DLP technology and 3-LCD technology. The single-chip DLP projector dichroic color wheel to achieve three primary colors with the same imaging components, compared with the three primary colors have imaging system 3 LCD projector, single-chip DLP projector in color saturation has been than three LCD projectors difference. The first generation of DLP projector color wheel speed of 60Hz, second-generation DLP color wheel speed doubled, still 120Hz to 120Hz, the next generation of DLP projector color wheel speed, but the color wheel with 6 separations (3 separations), equivalent to improve the speed and doubled, reached 240Hz. Current DLP projector color performance has been greatly improved, but compared to LCD products, the products of most of the single-chip DLP projector color performance is still lagging behind.
