Projectors Home

Today, the situation changed the other way around. In the segment of large diagonals already superb plasma tv at a very affordable price. The operating principle of a plasma panel based on the special glow of the phosphors, located in the smallest cells of the screen. These luminous cells and are the pixels that make up the image. The main problem of the plasma technology have always been a big pixel size and, consequently, low screen resolution.

Development in this direction was going very slowly, but today the problem has been solved – appeared on the market model, capable of pixel density to compete with lcd devices. However, plasma TVs continue to occupy a large segment of the diagonals. Among the main advantages of plasma displays to mention the high real contrast, deep color and wide viewing angles. Projectors Home appointment of projectors – the formation of very large-scale image of the diagonal in the framework of a home theater. Objectively, the projectors are the highest quality display facilities, but we can not discount the complexity of their installation and the need to provide room darkening. Recently projectors as a home remedy gaining increasing popularity in the world. Contributes to this in the first decline in their value, as well as a new trend – cheap and easy to use presentation models are good for use in everyday life.

Synonymous with an lcd projector that has become almost an acronym 3LCD. The technology is very simple – the image is formed on the lcd matrix. which works on clearance. 3LD-method differs in that the design, there are three matrices (the three primary colors RGB), a special system of mirrors and prisms, meets three Light streams into one. As any luminal way to create images 3LCD peculiar low level of real contrast, and not all models of this problem is solved. dlp – technology is a fundamentally different type. Here the image is formed using micromirror matrix, and the light reflected from it passes through a rotating color wheel. Thus, one frame is divided into several phases of colors that are displayed on the screen sequentially. This technology has a number of specific features – work on the principle of light reflection provides a high level of self-contrast, and the participation of a rotating color wheel to create the image provokes the appearance on the screen glowing trails and paths. With the reclassification of the projector, this problem pales into insignificance, but completely get rid of the rainbow effect is possible only by applying trehmatrichny method, in which static color filters are utilized. However, in this case the value of DLP-projector is far higher than comparable lcd models. LCoS-technology is more commonly known under the names of data it manufacturing companies: D-ILA in Technology jvc and sxrd at Sony. According to the principle of its action as it combines LCoS other technologies. Matrix reflects light from the lamp, but the image is formed coated with a layer of liquid crystals. This method is today technically exceeds the more common 3LCD and dlp, but it is much more expensive and therefore only used in high-end models.
