Panasonic DLP projector --DW7000/D7700 series of ultra-high contrast ratio

Aperture layer 256, when the projected light image signal for the white scenes, the dynamic cutting machine is fully open, so full of light projected onto the DMD chip above; and when the projection of the image signal is black scenes, the dynamic cutting machine is completely closed, At this point the core DMD signal level in Figure 2 (real-time gamma curve graph) no light on-chip video technology. Through this principle, the dynamic cutting machine on the projected image signal in real time control, resulting in a high 4000:1 contrast ratio. Can be seen from Figure 2, the projector's gamma curve normal to a linear line, and the use of dynamic cutting technology of the projector to obtain a flexible dynamic gamma curve, greatly improving the image projector details reproduction capacity. DCI Alliance in the United States prepared the draft standard digital cinema version 4.0, provides the depth of the projector's color reproduction is not less than 45 bits. Panasonic D7700 series, Panasonic professional image inherited the advantages of technology, to reach 48-bit color depth, which can be projected with the film quality is superior picture quality. At the same time, we know that because of the dust pollution in light path system, will cause the overall brightness of the projector 5 to 1O decline. To avoid this loss of brightness, Panasonic bulb, prism, DMD chip, the lens group, which is a set of optical system design has become fully enclosed dust optical system, making the projector even after running for a long time to maintain a high brightness and high picture quality. 9 bulbs 1ONl bulb lamp 2ON 1ON -,,,, a,,,, 9, one by one \Figure 3 magic bubble will continue to alternate use, both to ensure they use high-density, and extended lamp life as a film screening for the requirements of system stability is very high, once the screening process are any questions, the audience is not possible In the film inside the waiting room; the same, not just movies, including some large-scale monitoring systems such as traffic management centers, power control center, and so these places are not allowed any interruption, and Panasonic's unique dual-lamp system a good solution to this problem. Cold light source through the use of two light bulbs, has greatly increased the stability of the projection system, a problem when one light bulb does not work,[link widoczny dla zalogowanych], the other bulbs are still able to work, keep the system running. Another special feature is the dual-lamp system, bulbs turn delay functions, as shown in Figure 3. Over time, the lamp 1, the power slowly decreased, while the lamp 2, the power gradually increased over time, both the total brightness of the lamp output is always maintained at a constant quantity. This description and analysis of the work equipment] Factory 1IolSourcel multi-image processor with edge stitching stitching functions did not use the edge of pine F Figure 4 more than a round face unique processor,[link widoczny dla zalogowanych], seamless stitching, perfect color matching, making the two bulbs to avoid for a long time in high power mode, thus greatly increasing the use of time, to extend the life of the bulb so that users can really enjoy the low-cost operation. In special projects such as the large movie screen, stadiums, three-dimensional movies, usually more than 2 sets of simultaneous projection projector; some need for wide screen splicing, such as the movie screen needs stitching 9 images; Some of you need to project three-dimensional image. In these special applications, whether it is wide screen projection mosaic, or three-dimensional images, stitching edge of the screen are required to perfect, exactly the color of each screen. Panasonic has accumulated on the basis of years of experience, in particular, developed their own unique multi-image processor, making the D7700 series to achieve the perfect edge stitching and color matching. Color gamut of each projector is a certain difference, multi-image processor via a 3-color adjustment method,[link widoczny dla zalogowanych], and 7 color adjustment method to carry out multi-projector color matching adjustments. This simple method of adjustment of 3-color instructions. 3-color adjustment method is through the red,[link widoczny dla zalogowanych], green, and blue in color gamut graph coordinates to adjust, first dedicated colorimeter with a projector on the red, green and blue were measured, and then the measured data into the color manager for operations, and through the RS232 port to the results of operations in the input to the projector automatically adjust,[link widoczny dla zalogowanych], and so on, eventually get a different projector's red, green, blue coordinates degree intersection, in order to achieve color matching. The edge of the edge stitching is used to reduce or increase the brightness level is outside the edge of the brightness level of the rest of the methods to achieve. It is because with a dynamic cutting technology, dual-lamp turn delay, improve the multi-screen processor, making high-end Panasonic DLP series can be used in a variety of special occasions, and to project the perfect high-quality, high-definition screen.
