1080P high-end home theater projector technology secret

High-end home theater projector has been a succession of projection technology, in addition to analysing the mainstream shows trends, high-end home theater projectors are also responsible for the projection products challenge other display technologies, thus the manufacturers will have the latest core chip, optical systems, color processing and data processing techniques applied to high-end home theater projectors, and as the technology matures and cost reductions, some of these technologies will be gradually applied to professional projector or commercial projector. 　 So high-end home theater projector to a certain extent, can represent a projection of future technological development. The following collection of long ago just concluded CEDIA (the Custom Electronic Design and Installation Association, a standard circuit design installation Association) annual Festival debut of some high-end home theater projector products, from which we can look to the future a break time projector technology development. LCD projector contrast breakthrough this exhibition a resolution of 1280 × 720 LCD projector is the most eye-catching, they all adopt a 1280 × 720 widescreen LCD Panel that can support 720 p high-definition video display. LCD projectors and DLP projectors in contrast targets, to some extent, affect its dynamic video display in high-end home theater projector-this is especially important. Here we introduce 4 at the CEDIA show LCD projectors in contrast there is a great breakthrough, all reached the 5000: 1, analysis of the reasons, in addition to the improvement of the LCD Board itself, these projectors are dynamic IRIS technology (dynamic iris) or dual IRIS technology (DUAL IRIS), the dynamic aperture technologies to dynamically adjust the light reaches the LCD Panel, to display a black brightness in the image, reducing the amount of liquid crystal panels light incidence, thereby ensuring the black image of blackness, improves the dynamic range of projectors, also increases the contrast. And the dual-diaphragm technology in LCD panels and rear all reproduced a set Aperture system, and LCD compatible light control, for high-contrast and dynamic range. Here are 4 at CEDIA debut of high-end home theater products. Sanyo PLV-Z4 (United States model, LP-Z4 Japan model) is a new upgrade, Z3 used dual aperture engine, 7000: 1 contrast ratio, brightness, 1000ANSI lumens has designed a 2 x optical zoom lens and a wide range of camera movement characteristics, you can not move projector cases move around the screen, above and below the maximum 3 pictures min (± 1 screen), or maximum 2 screen min (± 1/2 screen) and boost user installation ease and flexibility. Z4 featuring newly developed large-diameter, low noise sirocco cooling fan. Dramatically improves the efficiency of the heat inside the ontology, projector noise at work is also under control in 22 DB. Panasonic upgrades PT-AE900 is PT-AE700, using a fast dynamic aperture, dynamic gamma correction and dynamic sharpness control, you can complete within 1/60s automatically adjust screen. AE900 new LCD Panel and a new optical system, the implementation of 1100 lumens brightness, because of the dynamic variable iris range expanded so you can also achieve 5,500: 1 high contrast, images and other darker scenes, noise and black floating in a significant reduction in the performance of the black, dark detail section also features more detailed. In addition to the new AE900 smooth screen technology, such as cinema film image smoothing images in General. AE900 also follows the obtained in TH-AE700 projector praise of 2 x optical zoom lens, making it better. Hitachi UltraVision is Hitachi HDPJ52 launched high-end home theater products, 1200ANSI lumens of brightness and contrast of 5000: 1, also incorporates a dual Aperture system, is equipped with 10 gamma correction function. HDPJ52 equipped 1.6 x optical zoom lens, the camera can be moved horizontally and vertically, thus in the case of non-mobile projector can move around the screen and projector installation convenience. Hitachi PJ-TX200J is Hitachi in Japan in late October for the listing of a high-end home theater projector, it is equipped with 4 PCs ED (Extra low Dispersion) lens and New Wooo HI VSION lens. Consists of 13 groups of 16 pieces of the lens, with very high imaging performance. The camera's autofocus function called: SUPER FOCUS, for the center of the screen color display around some very bright place. PJ-TX200J projector brightness 1200 lumens, PJ-TX200J also incorporates a dual Aperture system that can deliver up to 7000: 1 contrast ratio, black floating phenomenon of suppression and enhancement of the black expressive. PJ-TX200J equipped 1.8 x optical zoom lens, the camera can be moved horizontally and vertically, thus in the case of non-mobile projector can move around the screen, you can move up and down direction 2.5 screen, you can move left and right direction 1.5 screen. 1080P DLP looks forward to the CEDIA's most attractive DLP projector is Mitsubishi HC3000 introduced, this resolution is 1280 × 720 projector using TI's HD2 + chip, its brightness DarkChip3 as 1000ANSI lumens, 4000: 1 contrast ratio for, this is the first use of the TI Jizhise color technology (BrilliantColor) product that enables single-chip DLP projector color performance to a new level. Samsung also introduced two 1280 × 720 DLP projector, which introduced HD SP-H710AE2 + chip, contrast to 2800: 1; SP-H800BE use newer HD2 + chip, the contrast is not DarkChip3 3800: 1. Sharp's XV-Z12000 Mark II is a Sharp last year XV-Z12000 alternatives, it uses the HD2 + chip DarkChip3, also adopted 5 x 7 segment color wheel, contrast from 5500: 1 to 7000: 1, brightness from 900ANSI lumens to 1000 ANSI lumens. In addition to 720 p products, there will be a monolithic 1080 DLP TI has been delivered to the manufacturer, before the vote in their own development all of optical, electrical and other components. New 1080P chip born Dark Chip 3 platform, in addition to the increased resolution, all the physical characteristics and now best 720P machine Basic equivalent, it is estimated that by the mid-2006, see the appropriate single-chip 1080P DLP projector 1080P front projector, which will have more choices. Today announced that it will in future use DLP 1080p technology manufacturers: Barco, Visual, Digital Projection International, rich visual, Marantz, Mitsubishi, Panasonic, Optoma, projection design, international audio (Runco), Samsung, sharp, SIM2, and Yamaha. 10000 SXRD projector $ Qualia are home theater projector in Ferrari, with its noble status symbol of high prices and high-performance, CEDIA, Sony announced a new low-priced version of Qualia-004 home theater projectors – VPL-VW100, it incorporates Sony's SXRD reflective LCD technology, is expected to be in the month of December of 2005 or 2006 1 month listing, the listing price of $ 10000. VPL-VW100 adopts Sony newly developed 0.61-FULL HD SXRD panels (1920 × 1080 pixels) and with the Sun's ultraviolet characteristics similar to 400W PURE xenon lamp. Projector lens incorporates a clear projection image ARC-F HI VISION (ALL RANGE CRISP FOCUS) lens. Use the image brightness and darkness for automatic light high aperture of conciliation (advanced iris), can achieve up to 15000: 1 contrast ratio, but now on this contrast nominal, the industry has some controversy, and there is a saying its actual contrast in about 3000: 1. This machine uses Sony's latest design of cooling systems to effectively reduce noise, noise VPL-VW100 work has effectively under the control of 22 DB, for the user in a very quiet and enjoy the environment.
