Short of magnificent
Remember 03 sumisho dual concept surfaced, the impact on the market can be described as minimal, it is one of the products. But in 2004 the "5 + 2" multi-functional projector groups but have achieved rapid growth and become an independent product categories, it has a large capacity and good growth momentum, has already become the projector market competition, all the manufacturers of the bridgehead are all involved in this area. As BenQ PB6105, rich visual EMP-S1 X1, Epson, Hitachi and NEC VT46 HS800, are very classic + products. Input from the technical point of view, the sumisho dual-use goods is not a simple concept of speculation, in order to adapt to the needs of home video, many products in contrast, the colors are more emphasis on the some manufacturers also applied a TI latest DDR-DMD chip to enhance the contrast, such as Toshiba's palette technology; manufacturers are by virtue of their technical superiority, and continuously improve the picture quality, such as Hewlett Packard's double-wheel technology, Association of Zeiss optical system and so on. But let us puzzled: 05 is near the end of the age has scenery infinite sumisho dual purpose but no major achievements, last year's beautiful dream seems to have become a mirage. The reason I think sumisho dual failure to locate unknown, difficult to reach home projector ban!
Fetched home
Bold looks, sumisho dual-use products involved in commercial and home to two major areas of expansion of the scope of the application seems to be able to bring to market growth, but it only work when positioned on entertainment, leisure, simply cannot keep very important video effects of domestic demand. These so-called "commercial and residential" and not a real video projector, though some of the technical indicators, such as brightness, contrast, resolution, and so looks very high, also set up such as videos, games, theater, and many other preset projection mode, but its inherent low-end commercial origin so that it is difficult to achieve in the household good theater.
First of all, business applications focus on brightness, but on the shade of a better home for high brightness means "scapegoat". High brightness while in light of strong environment continues to be bright, but there is no contrast levels of the picture, the movie is very difficult to show the details, but in a small space watch too light screen on sight is very negative.
Secondly, contrast, resolution is close to the mainstream. Many DVD movies are darkened presentation, only the high-contrast to Dim the screen displayed the scenes. Resolution, the larger the picture quality is fine, but the zoom screen multiples, still you can get very good results, most household projector physical resolution have already reached a level of 1280 × 720, sumisho dual-use goods are mainly in 800 × 600.
In addition, the use of the component from the projection, a business-oriented live ' dual-use products rarely set specifically for the video image optimization technology and hardware support. In particular, DLP projector, many were ordinary three color wheel, the projection process can have serious effects on the Rainbow, unacceptable.
Finally, there are 4: 3 and 16: 9 selection problem, although the majority of sumisho dual-purpose product support 16: 9 and 4: 3 dual display mode to switch freely, but the default projection mode is 16: 9 format products in order to obtain better widescreen effect. If to look at the DVD blockbusters, choose screen horizontal vertical ratio of standard 16: 9 products. But for Office users, 4: 3 ratio is more appropriate.
04-year household products have not only reduced, but expensive, sumisho dual-use goods is without doubt the most economical entry-level product for household use, but nowadays million-level home new products come out, if stress again that such products are suitable for families, choice had some unkind, to better referred to as the "5 + 2" business machine more accurate: positioning in the business, occasionally brought entertainment.
Applicable on the rise
04 sumisho dual-use products quickly introduce the projector market, but rather for household use is controversial performance makes home projector has been difficult to settle until 05 all manufacturers have implemented real positioning in household products, ordinary consumers only on household projector has a more comprehensive understanding of reason.
In addition to look stylish, feature-rich and operations increasingly humanistic, household projector and commercial product most essential difference from the hardware configuration: This includes a dedicated processing chip, image color optimization system, faster video processing system to reduce picture noise and increase the picture detail image system, etc. In addition, household projector to be equipped with a DVI interface or color interface, upscale home projector should also be equipped with an HDMI interface, connection of HD signals. In General, the ordinary DVD format as 480p (resolution of 720 × 480), low end projector mostly can be lossless projection out DVD image screen, but the user projection HDTV if you want to cast or HTPC's 720p (1280 × 720)/1080i (1920 × 1080) signal, it is best to use in high-end home theater projector. In addition, China General House space, short focal projection should be the preferred solution. The general public more with energy-saving automatic standby, quality, a key energy, not only
You can reduce energy consumption, but also to extend lamp life, in addition, the application for a long time on the family is more prevalent, so home projector in improving cooling efficiency, reduce noise generally have a special design, as is now mostly maintained at 30 DB.From a product perspective, in addition to the built-in DVD player auto code DV10 and zone air purification function Optoma H27 and so these constantly updated new household concept, not only for domestic market 05 products increasingly rich, and product line has been formed, such as the low end market with EPSON AE700 EMP-TW10H, Panasonic, Sanyo PLV-Z3 and rich visual ScreenPlay 4805; mid market have SHARP XV-Z201E, Epson EMP-TW200H, rich visual Screenplay 5700; high-end market with EPSON EMP-TW500, rich visual ScreenPlay 777. It can be said that from the perspective of product coverage, comprehensive domestic market has 05 activation, the wait is only for purchase of consumer jingpenshi.
Power into the body to return
From a business perspective, sumisho launch of dual-use goods is only an attempt. For ordinary household consumers, the price factor has been the purchase of important reference conditions. With the projector prices, plus a big screen projector unmatched, more consumers purchase home theater was gradually will look to the projector. But the past video projectors are prices, merchants are not likely to stick a follow up, so it has a price advantage of low-end business projector nature became best way stone. Design changes, deliberately copying some features, such as can improve business efficiency in the use of the projector and can stimulate the home entertainment market of commercial and residential projector is born.
Is not to say that business notebook does not have to play a DVD, but for a primary purpose as entertainment for the home user, hardware configuration, functional aspects of the business notebook simply unable to meet demand. Similarly, sumisho dual-use projector is not available for entertainment, but simply recommended for home users to create theater atmosphere was a bit wrong. Sumisho dual-use products initially aimed to stimulate home entertainment, and is not intended to meet family entertainment, but domestic market is activated, this kind of product that is right, this is why as 05 household products emerge, sumisho dual-use goods no longer favor.
Some say that the sumisho dual-use projector to its good price/performance will increasingly gain market recognition, and the Yuan development trend is becoming increasingly apparent that two to three years after 8000 will become mainstream. Grounds that Epson, InFocus, Sony, Hitachi, has launched the corresponding product, many manufacturers also for its economy has been specialized in product design and product besides LCD products, but also increased the DLP products, etc. But I need to emphasize that whatever the sumisho how to upgrade to dual-use products, are unable to shake off its inherent low-end commercial origin, in front of real household products can only be a business application development, we cannot have a DVD drive is that all of the notebook is entertainment!
Putting aside the performance gaps, if you really want to live ' dual-use fully meet the two requirements miniaturization of products, so is the inevitable trend of development, the family moved to move to the outside. But the projector is a high power product, running process to produce a large amount of heat, due to space limitations, it is not possible to design more effective thermal wind fan formation, will inevitably bring road, product reliability, especially the life of the bulb will greatly reduce the cost, high late will be appended to the home users of men. Second, in order to compensate for the effects of space on the heat, Mini projector mostly increased fan power, greater noise, no quiet audiovisual environment create a cinema-grade on Ho? home entertainment market need for products to stimulate the sumisho credit of dual-use projector, but in a real location in household products have been relatively rich today, still advocating such products can handle household, individual businessmen passion seems to have been ambiguous, because it is precisely these businesses in 2005 as we demonstrated the kind of product is suitable for home use!
Summary
Two years ago, the projector for the vast majority of ordinary users also completely out of reach of the product. The price at $ 3, complex adjustments and quite delicate character make projector can only appear in the application in the industry, many SOHO users and home users while on the big screen effect really grateful, but still waiting for the best buying opportunity.
03 projector areas significant change in the level of economical projector $ broke the price breakthrough 04 and rapidly growing sumisho dual-use products for the first time let ordinary consumers see the hope of building their own home theater. Although 05 actively follow up of household products to sumisho dual-use projector lost glory of the past, but we know that today's business people will no longer be a boring office environments, work of leisure and entertainment has become the business market, a trend.
On private enterprises, and to spend double the money at the same time buying commercial projector and household projector, buy apartment dual-purpose machine more beauty, so do the qi, the "5 + 2" product still has a better tomorrow!
