End of the year is the year, a year's hard about the wind. Get year-end bonus of people are wondering how to "reward" the following own. For those who Film Fans, HD fans, buy a home projector, a component of a home theater is definitely a good idea. Home Projector products in recent years, prices continued to decline, no longer ago that only the wealthy can "luxury" one of the consumer. So, for the first time, the person selected home projector, or ready to upgrade older machines to consumers this year, home projectors buy what it needs attention?
Technical Stream selected chip Since it is a home theater, it certainly is a core part of the visual part, because the theater may not sound initially, but can not not image. Through vision, we are able to perceive external objects, the size, brightness, color, movement, access to the survival of the organism is important in all kinds of information, more than 80% of our information through visual access to the outside world, so the visual as the core of our position on build home theater foundation.
At present, home projectors, and the main types of graphics chips, including three type L CD Technology products, the three chip LCOS technology, and chip-based DLP projector products. DLP projector, with its lightweight portable, accurate and true image restore, image layering is good, excellent black effect (LCD's black is also not hide how dusty feel), and so are at the stage of rapid development, while the LCD projector The technology is relatively mature, with gorgeous colors, saturation and good technical advantages. 3LCOS the above two advantages of both.
While 3LCOS technology projector, seem to have a combination of LCD technology and the advantages of DLP technology, and significantly improved both the lack of features. LCOS projectors but also has inherent disadvantage. That is the perfect solution has not been chip yield problems. This makes the LCOS product can maximize their strengths, to maintain the profits of the end product, so that their products are not too cheap.
For consumers, choose cheap home projector million 3LCD single-chip DLP technology and products is the best choice. This type of product has good overall performance and higher cost. In the high-end products, LCOS technology types of projectors are widely loved. Single-chip DLP projector is the top product in the high-performance LCOS technology products and some a try. Comparison, high-end products camp, 3LCD technology products most are not optimistic. In the luxury class market products are absolutely 3DLP world, all impeccable performance, but hundreds of thousands or even millions of ordinary consumers, the prices are unacceptable.
For the same type of technology, the same resolution, the display chip, chip, consumers also need to pay attention to their "generation." With generation-related factors include "open rate" "Leaky situation", and "cost." Typically, the high aperture ratio higher generation products, Leaky less, but prices are also higher. High aperture ratio and low-light leakage rate can bring higher contrast and smoother picture effect.
Resolution can not be ignored, quantity "force" and select
Home theater projector has a physical resolution of targets, it is the core component of the resolution by the decision of projection, resolution may largely determine the degree of image clarity and precision, the projector also determine the most appropriate Show image type, the higher the resolution the projector displayed the image the more delicate smooth. Generally, the price of the projector with the resolution of a great relationship, the higher the resolution of the retail price of projectors are also higher, while the price is relatively low resolution would be cheaper. So, choose which level of resolution of the projector, then the amount consumers need to "force" but chose, here called "power" refers to economic empowerment.
People to buy home theater projector, the resolution is a critical factor. Many consumers mistakenly believe "that is representative of high-quality high-resolution screen." In fact, at present most of the 480p resolution projector and the screen-resolution signal processing aspects of high-definition performance is excellent, with good graphics. If you only watch the standard DVD or ordinary TV Signal, then the 854x480 resolution of the projector can achieve line to line, no zoom, the maximum on the faithful reproduction of the picture effect of information sources.
