With the general improvement of people's living standards and the greatly improved living environment, the requirements for family film and television products are becoming higher and higher. Large screens, high definition, true colors, and immersive shock effects have become the pursuit goals of many families. . At present, following rear projection and plasma TVs, projectors have gradually entered ordinary households.
Although different display projection devices have their own characteristics, compared with high-end TV products, the projector has its own unique advantages, that is, the picture is large, the brightness is good, it is compatible with multiple video signals, and the size is not limited, and the weight is light . At present, although the main application scope of the projector is still limited to the commercial field and the education industry; but the projector can bring shock to the large screen of the family by virtue of the above many unique advantages. Not only enjoy movies at home, you can also use the projector to connect with personal computers, video recorders, DVD players and digital TVs, and now play karaoke or music images, receive images from remote courses and community centers. When the projector and audio are combined into a multimedia home theater, the audiovisual effect is no different from a real theater. Think about it, the first thing that catches your eyes is the huge screen in front of you, there is a huge body of dinosaurs, the huge waves are almost going to devour everything, and the sword is also straight out, making people immersed in the real environment of the film To feel the shocking cinematic effect.
It is precisely because of the advantages of home projectors that its share in the home market is also increasing. To comply with the market demand trends, Toshiba, NEC, Sharp and other international brands have launched home projectors, and domestic projector brands Morningstar There have also been respective product launches. Ordinary families often lack a certain understanding of projectors, which is extremely easy to cause investment waste and even decision-making mistakes when purchasing. So, how to buy a home projector with reasonable price and suitable function?
Ceiling and display: follow your preferences Before users choose to purchase a projector, they should be familiar with how to use the projector. There are generally two ways to place the projector, for ceiling installation or on the coffee table when needed. If you need fixed installation and use, you can choose the ceiling method. It is best to carry out the decoration at the same time. This can hide all the lines, which is not only beautiful, but also saves space, but you must pay attention to dust and heat dissipation. Two unique projectors are recommended here. Once many projectors are installed, readjusting the projection position takes time and effort. When replacing the lamp, NEC VT47 + only needs to remove some screws of the hanging fixture (VT70CM), without removing the entire projector from the ceiling, saving time and effort. The movement adopted by Sharp XR-N10S is a completely sealed structure, so it is better than ordinary projectors in dust resistance, longer service life, and greatly reduces the user's subsequent use costs.
The advantage of the display is that the projector can be moved and used like a laptop. Due to the limitation of positioning, the projected image may become trapezoidal. Therefore, it is best to purchase a projector with trapezoidal correction function. For example, Toshiba TDP-S25 with automatic keystone correction function greatly facilitates the user's application.
Performance index: the best for selection The first choice of a projector depends on its brightness index. This is the prerequisite basis for enjoying a big picture. Generally speaking, the larger the picture, the higher the brightness. But it's not that the higher the brightness, the better, because the screen size of different units is limited, and the brightness does not need to be high to get a good projection effect.
Contrast and brightness are a factor considered in association. Contrast is the ratio of the brightest and darkest areas of the picture, and its impact on visual effects is second only to the brightness index. Generally speaking, the greater the contrast, the clearer the image and the better the sense of layering. Especially for movies, dark techniques are used, and high contrast This is especially important in home theater products. For example, the contrast ratio of Toshiba S25 is as high as 2000: 1, which is enough to meet the needs of setting up a home theater.
The projector is the same as the digital camera and digital video camera, and its image quality is based on the resolution. The higher the resolution, the smoother and smoother the image displayed by the projector is divided into XGA level, which is 1024 × 768; SVGA level, which is 800 × 600; SXGA level, which is 1280 × 1024. The first two are more common on the market. It should be noted that the higher the resolution, the more expensive the price. Toshiba S25, NEC VT47 + and Sharp XR-N10S all have SVGA resolution. Generally speaking, the effect of SVGA can already meet the needs of families.
For the projector, the bulb is its main consumable, and its life is directly related to the cost of using the projector, so be sure to ask the lamp life and replacement cost when purchasing. In addition, we must pay attention to the after-sales service of the product. After all, the price of the projector is tens of thousands of high-precision products. Only with good service can we give users a "heart-rest".
The Toshiba mentioned above is an example. It relies on Digital China as a sales agent for super products in China and has a service brand image of "five-star" service. The terms of service include the first year and the second year are the whole machine warranty, The third year is the warranty of the whole machine except the "optical machine" and "power supply", the projector lamp enjoys 99 days of quality assurance, and promises to repair parts beyond the warranty period for free repair of parts cost fees; free dust removal service; 24-hour telephone Response; the maintenance service network all over the country can provide nearby services and provide users with meticulous and perfect services. Therefore, you should choose to buy a projector of a well-known brand, so that you can enjoy the after-sales service of the merchant, so as to avoid the worries of using the projector.
