Many people are familiar with projectors in classrooms and conference rooms. In fact, education and business are the biggest markets for projectors. The projector industry has always been trying to enter the home sector, but the home market has not been able to occupy a large share in the projector field. In the past, projectors were expensive and could not be accepted by home users. Therefore, projectors would need to face price problems when they wanted to popularize homes. So is it right? The problem of price is solved, can really let the projector become the new choice of family user? Today we will analyze this issue.
PK TV grab the living room home projection pie why not open?
Today, the equipment used to occupy the living room is mainly LCD TVs. Recently, LeTV launched a nearly 500,000 yuan LCD TV, the size is indeed large enough, but the price is also staggering. However, in fact, the price of popular LCD TVs is now very favorable. Under the impact of internet companies in recent years, the price of LCD TVs has been falling particularly fast. Today, a 55-inch LCD TV often sells only 3,500 yuan on the Internet, and it still has an intelligent system. In particular, we can see how much the price of TV is discounted.
Home projectors have not been universal
3500 yuan price for the projector market, what kind of products can be purchased? Professional highlight projectors don't want to think about it. Such a price can generally buy a XGA (1024×768) resolution business or education projector. Their brightness is generally between 3,000 and 4,000 lumens. This configuration is an entry-level level in the field of projectors. From the comparison we can see that the price of the projector is still more expensive.
The price of 1080P home projector slides quickly
However, after all, the projector can achieve a larger size, and it is worth mentioning that the price of home projectors has been also reduced, the price of home projectors in the past 1080P is generally more than 10,000 yuan, through the development of the two years, in The price of around 5,000 yuan is also a home projector with 1080P resolution. In this kind of product, casting a 120-inch screen in the right environment is still a little stressful. However, such home projectors are also sold flat, I believe that even if prices continue to decline, the user's stimulus is not great.
In fact, in addition to the price issue, the projector needs a lot of space, which is also a very problematic headache. We know that with the continuous rise in housing prices, many families have chosen to purchase Xiaoping’s homes. Using a projector in such a room naturally has a lot of inconvenience. In general, if a projector is to achieve a large size, at least a distance of three or four meters is required. For Xiao Xiaoping, this is a bit extravagant.
Traditional lifting requires many modifications
And if the projector is used for hoisting, early planning is also required. If it is a newly-renovated home, the user can plan well before the installation and it is not particularly troublesome to install it. However, if it is a late home improvement, it is necessary to consider many issues. Problems such as alignment, power consumption, aesthetic issues, etc., make many people prohibitive.
Reflective ultra-short throw projector can save a lot of space
In order to solve these problems, there are new solutions in the industry. That is the appearance of ultra-short focal reflection projectors, which can solve the projector's distance problem. Place the projector on the desk or hang it on top of the screen to achieve a large screen shot. The reason why this effect can be achieved is that the projector lens adopts short focus, and the principle of reflection is used to greatly shorten the distance. However, the disadvantage of this is that the projection screen is prone to distortion. The so-called "projection TV" is actually such a product. However, this product has not yet become mainstream.
To solve the problem of distance, in fact, the projector brightness problem is also a big challenge, we know that the projector is very sensitive to brightness. For the average user's home, the darkroom is not very existent, and it is very expensive to create a special dark room, and such a dark room has a single function, and can only be used to view the projector. Then only local tyrants can do this. . There are indeed many people who have built garage theaters and spent more than 100,000 yuan to upgrade. However, this is not something that the average person can afford.
Laser Projector System
The mainstream light source of projectors is still ultra-high-pressure halogen lamps. This kind of light not only generates heat, is fragile, but also consumes a lot of energy. Therefore, the sound of the light source has been eliminated. However, there is no way that other light source technologies are still not very mature. For example, lasers are really very powerful. In the commercial sector, they can even achieve more than 30,000 lumens, but their own size is really too large.
High brightness requires laser array
To achieve such a high brightness, an array of lasers is needed to support it. The size of this laser array is too large, almost the same size as double-door refrigerators, and its energy consumption is ridiculously high, so ordinary homes cannot currently use such arrays. Of course, there are projectors with pure lasers, but their brightness is similar to that of traditional high-pressure lamps, so there is no way to really solve the problem of brightness.
