Death TV LCD TV analyzes the evolution of home projection

The initial advantage of home projectors is that the size is large enough. When 50-inch LCD TVs are still rare, home projectors can easily achieve large screen sizes of 100 inches or even 120 inches. This is why many people buy the core of home projectors. element. But this size can't be upgraded too much, because continuing to upgrade to 150 inches is already too big, as for 200 inches of large screens, the average family does not have such space at all, so although the projector has the advantage of the size, but in the size There is not much room for improvement, so we can only upgrade in other areas.

Home projector has not been widely used

The resolution advantage is not obvious

Ultra-short focus is the application requirements

So how can we promote the progress of home projectors? We all know that projector projection requires distance. In the past, this distance was about three or four meters, so as to project 100-inch images. But many people do not have such space in their homes, so our short-term demand has always existed. Short shots can project larger sizes at shorter distances.

Reflective ultra-short focus in education market

As a result, short-throw projectors have emerged. The first short-focus projectors are products of fisheye lenses. Such products can shorten certain distances, but they still cannot truly solve the needs of users. At this time, the reflection-type ultra-short-focus projector appeared. Using the principle of reflection, home projectors can now achieve a projection of a 100-inch screen at a distance of 40 cm. Laser TVs use such technology.

Intelligent system solves content problems

With an ultra-short focus and a large short-range picture, what is missing from home projectors? Now that there is a system for smart LCD TVs, it is clear that home projectors need to keep up with this trend. Now that there are many projectors with intelligent systems, they can achieve the effects of watching movies online and watching TV shows. In addition, the smart system also supports the screen-casting function, so that by using technologies such as DLNA, the contents of the mobile phone screen can be projected onto the large screen of the projection. The system solves the problem of what the projector sees. People no longer need a separate output device.

Home projectors also join smart systems

The laser light source fills the obvious short board

After solving these problems, the brightness of the projector and the life of the light source become the most obvious shortcomings. Fortunately, laser light sources have also emerged. Laser light sources can not only achieve high brightness compared to traditional light bulbs, but also can provide up to 20,000 hours of life, so even if it is an 8-hour application, don't worry about always changing. Light bulbs. However, the current price of laser light sources is still relatively expensive, which is why laser televisions are at an important level of 20,000 yuan.

Laser TV is a masterpiece of home projector evolution

Home projectors have been evolving from screen size to resolution to systems and light sources. Almost all avant-garde technologies now appear on laser television products. This reflective ultra-short-poke laser light source home smart projector is a collection of Although the projector’s evolutionary power for nearly three decades cannot completely replace LCD TVs, I believe that this kind of product will continue to progress, and when the price is reasonable, it can still become a new landscape in people’s living rooms.
