At this year's InfoComm show will be a new 8K laser projector debut, this product uses a solid-state laser light source, brightness of 20,000 lumens or more. In fact, this is not the first show of 8K projection, as early as the end of last year 8K projection has already entered The public's vision.
Although frequently appearing at the show, I believe that the 8K projection is still far away from the average user's life. Because at the end of last year, 4K ushered in the popularization stage in the home projection field. Now whether it is a product or supporting technology, 8K projection in the home area There is still a long way to go.
How far is it to debut the InfoComm 8K projection?
Technology is immature
The first problem faced by 8K projectors is the chip. Currently, the mainstream projection products on the market are divided into two camps: DLP and 3LCD. The core technology of DLP projectors is in the hands of the Texas Instruments factory in the United States, and the core technology of 3LCD is Epson.
Until today, Texas Instruments has not introduced 8K chips, and Epson has not introduced 8K 3LCD technology products. Currently, 8K projection products appearing in the market are mostly implemented with 8K resolution through frame interpolation technology, if there is no upstream vendor support. , 8K projection to achieve large-scale mass production is clearly unrealistic.
The light path inside the projector is very complicated
That is, once an 8K chip is available, the 8K projector can quickly become popular. The answer is also negative. The projector itself is a sophisticated device. The optical system inside the camera body is very complicated. In addition to transforming DMD chips and LCD panels, Other light path systems have to be redesigned. This series of improvements is not simple.
In addition, compared to the traditional 1080P and 4K products, the 8K projector generates more heat at work, and the 8K resolution requires more light path space, which requires a larger space inside the projector, so the 8K projector The volume has also become very large. As you can see, the 8K resolution projection product is now very large, almost the size of a bedroom cabinet.
The size of the 8K projector is similar to that of a large-scale project. It is very large.
There is absolutely no room for a typical home user to accommodate such a large body. Therefore, after such a model is put into the home projection market, whether it is an ordinary table casting method or a lifting method, it is not so practical. Immature today, even if such an 8K home projection product is introduced, it will not bring a good user experience.
In addition to the content source
In addition to the basic issues of chip and volume, the supporting technology of 8K projection is not yet perfect. The author thinks that this is actually similar to the development of 4K. In 2011, 4K has received a lot of attention, but until today, the 4K system has not been built yet. Completely, the number of 4K sources is not yet satisfactory.
The first thing 8K faces is content source issues. Although the Rio Olympic Games in 2016 has already achieved a pilot of 8K satellite signals, Japan will also open an 8K video broadcast shortly thereafter, but these are far from enough. And 8K screens for devices Very demanding, dedicated 8K cameras are expensive. At present, the most powerful SLR is only barely able to achieve shooting, so until now 8K content sources are also few.
8K camera
In addition, the production of 8K content is also a big problem. 8K video has a very high demand for video components such as image processors. At present, most image processing devices cannot complete 8K video processing and production. That is, existing storage devices. And network transmission equipment needs to be upgraded with 8K. Today, 8K equipment is not widely used. No one wants to bear this huge expenditure.
Existing devices need to be upgraded with 8K
From the lack of content sources to the imperfections of supporting technologies, these have severely limited the development of 8K projection. In other words, even if you now have 8K display devices, you may not be able to use them.
Editorial point 8K is not now but the future
The author believes that it is still too early to discuss the 8K projection. To know that 4K home projectors have only recently opened up the road to the end of last year, this year should be the year that 4K projection focuses on the layout of the home field. As for 8K, it is still too early to say.
The large-screen projection screen requires more resolution, but looking ahead, the 8K must be the development direction of the projection industry. Compared with other home display devices, the large screen of the projection has higher resolution requirements. We do not have to worry too much about issues such as playback, decoding, and source, because once the 8K devices are widely used, the related industries will also develop rapidly. By then, these problems can be solved very well.
In addition, people are delighted that China’s Internet communications technology is developing rapidly, which will lay the foundation for the transmission of 8K content. Shortly afterwards, 5G high-speed networks may come to us, which will become an important support for 8K display devices. Therefore, we have reason to believe that the future will sooner or later become the protagonist of 8K in the home screen area.
5G network will become an important support for 8K
The appearance and elimination of products need to follow certain rules, so the author predicts that 8K may develop along the 4K footprint in the projection field. From the 2011 proposal to the 2017 price reduction, 4K projection took six years. Currently we It is just at the time of 8K, which means that we still need 5 to 6 years to get the popularity of 8K projection.
8K has become the most frequently used term in the home display industry in recent years. 8K projectors frequently appear in major exhibitions, and 8K TVs have already entered the user's field of vision. However, in the current projection field, whether it is chips or supporting technologies. They are not mature enough. Therefore, it is still too early to talk about 8K penetration. However, in the future, 8K must be the development direction of the projection industry. With the advancement of technology, perhaps in the next few years we will be able to enjoy the ultimate 8K experience at home. Experience.
