How far is the 8K projection from us? Many problems need to be solved
At this year's InfoComm show will be a new 8K laser projector debut, this product uses a solid-state laser light source, the brightness reaches more than 20,000 lumens. In fact, this is not the first show of the 8K projection, as early as the end of last year, 8K projection has already entered the public view.
Although frequently appearing at the show, I believe that 8K projection is still far away from ordinary users' lives. Because at the end of last year, 4K only ushered in the popularity of the home projection field. Now whether it is a product or supporting technology, 8K projection has a long way to go in the home field.
Technology is immature
The first problem with 8K projection 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 3LCDs belongs to 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 support from upstream manufacturers. It is obviously unrealistic to implement mass production of 8K projections.
In other words, once 8K chips are available, 8K projectors can quickly become popular? The answer is also negative. The projector itself is a sophisticated device and the light path system inside the fuselage 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 traditional 1080P and 4K products, 8K projectors generate more heat at work, and 8K resolution requires more light path space, which requires more space inside the projector, so the 8K projector The volume also becomes very large. As you can see, the projection products that have achieved 8K resolution now are very large, almost the size of bedroom cabinets.
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. In today's technology is not yet mature, even if such an 8K home projection product is launched, it will not bring a good user experience.
In addition to the content source
In addition to these basic issues of chip and volume, the supporting technology of 8K projection is not yet perfect. The author believes that this is actually similar to the development of 4K. In 4K in 2011, it has received a lot of attention, but until today, the 4K system has not yet been fully constructed, and the number of 4K sources is still not satisfactory.
What 8K faces first is the content source problem. Although the Rio Olympic Games in 2016 has already achieved the piloting of 8K satellite signals, Japan will also open an 8K live video broadcast soon, but these are not enough. The 8K picture is very demanding for the device, and the dedicated 8K camera is expensive. At present, the most powerful SLR is only barely able to achieve shooting, so there are few 8K content sources until now.
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. In other words, existing storage devices and network transmission devices need to be upgraded with 8K. Today, 8K devices have not yet been popularized and no one is willing to bear this huge expenditure.
From the lack of content sources to the imperfect supporting technologies, these have severely limited the development of 8K projections. In other words, even if you currently own 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 the end of last year 4K home projector has just opened the road to popularity, this year should be the focus of the 4K projection layout of the home area, as 8K is still too early to say.
But looking to the future, 8K must be the development direction of the projection industry, because compared with other home display devices, the large screen of the projection has higher resolution requirements. In addition, issues such as playback, decoding, and source are not to worry too much, because once the 8K equipment is widely used, related industries will also develop rapidly. By then, these problems can be solved very well.
In addition, people are delighted that China's Internet communication technology is developing rapidly, which will lay the foundation for the transmission of 8K content. Shortly afterwards, 5G high-speed network may come to our side, which will become an important support for 8K display devices. Therefore, we have reason to believe that in the future, the 8K in the home screen field will become the protagonist sooner or later.
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 cut, 4K projection took six years. We are currently at the point of time when 8K has just come out, which means that we still need 5 to 6 years to get the popularity of 8K projection.
8K has become the vocabulary with the highest percentage of household display areas 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, neither chips nor supporting technologies are 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, we may enjoy the ultimate viewing experience brought by 8K at home in a few years.
