The fact that 4K is mentioned is not a new topic anymore. Whether it is LCD TVs or monitors that you want to sell well, it seems that you have to bring 4K words. But for projectors, whether it is a high-definition home projector or a fiery smart microprojector, it seems that 4K sounds are rarely heard. Why is this? Is there any practical significance for the 4K resolution? Today we came to chat about 4K in the display area.
4K points useless? Why projection can't afford super high resolution
The 4K resolution is known as the standard resolution of a new generation of Hollywood blockbusters, with 4096×2160. It is 4 times the traditional 1080P resolution, and the number of pixels has been raised from 2 million to 8 million. Theoretically, it can give viewers clearer, more realistic and detailed display details. However, if you actually watch 4K movies, you actually find that the actual results are not as beautiful as they are. Because the distance in the theater makes the 4K movie not much different from the ordinary 2K movie, if there is no one to suggest, you are likely to think this is an ordinary movie.
Whether it is a large-size LCD TV, a monitor or even a projector, it is actually a display device. But on the one hand, the 2K, 4K, and 5K monitors are changing their designs, while the mainstream resolution of the other side of the projector has always been 1920×1080. Is there a 4K projector? No, Sony's VW1100ES, VW500ES, VW300ES, HW40ES and other models are all 4K projectors, which are rare products in the industry. So why does the projector not promote and popularize 4K resolution like the monitor and LCD TV?
First of all, the product positioning of high-definition home projectors and smart pico projectors is different from that of LCD TVs and monitors. We mainly buy high-definition projectors and smart micro projectors. They are mainly used to watch movies at home, because after all, projectors can easily project one or two hundred The big picture of the inch, if possible, is that if you want to build a private cinema at home, there is no problem. Watching movies first involves film source issues. The mainstream movies and videos are also in 1080P format. For projectors, there is no sufficient reason to rashly promote 4K products. So why are 4K sources so scarce?
This article mainly explains from the following dimensions
Is the existence of 1,4K currently meaningful?
2,4K actual viewing effect is not so beautiful
3, not blind, why the projector does not push 4K
4, 4K projection of the future still have to see the mainstream source
Is the existence of 4K currently meaningful?
In fact, whether it is a 4K monitor or a 4K TV and our leading 4K projector, we are faced with a problem and it is hard to find a 4K source. This 4K display device is quite embarrassing situation, a bit of hero meaningless. Many friends may ask why movie companies don’t shoot some 4K movies. The reason is simple, one word, expensive!
The film is actually an industry. The final product is the film presented to us. However, before that, several procedures were required, including pre-production, post-production, approval, distribution, theater screening, etc. For 4K movies, whether it is the pre-shooting, film storage, post-production, or theater playback, a special 4K device is required. Currently, manufacturers that can produce 4K projector technology include Barco, NEC, Christie and Sony using LCoS technology using TI's 3DLP chips.
The monopoly of upstream projection technology has led to a very expensive shooting of a 4K film. It is very normal for a single 4K film to display more than one million mobiles, which directly affects the number of 4K screens worldwide. According to the statistics, the 4K screen around the world The number is about 2,000 or so. The high costs make it impossible for the cinemas to purchase 4K film projection equipment, and the number of original film sources is scarce, and there is no need to spend heavily on upgrade projection equipment. So apart from the costly reasons, what factors restrict the development of 4K videos?
4K actual viewing effect is not so beautiful
In fact, in addition to the cost, the experience of 4K movies is also a major constraint. In order to experience the 4K high-definition effect, a large screen and a proper distance are indispensable. The 4K picture above 60 inches must ensure that the 4K picture quality can be felt within a distance of 1 meter. This looks like a big challenge to our eyes.
For the cinema, I myself had been invited to watch a domestically produced 4K movie before. I didn't mention the specific name. To tell the truth, there is no obvious difference between the actual experience and the ordinary 2K. Even if it is a giant screen in a movie theater, it is impossible for the audience to experience the vividness and exquisiteness of the propaganda because of distance.
In addition, for our daily home movies, a storage space of about 5T for 4K movies in less than two hours is a pit for our current mainstream storage devices. In addition, as far as the transmission of 4K movies is concerned, the bandwidth requirement can be imagined. Although domestic broadband has been accelerated many times, Alexandria still faces 4K video transmission. In terms of current storage media and bandwidth speeds, it is indeed difficult to promote 4K.
Not blind, why does the projector not push 4K?
In addition to the bottleneck mentioned above in the 4K movie itself, why is there not a large-scale popularization and promotion of 4K products like LCD monitors and TVs for projectors?
From a technical point of view, most of today's high-definition home projectors use DLP technology, which is based primarily on digital micromirror DMD chips developed by Texas Instruments. The price of a 4K DMD chip is in the range of hundreds of thousands, which is too expensive for a projector manufacturer. Therefore, even if a 4K projector is introduced, few users purchase it. Therefore, 4K projectors cannot be marketed as flagship products.
The current 4K gimmicks are larger, but the actual lack of support from the film sources makes it easier to publicize but the actual experience is inevitable. However, for the user community of high-definition home projectors or smart pico projectors, the original intention of buying is still to experience the pleasure of small-scale theaters at home. Therefore, the current high-definition projectors are more focused on improving the brightness and the accuracy of color reproduction through the innovation of light sources such as lasers and six-segment color wheels. In terms of content, the built-in intelligent system is used to enhance the richness of video resources to meet the actual needs of users actually watching videos.
The future of 4K projection still depends on the mainstream source
Having said so much about 4K, or returning to the theme of the article, can 4K projectors become popular in the future? Of course, as a display device, the popularity of 4K projectors is constrained by the cost of 4K DMD chips on the one hand. Currently, the price of DMD chips at the core of 4K projectors is indeed more expensive. In a short time, the projector manufacturers do not need to be large-scale. To promote 4K projection products, for home users, the projector manufacturers more focus on entry-level 1080P HD projection and smart projection, because they can meet the needs of users watching movies.
In addition to technical reasons, on the other hand, the more important one is the popularization of 4K sources. Like the current mainstream 1920×1080 resolution movie, 1080P movies are widely used, making hardware playback devices also necessary. Therefore, the projector and the 4K source can be said to have a concomitant relationship. Otherwise, there is no 4K source, even if the popularity of 4K HD projection does not seem too practical.
Summary: This article reads more about the problems faced by 4K movies, including the high cost of shooting, screening, and poor actual viewing. It analyzes why the projector industry is not as popular as other display devices such as LCD TVs and monitors. equipment. In addition to the core technical cost reasons, I would probably have to wait until the day when the 4K source becomes mainstream.
