The data shows that in 2017, shipments of TVs above 60 inches increased significantly, and the trend of large-screen display in home display market became more and more obvious. With the improvement of living standards, more and more people are pursuing the immersive experience brought by the big screen. Next, the author will analyze several household screens for everyone. I believe they will appear very frequently in the future. 
In addition, after the LCD TV reaches 100 miles, it is very inconvenient to install or handle, and it may even be difficult to enter the living room from the ordinary door. Before the news reported that because 100-inch LCD TV is too large, the user can only helplessly. Choose to lift it from the window by lifting it. Since laser televisions do not have physical screens, they do not have to worry about these problems.
The road to 8K popularity is long way to go. With the increase of screens, the user's demand for resolution will inevitably increase. The current 4K resolution has become the mainstream of the high-end large-screen market. But in the eyes of discerning users, 4K is by no means the end, and 8K is the goal that everybody pursues.
In addition to the increased sharpness, 8K color performance has also been greatly improved. The HDTV is now using the BT.709 color standard. It cannot show all the colors in nature. The 8K product adopts the BT.2020 standard, so the range of color gamut is greatly improved, and even colors that do not exist in nature can be presented.
8K content shooting and production is also a big problem, even the most powerful SLR, but also barely able to achieve shooting, but can not guarantee the quality of the video. In addition, 8K video has a very high demand for video components such as video processors. At present, most image processing devices cannot complete 8K video processing and production.
HDR makes the picture more appealing. HDR is the high dynamic range. The dynamic range is a technical term that describes the range of brightness levels of a given scene in a mathematical way. Simply means the brightest point and the darkest point in an image. The ratio between the places. So HDR technology is to make brighter areas of the image brighter, and darker areas are darker.
I have personally reviewed the laser TV with HDR function. From the figure below, we can see that the left is the screen performance after the HDR function is turned on, and the right is the effect that the HDR function is not turned on. It can be seen from the figure that after the HDR function is turned on, the contrast of the picture is stronger, the highlight details are more prominent, and the darkness performance is even darker, and the picture is more contagious.
In essence, HDR is actually a substantial extension of the overall contrast range of the picture, which is not only limited to white, but also involves other colors. In the future of the home screen industry, HDR technology will certainly become a standard feature. In order to obtain a good HDR picture, the most critical point is the brightness output and color performance. The wider the color gamut and the higher the brightness, the full potential of HDR high dynamic picture can be fully released.
The most economical big-screen choice for smart micro-projection The reason why the author put smart micro-projection here is because smart micro-projection is currently the lowest cost home large-screen device. Compared with the high price of laser television, such a price can be completely accepted by most users.
Editor's opinion: The upgrade of home display devices is the future development trend. From laser television to smart micro-projection, whether local tyrants or dwellings can enjoy a big screen at home. However, the increase in size must be accompanied by technological advancement. If it is only a simple increase in size that does not increase the image quality, I believe that this is of little significance to the development of the entire industry. Therefore, how to present a more outstanding picture in a larger size is an urgent problem for major manufacturers in the future.

Laser/8K/HDR Resolution Large Screen Market Technology
Laser TV Big Screen Market First Choice The basis of laser television is projection technology, but the light source used is changed from light bulb to laser light. Everyone knows that lasers have the advantages of stable light emitting performance and long service life. In this way, it is a good solution to the traditional projector brightness, color cast and other issues. In addition, the emergence of ultra-short-focus technology is to make the projection distance is almost close to zero, so laser television technology can fully meet the needs of users. The essence of laser television is projection technology
In the large screen area of ​​70 inches or more, laser television has a great advantage. The first is the cost. The cost of LCD TVs will increase rapidly with the increase in size. The price of 100-inch LCD TVs will be as high as several hundred thousand yuan. This price is not affordable for ordinary home users. In contrast, the price of entry-level laser televisions has now fallen below ten thousand yuan (excluding light curtains), so in the big-screen market, laser televisions have a cost advantage over traditional LCD TVs. In addition, after the LCD TV reaches 100 miles, it is very inconvenient to install or handle, and it may even be difficult to enter the living room from the ordinary door. Before the news reported that because 100-inch LCD TV is too large, the user can only helplessly. Choose to lift it from the window by lifting it. Since laser televisions do not have physical screens, they do not have to worry about these problems.
As there is no physical screen, laser televisions are more convenient for transportation and removal.
There are some problems with laser televisions. The first is the brightness. Entry-level laser televisions cannot be watched at noon even when they are equipped with anti-light curtains. Secondly, the color performance of monochromatic lasers is also slightly defective, in which the red and green parts are generated by the color wheel, so the color performance has yet to be improved. However, the current cost of two-color laser is too high, and the price of 7,800,000 is still unacceptable to most users. Future brightness and color are the direction in which laser televisions need to improve. The road to 8K popularity is long way to go. With the increase of screens, the user's demand for resolution will inevitably increase. The current 4K resolution has become the mainstream of the high-end large-screen market. But in the eyes of discerning users, 4K is by no means the end, and 8K is the goal that everybody pursues.
8K TV
The 8K resolution was promoted by the Japan Broadcasting Association, the BBC, and the Italian Radio and Television Corporation. 8K has a resolution of 7680x4320, ie 7680 effective pixels in the horizontal direction and 4320 effective pixels in the vertical direction, approximately 33 million pixels in each frame. Its resolution is 4 times that of 4K and 16 times that of 1080P. In addition to the increased sharpness, 8K color performance has also been greatly improved. The HDTV is now using the BT.709 color standard. It cannot show all the colors in nature. The 8K product adopts the BT.2020 standard, so the range of color gamut is greatly improved, and even colors that do not exist in nature can be presented.
8K resolution is clear and sharp even on the large screen
At present, 8K TV has entered the market, but the biggest problem facing 8K is that there are too few video sources. Although the Rio Olympic Games in 2016 has already achieved 8K satellite signal pilots, and Japan will soon open 8K video broadcasts, but these are not enough, so I think the current 8K is only the concept of vendor speculation. 8K content shooting and production is also a big problem, even the most powerful SLR, but also barely able to achieve shooting, but can not guarantee the quality of the video. In addition, 8K video has a very high demand for video components such as video processors. At present, most image processing devices cannot complete 8K video processing and production.
8K vs. 4K and 1080P
The end product and content are interdependent, but in the 8K aspect, the end product has been implemented, but the content part has a long way to go. At present, domestic 4K is just in the bud, even if the number of 4K content sources is not enough, let alone 8K. So the distance between 8K and general home users is still far away. But in the future, I believe 8K will become the most frequently used term in the big screen market. HDR makes the picture more appealing. HDR is the high dynamic range. The dynamic range is a technical term that describes the range of brightness levels of a given scene in a mathematical way. Simply means the brightest point and the darkest point in an image. The ratio between the places. So HDR technology is to make brighter areas of the image brighter, and darker areas are darker.
Application of HDR Technology
The range of brightness that can be felt by the human eye is approximately 10-3 to 106 nit, and the instantaneous contrast range that can be felt can reach 10,000:1. However, the brightness of current consumer-grade liquid crystal displays is generally around 300 to 400 nit, and the contrast range is generally 2000. :1. Therefore, the eye's brightness resolution capability is much higher than the current mainstream display devices. The HDR display technology is to increase the contrast range of the display, so that we can see the image better. I have personally reviewed the laser TV with HDR function. From the figure below, we can see that the left is the screen performance after the HDR function is turned on, and the right is the effect that the HDR function is not turned on. It can be seen from the figure that after the HDR function is turned on, the contrast of the picture is stronger, the highlight details are more prominent, and the darkness performance is even darker, and the picture is more contagious.

In essence, HDR is actually a substantial extension of the overall contrast range of the picture, which is not only limited to white, but also involves other colors. In the future of the home screen industry, HDR technology will certainly become a standard feature. In order to obtain a good HDR picture, the most critical point is the brightness output and color performance. The wider the color gamut and the higher the brightness, the full potential of HDR high dynamic picture can be fully released.
The most economical big-screen choice for smart micro-projection The reason why the author put smart micro-projection here is because smart micro-projection is currently the lowest cost home large-screen device. Compared with the high price of laser television, such a price can be completely accepted by most users.
For users with low budget, smart micro investment is a good choice for home viewing
As a very popular product recently, smart micro-investment is highly sought after by young people. Its compact size makes it ideal for carrying, and even some micro-projectors are similar in size to a cell phone, so users can easily put it in their hand bag. In addition, compared with laser televisions and traditional home projectors, the price of smart micro-projections is also cheaper. At present, the price of 1080P smart micro-investment is less than 3,000 yuan. The price of WXGA products is even lower. Brightness is the weak point of intelligent micro-investment
However, due to the limitation of the body size, the brightness of the micro-projection has been underperforming, and the use effect is not satisfactory in a bright environment. The user can only get better viewing in a relatively dark state. Experience. Looking into the future, I believe that there will be more and more budget-deficient friends choose smart micro-projection as the main force of the home screen. Editor's opinion: The upgrade of home display devices is the future development trend. From laser television to smart micro-projection, whether local tyrants or dwellings can enjoy a big screen at home. However, the increase in size must be accompanied by technological advancement. If it is only a simple increase in size that does not increase the image quality, I believe that this is of little significance to the development of the entire industry. Therefore, how to present a more outstanding picture in a larger size is an urgent problem for major manufacturers in the future.
