Eye-raising living room giant screen measuring Hisense 4K laser TV

To discuss who is the most cutting-edge display technology, I think this should be talked about from the shooting technology, whether television or professional-level monitor products, the purpose is to most accurately restore the director's shooting intentions and the later color style.
Which industry can use the most advanced shooting technology? Taking Avatar, the most important advancement of 3D technology a few years ago, to see it, the answer is definitely the film industry. It is more eager for the emergence and trial of new technologies than broadcast systems.
Billing Lynn, the world’s top film shooting technology, recently selected a laser system for screening. A film with the same landmark as Avatar’s was released. It was a time when more than 200 tickets were sold and only two theaters in the Mainland could play the highest version. Li Lynn's midfield battle. The film subverted the frame rate limit that had previously been used as a technical standard for the film industry for 24 frames, and directly increased the number of frames to 120 frames, which was five times the current technical standard.

Billy Lynn's midfield battle of 120 frames is just a technological breakthrough. It combines 120 frames with 4K and 3D technologies. Because 120 frames are 5 times that of 24 frames, 4K is 4 times that of 1080P, and 3D is 2 times that of 2D, it is already very difficult to decode and play Bill Lillen's uncompressed original film, let alone this kind of " "Advanced" shooting technology is restored and displayed on current display devices.
Laser display with high brightness and wide color gamut

Billy Lynn's display requirements are extremely demanding. It requires the cinema to display a brightness of 28FL (foot-lambert), and the brightness of the 3D movies played in the theaters we frequent is only 2.5 to 4.5FL. Therefore, the mainland can see that the highest version of Billy Lynn's two theaters are using a certain brand of Mirage 4KLH RGB top laser projection system, this system can reach up to 120,000 lumens, only the current laser display technology can be completed.
For the laser projection equipment, its technical advantage is not only far beyond the brightness output capabilities of other projection equipment. In fact, the laser display is also quite powerful in terms of color reproduction.
We all know that the flat panel TV's color display is achieved by white backlight plus RGB filter to achieve the three primary colors of the display, while the laser display is based on RGB three primary color light source (also a monochrome laser light source), and compared to LED light source In other words, the narrower spectrum laser has a more pure color display capability, which in turn can display a wider color range.
In a professional-grade cinema laser projection system, a RGB three-color laser source projector can achieve the BT.2020 color specification, which is 150% of the NTSC color space. In domestic laser display devices, because the cost-constrained technique is often a single-color laser plus phosphor technology, even though its color gamut space can meet the DCI-P3 standard higher than that of NTSC, it is more than sufficient to achieve a wide color gamut NTSC space.
At present, the main brand of domestic laser display is our familiar brand, Hisense, whose laser television product line has undergone two generations of products. From the initial 1080P to the current global launch of 4K DLP laser technology, Hisense Laser Cinema TV has a new presence in this new field. Advanced technical advantages.
Well, here's where the laser technology goes, and we're going to take the lead on this review. The laser theater TV model LT100K7900 is already Hisense's second-generation laser product. It is also the world’s first DLP projection equipment with 4K resolution. TI’s selection of 4K DLP chips on Hisense laser TVs proves that this DLP camp is unique. Suppliers are optimistic about laser technology.
Laser TV is more suitable for giant screen than flat-screen TV
Laser TV not only has the characteristics of high brightness and wide color gamut. Compared with flat panel TVs with LCD or OLED structure, the "screen" is lighter and has only 1/10th of the weight of Hisense laser TVs of the same size. Easy to move into ordinary people, before a certain brand 120 inches need to remove the window rental car from outside to move into the living room, and laser television can be directly from the corridor into the house.
The best large screen split structure Hisense laser TV appearance Appearance is not difficult to see from the appearance, a set of Hisense laser cinema TV by the screen, host and audio, it does not require a very narrow frame or full metal back plate material process to create a sense of quality When the wall of a living room is filled with a screen of about 2.3 x 1.3 meters, the laser television will be enough to demonstrate the professionalism and quality of your viewing equipment, not to mention the 5.1-channel audio at the screen.
100-inch unplugged screen

The biggest difference of Hisense's laser TV screen is that it has no electronic structure at all. It is a passive screen and can be understood as a projector screen. This 100-inch screen is roughly two iPhone 6s thick, with metal-brushed panels on the sides. In the absence of picture output, the screen of Hisense's laser television is gray instead of the black color of the LCD TV, which is somewhat similar to the high-end metal gray screen.
Judging from official information, this is a Nephi Passive Bionic giant screen, Baidu search Nefir is the most relevant term is the lens, or the Nephel technology terminology of Hisense laser TV refers to the special oblique light reflection structure on the screen surface. They can convert the light from the projection host to the screen and convert it horizontally into the human eye.
This kind of reflection imaging is close to the visual principle of the human eye to see things in nature. The light shines on the surface of the object and reflects into the human visual system imaging. The bionic structure of Hisense laser TV is lower and more healthy than the direct illumination of flat panel TV into human eyes. This is why bright projection screens don't feel dazzling, but turning off the lights at night can make you uncomfortable.
4K resolution 50cm projection 100 inches screen
From a certain point of view, Hisense laser TV is also a kind of split TV. In addition to its main computer responsible for data operations and signal output, image projection is also done via the host computer. This laser TV host with dimensions similar to the XL version of the power amplifier has a built-in quad-core processor with a dual-core A17 and A7 architecture and a 4-core Mali T624 GPU. The system memory is 2.25GB, and supports dual-band wifi and Bluetooth connectivity. In the interface configuration, the laser TV provides three HDMI (including HDMI3.0), three USB (two front USB2.0 and one rear USB3.0) and some audio and video and audio dedicated interfaces.

In terms of the optical structure of the host computer, it has built-in an imaging structure of a laser light source plus a fluorescent color wheel, and the light source and color optimization technology are independently developed by Hisense. The specifications given by the official show that color gamut coverage is as high as 116%, which is wider than the quantum dots TV with the highest color gamut. Because of the built-in TI 4K DLP chip, Hisense Laser TV can output native 4K resolution and supports shutter-type 3D display.
Unlike conventional projection equipment, the projection ratio 0.24 of Hisense laser TVs can display 100-inch large screens in less than 50 centimeters. Therefore, we can see that laser televisions and passive screens are placed very close to each other. I am worried that my family will be disturbed by the interference between the projector and the screen or the bright light will shine into the eyes.
Standard professional 5.1 audio system Hisense laser TV audio combination (in order to show convenience, I will put two back around the television to take pictures)
Hisense laser TV's standard solution includes a 5.1 audio system, which consists of an 8-inch subwoofer, a Soundbar over 2 meters (which can be split into two front speakers), and two back surrounds with a stand. Is a set of very standard 5.1 audio, the number of speakers and placement of the layout is very professional. According to our understanding, the speaker's power is as high as 160 watts. The abundant speaker size and power output provide space for its high, medium and low frequency.

In addition, you need to know that this set of audio does not have to be used with a laser TV. When the host is not powered on, it can enter an independent Bluetooth mode and connect to other devices such as mobile phones or computers to play music.
The quality of the intrinsic wide color gamut and high-dynamic laser television picture quality is the core concern of Hisense laser TV. For the new technology laser, we are also looking forward to its experience. The reason for emphasizing the experience is that the color gamut testing instrument we use in TV test is not suitable for projection equipment. Therefore, there is no theoretical test value for color gamut in the evaluation. This part of the content will be explained by subjective description.
Brightness is high enough, as bright and bright as a light
The measured brightness of Hisense Laser Cinema 2689 lumens is already very close to the official nominal 3,000 lumens, which is a superior performance of home projection products. However, you may not have an intuitive understanding of the brightness values, so we shot a screen shot of a 55-inch Hisense TV and a laser television in the same frame. As can be seen from the picture, the laser TV exposure is slightly lower than the 55-inch TV from Hisense, but it is already very close. Even when the light is on, the brightness is still close to the LCD TV. The color and contrast are not reduced, which means that we can use it during the day. .
Color style close to real no transition rendering


In terms of color, we use the "Honesty" Hobbit to test its color reproduction ability in New Zealand's natural landscape. From the perspective of the three red, green, and blue color scenes in the screen shots, the color trend of Hisense's laser TVs is a natural and not too saturated style. So perhaps the laser television is not the kind of bright and pleasing likable style, but it is more resistant to this reality, and reduces the loss of detail and distortion caused by high saturated colors. From the first picture of the grass, we can see that different levels of green are properly differentiated and expressed by Hisense laser television, and the texture of wooden fences and figures is very real, and there is no rich “digital taste”, which is the LCD Some fanciers in the era are looking for the screen effect.
Optically Controlled HDR Fragments Demonstrate Ultra-High Contrast In traditional TV picture quality testing, light control is a very important item. However, for laser televisions, it does not have to worry about light leakage. As for the contrast part of the light control, we chose to experience the fantastic drift of the HDR propaganda juvenile school. Many of the scenes in this film took place during the night. The high-light plankton added to the special effects contrasted sharply with the deep sea and night sky. In such a large light scene, Hisense's laser TV can accurately display high-bright jellyfish and stars. However, dark field sinking can surpass LCD TVs. Deep black images are not brightened by the surrounding high-luminance objects.


In another cruise scene, the foreground illuminated by the candlelight is very bright. In the background, the statues on the ship are evenly graded from bright to dark in the faint candlelight. As for the night sky, a number of stars are highlighted in the deep black, and these details are all given by Hisense. Laser TV accurately restores the display.
Large-screen and MEMC bring high dynamic experience
Because there is no problem of deflection response of liquid crystal molecules, dynamic effects laser television also does not have the concept of tailing that we often say. In 24 HD test strips, the contours of fast moving trains are clearly visible. In addition, because of the large size of the 100-inch screen, the details of the character in the window are also more legible than the usual size of the TV. Hisense Laser TV can present the user with such clear details of the movie as well as its 4K resolution and MEMC motion compensation. relationship.
4K resolution display
The Hisense laser television with a physical resolution of 3840×2160 is consistent with the current mainstream ultra-high-definition TV targets. However, in the projection category, 4K can be a very cutting-edge technology. For clarity, we chose a 55-inch 4K LCD TV in comparison with Hisense Laser Theater. The playback source is H.265-encoded 4K video. From the pictures, the detail sharpness of the two screen shots is basically similar. For a 4K display where the distance is closer to the senses, it is possible to experience the super clear effect by comparing the clarity with a television at a distance (3 meters or more for projection).
Multiplayer enjoyment Hisense laser TV VIDAA system experience TV in the family is the meaning of sharing, which requires the TV built-in video resources for family members of all ages to watch and entertainment needs, but it also needs to make it easy for everyone operating. In both respects, Hisense's laser TVs have performed outstanding tasks. Hisense has 22.22 million smart TV users. From the first-generation VIDAA intelligent system to the current VIDAA3, both the content service and the convenience of operation are already perfect.
Hisense VIDAA3 intelligent system smooth operation of a key to direct
Hisense VIDAA3 system's control logic is very simple and easy to use, combined with its "one-button direct" remote control, the user can enter the corresponding "live TV, get good-looking (video on demand)", through the four buttons on the remote control (Games) and Gathering (System Applications)." So, in my opinion, Hisense VIDAA3 system can bring a more rapid and direct operation experience, and these four shortcut operation settings almost satisfy most of the needs of smart TV.
Massive library definition up to 4K
There is no doubt that the most important function of TV is to watch video programs, whether live broadcast or on-demand content via internet platforms. On-demand video library, Hisense laser TVs cooperated with iQIYI, Tencent and other video platforms have more than 1 million hours of genuine film and television works, including more than 15,000 movies, more than 150,000 episodes of TV dramas, and massive animation and documentaries. The type of video content, high-definition film source accounted for 90%.


From an experience point of view, VIDAA3 of Hisense Laser TV has already divided different movie and TV categories including high scoreboards, animation, comedy, and science fiction. In the movie category, Hisense's content operations team also plans movie recommendations with different themes, such as the BBC's selection of the greatest films of the 21st century and the science fiction films of aliens invading the earth. Want to bring a TA to" usher in a video tour. The TV dramas are also divided in great detail. Historical fans can enjoy passing through various eras in historical costumes. Fans who like to burn brains and suspense can continue to be affected by the intense story in spooky warfare.

In terms of definition, Hisense laser TV can be broadcasted on demand to 4K movies and TV dramas, which will expand the practicality of 4K display devices and allow users to watch the ultra-high definition movies in minutes. By the end of the evaluation, there were more than 130 4K video on-line laser televisions, and this number is still growing.
Tencent PC games can play all

Hisense Laser TV has more than 5,000 games provided by partners such as Tencent and Gameloft, covering many different types of leisure and sports, such as the national landlords and many of Tencent’s daily parkours. For serious game enthusiasts, no Android game can satisfy these harsh people, and Hisense laser TV even has PC games built in it. Assassin's Creed, Prince of Persia, and supercar racing are the mainstream types of gun games and other first-line games. And you can enjoy PC games on a 100-inch screen without connecting to a computer. This is a top experience that most smart TVs and even low-profile computers can't bring you.
Teaching of full-age teachers from toddler to senior high school


For the group of children in the home, the polyhedron in the Hisense Laser TV VIDAA3 system provides educational content from infants to senior high school students of almost all ages, all of which are provided to the user in the form of teacher video teaching. The content includes all subjects except for the number of words. According to the Mathematics Curriculum for Senior Teachers of Xicheng District that we experience, the monthly price of 60 yuan is only equivalent to 2 yuan per day, which is more economical than those of the private tutoring classes, and this form of homeschooling is more efficient and does not require Return to commuting and waiting for classes, feel free to learn at any time to select a national teacher video class. If you purchase laser TVs and other Hisense TV systems, do not miss this polysocial function module.
Unbreakable teaching In the age of mobile internet, this generation of children has also begun to contact electronic screens earlier. Even children born in recent years have already started to touch mobile phones or tablet computers in early childhood. Vision problems cannot be ignored.
The eye-protecting advantages of Hisense's laser TV lies in its “unplugged screen”. The laser TV will not vertically shine the backlight into the eyes of the viewer like the LCD TV. The imaging principle of the LCD TV is bound to make the visual system feel the light. We Adults watching LCD TVs can obviously feel dazzling (especially nights with low light or even after turning off the lights), not to mention the children who are still in visual development.
Laser TV adopts “reflective” imaging similar to the principle of human eye imaging. The light is reflected obliquely upwards to the passive screen after being reflected by the reflector, and further reflects the final exposure to the human eye imaging. It is just like the natural light does not shine originally. After the object presents the same light and color, so that Hisense laser TVs are more eye-safe than traditional LCD TVs.
Experience overseas purchase on 100-inch giant screen


Under the multimedia TV module, Hisense has prepared different recommended products for users of all ages in the family. You can think of hot-selling products that can be found in the mall, and even Haitao Mall, which is directly purchased by Korea. In the online purchase of laser television, people only need to click to purchase, but scan the QR code in the mobile phone to save a lot of interactive steps that the TV remote control is not good at. The entire purchase process is very fast and convenient.
Experience Summary With the light of Hisense laser TV, I also experienced the future of display technology. There is no doubt that Hisense laser TV is a product that is more suitable for replacing the living room TV than the traditional projector and large screen LCD. It has a bright, high quality and longevity, easy to use many new era features, lightweight hardware structure also Solved the trouble of the second decoration of large LCD TVs.
On the other hand, compared with traditional living room TVs, Hisense laser TVs have a stronger competitive strength. First of all, comparing the price of LCD TVs with the same size of several hundred thousand yuan can realize the closeness of the 70,000-yuan laser TV. At the image quality level, the wide color gamut and high-contrast images brought by lasers break through the technical barriers of flat-panel televisions and make the visual senses more realistic and natural. In addition, the genuine video library and operating system built with the amount of 22.52 million Hisense smart TV terminal users allow family members of different ages to get along with laser televisions, and expand the life of laser television and audio in the age of application.
From the perspective of product power, Hisense laser TV is absolutely excellent. However, there is still a need to face the rumors without a summary. This huge screen TV set with 4K, laser and other cutting-edge display technology is destined to be cost-effective. The only uncertain factor is whether or not you can accept its market position, without doubting whether laser TV is good enough.
