You can experience the big screen and viewing feeling of IMAX cinema at home. I believe it is the dream of many people, but the reality is very skinny. After all, not everyone can build a video and audio studio at home. Although the picture of the traditional large-screen TV is big enough, the effect is still very different from that of the cinema, and watching it for a long time may also cause harm to the eyes.
In fact, in addition to traditional TV, if you want to build a family's "IMAX cinema", there is another choice-laser TV.
When it comes to laser TV, we must not be able to bypass the brand Hisense.
As a leader in the laser TV industry, Hisense has applied for more than 2000 core technology patents, ranking first in the laser TV track for many years.
Speaking of which, you may wonder, what is laser TV? What are the advantages of Hisense laser TV?
Next, CTOnews.com will have an in-depth experience around Hisense laser TV 100L8K. Let's take a look at how 100L8K uses a laser TV to achieve your living room IMAX cinema!
What is laser TV? Laser TV adopts the principle of reflection imaging, and the laser light source is emitted by the host computer and imaged after the reflection of the screen.
However, to say but here, we must not confuse laser TV with "large short focal projection", because morphologically, laser TV also needs to include mainframe, screen and other core devices, and some models will also have external acoustics. from a technical point of view, laser TV is much more complex.
Secondly, and most importantly, Hisense laser TV meets the requirements of the definition of "laser TV display equipment" in the industry standard "Laser projection display Specification for TV receiving equipment".
This industry standard, equivalent to a laser TV threshold, is directly related to the final picture quality of the product, less than the standard projection products can no longer be sold in the name of "laser TV".
In other words, there is a clear boundary and a clear division between the projector and the laser TV.
In terms of product advantages, laser TV can project large-size pictures in a short distance, which does not need a long installation distance like the traditional projector, and gets rid of the space restriction of watching the large screen. At the same time, the brightness and contrast of laser TV are also better than traditional projectors, and a unified anti-light screen, the effect of these screens is often better than that of large white walls or curtains.
Due to the low aggressiveness of the laser TV reflection image, compared with the LED backlight of the traditional LCD TV, it is not dazzling up close, has the advantage of healthy eye protection, and can watch big scenes in a small space.
Second, why to evaluate Hisense laser TV 100L8K? Hisense can be said to be the leading brand of laser television. in terms of technical research, Hisense is the earliest manufacturer to study laser display technology in China. As early as 2007, Hisense set up a professional R & D team of laser display technology and products. Applied for more than 2000 core technology patents in the world. Technology first and accumulation, so that Hisense can maximize the advantages of laser TV products.
Hisense laser TV 100L8K said from the product model: 100L8K is the strongest comprehensive configuration of Hisense laser products, set the latest generation of LPU digital laser engine, home integration advantages, the highest color gamut in the industry, Harman Catton sound, multiple eye protection technology in one.
The LPU digital laser engine of Hisense Laser TV 100L8K brings the shocking visual effect of "movie primary color" on the basis of the giant screen, which can be said to be the optimal solution of the living room IMAX cinema.
Needless to say, next, let's enter the evaluation experience of Hisense laser TV 100L8K.
Third, experience link 1, the appearance starts from the appearance of Hisense laser TV 100L8K.
Hisense laser TV 100L8K can be divided into three parts: laser TV mainframe, Fresnel passive anti-light screen, and matching Harman Catton independent subwoofer.
The host design of Hisense Laser TV 100L8K is inspired by the Opera House in Milan, Italy, with a square fuselage and a suspended shape.
Hisense laser TV 100L8K mainframe uses gray metal, vibrant orange line runs through the fuselage, there are breathing lights on both sides of the front, breathing light area hollowed out, and wrapped with light gold edges, there are hidden heat dissipation holes on both sides.
Directly above the fuselage is the light outlet of the main engine, which adopts an embedded design, and there is a wire drawing process with strong metal texture on the outside of the lens.
This set of meticulous design makes Hisense laser TV 100L8K look quite high-end, exquisite manufacturing ingenuity, more like a work of art.
This is also quite in line with the design idea of Hisense's high-end product line-the proper use of golden elements, which not only highlights the noble temperament, but also does not fall into the stereotype.
As far as this set of design is concerned, it is fully in line with the users who match the price.
Hisense laser TV 100L8K hides the interface at the bottom of the fuselage, in which there is a USB2.0 interface on the lower right side, and the remaining interfaces are located on the rear side of the fuselage, including HDMI × 2, 1-way support eARC,USB2.0*2, optical fiber * RS232*1 and so on.
These interfaces are sufficient for daily use. There is no pressure to connect to game consoles, or computers, speakers, or microphones, but USB2.0 still has transmission limitations, and it would be better to be able to access USB3.0.
The remote control of Hisense laser TV 100L8K also uses the design of the same color as the fuselage, mainly rose gold, elegant texture.
Hisense Laser TV 100L8K is equipped with Fresnel passive anti-light screen, which also corresponds to a 100-inch anti-light screen.
The 100-inch look and feel is quite shocking, although the specific concept of 100-inch can not be felt in the actual picture, but our tall 185cm editor, even standing next to the TV, is only as tall as the TV.
Thanks to the advantage of the super-large screen, the frame of the screen can be ignored by the naked eye at a distance of more than 3 meters. After lighting the screen, it is as if you are in a cinema with a giant screen. Let you feel the unprecedented shock and immersive experience.
Although there is no electricity on this screen, it is the existence of this screen that has become the most indispensable part of Hisense Laser TV 100L8K to watch blockbusters comfortably-the unique optical structure can prevent glare and bid farewell to the sense of mirror, which makes the laser TV 100L8K can watch 100 inches at a distance of 3 meters.
In the design, this screen because it is not electrified, does not need the circuit, the lamp bead or the loudspeaker inside, therefore can achieve the 15mm extremely thin fuselage, the frame is extremely narrow, the screen back is also the complete plane, after installation and the television wall has no gap, hangs on the wall like the mural, the degree of integration is stronger, can be better integrated into the home decoration environment.
Hisense laser TV 100L8K reduces the projection ratio to 0.22 1, and the mainframe only needs 21.3cm to project 100in pictures from the wall, further reducing the space requirement.
This is also an advantage of Hisense laser TV compared with ordinary projectors. If an ordinary projector wants to project a 100-inch picture, it needs to extend the projection distance, at least about 3m, and once the projection distance is extended, there will be all kinds of problems of projecting light shining on the human eye or being blocked.
Hisense laser TV 100L8K does not need to worry about the above problems, the host is closer to the wall, can be placed on the TV cabinet under the screen, of course, there will be professionals to survey and install. As a whole, the home decoration space is more friendly, and the degree of integration is higher, and there is no fear of light blocking annoyance.
In the system, Hisense laser TV 100L8K itself also provides human eye protection functions, such as when child protection is turned on, when someone is detected passing within a certain distance above the host, it will automatically turn off the host to prevent light from entering the eye.
Human eye protection
Child protection, finally, is the installation.
Hisense laser TV 100L8K provides a series of free premium supporting services, such as survey, installation, commissioning, etc., consumers do not have to worry about.
In addition, even if the position of the host is moved carelessly during daily use after installation, the projection screen can be automatically aligned with the screen by scanning the code and taking photos. The operation is quite simple, and there is no problem for the elderly to get started.
2. Eye protection the eye protection ability of Hisense laser TV 100L8K comes from two aspects, the first is the Fresnel passive anti-light screen.
The Fresnel passive anti-light screen equipped with L8K adopts the superimposed design of eight optical structure layers, which has a very strong anti-glare and low reflection effect, no matter during the day or night, in any environment, it can ensure that the sense of immersion will not be affected.
In addition, its screen matches the light path of the host one-to-one. If you look at it through a macro lens, you will find that the screen is not a flat smooth surface, but there are some fine semicircular structures. this can better achieve the upper, left, right, three directions of ambient light shielding, so as to reduce the impact of ambient light on picture quality.
(when the strong light shines on the screen from the periphery, you can obviously see the light resistance of the screen, and there is no dazzling and reflective phenomenon, which makes the naked eye feel very comfortable.) at the same time, the Fresnel passive anti-light screen itself does not glow. It is projected onto the screen by a laser light source, and then the light passes through the diffuse reflection of the screen and then enters the human eye.
As a contrast, the LED backlight used in the traditional LCD TV is to direct light through the screen into the human eye, resulting in a strong sense of aggression, so there are some problems such as dazzling when looking at close range and eye fatigue when watching for a long time. On the other hand, the image of laser TV reflection imaging has a low sense of aggression and does not dazzle at a close look.
To take an inappropriate example, the traditional LCD TV is like the sun, which glows itself and looks directly into the eyes, which is more irritating to the eyes. Fresnel passive anti-light screen is similar to the moon, reflects the light of the sun, reflects the image with a low sense of aggression and is naturally more eye-friendly.
In fact, in the author's experience, I can obviously feel the "soft" visual effect brought by this diffuse reflection, and feel comfortable and natural. Especially in the dim light environment, there is no dazzling feeling at all, which is an incomparable advantage over traditional LCD TV.
Hisense laser TV 100L8K eye protection ability, but also from the "0 harmful Blu-ray" advantage.
Based on the LPU digital laser engine, the spectral range of Hisense laser TV is very narrow (30nm), so it is inevitable that a large number of blue light falls into the range of 405~445nm, resulting in varying degrees of blue light harm.
In order to verify the "0 harmful blue light" characteristic of Hisense laser TV, we use harmful blue light test glasses to test.
Hisense laser TV 100L8K screen effect (left) | ordinary LED screen effect (right) under the observation of blue light test glasses, Hisense laser TV 100L8K screen can hardly see any blue traces. In contrast, the ordinary LED screen shows obvious blue polarization, and the harmful blue light is also more obvious.
This sharp contrast is enough to illustrate the advantages of Hisense laser TV in eye protection.
3. The Hisense laser TV 100L8K uses a panchromatic laser (red + green + blue) with a resolution of 3840 × 2160. The LPU digital laser engine controls light at the nanometer level, achieving a breakthrough of 8 million pixels, with the ultimate performance of high color gamut, high color accuracy, high dynamic definition and high perceptual brightness.
First of all, with regard to brightness, official data show that the brightness of Hisense laser TV is 350nit, while the peak brightness is as high as 380nit. Although some people may think that this brightness index is not too high, in fact, in the daily use environment, this brightness is enough.
Note: due to the limitation of gif format, the picture effect can not be fully displayed, the actual look and feel is normal, only for reference.
When the curtains are opened during the day, there is no pressure on the brightness of Hisense laser TV 100L8K
Open the curtains, turn on the lights, Hisense laser TV 100L8K picture is still clearly visible, such as the last two groups of GIF pictures, even in the daytime indoor lights or open curtains, the picture brightness is still very good, fully proved its anti-light strength, so the use of Hisense laser TV does not need to create a special all-black viewing environment.
At this point, it is also clear in the experience that Hisense laser TV is different from traditional projectors.
In terms of color, laser TV 100L8K has brought the highest color gamut in the industry-up to 110% BT2020 and Δ E ≈ 0.9, exceeding the film industry standard in an all-round way.
The three-color laser engine greatly improves the color performance of the image. You know, the color gamut standard adopted by laser TV 100L8K is BT.2020,BT.2020 gamut, which is far beyond our common Adobe RGB and SRGB, which is closer to the maximum color range that can be recognized by human eyes.
Through conversion, the color gamut of 110% BT.2020 is equivalent to 152% DCI P3 and 149% NTSC, which has far exceeded that of mainstream LCD TVs and OLED TVs.
Therefore, Hisense laser TV 100L8K can smoothly and exquisitely present the color of the original film, coupled with the advantages of a hundred-inch screen, as well as IMAX Enhanced certification, extend the high-end audio-visual experience of IMAX cinema to home entertainment, as if immersed in the movie, the movie-level experience is not exaggerated at all.
We have shot several groups of 4K sample films, you can have a brief experience:
From the actual experience, Hisense laser TV 100L8K presents a very excellent picture color, look and feel full, pure, there is no gray phenomenon. With the help of the AI algorithm of LPU data laser engine, Hisense laser TV 100L8K also avoids unnecessary particles and noise in the image as far as possible, making the picture more transparent and clear. And even in the bright indoor environment during the day, it can still present an amazing 4K HDR picture quality.
4. The measured sound quality is the same as the picture quality, and the sound performance of Hisense laser TV 100L8K is even more impressive.
In terms of hardware specifications, the combined power of the whole system is as high as 120W, 7 speakers and 3-way power amplifiers. The mainframe adopts explicit sky sound, treble and full-frequency loudspeaker design, which makes the sound level and position feel stronger.
In the subwoofer section, it is equipped with a separate subwoofer that can dive to 40HZ, as well as sound support such as Harman Golden ear Master tuning and HI-SOUND Teana engine technology and DTS VmurX.
In terms of independent subwoofer experience, the Harman Catton sound system of Hisense Laser TV 100L8K is almost comparable to the 10,000-yuan-level home sound system, with 360 °surround stereo sound field, making people immersive and enjoy the pure extreme presentation of the original color.
In the old tradition, we first played the simple experience of the Eagles'"Hotel California". The three-band performance of Hisense Laser TV 100L8K is quite balanced, with strong and flexible low frequencies, while the middle and high frequency strings and vocal parts are clear, round and delicate.
What surprised us even more was the performance when the movie was played.
The audio recording of the Eagle band "Hotel California" We casually chose the recent hit blockbuster "volunteers" to experience the Logo soundtrack of the dragon label at the beginning, as well as the roar of the train after the opening of the movie, as well as string background music, which made people feel as if they were in the cinema, the sound effect was quite shocking, and the sound field was very strong, which filled the film with a sense of immersion.
