IT168 evaluation TV screen after experiencing the transition from CRT to plasma to LCD era, seems to have some stagnation for a long time recently, subject to the limitations of the liquid crystal itself, in size, power consumption, technology, etc. Already approaching the limit, then we can not help but ask where is the future of television? Is it the organic OLED, Quantum Dot or other that has recently been stir-fried? Hisense, one of the leading color TV manufacturers in China, has also given its own answer to the use of laser television as an important development direction for TV in the future and promote it vigorously.
　　 At present, Hisense laser TV has developed to the third generation. In addition to the new appearance and performance enhancement, the resolution of the new product has been upgraded to the 4K level, bringing the ultimate viewing experience. In addition, what's different about the latest 4K laser TV? Today this new product has come to our evaluation room. Here is a detailed evaluation for you.
What is laser television?
I believe that most people still do not understand the concept of laser television, so here I still briefly explain it, laser television is simply similar to the principle of the projector, this technology must first digital signal processing, and then Project light through a series of complex lenses. It is a digital micromirror device (DMD) developed by TI (Texas Instruments) to complete visual digital information display technology. Specifically, DLP projection technology uses digital micromirrors (DMDs) as the primary key processing element to implement digital optical processing.
Therefore, in terms of the lighting principle, there is an essential difference between a laser television and a conventional TV. Traditional LCD TVs emit light through a backlight, and then the liquid crystal molecules deflect to achieve image display, and the laser TV projects light onto a medium (such as a wall, The curtain, etc., transmits the image to the human eye through the reflection of light, and can project a large 100-inch screen at a very short physical distance.
　　 Now that we know the principle of work, we can roughly outline its advantages over traditional TVs. First, the lifetime of laser light sources is much longer, and the brightness is reduced to 80% of the previous time. It takes almost 50,000 hours; the second is brightness. With high color and wide color gamut, the official nominal brightness of Hisense 4K laser TV reaches 3,000 lumens, and NTSC with color gamut coverage rate of 116% is more outstanding than OLED and quantum dot TV.
Why do laser TVs? Where are the advantages of Hisense?
Many people will say that the current price of LCD TVs is already so low. Why does Hisense still insist on pushing laser televisions? In fact, most people's needs are only below 60 inches, which is not the market for laser TVs. Looking at the field of large-screen televisions over 80 inches , the price has been stubbornly high, and the quality of laser televisions is comparable to LCD TVs. More importantly, the price is only 1/3 of that of LCD TVs of the same size. A brand new cost-effective solution.
At the same time Hisense 4K laser TV also broke through its three major technical difficulties: First, the use of high-processing optical engine, its processing power than the 2K laser TV products increased by 300%, thus achieving the 8.3 million beam of fine control, to achieve 830 Megapixel image performance; Second, 4K laser TV needs high-resolution lens design, Hisense 4K lens achieves 186 beams per millimeter of optical resolution; Third, 4K laser TV manufacturing to achieve micron-level material control accuracy and lens Accuracy adjustment, Hisense 4K laser cinema TV uses a high-precision manufacturing process, mechanical processing to achieve a close to the limit of 10 microns accuracy, lens adjustment accuracy of 5 microns, the error is less than 1/20 of a hair diameter. Together, these contribute to the unique advantages of Hisense laser TVs over other products.
100-inch giant screen does not take up space
Hisense 4K laser TV includes screen, mainframe and audio. The screen part uses a 100-inch large-scale imported Fresnel passive bionic screen. The rare-earth process is made of rare metals. Such a large screen also has a very narrow border. , it really brought a very shocking sense of presence and immersion. Of course, the most important feature of this bionic screen is its soft viewing effect. It overcomes the problem of traditional electric video flash, natural comfort, and can also shield the ambient light, and different projections, can also be viewed in bright light, And the color performance is better .

　 　 Superior to ordinary LCD TV picture quality testing
Due to the different lighting principles, we cannot use the test equipment for testing ordinary TVs for testing. Therefore, we specifically use the projector's test standard. For this product to be tested, the test link includes objective data and subjective perception of two parts, of which the objective test part we tested the maximum brightness of the product, is the projector in the brightest mode ( Brightness, contrast, and lamp mode are adjusted to the highest average picture brightness. From the results of our actual testing, the maximum brightness of Hisense 4K laser TV reached 6,400 lumens, which has greatly exceeded the nominal value.
