LeTV Super TV uMax85 Dolby Trials Dolby Vision Technology
The bold innovation in appearance is the first step in attracting more consumers' attention. The key to winning consumer recognition and achieving good results lies in the “hard power†of the product itself. Dolby Vision is currently the strongest software and hardware solution.
The first is the panel definition. With the optimization of the 4K panel and the Mstar6A938 smart chip, the LeVideo ultra-theater uMax85's display screen can naturally restore the picture while providing consumers with a more realistic and impactful visual experience.
Dolby Vision's Dolby Vision technology allows the screen brightness to be more than 40 times that of ordinary video, allowing users to experience a wider range of brightness dynamics, brighter colors and purer natural blacks. From a technical perspective, Dolby Vision is the highest standard for HDR technology. Especially when the Hollywood blockbusters are almost always equipped with Dolby Vision technology, choosing the UltraTV uMax85 means that consumers can truly feel the shock of Hollywood blockbusters. As the industry's hottest keywords in 2016, HDR performance of TVs has undoubtedly become the focus of consumers.
In fact, these are not the essence of LeTV Super TV uMax85, the product can achieve the core of Dolby vision is 448 partitions of light control technology. Dynamic zone light control technology can control the brightness of each LED backlight zone. The original digital-analog hybrid light control technology achieves 16-bit grayscale light control to enhance the brightness and darkness of the picture and display the layering of the picture more finely. .
Due to the different imaging principles, LCD TVs are inevitably subject to dynamic afterimages. For this reason, many LCD TVs have added dynamic compensation technology. For example, we introduced the UltraTV uMax85 in the same year. With the addition of Fluid Motion 1920 high-speed backlight control technology and MEMC dynamic picture processing technology, LeTV Super TV uMAX85 can effectively eliminate motion picture. The phenomenon of jitter, tailing, etc., optimizes the dynamic picture while bringing consumers an even more fluid viewing experience.
From the many technical introductions of products, LeTV Super-TV uMax85 can be said to be full of sincerity, creative process design combined with many of the industry's top black technology, for consumers to create a rare high-end products in the industry. So what is the real strength of music super TV uMax85? Later on, we will in-depth experience of LeTV Super TV uMax85, close to understand the unique charm of LeTV Super TV uMax85.
The Key to Realizing Dolby Vision: 448 Accurate Control of Light
As an Internet TV brand that starts with content and services, its powerful content strength does not need much to say. In today's product experience, the author only wants to talk about the performance of the product with the majority of consumers, after all as a display output. Equipment, the strength of the display capacity determines the final trend of the product in the market, then the music as super TV uMax85 performance in the end how?
The first is accurate light control technology. Consumers who understand the molecular structure of LCD TVs know that almost all LCD TVs cannot achieve precise control of backlight sources, whether they are direct-type or side-in. In particular, LCDs with side-entry backlights are more likely to suffer from serious lack of color purity and uniformity due to lack of controllability in light control. Although in this respect, direct-lit backlight LCD TVs perform better, but they can only meet the viewing needs of ordinary consumers. Once they encounter enthusiastic consumers who are “criticalâ€, they are comparable to the “disaster†quality. Performance is hard to impress enthusiastic consumers.
In order to enhance the precise control of the TV, the real and effective restoration of the image, LeTV super-TV uMax85 will be divided into 448 sub-standard LCD partitions, which is currently available on the market with the most control of light control technology. Through the digital-analog hybrid light control of the LEDs, higher and more detailed picture layering is achieved (this is also LeTV's patent, uMax85's housekeeping capability). Of course, one point that needs to be emphasized here is that the multi-zone light control technology must be implemented in a direct-type LED backlight LCD TV, and even a structured side-entry LED backlight LCD TV cannot achieve such effects.
Of course, there are also some cutting-edge products that incorporate regional light control technology. However, due to the very limited number of partitions, the actual performance of the screen cannot be compared with the 448 division-controlled LeTV super TV uMax85.
Not only that, LeTV super-TV uMax85 also added 4K MEMC dynamic image compensation technology, combined with 448 independent partition backlight Fluid Motion 1920 speed backlight control technology, can achieve accurate capture of each action, and the use of Fluid Motion 1920 high-speed backlight scanning Technology brings more fluid motion to consumers.
Dolby Vision's Most Powerful Video Solution Nowadays
In the previous article, we mentioned a very critical standard - Dolby Vision Dolby Vision. What is the standard and what impact does it have on the television industry? With questions, let's first look at the hottest keyword in the color TV industry in 2016 – HDR.
HDR is a high dynamic range, which can display more details of highlights and shadows, while bringing richer colors and more in-depth and natural details to the picture, thus making the television picture closer to the human eye. Due to differences in concepts and standards, the format of HDR is mainly focused on Dolby Vision and HDR10. What is the difference between the two?
As the leader in the development of cinema technology today, Dolby is the first HDR technology to be put into use. The core of this technology is the "perceptual conversion" (PQ) of the electro-optical conversion function, its biggest highlight is to customize the brightness standard in 10000Nits (normal TV brightness is only about 100-200Nits). But currently no display device can achieve this brightness, so the current Dolby Vision brightness target is a more practical 4000Nits. In addition, recordings made with Dolby Vision also include up to 12-bit color depth. From the standpoint of overall performance, movies processed and transmitted by Dolby Vision are the best in terms of sound and picture effects, which is very much in line with the demand for audiophiles' purchases.
However, since Dolby Vision's entire solution is designed with a large number of patented technologies, the cost is relatively high. In order to save the patent fee, an HDR10 evolved from Dolby Vision has entered the realization of people. As a "perceptual transformation" (PQ) based on the same core technology functions as Dolby Vision, the HDR10 is similar to the Dolby standard in brightness, color, etc. The only difference is that the HDR10 only supports 10-bit color depth and is a There are no hard level indicators for open standards, just support HDR10 decoding. Dolby Vision has rigid standards. The maximum brightness needs to reach a very high brightness, while the minimum brightness reaches a very low brightness, and the color information needs to support and support 10-12bit. The difference in this standard directly leads to the screen restoration accuracy is not The same day.
In order to facilitate everyone to have a clearer understanding of the two, the author here also made a summary for the majority of consumers.
First of all, from the point of view of the technology itself, the hardware solutions used by Dolby Vision are more advanced, and better restoration accuracy is achieved through frame-by-frame rendering. Secondly, in terms of actual results, the evaluation reports currently available all indicate that Dolby Vision looks more natural and there will be no HDR10 glare. Thirdly, the HDR10 has a wider range of options for content and peripheral support. It can use UHD 4K Blu-ray and enjoy online streaming media. Dolby Vision is currently only available through Netflix, VUDU and Amazon online streaming media.
It is not difficult to see that as one of the few top-level Dolby Vision standard uMax85 super-video in the image restoration, color performance, color depth contrast and other performance can be described as difficult opponent.
Comparison of LeTV HDR
Strictly speaking, HDR is not a hardware technology. We should think of it as a video format and concept. To really feel the perfect performance of HDR, you need to upgrade everything from content to hardware, that is, from the shooting, production, editing, transmission, and display of film and television content. Throughout the process, you have a powerful content production team and The music video streaming media CDN technology and high-end TV terminal design capabilities are undoubtedly the best.
As a flagship product, the LeTV SuperTV uMax85 perfectly supports the Dolby Vision and HDR10 dual-standards, and the wider dynamic range creates a perfect picture quality performance. In addition, in conjunction with the 1000Nit intelligent peak light control technology, the super-high dynamic contrast is achieved while taking into account the comfort of human eyes when viewed.
LeTV uMax85 supports DCI-P3 color gamut/10bit color depth, than traditional BT. The 709 standard has increased by 26% to meet the digital cinema-level colors and standards.
In addition, LeTV Super TV uMax85 not only provides native support for content, but also uses SDR-to-HDR processing technology for SDR content, statistical image grayscale and other color information, reconstruct image frame contrast, color, details, combined with the accuracy of the 448 partition Backlight dynamic control to achieve close HDR display.
As the author mentioned in the previous article, the HDR TV standards that are currently on the market are not the same, but the uMax85, which has dual standards, is not intended to have the highest standards. It is necessary to know that Hollywood movies are produced using Dolby Vision content. Method, so you want to see authentic Hollywood blockbusters, only choose to support Dolby Vision TV.
LeTV Super TV uMax85 hardware configuration hardware competition difficult to find rivals
Of course, in order to realize many of the above-mentioned performances, in addition to the continuous improvement of technology, the collocation on the hardware is also particularly critical.
