Minimalist & low-key industrial design
Under the low-key and extremely simple appearance of the Z9D, it is the pursuit of various materials and processing techniques. For example, in its border part, in addition to using more textured metal, it also uses a golden color scheme that Sony rarely uses on television sets, revealing a hint of luxury in the main colors of dark gray. As for the appearance of the Z9D, what kind of process, what kind of material, and how many processes are used to create them, according to Sony's consistent style is not to be advocated to the outside world (if it is replaced with an Internet brand, most consumers will Has been brainwashed by various new terms, so we only need to feel through sight and touch. A good product can speak for itself.
At the same time, we can also find some very classic, Sony BRAVIA family elements under the minimalist look of the Z9D. For example, breathing lights that have never changed, suspensive pedestals, and even some old-fashioned multi-key remotes... all of these allow Sonyâ€™s old users to find the familiar feeling in the first place. Users also have the opportunity to experience the heritage of Sony's industrial design.
Black technology must mention: BacklightMaster Drive
First of all, the biggest breakthrough in the hardware part of the Z9D is the transformation of the LCD's key backlight structure: the new "Backlight Master Drive". The strength of this backlight is: 1, the use of ultra-high density direct matrix LED backlight (although in the end how many LED particles Sony does not explain, but from its performance will never be a small number, behind (There will be evidence); 2, it can achieve independent brightness and brightness control for each LED particle, and is based on real-time video signal control; 3, in order to prevent the light interference between the LED particles, specifically designed a The bundled structure allows each LED's light to shine only in the corresponding area.
Recalling the history of the development of LCD TVs, there have been products that have adopted direct-lit LED backlights, all of which have become a classic. However, in the traditional direct-type LED layout, in addition to the small number of LED particles, and due to the limitations of the backlight drive technology, the so-called dynamic backlight control can only be divided into a number of small areas in accordance with a certain area of â€‹â€‹the backlight control, ranging from a few, if It is already possible to achieve dozens or even hundreds of districts, and the Z9D can do it. In the past, no opponent has ever appeared.
I had seen the power of Dynamic Backlight System - Master Edition at CES this year: At that time, Sony placed two master LCDs with dynamic backlight system side by side, but one of them removed the liquid crystal layer, leaving only the backlight system. In this way, people can intuitively see the working status of the backlight when the television is displaying various screens. The effect is indeed very shocking, because it looks like watching a black and white TV screen with a slightly lower resolution, and the accuracy of its backlight is evident. And another advantage of this high-density LED layout is that it allows brighter parts of the image to achieve higher brightness, which is why the Z9D's HDR performance far exceeds the average HDR TV.
Three new feature-capable X1 Extreme chips
Another comparison of the Z9D has been neglected, but the technology that plays a role in no less than the importance of the backlight system is the integration of the three new technologies of â€œHDR dynamic item-by-item remodeling technology, dual image database, and SuperBitMapping 4K HDRâ€. "4K HDR image processing engine".
X1 Extreme's computing power is not used to run points. It is entirely for processing images. Therefore, it can achieve frame-by-frame processing of 4K resolution video signals.
The first new technology: "HDR dynamic item-by-item reshaping technology" can detect and analyze each object in the frame frame by frame and give the best optimization algorithm. After optimizing the details in each frame of the image, the image engine performs HDR shading adjustment according to the overall contrast of the frame. After two rounds of optimized remodeling, the image shows not only the light and darkness of the detail part is more true, but also can show more excellent light and shadow effects and contrast of light and shade, gradual change of light intensity and even halo performance at the overall macro level. It is difficult to achieve on ordinary HDR TV.
The second new technology "Dual Image Database" is one of the souls of Sony's image processing technology and is mainly used for noise reduction. Compared with Sony's past noise reduction technology, this technology can realize the recognition of different elements in the image such as foreground and background, and compares and reduces noise through a huge image database. In fact, on the Z9D launch event, many people have seen the difference between the noise reduction effects of the ZQD and the mainstream QD TVs and OLED TVs on the market. The effect even exceeds the OLED TVs known for their darkness. The reason is that OLED TVs are In the absence of high-performance noise reduction processing technology, it is easy to display noise as a video signal, which affects the performance of the dark part.
The third new technology is a 4K HDR 14-bit smooth gradient. Many people have had the experience of seeing a noticeable color gamut on the screen of a television screen. The main reason is not that the color expression of the screen is not enough, but the lack of color management capabilities behind it. The 4K HDR 14-bit Smooth Gradient Technology analyzes the image frame by frame and performs 14-bit smoothing of the image to fully optimize the gradation and achieve a lower gradation, which means a more natural color transition.
The five factors that affect image quality are: spatial resolution, temporal resolution, color gamut, brightness range, and grayscale range. To evaluate Z9D from these five dimensions, it not only has a balanced overall performance, but also has a high standard for each single item. Do not want to use too much vocabulary to praise the Z9D. I just want to suggest that AV lovers and HD enthusiasts have the opportunity to go to the store to see the true picture effect of the Z9D, because this TV can tell you that the highest level in the industry is now What is the picture quality?
The Z9D has an impressive and memorable color expression. This is an exaggerated and contrived color style. It looks both pleasing and real. The Z9D can also accurately reproduce any subtle changes in color and light and shade, and can even respond to challenging scenes with great brightness contrast like active display devices. It is hard to imagine that it is essentially a Passive light-emitting LCD TV. The Z9D also retains Sony's quintessence in color tuning. It not only provides ordinary users with a wide range of professional-grade image mode choices, but also provides professional users with a high degree of freedom for personal tuning in the later stages. The overall performance is nearly perfect.
The new Android system intelligence is no longer a short board
Compared with various "black technologies" on the picture quality, although the performance of the Z9D in smart features has not been significantly ahead of this era, experience still feels like the best system Sony has ever used. The Z9D uses Andriod TV6.0 platform which is specially adapted for large screens by Android, but it retains some features and habits of Sony since the XMB system in terms of UI style including manipulation, whether it is fluency or ease of use. In addition, compared to Samsungâ€™s Tizen system and LGâ€™s WebOS system, Androidâ€™s richness and extensibility performance will be even better. Z9Dâ€™s choice is also wise.
Summary: The best 4K HDR TV
The appearance of the low-key Z9D is absolutely the most advanced image quality performance. The Sony Z9D has reached a level that is difficult to reach in general LCD TVs in every aspect of the quality of the picture, such as brightness reproduction range, smoothness of color gradation, detail definition of 4K images, and color expressiveness. Even with dark display effects, even noise reduction circuits and powerful backlighting systems have not lost the performance of OLED TVs with inherent advantages. After reading the Z9D's picture, the personal feeling is that the picture is very comfortable and balanced. Second, the picture has a sense of reality that is hard to describe in words. This feeling has never been experienced in other TVs.
Finally want to talk about the price of Z9D. When the listing price of Z9D was announced, someone spoke to be expensive. Indeed, the prices of 65å‹32999, 75å‹43,999 yuan are really too much more than those of the Internet brands 65-inch and 70-plus TVs that are just a few thousand pieces. And the appearance of the Z9D doesn't look cool at all. Here I just want to say that 1, the price of domestic Z9D is actually very kind, do not believe you look up its offer in the United States, on average more than 10,000 more expensive than domestic. 2, this price, absolutely worthy of its performance. In the end, I strongly recommend that you have a chance to visit the Z9D's real picture in the store. This TV can tell you what the highest level of quality in the industry is!
