Sony Dharma second full flagship TV Z9D scene analysis

On August 10th, 2016, it was a memorable day for Sony Dafa. After the 1080P flagship TV HX950 and the 4K X9000A series, there were no models in the 14-year and 15-year C-tailed TV product lines that could surpass them. Even for some enthusiasts, Sony's TV is a bit "not as good as a year." However, this situation was reversed yesterday, the flagship TV Z9D let me wait for users to shine again by Sony's brilliant. The Z9D is not a new product that has compromised the market. Its appearance tells the industry to promote the OLED and quantum dot brands behind the scenes. You are still far behind.

Contrast products
Quantum dots and OLEDs are difficult to win

Since it provoked the war, let's make it even more prosperous, first look at Sony 65Z9D and a brand of quantum dot-core TV and another brand of high-end OLED product screen photo contrast (choose 65 inches maybe because OLED is difficult to measure Produce big screen).

Comparison of the details of the cloud parts of the three TVs
Pictured above is a video scene scene screen shot, a very sunny day, blue sky, white clouds, white buildings on the ground are in high light, the shadow of the building in the foreground is the dark part. The first thing that can be seen most clearly is that the middle Z9D is significantly brighter than the left quantum dot and the right OLED TV. When you look at the details, you can also find that the Z9D with the highest brightness in the middle can display white clouds with richer brightness information, especially in the top left corner of the screen. The contrast between the clouds is clearer and more real, and the other two TVs are The limitations of the backlight cannot show the light ratio in a small range of scenes.

100% cut ground scene contrast
In addition, we can also see that the difference between the three TVs in the shadows is not obvious, but on the expression of the white buildings outside the shadow, Z9D's “sunshine sense” and the detail reduction ability are obviously better than the other two models. The left side is yellow. The smooth light and backlight of the building are also obvious.

In addition to the color and details of the petals, you can also look at the transparency of the right plastic sheet

We can see the color and details of the three TVs in the contrast scene of the above color. The left side is the quantum dots. In terms of technical specifications, its gamut coverage should not be lost to Sony. However, you will find petals of different colors. The details are obviously worse than the middle Z9D, and even a lot of petals are already integrated. Although the color of the TV can be displayed in a wide range, the level of color (color depth) is not satisfactory.

Because of the limitation of the exposure range of the same photo, OLED TVs are even more ugly. The color details of the OLED TV are more abundant than the Quantum TVs. However, when the three cameras are photographed together, the OLED is really too dark. The light and shadow atmosphere is its weak point. .

-- No plan below --

The above is just a technical demonstration of the demonstrations outside the “Little Dark House.” In the dark room where the venue was built, we saw clearer, more specific differences and display characteristics of the three TVs. Because of the reasons for not taking photos, the following are just my memories and dictation.

In a night scene demonstrated in the small dark room, because of the noise in the background, OLED TVs did not show a pure black field as we imagined, and even the nighttime "black" sky was already somewhat grayish. Due to the lack of backlight partitions and the fact that curved display backlights are not easily distributed evenly on the QDs, there is a noticeable backlight allocation in a certain area of ​​the screen. It still stays at a stage where it is necessary to enhance the light control capability. The performance of the Sony Z9D is significantly higher than that of the other two televisions. Through the comparison and matching of the advanced version of the X1 image processing chip with the image database, it is possible to calculate the details of the sky and the actual scene in the screen, and treat the sky as pure. Background color or black (late night) can also perform multiple image quality processing operations on objects that need to be preserved, so that the backlight output of the sky portion can be controlled and optimized for other effective image information.

There are many scenes that can show the differences between the three televisions. For example, in the backlit lens of a movie clip, the Z9D can fully restore the sun's own light and the halo level of the sun, while the other two TVs exceed the peak brightness. The range that can be expressed, the sun becomes more like a bright sphere, the sun blends in with the surrounding halos, and the light and shadow levels are lost. In this scene, the flare phenomenon brought by the backlighting of the three TVs is also more true for the Z9D restoration.

Three televisions put together to play the same video content to see their advantages and disadvantages, and in the quality experience we experience, the Sony Z9D is in terms of color accuracy, HDR effect, contrast, sharpness, detail and so on. Overall better than the two competing models, this is not negative it belongs to the Z series of Sony's high-end products. However, it needs to be pointed out that Xiaoheiya has already had no comparison of dynamic processing in all the demonstration sessions on the site, and it is not known how much it can reduce the gap with OLED (dynamics are the most insurmountable technical limitations of LCD TVs).

Compare yourself

The existing flagship 75X9400D also has a clear gap



Left X8500 Right Z9D
When faced with other competing brands, this is the case. How different is the Z9D and its own products in Sony TV's own PK? There are two experience areas in the scene. First of all, it is compared with our own 75X8500D. Like the difference we see on the screen shot, the light ratio of the two TV sets is very different. The Z9D on the right is significantly better than the left X8500. .

Left: X9400 Right: Z9D

This big difference is a bit like SDR vs. HDR.
Even in the face of the active flagship 75X9400D (X9300D is a dynamic backlight master of indirect backlight architecture) with a direct backlight system, we can still see the obvious difference between the two TVs from the light and shadow details. For example, the above screen image of the outdoor character scene, the most obvious place is the brightness of the left side of the plant on the light side, the right side of the Z9D more dazzling "sunshine sense." In addition, when you pay close attention to finding people's headscarves, necklaces, aprons and other places, the Z9D will be brighter and the scene will be more three-dimensional because of the higher light rendering. In a word, the Z9D is closer to the actual natural performance. Progress was brought by the Sony Z9D Dynamic Backlight System - Master Edition.

In this scene of sunset scenery, the foreground grass color and details, the plants in the center of the screen illuminated by sunlight, and the color saturation of the evening sun can be seen in the advantages of the right Z9D compared to the X9400D. .

Analysis of Sony Z9D TV Technology

"pixel-level backlight" dynamic backlight system master version

After describing the upgrade of the Z9D Contrast and Sony’s current high-end TV, we went back to see why it was so dazzling. In addition to Sony Watchman's various terricolor similar to Terricolor wide color gamut, sophisticated light control backlight control, etc., with the Z9D comes from a set of LCD TV history, the most outstanding backlight system, dynamic backlight system - Master Edition let it Has a black field that can compete with OLED on the same stage, and is fully superior to the flagship TV that has a brand of quantum dots with a brightness of 1000 nits. To put it plainly, it means that it has the strongest brightness output of today's LCD TVs, and it does not lose the ability to control the darkness of OLEDs. The Z9D is the best picture quality in the history of Sony LCD TVs, and it is also the closest to today's professional television production monitor with the civilian television.

Advanced image processing chip X1 brings more sophisticated image analysis and processing capabilities
Dynamic Backlight System - Master Edition is a backlight system that can independently control the brightness output of each direct-lit backlight. It consists of a direct backlight with densely arranged rear panels and a new 4K HDR image processing engine X1. On the hardware, it realizes the independent control of each backlight source, and the software performs an HDR dynamic image-by-image reshaping, a 14-Bit smooth gradual change, and a dual image library image matching to accurately analyze each frame of the picture through an X1 advanced version that improves the 40% computing capability. Backlight composition.

Very dynamic level backlight distribution, even to optimize the light emission structure of the backlight in order to reduce diffuse reflection

Dynamic Backlight System Master Edition Backlight Control Demo
This backlighting system completely breaks down those LCD TVs that are so fine that they claim to have more than 200 or even more backlight partitions. Although the Sony technicians did not tell me the number of LED backlights for security reasons, you can see from the live demonstration that you can see Its backlight can adjust image contours similar to negative ones, which areas need to strengthen the brightness output, the surrounding brightness is excessive detail, the control of the dark part backlight brightness, and even the backlight of all areas under the black screen is turned off. Realized on the Z9D. If it is a direct type backlight of a traditional LCD TV, they will be divided into a number of rectangular areas, and the brightness output of a certain area will be controlled in a wide area in each "big" backlight partition. This is completely compatible with the Z9D's backlight partitioning and light control capabilities. It is the product of two eras.

Conscience Price

It’s not much more expensive than the competition or its own flagship.





The above is a "picture frame" style 100Z9D



65/75Z9D face looks similar to active duty X9300D/X8500D

Z9D TV prices
The above is the experience of Z9D TV on Sony's new fall conference. In the end, we talked about the price of Z9D TV. The Z9D series starts at 65 inches and the price is 32,999 yuan. This official quotation and comparison show that the QD TV is the flagship TV. The difference in sales price is 4,500 yuan. If you purchase 300 million top-rated TVs, the improvement in quality of the 4,500 yuan can be quite obvious.

Another 75Z9D price is 43999 yuan, which is actually not more expensive than the 37999 yuan Sony now 75X9400D. Regardless of whether it is competing products or its own model, we can see the conscience of Sony’s flagship TV. We must know that it is not much higher than the overseas prices of Japan or Europe and the United States. It is absolutely full of sincerity.

In addition, the price of the 100-inch version of the Z9D is not announced at the scene. If you are interested in buying and have money, you can wait until the National Day, when the most heavy-duty Z9D model will be on sale.

At the end of the article, let me briefly talk about Sony's 16-year high-end TV product line. The arrival of the Z9D has just brought Sony and South Korea's current flagship TV prices at the same level. In other words, before it, the price of the highest-end X9300D/X9400D as a whole is not too different from that of the Korean system. This may be due to cost or sales reasons to urge the Sony of the technology to compromise the market, or perhaps the positioning of the Korean system. Whatever the case, the Sony Z9D yesterday brought a full score for fans who are looking for black technology. It is a flat-panel TV that is completely beyond this era.
