Strength leads the future of OLED reveal Sony A1 black technology

Judging from the trend of China's color TV market this year, it should be the year that OLED TV broke out. At the beginning of the year, Sony introduced the Sony BRAVIA A series of revolutionary products in the field of OLED television at the CES exhibition in the United States. This is Sony's latest masterpiece in the top TV field following the milestone LCD TV Z9D series launched last year. Today, the 65-inch model Sony A1 in this series took the lead to our evaluation room. How about the strength? Let's take a look!




The Sony A1 TV is equipped with the brand's exclusive screen sound field technology, which directly sounds through the screen and brings the audiovisual experience that no one television can provide in the past - "unity of sound and picture". At the same time, Sony is proud of it. As for the display effect, due to the addition of the X1 advanced image processing chip, it can not only maximize the wide viewing angle and no trailing characteristics of the OLED technology itself, but also realize more exquisite dynamic image processing. Realistic visual performance. It can be said that even if we do not talk about the index parameters, A1 is already a milestone landmark in OLED TV history.

Today our evaluation is divided into four parts, appearance, picture quality, sound quality and system, not much to say, let's take a look at the appearance of the Sony A1 TV:




With the minimalist words to describe the Sony A1 this TV is more appropriate, ultra-narrow frame and no base design allows the entire TV to see at a glance only a pure black screen, the ultimate simplicity for the A1 is more technological future. At the same time, the OLED panel adopted by the Sony A1 has two roles: display and speaker diaphragm, so the whole machine can generate sounds without using additional speakers. The Sony A1 builds a solid triangle between the support of the ultra-narrow bracket on the back and the slightly reclined screen. Although it looks very thin, but in fact, the overall weight of this TV reached an astonishing 49KG, and most of this weight will come from the back support, TV image processing chips and subwoofer and other black technology products are hidden in it .

Sony A1's screen thickness is even less than 7.8 mm, slim as an ordinary glass. At the same time thanks to the unique advantages of OLED screens such as ultra-thin, low-power, and flexible, A1's screen frame also uses a seamless bending process, which can help users extend their viewing angle and bring a better viewing experience.

Sony A1's back design is also streamlined, as always, using a hidden design, provides a simple removable backplane, after installation, the back of the bracket does not have any extra elements, the wire can also be completely hidden effect, does not seem a mess.

When you remove the bezel, you can see the internal interface and wiring details.

We can see that the interface provided by the Sony A1 is very complete, with TV antenna, HDMI, USB, AV video input and network interface behind the TV.

Even Xiao Bian also found that the side of Sony A1 bracket can also be disassembled, hiding another USB interface. Details can better see Sony's ingenuity.

The TV key is located on the side of the stand.

At the same time, in the upper half of the stand, we can see the Sony A1's low range, which is only a sound supplement, not the main speaker of the TV.

The remote control still uses the Sony's traditional design. The multi-key operation makes it quick and easy to use. It is easier for old users to get started, and feels good in the hand, without any learning cost.

Here's the finished part of the Sony A1. If you want to learn more about picture quality, please pay attention to our latest review articles.

Sony A1 quality & decoding analysis analysis
The core function of TV is "watching", so the picture quality is naturally the most important thing. The quality of the picture directly affects the user's viewing experience. Sony A1 uses an OLED screen known as the "future display technology." How can we present the perfect display effect of an OLED panel? It is also possible to cooperate with Sony's self-developed image processing chip and many image quality technologies.




The Sony A1 uses the same 4K HDR image processing chip X1 as the Z9D series, which is 1.4 times more powerful than the original X1 chip. It carries out unprecedented precision repairs and optimizations in terms of color, sharpness, and HDR, resulting in better picture quality performance. This technology is mainly composed of HDR dynamic item-by-item remodeling technology, dual image database, and 4K HDR 14-bit smooth gradual change.




The workflow of the Sony 4K image processing chip is very complicated. After the signal source is input, it will enter the signal analyzer and the signal processor synchronously. The analyzer will detect and analyze the picture based on the object and output the result to the signal processor. Partial correction and optimization of the original signal. After the signal processor delivers the signal to the panel driver, the panel feedback is also sent back to the processor, optimized and sent to the driver display again.




After the professional instrument BM-7 test, the score of the Sony A1 in both the bright field and the black field is obviously higher than most HDR models on the market, and the brightness is very excellent. Measured 92.21% of the measured NTSC color gamut (values ​​for reference, different device test values ​​will be different, of course, still rely on the actual quality of expression to speak), significantly higher than about 75% of the ordinary television gamut As a result, you can see a much wider range of green and red areas in the gamut diagram.




Many products on the market today are overly colorful and even distorted due to excessive attention to color saturation. What Sony has been pursuing all the time is to achieve the same quality as the actual environment seen by the naked eye. The images displayed after optimization of the Sony X1 advanced chip are colorful and realistic without loss of quality. It is absolutely amazing.

Let's take a look at a set of Sony A1 TV photos:

The overall details are outstanding, the brightness of the picture is greatly enhanced, the bright part is brighter, and the dark part is more profound in retaining details.

When watching TV, the screen is often in motion, so dynamic clarity is one of the important criteria for measuring the quality of television. We will restore the TV to the factory settings, play the dynamic test film source in the default mode, view the dynamic resolution, close-up view, it is also difficult to identify the smear phenomenon, even the high-speed train in the shadow of the train can be very clear see.

Summary: This Sony A1 TV TV excels in picture quality and can perfectly display every detail of the picture. Relying on Sony's years of experience in color tuning, A1 achieves such a high color gamut coverage. , also able to show the true and natural colors. The screens seen from all angles are just as good-looking. There are no signs of astigmatism or light leakage. The phenomenon of distorted screens and colorful images are accurate. This is very commendable. It can be said that it has achieved excellent image quality.

Sony A1 sound quality measurement analysis:

Speaking of the Sony A1's audio part, it is also a strong black technology that does not lose to the picture quality part at all. Xiao Bian had to say that Soda Dafa was a real muffled voice this time. The A1 series is the world’s first large-screen TV that can use the screen to make sounds. Let's start with a technical look at this magical screen-speaking "screen sound" technology. According to official sources, Sony has developed the Acoustic Surface technology (screen sound field technology) with the advantage of an OLED backlight-less structure that allows the screen itself to directly emit sound. And this way of vocalization can make its sound and picture combine perfectly, and achieve more extensive "sound and picture synchronization" effect.




The above may be too mysterious, let's briefly talk about the principle of this technology. As you may know, the sound is generated by vibration. The Sony A1 also uses the property that sound waves are vibrations. Two vibrating units are placed behind the left and right sides of the screen. When the drive units in different positions work, A1 will also Sounds come out of different places on the screen. If a student can touch the screen of A1, he can feel the special vibration more directly. Xiao Bian believes that at that moment you could not help but shout "black technology"!




Visually, this new sound structure allows A1 to design a separate speaker system without sacrificing the width of the frame or the thickness of the body (such a system is always difficult to balance in terms of sound performance, size, and price), but also The elimination of the recent popular split TVs requires the additional visual and installation problems associated with the "sound bar". Even wall-mounting can be truly integrated and there is no need for redundancy.

From the standpoint of sound performance, due to the presence of a special Acoustic Surface technology, the sound source of the sound can be mapped to the point on the screen. For the first time in history, the sound and picture of “where do you hear?” is truly achieved. The synchronization effect further enhances the sense of presence when watching TV. Coupled with Sony OLED 4K HDR exclusive image processing chip X1 advanced version, the picture is impeccable, and the sound is closely followed. At this time, watching a nature documentary or “China on the tip of the tongue”, you can feel the wind and leaves sway around and the chef cooks the food in front of you. The real “ultimate audio and video enjoyment” is not too It!




In order to take care of the low-frequency harmonic loss caused by the relatively hard OLED screen's direct vibration, Sony also placed a bass unit on the back of the A1 to form a 2.1-channel, enhanced low-frequency response in the playback of jazz scene or American "gun car. When the ball was large, it was more real and shocking. It is also beautiful to enjoy listening to music.

Summary: Sony A1 screen sounded very dark technology, surprised to actually be able to do such a high sound quality, at home will be able to enjoy the natural and impact of lively images, unique shock effects and true sound and picture Oneness.
