OFweek Smart Home Network News: Where is the future of flat-panel TVs? This can be said to be the biggest doubt for all home appliance manufacturers in 10 years.
10 years ago, LCD TVs and plasma TVs were indispensable. LCD has a short board with response time and viewing angle, plasma has the power consumption and burn screen weaknesses, who can find the direction of the next generation of flat-panel TVs, who can become the overlord in the next round of competition. All home appliance manufacturers want to copy CRT era Sony's counterattack against Terry.
But again, Sony has never stopped its own progress.
10 years ago Sony named the world's first OLED TV XEL-1.
Ten years later, Sony named its first 4K HDR OLED TV as A1. In Sony's naming philosophy, if a product does not have a significant breakthrough and cannot be written into history in the future, it is not worth mentioning No. 1.
Return to OLED Sony will open the wheel of OLED's fate
When Sony officially released the 4K HDR OLED TV A1 earlier this year, many media exclaimed that Sony had returned to the OLED market. In fact, Sony spent more than 10 years researching OLEDs and XEL-1, and after 10 years of XEL-1 release, continued to develop and improve OLED display technology.
Today, the longest lifetime and highest color accuracy of OLEDs in the display area are maintained by the TRIMASTER EL series monitors based on Sony's OLED panels. This shows that Sony has precipitated in OLEDs.
Rethinking 10 years ago, in the ups and downs of the flat-panel TV battle, Sony took the lead to come up with an 11-inch OLED TV XEL-1 with a resolution of only 960 x 540. In the same period competitors Mitsubishi/NEC's laser TV, Canon SED field Led TV failed to appear on schedule. Afterwards, the Korean wave hit, Mitsubishi/NEC laser TV stalled slowly, and the Canon SED eventually failed to go public.
Now, the protagonist of this article Sony BRAVIA A1 is returning with OLED, which is like a fast-turnaround carbine for the consumer market. As the king of OLED professional fields, what kind of technology will Sony OLED A1 use to knock on the living room door, and Z9D go hand in hand? The Sony OLED A1 experience is hereby offered.
Aesthetic design a perfect floating film
How to get the TV to stand up is a problem that heavy old CRTs have never considered. In the Tablet Age, in order to ensure that the TV does not directly shoot on the floor, I do not know how to kill many designers’ brain cells. This is only the beginning. The ultimate goal of TV is to float the film, that is, there is no extra content except the screen.
So the first thing the Sony OLED A1 did on stage was to get rid of the TV stand so that the factors that interfered with the picture dropped to a minimum. As you can see from the picture below, yes, the picture stands up.
Sony OLED A1 does not have a traditional base, so this TV stands up is a special design of the bracket. This set of brackets clings to the bracket from the package, so installing the Sony A1 at home only takes three steps: unpacking, unfolding the bracket, and energizing the TV.
However, if you want to quickly install the Sony OLED A1, the cooperation of two or more people is necessary. Because a counterweight base needs to be installed at the end of the TV bracket, one person needs to support the A1 panel so that there is a gap between the bracket and the ground, so that another person can install the base and fix its support frame. However, please note that the base is really heavy, and the texture is very strong. Even editors who are often active in the editorial department need two hands to raise the base.
To solve the TV standing problem, you will find that this TV and the TV in the impression are almost all the same. The design without any speakers makes the Sony A1 look like a mirror. With the Acoustic Surface (screen sound field technology), direct screen sound, this even the design of the back of the common TV arc is also omitted, the display panel side thickness of only 7.8mm.
The front Sony Logo has been deliberately narrowed down to the bottom left of the screen. If you turn off the indicator directly below, and add the ultra-narrow frame design of the screen itself, you can feel that the engineers of Sony R&D A1 have hoped to highlight the picture from the beginning. intention.
After OLED's peculiar figure was displayed, Sony OLED A1 moved all interfaces under the support, including 2 USB2.0, 1 USB3.0, 1 audio output interface, 4 HDMI interfaces, and 1 video. Audio input interface, 1 digital audio output interface, 1 RJ45 interface, 1 wired/antenna interface and 1 remote control expansion interface.
Sony also left enough cable clips under the interface. Unlike the Z9D, which requires wiring, all the cables can be straight and straight, and the wiring is very refreshing.
When all the wiring work is completed, you only need to fit the back cover of the fabric with the bracket. Even if viewed from the back of the Sony OLED A1, the TV still maintains a very strong integrity. What's more important is that the fabric backboard cleverly covers all cables and connectors without leaving any openings.
The combination of sound and picture mirror to restore the real scene
How can you make your TV look pleasing? On this topic will be endless discussions, but it cannot be denied that the advantages of OLED characteristics, so that the LCD on the black level, contrast, vision, color gamut, uniformity and even power consumption confidence disappeared. If you are interested in the Z9D, then congratulations, Sony OLED A1 can also make you excited, and even easier to have your hands on your wallet.
Experts talk about HDR first. Due to practicality and power consumption control, the brightness of current OLED TVs is generally not high. Ironically, HDR first requires televisions to have a higher level of brightness first, so as to support the dynamic range of the entire picture and obtain more details. Show. In addition, the HDR content itself follows BT. The 2020 color gamut standard shows that the color range does not have HDR TVs to match. For example, we have tried to put HDR content on ordinary TVs that do not have HDR. Ordinary TVs can only be exposed according to shadows, and the screen is simply unattractive.
OLED is born with excellent performance in contrast and color gamut, and it can easily display the luster of the screen. The performance of the Sony BRAVIA A1 is the same. We first compared the Sony 4K HDR demo "Camp" with the 4K non-HDR version of "Camp" on the Sony OLED A1. The brightness is set to the highest, and HDR is a gimmick.

In fact, the Sony 4K HDR Processor X1 Extreme (Advanced version of the 4K HDR image processing chip X1) provided by the Sony OLED A1 plays a major role in this. Sony's years of hard work and dominance in OLED professional fields are not casual. For example, the newly-added HDR dynamic image-by-image reshaping technology can analyze the color and texture of each frame of an image on the playback screen one by one, and on objects. The color and contrast are corrected to optimize the global picture.
Because of this, Sony BRAVIA A1 displayed a strong three-dimensional image in the "Hamp" HDR version, such as sparkling arcs, deeper skies, plus OLED's further control of highlight details. There is even an illusion that the screen will breathe fresh air from the lake.
4K HDR image processing chip X1 advanced version is not only a unique stunt, the second stroke 4K HDR 14bit smooth gradient can use the chip's own 14bit signal processing capabilities, through frame-by-frame analysis, to optimize the color scale, let 8bit or 10bit film The color of the source becomes more abundant and overly smooth.
OLED captures the details in a bright picture, and the feature of no backlight is much easier than LCD to be "blacker than black". However, the transition from dark gray to total darkness is still a continuous process. We were worried whether the black spot on the Sony OLED A1 would be killed by a stick. So we got the HDR version of the Las Vegas demo and not The HDR version of the fireworks demonstration film was observed at a resolution of 3840 x 2160.
The surprising thing in the fireworks demonstration is that Sony OLED A1 is rich in details from gray to black. If it is not the 4K logo hint in the upper right corner, it would even make people think that this is an HDR demo proof. It can be clearly seen from the screen shot that after the fireworks illuminate the sky, the light is thrown into the cloud and reflected by the layers. The layering of the cloud has become stereoscopic with the help of high resolution and smooth gradient technology.
Sony OLED A1 uses Las Vegas's late-night demonstration to tell what is really black, pixel-level backlight control makes the picture become exceptionally smooth and neat, the black in the sky is really black, there will not be those annoying on the LCD The backlight disturbs and the contrast is extremely strong.
If the light sensor of the Sony A1 OLED is turned off, the brightness is adjusted to the highest level, and the Sony A1 is not too dazzling in the indoor environment that is almost completely dark at night. In the daylight environment, the picture is clearly visible without any pressure. It is enough to prove that Sony A1 did not exert too much force on the brightness of OLED, but it was just right.
The practice of knowing the truth and jumping out of DEMO on the quality of the image is not a suspect. Using the XBOX One S as a Blu-ray player, you can insert various types of Blu-ray discs, including Ultra HD, or Forza Horizon 3 that supports HDR output, and Final Fantasy 15 that has nothing to do with various new technologies. †One by one, the Sony OLED A1 was bombarded.
It should be noted that the Sony OLED A1's HDMI interface, only the HDMI 2 and HDMI 3 interfaces can fully support 4K UHD (60Hz), HDR movies and game screen output, or Sony BRAVIA A1 can not achieve the best results, this The point is somewhat puzzling. Usually users will use HDMI 1 subconsciously. Therefore, when connecting Sony BRAVIA A1, please connect the main device to HDMI 2 or HDMI 3.
Left connection is HDMI 2 or HDMI 3, XBOX One S can properly turn on 4K UHD, right is connected to HDMI 1 or HDMI 4, and XBOX One S cannot turn on 4K UHD
Sony A1's tuning is in place, providing up to 12 modes in the image settings is a choice, and a simple and concise description of the actual use of this mode. One of the most impressive is still the professional film model. According to engineers, the color palette of the professional film model is also closest to the film source itself.
In Nolan's "Pirates of Dream Space", the contrast between the professional movie mode and the standard mode is particularly obvious. The strong access of the dual image database image processing technology in the standard mode will treat the noise in the film and film very cleanly. Coupled with the adjustment of color temperature, "Pirates of Dream Space" has a taste of online high-definition movies. However, in the professional movie mode, the film taste of “Pirates of Dreams†was completely preserved, and the dual image database image processing technology did not interfere too much with the film.
This situation also appears in the "Star Trek", the professional film mode blessing so that the outer planet Nolan eyes texture full, at the same time OLED brings a strong contrast and it is easy to make the scene feel like it, especially in In the IMAX scene, the screen fills up the entire TV screen.
The night scenes of “Secret Agents†were also performed by the Sony OLED A1. In the scenes pursued in the night, the characters in the darkness were not integrated into the night and the screen was sufficiently detailed.
Also in the "Miyakojima" Ultra HD version, the details of the highlights on the screen are more easily handled by the Sony OLED A1, and the most impressive is that after the strong contrast between the bright red hibiscus and the dark parts of the background, the red petals are still not overflowing sense. The high contrast of the Sony OLED A1 leaves room for imagination in the dark part without loss of detail, and the light, shadows and lines on the petals are clearly displayed. To know that this is a video rather than a still picture, the advanced version of the Sony OLED A1's 4K HDR image processing chip X1 played a large role.
The sound and picture combination screen is a speaker
The seamless design of the Sony OLED A1 and the ground is the first to get rid of the Soundbar created in the flat-panel TV era. However, it is really not a problem for Sony OLED A1. Sony's Acoustic Surface (black screen sound technology) did two things in one fell swoop with the use of OLEDs without back-light structural features. The first was to get rid of the Soundbar, and the second was to kill random speakers.
You are not mistaken, Sony OLED A1 eliminates the vocal structure on traditional TVs and instead uses the screen sound field technology to sound through the OLED screen itself. Such a scenario was placed in the home TV market a year ago and was never imagined. .
The drivers that control the sound of the Sony OLED A1 OLED screen are located on the left and right sides of the screen, respectively, and two are grouped to make the OLED sound through vibration. This is one of the places that Sony OLED A1 is most proud of. This is the first time in the history of the planet that it has reached the unity of sound and picture. When we watched the A1 test video provided by Sony, we could clearly hear the sound of birdies and train siren being transmitted from left to right. The synchronization and positioning of the sound and vocal subject screens became clear.
However, the sound environment of the daily playback screen is more complicated, such as the vocal dialogue, background music, or street noise. The concerto in a variety of musical instruments to play together can test the Sony OLED A1's actual ability to resolve the sound. In a 4K HDR piano concerto, the interweaving of piano, cello, and violin did not make the sound of the instruments mingle. Instead, the entire scene of the concert could be fully expressed. In addition, the high contrast between HDR and OLED itself made it appear that The music, presence and the screen are spewing out, which is exactly what the Sony OLED A1 flagship model can express.
In addition to the two left and right drives on the screen, the stand itself is subtly designed as a subwoofer. Sony OLED A1 can be understood as a set of home theater kits without additional accessories. It can be connected to the video source via USB and can be configured without any configuration. A film, concert, chanting. Sony OLED A1 sound across the low-frequency, intermediate frequency, high-frequency words, vocals, birds, waves, urban noise, classical music on the Sony OLED A1 can have a good performance.
As a game powder, of course, we have to test the performance of this Sony OLED A1 game sound performance, of course, its performance has completely exceeded my imagination, such as in the "Final Fantasy 15" game, Suzuki Dayang slightly childish The vocalization of the youngsters and the magnificent music brought by Masako Shimomura can quickly make people silent in the sound of the game.
Concluding remarks: The late bloomer but in one step When we watched the movie on Sony OLED A1 with the audio and video players, we lamented that the details of the screen were still rich in detail, but they invariably praised the color tuning of the professional movie model in place. . The new frame design concept, Acoustic Surface (screen sound field technology), ultra-thin panel, HDR, OLED, all black technology is integrated into a TV, the flagship model's king style through the Sony OLED A1 blowing.
The appearance of Sony OLED A1 not only proves Sony's strength in the OLED field, it even provides a complete and quite outstanding solution from the image to the sound quality. Sony OLED A1 further squeezes OLED paintings through the advanced version of 4K HDR image processing chip X1. Quality, and screen sound field technology almost subverted people's doubt that the TV itself could no longer produce a good voice after the CRT was eliminated. If the Z9D is the benchmark for LCD TVs in this era, then the Sony BRAVIA A1, which was the start of the same door, is the innovator. It once again proves the advanced nature of OLED and Sony's status as a company full of black technology.
It is undeniable that Sony OLED A1 is one step behind our imagination, but it is still in one step, helping us open the door to the new world.
