True minimalist design This evaluation machine is a 65-inch version, because there is no TV base bracket, placed on the table and the desktop (SONY's logo in the lower left corner). Although it is also possible to use a rack to fix it on the wall, the overall effect is not as good as on a TV cabinet. Sony OLED TV 65A1 positive Sony OLED TV 65A1 side A1 continues Sony TV's design philosophy of “Slice of living†in recent years. Unlike the vertical TV with a pedestal, A1's screen is stable with the back of the mainframe, so the screen will be slightly The elevation angle, placed on a not too high TV cabinet, can bring about a comfortable look and feel. SONY logo in the lower left corner Borderless design Compared with iPhone 7 thickness The front of A1 left us with a screen with an ultra-narrow border, and the SONY logo full of faith was also intended to be reduced. The BRAVIA logo even went to the back of the TV. In addition, compared to LED LCD TVs, OLED TV because of its simple structure has the advantage of innate thin, but Sony this OLED TV did not pursue the limits of thinness, thickness and iPhone7 almost, if the body is thinner, I am afraid it will be Worry about its strength. TV back Remove the backplane to see the interface section The entire television back panel glass design, the host back panel is a cloth material, the mirror and the fabric put together very visual impact. In addition, the A1 adopts a hidden backplane design similar to the Z9D and X9300E, and various cables can be completely hidden. Interface design Side USB interface Interface is located at the bottom of the bracket, including antenna, network, optical audio output, AV input, 4 HDMI, 2 USB, etc. For ease of use, the side is also very close to providing a USB interface, there is also a small Power switch key. remote control The remote control continues Sony TV's traditional design and exquisite workmanship. However, due to the large number of buttons, it needs to adapt to a certain period of time before it can be completely used. OLED has advantages but cannot do without Sony's excellent image quality tuning capability There are many inherent advantages of OLED TV, such as contrast, black field performance, color gamut, response speed, viewing angle, etc., while the advantage of Sony A1 lies in its own research and development of image processing chips and a lot of picture quality technology. Sony A1 uses the same 4K HDR image processing chip X1 advanced version as Z9D and X9300E. This is Sony's strongest image quality processing chip, and the overall performance is 40% higher than the previous generation X1. This chip repairs and optimizes the image signal from the aspects of color, sharpness, and HDR**. The specific theory does not speak directly to the effect. NTSC color gamut 91.04% The use of professional instruments BM-7 test results show that Sony A1's NTSC color gamut is 91.04%, ordinary LCD TVs can only achieve the color gamut performance by applying quantum dots to LCD backlights. Pure black scene When the black screen is presented, the test instrument has completely failed to read the brightness information. At this time, the OLED panel does not emit light, and a pure black screen is presented. HDR film real shot X1 Advanced Edition is equipped with “HDR dynamic item-by-item reshaping technologyâ€. This technology optimizes the algorithm to make the details of the light and shade of the picture more realistic. Although the OLED is slightly inferior in brightness to the LCD, from the perspective of test data, HDR is playing. The maximum brightness of the film is also doubled, showing the strength of the X1 advanced chip. Dynamic picture With its superiority in response speed, OLED TVs do not have the phenomenon of smearing, afterimages, etc., which are common to LCD TVs in the performance of moving pictures. This is perfectly represented on the Sony A1. The high-speed trains are smooth and natural, and the passengers in the car can see clearly. In addition, the outline of the building across the window can be clearly distinguished. This is a result that many LCD TVs are difficult to achieve. HD proofs real shot As can be seen from the screening of several sets of proofs, A1 is very accurate in the restoration of colors, and it restores the true feelings to the utmost. The level of detail is rich, and control of colors is in place. The combination of audio and video is an unprecedented experience In previous TV evaluations, the sound quality generally did not take up too much space, but the Sony A1 did not have direct audio, so that the sound of the screen was indeed unexpected. This "black technology" is necessary to say a few more. According to information provided by Sony's official, A1 developed the Acoustic Surface technology (screen sound field technology) by utilizing the advantages of OLED without backlighting. It utilizes the characteristics of sonic vibration, placing two drivers on the left and right sides of the screen, and letting the screen pass through it. Vibrating sound, which means that the entire screen of the TV is equivalent to a speaker. Left and right sides of the screen drive Drive details The most amazing thing about this technology is that the sound source can correspond to the screen and achieve the effect of audio and video synchronization. That means the sound source can change with the change of the image. This is an unprecedented audiovisual experience. Use a movie to feel the effect of the next picture. Firstly, the artillery shell's shuttle sound is obviously shifted from the right side of the screen to the left side, and when different characters speak, the sound will be directly sent out from his/her mouth. It feels like the real person is standing there talking, the sense of space of the sound, The sense of three-dimensionality is very strong. Bass unit on the back of the host In addition, the A1's backplane actually “hidden†a bass unit and formed a 2.1-channel sound system. Compared with ordinary TVs, it has better bass performance and audio strength. System content is gradually optimized and upgraded Like the external design style, the operating system of the A1 is clean and simple, especially if there is no interference from advertisements. There is no difficulty in getting started. At present, the system has been upgraded to Android version 7.0, and the fluency of the system is worthy of recognition. In terms of content resources, Sony cooperates with Huadian to provide various contents including movies, television dramas, news, and variety shows. In addition, it also continuously strengthens the localization of high-quality content. Sohu Video, LeTV Sports, and QQ Music have joined the television content camp, or You can install third-party applications to extend content. Experience summary The emergence of the Sony A1 has injected a powerful boost to the fast-growing OLED TV market. It not only inherited the rich image quality technology accumulated in the LCD TV field, but also fully utilized the features of the OLED to bring a new audiovisual experience. Full release of the potential of OLED, the current industry may only have such strength of Sony. The price of Sony's 55/65-inch A1 is 24,999 yuan/35,999 yuan. It was quite unexpected to just see this price, and although it is still expensive, after Sony's "processing", A1's audio and video strength has reached a super high level. Beyond the flagship Z9D, another great choice.

The most worthwhile to buy OLED TV Sony A1 TV evaluation
OLED is the most promising next-generation display technology. As early as 2007, Sony introduced an 11-inch OLED TV XEL-1. However, because OLED technology is not mature enough, it is not mass-produced. After ten years of technology precipitation, Sony finally brought the OLED TV back to us and launched the A1 series of new products covering 55/65/77 inch** size segments. In addition to the deep quality of the Sony A1 into the OLED, but also brought a "sound and picture" black technology, presumably a lot of people are full of expectations for this TV.
