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
65-inch Sony OLED TV A1 side
Sony OLED TV A1 continues Sony TV's design philosophy of “Slice of living†in recent years. Unlike the vertical TV with a pedestal, A1's screen and the back of the host are stabilized by a support rod, so the screen will have The slight elevation angle, placed on a TV stand that is not too high, gives a comfortable look.

Borderless design
Compared with iPhone 7 thickness
The front of Sony OLED TV A1 left us with only a screen with an ultra-narrow border, so the faith-filled SONY logo is also intended to be reduced, and the BRAVIA logo even goes 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, Sony's OLED TV A1, like the Z9D and X9300E, has a hidden backplane design, and all 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., and Sony OLED TV A1's advantage lies in carrying an independent research and development of image processing chips and a lot of quality technology.
Sony OLED TV A1 uses the same 4K HDR image processing chip X1 as Z9D and X9300E. This is Sony's current strongest image processing chip, and its overall performance is 40% higher than the previous generation X1. This chip repairs and optimizes the image signal from three aspects: 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's OLED TV A1's NTSC color gamut is 91.04%, ordinary LCD TVs can only use quantum dots in LCD backlights to achieve such color gamut performance.
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.
Motion 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. The passengers in the car can see clearly. The outline of the building across the window can also be clearly identified. This is a very difficult result for many LCD TVs.
HD proofs real shot
As can be seen from the screening of several sets of proofs, Sony OLED TV A1 is very accurate in restoring the colors, maximizing the true feelings, rich levels of detail, and control of color 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 backplane of the Sony OLED TV A1 also actually “hidden†a bass unit, which formed a 2.1-channel sound system, and had better bass performance than ordinary TVs. The audio strength should not be underestimated.
System content is gradually optimized and upgraded
As with the external design style, the operating system of the Sony OLED TV A1 is clean and simple, especially without the interference of advertisements. There is no difficulty in operation. 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 cooperated with Huadian to provide various contents including movies, television dramas, news, and variety shows. In addition, it also continued to strengthen the localization of high-quality content. Sohu Video, LeTV Sports, and QQ Music have joined the TV content camp, or Third-party applications can be installed 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 the Sony 55/65-inch A1 is 24,999 yuan/35,999 yuan respectively. It is a high-end audio-visual experience. As a decade-long effort by Sony, the Sony OLED TV A1's audio and video strengths are expected to become the flagship Z9D. A good choice. â–
D-sub Connector Contacts
A D-sub connector is a form of connector commonly found in electronic and computer systems. It consists of a D shaped metal band and two or more parallel rows of either pin contacts (male) or socket contacts (female). D-sub connector contacts can vary in size, material, current rating, length and resistance.
The most common type of connector is the crimp contact. These are assembled by inserting a stripped wire end into the cavity at the rear of the contact. The cavity is then crushed using a crimp tool, gripping the contact to the wire.
What are D-sub connector contacts used for?
The D-sub connector contacts carry the signal from the source to the destination across the D–sub connection.
Types of D-sub connector contacts
Most D-sub connectors are supplied with contacts ready in place. Contacts can be replaced if damaged or if the application of the D-sub connector is to be changed from the original design specification.
High-current, high-voltage, or co-axial inserts require larger contacts. The material of the D-sub connector contact can be changed if the robustness or quality of the connection needs to be improved.
