200 tries and improvements! Explore the story behind Sony's first OLED TV A1

It has been a while since Sony’s first large-size OLED TV A1 series was listed. What kind of transcripts did the products of the entire television industry astounded at the beginning of this listing? Statistics from the latest authoritative organizations show that the Sony OLED TV A1 series that was first released in the Chinese market this year has received more than expected market acclaim. Within less than half a year after launch, it has occupied the top position in OLED sales, and the market share. It is more than 30%. To know that the overall demand for the Chinese color TV market has dropped by 9%, and Sony has increased by 30%, and we have to once again marvel at Sony's strong market appeal.

At the same time, A1 also won a lot of world-famous and very authoritative awards during this period, including the German Red Dot Design Award, which is called the "Oscar" in the design sector. And with the official launch of the new 77-inch A1, Sony's OLED product line has now formed a complete configuration of 55/65/77 inches. What are the few stories behind the success of the A1 series? Just last week, we were invited to visit Sony TV's headquarters in Tokyo, Japan. Through in-depth communication with product engineers, we also have a more in-depth understanding of this product.

Guided by technological innovation and user needs

In many previous interviews, Sony executives repeatedly mentioned the most common words: To make products from the perspective of truly satisfying the needs of users, as long as it is a technology that is beneficial to users, Sony will make every effort to bring everyone the best. Good experience. At this time, the introduction of OLED TVs is also the result of full justification and market research. As Gaoqiao Yang, chairman and CEO of Sony (China) stated, Sony did not stop developing OLED products in the past decade. After a decade of hard work, technical problems have been solved and OLED panels can be mass-produced and applied to Sony's products. Sony is only able to introduce the A1 series to the market when it has the ability to introduce OLED TVs that exceed the details of LCD display in the black and dark parts.



â–² Sony's 77-inch A1 vs. Sony's first OLED TV XEL-1 ten years ago
As early as ten years ago, Sony was the first manufacturer to mass-produce OLED TVs and launched the first 11-inch OLED TV XEL-1. Extreme ultra-thin design and outstanding picture quality caused a great sensation in the industry. Afterwards, Sony has not stopped the development of OLED screens. In 2012, Sony introduced the world's first medical color display PVM-2551MD using an OLED panel. It adopts the unique “Super Top Emission” structure OLED panel plus advanced processors. With the support of the display, the picture has a pure dark black, excellent motion response and faithful color reproduction; in 2015, it also introduced the world's first 4K OLED display BVM-X300, which is equipped with the top-level ITU R BT 2020 Ultra-wide color gamut, and also supports ultra-wide dynamic range mode.
The A1 series released at the beginning of this year has achieved a major breakthrough in product quality and sound effects. The Z9D is equipped with an advanced version of the X1 image processing chip on the OLED; in terms of sound effects, the screen's sound field technology is used by taking advantage of OLED's inherent advantages. The cooperation of these two technologies has enabled the A1 series to achieve the "unity of sound and picture" that other brands can't imitate. This is regarded as the best OLED TV recognized by the industry. At the same time, Sony believes that Chinese consumers are more interested in large-size TVs, and it is difficult for them to meet the needs of their larger home scenes. This part of high-end consumers is more eager for larger-size TVs, and 75-77 inches is the most suitable for this group. The size of the high-end people's home environment, this new launch of 77吋A1, is precisely the desire to provide multi-dimensional choices for different scenarios for consumers.

The screen sounds "black technology" 200 attempts and improvements are only the best

In addition to outstanding performance in the aspect of picture quality, Sony A1 is also meticulously crafted in terms of product design and sound effects. When talking about audio performance, Mr. Yoshioka Shigeshi, Sony Visual Products’s sound engineer, mentioned that as early as a few decades ago, Sony had already begun to study the technical principles of the screen sound field, and after many years of repeated testing, the technology has been Very mature. The technology was first applied to the XEL-1, the world's first OLED TV, released by Sony 10 years ago.

The latest A1 TV is based on the previous technology, after more than 200 attempts and improvements, finally achieved the screen sound field technology through the screen vibration sound, and restore the most truly shocking sound effects.

In the process of technology research and development, he talked about three main difficulties: First, the vibration of the sound may cause the screen to shake, and the most significant one is the audio vibration of the bass; secondly, the problem of sound quality, there will be some problems in the sound of the glass, Sony optimizes by changing the audio characteristics and eliminating reverberation. In addition, the most important screen vibrations, durability and stability are factors that need to be fully considered. In order to ensure the sound quality and stability of A1, Sony also adjusted the sound vibrator from a single vibrator to a two-in-one design. At the same time, to prevent the TV picture from being affected, Sony mainly passed heat sinks, multi-point contacts, and DSPs. Signal processor to enhance control.

The characteristics of OLED display technology also form the basis for Sony's development of the screen sound field technology. The real technical difficulty lies in how to achieve the "audio and video unity" visual and audio effects. At present, only Sony has the strength to commercialize this technology. At the same time, through some technical optimizations, Sony can bring consumers more pure and natural sound enjoyment.

Inspiration and creative craftsmanship

Sony A1 TV is also unique in product design, which also made it win the German Red Dot Design Award this year. The review committee gave the following comments: “Based on a groundbreaking integration idea, this 4K OLED TV has With this impressive and unique design, we believe that its main innovation is that almost all elements, including backplanes, are perfectly integrated into the overall design concept. The simple and delicate aesthetic works, there is no visible wires. To appreciate this TV from any angle, it always complements the surrounding environment."

Sony product designer Yokoyoshi Yokota talked about the design process of the product. In order to better display, he also took out his design manuscript. We can also see how the product was designed step by step. In expounding the design concept, Yokota Yoshiaki said that whether it is the first Sony LCD TV, or the new A1 this year, Sony hopes that the product can become an entrance to the real world. The superior picture performance of the A1 series TV is very much in line with the concept of single board design, that is, a picture can present a world without any need for extra things.

The biggest problem encountered in the design process is the sound processing. Because A1 needs to be placed directly on the desktop or on the ground, the reflection principle of the traditional TV sound from the bottom up will no longer work, and it is also benefiting from the newly developed “screen sound field technology” to enable this design to be realized. Another major difficulty is the self-luminous nature of OLEDs: Larger power supply circuit boards and high-calorie emissions will also increase the thickness of the screen while affecting the quality of the picture. Eventually, it will be possible to place components such as circuit boards and subwoofers. The design inside the bracket is cleverly solved.

In addition, stability is also a very important issue for very thin large-screen TVs, especially the newly launched 77吋A1. In order to avoid and solve this kind of problem, Sony has improved the stability of the picture through the sound unit bracket behind the screen, achieving multiple functions in terms of functionality, aesthetics, and reliability. It can be said that such design and breakthrough are unprecedented, and positive market feedback is enough to prove this.

It is these small and small trivial things that are constantly accumulating that finally contributed to such an excellent TV. Sony’s spirit of excellence is not exactly what other brands should learn.

Miniature Slip Ring

What is a miniature slip ring? Miniature slip rings are rotary electrical connectors that allow power and data to be transferred between a stationary and rotating structure. They are often used in medical, military, and aerospace applications where size and weight are critical factors.


A miniature slip ring typically consists of two parts: a stationary housing and a rotating contact assembly. The contact assembly contains the brushes that make electrical contact with the rotating structure, as well as the rings that conduct current or data.


The housing can be made from any number of materials, including metals, plastics, and composites. It is typically designed to be as small and lightweight as possible while still providing adequate strength and durability.


The contact assembly is made from precious metals such as gold or silver in order to provide good electrical conductivity.

Technology improves with the continuous development of precision machinery. The more sophisticated the equipment, the smaller the volume will be. And the space that can be accommodated for installing the slip ring is also very small. The key parts of some equipment are quite a district. Especially in the high-end military, aerospace and aviation fields. 360-degree rotation is required to transmit current and signals. And the installation space is greatly reduced. It is to make the equipment work more smoothly. Therefore, it is necessary to design the slip ring to be small and exquisite. Otherwise, it won't meet the needs of the installation.

At the same time, we have moved with the continuous development of science and technology. Various high-end precision instruments have been developed. It requires the slip ring to transmit the current amount of general power. Also often undertake the transmission of weak electrical signals and various weak signals. The transmission medium is wider, and the number of loops of the slip ring is increasing.
