The sound is emitted from the screen! Sony OLED TV A1 Acoustic Surface released

Sony recently launched a new OLED TV as part of its BRAVIA series. This model incorporates the popular 4K technology and supports Dolby HDR video decoding, offering an immersive viewing experience. From the outside, it resembles a large flat panel, with a unique design that eliminates the traditional base. Instead, it features a frame-like back support, giving it a sleek and modern appearance. ![Sony OLED TV](http://i.bosscdn.com/blog/11/36/59/tjs6fx2xqybf3d3n.jpg) One of the standout features of this TV is Sony’s Acoustic Surface technology. Unlike conventional speakers, this innovation uses the screen itself to produce sound, eliminating the need for separate audio units. This not only saves internal space but also allows the TV to fully utilize the advantages of OLED technology, such as ultra-thin design and superior contrast. ![Acoustic Surface Technology](http://i.bosscdn.com/blog/11/39/40/ok3nznnnu2d8868n.jpg) Thanks to the OLED panel, this 65-inch "big glass" is incredibly thin—just 7.8mm thick, which is similar to the thickness of a smartphone. The slim profile adds to its elegance and makes it a perfect fit for modern living rooms. ![OLED Design](http://i.bosscdn.com/blog/11/39/40/n2cw2tnbif10ydct.jpg) In terms of pricing, the 65-inch A1 model is available for 35,999 yuan, while the 55-inch version is priced at 24,999 yuan. These prices reflect the high-end nature of the product, targeting consumers who value both performance and design.
