This system is to begin mass production in 2025.
Sony Electronics has announced it has developed a new display system incorporating an independent drive RGB LED with a high-density LED backlight that can individually control three primary colors — R (red), G (green), and B (blue) [RGB] — and that is suitable for large screens. This panel allows each RGB color to emit light independently, resulting in high color purity and the ability to reproduce images with a vibrant, wide color gamut. Additionally, the display system is equipped with Sony’s proprietary advanced backlight control technology, designed to maximize the panel’s characteristics. This backlight control technology enables faithful reproduction of delicate hues and subtle gradations of light across every corner of the display, even on large screens. In cinematic works such as films, the ability to convey narrative expression relies significantly on the subtleties of color and black representation, as well as the gradation of light. This system enhances these elements to provide image quality that faithfully reflects the creator’s intent and is suitable for both film production and home viewing.
The display system has been developed leveraging unique experiences and technical expertise gained from Sony’s historical support of creators’ activities through professional monitors used for color grading in video production and BRAVIA utilized as reference monitors. This system is to begin mass production in 2025, aiming to expand its integration into consumer televisions and displays for content creation.
Sony Electronics developed the world’s first LCD television with a full-array RGB LED backlight in 2004. Since then, Sony has continuously worked to improve the precision of backlight control, gaining a deep understanding of the characteristics of LED elements. In the development of this display system, Sony’s unique backlight control technology contributes to maximizing the panel’s performance.
Sony is participating in joint development of control processors with MediaTek Inc., its long-term strategic partner, and a company with a proven track record in developing and supplying SoCs (Pentonic) for smart TVs. Sony is also working on the development of the LED drive IC together with ROHM Co., Ltd., and the LED together with Sanan Optoelectronics Co., Ltd. These partners support Sony’s direction for next-generation displays.
