Sony Develops Next-Generation Display System with Proprietary Signal Processing Technology for Individual RGB Control of High-Density LED Backlights

Sony Electronics 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.

The display system processes signal at a high speed and with high precision at a high bitrate of 96 bits. This not only allows the simultaneous expression of deep blacks and brilliant whites, but also enables the delicate representation of differences in brightness and darkness in scenes with many intermediate colors. This new system can achieve what is challenging for existing OLED panels: the expression of colors with moderate brightness and saturation. Moreover, high bit-rate signal processing helps deliver a wide viewing angle by precise gradation control, minimizing color shift and brightness variation when content is viewed at a slant on a large screen.
