Sony launches new display system that combines RGB LED and LCD panel technology

On March 14, Sony announced that it had successfully developed a unique new display system. The system innovatively uses RGB LEDs to replace traditional Mini LEDs as backlights, while still integrating them with common LCD panels. Sony revealed that this display system will officially start mass production in 2025, and plans to widely use it in the fields of consumer TV and displays for content creation, striving to provide users with a more excellent visual experience.
Sony said that the new display system uses its unique signal processing technology to achieve independent RGB control for high-density LED backlights, and has a series of significant advantages:

1. Ultra-wide color gamut performance with independently driven RGB LEDs
   Compared with traditional Mini LED screens, RGB LEDs show greater potential in color rendering and can cover a wider color space. Sony claims that the display system has a representation rate of 99% in the DCI-P3 color space and 90% in the BT.2020 color space. In addition, the color and brightness of the LED can be flexibly adjusted according to the specific content displayed on the screen, which allows even the most subtle and subtle colors to be perfectly presented accurately and without error.
2. Relying on the latest backlight control technology to create unique high image quality
   Combining independently driven RGB LEDs with Sony's proprietary backlight control technology can comprehensively and fully optimize the wide color gamut performance of the entire screen panel. The system has the function of dynamically accurately allocating the best power to each RGB channel based on specific scenarios. Not only that, the peak brightness of this panel exceeded 4000 cd/㎡, and it also achieved the highest color capacity in the development of Sony's display equipment. The display system processes signals at high speed and high precision at a high bit rate of 96 bits. This technical feature can not only effectively solve the problem of poor color expression of existing OLED panels under medium brightness, but also pass accurate gradient control to minimize color cast and brightness changes caused when viewing content obliquely on a large screen.
   In terms of color control, the color volume of OLED, LED and RGB-LED can be adjusted separately. By finely controlling the brightness of densely arranged RGB LEDs, bright areas in the picture can be vividly and realistically rendered, effectively avoiding the appearance of white color blocks, and at the same time ensuring that the light in dark areas is displayed just right and there will be no excessive darkness or insufficient light. situation. Compared with traditional local dimming processing methods, this display system is equipped with nearly twice the processing power and incorporates pixel correction technology to accurately reproduce subtle color differences, present accurate colors, and eliminate color cast problems.

为了让这款新型显示系统能够发挥出最佳性能，索尼积极携手多方行业伙伴共同推进研发工作。Among them, Sony teamed up with long-term strategic partner MediaTek to develop control processors. Mediatek has accumulated profound and mature technical experience in the field of TV SoC chips (Pentonic) and can provide strong technical support for this project. In addition, Sony has also cooperated with ROHM Semiconductor (ROHM) to focus on the research and development of LED driver integrated circuits; at the same time, it has collaborated with San 'an Optoelectronics to tackle key problems and fully promote innovation and breakthroughs in LED light source technology. By integrating the superior resources of all parties, Sony hopes to further improve the overall performance of the new display system, bring better and more cutting-edge display products to consumers, seize opportunities in the highly competitive display market, and lead new trends in industry development.
