Geng Jun from the North: The best technical route for future VR/MR - silicon-based OLED display technology close to 4K PPI

According to Jiwei.com, on October 26, 2023, the 6th China (International) Micro LED Display Technology and Industry Development Conference was held in Xinyu, Jiangxi. Geng Juncheng, the vice president of Chitron North, was invited to attend and deliver a keynote speech entitled "Mini LED driver development status and Micro LED technology roadmap". He started from the key link of driver IC technology and focused on the company's technology accumulation and industry contribution in the new display field

Micro LED, as the next generation display technology that the industry is paying attention to, has the characteristics of high resolution, low power consumption, high brightness, high contrast, high color saturation, fast response speed, thin thickness, and long life. However, at present, Micro LED displays still have technical difficulties such as mass transfer and subsequent detection and packaging. The high product cost means that the market potential of Micro LED still needs to be further stimulated.

Dr. Geng Juncheng mainly introduced the current status of the company's Mini LED driver development and core technologies as well as product breakthroughs in the direction of silicon-based OLED. As a technological extension of traditional LED displays, the gradual reduction of Mini LED display point spacing will exponentially increase the technical difficulty of chip design. Smaller LEDs have close to the limit of PCB process requirements, and issues such as power consumption, heat generation, and display effect consistency have become more prominent. Chipone North has concentrated on solving the above difficult problems through circuit optimization, architecture optimization, hardware-level correction, coupling crosstalk processing, PAM hybrid drive dimming and other methods to ensure better display effects.

With the introduction of the concept of the metaverse and the boom of the XR virtual display market, display technologies such as silicon-based OLED and Micro LED have ushered in a new revolution. Compared with other technologies, silicon-based OLED display technology can currently achieve a display effect close to 4K PPI, and has the potential to further improve, becoming the best technology choice for future VR/MR products

It is reported that Chitron North has been deeply involved in the field of silicon-based OLED driver chips for many years, and currently has corresponding high-standard products put into mass production. One of the 1.3-inch 4K micro-display silicon-based OLED integrated display driver chip ICNU1510 for VR/MR supports up to 4K*4K resolution, 90Hz refresh rate, 4032PPI pixel density and 5000nits brightness. It adopts international leading design, specifications and technology. The power consumption is lower and the overall performance is at the leading level in the industry. In order to further improve Micro OLED display performance, Chitron North has introduced its self-developed Foveated Rendering (foveated rendering technology in the gaze area) and DEMURA algorithm into the display driver chip ICNU1510, which effectively solves the problem of gaze area rendering and improves display uniformity. Greatly improves the VR/MR device experience.

Chitron North stated that it will continue to focus on the new display field in the future, continue to deepen its efforts in technological breakthroughs and performance improvements of driver ICs, and contribute China's "core" power to the collaborative innovation and development of the entire industry chain of the display industry.
