On July 11, the 2023 Micro Display Industry Conference was held in Shenzhen, which invited more than 500 industry professionals from leading enterprises, experts and scholars in the global micro display industry and representatives of responsible persons of relevant institutions to share and discuss the latest achievements in advanced technologies, manufacturing processes and materials in the field of micro display, and their innovative applications in commercial large screens, mobile terminals, VR display devices, vehicle displays, meta-universe and other sub-fields.

Geng Juncheng, General Manager of Chipone LED Business Unit, was invited to attend the conference and delivered a speech.

The conference is sponsored by microdisplay industry alliance and Shengshi media "LED Screen Display World" magazine, and has been strongly supported by important associations and institutions in the industry such as LED Display Application Branch of China Optics and Optoelectronics Industry Association.

"High Grayscale Driver IC Technology Development Trend and MLED Product Application"

In the keynote speech session, Geng Juncheng, General Manager of Chipone LED Business Unit, shared the content of "Development Trend of High Grayscale Driver IC Technology and MLED Product Application" with online and offline guests.

Geng Juncheng introduced the different definitions of Mini LED backlight in upstream, middle and downstream enterprises, the technical difficulties and control problems of Mini LED backlight in small-size products, the technical route of Mini LED backlight and the parameters, characteristics and advantages of ICND8603B of Mini LED local dimming driver chip in North Mini LED.

About "How does the driver IC performance meet the requirements of the development trend of LED display?" This problem, Geng Juncheng focused on low power consumption, low gray high refresh, low gray correction, high integration, high frame rate, PWM+AM and other requirements, and further discussed the requirements of relevant driver IC products in line with the development trend of LED display.

He said that from the design point of view, to meet the low-power circuit design, the power consumption of the internal circuit of the IC must be optimized; On the load, the product should reach more than 48 channels of ultra-high integration, 128 scanning high scanning design; In terms of control, to achieve low power consumption of the control module, the power consumption needs to be reduced from 12.5 (W/㎡) to 2 (W/㎡); In terms of process, from 180nm to 110nm, 90nm, and even 55nm, it is constantly shrinking.

In addition, Geng Juncheng also conducted a detailed analysis from the needs of IC low-power consumption target, low-gray effect optimization, AM driver, PM+AM hybrid dimming, and accurate low-gray image quality performance. He said that he hopes that through the advancement of display technology, he will continue to meet the new application needs of the market and make technical reserves and innovations for the development of the micro-display market.

"Sofa Forum"  new trends in the development of the micro-display industry

Geng Juncheng participated in the "Sofa Forum" discussion session of the conference as a special guest, and under the presidence of Hong Zhen, Secretary-General of the LED Display Application Branch of the China Optics and Optoelectronics Industry Association, industry experts jointly conducted in-depth discussions on the current opportunities and challenges of microdisplay industrialization.

Is the COB era of micro-display coming? What is the signal of traditional home appliance display companies acquiring LED display upstream? In the post-epidemic era, the micro-display market has just recovered, why are many famous companies competing for layout? There are more monks and less porridge, where is the future of the micro-display industry? In the face of the above topics, the guests said that they will continue to increase the research and development and innovation of micro-display technology in the future to jointly promote the commercialization of the micro-display industry.
