The information display device is not only capable to deliver the content on the plane of the display screen， but more importantly， to display the content in a real three-dimensional space， making the natural interaction between individuals and information possible. Micro-LED displays have received much attention because they have the potential to bring us into a new era of truly immersive and interactive experience. Fast response time， micro size， wide environment temperature， and long operating lifetime， enable Micro-LED display for almost all display application， even flexible and transparent display. By reducing the diameter of LEDs， they show great promise in very high pixel density display. It is believed that Micro-LEDs could pave the way for realizing highly integrated semiconductor information display （HISID）， embracing the next generation information display technology.

The development history of display technology was briefly reviewed， and the development trend of display technology was discussed under the guidance of visual perception requirements and carbon peaking and carbon neutrality goals.Both the improvement and optimization of existing display technology， and the innovation and development direction of new display technology in the future were referred to.

With reference to the major technological trends of high luminance， wide colour gamut， high contrast and high immersion in new display technologies， the progress of research on visual perception and health were introduced and analyzed in the areas of luminance perception and adjustment， colour performance， high dynamic range optimization and near-eye display， in order to provide a reference for the development of new display technologies.

OLED technology has developed rapidly and has been widely used in small and medium size displays. At the same time， industry is waiting for large-size OLED display for high-end TV. Printed OLED has obvious advantages in the field of flexibility and high PPI， and printed QLED could further strengthen the advantages of printed display technology in color gamut， life time and cost. At present， the key elements such as technology， materials and equipment have gradually matured， and the prelude to the industrialization of printed display in China has opened up. In response to this trend， building China's printed display industry chain， especially the localization of OLED/QLED materials， inks and related equipments， is an important guarantee for the success of China's printed display industry， which requires extensive cooperation among academia， industry and the industry chain.
