The entire history of display screens has grown through continuous technological breakthroughs. The rise of CRT displays in the mid-20th century promoted the establishment of television broadcasting systems; then plasma TVs brought about a high-definition revolution; in the 21st century, display devices developed toward thinner and lighter weights, and liquid crystal displays gradually became the mainstream display medium.
However, due to the inherent shortcomings of LCD technology in terms of splicing seams and high-brightness and high-contrast presentation, LED has become the first choice for larger-size displays, such as large indoor and outdoor commercial advertising screens, security monitoring command centers, stage displays, etc.
Mini LED and Micro LED are upgraded versions of LED in the direction of ultra-high definition display and product miniaturization.
Compared with traditional LED displays, MLED displays have the characteristics of high brightness, high resolution, low power consumption, high integration, high stability, color fidelity, long life, and good stability. It is regarded as the next generation display solution and can be widely used in any display situation from the smallest to the largest size.
From indoor and outdoor professional large screens, to cinema screens, virtual shooting, smart car displays, to consumer-grade flat-panel displays, as well as AR/VR/MR, spatial display, soft Sexual display, transparent display, wearable display, optical communication, optical interconnection, medical detection and other fields.
//Policy support In the past three years, central and local government policy documents have been issued frequently, clearly proposing to support the development of new MLED display technology. Five departments including the Ministry of Industry and Information Technology pointed out in the "Virtual Reality and Industry Application Integration Development Plan (2022-2026)" that they will focus on promoting the upgrading of micro-display technologies such as MLED, and require the key layout of forward-looking industries such as MLED display. The Ministry of Science and Technology emphasized in the national key R&D plan that it will carry out key special projects in "new displays and strategic electronic materials"; in the "14th Five-Year Plan" issued by many provincial and municipal governments, they specifically proposed to support the development of MLED new display technology. So far, at least 17 provinces and cities have formulated MLED-related policy plans.
