MINI/MICRO LED Display Technology Industry Has Entered A Golden Window Period

The rapid development of MINI /Micro LED is driven by market demand.

First, Zheng You炓 introduced the Micro-LED display technology and characteristics. Micro LED is a display technology of LED display miniaturized to micron level. It has two characteristics. One is the use of two-dimensional Micro LED array with high pixel density; The second is that each pixel can be addressable control and drive light independently. Micro LED display features low power consumption, high brightness, high resolution and color saturation, fast response, high contrast, wide viewing Angle, high energy efficiency, long service life and other performance characteristics. Therefore, Micro LED display technology has irreplaceable advantages and is called the next generation of display technology.

Zheng You炓 said that although Micro LED has many advantages, but the process technology is difficult, especially the massive transfer. An 8K Micro LED display, for example, requires more than 33 million LED cores to be transferred to the back panel. This process has high requirements for efficiency, accuracy and reliability.

Zheng You炓 pointed out that MINI LED, as a transitional technology for the development of Micro LED, is similar to the current small-spacing LED display technology in technology, but realizes the function expansion of small-spacing LED in display function. Compared with Micro LED, Mini LED has a very different manufacturing technology, but the display function is complementary. Therefore, MINI LED is not only a transitional technology for the development of Micro LED, but also fills the "technology gap" between the current small-spacing technology and Micro LED display technology, so there is a huge market space.

Zheng you 炓, MINI/MICRO LED direct display technology has two major characteristics: one is the MINI/MICRO LED module seamless splicing can be made into any size, any shape of the display, which is suitable for the development of large screen display. Second, MINI LED and Micro LED displays have ultra-high density pixel elements, which can enhance the HDR performance of LED display, have higher contrast, enhance visual experience, have clearer shadows, detail expression, and higher color depth.

Based on its characteristics, MINI /Micro LED technology has an extremely wide range of applications.

Large screen applications include TV, commercial screen, command and dispatch screen, security monitoring, smart city, etc. In the screen application including vehicle display, high order monitor, etc.;

Small screen applications include mobile phones, tablets, etc.

With the opening of 5G network and the development of new generation information technologies such as big data, cloud computing, Internet of Things and artificial intelligence, information display has become an indispensable part of 5G information technology ecology. The ubiquitous demand for display has become the fertile ground for the rapid development of MINI/MICRO LED display industry.

Large-size direct display and MINI LED backlight are the development direction of MINI/MICRO LED display industry.

Zheng You炓 put forward two industrialization directions of MINI/MICRO LED display. One is a large ultra-high definition display. Based on its own advantages, Micro LED is suitable for developing large scale ultra-high resolution displays. By enlarging the size of the screen and extending the viewing distance, it is easy to achieve high resolution. As a transition technology from small spacing to Micro LED, MINI LED has low technical difficulty, and its performance exceeds that of small spacing. It can also achieve super-large high-resolution display screen through seamless module splicing. In order to meet the different requirements of resolution in different application scenarios, we can cooperate with Micro LED and MINI LED to develop super-large screen series display products based on their respective advantages.

The second is MINI LED backlight technology, namely MINI LED backlight LCD display, it uses MINI LED as a straight down backlight of LCD panel. The chip arrangement with dense light source on the straight down backboard can realize zoned light control, so that the bright area is brighter and the dark area is darker, thus greatly improving the contrast of LCD, achieving ultra-high contrast and black field display, high color gamute, high dynamic range, and improving the display quality. In addition, the MINI LED, as a backlight, also allows the LCD to achieve better brightness uniformity over smaller light mixing distances, making the display thinner and even comparable to OLED. In addition, compared with OLED, Mini-LED backlight LCD also has the advantages of no stroboscope, no burning screen, long working life and low production cost. As a result, MINI LED backlight technology helps LCD performance improve and enhance its competitiveness with OLED.

Finally, Zheng You炓 Academician on the development of MINI /Micro LED industry put forward several views. First, to meet the urgent needs of the market, the development of MINI /Micro LED display technology industry is the right time. Second, MINI /Micro LED display technology will lead to revolutionary changes in the display field and is expected to reshape the new pattern of the display industry. Different display technologies will give full play to their respective advantages and open up their own development fields and application scenarios. Third, MINI /Micro LED large-size high-resolution direct display and downside-type partition backlight technology is widely used, especially when super-large size and ultra-high-definition high-end engineering display enter the consumer display, the market space will be very huge. Fourth, MINI/MICRO LED display opened a new stage in the development of LED display technology.

Academician Zheng believes that MINI /Micro LED display is still a new technology in development and has ushered in a new golden window period. MINI/MICRO LED industry has entered a new stage of development. According to the rule of display technology development and upgrading, there will be a golden growth period of seven to eight years in general.
