For a long time, LEDs have played an important role in the display industry. The application scenarios of traditional LED displays are mainly traffic lights, large screens in command centers, etc. However, in recent years, traditional LEDs are gradually entering a mature period or even a decline period. In the current situation of overcapacity and increasing inventory pressure in the industry, where is the future of the industry?
What is Mini LED?
In order to counter the dominance of Korean OLEDs and also to find new growth points for LEDs, China's LED chip and packaging companies have begun to actively develop the new generation of display technology Micro LED, but Micro LED still has many problems to be overcome in terms of technology and cost. Therefore, Mini LED is proposed as a transition technology.
The key to current LED display micro-pitch is the miniaturization of the chip. The concept of Mini LED originated in Taiwan, which means that LED chips with a grain size of about 100 microns can be used as the backlight of the display after arraying the LED chips. Mini LED technology can reach millions of contrast ratios, and the visual experience is clearer and more comfortable. It is comparable to OLED in some performance, and has broad application prospects in the display field.
Manufacturers promote the maturity of Mini LED products
As a new display technology, Mini-LED has received widespread attention in the industry in the past two years. Driven by many manufacturers, the current Mini LED display technology and products are becoming more mature, and the market applications are gradually increasing.
As early as June 2018, Lianjian Optoelectronics released Mini LED products, which effectively solved the pain points of the LED display such as ink color consistency, splicing, light leakage, protection, and maintenance;
Huaxing Optoelectronics started to research and develop the Mini-LED technology route in 2018. In March 2019, it produced an active matrix-driven 65-inch Mini LED backlight TV; Guoxing Optoelectronics ’new Mini LED display product IMD-M07 has a 0.7mm dot. Pitch, mainly for 4K and 8K displays; BOE is working on Mini LED display technology and Micro LED display technology, BOE Chairman Chen Yanshun said that glass-based Mini LED backlight products will be officially launched in 2020; Jingtai shares, Zhaochi Stocks, Dongshan Precision, etc. all have Mini LED backlight products shipped in batches ...
In the exploration stage, the micro display industry has not yet formed a unified technical standard. Different types of products and technologies help promote industrial standardization and continue to mature. Therefore, various types of technology products launched by various enterprises are worthy of recognition.
Poor technology development
The development of Mini LED is not a smooth road either. Although from the perspective of technological research and development, Mini LED does not require too many breakthroughs in technological innovation, and its manufacturing is relatively difficult, but when a product is equipped with thousands or tens of thousands of LED particles, the yield to the enterprise There is a high demand for improving and reducing the cost of operating capabilities. In addition, related supply chains including parts making, testing, and sorting need to be in place. Therefore, although the LED industry's upstream and downstream supply chains intend to promote Mini LED mass production, the overall application take-off is still slower than expected.
However, in 2020, Mini LED is finally expected to enter the growth stage of real-quality production and shipment. Research institution TrendForce pointed out that Mini LED will usher in a period of rapid development from 2019 to 2020, and its output value will reach nearly $ 1.7 billion in 2022.
Conclusion: In 2020, Mini LED is expected to gradually enter the boom cycle. The maturity of the industrial chain will accelerate the increase of Mini LED penetration rate and is expected to become the next growth point of the LED industry. LED manufacturers should actively strive to keep pace with the times, based on their own market positioning and goals, with appropriate strategies to meet the changes and challenges brought by new technologies, and seek greater development space. As Micro LED technology matures gradually, Micro LED's advantages in energy consumption will gradually become apparent.
