In recent years, with the continuous development of science and technology and the needs of consumers to upgrade the visual experience, LED display technology has continued to develop towards the fine pitch and high density. From fine-pitch LEDs to mini-LEDs, micro-LEDs continue to expand. Compared with other technologies, Mini-LED has obvious advantages in contrast, brightness, resolution, color gamut, etc. It is expected to replace OLED as a new generation of mainstream display technology.

With the continuous technology development and the gradual production increase, the cost of mini-LED backlighting drops by 15-20% every year. In this context, many manufacturers such as Huawei, Samsung, and Skyworth have entered the market and launched mini-LED TV products. In the field of mini-LED, TCL, as the first layout and batch manufacturer, stood out among many manufacturers and became the leader of the mini-LED industry.

The Mini-LED Track is Full of Imagination

According to the investment data of CITIC Construction, the development of mini-LEDs will usher in a golden period of development in the next five years from the perspective of market trends. Mini-LEDs show that the number of terminals will increase from one million to more than 40 million. the five-year compound growth rate of the market size will reach 140%, and the growth rate will be close to 10 times.

In the field of mini-LED TVs, Omdia announces that shipments of mini-LED backlit TVs are expected to reach 25 million units by 2025, accounting for 10% of the entire TV market, far exceeding OLEDs.

The Industry Chain Still has a Potential for Growth

From chip manufacturing and mini-LED chip packaging to equipment links and product terminals, the entire industry chain is increasing investment in mini LEDs.

Judging from the layout of upstream LED chip manufacturers, San’an Optoelectronics, HC Semitek, Epistar, etc., have increased their investment in mini-LEDs. San’an Optoelectronics spent 12 billion yuan for mini/micro-LED extension, chip products, and related applications.

At present, the size of mini-LED chips is shrinking, and the technology path is basically mature. Domestic manufacturers have the capacity for mass production.

Data predicted that people would consume 1.347 million 4-inch LEDs in 2021, accounting for 5.6% of the current total chip production capacity and becoming a new round of LED chip growth momentum.

Midstream chip packaging manufacturers such as Nationstar, Hongli Zhihui, AMTC, and Refond, are optimistic about the mini-LEDs and have joined the research and development and production of mini-LEDs.

Mini-LED display packaging mainly adopts flip-chip packaging. Currently, midstream LED packaging factories have produced mini-LED products, and are actively cooperating with downstream display factories and terminal manufacturers. For example, Nationstar has invested 1 billion yuan in mini-LED packaging, and Refond has built China's first mini-LED automated production line.

For downstream of the industry chain, many panel manufacturers such as CSOT, BOE, and Leyard vigorously expand the mini-LED market. As a subsidiary of TCL, CSOT started the research and development of mini-LED technology as early as 2016. Because of the long-term in-depth cultivation and accumulation of mini-LED, TCL achieved mass production of mini-LED TVs in 2019.

Although upstream, midstream, and downstream manufacturers are increasing the layout of mini-LEDs, there are still a lot of opportunities for optimization and improvement in the mini LED industry chain.

On the one hand, mini-LED is only in the landing stage of industrialization in terms of technological optimization. Although many TV manufacturers have launched mini-LED TVs, it is still challenging to introduce basic parameters such as the number of partitions. At the same time, the majority of mini-LED TV products are positioned as high-end products. It is worth looking forward to exploring mid-end and low-end products in the future

On the other hand, the mini-LED backlight can reduce cost. According to Trendforce data, the cost of the backlight module for mini-LED products accounts for 66% of the total cost of the display. Reducing the cost of backlight modules and releasing industry potential is also the key to mini-LED market expansion.

The era of the big screen has arrived. As a new generation of display technology, mini-LEDs are entering a golden age of rapid development with unparalleled advantages over LCD and OLED. With the joint promotion of the industry chain, the development of mini-LED has a bright future.
