The
full name of LED is Light Emitting Diode, which is a semiconductor component
that can transform electric energy into Light energy. It is mainly composed of
five materials including bracket, silver glue, wafer, gold wire and epoxy
resin. It changed the luminous principle of incandescent tungsten light and
energy-saving light sanki toner, using the electroluminescence instead. Known
as the fourth generation of lighting source or green light source, LEDs have
the features of energy saving, environmental protection, long life, small
volume etc, and are widely used in all kinds of instructions, display,
adornment, back light, general lighting and urban night scene, etc.
According
to the different sizes, Mini LED is divided into two categories --50~100um and
100 ~200um, among which the most used is 100~200um size. In terms of different
application fields, Mini LED is mainly used in smartphones, automotive, TVs and
monitors. Among them, the application of Mini LED in the monitor industry
accounts for the largest market share, accounting for 68.38% of the market in
2020. LED for TV ranked second with 20.85% market share.
The
Asia-pacific region is the largest revenue market for the Mini LED industry in
the world. In 2020, the region accounted for 57.52% of the global market share
and the market revenue was $144.98 million. North America and Europe ranked
second and third with 19.82% and 18.44% market shares respectively. However,
based on data analysis and model derivation, we predict that the market share
of the Asia-Pacific region in the global Mini LED industry will continue to
decline during the forecast period, and will decrease to 53.51% by 2025. In
contrast, the market share of North America and Europe will increase to varying
degrees during the forecast period.
The
leading companies in the global Mini LED industry are all from the Asia-pacific
region. The top 3 companies are Epistar and San\'an Optoelectronics from China
and Nichia from Japan. In 2020, their market shares were 23.19%, 20.19% and
17.67%, respectively. The top 3 enterprises occupy more than 70% market share
of the industry, which shows that the industry has a high degree of market
concentration.
Epistar
manufactures and sells LED chips and epitaxial wafers, whose products are sold
in Taiwan and exported to various parts of the world. Today, Epistar has become a global major LED
supplier and works with some of the leading brands in the world to promote LED
applications on mobile screens, laptops, TVS and other devices.

According
to research data, the global market value of the Mini LED industry was $119.16
million in 2019 and grew to $252.06 million in 2020. Based on this data and combined with the
market environment and development rules, we conducted a series of function
calculations and deduced the data of the next five years with scientific model.
Finally, it can be predicted that by 2025, the total market value of the global
Mini LED industry will reach $2656.63 million, and the industry will develop
rapidly in 2021-2025.
Mini LEDs Have Significant Advantages and Are Expected to
be Upgraded Rapidly; Upstream Chip Manufacturing Will Benefit the Most
Mini
LED bears the characteristics of small-spacing LED with high efficiency, high
reliability, high brightness and fast response time, but the technical
difficulty is lower than Micro LED, LED is easier to realize mass production. Therefore, Mini LED is a transitional
solution between small pitch LED and Micro LED, and the product is expected to
be upgraded rapidly. In addition, compared with OLED, Mini LED has advantages
in yield, cost, energy saving and display performance. At present, the two key
packaging technologies of Mini LED, COB and IMD, have made breakthroughs, which
will strongly promote the rapid development of Mini LED in LCD backlight and
display field.
The
LED industry chain can be divided into three parts: chip manufacturing,
packaging and application. According to the benefit degree, the upstream chip
manufacturing will undoubtedly become the most beneficial link. In the
explosion growth of LED lighting industry, the upstream epitaxial and chip link
performance is the most elastic upward. Because the chip manufacturing in LED
industry chain technology content is high. Therefore, companies with R&D
technology, proprietary technology, and scale advantages will benefit the
most.
However, the extremely small size of the Mini LED presents challenges for electrode structure design, welding flatness and weldability, and packaging freedom. From the point of view of display, the size of Mini LED chip is very small. When transmitting red light chip in flip chip packaging process, the whole process is very complicated, and the chip transfer technology, yield and reliability of using process are technical difficulties. From a backlight perspective, end-products such as TVS and laptops require ultra-thin, Mini LEDs must maintain a small optical distance (OD), and have high requirements for light output control of the Mini LED chip and color consistency during use of the LCD panel. Thus, technical barrier has brought huge challenges to the development of the Mini LED industry.
