the technological innovations have attracted a lot of attention in the industry,

especially in recent years,major companies have combined MINI LED technology with small spacing, and launched MINI LED small spacing products,which have been heated up by industry insiders,and MINI small spacing products have instantly become a well-deserved "big star" in the LED display industry.
Small pitch meets bottleneck and MINI LED "icing on the cake" 

In 2018, after several years of rapid growth, the small pitch still became the most popular product segment in the LED display industry. In order to expand the market share, the major LED display companies have increased their strategic layout in the small pitch market. . At this stage, with the continuous optimization of product raw materials and the continuous upgrading of research and development technology, the spacing of LED display beads can be achieved with small spacing products below 1mm, which is sufficient to meet the market's requirements for product spacing. However, as the small-pitch market continues to mature, major screen companies have encountered technological innovation bottlenecks in the research and development of small-pitch products. In addition to continuously getting smaller and smaller pitches, they have no way to start at other technical levels. At this time, the emergence of MINI LED, for the small-pitch market, is undoubtedly sending charcoal in the snow, bringing new vitality.

Many people are confused, what is the MINI LED? Actually, MINI LED is not a form of MINI, because the chip size used is about 80-150 microns, which is much smaller than the small pitch of about 100-300 microns,that's why it is called MINI LED. At present, the MINI LED widely used in the market has a size of about 100 microns. It can not only be manufactured and tested using traditional processes and testing methods, but also can meet the requirements for high-definition display on mobile phones, TVs and other products,so it receives a lot of attention.

For the whole LED display industry, the small-pitch LED market has become "the most important capacity consumption point." However, this trend will change after the advent of MINI LED technology. In terms of substrate consumption, MINI LED uses 100-micron-sized LED crystals. Compared with the traditional small pitch, the substrate consumption is only 4% of the latter. This not only saves the cost of substrate materials, but also facilitates the manufacture of more terminal LED display products under limited LED upstream production capacity, reduces the proportion of upstream material costs in LED displays, and solves the "big picture" of traditional small-pitch LED screen products. "Waste", it solves many fatal pain points such as poor consistency and granular display of picture pixels caused by traditional small-pitch displays, and greatly improves the effect of low-brightness grayscale display.

Due to the product advantages brought by MINI LED, manufacturers in the industry refer to small-pitch LED products using MINI LED technology as "third-generation small-pitch LED" products. Leyard, which has the largest market share in the small-pitch LED market, said that it will be willing to launch products with MINI LED technology; in addition, at this year’s LED Guangzhou exhibition, China Guangcai has already launched the MINI COB small-pitch screen. , Was asked by a large number of viewers. The leading small-pitch companies in the industry have taken actions one after another, which means that the widespread use of MINI LEDs in the small-pitch market is just around the corner.

There are many difficulties in production. LED screen companies still need to work hard!

From the above advantages that MINI LED brings to the small pitch, MINI LED and small pitch are almost a "match made in heaven". However, if MINI LED is to truly land, many difficulties need to be overcome.

First of all,from the perspective of packaging technology,smaller crystal particles must be combined with chip-level COB packaging technology to give full play to its performance advantages,however, the small pitch of COB technology has not achieved large-scale popularization,which is MINI LED The packaging brings huge problems; secondly,compared with the traditional small-pitch display,MINI LED faces the problem of "super energy transfer",that is, a 6-inch substrate can produce 100-micron LED crystals up to 165 Ten thousand,how to transfer so many crystals to the drive circuit board in accordance with the display requirements is a difficult task for the current technology.

In addition, compared with traditional small-pitch products using SMD packaging, the integration of MINI LED technology and COB packaging as a new technology will surely increase R&D costs. Therefore, due to cost advantages, SMD-packaged LED products It is still the focus of all packaging manufacturers to expand production. If MINI LED cannot control a reasonable price, it will be difficult for its market to perform on a scale. Therefore, how to control costs will become the next direction for LED screen companies to work hard.

Although MINI LED still encounters many difficulties in the development of the small-pitch field, it can be known from the news released by major companies that many A-share companies in the market have begun to deploy in the MINI LED field, and many of them said Mass production has been achieved. This is undoubtedly a good omen for MINI LED. Only by getting the attention of major companies can breakthroughs in technology be achieved faster. By then, I believe that the small pitch will also catch the wind of MINI LED and complete a new transformation.
