LEDinside Micro LEDforum 2018

"Micro LEDforum 2018:Micro LED key technical scheme and application market" is held on 12 day at the 201 room of the International Conference Center of Taida hospital, 12 days at the International Conference Center of Taida hospital. This seminar invites domestic and foreign leading manufacturers and experts from eLux, Uniqarta, QMAT, KIMM, Nitride Semiconductors, Topcon, Macroblock and other domestic and foreign leaders. The bottleneck of the Micro LED six major process is thoroughly parsed.

Micro LED & Mini LED business opportunity broke out, the output value of 2022 was nearly $1 billion 400 million

The symposium is stored in the super unveiled Prelude by the LEDinside research coordinator. In view of the development status and potential business opportunities of the outside world, the Micro LED has won the LCD and OLED in technical life, contrast, energy consumption, reaction time and visual angle, and the leading manufacturers such as Apple, Sony and Samsung have already been actively laid out. The sea smashed heavy gold to build the Micro LED whole industry chain, which would help promote the commercialization of Micro LED.

In addition, as Samsung, Sony, AUO and other big factories have shown the conceptual products of Micro LED in 2018, Samsung even has the desire to produce large size Micro LED television, driving more manufacturers to invest in development. According to the latest LEDinside report, it is estimated that the market value of Micro LED and Mini LED will reach $1 billion 380 million in 2022, of which $694 million will be contributed by Micro LED.

Micro LED technology is expected to import special display applications in the early days

However, at present, Micro LED still faces layers of technology bottlenecks, including six aspects of epitaxy and chip, transfer, full color, power driver, backboard and detection and repair technology. In the key transfer technology, with the advent of various transfer schemes, such as Pick & Place transfer, fluid assembly, laser transfer, and roller transfer, it is expected that more competitive technology will emerge in the future and will have the opportunity to speed up the development of Micro LED.

According to LEDinside, the initial Micro LED technology will have the opportunity to import special display applications, especially the specifications that LCD or OLED displays cannot reach, and will be complemented by Micro LED technology. Including the AR micro projection device with high luminance, HUD projection application for vehicle, and even the super large display billboard, Micro LED technology will be introduced in succession in the short term.

Micro LED six major technology bottlenecks and the latest breakthrough

As mentioned earlier, to develop Micro LED display still faces six major technical bottlenecks at present, in the full color and detection link, Nitride Semiconductors introduces the technical scheme to stimulate the full color pattern by the near ultraviolet LED chip in the meeting, and the V-Technology's RGB photoresist uses inorganic fluorescent material to prolong the service life; Topcon It brings the latest Micro LED luminance and chromaticity detection methods, and KLA-Tencor introduces the Micro LED surface defect detection scheme.

The next half of the agenda focused on the critical mass transfer. The United States new venture, eLux, has patented the assembly and positioning technology of the Hon Hai group, which can achieve maximum assembly speed. The eLux founder and the technology chief Paul Schuele also shared the actual application of fluid assembly transfer to make light-emitting displays. American new company SelfArray shows directional self - assembly technology to transfer a large number of Micro LED chips to PCB substrates through magnetic force. In the field of laser transfer, LEDinside invited the US new venture, Uniqarta, to introduce LEAP laser advanced placement technology; QMAT matched the detection scheme and used laser to do location transfer (Beam-Addressed Release). Finally, the South Korean Research Institute, KIMM, proposed a roller - roll technique. The technical feasibility of different solutions is given to the participants through the massive transfer scheme presented by the representatives.

In the driving part, accumulating technology introduces the latest Micro LED drive IC solutions, and the current progress of Micro LED in the development of display devices. The platform factory and lotus optoelectronics on the pressure axis analyzed the business opportunities of Micro LED technology in non display applications.

In summary, although Micro LED involves a wide range of industries, including precision machinery, semiconductor manufacturing process, testing and maintenance, huge transfer technology still remains to be broken and can not reach the level of mass production in the short term. However, from the current development trend, leading manufacturers are actively involved in the development of Micro LED, some of the technology has been progresses. It is estimated that the production of high - order products will be seen in the second half of 2018. Therefore, Micro LED still has great potential to become the next generation display technology, and the opportunity is available.
