The hottest technology bottleneck has been gradual

  • Detail

The technical bottleneck has been gradually overcome, and micro led mass production is just around the corner.

since micro LED technology came into people's vision, it has attracted the attention of the LED display industry, and is even considered to be the tuyere of the next display technology. However, since some key technologies of micro led have not been broken, the question of whether micro LED can achieve mass production has not been answered. Recently, however, apple, the leading enterprise in the electronics industry, reported that it is expected to mass produce micro LED screens equipped with off-screen cameras in 2021

microled has outstanding advantages, attracting attention and transferring a large amount of attention to become the biggest problem.

when it comes to micro led, you can't help comparing it with OLED and LCD, which are widely used in mobile devices at present. As a composite integration technology combining display technology and LED light-emitting technology, micro LED can independently control the pixel, emit light alone, and has the characteristics of high brightness, low power consumption, ultra-high resolution and high color. If combined with nano wiring, micro LED can even make subminiature led achieve the effect of flexible screen, which has broad market prospects and is regarded as a new generation of display technology that may subvert the industry

micro LED technology is excellent, but at present, there is still no solution to the problem of how to transfer a large number of micron sizes to the circuit substrate, making it far away for many enterprises to realize the mass production of micro led

at present, due to the small size of watches, etc., it is not difficult to meet the LED size technology of small screen display equipment at the LED chip end. Theoretically, small batch production can be achieved. However, in the actual production of small screens, the problems of product testing, repair, consistency and so on are also difficult. Since micro LED can no longer be divided into bin, everyone temporarily adopts quantum dot scheme to solve the consistency problem. From the perspective of product structure, this scheme is certainly not the ultimate important. It is the beam moving pole solution for the experimental machine. It can only be said that it is a relatively feasible commercialization scheme at present. At present, the solutions to repair problems are mostly for large screens, and whether it is suitable for small screens remains to be discussed

the technical bottleneck is gradually overcome, and micro led mass production is just around the corner.

although the technical problem of micro led mass production is difficult to overcome, the huge advantages revealed by micro led have attracted the attention of major display manufacturers, semiconductor manufacturers and LED manufacturers around the world. All manufacturers are stepping up the development of breakthrough technologies, hoping to win the market

as the first enterprise to introduce micro led into the public eye, Apple was placed high hopes at the beginning, and was considered to be the manufacturer with the most ability to bring large quantities of consumer grade micro led to the market. After unremitting efforts in recent years, Apple had already announced that it would introduce micro LED technology into wearable devices such as apple watch, which could well solve the current pain points of watch itself, such as frequent charging and outdoor visibility

in addition, Samsung followed suit, investing a lot of money in R & D and production. For example, the grain size of Samsung's new generation micro LED TV is only 30um x 50um. At present, the specification of measurable products has reached 15um x 30um, and samples have been sent to different customers. In the future, the next generation of grain specification is expected to be 2.5um x 2.5um, which can be applied to Small-size wearable devices. It is expected that mass production will be expected as soon as the second half of 2019. At CES 2019, we will see new micro LED products of different sizes and brands from Samsung, covering various applications of small and large sizes

at present, in Taiwan, China, many display manufacturers will not miss micro led, a screen technology that can compete with OLED in the future. 2) quality technology, including crystal optoelectronics, Youda optoelectronics and qunchuang optoelectronics, have actively invested in the research and development of micro LED display related technologies. Of course, manufacturers in Chinese Mainland are not willing to lag behind. In terms of led enterprises, whether upstream, midstream or downstream, enterprises are actively deploying micro LEDs. It is worth mentioning that in the semi annual report of 2018, all led listed companies also reported on the progress made by the hydraulic universal testing machine cro led manually controlled by MI in the first half of this year

just as the technical bottleneck of antirust agents applied on the processing surfaces of major wiping machines is gradually overcome, micro LEDs will embark on the road of mass production in 2019, starting from small and medium-sized displays. Smart watches, augmented reality (AR) and hybrid reality (MR) devices are the earliest applications, followed by tablet computers and high-end TVs. It is expected that small shipments will be carried on 6.1 million devices. After 2021, the growth gradually accelerated, and the intelligence highly concerned by the industry began to introduce micro led, and accelerated in 2022 and 2023. The total equipment carrying capacity will exceed 50million, officially exceed 100 million in 2022, and challenge 250 million equipment carrying capacity in 2023, leading to the explosion of the industry

the development of an industry is bound to be inseparable from the emergence and application of new technologies. The success of a new technology ultimately depends on the joint efforts of all manufacturers. Micro LED technology is becoming more and more mature and widely used, which will create immeasurable value for the development of the entire LED display industry
