What Does MicroLED Rely On To Become The Future Of The Display Screens

Author : China display screen supplier

Update time : 2020-10-12 15:29:50

At the beginning of its appearance, MicroLED is considered to be the first display technology without size restriction in history, and has become a recognized future development direction of the display screen, so it is strongly sought after by the manufacturers of the whole display screen industry chain.

What Does MicroLED Rely On To Become The Future Of The Display Screens

The basic features of MicroLED technology are excellent: this realistic technology has the characteristics of wide color gamut, high brightness, low power consumption, high stability, long life, wide viewing angle, high dynamic range, high contrast, high refresh rate, transparency, support for seamless connection and integration of internal sensors.

Although these special performances can be realized on LCD, OLED and QD panels respectively, MicroLED technology can realize these technical features at one time, and there is almost no obvious deficiency, and it is also the most comprehensive display panel technology under technical conditions.

In addition to the promotion of traditional display panel manufacturers, downstream manufacturers such as Apple are also involved in the research and manufacture of this technology, and the number and field of participants who follow MicroLED technology is increasing. Although MicroLED is not yet their main focus, they will invest more in this area to ensure that they can catch up when the MicroLED takes off without getting stuck by upstream manufacturers.

Under the premise that the LCD and OLED markets have been carved up, participating in the development of the next generation display technology can not only bring new competitive opportunities for all parties, but also break the current regional clusters and advantages, and form a new industrial structure. Therefore, having the opportunity to break the situation is the primary reason why MicroLED technology has been vigorously promoted by all parties since its birth.

Because the MicroLED unit is too small, it directly leads to a substantial increase in the surface area of each unit on the final cost panel, which also greatly increases the complexity of manufacturing and brings more potential problems. While maintaining high efficiency in mass production, it is necessary to reduce the chip size and improve the chip design and manufacturing process.

The production of the final MicroLED display products (mobile phone screen, TV, display, etc.) also involves more technologies and processes, including epitaxy, lithography, chip manufacturing, substrate removal, inspection, mass transfer, bonding and interconnection, testing, maintenance, backplane and driving IC, etc. After years of development, although many technical problems have been solved and the technology has become more mature, more technological challenges have been found in the manufacturing stage.

A few years ago, the main development goal of the chip industry was to improve the manufacturing process, reduce the chip area, increase the energy consumption ratio and so on. In recent years, more and more emphasis has been placed on AI, auxiliary chips, special chips and other more comprehensive directions, advocating to improve the processing capacity of chips from a specific and global point of view, rather than blindly improving computing performance.

Therefore, enterprises in the MicroLED industry pay more and more attention to technologies such as overall optimization, image improvement, application scene matching and mass production equipment, rather than blindly pursuing the performance limits that this technology can bring. These practical trends also effectively enhance the practical value of this technology, and further promote its commercial process.

The demand for MicroLED display can be analyzed from two aspects: the first is to replace the current products in the market as a realistic technology with better performance, and the other is to open up some new display application scenarios by virtue of this new technology. For the first scenario, MicroLED has a very broad application prospect in augmented reality / mixed reality (AR / MR), virtual reality (VR), very large video displays (over 100in), televisions and monitors, car displays, mobile phones, smartwatches and wearable devices, tablets and laptops.

In order to compete with "traditional" technologies, MicroLED should determine its unique market value to highlight its advantages and give better play to the characteristics of these technologies. To create a new display market, MicroLED needs to provide features that cannot be enabled by other alternatives, including displays with custom shapes and displays that need to integrate various sensors.

As a new display technology, MicroLED has received wide attention because of its all-round display performance and the advantages of highly integrated mainstream displays. However, MicroLED is still limited by many bottleneck technologies, especially in the production process, even if the industry can make a breakthrough, it will take a lot of time to achieve real mass production and commercial use.
