Micro LED display and Mini LED backlight technology are undoubtedly the focus of the 2018 consumer electronics or display technology exhibition.Major manufacturers including samsung, SONY and au are all showcasing relevant conceptual products. Samsung even reported that it hopes to mass produce super-sized Micro LED TVS, which will bring more manufacturers into development.According to the latest report of LED research center of jipang consulting (LEDinside), it is estimated that the market value of Micro LED and Mini LED will reach $1.38 billion by 2022.

The new technology will accelerate the development of Micro LED

According to chu yuchao, research associate of LEDinside, Micro LED is still facing many technical bottlenecks, including epitaxy and chip, transfer, full color, power drive, back plate and detection and repair technology.In the past, it was generally believed that the biggest bottleneck was transfer technology. However, with the emergence of various transfer solutions, such as Pick & Place transfer, fluid assembly, laser transfer printing, and roller transfer printing, it is expected that there will be more cost competitive technical solutions in the future, which will have opportunities to accelerate the development process of Micro LED.

It is observed that Micro LED technology will have the opportunity to be introduced into special display application products at the initial stage, especially the specifications that LCD or OLED display cannot reach, which will be supplemented by Micro LED technology.Micro LED technology will be gradually introduced in the short term, including AR miniature projection device with high brightness requirements, HUD projection application for vehicles, and even super-large display billboards. LEDinside estimates that Micro LED will be worth $694 million by 2022.

Mini LED high-end backlight market demand looks prosperous

Considering that there are still many technical barriers to overcome in Micro LED technology at the present stage, many manufacturers will launch Mini LED backlighting scheme in 2018, hoping to attract the market to buy.LEDinside estimates that displays using Mini LED backlighting technology will be available in the second half of 2018, and the value of Mini leds will reach $689 million in 2022.

Different from the traditional LED backlight, Mini LED chip size is smaller, and with vertical backlight and area lighting technology, so the consumption of LED chip will show a multiple growth, become an important application to support the demand.

However, the cost structure of Mini LED backlighting is still too high for mainstream display products in the short term,In addition, there are still problems of heat dissipation and power consumption to be solved, so the market that can be entered in the future is still dominated by high-end consumer products, such as game notebooks, game monitors or screens for special applications, as well as niche products such as high-end TVS with high resolution, high contrast and high color saturation.This type of products attach importance to specifications and have low price sensitivity, which will become the main battlefield for various manufacturers to realize technology differentiation by using Mini LED backlight.
