People can’t live without the electronic screen, and constantly require higher resolution, higher contrast and more gorgeous screen images in order to approach the real visual experience. The screen technology is upgraded every 6-8 years. At present, it has reached the “ultra high definition” visual era.
Miniled is narrowly defined as a related screen product manufactured based on < 100um LED chips. It has advantages such as better color rendering effect, higher contrast, support for higher display pixels, and longer service life. It is an excellent technical path in the “ultra high definition” market. At present, the reserve of supporting technologies such as chips, packages and screens in the upstream and downstream of the industrial chain has been basically completed, and only mass production and application promotion are needed, and the ultra-high definition market will be developed.
According to estimates, in the next five years, it is estimated that the miniled direct display screen market is expected to reach a market scale of 35-42 billion yuan, and the miniled backlight display screen is expected to reach a market scale of 10-15 billion yuan. The total market demand of the two is expected to reach about 50 billion yuan, which will greatly boost the upstream demand for LED chips and led beads.
In addition, microled is the core solution of the next generation of display technology agreed by the industry chain. Its core definition is that the LED chip size is < 50um. The advantages of microled mainly include differentiation, high brightness, ultra-high resolution and color saturation, fast reaction speed, long service life, etc. compared with LCD and OLED, it is an upgraded version of miniled.
However, microled still has many technical problems to solve, including flip chip technology, massive transfer technology, thermal congestion and other problems, which lead to low yield and high cost. Although some manufacturers have launched microled display products, the actual chip specifications have not reached the micro level in the strict sense, and the cost is also high, which is still far from being widely accepted by the market.
According to the estimates of relevant research institutions, the market size of microled is expected to reach 100 million yuan in 2021, of which wearable devices such as smart watches are its main application direction. It is expected that the growth of microled is expected to maintain about 75% in 2021-2024, and the market size of microled will reach 5 billion yuan in 2024. According to the calculation of the mini / micro LED market demand, it is expected to drive the LED lamp bead Market by about 20-28.5 billion yuan and the LED chip market by about 12-17 billion yuan.
