Despite these obstacles, the LED market is projected to experience significant growth, driven by the adoption of Micro LED and Mini LED displays, increased penetration in automotive applications, the demand for energy-efficient agricultural lighting, and the expansion of LED display applications.

Micro LED Technology Challenges:
Micro LED technology faces several technical hurdles that need to be overcome for its successful implementation. One of the primary challenges lies in the microfabrication process, which requires precise control and manipulation of tiny LED components. Additionally, the mass transfer technique, which involves transferring thousands or even millions of micro LEDs onto a substrate, poses a significant challenge in terms of accuracy and efficiency. Another critical aspect is the bonding technology, which ensures the connection between the micro LEDs and the substrate, enabling proper electrical and optical performance. Lastly, achieving accurate and vibrant color reproduction in Micro LED displays remains a challenge that researchers and manufacturers are actively working on.

Projected Growth of LED Market:
Despite the obstacles faced by Micro LED technology, the LED market is expected to witness substantial growth in the coming years. As Micro LED finds its way into wearable devices, automotive displays, and large-format applications, the market value of LED is estimated to reach 21.013 billion USD by 2027. The increasing adoption of Mini LED displays, the rising penetration of LED in automotive applications, stable growth in HDR/Mini LED automotive displays, the demand for energy-efficient agricultural lighting, and the expanding scope of LED display applications are the key drivers for this growth. The compound annual growth rate (CAGR) between 2022 and 2027 is projected to be around 8%.

Shift towards Six/Eight-Inch Wafer Production:
In response to the evolving demands and requirements of Micro/Mini LED technology, LED manufacturers are gradually shifting towards the production of six/eight-inch wafer substrates. Major players in the industry, such as Nichia, ams OSRAM, Epistar, Lextar, Samsung LED, Sanan, and HC SemiTek, are investing in the development and production of larger wafer sizes. According to TrendForce analysis, the production share of six-inch and above GaN LED wafers is expected to increase from 5% in 2022 to 15% by 2027. This shift towards larger wafer sizes is expected to enhance production efficiency and drive down costs, ultimately benefiting the LED market as a whole.
