The new technology of Micro LED has attracted the attention of the market at this smart display exhibition. Hon Hai (2317) and Jingcheng Semiconductor, a subsidiary of Fucai (3714), announced at “Touch Taiwan 2023” that the two parties have jointly developed a new 0.12-inch micro-display with a pixel density of more than 6500PPI and a blue light brightness of 200,000 nits. Micro LED samples . Hon Hai said that this product can be widely used in smart glasses, AR/VR and other devices. The group will be committed to collaboration and technological innovation to expand business opportunities in metaverse applications such as virtual reality and augmented reality.
Considering the high-brightness requirements of AR applications, when the two parties cooperate to develop products, Jingcheng, which has rich experience in manufacturing III-V semiconductors and advanced process technology, optimizes the efficiency of Micro LED chips to ensure that the subsequent full-color conversion will not lose power in terms of brightness and chip performance. Balanced consumption; Hon Hai uses self-developed color conversion technology to further achieve 3600PPI full-color display effect.
Hon Hai pointed out that the main purpose of the cooperation between the two parties is to improve the efficiency of Micro LED. By optimizing the Micro LED chip structure and adopting new thin film protection technology, surface defects can be successfully reduced, external quantum efficiency can be improved, and product reliability can be improved.
Generally, high-PPI full-color samples cannot provide sufficient optical density of quantum dots due to the small pixel pitch, resulting in the leakage of unabsorbed blue light in high-brightness scenes, resulting in blue halos and color cross-colors between full-color pixels. Hon Hai Micro LED The manufacturing technology is built with semiconductor manufacturing process. Through high-efficiency quantum dot color conversion, combined with the group’s self-developed reflective inter-pixel light shield technology, it provides quantum dots with sufficient absorption optical density and prevents cross-color crossover between colors to produce high-purity Red light and green light achieve full-color display effect.
This time, Hon Hai has joined hands with Fucai to develop and manufacture blue-ray Micro LED processes, and to improve the 4um-pitch high-efficiency blue-ray pixel process development. The long-term goal is to invest resources in applications with growth potential to achieve differentiation and technological innovation.
