The manufacturing of display device with new principle, such as the Mini LED device, is one of the most competing focuses in academic frontier and it is obviously significant for the national economic and security strategy. Particularly, the low-defect and controllable manufacturing of quasi-freeform quantum dot (QD) lens with sub-millimeter scale determines the display quality of Mini LED devices, which is the key for Mini LED devices applying to high-quality and high-resolution display. This project aims to establishing the theory of semi-constrained differential pressure driven manufacturing for quasi-freeform QD lens of Mini LED devices, and focuses on the basic researches on key issues including the spectral regulation mechanism, the deformation control mechanism, and the forming defect inhibition mechanism, breaking the limitation in manufacturing size of sub-millimeter quasi-freeform structures in LED devices, as well as realizing the low-defect and controllable manufacturing of quasi-freeform QD lens on Mini LED chips. This project can achieve the breakthrough of the manufacturing theories and methods for QD-Mini LEDs, greatly contributing to the theory and technology developments of miniature LED display device manufacturing.
