On December 10, Shanxi GKGD Electronics Group Co., Ltd. announced that its patent for “a method of manufacturing Quantum Dot Micro MIP devices” has entered the examination and publication phase. The details of the patent are as follows:
This invention pertains to the field of semiconductor display technology and specifically discloses a method for manufacturing Quantum Dot Micro MIP devices, which includes the following steps:

Steps of the Quantum Dot Micro MIP Device Manufacturing Process:
- S1: Prepare raw materials
- S2: Sapphire coating
- S3: Large-scale transfer
- S4: Quantum dot groove
- S5: Quantum dot spraying
- S6: Quantum dot encapsulation
- S7: Laser debonding
- S8: RDL (Redistribution Layer) packaging
- S9: Device cutting
- S10: Device testing
The invention combines blue Micro COW (Chip-on-Wafer) technology with quantum dot materials to achieve color conversion, enabling the generation of red and green light. This significantly enhances the color saturation and detail of the display device, ultimately improving the overall display quality. The use of large-scale transfer technology and laser debonding ensures that the chip transfer and packaging processes are more efficient and precise, reducing loss during manufacturing and helping to control production costs. Additionally, the optimized cutting and packaging processes ensure the device’s performance and quality, while also increasing production efficiency.
