Micro LED Patent Overview
On October 22, 2024, the National Intellectual Property Administration of China revealed that HYMSON Laser Technology Group Co., Ltd. has applied for a patent titled “Micro LED Repair Device and Method,” with publication number CN118789115A and an application date of July 2024.

Innovation in Micro LED Repair
The patent summary indicates that this invention discloses a Micro LED repair device and method. The Micro LED repair system consists of an ultraviolet (UV) nanosecond subsystem, a UV femtosecond subsystem, a laser propagation path subsystem, and a laser output subsystem. The nanosecond laser output from the UV nanosecond subsystem and the femtosecond laser output from the UV femtosecond subsystem are transmitted through the laser propagation path subsystem to the laser output subsystem, which is responsible for laser processing.
Efficient Repair Processes
The Micro LED repair method utilizes the Micro LED repair system to execute the chip removal and pad re-soldering processes. This invention integrates UV nanosecond and UV femtosecond lasers within a single device, allowing for timely selection and enhanced processing efficiency. Additionally, both UV nanosecond and UV femtosecond subsystems share the laser propagation path and laser output subsystems, thereby reducing overall costs.
