Ultrafast Laser Processing: New Advances For Display Manufacturing

Ultrafast laser processing offers cutting-edge solutions for modern display manufacturing, addressing the demands of precision, efficiency, and compatibility with evolving technologies like flexible OLEDs. Utilizing femtosecond and picosecond laser pulses, this technique enables controlled energy deposition for applications such as repair, selective ablation, and high-quality cutting.

Key advancements include repair processes for defect correction, Hole in Active Area (HIAA) techniques for flexible and rigid OLEDs, and cutting processes designed specifically for foldable displays. These processes minimize damage, including burrs, delamination, and microcracking, while maintaining small Heat Affected Zones (HAZ) of less than 30 µm. Cutting speeds range from 50 to 500 mm/s, ensuring fast and efficient production cycles.

Beam shaping technologies further enhance performance by enabling precise focus control and minimizing roughness or chipping. This is particularly beneficial for applications like thin glass cutting, where laser ablation or volume modification methods create smooth, strong edges with minimal post-processing.

These innovations improve manufacturing yields and are adaptable for both large-scale production and specialized applications. With ultrafast laser processing, manufacturers can achieve high-quality display components that meet the rigorous demands of digital, immersive, and interactive displays. This technology underscores the versatility of lasers as essential tools in modern industrial processes.
