69‐1: Ultrafast UV Laser Trimming Process Characteristics Analysis for Flexible Display Panels

This study investigates the laser trimming characteristics of ultraviolet (UV) and deep UV pulse lasers for processing multilayer display panels. The influence of pulse laser parameters, including pulse duration and wavelength, on trimming quality and thermal effects was analyzed by measuring cutting profiles and ablation efficiency. Experimental results reveal that trimming quality and efficiency in multilayer display panels are significantly affected by laser parameters. In particular, the interfaces between layers are highly influenced by differences in optical properties, optical field distribution and thermal characteristics, with layer‐specific optical absorbance playing a critical role in adhesion quality. These findings highlight the importance of optimizing laser parameters to enhance ablation quality in multilayer structures. This study provides insights into the mechanisms of multilayer laser trimming, offering guidance for determining optimal conditions for advanced display panel micromachining and improving the quality of laser trimming for cutting‐edge technologies.
