To address the issues of debris, noise, and tool loss in traditional mechanical breakage, ultrashort-pulsed laser interior marking technology is employed in this study to achieve green and efficient breakage of electric meters. The laser ablation thresholds of the polymethyl methacrylate (PMMA) and the glass material of the liquid crystal display module are first studied. Afterward, we discuss the mechanisms and characteristics of two typical marking methods. When the laser beam is focused on the surface of the PMMA layer, clear black marks form due to laser-induced carbonization. However, low molecular weight organics generate during the processing, which can result in the generation of gas pollution. By utilizing the spot size variation during propagation and the different ablation threshold of PMMA and glass material, laser marking can be realized on the glass surface by passing through the PMMA layer. Clear marking forms due to the resolidification of the glass material while avoiding the generation of debris and gas pollution. Utilizing this interior marking technology for meter breakage can not only avoid the generation of debris and gas pollution but also enable traceability requirements for the entire life cycle of electric meter, which can be used to replace traditional mechanical breakage methods.
