Abstract
The present disclosure relates to the field of display technology, and in particular relates to a light shielding structure and a laser device. The light shielding structure comprises a first light shielding plate group and a second light shielding plate group, each of the first light shielding plate group and the second light shielding plate group comprises at least one light shielding plate, and the at least one light shielding plate can be moved relatively for forming at least two light transmitting regions. The light shielding structure can realize partial scanning of multiple target regions at a time, thereby saving production time, increasing production efficiency, saving water and electricity and other resources, and prolonging the laser lifetime.
