專利摘要(中)
A micro-droplet ejection apparatus includes a substrate, a droplet-ejecting layer, and a plurality of bubble generators. A liquid storage space is formed between the substrate and the droplet-ejecting layer. The liquid storage space has no spacer connecting the substrate and the droplet-ejecting layer. That is, the liquid storage space has no individual chambers. The droplet-ejecting layer has a plurality of through holes arranged in an array, and each through hole is used as a nozzle for pushing out ink. The plurality of bubble generators is disposed above the substrate, and corresponds to and is disposed under the through holes. The bubble generators on two sides of a designated bubble generator generate at least one limit bubble, limiting the growth of a main bubble generated by the designated bubble generator.
