Description

Technical Field

[0001] The present application relates to the field of Mini LED security technology, and in particular to a Mini LED vacuum air bag film vacuum cavity. Background Art

[0002] In the prior art, Mini Led adopts roller bonding. During the bonding process, since the Mini Led lamp beads protrude from the substrate, the lamp beads are subjected to lateral bonding pressure during the roller bonding process, resulting in damage to the lamp bead welding circuit, thereby affecting the bonding yield; the vacuum bonding upper cavity adopts a hard pressing plate, and the Mini Led lamp beads are crushed during the bonding process, thereby affecting the bonding yield; the use of a hard pressing plate has extremely high requirements for the flatness of the upper and lower products. If the product is slightly tilted, it will cause destructive damage to the product, and has high requirements for flatness, uneven distribution of bonding pressure and other defects.
