Abstract: A mask assembly and manufacturing method thereof are provided. The mask assembly includes: a frame, a first mask and a second mask stacked on the frame. The second mask has at least one evaporation region with each being provided with a plurality of evaporation holes having the same shape. The first mask includes a plurality of cross-arranged sub-masks defining at least one open region. The at least one open region is in one-to-one correspondence to the at least one evaporation region, and includes at least one irregular open region. An orthographic projection of each irregular open region on the second mask is located in a corresponding evaporation region. With the mask assembly, the phenomenon of poor color-mixing during evaporation due to the uneven surface of the second mask can be avoided when the irregular display panel is manufactured, and the display reliability of the manufactured display panel can be improved.

Abstract: The embodiments of the present invention provide a packaging structure for OLED device, packaging method and electronic equipment. According to the embodiments of the invention, an anaerobic sealant is applied in the OLED packaging process as a packaging material. Since anaerobic sealant can be cured at room temperature without heat curing or UV curing, the technological process can be simplified, saving the cost. Meanwhile, the OLED process per se should be performed in a vacuum or inert gas environment (i.e., an anaerobic environment), which is advantageous for applying the anaerobic sealant; therefore no more investment is required, and the cost is saved. Moreover, the bonding strength of the cured anaerobic sealant is relatively strong, thus the sealed bonding between the cover plate and the substrate can be realized without an additional dam coating process, simplifying the technological process.
