Summary:An encapsulation structure of the display unit and a method of forming the same, mainly use the thin film encapsulation structure to hermetically protect the display unit (such as OLED display unit), that is sealing the display unit by inorganic thin film layer having the characteristics of transparency as well as containing moisture-resistance and oxygen-resistance; buffering the internal and external stresses of the thin film layers and restraining the falling off of the layers caused by the bending stress when forming flexible devices. Meanwhile, the bank features formed by multilayer stack can effectively inhibit the diffusion effect of inorganic coating and the increase of the number of side water retaining walls of thin film device can improve the effect of encapsulation, and the bank structures act as a support of the metal mask during the coating process to prevent the substrate from the damage caused by the metal mask.
