Abstract
A mask and an encapsulating method of a display panel are provided. The mask is configured to encapsulating the display substrate. The display substrate includes a display area, a bonding area, and a notch. The mask includes an opening area and a non-opening area. A size of the mask is determined by a size of the used display substrate. A corresponding size of the display substrate adapts the mask having the corresponding size. The present disclosure can effectively prevent line damage and also improve substrate yield.
Claims4
An encapsulating method of a display panel, comprising:
- in a substrate evaporation coating step S1, coating by evaporation a display substrate;
- in a first mask installation step S2, aligning a first mask with the display substrate and attaching the first mask onto the display substrate, wherein the first mask comprises an opening area and a non-opening area, wherein the opening area comprises a first short border and a second short border arranged opposite each other, and wherein the non-opening area comprises a first shield plate protruding from a central section of the first short border of the opening area;
- and a second shield plate protruding from a central section of the second short border of the opening area;
- in a first inorganic encapsulation layer formation step S3, forming a first inorganic encapsulation layer on the display substrate through the opening area of the first mask;
- in a first mask removal step S4, removing the first mask;
- in an organic encapsulation layer formation step S5, spraying an organic material on the display substrate, wherein the organic material is cured under ultraviolet irradiation to form an organic encapsulation layer;
- in a second mask installation step S6, aligning a second mask with the display substrate and attaching the second mask onto the display substrate, wherein the second mask comprises another opening area and another non-opening area, wherein the opening area comprises another first short border and another second short border arranged opposite each other, and wherein the non-opening area comprises:
- another first shield plate protruding from a central section of the first short border of the opening area;
- and another second shield plate protruding from a connecting section of the second short border and one of long borders of the opening area;
- in a second inorganic encapsulation layer formation step S7, forming a second inorganic encapsulation layer on the display substrate through the opening area of the second mask;
- in a second mask removal step S8, removing the second mask.
