Problems solved by technology
[0002] At present, in the packaging technology in the field of display devices, the glass glue between the cover glass and the glass substrate is generally used for sealing. After aligning with the glass substrate, the glass glue is sintered so that the cover glass and the glass substrate are encapsulated. However, the surface contact area between the existing glue-coated Mask and the cover glass is large, and due to the uneven surface of the glue-coated Mask, etc. The reason is that there is a gap between the gluing Mask and the cover glass. During the gluing process, when the scraper is pressed down, the glass glue will penetrate from the gap between the gluing Mask and the cover glass, forming burrs (such as figure 1 As shown), the glass glue on the cover glass forms burrs. During the sintering process aligned with the substrate glass, it is easy to melt the SD layer circuit and cause an open circuit, resulting in poor display

Abstract
The invention relates to the technical field of display, and discloses a glass glue spreading mask and a glue spreader. The glass glue spreading mask comprises a mask body, wherein a plurality of openings are formed in the mask body; at least one part of elastic cushions which are in one-to-one correspondence to the openings are formed in the surface, which is opposite to a substrate, of the maskbody; among each pair of elastic cushions and openings which correspond to each other, the elastic cushions define slot holes which are opposite to the openings and penetrate through the openings; andthe slot holes are matched with the openings to form a glass glue channel for filling glass glue. In the glass glue spreading mask, the elastic cushions can tightly fit to the substrate without gaps,so that a condition that the glass glue leaks burrs in seams during glass glue spreading is avoided, and a condition that burrs are generated by the glass glue formed on the substrate is relieved, and therefore, the problem that a short circuit is caused as an SD-layer circuit is damaged during sintering of the glass glue on the substrate can be effectively relieved, bad display is avoided, and the product yield is increased.
