Claims12
A display substrate, comprising a display region and a sealant coating region provided outside the display region, wherein the sealant coating region is provided with a groove to limit a sealant;
- and
- wherein the groove is provided in the sealant coating region and forms a rectangular moat surrounding the display region, an inner edge of the rectangular moat is connected end to end to form a closed rectangle surrounding the display region of the display substrate, and an outer edge of the rectangular moat includes a plurality of openings for injecting the sealant into the rectangular moat;
- wherein the outer edge is divided into multiple discontinuous parts by the openings;
- wherein, the sealant coating comprises two nozzles, and the two nozzles are perpendicular to each other, and a position of the nozzles corresponds to a position of the openings of the groove, and a valve is provided in the nozzle for controlling the sealant injection.
A manufacturing method of a display substrate, wherein the display substrate comprises a display region and a sealant coating region provided outside the display region, and the manufacturing method comprises a step of forming a groove in the sealant coating region of the display substrate to limit sealant,
- wherein the groove is provided in the sealant coating region and forms a rectangular moat surrounding the display region, an inner edge of the rectangular moat is connected end to end to form a closed rectangle surrounding the display region of the display substrate, and an outer edge of the rectangular moat includes a plurality of openings for injecting the sealant into the rectangular moat;
- wherein the outer edge is divided into multiple discontinuous parts by the openings;
- wherein, the sealant coating comprises two nozzles, and the two nozzles are perpendicular to each other, and a position of the nozzles corresponds to a position of the openings of the groove, and a valve is provided in the nozzle for controlling the sealant injection.
