Abstract

A sintering method includes defining a closed pattern having at least one arcuate section. A substance is applied on a substrate along the closed pattern and is sintered along the closed pattern in a first rectilinear direction. The sintering is finished in a second rectilinear direction along the closed pattern. A display device packaging method includes defining a closed pattern having at least one arcuate section. Frit is applied on a substrate of a display device along the closed pattern. A cover plate is provided on the substrate. The frit is sintered along the closed pattern. The sintering is finished in a second rectilinear direction. Then, the cover plate and the substrate of the display device are packaged.

Claims (18)

1. A sintering method comprising:

defining a closed pattern provided with at least one arcuate section;

applying a substance to be sintered on a substrate along the closed pattern; and

sintering the substance along the closed pattern in a first rectilinear direction, and finishing sintering in a second rectilinear direction,

wherein the first rectilinear diction is the same as the second rectilinear direction.

2. The sintering method according to claim 1 , wherein the closed pattern further includes at least one rectilinear section.

3. The sintering method according to claim 2 , wherein the at least one arcuate section is connected to the at least one rectilinear section, and wherein an arcuate angle between the at least one arcuate section and the at least one rectilinear section is larger than 90°.

4. The sintering method according to claim 1 further comprising the step of providing a tangent on the substrate, with the tangent being tangential to the at least one arcuate section, with the tangent including a first end point, a second end point, and a tangent point, with the first rectilinear direction being in a direction from the first end point to the tangent point, and with the second rectilinear direction being in a direction from the tangent point to the second end point.

5. The sintering method according to claim 4 , wherein the tangent is coated with a protective layer to cover the tangent.

6. A display device packaging method comprising the steps of:

defining a closed pattern which has at least one arcuate section;

applying frit on a substrate of a display device along the closed pattern, and providing a cover plate on the substrate;

sintering the frit along the closed pattern in a first rectilinear direction, and finishing the sintering in a second rectilinear direction, the first rectilinear direction being the same as the second rectilinear direction; and

packaging the cover plate and the substrate of the display device with the display device having a shape identical to the closed pattern.

7. The display device packaging method according to claim 6 , wherein the closed pattern further includes at least one rectilinear section.

8. The display device packaging method according to claim 7 , wherein the at least one arcuate section is connected to the at least one rectilinear section, and wherein an arcuate angle between the at least one arcuate section and the at least one rectilinear section is larger than 90°.

9. The display device packaging method according to claim 6 , further comprising the step of providing a tangent on the substrate, with the tangent being tangential to the at least one arcuate section, with the tangent including a first end point, a second end point, and a tangent point, with the first rectilinear direction being in a direction from the first end point to the tangent point, and with the second rectilinear direction being in a direction from the tangent point to the second end point.

10. The display device packaging method according to claim 9 , wherein the tangent is coated with a protective layer to cover the tangent.
