Method for cutting liquid crystal display panel wherein removing a particular portion of the seal line
View Patent ↗A method for cutting a liquid crystal display panel includes providing first and second mother substrates, forming a scribing line on the first and second mother substrates, removing a portion of a seal line being overlapped with the scribing line, the seal line formed on one of the first and second mother substrates, and dividing the first and second mother substrates into a plurality of unit liquid crystal display panels along the scribing line.
1. A method for cutting a liquid crystal display panel, comprising:
providing first and second mother substrates;
forming a scribing line on the first and second mother substrates;
removing a portion of a seal line being overlapped with the scribing line, the seal line formed on one of the first and second mother substrates; and
dividing the first and second mother substrates into a plurality of unit liquid crystal display panels along the scribing line.
2. The method of claim 1 , wherein removing the portion of the seal line includes using a laser to remove the portion of the seal line being overlapped with the scribing line.
3. The method of claim 1 , wherein providing the first and second mother substrates comprises:
forming a plurality of color filter substrates on the first mother substrate;
forming a plurality of array substrates on the second mother substrate;
forming the seal line with a sealant on one of the first and the second mother substrates; and
attaching the first and second mother substrates by hardening the seal line.
4. The method of claim 1 , wherein forming the scribing line includes using a cutting wheel.
5. The method of claim 4 , wherein the cutting wheel includes a diamond.
6. The method of claim 4 , wherein a laser is installed at the front of the cutting wheel.
7. The method of claim 1 , wherein forming the scribing line includes using at least two cutting wheels.
8. The method of claim 7 , wherein the cutting wheel includes a diamond.
9. The method of claim 7 , wherein a laser is installed at the front of one of the cutting wheels.
10. A method for cutting a liquid crystal display panel, comprising:
attaching first and second mother substrates to each other;
forming a first prearranged cut line on the first and second mother substrates, a portion of a seal line between the first and the second mother substrates being overlapped with the first prearranged cut line is removed; and
forming a second prearranged cut line on the first and second mother substrates, the portion of the seal line overlapped with the second prearranged cut line is removed.
11. The method of claim 10 , further comprising:
cutting the first and second mother substrates by applying a pressure to at least one portion of the first prearranged cut line through a roll to form a plurality of unit liquid crystal display panels.
12. The method of claim 10 , further comprising:
cutting the first and second mother substrates by applying a pressure to at least one portion of the second prearranged cut line through a roll to form a plurality of unit liquid crystal display panels.
13. The method of claim 10 , wherein the portion of the seal line is removed using a laser.
14. The method of claim 10 , wherein the first prearranged cut line and the second prearranged cut line are formed at substantially the same time using at least two cutting wheels.
15. The method of claim 10 , wherein forming the first prearranged cut line includes forming the first prearranged cut line on an outer surface of the first mother substrate and forming the second prearranged cut line includes forming the second prearranged cut line on an outer surface of the second mother substrate.
