Method for forming pattern and method for manufacturing liquid crystal display device
View Patent ↗A method of forming a pattern and a manufacturing method of a liquid crystal display includes forming the pattern with a thin thickness by coating a pattern material on a printing roll using a nozzle, removing a surplus portion of the pattern material from the printing roll by using a plate, and transferring the pattern material remaining on the printing roll to a substrate to form the pattern.
1. A method of forming a pattern, the method comprising:
disposing a material on a roll using a nozzle;
removing a first portion of the material using a plate, thereby, leaving a second portion of the material on the roll; and
transferring the second portion from the roll to a substrate to form the pattern,
wherein the material is discontinuously disposed on the roll prior to removing so as to correspond to the pattern formed on the substrate.
2. The method of claim 1 , wherein a diameter of an aperture of the nozzle ranges from 0.1 μm to 100 μm.
3. The method of claim 1 , wherein the nozzle comprises a piezoelectric unit to oscillate a terminus of the nozzle that emits the material.
4. The method of claim 3 , wherein the frequency of the piezoelectric unit ranges from 10 kHz to 30 kHz.
5. The method of claim 3 , wherein a volumetric flow rate of the material ranges from 0.1 μL/s to 100 μL/s.
6. The method of claim 1 , wherein a viscosity of the material ranges from 1 cp to 11 cp.
7. The method of claim 1 , further comprising rotating the roll while disposing the material on the roll.
8. The method of claim 1 , wherein an upper surface of the plate comprises a protrusion and a recess, and
the first portion is separated from the roll and is attached to the plate in response to the roll being rotated on the upper surface of the plate.
9. The method of claim 1 , wherein the pattern is formed in response to the roll being rotated on the substrate.
10. The method of claim 1 , wherein the roll comprises a blanket covering the roll, and the material is disposed on the blanket.
11. A method of manufacturing a liquid crystal display comprising a first substrate and a second substrate comprising a plurality of patterns, the method of forming the plurality of patterns comprising:
disposing a pattern material on a printing roll using a nozzle;
removing a portion of the pattern material using a plate; and
transferring the pattern material remaining on the printing roll to the first and second substrates to form the plurality of patterns,
wherein the material is discontinuously disposed on the roll prior to removing so as to correspond to the plurality of patterns formed on the first and second substrates.
12. A method of forming a pattern, the method comprising:
disposing a material on a roll using a nozzle;
removing a first portion of the material using a plate, thereby, leaving a second portion of the material on the roll; and
transferring the second portion from the roll to a substrate to form the pattern,
wherein the nozzle delivers drops of uniform size and uniform shape of the material to the roll, and
wherein the material is discontinuously disposed on the roll prior to removing so as to correspond to the pattern.
13. The method of claim 12 , wherein a diameter of an aperture of the nozzle ranges from 0.1 μm to 100 μm.
14. The method of claim 12 , wherein the nozzle comprises a piezoelectric unit to oscillate a terminus of the nozzle that emits the material.
15. The method of claim 14 , wherein a frequency of the piezoelectric unit ranges from 10 kHz to 30 kHz.
16. The method of claim 14 , wherein a volumetric flow rate of the material ranges from 0.1 μL/s to 100 μL/s.
17. The method of claim 12 , wherein a viscosity of the material ranges from 1 cp to 11 cp.
18. The method of claim 12 , further comprising rotating the roll while disposing the material on the roll.
19. The method of claim 12 , wherein an upper surface of the plate comprises a protrusion and a recess, and
the first portion is separated from the roll and attached to the plate in response to the roll being rotated on the upper surface of the plate.
20. The method of claim 12 , wherein the pattern is formed in response to the roll being rotated on the substrate.
21. The method of claim 12 , wherein the roll comprises a blanket covering the roll, and the material is disposed on the blanket.
22. The method of claim 12 , wherein the nozzle comprises a peristaltic unit to modulate the delivery of the material from the nozzle.
