Abstract
Provided are a roller apparatus, a printing method and a method of fabricating an LCD device using the same, which can minimize the number of processes and a printing defect. In the printing method, first patterns are formed on a blanket. The first patterns have different surface energy from that of the blanket, and the blanket is formed around a roller. The roller is rotated and a printing material is dropped to form second patterns on the blanket between the first patterns. The second patterns are transferred from the roller onto a substrate.
Claims10
A printing method comprising:
- forming first patterns of a first material on a blanket of a second material which is flat, the first patterns having different surface energy from the blanket;
- attaching the blanket around a roller, wherein the blanket covering an entire circumference surface of the roller, wherein ends of the blanket are connected by using an adhering unit;
- rotating the roller and dropping a printing material to form second patterns on the blanket between the first patterns, the roller being vibrated by a vibrating motor to cause the printing material on the first patterns to flow toward the blanket so as to form the second patterns on the blanket between the first patterns;
- and
- transferring the second patterns onto a substrate,
- wherein the first patterns have lower surface energy than the blanket, and
- wherein the second patterns have greater thickness than the first patterns as measured perpendicularly from a surface of the blanket.
A roller apparatus comprising:
- a roller;
- a blanket of a first material having a first surface energy, the blanket covering an entire circumference surface of the roller and being attached around the roller;
- patterns of a second material on the blanket, the patterns having a second surface energy different from the first surface energy;
- and
- a vibrating motor vibrating the roller to cause a printing material to flow away from the patterns toward the blanket,
- wherein the patterns have lower surface energy than the blanket, and
- wherein ends of the blanket are connected by using an adhering unit.
