PATTERN FORMING DEVICE OF A FLAT DISPLAY DEVICE AND A PATTERN FORMING METHOD USING THE PATTERN FORMING DEVICE, PARTICULARLY RELATED TO EMPLOYING UV HARDENING OF INK COATING
PATTERN FORMING DEVICE OF A FLAT DISPLAY DEVICE AND A PATTERN FORMING METHOD USING THE PATTERN FORMING DEVICE, PARTICULARLY RELATED TO EMPLOYING UV HARDENING OF INK COATING
PURPOSE: A pattern forming device of a flat display device and a pattern forming method using the pattern forming device are provided to perform UV hardening after coating ink which includes a photoinitiator to maintain a proper viscosity value during offset, thereby preventing pattern deterioration.;CONSTITUTION: Micro-patterns are formed on a substrate by using a reverse offset printing method. A blanket roll(10) has a rotatable roll frame(12) and a blanket for providing an ink coating surface by surrounding the roll frame. A slit coater sprays ink(2) to the blanket roll which is rotating, and coats the blanket with ink. An UV irradiator irradiates UV rays on the coated ink to harden the ink, and controls a viscosity value of the coated ink. A printing plate(40) comprises plural convex units and concave units.;COPYRIGHT KIPO 2010
