摘要:
A printing system comprises a moving rail, a cliché plate and a substrate positioned on the moving rail, a printing roller that transcribes a pattern material on the substrate by passing through the cliché plate. The printing system further comprises a cleaning unit that cleans the cliché plate.
摘要:
A patterning method and a method for manufacturing an LCD device using the same are disclosed. The patterning method includes preparing a printing plate having concave and convex portions; coating a pattern material in the concave portion of the printing plate; rolling a printing roller on the printing plate to print the pattern material of the concave portion on the printing roller; and rolling the printing roller on a substrate to print the pattern material of the printing roller on the substrate.
摘要:
A printing device system comprises a printing roller that has a blanket adhered to an outer surface thereof. The printing device system further comprises a drying device that dries the blanket of the printing roller.
摘要:
Disclosed is a solvent for printing which comprises a first solvent selected from the group consisting of acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, methanol and mixtures thereof, and a second solvent selected from the group consisting of propylene glycol monomethyl ether acetate (PGMEA), propylene glycol monomethyl ether (PGME), isopropanol, butyl acetate, ethyl-3-ethoxypropionate and mixtures thereof. Further disclosed are a pattern composition for printing comprising the solvent for printing, and a patterning method using the composition. The use of the solvent for printing enables formation of an accurate pattern.
摘要:
A printing apparatus adapted for printing wide line width and narrow line width patterns with one printing plate when fabricating a liquid crystal display device is disclosed. The printing apparatus includes a printing roll having target pattern forming material spread thereon, a printing substrate have at least one pair of adjacent printing plate patterns and at least one barrier rib pattern therebetween, and a target substrate. The printing substrate is configured to receive target pattern forming material from the printing roll and the target substrate is configured to receive target pattern forming material remaining on the printing roll following transfer of target forming material to the printing substrate.
摘要:
A printing device and a printing method using the same is disclosed. An air pocket is formed in a cliché stage to prevent a cleaning solution from permeating into a space between the cliché stage and a cliché plate, thereby preventing a lower surface of the cliché plate from being contaminated. The printing device comprises a cliché stage for fixation of a cliché plate, a plurality of vacuum holes disposed in the cliché stage for providing a vacuum to fix of the cliché plate to the cliché stage; and an air pocket surrounding the plurality of vacuum holes for providing air to minimize permeation of a cleaning solution into a space between the cliché plate and the cliché stage.
摘要:
A printing device system and a patterning method using the same is disclosed, to prevent the volume of blanket from being changed due to the dissolution of solvent included in the pattern material, to thereby realize a precise pattern, in which the printing device system comprises a printing roller having a blanket adhered to an outer surface thereof; and a drying device that dries the blanket of the printing roller.
摘要:
A printing device includes a main body and a plurality of nozzle units on a lower portion of the main body, a plurality of accommodation grooves within the main body and configured to contain a printing material, and a plurality of slits in each nozzle unit and each slit connected to an accommodation groove, so as to coat the printing material onto a printing object. Since the printing device includes a plurality of nozzle units that can individually control the amount of printing material flowing out of the printing device, the amount of printing material can be easily controlled and regulated. A method of using the printing device includes coating a printing roll with the printing material.
摘要:
A printing plate and a method of fabricating an LCD device are disclosed. The printing plate includes convex and concave portions, and a blanket support formed in the concave portion to prevent the bottom of the concave portion from being directly in contact with a pattern material coated on a blanket of a printing roll. The blanket support is additionally formed in the concave portion of the printing plate to prevent the pattern material coated on the blanket of the printing roll from being directly in contact with the bottom of the concave portion. In this case, the pattern material can be prevented from being transferred onto the printing plate in an undesired pattern. As a result, it is possible to form a precise pattern.
