Method of manufacturing a display panel with ink recovery
View Patent ↗An apparatus for manufacturing a display panel includes a printing plate having a plurality of recesses formed on its surface and a hole formed at at least one end thereof, a transfer roller for receiving ink injected in the recesses, a supporting plate for supporting a substrate thereon, wherein the ink from the transfer roller is transferred onto the substrate according to a rotation of the roller, and an ink re-using unit positioned in the hole. Productivity can be improved by reducing a fabrication cost by provision of the ink re-using unit to re-use ink.
1. A method for manufacturing a display panel, comprising:
depositing ink on a printing plate including a plurality of recesses formed on a surface thereof and holes formed at both ends thereof;
depositing the ink that has been deposited on the printing plate into the recesses by using blades;
storing remaining ink in a first hole positioned at a first end of the printing plate;
transferring the ink from the recesses to a transfer roller;
lifting an ink re-using unit installed at the first hole where the remaining ink is stored to position the remaining ink on the first end of the printing plate; and
depositing the remaining ink into the recesses by using the blades.
2. The method of claim 1 , further comprising transferring the ink from the transfer roller to a substrate.
3. The method of claim 1 , further comprising:
depositing the remaining ink into the recesses and then storing further remaining ink in a second hole positioned at a second end of the printing plate;
transferring the remaining ink from the printing plate to the transfer roller; and
lifting an ink re-using unit installed at the second hole where the further remaining ink is stored to position the further remaining ink on the second end of the printing plate.
