摘要:
In an apparatus and a method for the printing of spacers in a pattern on substrates of display panels, a printer head includes a plurality of nozzle holes. Each printer head includes a nozzle group having a plurality of nozzle holes. A nozzle group may be selected by the conduction wirings on the vibration membrane and top plate sandwiching the piezoelectric actuators. To print complex patterns on the substrate a plurality of printer head sets, a plurality of printer heads in a line, can be arranged in various configurations.

An apparatus for printing spacers on a substrate of an LCD includes a spacer supply roller having a plurality of recesses formed in its exterior surface. A plurality of uniform volumes of an ink containing the spacers is loaded into the recesses and then transferred from the supply roller onto a transfer belt that is arranged to move tangentially with respect to the supply roller by means of a transfer roller and an auxiliary roller. The LCD substrate is then moved tangentially with respect to the moving transfer belt such that the ink volumes on the transfer belt are transferred onto the substrate at selected locations thereon. The continuously rotating components of the apparatus enable it to accommodate LCD panels of any size without the need for large spacer supply substrates and transfer rollers and prevent the inadvertent deposition of multiple layers of spacers on the substrate.

A spacer-printing apparatus includes a printing roller and a moving part. The printing roller has opposite edges connected by a curved surface and spacers are attached to the curved surface. The moving part is connected with the printing roller and respectively and alternately moves opposite edges up and down. The printing roller has a shape of a portion of cylinder, so that a radius is increased without the increase in volume and weight thereof.

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.

The present invention discloses an alignment substrate that includes a base substrate and an alignment layer arranged on the base substrate. A plurality of unit pixels is defined in the base substrate. The alignment layer includes at least two sub-alignment portions dividing the unit pixel into at least two domains. Each sub-alignment portion is arranged in a different domain of the at least two domains and is aligned to have a different pretilt direction from the other sub-alignment portions.
