    Abstract: An apparatus for jetting an alignment agent includes a jetting head having a jetting hole, an alignment agent externally provided onto a substrate and a viscosity controlling part controlling a viscosity of the alignment agent stored in the jetting head to facilitate jetting of the alignment agent. The alignment agent is jetted to the substrate through the jetting hole. The apparatus improves the efficiency of jetting the alignment agent.

    Abstract: An inkjet method of printing an alignment layer is presented. The method entails depositing drops of an alignment liquid on a substrate while moving a plurality of inkjet heads and/or the substrate relative to each other to form a first dropping line on the substrate. The method also entails rotating a printing stage on which the substrate is mounted, and depositing drops of the alignment liquid on the substrate after forming the fist dropping line to form a second dropping line. Since the printing stage is elevated and rotated, the drops of the alignment liquid are easily deposited in a grid pattern to decrease the space between adjacent drops. If desired, drops may be skipped to avoid depositing the alignment liquid multiple times on the same location on the substrate. With this method, the planarization time of the alignment layers is shortened.

    Abstract translation: 提出了一种印刷取向层的喷墨方法。 该方法需要在衬底上沉积定向液体的液滴，同时相对于彼此移动多个喷墨头和/或衬底以在衬底上形成第一滴落线。 该方法还需要旋转其上安装有基底的印刷阶段，并且在形成第一滴下线之后将定向液体的液滴沉积在基板上以形成第二滴下线。 由于印刷阶段升高并旋转，所以对准液体的液滴容易以网格图案沉积，以减小相邻液滴之间的空间。 如果需要，可以跳过液滴，以避免在对准液体多次沉积在基板上的相同位置上。 通过这种方法，缩短了取向层的平坦化时间。

    Abstract: A piezoelectric unit includes a first piezoelectric member having a tubular shape, a second piezoelectric member inserted into a first opening of the first piezoelectric member, and a voltage applying member applying a driving voltage to the first and second piezoelectric members. An orifice plate includes a body through which first nozzle openings corresponding to the first piezoelectric member and second nozzle openings corresponding to the second piezoelectric member are formed. An elastic member is disposed between the first and second nozzle openings and the piezoelectric unit. A shape of the elastic member is changed in accordance with a changed shape of the piezoelectric unit for jetting ink through the first and second nozzle openings. Thus, a nozzle pitch of a printer head may be reduced.
