  • Publication number: 20070033897
    Abstract: An apparatus for arranging a spacer includes a substrate, a roller, and an adhesion unit. The substrate includes a recessed portion. A spacer, which maintains a cell gap of a display panel and has an adhesive member formed thereon, is received in the recessed portion. The roller corresponds to the spacer. The roller makes contact with an exposed portion of the adhesive member. The adhesion unit provides for an adhesive strength between the exposed portion of the adhesive member and the roller that exceeds an adhesive strength between the received portion of the adhesive member and the recessed portion of the substrate so that the spacer may be printed on the roller. Therefore, a cell gap uniformity of a display device may be improved.

  • Publication number: 20070009192
    Abstract: 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.

  • Publication number: 20060151727
    Abstract: A system for determining the amount of LC that is dropped on a display panel is presented. The system can adjust the amount of the LC to be dropped based on a real-time feedback on the amount of LC that is currently being dropped. The amount of LC that is being dropped is detected by utilizing a light source and a CCD camera. Because LC is not consumed wastefully and the detection interval is shortened with this system, the amount of LC that is dropped can be controlled more accurately and manufacturing cost is reduced.
