| 20090284570 | PRINTER HEAD AND PRINTING METHOD HAVING THE SAME - 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. | 11-19-2009 |
| 20100309422 | DISPLAY PANEL AND METHOD OF MANUFACTURING THE SAME - A display panel includes a first substrate, a second substrate, a liquid crystal layer, a seal line and an outer spacer. The first substrate includes a display area on which a plurality of thin film transistors are formed, and a peripheral area surrounding the display area. The second substrate is opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. The seal line is formed between the first substrate and the second substrate in the peripheral area to confine the liquid crystal between the first and second substrates. The outer spacers are disposed in the peripheral area, and inwardly spaced apart from the seal line by a separation distance thereby preventing liquid crystal from being polluted by particles of an uncured seal line during manufacturing. | 12-09-2010 |

A plurality of pixels are arranged in a matrix defined by the gate lines and the data lines, and alignment directions of the first alignment layer and the second alignment layer in a first pixel are different than alignment directions in a neighboring pixel. | 11-19-2009 |
| 20100020281 | LIQUID CRYSTAL DISPLAY AND PANEL THEREOF - A liquid crystal panel according to an exemplary embodiment of the present invention includes a substrate, and a pixel electrode arranged on the substrate. The pixel electrode includes a first subpixel electrode and a second subpixel electrode separated from each other, and the second subpixel electrode includes a first electrode part disposed above the first subpixel electrode and a second electrode part disposed below the first subpixel electrode and connected to the first electrode part. At least one first notch is arranged on at least one edge of the first subpixel electrode or the second subpixel electrode. | 01-28-2010 |
| 20100034989 | ALIGNMENT SUBSTRATE, METHOD OF MANUFACTURING THE ALIGNMENT SUBSTRATE AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE ALIGNMENT SUBSTRATE - An alignment substrate includes a substrate and an alignment layer. The substrate includes a plurality of unit pixel areas. Each of the unit pixel areas includes a plurality of sub-pixel areas arranged in a matrix configuration. The alignment layer is on the substrate and has polymer chains protruding from a surface of the alignment layer. The alignment layer has a plurality of alignment vectors in which the polymer chains are pretilted according to the sub-pixel areas. The alignment vectors corresponding to adjacent sub-pixel areas point in different directions from each other. | 02-11-2010 |
| 20100157223 | ALIGNMENT SUBSTRATE FOR ALIGNING LIQUID CRYSTAL MOLECULES, LIQUID CRYSTAL DISPLAY PANEL HAVING THE SAME, AND METHOD OF MANUFACTURING THE ALIGNMENT SUBSTRATE - 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. | 06-24-2010 |
| 20110085124 | PRINTING BEAD SPACERS ON FLAT PANEL DISPLAY SUBSTRATES - An apparatus for printing bead spacers on a substrate of an LCD panel includes a head unit for spraying a plurality of bead spacer groups on the substrate, a transfer unit for transferring the head unit, and a supply unit for supplying the bead spacers to the head unit. Each of the bead spacer groups includes a plurality of bead spacers, and the sizes of the respective spacers of at least two of the spacer groups are different from each other. The invention enables a cell gap of a substantially uniform thickness to be created and maintained in the panel, prevents the occurrence of smear failures in the panel, and increases the allowable tolerance in the amount of liquid crystal material needed to fill the panel correctly. | 04-14-2011 |
