20110199409 | Printing Method and Printer - A printing method and a printer for implementing the printing method are disclosed. When a printhead including a first end and a second end sequentially prints a first area and a second area which are adjacent to each other, the method comprises performing printing by means of the printer by relatively moving locations of the printhead and a print object in such a way that a surface printed by the second end in the first area and a surface printed by the second end in the second area face each other. The printhead rotates around a rotational axis comprising at least one point on the printhead, one end of the printhead, a center of the printhead, or both ends of the printhead. | 08-18-2011 |
20120097927 | Organic Light Emitting Diode Display - An organic light emitting diode (OLED) display may be constructed with a substrate; a first electrode formed on the substrate; a barrier rib formed on the substrate and having an opening exposing the first electrode; an organic emission layer formed on the first electrode; and a second electrode formed on the organic emission layer. The barrier rib includes an isolating groove formed between organic emission layers of neighboring pixels. Accordingly, in the organic light emitting diode (OLED) display, the isolating groove is formed at the barrier rib such that ink is prevented from crossing over the barrier rib and flowing into a neighboring pixel without a hydrophobic surface treatment of the barrier rib. | 04-26-2012 |

20130005211 | DONOR SUBSTRATES, METHODS OF MANUFACTURING DONOR SUBSTRATES AND METHODS OF MANUFACTURING ORGANIC LIGHT EMITTING DISPLAY DEVICES USING DONOR SUBSTRATES - A donor substrate having a plurality of recesses and isolation structures may be provided. The isolation structures may be defined by the recesses. A first electrode is formed on a first substrate. A pixel defining layer may be formed on the first electrode to define a plurality of pixel regions. The donor substrate may be arranged over the first substrate, and a laser induced thermal imaging process may be performed to form a plurality of light emitting layers in the pixel regions. A second electrode may be formed on the pixel defining layer and the light emitting layers. The organic light emitting layers having minute dimensions may be effectively obtained from the donor substrate. The isolation structures may be formed integrally with the substrate, and thus the donor substrate may be easily recycled after the laser induced thermal imaging process. | 01-03-2013 |
