| 20100033805 | ELECTRONIC PAPER DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - An electronic paper display device and a method of manufacturing the electronic paper display device are disclosed. The method in accordance with an embodiment of the present invention includes forming a plurality of partition walls on a lower board, in which the partition walls partition the lower board into cells, disposing a display unit in the cell, and attaching an upper board on an upper part of the plurality of partition walls such that the display unit is covered. This method can adjust a distance between display units and the shape of the display units, and the quantity of disposed display units can be made uniform, whereby the visual quality of the display can be improved by removing spots formed on a screen. | 02-11-2010 |
| 20100047528 | ELECTRONIC PAPER DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF - An electronic paper display device and a method of manufacturing the electronic paper display device are disclosed. The method can include forming a plurality of relievo patterns on a lower board, in which the relievo patterns are formed to be independent and separated from one another, disposing a display unit in between the plurality of relievo patterns, and attaching an upper board on the plurality of relievo patterns such that the display unit is covered. In accordance with an embodiment of the present invention, the method can improve the freedom of disposing the display units by allowing partition walls to form only at areas to fix the display units. | 02-25-2010 |
