| 313507000 | With photosensitive layer | 6 |
| 20090128028 | COLOR-STABLE PHOSPHOR CONVERTED LED - A light-emitting device is provided, comprising at least one light-emitting diode ( | 05-21-2009 |
| 20090302759 | ORGANIC LIGHT EMITTING DIODE AND METHOD OF FABRICATING THE SAME - An organic light emitting diode and a method of fabricating the same. The organic light emitting diode includes a substrate, a first electrode on the substrate, emission layers on the first electrode including red, green and blue pixel regions, and a second electrode on the emission layers. The organic light emitting diode further includes an electron transport layer on the emission layers, and an intermediate layer formed by co-depositing metal quinolate and an organic material between at least one of the emission layers and the electron transport layer. The intermediate layer inhibits hole transport and increases a life span of the red pixel region. | 12-10-2009 |
| 20120007501 | DISPLAY DEVICE - A display device is disclosed. The pixels of the display are formed so that a chromaticity range of the red organic emission layer satisfies an NTSC standard if λpr=3.93557E−03 Wr | 01-12-2012 |
| 20120043882 | IMAGE DISPLAY APPARATUS - An image display apparatus includes a rear plate and a face plate. The face plate 11 includes light emitting members spaced from and facing the plurality of electron-emitting devices in an image display region and emitting light responsive to irradiation with electrons, anodes mounted on the light emitting members, partitioning members interposed between the mutually adjacent light emitting members and protruding further than the light emitting members toward the rear plate, first resistance members each located in a portion of the partitioning members and spaced from and facing rear plate and electrically connected to the anodes; and second resistance members each covering a first resistance member and having a volume resistivity larger than that of the first resistance members to expose the first resistance members in the image display, wherein the partitioning member has a groove formed in the portion of the partitioning member opposing the rear plate, and the second resistance member is formed in the groove. | 02-23-2012 |
| 20120062109 | Organic Electroluminescent Device and Method of Fabrication - An organic electroluminescent device comprises an anode; a cathode; a first electroluminescent layer between the anode and the cathode comprising an electron transporting material; and a second electroluminescent layer between the first electroluminescent layer and the anode. The second electroluminescent layer comprises a hole transporting material and an electroluminescent electron trapping material. The first electroluminescent layer may comprises a polymer having an electron transporting material and an electroluminescent material, and may include an optionally electroluminescent hole-transporting material. The electron transporting material and one or both of the hole transporting material of the first electroluminescent layer and the electroluminescent material of the first electroluminescent layer are part of the same molecule or polymer. Preferably, the electron transporting material comprises a plurality of adjacent arylene repeat units. | 03-15-2012 |
