TL;DR: In this paper, a multilayer organic light-emitting device with a guest emitter, tris(2-phenylpyridine) iridium doped in a host 4,4'-N,N'-dicarbazol-biphenyl layer was prepared.
Abstract: Multilayer organic light-emitting devices with phosphorescent guest emitter, tris(2-phenylpyridine) iridium doped in a host 4,4'-N,N'-dicarbazol-biphenyl layer were prepared. The device with the 6.5 wt% guest emitter exhibited external quantum efficiency and power luminous efficiency of 13.7% and 38.3 lm/W, respectively at the luminance of 105 cd/m2 driven at the voltage of 4.0 V and current density of 0.215 mA/cm2. The half decay lifetime under continuous constant-current driving for the initial luminance of 500 cd/m2 was 170 h.

TL;DR: In this paper, the authors developed a barrier film on a plastic substrate and a passivation film on the OLED device itself, which showed good emission characteristics after storage, and its characteristics were almost the same as those of a device fabricated on a glass substrate.
Abstract: Organic light-emitting diodes (OLEDs) displays using plastic substrate have many attractive features. They are ultrathin and light, in addition, it will be realized the flexible display to utilize the flexibility of the substrate. The key issue in achieving such displays is how to protect OLEDs from moisture and oxygen. We developed a barrier film on a plastic substrate and a passivation film on the OLED device itself. As a result, the device showed good emission characteristics after storage, and its characteristics were almost the same as those of a device fabricated on a glass substrate. We also developed a 3-in full-color flexible OLED display.

24 Jul 2003TL;DR: In this article, a method for driving a plasma display panel that provides an improved expression of levels of halftone as well as an improved display quality is presented, where a pixel data writing step for setting discharge cells to either one of non-light emitting cells or light emitting cells in response to pixel data and a light-emission sustaining step for allowing only the aforementioned light- emitting cells to emit light only during a light emission period corresponding to weights assigned to the sub-fields respectively are executed.
Abstract: The object of the invention is to provide a method for driving a plasma display panel that provides an improved expression of levels of halftone as well as an improved display quality. In N sub-fields constituting a display period of one field, when a pixel data writing step for setting discharge cells to either one of non-light-emitting cells or light-emitting cells in response to pixel data and a light-emission sustaining step for allowing only the aforementioned light-emitting cells to emit light only during a light-emission period corresponding to weights assigned to the sub-fields respectively are executed, the light-emission period in the light-emission sustaining step of the respective sub-fields is changed field by field or frame by frame. According to another aspect, the invention allows for carrying out selectively a first drive pattern or a second drive pattern. The first drive pattern is carried out by alternating, field by field (frame by frame) in response to the type of input video signals, first and second light-emission drive sequences which have mutually different ratios of the number of times of light-emissions in the light-emission sustaining step during one field (one frame). The second drive pattern is carried out by alternating, field by field (frame by frame) in response to the type of input video signals, third and fourth light-emission drive sequences which have mutually different ratios of the number of times of light-emissions in the aforementioned light-emission sustaining step.

TL;DR: In this paper, the authors investigated heterojunction organic solar cells composed of different metal phthalocyanines (MPcs, M=Fe, Co, Ni, Cu, and H2)/fullerene (C60) and compared the solar cell characteristics with the field effect hole mobilities (μh) and exciton diffusion length (Lex) of the different MPcs.
Abstract: The authors investigated heterojunction organic solar cells composed of different metal phthalocyanines (MPcs, M=Fe, Co, Ni, Cu, and H2)/fullerene (C60) and compared the solar cell characteristics with the field-effect hole mobilities (μh) and exciton diffusion length (Lex) of the different MPcs. They observed that the short circuit current (JSC) is linearly dependent on the μh of the MPcs, except for ZnPc. They also estimated the Lex of the MPcs by creating a line of best fit using the action spectra of the external quantum efficiency in the solar cells and found that JSC is closely correlated with the Lex of the MPcs.
