Abstract:
Pixel regions are defined in the surface of a substrate. Partitions are provided between the pixel regions in the surface of the substrate. Each partition includes a lower portion provided on the lower portion and made of an inorganic insulating material and an upper portion of an insulating material having etching properties different from those of the inorganic insulating material of the lower portion. The upper portion overhangs from the side of the lower portion toward the pixel region. A lower electrode is formed on each pixel region. An organic layer containing an organic light-emitting material that emits light when current is injected is formed on the lower electrode. An upper electrode is provided on the organic layer.
Abstract:
A printer having an ink jet head (110) for pressurizing pressurization regions provided in a plurality of pressure chambers to discharge the ink from nozzles in the pressure chambers, wherein an ink reservoir space (130) is defined between a head body (3) and an ink feeder (50), and the ink reservoir space (130) and each pressure chamber are put in communication with each other by an ink feed passage (129) that is opened at one end to the ink reservoir space (130) on the outer surface of the head body (3) and at the other end to each pressure chamber, whereby the ink from the ink feeder (50) can be directly fed into each pressure chamber, while achieving improved print quality by making uniform the feeding of ink into each pressure chamber, in addition to a reduction in size of the ink jet head and an improved degree of integration.
Abstract:
Each pixel (21) contains a plurality of light emitting areas having an organic EL layer (3) and includes light emitting areas (11R, 11G, 11B) corresponding to R, G, B and a plurality of TFT elements (12) arranged for the respective light emitting areas for controlling light emission of each light emitting area. The light emitting areas are arranged in a checkerboard so as to be not in contact with the adjacent light emitting areas. Each pixel (21) is divided into six divisions (22a to 22c, 23a to 23c) and the light emitting areas are arranged in three divisions of the checkerboard (22a to 22c). With this configuration, in a bottom emission type active matrix organic EL display, it is possible to effectively assure a sufficient numerical aperture and realize a pixel arrangement hardly sacrificing the numerical aperture even when increasing fineness. This contributes to suppression of power consumption required for obtaining necessary luminance and reduction in size of the drive circuit and the entire apparatus.
Abstract:
An ink-jet head having a plurality of nozzles for spraying ink fed by an ink supply comprises a main body, which includes a plurality of compartments (112) provided for each nozzle and charged with ink and a plurality of pressurizing parts for applying pressure to the compartments (112) to make the compartments (112) to spray ink from the nozzles. An individual electrode (109) is provided to drive each pressurizing part. The pressurizing parts each have at least one contact (121) connected with an external source of a signal for controlling the pressurizing part. Thin-film wiring patterns (123) for connecting the individual electrodes (109) and the contacts (121) are formed to facilitate connections with the external source and increase productivity and reliability.
Abstract:
A light emitting device comprising a plurality of drive electrodes used for attaining desired light emission wherein the plurality of drive electrodes constitute a passive matrix drive electrode arrangement and at least one drive electrode makes an angle that is not parallel with nor perpendicular to an arbitrary side of the display region on a substrate.
