  • Publication number: 20050051817
    Abstract: A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

  • Publication number: 20050041185
    Abstract: A liquid crystal display device having a liquid crystal display panel, where a liquid crystal layer is inserted as to be sandwiched between a pair of substrates, and which is provided with polarizers on opposite sides of the liquid crystal layer with the substrates residing between the polarizers, in which a light reflecting metal layer is formed on the inner surface of the substrate on a display surface, and an ?/4 retardation film is arranged between the substrate and the polarizer to serve as light reflection preventing means for the purpose of preventing the light reflected by the metal layer from outputting from the polarizer toward the display surface even if outside light is reflected by the metal layer. According to the present invention, an inexpensive liquid crystal display device is thereby obtained, where the diminution of contrast in the display due to the reflection of outside light by a black matrix is reduced.

  • Patent number: 5357384
    Abstract: A flexible magnetic disk drive is disclosed which has a data transducer mounted to a pivotal support beam for movement into and out of data transfer contact with the disk. When the transducer is retracted away from the disk, the support beam butts on the top plate of the disk drive casing for the reduction of the thickness of the disk drive, that is, its dimension in a direction perpendicular to the plane of the disk. A stepper motor is provided for moving the transducer across data tracks on the disk in response to external stepping pulses from a host system and to internal stepping pulses for recalibration. The application of such stepping pulses to a stepper motor control circuit is prevented when the disk is not loaded in the disk drive, in order to avoid the movement of the support beam in sliding contact with the top plate.
