  • Patent number: 7570244
    Abstract: Signal lines for supplying signal currents to respective pixel circuits having light emitting elements are arranged. A signal line driving circuit generates, on a signal line, a signal current corresponding to the image data, by switching bit weighting currents output from bit weighting current source circuits provided for respective bits of the image data, using a switch circuit turned on/off dependent on the corresponding bit. Each current source circuit has a function of correcting the level of the bit weighting current output from itself, based on a reference current of the bit weighting current supplied from a reference current line. Therefore, even when the characteristics of TFTs forming respective current source circuits vary widely, variation in signal currents among the signal lines can be suppressed, and unevenness in emission luminance can be suppressed.

    Abstract: A polyolefin resin drawn sheet 4 is laminated on at least one face of a sheet-form core material 6 having a density of 30 to 300 kgf/m3. At this time, a sheet or film 5 made of a bonding synthetic resin or rubber having a flow starting temperature lower than the thermal deformation temperature of the core material 6 and the melting point of the drawn sheet 4 is interposed between the core material 6 and the drawn sheet 4. The resultant stack product is heated to not less than the flow starting temperature of the synthetic resin or the rubber and not more than the thermal deformation temperature of the core material 6 and the melting point of the drawn sheet 4. At the same time of or after the heating, the stack product is pressed to apply a compression strain of 0.01 to 10% to the core material 6.

  • Patent number: 7369125
    Abstract: A current supply circuit providing a data line with a current corresponding to a digital signal composed of data bits includes a current control circuit, a precharge switch and a precharge regulating circuit. The current control circuit responds to control signals reflecting respective data bits to control the amount of current along the data line. The precharge switch precharges the data line to a predetermined voltage prior to current supply. The precharge regulating circuit exchanges with the data line electric charge corresponding to the control signals to move the voltage on the data line closer to a steady voltage corresponding to the data bits. In this way, an analog current corresponding to digital data can be promptly produced.

  • Patent number: 7242378
    Abstract: A current supply circuit includes a bit select circuit selectively providing even-numbered bits or odd-numbered bits of eight bit image data, and supplies a gray-scale current corresponding to the bits provided from the bit select circuit to a pixel. In a one-frame period, a time length for supplying a current corresponding to the even-numbered bits to the light-emitting element is set twice as large as a time length for supplying a current corresponding to the odd-numbered bits. By setting 16 levels of the gray-scale current for four bits, a current-time product of a current passing through the light-emitting element during the one-frame period can be controlled to 256 levels for eight bits. Thereby, an image display device provided at each of the pixels with the light-emitting element can reduce sizes of circuits generating the gray-scale current in accordance with a digital signal.
