摘要： A motor controller is provided which can be reduced in the number of the wirings and power semiconductor devices required while maintaining the function equivalent to or higher than that of the motor controller adopting the existing winding changeover scheme, thereby realizing cost and size reduction and life increase. The motor is made in a structure having motor windings opened at both ends. The one end terminals of phase windings are respectively connected to the output terminals of a first inverter circuit while the other end terminals are respectively connected to the output terminals of a second inverter circuit. During power generation, any one of the inverter circuits is driven on all the phases by means of a same control pulse.

摘要： 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.

摘要： A method of driving a plasma display panel for generating picture or image with high quality while suppressing luminance to a low level in the display in black. One field for image display is composed of at least two different types of subfields first and second subfields. In the first subfield (subfield A), a reset period is provided in which after a priming pulse (Pp) having a voltage value and a pulse width has been applied between X- and Y-row electrodes for causing discharge to occur in all of pixels, then the voltage applied between both the electrodes is set to zero for erasing wall charge after the discharge of all of the pixels, while in the second subfield (subfield B), a reset period is provided in which an erasing pulse (Ep) having a voltage value and a pulse width for causing only the pixels discharged in the preceding subfield to be discharged has been applied for allowing only the pixels discharged in the preceding subfield to be discharged, the wall charge is erased by setting to zero the voltage applied between the X- and Y-row electrodes.
