摘要： A power converting unit supplies a predetermined current to each of light-emitting elements by controlling a duty ratio of a semiconductor switching element. A light-emitting-element selecting unit sequentially selects a light-emitting element to be supplied with the current from the power converting unit. A duty-ratio control unit controls the duty ratio of the semiconductor switching element based on a value obtained by multiplying a gain by a difference between an output current of the power converting unit and a target current. A gain selecting unit changes the gain according to selected light-emitting element.

摘要： The main electric power source is connected to a lower-voltage side of a DC/DC converter by a first switch, and an electrical double-layer capacitor and a regulator circuit is connected to a higher-voltage side of the DC/DC converter. In addition, permanent magnets are disposed on a rotor so as to generate a magnetic field that is in a reverse direction to excitation by a field coil inside a claw-shaped magnetic pole portion of the rotor. A power supply control circuit controls opening and closing of the first switch so as to be in an open state when the engine is at rest, and so as to be set to a connected state after the regulator circuit is operated to make the alternator generate electric power to precharge the electrical double-layer capacitor after the engine is started.

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 display current of a whole gray scale range according to a display signal of four bits is produced from a sum of output currents of an analog current supply circuit producing a first output current according to lower data bits and two digital current supply circuits operating in accordance with corresponding data bits to execute or stop generation of second and third output currents according to higher data bits. The analog current supply circuit has a calibration function of compensating for output current variations due to transistor characteristics at one point in a control range of the first output current. A display device with light-emitting elements can accurately generate a display current for gray-scale expression without imposing an excessive load on a manufacturing process while suppressing circuit footprint.
