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 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.

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.
