摘要： A display device includes a display unit, a horizontal drive circuit, and a vertical drive circuit, the display unit including pixels in a matrix formation, as well as respective signal lines and scan lines via which the drive circuits drive the pixels. Each pixel includes a light-emitting element, a hold capacitor, a write transistor, and a drive transistor. Mobility fluctuations in the drive transistor are compensated for by successively setting the voltage of the signal line to an intermediate voltage and to a tone voltage. In addition, the intermediate voltage is varied in accordance with the tone voltage as well as with the distance from the input terminal of a write signal to a respective pixel. The device thereby compensates for mobility fluctuations in the drive transistor and prevents shading due to irregularities in the waveform of the write signal.

摘要： A display apparatus employs a pixel array section including pixel circuits forming a matrix, signal lines as columns, scan lines as rows and power-supply lines, and driving sections. The driving sections are a signal selector, a write scanner and a drive scanner. The signal selector provides an electric potential representing a gradation or a predetermined reference electric potential. The write scanner provides a control signal. The drive scanner provides a power-supply voltage changing the electric potential from high to low. The drive scanner drives adjacent power-supply lines as a group. The number of lines as a group is determined in advance. The drive scanner switches a power-supply voltage from high to low and vice versa, and applies the voltage to groups by shifting the phase from group to group. The voltage is supplied to a group at the same phase and switched the electric potential.
