Abstract
A display device comprises pixels PX each of which has one of different luminosity characteristics, signal line blocks each including a preset number of signal lines X connected to the pixels PX having a common one of the luminosity characteristics, and a signal line driving circuit which drives the signal lines X according to a video signal. Particularly, the signal line driving circuit includes a selection circuit which sequentially selects the signal line blocks in an effective picture period of the video signal and an external driving unit which drives the preset number of signal lines included in the signal line block selected by the selection circuit.

A display device comprising:
- a plurality of pixels each of which has one of different luminosity characteristics;
- a plurality of signal line blocks each including a preset number of signal lines connected to said pixels having a common one of the luminosity characteristics;
- and
- a signal line driving circuit which drives said signal lines according to a video signal, said signal line driving circuit including a selection circuit which sequentially selects the signal line blocks in an effective picture period of the video signal and a driving unit which drives the preset number of signal lines included in the signal line block selected by the selection circuit.
A display device comprising:
- a display section in which at least first pixels of a first luminosity characteristic and second pixels of a second luminosity characteristic are arranged in a matrix form;
- and
- a driving circuit which drives the display section;
- wherein each pixel has a signal line, a scanning line, a switching element connected to said signal line and said scanning line, a capacitance element connected to said switching element, a drive element which control a current according to a voltage held in said capacitance element, and a luminous element connected to said drive element,
- said driving circuit includes a reference gradation voltage generating circuit which generates a group of reference gradation voltages, a signal line driving circuit which generates a signal voltage corresponding to the reference gradation voltage selected based on an input digital signal and supplies the signal voltage to said signal line, and a scanning line driving circuit which supplies a scanning signal to said scanning line,
- said reference gradation voltage generating circuit is configured to alternately generate the reference gradation voltages for said first pixel and the reference gradation voltages for the second pixel by resistive voltage division using a different voltage dividing ratio changed in time sequence.
