Patent ID: 8089497

Claim:
A driving method for a display device including (1) a scan circuit, (2) a signal output circuit, (3) display elements which are arrayed in the form of a two-dimensional matrix having a total of N×M display elements, that is, N display elements juxtaposed in a first direction and M display elements juxtaposed in a second direction different from the first direction, and each of which includes a current-driven light emitting section and a drive circuit, (4) M scan lines coupled to the scan circuit and extended in the first direction, (5) N data lines coupled to the signal output circuit and extended in the second direction, and (6) a power supply, the drive circuit including a writing transistor, a driving transistor, and a capacitor, and in the display element located in the m-th row (where m denotes 1, 2, etc., or M) and the n-th column (where n denotes 1, 2, etc., or N), (A-1) one of the source/drain regions of the driving transistor being connected to the power supply, (A-2) the other source/drain region of the driving transistor being connected to an anode included in the light emitting section, and also connected to one of electrodes of the capacitor in order to thus form a second node, (A-3) the gate electrode of the driving transistor being connected to the other source/drain region of the writing transistor, and also connected to the other electrode of the capacitor in order to thus form a first node, (B-1) one of the source/drain regions of the writing transistor being connected to the n-th data line, and (B-2) the gate electrode of the writing transistor being connected to the m-th scan line, the driving method for the display device comprising the steps of: performing writing processing to apply a video signal to the first node over the data line via the writing transistor with a predetermined driving voltage applied from the power supply to one of the source/drain regions of the driving transistor, wherein the trailing edge of a scanning signal to be applied to the gate electrode of the writing transistor at the writing processing step is inclined; and the luminance characteristic of the display elements connected onto each of the scan lines is controlled by controlling the crest value of the scanning signal, which is applied to the first to M-th scan lines, for each of the scan lines.
