くしている。FIG. 1 shows a matrix driving method according to the principle of the present invention. A circuit configuration is shown in FIG. 1A, and signal electrodes 12 and 14 are connected to the scanning electrode 10 via light emitting elements A and B, respectively. When the light emitting elements A and B display the same data, the driving timing of one display cycle of the elements A and B is shown in FIGS. 1B, 1C and 1D, that is, the element A , B are shifted in timing to reduce the period in which the elements A and B simultaneously emit light.

が減少する理由について説明する。According to the driving timings shown in FIGS. 1B, 1C and 1D, the current i flowing through the scan electrode 10 is reduced, and as a result, the power consumption is reduced. Here, the reason why the power consumption is reduced will be described.
【００１０】走査電極１０での瞬時消費電力Ｐは、次の

しても、電流の流れる時間は２倍になるので、結局、消
費電力は１／２である（図１（Ｂ）（Ｃ）の場合）。The instantaneous power consumption P at the scan electrode 10 is obtained by the following equation. P = i 2 × R (i: scan electrode current in a certain portion, R; scan electrode resistance in a certain portion) That is, if the instantaneous current decreases to 1/2, the instantaneous power consumption becomes 1/4. Become. Note that even if the instantaneous current is reduced to 1/2, the current flow time is doubled, so the power consumption is eventually 1/2 (in the case of FIGS. 1B and 1C).

明による消費電力減少の効果は大きい。When displaying halftones on the display device, it is possible to reduce power consumption by reducing the number of light emitting elements that simultaneously emit light for one scanning electrode. When displaying,
The effect of reducing power consumption is small. However, in the normal case, the possibility of displaying halftones is higher than the possibility of displaying the maximum brightness on the display device, so that the effect of reducing power consumption according to the present invention is large as a whole.

Here, in the present invention, since the signal voltage is applied to the adjacent signal electrodes 30 to 30 connected to the one common scan electrode 28 with a timing shift within one horizontal scanning period, the peak current of the scan electrode 28 is applied. Can be reduced. In addition, as a configuration in which the signal voltage is applied to the signal electrodes 30 to 30 at a different timing, for example, the X drivers 20 apply modulators 20a to 20a that apply the signal voltage to the signal electrodes 30 to 30, and the modulators 20a to 20a. It is conceivable to include the counter 20b for controlling the timing of 20a, and to operate each of the modulators 20a to 20a with the counter 20b using the horizontal synchronizing signal as a reference and shifting the counting time from the horizontal synchronizing signal.
