ース信号を必要とし、６４０Ｘ４００ドツトの表示装置
では、６４０Ｘ２００ドツトの表示装置のインターフェ
ース信号では駆動することができないという欠点があっ
た。In the conventional display devices described above, for example, a 640×400 dot display device can only display in a 640×400 line mode, and a 640×200 dot display device can only display in a 640×200 line mode. Therefore, a dedicated interface signal is required for each, and a 640x400 dot display device cannot be driven with the interface signals of a 640x200 dot display device.

方式と、複数電極走査方式の切換が可能であるという相
違点を有する。In contrast to the conventional display device described above, the present invention has, in addition to the conventional driving method, a scanning function of sequentially selecting Y electrodes (scanning electrodes) for each plurality of electrodes. The difference is that the electrode scanning method can be switched.

、Ｙ５．Ｙ６、続いて、Ｙ７．Ｙ８へと順次選択してい
く走査方式である。This multiple electrode scanning method means, for example, when scanning Y electrodes (scanning electrodes), first, Yl and Y2 are simultaneously selected, and after the selection period ends, the next two electrodes Y3 and Y4 are simultaneously selected, and then Y5 ．． Y6, then Y7. This is a scanning method that sequentially selects Y8.
本発明の表示装置は、単電極走査方式と、複数電極走査
方式を切換える表示素子駆動回路の制御回路を有してい
る。The display device of the present invention includes a control circuit for a display element drive circuit that switches between a single electrode scanning method and a multiple electrode scanning method.

and a display mode switching switch SW1, the X electrode drive circuit 2 operates upon receiving the X electrode control signal 7 from the drive control circuit 1, and the Y odd number electrode drive circuit 3 and the Y even number electrode drive circuit 4. It operates by receiving a data signal 8, a clock signal 9, and a clear signal 6 from the drive control circuit 1 via a display mode switching game (10.11).

方式が切換られていることになる。The shift register inside the Y-odd electrode and Y-even electrode drive circuit performs a shift operation at the rising edge of the clock signal 9, and as shown in FIG. A clear signal 6 is supplied to Y electrode drive circuits 3 and 4. When SWI is on, the Y electrode group (scanning electrode group) of the display panel 5
A diagram showing the drive waveforms applied to Y1 to Y4 is shown in part a of FIG. At this time, Y1~Y
It can be seen that the drive waveforms VYI to VY4 applied to VY4 are sequentially selected for each electrode, with the pulse waveforms shifting in order from VYI. When SWI is switched from on to off, the clear signal 6 becomes Y1 because the supply to the Y electrode drive circuits 3 and 4 is cut off by game) 10.11.
The drive waveform of ~Y4 is the part b (V'YI~V'
As shown in Y4), Yl and Y2 are selected at the same time,
Subsequently, it can be seen that there is a simultaneous shift to Y3° and Y4. That is, when SWI is on, single electrode scanning method,
When it is off, it becomes a 2-electrode scanning method, and these 2 electrodes are scanned by SWI.
This means that the method has been switched.

In a display device equipped with a display element with a display capacity of 400 dots, if the 400 dot side is used as the scanning electrode, single electrode scanning will display 640 x 400 lines, 2 electrode scanning will display 640 x 200 lines, and 4 electrode scanning will display 640 x 200 lines. This has the effect of realizing multiple display modes such as 640 x 100 line display.
