Nondispersive drive
After resetting, nondispersive drive will be preset in 4 gradation indications.
In case the B/W indication is selected after resetting, dispersive drive will be preset.
Dispersive drive and nondispersive drive are the LCD drive methods characteristic to the MLS drive.
The S1D15E06 Series is making 4 line MLS drive and, 4 times higher period selection voltage than that of the period
being used for indication of 1 line in an ordinary drive (in case of 132 line indication, the period of 1/132 of 1 frame).
In case of the dispersive drive, the selection signals will be output for four times, separately, within the period of 1 frame.
With this dispersive drive method, it is possible to reduce the frame frequency as compared with the nondispersive drive
method. Therefore, when it becomes necessary to reduce the current consumption, we recommend you to use this dive
method. However, in case of the drive method where moving pictures are to be indicated, the indication may become
flickered and this dispersive drive method is not suitable for indications of moving pictures.

Note: S1D15E06 series maintains the operation status due to the command. However, when exposed to excessive
external noise, internal status may be changed. This makes it necessary to take some measures which reduces
noise generation in terms of installation or system configuration, or which protects the system against adverse
effect of noise. To cope with sudden noise, it is recommended to refresh the operation status on a periodic basis.
