6-2. Waveform Generation Function

This device is equipped with a function to generate four kinds of the normal drive waveform, and one kind of the

refresh waveform.

Each waveform can set the output level and the output time.

6-2-1. Normal Drive Waveform

The normal drive waveform is divided into 12 sections and can set the output level and the output time of each section

by the registers.

The output level of one section selects among 3 levels of +15V, 0V, -15V.

The output time of one section selects from the range of 1ms to 256ms.

Transition of the following image state can set the normal drive waveform each.

White image

⇒ White image

White image

⇒ Black image

Black image

⇒ White image

Black image

⇒ Black image

Output driver outputs one waveform by setting START Flag.

White and black can turn over by setting DB Flag.

6-2-2. Refresh Drive Waveform

The image is changed to full screen white or full screen black by the refresh drive waveform.

The refresh drive waveform is divided into 4 sections and can set the output level and the output time of each section

by the registers.

The output level of one section selects among 3 levels of +15V, 0V, -15V.

The output time of one section selects from the range of 8ms to 2048ms.

Output driver outputs one waveform by setting START Flag.
