6.6 Liquid Crystal Drive Circuit

6.6.1 Segment Driver

This SEG output circuit selects from five values of V

, V

, MV

and MV

using the driver control signal

determined by the decoder and outputs them.

6.6.2 Common Driver

This COM output circuit selects from three values of V

, V

and V

SSH

using the driver control signal

determined by the decoder and outputs them.

This IC can set the COM output scanning direction and select normal drive or interlace drive using the select

common output status command (See Table 6.7.). Therefore, IC arrangement comes to be less restricted when
the LCD module is assembled.
