Common Output State Selection Circuit (see Table 7)

Since the common output scanning directions can be set using the common output state selection command in the

ML9058E, it is possible to reduce the IC placement restrictions at the time of assembling LCD modules.

LCD Drive Circuit

This LSI incorporates 181 sets of multiplexers for the ML9058E, that generate 4-level outputs for driving the LCD.

These output the LCD drive voltage in accordance with the combination of the display data, common scanning

signals, and the FR signal. Fig. 6 shows examples of the segment and common output waveforms in the frame

reversal drive method.

Static Indicator Circuit

The FR pin is connected to one side of the LCD drive electrode of the static indicator and the FRS pin is connected

to the other side.

The static indicator display is controlled by a command only independently of other display control commands.

The electrode of the static indicator should has a wiring pattern that is distant from the dynamic drive electrode.

If the wiring pattern is placed too near to the dynamic drive electrode, the LCD and electrode may be degraded.
