4. DISPLAY DRIVING CIRCUIT

The display driving circuit of µPD161830 consists of γ-resistance and γ-selection switch (SW) which are shown

below, a D/A converter, and an output stage.

The function of each block is as follows.

γ-resistance

: It is string resistance for γ-curve.

γ-selection switch (SW): Change γ-curve at the time of a positive and a negative drive.

D/A converter

: Choose an output voltage level from display data.

Output stage

: It consists of amplifier for a drive and a switch for a voltage maintenance drive, and an

inverter for 8 color displays.
