HD66765 Datasheet, PDF (60/71 Pages) Hitachi Semiconductor – 396-channel Segment Driver with Internal RAM for 4096-color Displays

HD66765
Common Driver Interface
The HD66765 and the HD66764 common driver can drive displays of up to 132 (RGB) × 176 dots in
size. Signals to set instructions for CR oscillation, the display timing signal, and the common driver are
supplied from the HD66765 to the common driver. The LCD drive voltage is generated by the common
driver. The LCD segment drive level (VSH) is also supplied from the common driver. On/off control of
the display is required to be controlled by both the common and segment driver. Follow the on/off
sequence of the display.
