System Description
The HD66420 can display a maximum of 160
×
80 dots (ten 16x16-dot characters
×
5 lines) four-level gray
scale or four colour LCD panel. Four levels of gray scale can be selected from 32-levels, so the appropriate
4-level gray scale can be displayed.
The HD66420 can reduce power dissipation without affecting display because data is retained in the
display RAM even during standby modes. An LCD system can be configured simply by attaching external
power supply, capacitors and resistors (figure 1) since the HD66420 incorporates power circuits.
