Interfacing with the Liquid Crystal Panel
By connecting the HD66730 to extension drivers, the display can be expanded up to a 1-line/40-character,
2-line/20-character, or a 4-line/10-character display configuration. Bits DT1/0 set the duty drive ratio and
bits NC1/0 set the number of characters per line. In addition, bits NL1/0 sets the number of display lines
during display read control. Table 22 shows the relationship between the number of characters actually
displayed on the liquid crystal panel and the corresponding number of extension drivers needed.

Notes: 1. Numbers in parentheses = (number of extension segment drivers/number of common drivers)
2. This is an example when using the 40 output extension drivers, and when Nh represents display
characters and Nd extension driver outputs, the number of extension drivers needed can
generally be calculated as follows:
[Number of extension drivers] = (12 * Nh – 71 – 1)/Nd]
↑
3. The right-edge segment (space between characters) is not displayed in 6-character or 16-
character display.
4. Horizontal smooth scroll cannot be performed during an 1-line/40-character, 2-line/20-character,
3-line/10-character, or 4-line/10-character display.
