Functional Description
1. Display Size Programming
A variety of display sizes can be programmed by changing the system configuration and internal register
settings.
(1) System Configuration Using One HD66108T Chip
When the 65-row-output mode is selected by internal register settings, a maximum of 100 dots in the
X direction can be displayed (Figure 3 (a)). Display size in the Y direction can be selected from 32,
34, 36, 48, 50, 64, and 65 dots according to display duty setting. Note that Y direction settings does
not affect those in the X direction (100 dots).
When the 33-row-output mode is selected by internal register settings, a maximum of 132 dots in the X
direction can be displayed (Figure 3 (b)).
Table 1 shows the relationship between display sizes and the control register’s (FCR) ROS and DUTY
bits. ROS and DUTY bit settings determine the function of X pins. For more details, refer to “4.1 Row
Output Pin Selection.”
(2) System Configuration Using One HD66108T Chip and One HD61203 Chip as Row Driver
A maximum of 64 dots in the Y direction and 165 dots in the X direction can be displayed. 48 or 64
dots in the Y direction can be selected by HD61203 pin settings (Figure 3 (c)).
(3) System Configuration Using Two or more HD66108T Chips
X direction size can be expanded by 165 dots per chip. Figure 3 (d) shows a 265
×
65-dot display. Y
direction size can be expanded up to 130 dots with 2 chips; a 100
×
130-dot display provided by 2
chips is shown in Figure 3 (e).
