6. DISPLAY EXAMPLES
Figure 6–1 shows how the data memory contents and LCD display pattern are corresponded, when displaying
characters "AEZ" in 8-time-division mode.
This example is to display 3 digits of 5
×
7 (5
×
8) dot characters, and uses data memory addresses 00H to 0EH
(0 to 14) and column signals C0 to C14.
Figure 6–2 shows the timing waveforms for displaying character "A" in columns C14 to C10 for the display example,
shown in figure 6–1.
Figure 6–3 shows how the data memory contents and display pattern are corresponded, when displaying characters
" " in 16-time-division mode.
This example is to display 5
×
7 (5
×
8) dot characters in two rows, 3 digits in each row, and uses data memory
addresses 00H to 0EH (0 to 14) in data memory banks 0 and 1 and column signals C0 to C14.
Figure 6–4 shows the timing waveforms for displaying character " " in columns C14 to C10 for display example,
shown in Figure 6–3.
In Figure 6–2 and Figure 6–4, when the differential waveform levels between the row signal and column signal are
V
LCD
and –V
LCD
, the LCD dot corresponding to these signals will be lit.
