Relationship between Segment and Digit outputs
Figure 4
Example 1
S1 to S24
Example 2
Example 3
Consider the examples shown in Figure 4, where display data is set up so that the segment outputs S1 to S24 output
V
SS
level on the G1 and G3 digit output timing and V
FL
level on the G2 digit output timing. (Here, the G2 side being
lighted) The relationship between the time t3 and the oscillator frequency f
OSC
is t3 = 2048/f
OSC
.
The digit output G1 to G3 waveforms in Example 1 are output when the dimmer data (DM0 to DM9) are set to
3FEH. The relationship between the time t1 and the oscillator frequency f
OSC
is t1=2/f
OSC
. Note that the time t1 and
the time t2 are the same period in Example 1.
The digit output G1 to G3 waveforms in Example 2 are those when the dimmer data (DM0 to DM9) are set to a
smaller value. Although the time t1 does not change, the time t2 becomes longer.
When the dimmer data (DM0 to DM9) are set to 1FF
H
and the oscillator frequency fosc is 2.4 [MHz], then the time
t2 is :
t2 = t3 – t1
×
(1FF
H
+ 1)
1024
= ——
f
OSC
= 0.43[ms]
When the dimmer data (DM0 to DM9) are set to an even smaller value, the time t2 becomes even longer, as in
example 3. Note that the time t1 does not change here, either.
