How does a multi digit cell segment display work in the bases to report this lecture, will we with
this question?
A seven segment display consists of seven ladies that can be illuminated to show a specific decimal
number as the ladies in the seven segment display available on the basis three board are in the common
a. configuration to turn on a segment, we should drive that segment with the logic value zero.
Therefore, to show number three, we should drive a segment with one zero one one zero zero zero zero
binary code.
There are 47 segment displays available on the basis three more, they have two groups of signals,
data signals and control signals.
Its seven segment has its own control line.
If a control line is zero, the corresponding southern segment is on.
Otherwise, it is of.
There are eight data lines corresponding to seven segments plus decimal point on each display, these
data are shared among Display's.
Therefore, only one display should receive the data at a time.
These are the seven segment codes for BCT digits from 029 that we use along this course.
As we know, some the segment displays share the data lines, how can we drive for displays to show
a multi digit number?
The next lecture will cope with this question.
These are our takeaway messages, multiple segment displays usually have the same data lines, but they
have their own control lines.
Certain segments in this report are configured as common items, therefore, to turn on a segment,
the corresponding data line should be zero.
To activate seven segment display on bases to report the corresponding control signal should be zero.
Now, the quiz question, how many patrons can be shown on a seven segment display?
