Display Blanking
Blank the display by loading a blank or space into each digit of the
display or by using the (BL) display blank input. Setting the (BL)
input low does not affect the contents of data memory.
A flashing circuit can easily be constructed using a 555 as table
multivibrator. Figure 3 illustrates a circuit in which varying R1
(100K~10K) will have a flash rate of 1.0 Hz~10 Hz.
The display can be dimmed by pulse width modulating the (BL) at
a frequency sufficiently fast to not interfere with the internal clock.
The dimming signal frequency should be 2.5 kHz or higher. Dim-
ming the display also reduces power consumption.
An example of a simple dimming circuit using a 556 is illustrated in
Figure 4. Adjusting potentiometer R3 will dim the display by chang-
ing the blanking pulse duty cycle.
