Appendix E. Display Brightness
Two ways have been shown to control the brightness
of this LED display: setting the peak current and setting
the duty factor. Both values are set in Control Word 0.
To compute the resulting display brightness when both
PWM and peak current control are used, simply multi-
ply the two relative brightness factors. For example, if
Control Register 0 holds the word 1001101, the peak
current is 73% of full scale (BIT D
the PWM is set to 60% duty factor (BIT D
= H, BIT D
44% (.73 x .60 = .44) of full scale.
The temperature of the display will also affect the LED
brightness as shown in Figure 5.
