Consider a common 7-segment display, like this one. I noticed in the datasheet schematic, they show one LED per segment, which may just be schematic, although for a larger display they show 3 LEDs per segment, so maybe they are showing the actual number of LEDs per segment. In any case, here is my question:
How is a display segment in a 7-segment display constructed such that one LED can uniformly illuminate the entire segment?
I have tried to make my own LED segment by putting an LED behind some partially translucent white acrylic. I always get a fairly localized bright spot and not the uniform illumination that you get in a 7-segment display. Maybe I just need to line up more LEDs for each segment? Or is there a trick?
thanks,
Kevin
