Hi, I've been reading about 7 Segment displays and everyone is saying you need to switch between the segments at great speed to make them work correctly.
Is this true?
I can understand that it might be more efficient that way, but what is to stop me from just lighting them at the same time? From what I've read these are all independent LED's that share a common cathode.
So am I right in saying that if I independently resist each LED rather than a generic one at the cathode this should be fine?
Are there and heat issue by lighting them all together?
Do these 7 Segment Display drivers do all the fast switching for you?
Thanks for any info you can give me.
David
