Hi! I am trying to design a circuit with the use of a 7 segment display, I am just a little confused about it's forward current. Should the current consideration be in between each segment or the current as a whole?
Here is the datasheet of the 7 segment that I am using, in this, it shows the current requirements of the 7segment but I am not quite sure if they are for individual internal diode? or not? or are they?
For example is at the Absolute Maximum Ratings, the DC forward current and the Peak forward current, does these values represent the requirement as whole? And even the different graphs, do they represent the whole 7segment or just the invidual internal diode requirement?
