I have a simple question, but cannot find the answer anywhere and the datasheets are not very clear. Each 7-segment display have maximum current per segment. If this current is 40mA, single digit display can draw 40mA * 7segments = 280mA. OK...
Here is the question - if a datasheet of a 4 digit display states maximum current per segment 40mA, does a 4 digit display draw 280mA * 4digits = 1.112A (a lot!) ? Or does the value mean "maximum current per segment of all digits shining simultaneously" ?
