The 7-segment display, also written as seven segment display, consists of seven LEDs (hence its name) arranged in a rectangular fashion as shown. Each of the seven LEDs is called a segment because when illuminated the segment forms part of a numerical digit(both Decimal and Hex) to be displayed. An additional 8th LED is sometimes used within the same package thus allowing the indication of a Decimal Point,(DP).
