![]() Seven-segment displays are widely used in digital clocks, electronic meters, and other electronic devices for displaying numerical information.A seven segment display, as its name indicates, is composed of seven elements. A SSD has 7 segments and theoretically we can use it to display 2^7 = 128 combinations of characters. They can be used as an alternative to complex display's such as dot matrix. Verilog code for BCD to 7-segment display converter A seven-segment display (SSD) is a form of electronic display device for displaying decimal numbers. This article discusses how to design a BCD to seven segment display decoder circuit using logic gates.īCD to Seven Segment Display Decoder Theory Generally, it has four input lines as well as seven output lines. For that, a display decoder can be employed for converting BCD code to seven segment code. However the outputs of these are in the type of 4-bit BCD (Binary Coded Decimal), so not appropriate for directly operating the seven segment display. These displays are frequently driven by the output phases of digital integrated circuits like decade counters as well as latches. But, a seven segment display is used to display both the numbers and characters. Usually, the displays like LED’s as well as LCD’s are used to display the characters as well as numerical numbers. The Seven segment display is most frequently used the digital display in calculators, digital counters, digital clocks, measuring instruments, etc. ![]()
