Question

Explain in detail about 7-segment display?

Answer 1

A seven-segment display is a set of seven bar-shaped LED (light-emitting diode) or LCD (liquid crystal display) elements, arranged to form a squared-off figure 8. A few seven-segment displays use other illumination devices, such as incandescent or gas-plasma ("neon") lamps. If all elements are activated, the display shows a numeral 8. When some of the elements are activated but not others, any single-digit numeral from 0 to 9, as well as most uppercase and lowercase letters of the English alphabet, can be portrayed.
Seven-segment displays are commonly used in digital clocks, clock radios, timers, wristwatches, and calculators.
