In the former case, the device is known as a common-anode seven-segment display in the latter case, the device is known as a common-cathode seven-segment display.įIGURE 3. If the display is an LED type, the seven individual LEDs may be arranged in the form shown in Figure 3, in which all LED anodes are connected to the common terminal, or they may be arranged as in Figure 4, in which all LED cathodes are connected to the common terminal. Practical seven-segment display devices must be provided with at least eight external connection terminals seven of these give access to the individual photoelectric segments, and the eighth provides a common connection to all segments. The segments are conventionally notated from a to g in the manner shown in the diagram, and it is possible to make them display any number (numeral) from 0 to 9 or alphabetic character from A to F (in a mixture of upper and lower case letters) by activating these segments in various combinations, as shown in the truth table in Figure 2.įIGURE 2. Standard form and notations of a seven-segment display. The best known type of alphanumeric indicator is the seven-segment display, which comprises seven independently-accessible photoelectric segments (such as LEDs or LCDs, or gas-discharge or fluorescent elements, etc.) arranged in the form shown in Figure 1.įIGURE 1.

Digital watches, pocket calculators, and digital multimeters and frequency meters are all examples of devices that use such displays. » Skip to the Extras SEVEN-SEGMENT DISPLAYSĪ very common requirement in modern electronics is that of displaying alphanumeric characters.
