2. Seven-segment display - Wikipedia

   en.wikipedia.org/wiki/Seven-segment_display

   A typical 7-segment LED display component, with decimal point in a wide DIP-10 package. A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays.

3. Seven-segment display character representations - Wikipedia

   en.wikipedia.org/wiki/Seven-segment_display...

   The following phrases come from a portable media player's seven-segment display. They give a good illustration of an application where a seven-segment display may be sufficient for displaying letters, since the relevant messages are neither critical nor in any significant risk of being misunderstood, much due to the limited number and rigid domain specificity of the messages.

4. Charlieplexing - Wikipedia

   en.wikipedia.org/wiki/Charlieplexing

   In the following Arduino code example, the circuit [38] [39] uses ATtiny 8-pin microcontroller which has 5 I/O pins to create a 7-segment display. Since a 7-segment display only requires control of 7 individual LEDs, we use 4 of the ATtiny I/O pins as Charlieplexed outputs (n (n - 1)), i.e. the 4 pins could be used to control up to 12 ...

5. Nixie tube - Wikipedia

   en.wikipedia.org/wiki/Nixie_tube

   Nixie tubes were superseded in the 1970s by light-emitting diodes (LEDs) and vacuum fluorescent displays (VFDs), often in the form of seven-segment displays. The VFD uses a hot filament to emit electrons, a control grid and phosphor-coated anodes (similar to a cathode-ray tube ) shaped to represent segments of a digit, pixels of a graphical ...

6. Dual in-line package - Wikipedia

   en.wikipedia.org/wiki/Dual_in-line_package

   For example, for a 14-lead DIP, with the notch at the top, the left leads are numbered from 1 to 7 (top to bottom) and the right row of leads are numbered 8 to 14 (bottom to top). Leads are skipped on some DIP devices (e.g. segmented LED displays, relays, or devices that replace leads with a heat sink fin). The remaining leads are numbered as ...

7. Nine-segment display - Wikipedia

   en.wikipedia.org/wiki/Nine-segment_display

   More variations. A nine-segment display is a type of display based on nine segments that can be turned on or off according to the graphic pattern to be produced. It is an extension of the more common seven-segment display, having an additional two diagonal or vertical segments (one between the top and the middle, and the other between the bottom and the horizontal segments).

8. Digital clock - Wikipedia

   en.wikipedia.org/wiki/Digital_clock

   A digital clock's display changing numbers. To represent time, most digital clocks use a seven-segment LED, VFD, or LCD for each of the four digits. They generally also include other elements to indicate whether the time is AM or PM, whether or not an alarm is set, and so on. Older digital clocks used numbers painted on wheels, or a split-flap ...

9. Dot-matrix display - Wikipedia

   en.wikipedia.org/wiki/Dot-matrix_display

   A 16×2-character dot-matrix display, where each character is made from a grid of 5×7 dots. A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.
