Product Details
Single digit, 1.2. inch digit, 7-segment diplay, common anode or
common cathode.
Single digits 7 segment led display
Seven-segment displays use light-emitting diodes to release light
energy in the form of photons. The product is illuminated to show
the numbers in all seven sections, with the eighth section being
the decimal point.
When this happens, remember that an LED is a solid-state optical
p-n junction diode. So it allows current to flow through its
junction.
The diode facilitates the forward flow of current from an external
voltage, a process known as electroluminescence. The color ranges
from red to blue to green, depending on various impurities in the
semiconductor material that helps produce it.
The decimal point comes in handy when connecting two or more
seven-segment displays. The reason is to display decimal numbers or
to give multi-digit representations.
