LED Digital Display

LED digital display is a semi-conductive lighting component, with light emitting diode (LED) as its elementary unit. By the number of segments the digital display is made of, there are 7-segment digital displays and 8-segment ones, with the latter with one more LED unit (also displays one more decimal point) than the former. By the number of the figure “8” displayed, there are 1-digit, 2-digit, 4-digit LED digital displays and so on. And by the way in which the LED units are connected, there are common anode digital displays and common cathode digital displays.


There are mainly two kinds of LED components: digital displays and dot matrix. As a kind of LED components, 8-segment digital display is also called 8-digit display. It is divided into 8 segments: A, B, C, D, E, F, G, and P, with P representing the decimal point. The digital displays usually use 10 pins, 1 pin for each segment and the other 2 interconnected pins at the common end of the digital display. The digital display can display time, date, temperature and other information that can be represented by digitals.


With all the advantages including rich color range, high brightness, low energy consumption, rapid response and convenient match with IC decoder and IC driver, LED digital displays are widely used in digital display applications in different kinds of meters, instruments, and especially in the household appliances like air conditioners, refrigerators, microwave ovens, induction cookers and most water heaters, etc.
