Abstract

The invention discloses a universal 8-segment LED digital display device, comprising a body circuit board, a light-emitting diode display, function conversion sockets and a function conversion plate. The body circuit board is provided with a character-shaped 8-segment LED digital display composed of segment mark lines, each segment mark line is internally equipped with a plurality of high brightness LEDs, and a decimal point segment mark line is internally equipped with one high brightness LED; the body circuit board is provided with a plurality of function conversion sockets; both cathodes and anodes of the LEDs at each segment are all interconnected together, the cathodes and the anodes of the LEDs are respectively correspondingly connected to the function conversion sockets one by one;the function conversion plate is provided with a plurality of pins and with a direction mark groove at one side thereof; the universal 8-segment LED digital display device has the obvious advantage that mutual structural conversion between common cathode 8-segment LED digital display device and common anode 8-segment LED digital display device is realized by the unction conversion plate, and alsohas the characteristics of scientific and reasonable design, low cost, convenient combination, flexible usage, etc.

Description

technical field [0001] The invention relates to a general-purpose 8-segment LED digital display device, which belongs to the technical field of electronics. Background technique [0002] 8-segment LED digital display is a common component in the field of computers and instruments, especially large-scale digital displays, which have been widely used in education and teaching, banking and stock markets, stations, docks, information advertisements and other fields. However, the 8-segment LED digital displays in the prior art are divided into two types: a common cathode type and a common anode type. According to actual requirements of different designs and research and development, both types of 8-segment LED digital displays will be used respectively. [0003] The single-chip microcomputer experimental teaching devices produced by different manufacturers or the intelligent instruments developed by themselves have both types of common cathode and common anode for the 8-segment L...
