Structure of digital tube

The Led segment display is a figure-eight device, which consists of a plurality of packaged light emitting diodes. The wires have been connected internally, and only their strokes and male electrodes need to be drawn out. The number of segments commonly used in led digital tubes is generally 7 segments, some with decimal points, and some are similar to the 3-bit "+1" type. There are half digits, such as 1, 2, 3, 4, 5, 6, 8, 10, etc. Led digital tube is divided into * * * cathode and * * * anode according to different LED connections. Understanding these characteristics of LED is very important for programming, because different types of digital tubes are different except hardware circuits. Figure 2 shows the internal circuits of cathode and anode digital tubes. They have the same luminous principle, but the polarity of power supply is different. The colors are red, green, blue and yellow. Led digital tubes are widely used in instruments, clocks, stations, home appliances and other occasions. Pay attention to product size, color, power consumption, brightness, wavelength, etc. The following will introduce the pictures of the internal pins of commonly used LED digital tubes.

Figure 1 This is a 7-segment LED digital tube with decimal point 10 pin. Figure 2 Pin Definition.

Each stroke corresponds to a letter, indicating that DP is a decimal point.
