What is the digital tube of LED display?

　　In fact, the LED digital tube (digital tube) of the LED display is a semiconductor light-emitting device, and its basic unit is a light-emitting diode. The digital tube is divided into seven digital tubes and eight digital tubes according to the number of segments, and the eight-segment digital tube has one more light-emitting diode unit (one more decimal point display) than the seven-segment digital tube. According to how many "8" can be divided into 1 bit, 2 bit, 4 bit and so on digital tube; It is divided into common anode digital tube and common cathode digital tube according to the connection mode of light-emitting diode unit.

　　LED light-emitting devices are generally used in two categories: digital tubes and lattice. The 8-segment digital tube belongs to a kind of LED light-emitting device. The 8-segment digital tube, also known as the 8-font digital tube, is divided into 8 segments: A, B, C, D, E, F, G, and P. Where P is the decimal point. Digital tubes commonly have 10 pins, each segment has a pin, and the other two pins are the common end COM of a digital tube, and the two are connected to each other. You can display: time, date, temperature, etc. with parameters that can be replaced by digits.

　　Because the LED digital tube has the advantages of: rich color, high brightness, low power consumption, fast response speed, easy to use directly with the integrated circuit decoder and driver, the digital tube is mainly used for all kinds of meters, instruments, household appliances and other digital display. In particular, the field of home appliances is widely used, such as: air conditioners, water heaters, refrigerators, microwave ovens, induction stoves, the vast majority of water heaters, etc., are digital tube applications.
