LED dot matrix display combination type.P3 indoor LED module

　　The combined LED dot matrix display takes the light-emitting Diode as the graphic element. It is composed of high brightness LED chips and then packaged with epoxy resin and plastic mold. It has the characteristics of high brightness, low power consumption, few pins, large viewing angle, long service life, moisture resistance, cold and hot resistance, and corrosion resistance.

　　There are two types of dot matrix displays: single color and dual color, which can display red, yellow, green, orange, etc. LED dot matrix has 4 × 4. 4 × 8. 5 × 7. 5 × 8. 8 × 8. 16 × 16. 24 × 24, 40 × More than 40 types; According to the number of pixels, it can be divided into equal, dual primary colors, triple primary colors, etc.

　　The internal circuit structure and external specifications of several LED dot matrix displays, and the structures and pins of other types of dot matrix displays can be obtained through tests. When using a single LED dot matrix display, it can not only replace the Nixie tube to display numbers, but also display various Chinese and Western characters and symbols. For example, the 5 x 7 dot matrix display is used to display Western letters. 5 × The 8 dot matrix display is used to display Chinese and Western languages, the 8 x 8 dot matrix is used to display Chinese text, and can also be used for graphic display. A combination of multiple dot matrix displays can form a large screen display, but such practical devices are often controlled and driven by microcomputers or microcontrollers.
