The module is the basic unit of the LED display , and refers to the independent unit of the outdoor LED display. Many business friends are not very familiar with the difference between the LED display module and the river unit board. It is easy to confuse the two. In order to let everyone better understand the basic knowledge of the LED display, the following will introduce you to the first LED network. What is the LED display module and basic LED display module knowledge. 
What is the LED display module?
The LED display module is a self-contained unit that is defined by the circuit and the mounting structure and has a display function to form an LED display. Simply put, for ease of assembly and display, the semi-finished products are usually provided in the form of display modules, and multiple display modules are added together with display drivers. The indoor screen is commonly called "unit board"; the outdoor screen is commonly called "module", and then several modules plus chassis, fan, power supply, etc. are combined into a "box", which is mostly used for large-scale full-color screens.
The composition of the LED display module
The LED display module is one of the main components that make up the finished LED display! Mainly composed of LED lights, PCB circuit boards, driver ICs, resistors, capacitors and plastic kits!
Classification of LED display modules
The LED display module is divided by color. One: monochrome module, such as single red, single green, single blue, single yellow, single white module. Two: Two-color modules such as red and green two-color, red and blue two-color. Three: The full color module mainly uses red, green and blue three primary colors on one LED module.
The picture above shows a 16x8 (2 red) outdoor screen module. With a waterproof structure for all-outdoors, we can see the plastic case, and the far right is its entire structural plan: the display board is inserted with the lamp bead, and the back plate is the display drive circuit, which is the split structure. There are also the overall structure of the display board and the display drive circuit on a circuit board. We can see the difference between the two figures below. The panel and the rear case are actually a plastic cover, and the corresponding lamp bead is provided with a hole in the panel, so that the lamp bead leaks out, and the rear case has a screw hole or a magnetic column for mounting, so that the module is easy to assemble. The front of the module is filled with waterproof glue for the display.
