The difference between LED dot matrix display and LED display

The original dot matrix LED screen is a kind of LED display, a branch, LED display is divided into:

In-line LED display, generally for outdoor and semi-outdoor screens; one for surface mount type, referred to as surface mount, with three-in-one and three-in-one stickers, generally for indoor display; followed by dot matrix The display screen is similar to the 5050 and the surface mount three-in-one. One lamp is packaged with one, two, and three chips, respectively, which correspond to monochrome, two-color, and full-color. The dot matrix screen is generally composed of small modules of 8 dots × 8 dots, so it is called a module.

There is also a relatively low brightness of the LED dot matrix display. The LEDs (that is, the lamps) in the LED dot matrix screen are packaged into modules. Because of this, its specific module limits the driving mode of the LED dot matrix screen, which directly affects its brightness. High, and each LED in the LED screen is controlled separately. There are multiple choices in the driving mode and circuit design, and the brightness can be designed to be much higher.

The dot matrix screen is mainly limited to the "dot matrix" display, which is a relatively simple and relatively low cost equipment. The broken part does not affect the other part, and the maintenance is simple. It is enough to replace the bad one.

The common use of LED dot matrix displays acts as an information screen for displaying text and simple pictures. The general dot matrix display is used indoors, mostly in the low-end single and double colors, used to scroll display text and pictures (two-color playable video), but also full color. The price of the dot matrix display is relatively low, the heat dissipation is not very good, and the effect is general, so the color screen is rarely used.
