4, by pixel density or pixel diameter division. As the indoor screen using LED dot matrix module specifications are more unified so usually in accordance with the module pixel diameter is divided: ∮ 3.0mm 62500 pixels / square meter ∮ 3.75mm 44321 pixels / square meter ∮ 5.0mm 17222 pixels / square meter.
5, according to the display performance can be divided into. Video display: generally full-color display; text display: generally single-color display; graphic display: the general dual-color display; Quotes display: generally digital or single color display.

LED digital display: display device for the 7-segment digital tube, suitable for making the clock screen, interest rate screen, LED Panel display digital electronic display; LED dot matrix graphic display: display device LED video display: display device is composed of many light-emitting diodes, can display video, animation and other video files; conventional type of light-emitting diodes, a variety of light-emitting diodes, LED display: the use of steel structure will be fixed in a fixed position. Mainly in the outdoor large-scale single-column LED advertising screen, and the station installed on the wall used to play trips information single, two-color LED display, etc .; rental LED display: in the design, R & D department to take into account the screen Often used for installation and removal, so the right and left box with a positioning function of the quick lock connection, positioning accuracy, the entire box installed within 10 seconds to complete.
