Dot matrix screen refers to how many pixels can be displayed on the display screen in length and width, or how many LEDs can be lit at the same time in length and width on the LED display screen.
Taking full color as an example, dot matrix screen technology is to encapsulate 192 LED chips in three colors in a module, and the modules form a unit board, and the unit board forms a display screen.
Dot matrix is a geometric term in itself, and the English name is: lattice. It is a lattice frame, similar to the meaning of a lattice frame. It is originally a spatial noun. If it is taken out of the plane, it is not related to the arrangement of the lamp beads of the display screen. Designing the display dot matrix refers to how many pixels can be displayed on the display screen in length and width, or how many LEDs can be lit at the same time in length and width on the LED display screen. It is deeply related to the mesh structure of our digital analog circuit.
