Outdoor P4 Led Display_Standard_Shenzhen Hongshi Holding Co., Ltd

Describe

Parameter

This product uses self-packaged SMD 1921 lamp beads, and one red chip, one green chip and one blue chip are packaged in the lamp bead. The 1921 lamp beads are soldered on the PCB board by surface mount technology (SMT).

This product uses a dynamic energy-saving driver IC chip and an integrated row driver chip controlled by a computer; the display angle is wide, the color is pure and consistent, the brightness is stable and uniform, and the text, image and video are clear.

The lamp beads and chips are mounted on the PCB board to form a unit board, and then installed on the bottom case to form a module. It has the characteristics of preventing direct sunlight, dustproof, waterproof, high temperature resistance, etc. Its appearance is exquisite and beautiful, and it is durable.

The bottom case has M4 threaded holes for mounting modules. The magnetic column can be installed on the module, and then assembled into a whole screen, or the module can be adsorbed and fixed on the cabinet with a specific magnetic column, and then the cabinet can be spliced into a whole screen.
