1. A PCB arrangement and wiring structure of LED lamp beads, comprising:
a carrier board, wherein at least one set of LED lamp bead installation areas is arranged on the carrier board, at least one set of the LED lamp bead installation area is in a matrix form, the installation area comprises a plurality of sets of pins, and each set of the pins comprises a VDD pin, a DIN pin, and a VSS pin;
all the VDD pins are connected and wired in parallel with each other, and all the VSS pins are connected and wired in parallel with each other, so that the voltage between each set of lamp beads remains consistent;
all the DIN pins are connected and wired in parallel with each other, so that the working state of each lamp bead can be separately controlled;
the carrier board is further provided with at least one set of VDD power input pin terminals, VSS power input pin terminals, and DIN control terminals, where one VDD power input pin terminal, one VSS power input pin terminal, and one DIN control terminal constitute one set, a plurality of the VDD pins are electrically connected to the VDD power input pin terminal, a plurality of the VSS pins are electrically connected to the VDD power input pin terminal, and a plurality of the DIN pins are electrically connected to the DIN control terminal; and
the VDD power input pin terminal, the VSS power input pin terminal, and the DIN control terminal are arranged on a side or a back face of the LED lamp bead installation area.
