Embodiment 1

[0036] Embodiment 1: A wiring circuit suitable for wiring in the LED light-emitting area of ​​a dot-matrix circuit board, and the pads replace the base material to reflect light. Multiple wirings and multiple pads in the LED light-emitting area of ​​the dot-matrix circuit board are combined into an overall pattern, and the light-emitting The area forms a circular or elliptical wiring circuit combination, covering the white base material of the LED light-emitting area of ​​the dot matrix circuit board, forming a wiring circuit that uses the wiring in the light-emitting area and the pad instead of the base material as a reflector. After this treatment, the problem of the color difference of the white CEM-3 base material is solved; in addition, the base material can be easily made of insulating materials of any color and material composition, such as yellow, black, and natural colors, which can reduce the cost of dot matrix lines. Board cost can be up to 20% more. At the same tim...
