ROE's LED signs are refined to single illumination mold train. The selection of each illumination mold train is designed nimbly according to the actual use environment of customer marking, including illumination mold train in LED quantity, color, density, and angle. The brightness and color of mold train is adjusted by corresponding control system and that  causes the final effect of marking to be consistent with the marking standard color.

Sign engineering is systemic coming down to very complexed lays from structure to circuit, material selection to design, work to quality control, fixing to line pacing. Each step requires rigorous work. ROE take charge a complete set of scheme to realize it.ROE will create your own Made-to-Measure signs with rigorous structural design , specialized control design and fine work.
