Consultants, architects, integrators, and end users must establish their priorities when buying a led wall tiles. What are the critical factors that will enter making that decision: price, components, and length of warranty; percentage of free spare parts; reputation of supplier for references?

“Common Cathode”, refers to the common cathode power supply, in fact, is a led display energy-saving technology, refers to the use of common cathode way to power the led display, that is, the use of led beads R, G, B (red, green, blue) to separate the power supply, accurate respectively for R, G, B beads to allocate current voltage, due to R, G, B (red, green, blue). G, B (red, green, blue) lamp beads required by the best working voltage and current is not the same, so that the current will first go through the lamp beads and then to the IC cathode, the forward voltage drop will be reduced, the on-state internal resistance will become smaller.

Refresh rate is the number of times the electron beam is repeatedly scanned to the image on the screen. The higher the refresh rate, the better the stability of the displayed image (screen). The display monitor refresh rate will directly determine the price, but because the refresh rate and resolution of both constraints, so only in high resolution to achieve a high refresh rate so that the monitor can be called its excellent performance.
