1. double-box structure, the formation of internal natural convection mode, so cabinets space temperature reaches equilibrium.
2. pixel module junction box and use the "O" ring, with good moisture anti-leakage performance.
3. The control system only with the IPC, and higher reliability.
4. use of sophisticated large-scale integrated chip high-speed serial transmission network alternative to discrete parallel transmission chip, reducing the complexity of the transmission display, reducing the complexity of the control system to improve the stability of the product.
5. using a common network data transmission technology, improve gradation display variable message signs, information boards enable a better display.
6. Made with high quality Epistar leds keep high quality, low lighting decay, energy saving
7. Brightness can be adjusted automatically according to different surrondings,can be set to open and close the screen on fixed automatically
Variable message signs Application
