P31.25 full color traffic LED display screen


Traffic guidance display is mainly used in traffic information signs, roadside advertisement, so it has a special requirement of the stability, eye-catching and synchronous multi-screen control.
1. It has an ultra-stable performance, for it has passed a 30 days strict ageing and multi-channel testing and can support a continuous working of 10000 hours.
2. It has a pure and standard color. The ERALEDs have a strict regular for the color range to assure the purity of the color.
3. It has a small angle but high brightness. The small-angle "V" shaped cup can ensure the absolute brightness of light and the capability of penetrating the fog and haze.
4. It can support a remote and wireless control. Considering that the dispersion character of the display and the timeliness of information, we provide a new route guidance screen control method - ultra-long-range wireless control, allowing customers to achieve a nationwide wireless remote control for a single or a series of screen without leaving home.
