AR glass is antireflective glass, and AG glass is anti glare glass. As the name implies, AR glass can not only increase the light transmittance, but also reduce the reflectivity. The reflectivity of AG glass is approach 0, which cannot increase the light transmittance. Therefore, in terms of optical parameters, AR glass has more functions to increase light transmittance than AG glass. In terms of optical principle, AR glass is a film that can increase the transmissivity and reduce the reflectivity by adding a layer on the glass surface; AG glass turns reflected light into diffuse reflection. In terms of appearance, AR glass is smooth and transparent, and AG glass is glass with a little frosting effect.

In outdoors, advertising displays are always faced with human and environmental uncertainties, so it is very important to use strong shell materials and anti-strike structural design. Kontech outdoor high brightness LCD displays can withstand vibration, shock and temperature changes in outdoor environments , with high-strength anti-seismic, wind-resistant, and durable features against lightning strikes, it can ensure long-term stable operation.
