    Low Reflection Design

    The surface of Chainzone’s VMS is of a unique matte abrasive structure which creates a diffused reflection of the sunlight; thus reducing the brightness reflection from the front surface of the VMS.

    The optical lens of Chainzone’s VMS is designed to achieve light absorption which will decrease the external light reflection on the lens, so the brightness reflection of the VMS is furtherly reduced.

    With the matte abrasive surface and the external light absorption design on lens, the luminance ratio of Chainzone’s VMS can reach as high as 20:1 in white color, under the external illumination at 40000 lux


    Smooth Surface Design

    Unlike some traditional VMS structures designed to have visors for the LED pixels on the surface to increase the luminance ratio, Chainzone’s VMS surface with optical lens is smoother, so no dust or snow will stay on the VMS surface. The display content on the VMS will remain clear and complete all the time.
