Frequently Asked Question

Do you have any question?

Chainzone displays smoothly control the transition from daytime brightness to nighttime brightness through use of a light sensor. The light sensor measures ambient light conditions throughout the day, and smoothly transitions the brightness of the display as the sun sets or rises, or if there are overcast conditions. The sign administrator also has complete control of the daytime and nighttime brightness values which gives them the opportunity to customize each sign to the requirements of each locale.

Technically, a NIT measures 'luminance'. It is the absolute measurement of light from a light source. The technical definition of a NIT is as follows: NIT: The candela per square metre (cd/m2) is the derived International System unit (SI) of luminance. 1 nit = 1 cd/m2.

Optimal viewing range is based on legibility of the smallest "standard" (seven pixel height) alpha‐numeric character for any given display pixel pitch. LED message centers are very dynamic and the viewing distances in the chart below are for general reference. Using different font types and styles can affect the legibility of the display greatly. With enough distance, virtually any pitch of display will blend into a continuous image – where pixilation (seeing individual diodes or pixels) is no longer present in the display. If a user is only displaying text, pixilation may not be a large concern. However, this usually becomes a much bigger issue if the user is intending to run images or video on the display.
