1 System Overview
Introduction
Brightness/Color uniformity is of the most important factors that affect the image quality of a full color LED
display. Because of the limitations of manufacturing process, including system structure design, LED lights
selection, electronic components welting, system cooling, LED brightness decaying and many others, LED
displays suffer the brightness/color uniformity loss, which is also the most serious problem of this field.
Facing this fact, Nova pixel level calibration system does not intervene the manufacturing process of a LED
display to reduce its brightness/color uniformity. Instead, it performs brightness/color adjustment to the display
after it has been completely produced. By adjusting the brightness/color of each LED light according to the
software analytical results from the measured brightness/color values of the LED lights, Nova pixel level
calibration system can help the LED display acquiring perfect uniformity.

NovaCLB is applicable for the following two occasions:
Factory single cabinet pixel level calibration (Factory calibration). Correct each cabinet on the production
line to ensure good brightness/color uniformity of the cabinets when produced.
Field LED display pixel level calibration (Full-screen calibration). Perform calibration for an LED display at
where it locates to improve its brightness/color uniformity.
Factory calibration is more efficient and lower in cost than Full-screen calibration. But for cabinets of which the
LED lights optical axis directions consistency is not well managed, results of factory calibration will not be as
good as that of filed calibration. During factory calibration, the matching NovaCLB-Cabinet is needed.
Full-screen calibration requires engineers to be present and Full-screen installation of calibration instruments.
And what’s more, Full-screen calibration can only be performed only at night when it’s dark. Despite its
complexity and low efficiency (compared with factory calibration), Full-screen calibration can greatly improve
the brightness/color uniformity of a LED display and thus results in amazing image quality of the display.
During Full-screen calibration, the matching NovaCLB-Screen is needed.
This document introduces the detailed operations of full-screen calibration.
