LED display installation technology

First, the LED display in vitro structure flatness detection if conditions allow, also can use the theodolite can hang line, hanging vertical and other methods, the strict testing horizontal, vertical component meets the drawings accuracy.

Second, the testing tolerance standards
* the led panel in vitro border, medial error < + 1 mm diagonal
* vertical structure positive centerline vertical degree < + 0.5 mm
* longitudinal component and the center of the component from error < + 0.5, and the accumulative error < + 1 mm
* longitudinal component itself "+ 0.5 mm error of flatness
* horizontal component (8 # channels for roughness regulator) and spacing is not more than four component unit module spacing error < + 5 mm
* finally is the overall structure of the flatness detection error < + 1 comprehensive mm.

Three, the LED display module installation
* the first line and the middle column installed in place, set the horizontal, vertical auxiliary hang line. Adjust the parallel degree and vertical degree, the error < + 0.5
* sure level and vertical hang up the middle column can be removed, and then by the upward, from left to right to start the installation the led panel module.

Four, unit display module installation error
* module and modules flatness < + 0.5 mm
* module spacing between pixel error < + 0.3 mm
* modules installed after the body surface smoothness, screen "+ 1 mm.
