Installation Characteristics and Requirements
Take the load bearing and spatial distribution of the indoor installation position into consideration in
combination with the environmental characteristics of the operation site, as the Leyard TW Series TV-
wall project is of great importance. The framework installation modes of the TV-wall have the
following characteristics:
•Modular Design: Standard unit frameworks are adopted in installation structure; all
frameworks are standard products. The sheet-metal precision stamping, as well as off-site
processing, is adopted in order to ensure splicing accuracy of framework.
•High Feasibility: The high-rigidity modular frameworks can be quickly installed without
professional personnel, which can reduce the site workload of installation structure.
•High Installation Accuracy: Smoothness per linear meter is ≦0.1mm, clearance of display
unit is ≦0.1mm and error per linear meter is ≦0.1mm. After installing the first line of cabinet,
light up to see if there’s bright black line at the left and right sides of cabinet before installing
the next line of cabinet; then check if there’s bright dark line between the two lines installed
and continue installation until the entire screen is completed.
Installation Methods
Tools: leveling instrument (apparatus), laser range finder, tape measure, M16 wrench, 8mm hexagon
wrench, cross screwdriver and vice
Base Installation & Adjustment
As shown in the schematic diagram for base and framework connection, adjustment sheet is installed
between two frameworks for front/rear leveling; the base structure is provided with threaded holes at
the left and right sides for connection. Leveling shall be made after base is adjusted.
