  2. The fixed LED modules are then placed one by one after that.
  3. Next, connect the necessary wires for power, controls, and other components. The final step is to light up the LED screens to demonstrate its programmed display. It is optional to control the LED’s arrangement. 
Module Testing and Aging

The indoor LED module underdoes testing for aging. This test comprises an extensive operational assessment of the actual performance to check for any problems. Additionally, aging can enhance its effectiveness and reliability. That includes the reason for LED aging as part of the module quality test. 

The following evaluation must complete before an aging test for LED modules may be conducted.

    • First, by ensuring that the modules are connected properly
    • Second, inspecting for short circuits.
    • Third, determining if the modules are compact and uniform.
    • Fourth, review of appearance and the entire structure.
    • Last is where the performed aging test takes place
