1. A dry and constant temperature indoor environment is required. Because if the LCD splicing screen can be operated in a humid indoor environment, once moisture is added to the LCD splicing screen, and the LCD splicing screen must be powered on without removing the moisture. In other words, the humid indoor environment will cause the circuit to oxidize and cause short circuits, etc., and cause the liquid crystal electrodes to be corroded, which will cause permanent damage.
2. Do not install strong light and fluorescent tube in the place where the LCD splicing screen is installed, then install a built-in downlight within 2 meters of the LCD screen, and place all the lights of the display control center on the display screen in parallel The direction is grouped and controlled, and it is not suitable to use a strong light source. For outdoor light that may be incident on the display screen, necessary shielding measures should be adopted.
3. In the installation room, it is best to use non-reflective ground material or anti-static floor (no anti-static floor under the large LCD splicing screen), and install and fix the display base directly on the concrete floor. And check the strength and stability of the wall structure. Because only the wall structure is more stressed than the large screen, the surrounding area of the installation window can be stabilized and not deformed.

4. It should be known that users should provide power supply and LCD splicing large-screen system connection near the construction site, and the air switch should have protection devices such as overcurrent, short circuit and voltage loss. And in order to ensure the display quality, the power supply for the large-screen LCD splicing screen system should be in the same phase, and the air switch and the power cord and socket of the large-screen system should be constructed by the large-screen LCD splicing screen manufacturer.
5. The grounding system should be separately grounded by a dedicated power supply, and a shared grounding body cannot be used for lightning protection grounding, and the dedicated power supply resistance of the dedicated grounding body should not exceed 2 ohms, and other AC working grounds, safety protection grounds and lightning protection The grounding body should be less than 4 ohms. If the integrated grounding system is selected, the grounding resistance should be in accordance with the special power supply resistance regulations (the grounding resistance should not exceed 2 ohms); but if the user's construction site does not have a grounding access point that meets the requirements, It should be clearly marked to facilitate the connection of LCD splicing screen manufacturers with the system after the access point.
6. If a fire fighting system is set up, the fire sprinkler should be about 1 meter away from the large LCD screen, and in the event of an accident, dry powder fire extinguishers should be used to extinguish the fire. Water sprinklers should not be used to prevent water from entering the LCD screen. May cause damage.
