At present, LCD splicing has replaced the dominant position of DLP large screens. It is widely used and covers almost the entire market, but some customers still choose DLP large screen products with small stitching. In a market flooded with LCD splicing, you may hear some related information about LCD splicing. However, the innovation of DLP large screen has not stopped, and the laser DLP large screen product has been successfully launched, although it is not very good. Mature, however, it solves the shortcomings of traditional rear projection. Whether the future is the world of LCD splicing or DLP large screens is still unknown. Therefore, here to share with you some DLP large screen installation and maintenance knowledge of DLP large screen.
Precautions during installation and use
When the machine is moving, it should be handled gently, pay attention to shock, rigorous impact, squeeze and vibration. During the installation process, only one screen can be moved at a time to avoid scratching other screens. When cleaning the screen surface, pay attention to use a soft cloth to wipe it. Do not wipe the screen with hard things or use chemical cleaning agents to clean it. When your screen is not used for a long time, you should cut off the power.
The site where the equipment is located should be kept clean and free of debris, and the ground should be kept dry. The best temperature in the equipment room is between 17 ℃ and 27 ℃. The load-bearing capacity of the ground at the installation location of the splicing wall is not less than 300kg ∕ ㎡. In addition, the wires and cables of all power distribution lines in the equipment room should be protected by metal trunking or conduit, and the grounding system should be properly prepared. All wires and cables should be flame retardant or flame retardant cables.
Maintenance of optical equipment
The screen is placed in a ventilated place to prevent dust and heat. The DLP box has a heat dissipation system, but the high-speed airflow is still absorbed by the dust in the heat dissipation system after passing through the filter mesh, and the dust is collected inside the large-screen optical equipment, which will affect the picture quality. In use, pay attention to the dust and smoke of the screen, and regularly clean the dust filter.
Regular large-scale cleaning of large-screen optical equipment can improve the brightness and contrast of large-screen display systems (increased by 10% to 30%). In use, pay attention to the maintenance of daily optical components (color wheel, liquid crystal panel, polarizing plate, lens, etc.) to prevent premature aging.
If it is a traditional rear projection, it is necessary to use UHP light source, the lamp life almost determines the quality and life cycle of the screen. During use, it is strictly forbidden to move the large screen when starting up to prevent the bulb from bursting. Do not cut off the power immediately after use, and the machine will automatically stop after the machine cools down. In addition, it is necessary to minimize the number of frequent switch on and off, so as not to shorten the life of the lamp.
