DLP rear projection splicing large screen maintenance problem

The DLP large screen is currently the inevitable choice for many occasions where the details of the monitor screen are high and the project is grand. The seamless stitching technology and visual effects ensure the accurate display and perfect effect of the large screen image. But, do you know how to maintain the DLP big screen?

As we all know, DLP is digital light processing, which means that this technology first digitally processes the image signal and then projects the light. It is based on the digital micromirror component developed by TI (Texas Instruments, USA) - DMD (Digital Micromirror Device) to complete the display of visual digital information. In order to achieve the expected life of DLP large screen and maintain stable operation, Clear Screen Video reminds you that you can operate and maintain according to the following methods:

Maintenance of optical equipment

The screen is placed in an easily ventilated area to prevent dust and heat. There is a heat dissipation system in the DLP box, but the high-speed airflow is still absorbed by the dust in the heat dissipation system, and the dust gathers inside the large-screen optical device, which will affect the picture quality. In use, pay attention to the dust and smoke of the screen, and clean the filter net regularly.

The DLP large screen uses UHP light source, and the lamp life is related to the screen quality and service life. In use, it is strictly forbidden to move the large screen when starting up to prevent the bulb from bursting. After use, do not cut off the power immediately, and let the machine stop automatically after cooling. In addition, it is necessary to minimize frequent switching, so as not to shorten the lamp usage time.

Regularly clean the large-screen optical device to increase the brightness and contrast of the large-screen display system (10% to 30% increase). In use, pay attention to the maintenance of daily optical components (color wheel, liquid crystal panel, polarizing plate, lens, etc.) to prevent premature aging.

Precautions during installation and use

When the machine is moving, it should be handled with care, shockproof, rigorous collision, squeezing and vibration. During the installation process, only one screen can be moved at a time to avoid bruising of other screens. On the screen surface cleaning, be careful to use a soft cloth to wipe, do not use hard things to wipe the screen or use chemical cleaning agents to clean. When your screen is not in use for a long time, you should turn off the power.
