DLP large screen splicing display system in the high-end display industry applications are quite common, and the market demand is also growing, large screen splicing technology is generally used in large-scale command center system, public security, transportation, troops, medical, government, multi-party tele-vision conference. But our customers on the large screen display system knowledge and technology are too little understanding, so lead to the use of the process of many accidents, on the big screen caused a lot of some fatal injuries.
A, DLP large screen display optical equipment failure and bulb service life shortening reason analysis
1, DLP large screen display optical equipment surface air inlet over the net is not timely cleaning.
2, the outside world can not completely cool air into the machine, directly affecting the internal heat dissipation DLP large screen optical equipment.
3, even if the large screen optical equipment air inlet to do timely cleaning, but due to the large screen optical equipment itself cooling needs, from the air inlet with the air into some of the dust, a long time, the large screen optical equipment will be gathered inside a large amount of dust. Resulting in large-screen optical equipment cooling fan speed slowed down, affecting the large-screen optical equipment internal heat dissipation.
4, dust gathered on the optical path, the projector brightness is greatly reduced, the image is blurred, but also affects the projector optical components of their own heat dissipation, resulting in damage to the optical components (LCD panels, polarizing panels, etc.).
5, the user non-correct operation, such as closing the large screen optical equipment directly after cutting off the projector power.
Second, how to do regular maintenance on the DLP screen optical equipment
1, the large screen optical equipment to easy ventilation in the environment, to improve the service life of the large screen optical equipment bulb.
2, regularly on the big screen optical equipment to do a comprehensive cleaning process, can improve the large screen display system brightness and contrast (10% to 30%).
3, when the temperature is very low, it will affect the normal use of the outdoor screen, generally below -30 degrees Celsius, it is recommended to temporarily stop using. Of course, other measures such as the installation of air conditioning in the box, can also ensure normal use.
4, pay attention to the daily maintenance of optical components (color wheel, LCD panel, polarizing plate, lenses, etc.) to prevent premature aging.
