Pay attention to dustproof and ventilation and heat dissipation of the use environment.
As of January 2013, the polysilicon LCD panels used are generally only 1.3 inches, and some are even 0.9 inches, and the resolution has reached 1024X768 or 800X600, which means that each pixel is only 0.02mm, and dust particles are enough to block it. However, because the LCD panel of the projector is fully heat-dissipating, there is usually a special fan to cool it with a flow of tens of liters per minute. The high-speed airflow may also entrain tiny dust particles after passing through the dust filter. They rub against each other to generate static electricity. Adsorbed in the heat dissipation system, which will have an impact on the projection image. Therefore, it is very important to prevent dust in the environment where the projector is used. Smoking must be strictly prohibited, because soot particles are more likely to be absorbed in the optical system. Therefore, clean the dust filter at the air inlet frequently or regularly.
As of January 2013, polysilicon LCD panels are more afraid of high temperatures. Newer models are equipped with temperature sensors near the LCD panel. When the air inlet and dust filter are blocked and the airflow is not smooth, the temperature inside the projector will be rapid. If it rises, the temperature sensor will alarm and immediately cut off the light source circuit. Therefore, it is necessary to keep the air inlet unblocked and clean the filter in time.
For the projector installed on the ceiling, ensure the ventilation and heat dissipation of the upper space of the room. When the projector is suspended, the surrounding environment is often ignored, and the problem of rising hot air is forgotten. The surrounding temperature of the projector working on the ceiling is very different from that below, so this point cannot be ignored.
