LCD enclosure on outdoor screen prevents air Circulation

Currently, you will notice that LCDs are installed outdoor and used for brand, awareness, marketing, and advertising. There is an increase in demand for more people who request an electric patio screen. However, most good things in the market usually come with various setbacks, and also several challenges commonly face the outdoor screen. Here are some of its common errors:


Protection is one of the common setbacks that regularly experienced during outdoor screen installation. The installer must ensure that the device is perfectly protected from hostile weather with a waterproof screen or plasma enclosure. However, even though they are trying to protect the TV from water, they forget that the display also requires free air circulation.

Air circulation is usually essential for most electronic devices, including an outdoor screen device, since it also generates heat. So, the manufacturer typically makes sure that the heat is blown out of the components to prevent overheating. The issue may become worse if you cover the screen with a signage enclosure.

It is commonly done when the Plasma enclosure offers waterproof protection, mainly when the device is operated outside the house. So, the heat will build up when it is covered by an LCD enclosure trying to prevent water from penetrating inside the device.

How to manage air circulation in the device

Since air accumulation is expected in the screen, especially when it is covered with an LCD enclosure, a suitable LCD enclosure should come with enough air circulation systems around to allow free air inside the device. However, air circulation also causes some issues on an LCD enclosure.

But to make sure the LCD doesn’t allow water to penetrate inside the device elements, the LCD enclosure should have free air vents to allow free air circulation. However, another danger of air circulation vents is that they may allow water to penetrate the screen, and eventually, the screen can be damaged.

Preventing water from getting through the LCD enclosure

The most common solution to preventing water from penetrating through an LCD enclosure is to create air vent below the enclosure. Therefore, it will only allow air circulation below the screen, but water cannot.

However, the device is still exposed to more setbacks since the splashes have the potential of getting through the enclosure through the zigzagged chimney. So, to prevent this issue, the plenum chamber is always added to minimize the open spaces that may allow water into the device.


When the device doesn’t have enough air circulation, it may result in overheating that may eventually damage the screen. Especially sensitive devices like electric patio screens that are exposed to excess heat are typically at high risk of damage due to high temperature. Therefore, air circulation should always be considered in the device.
