Introduction to waterproof rating of bar stretched LCD digital screen

As a widely used commercial device, bar LCD screens are used in retail, transportation, industry and other fields, covering indoor and outdoor environments. In order to prevent the screen from working normally and maintaining good display effects when encountering rain, humid air or splashing water during use, different waterproof levels are set according to different needs. Its waterproof design is not only related to the durability of the device, but also to the normal operation of the device. If the LCD screen encounters water vapor or water penetration, it may cause the screen circuit to short-circuit, display failure, or even complete failure. Therefore, understanding its waterproof technology can help manufacturers make solutions that are more suitable for various environments when designing, and can also help users choose suitable equipment according to their needs.

Ingress Protection Rating is an international standard for evaluating the dust and liquid protection capabilities of electronic devices. Its abbreviation is IP rating. These two letters have meanings. The former represents dustproof capability and the latter represents waterproof capability, which directly affects the adaptability of electronic devices in different environments.

The waterproof level (the second number after IP) ranges from 0 to 8. The larger the number, the stronger the device's ability to protect against water. The following is a detailed description of each waterproof level.

Description: The device has no waterproof protection and cannot prevent water intrusion at all. It is suitable for indoor environments and occasions where the risk of the device being exposed to water sources is low.

Description: The device can withstand water drops within a tilt of 15 degrees. Even if the device is slightly tilted, water drops will not penetrate into the device. It is suitable for places with flexible installation angles or easy tilting.

Description: The device can withstand water spray from a range of 60 degrees, which means that the device can prevent light water mist or spray droplets from entering the device in certain areas or environments.

Description: The device can withstand splashing water from any direction, that is, water can splash in from all directions without causing damage to the device. It is suitable for environments with high humidity but not direct contact with water, such as kitchens and bathrooms.

Description: The device can withstand water jets from any direction and is suitable for environments that may be impacted by strong water jets, such as outdoor advertising displays, outdoor traffic displays, etc.

Description: The device can withstand strong water flow without damage, and will not affect the normal operation of the device even in a high-intensity water flow environment. Suitable for outdoor use, especially in heavy rain or extreme weather.

Description: The device can be immersed in water at a depth of 1 meter for 30 minutes without being damaged. This level is suitable for devices that are occasionally or briefly exposed to water, such as waterproof advertising screens, outdoor display screens, etc.

Description: The device can be immersed in water more than 1 meter deep without any damage. This waterproof level is usually used for underwater devices or devices that work for a long time in high humidity environments.

Description: This rating means that the device can be immersed in water for a long time without any impact while being completely dustproof. The device's waterproof and dustproof capabilities meet the highest standards in the industry and are suitable for use in extreme environments, such as underwater detection equipment, traffic lights, outdoor advertising equipment, etc.

The waterproof requirements in indoor commercial environments are usually relatively small because they will not directly encounter a large range of water sources, but there may still be slight splashing water, air humidity, and water flow during cleaning that affect the overall equipment. The waterproof level is mainly considered based on these situations. For example, in retail stores, shopping malls, supermarkets, hotel lobbies and other places, if there are no special requirements, IPX4 to IPX6 waterproof levels are sufficient.

The waterproof requirements for LCD bar screens in outdoor commercial environments are significantly higher, because the outdoor environment needs to directly face adverse weather conditions, such as heavy rain, strong winds, dust, snow and other extreme weather conditions. Deploying bar stretched LCD digital signage in outdoor public places needs to be able to cope with strong water flow impact and long-term water exposure. Therefore, IPX5 to IPX7 waterproof levels are necessary. The specific level required needs to take into account whether there are obstructions or weather conditions in previous years.

Choosing the right waterproof level can not only increase the service life of stretched LCD digital screen in a specific environment, but also effectively reduce the cost of repair and maintenance, and reduce the risk of equipment damage. Therefore, understanding and correctly selecting the waterproof level to ensure that the LCD strip screen can operate stably in various environments is an important factor that every company must consider when selecting equipment.
