What protection ratings are required for industrial LCD screens?
The protection level of industrial LCD screens is typically based on the IP (Ingress Protection) rating, which consists of two digits representing the resistance to solid foreign objects (such as dust) and liquids (such as water), respectively.
The table below summarizes common protection ratings in industrial environments and their applicable scenarios, allowing for quick reference.
IP rating | Protection Capability Description | Typical application scenarios |
IP54 | -Dust prevention: Although it cannot completely prevent dust from entering, the amount of dust entering will not affect the normal operation of the equipment. -Waterproof: It can resist splashing water from any direction. | Suitable for indoor environments such as general office buildings, retail stores, restaurants, etc., used as a self-service inquiry desk or cash register. |
IP65 | -Dustproof: Completely prevent dust from entering. -Waterproof: It can withstand low-pressure water jets from any direction. | Widely used in scenarios such as factory automation, light industrial environments, outdoor control panels, etc. where dust is present or equipment cleaning is required. |
IP67 | -Dustproof: Completely prevent dust from entering. -Waterproof: Can be submerged in water for a short period of time (usually 1 meter deep, lasting for 30 minutes). | Suitable for environments that may encounter accidental immersion or require regular flushing, such as food processing, mining monitoring, outdoor equipment, etc. |
IP68 | -Dustproof: Fully sealed to prevent dust. -Waterproof: It can be immersed in water for a long time under certain pressure, and the specific depth and time are specified by the manufacturer. | Used in extreme environments, such as ship control consoles, sensors for long-term underwater work, etc. |
How to choose protection level based on the scene
When making a choice, the key is to evaluate your actual usage environment:
Indoor cleanliness/general commercial environment (such as offices, museums): IP54 rating is usually sufficient, as it can effectively protect against daily dust and accidental splashes of water.
Industrial and outdoor harsh environments: Requires at least IP65 or higher rating.
If there is high-pressure water mist in the environment or equipment cleaning is required (such as food and beverage processing, workshop cleaning), IP65 or IP66 is recommended.
If the device may experience brief immersion (such as falling into a puddle or being submerged by rainwater), IP67 should be selected.
For equipment that requires long-term underwater operation, an IP68 rating must be selected.
In addition to IP rating, it is also important to pay attention to these
In industrial applications, focusing solely on IP rating is not enough, the following points are equally important:
Wide temperature working ability: Ensure that the LCD screen can operate stably in high and low temperature environments on site. Industrial grade products typically require support for a wide temperature range of -30 ℃ to+80 ℃.
High brightness and anti glare: In outdoor or strong light environments, a screen with high brightness (≥ 700 cd/m ²) and anti glare coating is required to ensure clear visibility.
Anti vibration and anti impact: In places with frequent vibrations such as mines and construction machinery, screens need to have good anti vibration performance to ensure that the internal structure is not loosened or damaged due to vibration.
Touch mode: In environments where gloves are required for operation or where the screen surface is prone to oil and water stains, resistive touch screens are a more reliable choice.
I hope the above information can help you make a suitable choice. If you can tell me the specific usage scenarios of the LCD screen (such as outdoor advertising, food processing workshops, or mining machinery), I can provide you with more specific selection suggestions.
