How to choose a suitable anti vibration industrial LCD screen?
In industrial environments, vibration is a major challenge faced by LCD screens. The key to choosing a suitable anti vibration industrial LCD screen is to understand the technical principles behind it and comprehensively consider multiple dimensions such as structure, connection method, and performance parameters. Here is a detailed selection guide, hoping to help you make wise decisions.
Grasp the core of structure and connection
In a vibrating environment, the internal structure and connection method of the LCD screen directly determine its durability.
Preferred COG structure: For the driving chip of LCD screens, COG (Chip on Glass) structure is a more reliable choice because it directly binds the driving chip to the glass. This built-in method performs better in terms of shock resistance than the COB (Chip on Board) structure with external driver chips.
Reliable connection interface: In terms of connection method, metal pins (directly soldered to the circuit board) and soldered FPC cables can effectively resist the risk of loosening caused by vibration due to their strong connection characteristics. Try to avoid using plug-in FPC as much as possible. If it is necessary to use it, be sure to choose high-quality connectors and consider reinforcing them through processes such as gluing.
Focus on key performance and protection indicators
In addition to the core structure, the following performance parameters are also crucial for stable operation in vibration and other harsh environments:
Brightness and visibility: Industrial environments have complex lighting conditions and require high brightness to ensure clear visibility. It is recommended to choose a screen with a brightness of 500 cd/m ² or higher for indoor environments, and some industrial applications even require a brightness of at least 450 cd/m ². Meanwhile, high contrast (e.g. 450:1 or higher) and wide viewing angle (up to 178 °) are crucial for obtaining information in strong light or special angles.
Backlight lifespan and wide temperature operation: Industrial equipment often requires long-term uninterrupted operation, and the backlight lifespan should reach at least 50000 hours. In addition, the working temperature range should be wide, and some high-quality industrial LCD screens use wide temperature LCD materials that can adapt to extreme temperatures ranging from -40 ℃ to+85 ℃.
Robust physical protection: The protection level is a standard for measuring the dust and water resistance of equipment. In industrial environments, the front panel should reach at least IP65 level (dust and waterproof column impact). At the same time, pay attention to the anti vibration and anti impact parameters of the product. For example, some products can withstand vibrations with amplitudes of 5-19Hz/1.2mm, accelerations of 19-200Hz/1.2g, and impacts with accelerations of 15g.
Consider the long-term guarantee of brand and service
In the industrial field, the long-term stability of products and the reliability of the supply chain are equally important.
Industrial grade reliability: Prioritize brands and products designed specifically for industrial environments. These products typically have stricter commitments in terms of configuration control (ensuring compatibility over a certain period of time) and product lifecycle (industrial grade displays typically have a stable supply period of 3-5 years), which can avoid trouble caused by frequent product changes or shutdowns.
Supply Chain and Support: Choose suppliers who can provide sound Product Change Notification (PCN) and End of Life (EOL) plans, which can give you sufficient time to respond to product updates. Meanwhile, it is crucial to understand whether the supplier provides spare parts support (such as replaceable backlight components) and maintenance services to ensure the long-term stable operation of the equipment and reduce maintenance costs.
Summary and selection steps
In general, when choosing an anti vibration industrial LCD screen, you can follow the following steps:
Analyze the usage environment: clarify the frequency and intensity of vibration, as well as other environmental factors such as temperature, humidity, dust, etc.
Determine key parameters: Based on environmental analysis, determine the required brightness, contrast, protection level, operating temperature range, and specific requirements for shock/vibration resistance.
Internal structure verification: Prioritize LCD screens with COG structure, metal tube pins, or soldered FPC connections.
Choose a reliable supplier: Assess the industry reputation of the brand, confirm whether its product lifecycle, configuration control strategy, and after-sales service system meet the needs of industrial applications.
I hope this guide can help you choose an industrial LCD screen that is both durable and meets your application needs. If you could share more information about the specific usage scenarios of the equipment (such as whether it is used for heavy machinery, vehicle systems, or automated production lines), perhaps I could provide more targeted advice.
