What is BS EN 61747-2-9:2018?

BS EN 61747-2-9:2018 is a technical standard that specifies the requirements and test methods for passive matrix liquid crystal displays (LCDs) used in electronic devices. It was developed by the British Standards Institution (BSI) and is part of the broader series of standards known as EN 61747, which covers all aspects of LCD technology.

Scope of BS EN 61747-2-9:2018

The standard specifically focuses on passive matrix LCD modules typically found in consumer electronics, industrial control systems, medical equipment, and automotive applications. It provides detailed requirements for the optical, electrical, mechanical, and environmental characteristics of these modules. Compliance with this standard ensures that the quality and performance of LCD displays meet certain industry benchmarks.

Key Requirements of BS EN 61747-2-9:2018

One of the primary requirements of BS EN 61747-2-9:2018 is related to the display's visual quality. The standard specifies parameters such as contrast ratio, brightness, color saturation, and viewing angle, which all contribute to the overall visual experience. Manufacturers must ensure that their LCD modules meet these requirements in order to provide clear and vibrant images to end-users.

In addition to visual quality, the standard also addresses various electrical parameters, including power consumption, response time, and signal stability. These requirements aim to guarantee efficient operation and reliable performance of LCD displays across different operating conditions. By complying with these specifications, manufacturers can ensure compatibility and interoperability with other electronic components.

Testing and Certification

To verify compliance with BS EN 61747-2-9:2018, LCD module manufacturers are required to undergo rigorous testing. This involves performing a series of measurements and assessments according to the specified test methods outlined in the standard. These tests cover aspects such as temperature resistance, mechanical shock, humidity, and durability.

Once the testing phase is complete, manufacturers can seek certification from accredited third-party testing laboratories. The certification confirms that the LCD modules meet the requirements of BS EN 61747-2-9:2018. It serves as proof of compliance and helps build confidence among customers, manufacturers, and regulatory authorities regarding the quality and reliability of the LCD displays.

Conclusion

BS EN 61747-2-9:2018 plays a vital role in ensuring the quality, performance, and interoperability of passive matrix LCD modules. Its comprehensive requirements and testing procedures provide guidance to manufacturers, helping them produce reliable and high-quality products. By complying with this standard, manufacturers can not only meet industry expectations but also gain a competitive edge in the market, ultimately benefiting both businesses and end-users alike.
