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

BS EN 61747-2-9:2018 is a technical standard that specifies the requirements and testing methods for active matrix liquid crystal display (AMLCD) modules. This standard covers various aspects such as mechanical, environmental, optical, electrical, and interface characteristics of AMLCD modules. It is an essential guideline for manufacturers, suppliers, and users of these modules to ensure their quality and performance.

Mechanical Requirements

The mechanical requirements outlined in BS EN 61747-2-9:2018 include specifications for the module's dimensions, surface flatness, and mounting method. The standard provides guidelines on the allowable tolerances for these parameters to ensure compatibility with electronic components and systems. It also addresses factors like shock resistance, vibration resistance, and durability, which are crucial for the module's reliability in various applications.

Environmental Testing

In order to assess the module's resilience to different environmental conditions, BS EN 61747-2-9:2018 sets out a range of tests. These tests evaluate the module's ability to withstand exposure to heat, cold, humidity, and mechanical stress. They also examine its resistance to dust, moisture, and chemicals. By subjecting the module to these tests, manufacturers can ensure that it can operate reliably under diverse environmental conditions.

Electrical and Optical Characteristics

The standard defines the electrical and optical characteristics of AMLCD modules, providing precise guidelines for parameters like power consumption, operating voltage, response time, contrast ratio, brightness, and color performance. These specifications help manufacturers design and produce modules that meet the requirements of specific applications, ensuring optimal performance and compatibility with electronic systems.

Interface Requirements

BS EN 61747-2-9:2018 also addresses the interface requirements for connecting the AMLCD module to other electronic components. It specifies the electrical and mechanical characteristics of the module's input and output interfaces, ensuring compatibility with industry-standard connectors and signaling protocols. This allows seamless integration between the module and other components in a larger system, facilitating reliable communication and functionality.

Overall, BS EN 61747-2-9:2018 plays a vital role in standardizing the quality and performance of AMLCD modules. By adhering to this technical standard, manufacturers can ensure that their products meet the necessary requirements, giving customers confidence in their reliability and usability.
