BS EN 61747-5:1998

What is BS EN 61747-5 - Liquid crystal display devices about?  

BS EN 61747-5 is the fifth part of a multi-series standard used for liquid crystal display devices.  

BS EN 61747-5 lists test methods applicable to liquid crystal display devices. BS EN 61747-5 takes into account, wherever possible, the environmental test methods outlined in IEC 60068. BS EN 61747-5 also includes visual inspection for both liquid crystal display cells and modules. 

Note 1: This standard is established separately from IEC 60749 because the technology of liquid crystal display devices is completely different from that of semiconductor devices in such matters as: 

• Shape and size 
• Used materials and structure 
• Function 
• Measuring methods 
• Operation principles 

Note 2: Devices include cells and modules. 

Who is BS EN 61747-5 -Liquid crystal display devices for? 

BS EN 61747-5 on liquid crystal and solid-state display devices is useful for 

• Manufacturers of electronic display devices 
• Manufacturers of laser display devices 
• Theatre displays 
• Electronic engineers  

Why should you use BS EN 61747-5 - Liquid crystal display devices?  

A liquid-crystal display (LCD) is a flat-panel display that uses the light-modulating properties of liquid crystals combined with polarizers. 

BS EN 61747-5 specifies the test methods and test procedures for liquid crystal display. The test methods are as follows: 

• Mechanical test method is useful in determining the solderability and bond strength of these displays. This also helps in resisting the robustness of these terminations 
• Environmental and endurance testing method helps in ensuring the durability and sustainability of these displays in different climatic conditions.  
• Miscellaneous test method is helpful in determining the permanence which is useful in cleaning procedures on the devices.  

BS EN 61747-5 helps in inspecting the dimensions, temperature range and requirements of the monochrome matrix liquid crystal displays are appropriate or not. By applying BS EN 61747-5, you can determine the environmental properties that result in manufacturing better image quality liquid crystal displays.
