PD CEN ISO/TR 9241-308:2015

What is ISO/TR 9241-308 - Ergonomics of human system interaction - SED about?  

ISO/TR 9241-308 is the 308th part of the multiple series that gives guidelines for surface-conduction electron-emitter displays (SED). 

Note 1: Compared with other display technologies, the ergonomic advantages of SED are: 

• Isotropic behaviour of emission of light like that of CRT (cathode ray tube) technology 

• No curvature, unlike CRT technology 
• Fast response time, like CRT technology 
• A uniform and sharp focus on the entire screen as with LCD (liquid crystal display) and PDP (plasma display panel) technologies 

Note 2: The currently known disadvantages of SED are: 

• Limited display size, from 36 inches upwards (with the potential in the future for smaller display size) 

• Fixed resolution compared with CRT technology 

Who is ISO/TR 9241-308 - Ergonomics of human system interaction - SED for?  

ISO/TR 9241-308 on Ergonomics of human-system interaction is useful for: 

• Ergonomics regulation authorities  
• IT companies  

• Offices  
• Hospitals  
• Manufacturers, suppliers and installers of SED based devices 

Why should you use ISO/TR 9241-308 - Ergonomics of human system interaction - SED?  

The surface-conduction electron-emitter display (SED) is a direct-view emissive visual display. 

ISO/TR 9241-308 specifies SED Terms, definitions, symbols, abbreviated terms, SED technology and SED product information for assessment. The ISO/TR 9241-308 incorporates surface-conduction electron-emitter display (SED) technology into the ISO9241 series and international ergonomics standardization.  

Overall, you can use ISO/TR 9241-308 for the collection of preliminary criteria for evaluating the ergonomic features of SED-based devices.
