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.
