Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no
longer valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
This part of ISO 9241 introduces surface-conduction electron-emitter display (SED) technology into the
ISO 9241 series and international ergonomics standardization (it is not yet addressed in ISO 9241-307, for
instance, or in other ergonomics standards), and has been developed as a set of initial guidelines for the
assessment of the ergonomic properties of SED-based products.
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, and
⎯ a uniform and sharp focus on the entire screen as with LCD (liquid crystal display) and PDP (plasma
display panel) technologies.
The currently known disadvantages of SED are
⎯ limited display size, from 36 inch upwards (with the potential in the future for smaller display size), and
⎯ fixed resolution compared with CRT technology.
In relation to the ergonomic requirements given in ISO 9241-303 and compared with (for example) CRT, no
other specific health aspects or disadvantages of SED technology had been identified at the time of
publication of this part of ISO 9241.

3 SED technology
3.1 General
The SED panel has a structure as shown in Figure 1. It consists of three main parts: rear plate, face plate and
spacers. The spacers allow a vacuum without change in the confined space and are arranged at an
appropriate distance, d, between the rear and face plates, the accuracy of this distance having no effect on
the SED’s visual ergonomics.

1 face plate 6 rear plate
2 phosphors/metal back film 7 insulator
3 electron emitter 8 scanning wire
4 electrode 9 spacer
5 signal wire 10 luminescence
Figure 1 — SED panel structure
Electrons emitted from surface-conduction electron-emitters (SCE) (see Figures 2 and 3) at a driving voltage,
V, biased between a pair of electrodes, are accelerated by an anode voltage, V . Luminescence from
f a
phosphors is extracted through colour filters. The panel operation is summarized in Figure 2.
