32 FOREWORD
33 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
34 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
35 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
36 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
37 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
38 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
39 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
40 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
41 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
42 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
43 consensus of opinion on the relevant subjects since each technical committee has representation from all
44 interested IEC National Committees.45 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
46 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
47 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
48 misinterpretation by any end user.49 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
50 transparently to the maximum extent possible in their national and regional publications. Any divergence between
51 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
52 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
53 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
54 services carried out by independent certification bodies.55 6) All users shall ensure that they have the latest edition of this publication.
56 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
57 members of its technical committees and IEC National Committees for any personal injury, property damage or
58 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
59 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
60 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
61 indispensable for the correct application of this publication.62 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
63 rights. IEC shall not be held responsible for identifying any or all such patent rights.
64 International Standard IEC XXXXX has been prepared by IEC technical committee 100: Audio,
65 video and multimedia systems and equipment66 The text of this standard is based on the following documents:

86 INTRODUCTION
88 In nowadays, visual display terminals (VDTs) are everywhere in daily life, such as TVs, monitors,
89 tablets, mobile phones, etc. Almost people will watch VDTs for a long time per day for varies
90 reasons. However, there are three undesirable effects that will be caused by the blue light from
91 VDTs.92 The first one is a possibility of injury to human retina [1]. The energy of blue light emitting from
93 VDTs is weak. However, the effects of long-termexposure (30 years or more) to weak energy
94 from blue light of VDTs are unknown.95 The 2nd one is an effect of disturbance of biological clock (circadian) [2,3]. The blue light
96 emitting from VDTs at nighttime can also cause the disturbance of biological clock.
97 The 3rd one is an effect of eye strain [4,5].98 To reduce these three issues, the demand of blue light reduced VDTs by market is dramatically
99 increasing. In consequence, the industry of VDTs is enthusiastic in promoting blue light reduced
100 VDTs, including well-known companies. On the other hand, the reduction of blue light will
101 certainly have drawbacks on visual experience.102 To address the defects above under the scope of IEC TC100, this project contributes to develop
103 a set of novel measurement methods for VDTs that the methods integrate both the
104 considerations of luminance independent indicators of blue light characteristics (BLCs).
105 NOTICE: this project will only provide objective measurement methods for measuring BLCs of
106 VDTs, the action of defining threshold values or assessment methods are out of the scope of
107 this project. If necessary, manufactures can define their own threshold values and/or
108 assessment methods according to this project.109
