20、 Part 1-1: Terminology and letter symbols FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all q
21、uestions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publicat
22、ion(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC c
23、ollaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opini
24、on on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to en
25、sure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently
26、to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certificat
27、ion bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall at
28、tach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fe
29、es) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publicat
30、ion. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62715-1-1 has been prepared by IEC technical committee 110:
31、 Electronic display devices. The text of this standard is based on the following documents: CDV Report on voting 110/441/CDV 110/480A/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been draf
32、ted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 62715 series, under the general title Flexible display devices, can be found on the IEC website. 4 62715-1-1 IEC:2013 The committee has decided that the contents of this publication will remain unchanged until
33、the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 62715-1-1 IEC:2013 5 FLEXIBLE DISPLAY DEVICES Part 1-1: Terminology
34、 and letter symbols 1 Scope This part of IEC 62715 gives the preferred terms, their definitions and symbols for flexible display devices, with the object of using the same terminology when standards are prepared in different countries. 2 Terms and definitions For the purposes of this document, the f
35、ollowing terms and definitions apply. 2.1 Classification of terms Terms for flexible display devices were classified as follows: general terms (2.2) terms related to physical properties (2.3) terms related to constructive elements (2.4) terms related to performances and specifications (2.5) terms re
36、lated to the production process (2.6) 2.2 General terms 2.2.1 flexibility mechanical pliancy to an external mechanical stress 2.2.2 flexible display device flexible display panel and flexible module that are mechanically bendable in one or more of the steps of substrate handling, manufacturing, stor
37、age, use, operation, shipping, and relocation Note 1 to entry: Preferably, flexible display devices are bendable, compliable to curved surface, rollable, or foldable without creasing. Note 2 to entry: Flexible display devices are generally rugged under rough handling. 2.2.3 flexible display module f
38、lexible display device that has external drivers, optical films and other input/output interactive films such as touch screen or sensing films 2.2.4 flexible display panel flexible display device without external drivers 2.2.5 flexible display product which contains flexible display modules and whic
39、h is bendable for end users 6 62715-1-1 IEC:2013 2.3 Terms related to physical properties 2.3.1 malleability ability of flexible display devices to deform under compressive stress and to keep the deformed shape after releasing the stress 2.3.2 flexural strength maximum bending stress that can be app
40、lied to flexible display devices without causing any deterioration of image quality, permanent distortion or breakage 2.3.3 flexural modulus ratio of bending stress to the resulting strain in flexural deformation of flexible display devices 2.3.4 cyclic stress repetitive application of an external s
41、timulus, such as mechanical force or exposure to temperature, to flexible display devices over time Note 1 to entry: In case of mechanical cyclic stress, it is typically called “fatigue.“ 2.4 Terms related to constructive elements 2.4.1 gas barrier layer type of passivation layer that hinders contam
42、inants in vapour or gaseous forms, from transmitting into the active device area Note 1 to entry: The gas barrier layer is typically employed on substrates or directly on the active device to prevent water or oxygen from permeating into the active device area. 2.4.2 flexible substrate substrate with
43、 flexibility where the flexible display device is composed on, such as plastic film, thin glass, metal foil, or paper 2.4.3 buffer layer type of passivation layer that is inserted between the substrate and electronic elements of the flexible display device to mitigate the defect effect on the displa
44、y fabrication process and/or the operation performance Note 1 to entry: The buffer layer is typically employed on a thin glass substrate to hinder breakage when subject to a bending. 2.4.4 insulation layer type of passivation layer that electrically separates the metal foil substrate from the conduc
45、tive part of a device Note 1 to entry: It can be applied to a substrate surface to create a smooth surface. 2.5 Terms related to performances and specifications 2.5.1 bending radius radius of arc corresponding to the curvature of the central line between innermost and outermost surfaces of a flexibl
46、e display device during a bending test 62715-1-1 IEC:2013 7 2.5.2 critical bending radius minimum bending radius at which a flexible display device operate without causing any deterioration of image quality, permanent distortion or breakage 2.5.3 strain ratio of the amount of change in the length of

48、f the substrate is measured by monitoring changes in the optical transmission or electrical property of the calcium layer. The calcium layer is degraded due to the permeation of moisture or other gases through the substance. Note 2 to entry: The time dependence of the calcium change process is inver
49、sely proportional to the permeation rate. 2.6 Terms related to the production process 2.6.1 carrier substance to which a flexible substrate is temporarily attached for handling purposes during display fabrication process 2.6.2 carrier lamination attachment of flexible substrates to carriers by gluing them with heat and/or pressure 2.6.3 carrier delamination detachment of the laminated substrates or fabricated flexible display devices f
