13、t methods of touch displays Environmental durability test methods 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 internation
14、al co-operation on all questions 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 refe
15、rred to as “IEC Publication(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
16、 this preparation. IEC collaborates 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 internat
17、ional consensus of opinion 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 reasonabl
18、e efforts are made to ensure 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 Pub
19、lications transparently 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
20、. Independent certification 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.
21、7) No liability shall attach 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 c
22、osts (including legal fees) 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 appl
23、ication of this publication. 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 629081310 has been prepared by IEC
24、technical committee TC 110: Electronic display devices.

BS IEC 62908-13-10:2016 6 IEC 62908-13-10 IEC 2016 INTRODUCTION This part of IEC 62908 was developed in response to the demand for standardization of the test methods for the endurance of touch displays. The touch display is one of the most important interfac
29、es between a user and a display. Various technologies for touch displays have been developed, and it is expected that touch display technology will make rapid progress in the future. This document is especially effective for capacitive and resistive touch displays. Durability is one of the most impo
30、rtant aspects of touch display modules. Touch displays connected to display modules are used under a variety of environmental conditions, including indoor/outdoor, hot/cold, dry/humid, for long periods of time and may be subjected to severe environmental stress. This document describes standardized
31、test methods to evaluate the durability of touch displays subjected to environmental stresses. It is valid for research and development, quality assurance, and comparison of devices when making purchasing decisions.

32、t 13-10: Reliability test methods of touch displays Environmental durability test methods 1 Scope This part of IEC 62908 specifies the methods for testing the environmental durability of touch display modules, touch sensor modules and test pattern cells, and can be used for devices at the production
33、 level, the prototype level or the trial model level when they are exposed to environmental stress. This document is applicable for touch displays that use capacitive or resistive detection sensors. It may also be applicable to other types of sensors as well as to touch display modules with both fla
34、t and flexible displays. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

A specific circuit pattern that is appropriate for the purpose of the test may be created for the test, as shown in Figu
48、re 1. For example, the line width of the circuit pattern is 50 m, and the distance between lines is 500 m. The power supply should be the pulse wave. The applied pulse wave should be appropriate for the purpose of the test. An example of the applied pulse wave is shown in Figure 2. Figure 1 Example
49、setup of test pattern cell NOTE V is the voltage of the applied pulse wave, T is the period, and t is the pulse duration. The duty ratio percent is calculated by t/T 100.
