9、1144:2016ISO/TS 21144:2016(E) 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 interes
10、ted 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 C
11、ommission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documen
12、ts should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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

16、1-300 series of International Standards addressed a wide range of visual display tasks and environments and provided the means for evaluating them. Not covered by those standards was the more recently developed electronic paper display (EPD) technology. Owing to its unique optical characteristics, t
17、he current existing measuring methods may not be suitable for evaluating EPD. Until measuring methods and compliance routes for EPD can be developed in the ISO 9241-300 series, this Technical Specification provides intermediate instruction and guidance. Using this Technical Specification together wi
18、th ISO 9241-303 and ISO 9241-305 gives a good understanding of how to analyse an environment for which a specific analysis and compliance method does not yet exist.

19、ndoor use 1 Scope This Technical Specification establishes test methods for evaluating electronic paper display (EPD) when used in indoor tasks and environments. It is intended to be applied together with the measurement procedures of ISO 9241-305 and the generic requirements of ISO 9241-303 to defi
20、ne compliance routes suitable for EPD. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the r

23、ion by diffuse reflection and holds the image with low power consumption 3.2 electronic reader e-reader electronic device which shows information using EPD 4 Electronic paper display for indoor use Display laboratory method 4.1 Intended context of use The attributes of the user, environment, tasks a
24、nd the use of electronic readers based on electronic paper display (EPD) are summarized in Table 1. Attributes are derived from analysis of the intended context of use and are an essential prerequisite for the compliance assessment. Therefore, context elements different from those described in this
25、method could influence the Pass/Fail criteria. TECHNICAL SPECIFICATION ISO/TS 21144:2016(E) ISO 2016 All rights reserved 1PD ISO/TS 21144:2016ISO/TS 21144:2016(E) The supplier shall specify the intended context of use as well as the value or value range of an attribute. The values specified shall ma
26、tch the intended context of use. The intended context of use is part of the compliance report. NOTE 1 Electronic readers with a diagonal of the active display area of up to approximately 7,1 inches (180 mm), corresponding to ISO A6 paper size, and up to 20,2 inches (514 mm), corresponding to ISO A3
27、paper size, are considered in this compliance route for typical visual display tasks for indoor use in work environments. NOTE 2 Automotive environments, such as those of cars, trains and other vehicles, are not addressed here. Table 1 Intended context of use Element Attribute Q u a nt i f ic a t io
28、n User Age and vision User with normal or to normal corrected vision of any age, 7 years or older (any literate user). Environment Design screen illuminance, E S At indoor locations: minimum 20 lx maximum 1 500 lx The supplier shall specify the design screen illuminance (or its range). Typical compo
29、nents of the illu- mination: large aperture source (15) and small aperture source (1) illumination. N/A . There is no evaluation of unwanted reflections. Illuminant For this compliance route CIE illuminant A, D50, D65, F11 and F12 are considered. 5The supplier may specify the intended illuminant. Al
30、l these illuminants exist at every illuminance level of indoors use. Often in combinations. It is assumed that by verifying that the visual display complies in each of the illuminants, the visual display will also comply with any combination of illuminants. The compliance assessment need only be per
31、formed once, with a spectrally broad-band laboratory illumination. The compliance calculations are then made using spectral cal- culations and repeated for each of the specified illumina- tion levels and illuminants. Ambient temperature For this compliance route an ambient temperature of approximate
32、 15C to 35C is considered, if not otherwise specified by the supplier.2 ISO 2016 All rights reservedPD ISO/TS 21144:2016ISO/TS 21144:2016(E) Element Attribute Q u a nt i f ic a t ion Task Content and perception For this compliance route the following contexts for perception of information are consid
33、ered, if not otherwise specified by the supplier. A r t i f ic i a l i n f or m a t ion Visualization of objects and scenes that do not have origi- nals in our world, e.g. text (i.e. alphanumeric characters), graphical signs, symbols, etc. in monochrome (including achromatic) and/or multicolour (inc
34、luding full-colour) presentation. The Pass/Fail criteria may contain three different require- ment levels, “High”, “Medium” and “Low”, which determine the degree to which a criterion is fulfilled: “High” for visual display tasks require high performance in e.g. colour gamut, grey scale but also high
35、er comfort regarding character attributes; “Medium” for general visual display tasks require suf- ficient performance to perceive colour and to read the information without discomfort by the user; “Low” for visual display tasks require low performance in e.g. colour gamut and grey scale, but with su
36、fficient performance to read the information without discomfort by the user.Amount of information Preferred screen size for sufficient amount of information with appropriate object size and resolution.Image type For this compliance route the visual display shall be capa- ble of displaying still and
37、quasi-static images.Design viewing distance, D design,view The minimum design viewing distance, D design,view,min , is 200 mm. The supplier shall specify D design,view .Design viewing direction, D , D Within a specific range of angles from the normal. For this compliance route, perpendicular viewing
38、 direction is assumed, if not otherwise specified by the supplier. Therefore, the default design viewing direction, ( D , D ), is (0, ).Table 1 (continued) ISO 2016 All rights reserved 3PD ISO/TS 21144:2016ISO/TS 21144:2016(E) Element Attribute Q u a nt i f ic a t ion Task Design viewing direction r
39、ange (angle of inclination and azimuth) For this compliance route, a design viewing direction range of up to 80 is considered, if not otherwise specified by the supplier (as shown below). Therefore, the maximum angle of inclination, , is 40. The azimuth angle, , is 0 to 360 Eye and head position Fro
40、m fixed to moving. Number of users Typically single. Usage Display handling For this compliance route, stationary and portable display handling is considered, unless otherwise specified by the supplier. 4.2 Information about the technology The basic physical attributes of electronic readers are give
41、n in Table 2. The supplier shall submit a detailed technical specification which includes rated voltage, rated frequency, rated current, rated power consumption, panel specification, horizontal/vertical pixel size, original resolution, sub-pixel drawing, anti-reflection treatment, pixel fault declar
42、ation, prepared gamma-value, and factory setting of brightness, contrast, colour control. The supplier shall also submit the test pattern, if required.Table 1 (continued) 4 ISO 2016 All rights reservedPD ISO/TS 21144:2016ISO/TS 21144:2016(E) Table 2 Basic physical attributes of the visual display Ba

45、 omplianc e assessment The compliance assessment shall be given according to Tables 3 to 13. Electronic paper displays for electronic readers are used in a wide variety of illumination conditions. The darkroom or laboratory illumination condition can vary greatly from actual usage conditions. The ap
46、proach of this compliance route is to perform the measurements under stable laboratory conditions with darkroom and laboratory light source illumination and then convert by calculation to the contexts of use prescribed by the compliance route. Unless otherwise explicitly defined, a requirement is me
47、t only if it is met for all illuminance levels and illuminants defined in the intended context of use. Table 3 Viewing conditions Attribute Pass/Fail criteria based on requirements and intended context of use Measuring method Assessment and reporting Design viewing distance The design viewing distan
48、ce is a) for children, a minimum of 200 mm; b) for adults, a minimum of 300 mm; c) for elderly people, a minimum of 450 mm.
