26、ING DIODE (OLED) DISPLAYS Part 6-1: Measuring methods of optical and electro-optical parameters 1 Scope This part of IEC 62341 specifies the standard measurement conditions and measuring methods for determining optical and electro-optical parameters of organic light emitting diode (OLED) display mod
27、ules, and where specified, OLED display panels, in the following areas: a) luminance and uniformity; b) dark room contrast ratio; c) chromaticity, colour uniformity, colour gamut and white field correlated colour temperature; d) power consumption. 2 Normative references The following referenced docu
28、ments are indispensable for the application of this document. For undated references, the latest edition of the referenced document (including any amendments) applies.

29、ond edition) CIE S 014-1/E:2006, Colorimetry Part 1: CIE Standard Colorimetric Observers 3 Terms, definitions and units For the purposes of this part of IEC 62341, most of the definitions and units used comply with IEC 62341-1-2. 4 Structure of measuring equipment The system diagrams and/or operatin
30、g conditions of the measuring equipment shall comply with the structure specified in each item. 5 Standard measuring conditions 5.1 Standard measuring environmental conditions Measurements shall be carried out under the standard environmental conditions at a temperature of 25 C 3 C, at a relative hu
31、midity of 25 % to 85 %, and pressure of 86 kPa to 106 kPa. When different environmental conditions are used, they shall be noted in the report. 5.2 Standard measuring dark-room conditions With the OLED display turned off, the ambient illuminance at all points on the screen shall be less than 0,3 lx.
32、 When a higher ambient illuminance on the display is present, the background BS EN 62341-6-1:201162341-6-1 IEC:2009 7 luminance measured when the display is OFF shall be subtracted from subsequent luminance measurements of the display, and shall be reported. 5.3 Standard setup conditions Standard se
33、tup conditions are given below. Any deviations from these conditions shall be reported. 5.3.1 Adjustment of OLED display modules The luminance, contrast, correlated colour temperature of the white field, and other relevant parameters have to be adjusted to nominal values and they shall be reported i
34、n detail in the specifications of the measurement. For a full colour display, the chromaticity of the white field shall also be adjusted to match the product specification. When no levels are specified, the maximum contrast and/or luminance level shall be used and the settings reported. These adjust
35、ments shall be held constant for all measurements, unless stated otherwise. It is important, however, to make sure that not only the adjustments are kept constant, but also that the resulting physical quantities remain constant during the measurement. This is not automatically the case because of, f
36、or example, warm-up effects. 5.3.2 Starting conditions of measurements Warm-up time is defined as the time elapsed from the moment of switching on the supply voltage until repeated measurements of the display show a variation in luminance of less than 2 % per minute. Repeated measurements shall be t
37、aken for at least a period of 15 min after starting. The luminance variations shall also not exceed 5 % during the total measurement. Measurements shall be started after the OLED displays and measuring instruments achieve stability. Sufficient warm-up time has to be allowed for the OLED displays to
38、reach luminescence stability. 5.3.3 Conditions of measuring equipment 5.3.3.1 General conditions The following general conditions apply. a) The standard measurement setup is shown in Figure 1. The light measuring device (LMD) may be any of the following meters: 1) a luminance meter with a spectral r
39、esponse approximating the spectral luminous efficiency function for photopic vision; 2) a colorimetric meter with the spectral sensitivity as colour-matching functions for the CIE 1931 standard colorimetric observer (specified in CIE S 014-1); 3) a spectroradiometer with a wavelength range from 380
40、nm to 780 nm; 4) an imaging photometer or colourimeter with the spectral sensitivity as colour-matching functions for the CIE 1931 standard colorimetric observer. Care shall be taken to ensure that the device is capable of performing the required task. b) The light measuring device shall be aligned
41、perpendicular to the area to be measured on the image generating surface of the OLED display. c) The relative uncertainty and relative repeatability of all the measuring devices shall be maintained by following the instrument suppliers recommended calibration schedule.

43、gration time shall be an integer number (10) of one frame period. Shorter integration times are acceptable if the detector is synchronized with the display frame rate. 5.3.3.2 High pixel count matrix displays (320 240 pixels) The following high pixel count matrix applies. a) When measuring matrix di
44、splays, the measurement field shall include more than 500 pixels. b) The standard measuring distance lxois 2,5V (for V 20 cm) or 50 cm (for V 500 pixels) in order to make an accurate luminance measurement. c) Apply a 100 % red drive current to the red sub-pixels and measure the time-averaged current

The area A shall include the emitting sub-pixels and their surrounding dark area. d) Measure the luminance (L) of red emission from the emitting area of the OLED module following the diagram in Figure 1.
