PmeasuredStandard dynamic range (SDR) on-mode, "normal" | Power measurement notes(See Annex IIIa for informative notes regarding the testing of Displays with a standardised DC input or a non-removable battery providing the primary power. For the purposes of these Transitional Measurement Methods a standardised DC input is solely one compatible with the various forms of USB power delivery.Video Signals NotesThe 10-minute Dynamic Broadcast video sequence described in existing relevant standards shall be replaced with an updated 10-minute Dynamic Broadcast video sequence. This is available for download at: https://circabc.europa.eu/ui/group/1582d77c-d930-4c0d-b163-4f67e1d42f5b/library/23ab249b-6ebc-4f45-9b0e-df07bc61a596?p=1&n=10&sort=modified_DESC. Two files are available, in SD and HD. They are respectively titled "SD Dynamic Video Power.mp4", and "HD Dynamic Video Power.mp4". SD resolution is made available for the limited types of display that cannot accept or display higher resolution standards. The HD resolution file is used for all other display resolutions since this closely matches the average picture level (APL) of the current IEC HD dynamic broadcast dynamic test sequence described in existing relevant standards.Upscaling from HD to higher native resolution shall be performed by the Unit Under Test (UUT) and not by an external device. Where upscaling has to be performed by an external device the full details of the device and the signal interface with the UUT shall be recorded.The data signal from the downloaded file storage system to the UUT digital signal interface shall be confirmed to provide peak white and full black video levels. If the file playback system has special picture optimisation features (e.g. deep blacks or enhanced colour processing) these shall be disabled. For repeatability of measurement purposes, the details of the file storage and playback system shall be recorded as well as the type of digital interface with the UUT (e.g. HDMI, DVI etc.) The power measurement P measured is an average value from the full 10-minute length of the dynamic test sequence, taken with ABC disabled. |
PmeasuredHigh dynamic range (HDR)on-mode "normal"(auto mode switching to HDR) | No existing relevant standard is published so far.Following the Pmeasured (SDR) dynamic test sequence measurement two HDR dynamic test sequences shall be played.These 5-minute sequences are rendered in HD resolution only, in the common HDR standards of HLG and HDR10. Upscaling from HD to a higher native display resolution shall be performed by the UUT and not an external device. Where upscaling has to be performed by an external device the full details of the device and the signal interface with the UUT shall be recorded.These files are available for download at: https://circabc.europa.eu/ui/group/1582d77c-d930-4c0d-b163-4f67e1d42f5b/library/38df374d-f367-4b72-93d6-3f48143ad661?p=1&n=10&sort=modified_DESCand have identical programme content. The files are respectively titled "HDR-HLG Power.mp4" and "HDR_HDR10 Power.mp4"It is essential that the UUT switch to the HDR display mode is confirmed in the picture settings menu before power data is logged. The integrated power measurement for each sequence (Pav) shall be summed and halved for the calculation of the label HDR energy efficiency class and label HDR power declaration.If the UUT cannot be tested in one of these HDR formats, this shall be noted and the power declared shall be the Pav measured for the HDR format that is supported.An ABC allowance does not apply in HDR display mode.Pmeasured HDR = 0.5 * (Pav HLG + Pav HDR10)If one of these HDR display modes is not supported, the measured numerical value of (Pav HLG) or (Pav HDR10) as appropriate, shall be used for Label VII and Label VIII declarations. |
Screen Luminance Measurement for automatic brightness control (ABC) control characteristics evaluation and any other peak white luminance measurement requirement. | No existing relevant standards can be used.A new variant of the "box and outline" dynamic test pattern providing a dynamic format with colour shall be used for all peak white display luminance measurements and not the 3-bar black and white pattern.A set of these variant dynamic test patterns, which combine the box and outline format and VESA L10 to L80 white measurement box format shall be used as described in Section 1.2.4. of Annex IIIa and are available for download at: https://circabc.europa.eu/ui/group/1582d77c-d930-4c0d-b163-4f67e1d42f5b/library/4f4b47a4-c078-49c4-a859-84421fc3cf5e?p=1&n=10&sort=modified_DESC. They are contained in the subfolders labelled SD, HD and UHD. Each subfolder contains eight peak white dynamic test patterns from L10 to L80. A resolution may be chosen according to the native resolution and signal compatibility of the UUT. The selection of a pattern with the appropriate resolution shall be based upon a) the minimum required white box dimensions for correct operation of the contact luminance measuring instrument and b) the fact that no power limiting effect exhibited by the UUT (large areas of white may result in a reduction of peak white levels). Any upscaling shall be performed by the UUT and not an external device. The data signal from the downloaded file storage system to the UUT digital signal interface shall be confirmed to provide peak white and full black video levels and have no other video enhancement processing (e.g. deep blacks / colour enhancement) Both the storage system and signal interface type shall be noted. For displays tested using a USB, or USB compatible data interface with the feature of power delivery, both the UUT and USB connected signal source shall operate from their own power source with the data path only connected.. |
Measurements related to ABC for "Allowances and adjustments for the purposes of the EEI calculation and functional requirements" | The methodology for ABC ambient light source set-up and luminance control as specified in existing standards shall not be used for the purposes of ABC related measurements for this regulation. The methodology to be used is detailed in Section 1.2.5. of Annex IIIa. |
Peak white luminance ratio | No existing relevant standards can be used.The "box and outline" dynamic test pattern selected for the ABC peak white luminance measurements (Annex III.a Section 1.2.4) shall be used to measure the peak white luminance of the "normal configuration" with ABC on. If this is less than 150 cd/m2 for monitors or 220 cd/m2 for other display products, then a further measurement shall be made of the peak white luminance of the brightest pre-set configuration in the user menu (not the shop configuration). ABC need not be on for the luminance ratio measurements but the status of the ABC (on or off) shall apply to both measurements. Where ABC is on, the illuminance shall be 100lux for both measurements. Care shall be taken to ensure that the dynamic test pattern selected for peak white luminance measurement in the "normal configuration" does not cause luminance instability in the brightest pre-set configuration. A smaller peak white box pattern shall be selected for both measurements if instability occurs. |
