Note: DOE has updated the test setup for dc-powered Displays to measure the dc power directly. In theprevious revision, measured power of dc-powered Displays included the power consumed by a dc source(i.e., USB hub or similar device). Because the powered dc source is not necessarily included with the
product, a direct dc power measurement is more representative of the energy used by such Displays.
DOE requests comment on the specified test method.

108
109

I)

Light Measuring Device (LMD):
1) Luminance measurement shall be performed using either

110a) A contact meter; or

111b) A non-contact meter.

1122) All LMDs shall meet the following specifications:

113a) Accuracy: ± 2% (± 2 digits) of the digitally displayed value

114b) Acceptance Angle: 3 degrees or less

115
116
117
118
119
120
121
122

The overall accuracy of LMDs is found by taking (±) the absolute sum of 2% of the targeted
illuminance and a 2 digit tolerance of the displayed value least significant digit. For example, if the
LMD displays “200.0” when measuring a screen brightness of 200 nits, 2% of 200 nits is 4.0 nits. The
least significant digit is 0.1 nits. “Two digits” implies 0.2 nits. Thus, the displayed value would be 200± 4.2 nits (4 nits + 0.2 nits).The accuracy is specific to the LMD and shall not be considered as
tolerance during actual light measurements. Light measurement accuracy shall be within thetolerance specified in 4.J)4).
J) Measurement Accuracy:

123
124

1) Power measurements with a value greater than or equal to 0.5 W shall be made with anuncertainty of less than or equal to 2% at the 95% confidence level.

125
126

2) Power measurements with a value less than 0.5 W shall be made with an uncertainty of less thanor equal to 0.01 W at the 95% confidence level.

127
128
129
130
131
132
133

3) All ambient light values (measured lux) shall be measured at the location of the ABC sensor on
the UUT with light entering directly into the sensor and with the main menu from the test signal
from IEC 62087 Ed. 3.0, “Methods of measurement for the power consumption of audio, video
and related equipment” displayed on the product. For products not compatible with the IEC test
signal format, ambient light values shall be measured with the Video Electronics Standard
Association (VESA) Flat Panel Display Measurements Standard version 2.0 (FPDM2) FK test
signal being displayed on the product.

1344) Ambient light values shall be measured within the following tolerances:

135a) At 10 lux, ambient lighting shall be within ± 1.0 lux; and136b) At 300 lux, ambient lighting shall be within ± 9.0 lux.

enabled as-shipped:

225
226
227
228

a) A person shall be within close proximity of the occupancy sensor for the entire warm up,stabilization, luminance testing and On Mode to prevent the UUT from entering a lower powerstate (e.g. Sleep Mode or Off Mode). The UUT shall remain in On Mode for the duration of
the warm up period, stabilization period, luminance test and On Mode test.

229
230
231
232

b) No person shall be within close proximity of the occupancy sensor for the duration of the
Sleep Mode and Off Mode tests to prevent the UUT from entering a higher power state (e.g.

244
245
246

E) Battery Operated Products:
1) For products designed to operate using batteries when not connected to the mains, the battery
shall be removed for all tests. For UUTs where operation without a battery pack is not a
supported configuration, the batteries shall be fully charged before the start of testing and shall beleft in place for the test. To ensure the battery is fully charged, perform the following steps:

247
248

a) For products that have an indicator to show that the battery is fully charged, continue
charging for an additional 5 hours after the charged indicator is present.

249
250
251

b) If there is no charge indicator, but the manufacturer’s instructions provide a time estimate forwhen charging this battery or this capacity of battery should be complete, continue charging
for an additional 5 hours after the manufacturer’s estimate.

252
253
254

c) If there is no indicator and no time estimate in the instructions, but the charging current isstated on the UUT or in the instructions, terminate charging 1 hour after the calculated test
duration or, if none of the above applies, the duration shall be 24 hours.

255
256
257
258

F) Accuracy of Input Signal Levels: When using analog interfaces, video inputs shall be within ± 2% ofreferenced white and black levels. When using digital interfaces, the source video signal shall not be
adjusted for color, or modified by the tester for any purpose other than to compress/inflate andencode/decode for transmission, as required.

7) Adjust appropriate luminance controls until the luminance of the white area of the screen is set as
described in Section 6.3A).

3548) Record the screen luminance (LOn).

355
356
357

9) Record On Mode power (PON) and total pixel format (horizontal x vertical). The On Mode power
shall be measured over a 10 minute period similar to the IEC 62087 Ed 3.0 dynamic broadcastcontent test.

358

6.4 On Mode Testing for Products with ABC Enabled by Default

359
360
361
362

The average On Mode power consumption of the product shall be determined with the dynamic
broadcast-content as defined in IEC 62087 Ed. 3.0. If the product cannot display the IEC signal, then the
VESA FPDM2 L80 test pattern, as described in Section 6.3C)5), shall be used for all of the following
steps.

363
364A) Stabilize the UUT for 30 minutes. This shall be done with three repetitions of the 10 minute IEC
dynamic broadcast-content video signal.

365
366

B) Set the light output of the lamp used for testing to 10 lux as measured at the face of the ambient lightsensor.

367
368C) Display the 10 minute dynamic broadcast-content video signal. Measure and record the power
consumption, P10, during the 10 minute dynamic broadcast-content video signal.

369D) Repeat steps 6.4B) and 6.4C) for an ambient light level of 300 lux, to measure P300.
