I. Introduction

    DOE adopted a test procedure for televisions (TVs) on June 29, 
1979, as described in 44 FR 37938. The test procedure, previously 10 
CFR part 430, subpart B, appendix H, was repealed on October 20, 2009, 
due to petitions from the California Energy Commission (CEC) and the 
Consumer Electronics Association (CEA) in light of the June 13, 2009 
transition from analog to digital broadcast transmissions to 
televisions (74 FR 53640). As of June 12, 2009, the ``Digital 
Transition and Public Safety Act of 2005'' required that all 
broadcasting stations must transmit in digital to free up analog 
frequencies for public safety communications. (http://www.fcc.gov/cgb/consumerfacts/digitaltv.html) The CEC petitioned for repeal of the 
regulatory provisions establishing the test procedure and defining 
``television set,'' while the CEA petitioned for DOE's adoption of the 
International Electrochemical Commission's test procedure IEC Standard 
62087-2008, ``Methods of measurement for the power consumption of 
audio, video and related equipment.'' DOE is now taking steps required 
to assure the test procedure and standards are modernized to be able to 
capture the energy consumption of current TVs on the market.
    The Energy Policy and Conservation Act of 1975, as amended (EPCA) 
provides DOE the authority to consider and prescribe new energy 
conservation test procedures for TVs. Title III of EPCA (42 U.S.C. 6291 
et seq.) sets forth a variety of provisions designed to improve energy 
efficiency. Part A of title III (42 U.S.C. 6291-6309) establishes the 
``Energy Conservation Program for Consumer Products Other Than 
Automobiles.'' The consumer products subject to this program (hereafter 
``covered products''), include TVs.

[[Page 54049]]

Under EPCA, the overall program consists essentially of testing, 
labeling, and Federal energy conservation standards.
    Section 323 of EPCA (42 U.S.C. 6293) sets forth generally 
applicable criteria and procedures for DOE's adoption and amendment of 
test procedures. It states, for example, that ``[a]ny test procedures 
prescribed or amended under this section shall be reasonably designed 
to produce test results which measure energy efficiency, energy use, or 
estimated annual operating cost of a covered product during a 
representative average use cycle or period of use, as determined by the 
Secretary [of Energy], and shall not be unduly burdensome to conduct.'' 
(42 U.S.C. 6293(b)(3)) Manufacturers of covered products must use test 
procedures prescribed under EPCA as the basis for establishing and 
certifying to DOE that their products comply with energy conservation 
standards adopted under EPCA. (42 U.S.C. 6295(s))

II. Discussion

    While developing a test procedure for TVs, DOE looked to industry 
for existing test procedures. Among the most widely accepted are IEC 
Standard 62087-2008. \1\ and the Environmental Protection Agency's 
(EPA) ``ENERGY STAR Program Requirements for Televisions, Version 
4.1.\2\ '' DOE has also studied CEA-2037 \3\ and has noted that this 
test procedure relies heavily on both the ENERGY STAR and IEC test 
procedures. These test procedures, along with ``Assessment of Options 
for Improving Energy Efficiency Test Procedures for Displays'' 
(prepared for ENERGY STAR, Natural Resources Canada and NYSERDA by Ecos 
Consulting, March 17, 2010), as well as data and guidance provided from 
international subject matter experts, were the basis for identifying 
the below issues.

---------------------------------------------------------------------------

A. Luminance Level Measurements

1. Luminance Ratio
    Although some display technologies' power consumption does not 
change markedly with changes in screen luminance, there is a strong 
correlation between these factors for most modern display technologies. 
This is evident, for example, in plasma, cathode ray tube (CRT), and 
locally dimmed LED-backlit LCD designs. As a result, it can be useful 
to measure the luminance of televisions during the process of 
determining their performance and power consumption. Among preset 
modes, most TVs have a retail picture mode for use in showrooms, in 
which their screens operate at relatively high luminance levels. TVs 
also typically have a home or default picture mode which is 
significantly dimmer and more suited for home viewing conditions.
    ENERGY STAR v. 4.1 states that luminance should be tested at either 
a preset retail picture mode or the brightest selectable preset picture 
mode, therefore indicating that retail picture mode is analogous to the 
brightest selectable preset picture mode or a mode designed to be 
utilized while the TV is in a retail setting. ENERGY STAR v. 4.1 set 
guidelines specifying the picture mode in which TVs are to be set for 
testing by requiring that TVs either have 1) a forced menu where 
consumers can chose the picture mode in which their TV will operate 
(assuming most consumers will chose home or default picture mode), or 
2) be tested as shipped.
    Allowing for qualification in a home or default picture mode may 
encourage manufacturers to ship their TVs with a default picture mode 
dimmer than desired by most consumers, in order to earn a lower 
measured power value. Once purchased, consumers would likely switch the 
TV out of the dim picture mode to achieve a better picture, making the 
test procedure non-representative of actual energy use. To discourage 
this circumvention, and to ensure that TVs' home or default picture 
modes are not too dim for satisfactory consumer viewing, ENERGY STAR v. 
4.1 requires that home or default picture mode luminance be at least 65 
percent of retail picture mode luminance.
    DOE acknowledges that the test procedure should ensure that screens 
are tested at levels sufficiently bright in home or default picture 
mode for satisfactory consumer utility; however, measuring luminance in 
a repeatable, representative manner has proven to be difficult, as 
discussed below. Therefore, DOE would like feedback from interested 
parties on alternative methods to help ensure that the screen 
brightness in home or default picture mode is not overly dim. 
Specifically, DOE is considering the following broad options 
individually or in combination:
     Measuring the power consumption of televisions at 
prescribed luminance levels;
     Eliminating the luminance measurement and comparing the 
ratio between the power consumed in home or default and retail picture 
modes while displaying a dynamic video signal; and/or
     Measuring the power consumption in various relevant 
picture modes.
    DOE would like to receive interested party feedback on alternative 
methods of ensuring that screen brightness is adequate and 
representative, appropriate luminance levels, and proper percentages 
associated with the duration televisions spend at particular luminance 
levels.
2. Test Pattern and Measurement Method
    When testing luminance, ENERGY STAR v. 4.1 requires that a single 
measurement be taken while the TV displays the 3-bar test pattern. The 
single measurement is taken, perpendicular to the center of the screen 
while displaying three bars of white (100 percent) over a black (0 
percent) background, defined in IEC Standard 60107-1:1997, section 
3.2.1.3. Although this test method is also employed by other regulating 
bodies, it may not be the most appropriate. According to a study done 
by Ecos Consulting, the 3-bar test pattern has an average picture level 
(APL) that is not typical of consumer use. This may disadvantage Plasma 
TVs, and has proven to be unpredictable with LED models. Furthermore, 
the single test point measurement is not appropriate for TVs with local 
dimming.
    Alternative test patterns and test measurement methods may be more 
appropriate for the DOE test procedure. An alternative test pattern 
with an APL more similar to both the IEC broadcast video content and 
typical consumer use could be developed as an alternative testing 
pattern. The test pattern should also be technology neutral to prevent 
discrimination against particular TV technologies. However, DOE is 
aware that the IEC 3-bar test pattern has been adopted by multiple 
rulemaking bodies and trade associations such as EPA, CEA, CEC, and 
Australia. Therefore, DOE welcomes feedback from interested parties on 
using the IEC 3 bar test pattern. DOE also welcomes feedback on any 
alternative test patterns, such as a technology-neutral test pattern, 
that could be used in its test procedure.
    Additionally, DOE is also considering a 9-point measurement over a 
single point measurement, since many televisions exhibit significant 
variations in luminance levels between the center and edges of the 
screen. China's test procedure takes the average of

[[Page 54050]]

measurements made at 9 different points on the screen to account for 
those variations in luminance uniformity. DOE would like to receive 
feedback from interested parties on a 9-point test measurement versus a 
single point test measurement.
3. Measurement Distances and Angles
    Measurement angles and distances are important when taking 
luminance readings. Therefore the ENERGY STAR v. 4.1 test procedure 
requires that the luminance measurement be taken ``perpendicular to the 
center of the display screen.'' ENERGY STAR v. 4.1 further specifies 
that for Light Measuring Devices (LMDs) ``that are not to be operated 
in close proximity to the screen, a 500 millimeter distance is 
recommended.''
    However, consumers watch TVs from various distances and angles. The 
test procedure may account for this by requiring that luminance 
measurements be taken at various angles and distances to most 
accurately account for consumer viewing conditions. Testing at various 
angles and distances might affect varying technologies differently 
depending on the particular test pattern. Alternatively, a contact 
measurement could be used, where the measurement device is placed 
directly on the screen to measure luminance.
    DOE would like to receive feedback regarding the appropriateness of 
measuring luminance at the screen or at other distances and angles. 
Further, what distances and angles are optimal for taking these 
measurements?
4. Preset Picture Modes
    As mentioned in section 1 above, ENERGY STAR v. 4.1 and IEC 
Standard 62087 require that TVs be tested in home or default picture 
mode. Many TVs are now equipped with remotes enabling consumers to 
switch easily between picture modes, allowing consumers to, either 
accidentally or intentionally, switch between modes. Easy switching 
between modes may put TVs into a higher power consumption state more 
easily. Currently, neither the ENERGY STAR v. 4.1 nor the IEC Standard 
62087 test procedures account for energy consumption in non-retail or 
non-home modes. If consumers are more likely to switch out of home or 
default picture modes, the energy consumption associated with these 
other modes may require additional testing. Since current test 
procedures only require testing in home or default picture mode, DOE 
would like to receive feedback from interested parties on whether other 
preset viewing modes need to be tested and how to account for preset 
viewing modes.

B. Automatic Brightness Control

1. Room Illuminance
    Automatic brightness control (ABC) is a power savings function that 
enables TVs to adjust screen luminance automatically according to the 
room illuminance. IEC Standard 62087 measures power savings related to 
ABC by requiring that the test be performed in a room with the 
illuminance at a level of 300 lux or greater. ENERGY STAR v. 4.1 
requires the identical measurement at a level of 300 lux or greater 
along with an additional measurement at 0 lux.
    Both IEC Standard 62087 and ENERGY STAR v. 4.1 require that a 
measurement be taken ``at 300 lux or greater'' which is ambiguous, as 
it requires testing at any illuminance greater than 300 lux rather than 
at a discrete point, and may not promote consistent testing across all 
products. Further, the ENERGY STAR v. 4.1 requirement may encourage 
manufacturers to drastically dim TVs at 0 lux (because power 
consumption is tested at 0 lux) and increase screen luminance sharply 
at values slightly over 0 lux to provide a bright picture setting, and 
then flatten out, or be non-responsive to illuminance changes until 
values of 300 lux or greater are achieved (since power consumption is 
tested at levels of 300 lux or greater). As a result, it is difficult 
to predict how much energy ABC will save when televisions are operated 
across a range of representative illuminance conditions.
    A more repeatable and representative method of measuring ABC could 
result from requiring testing at specific illuminance conditions, 
rather than 0 lux and 300 lux or greater, that are more typical of 
consumer viewing conditions. DOE would like to receive comments from 
interested parties on testing at multiple illuminance levels as well as 
which levels would be most appropriate. Possible illuminance levels 
could include 0, 10, 100, and 200 lux.
2. Measurement Location and Lighting
    When measuring ABC, both ENERGY STAR v. 4.1 and IEC Standard 62087 
require that the measurement of room illuminance be taken at the 
location of the light presence sensor. However, there is no indication 
given regarding the orientation of illuminance meter, which can have a 
significant effect on the measured value. Likewise, no guidance is 
provided on the type of light source to be used, and how directional 
that source is, which could affect a light sensor's response.
    DOE is aware that there are alternative locations to measure 
ambient light conditions. For example, rather than measuring 
illuminance at the light presence sensor, the measurement can be taken 
at the center of the screen. This approach may be preferred since the 
consumer views the TV at the center of the screen, ensuring that the 
test procedure is representative of consumer use. DOE welcomes 
interested party feedback on the positioning of illuminance 
measurements.
    Finally, the lighting conditions used when measuring ABC should be 
created in a similar fashion, to promote consistent testing across 
products. DOE welcomes comments on the appropriate method to create 
desired illuminance to measure energy savings associated with ABC.

C. Signal Source

    A number of different devices such as a Blu-ray player, DVD player, 
computer, or signal generator can serve as the signal source, which can 
be transmitted via high-definition multimedia interface (HDMI), digital 
component, or video graphics array (VGA) cables.
    The IEC Standard 62087 test procedure requires an RF input signal 
or baseband input signal if RF is not available. The ENERGY STAR v. 4.1 
requires that the input signals must be within 2% of 
reference black and white levels. If the device has HDMI, this shall be 
used. Although both methods are sound, in order to obtain the most 
accurate and consistent power and luminance measurements, a standard 
method should be used.
    DOE is considering which signal source is most robust to ensure 
repeatable and reproducible test procedure results. In a study done by 
Ecos, the use of a standard input generator with a HDMI input was found 
to produce the least varied results. Ecos concluded that if a signal 
generator was not used, a DVD or Blu-ray player would also be 
sufficient for conducting luminance ratio measurements; however, a 
personal computer did not provide a sufficiently consistent signal. 
Ecos also determined that when HDMI is not available, a component 
connection should be utilized. DOE would like interested parties to 
comment on the best possible signal sources and connections for use in 
its test procedure.

D. Steady State

    TVs should reach steady state prior to the technician measuring 
both power and luminance. The warm-up periods

[[Page 54051]]

for power measurements specified in IEC Standard 62087 and ENERGY STAR 
v. 4.1 are dependent on the video signal being used to test the TV. For 
static video signals, the measurement must be taken before the 
activation of image retention prevention features. Whereas for 
broadcast-content video and internet-content video signals, the 
measurement is taken after the TV has been operating for 1 hour. The 
lengthy warm-up requirement may not be necessary for all TV 
technologies, requiring unnecessary burden on manufacturers; therefore 
DOE would like to solicit comments from interested parties on 
appropriate warm-up periods or a method of ensuring that the variation 
in the measured power is within a particular percentage needed for TVs 
to reach steady-state.
    For conducting luminance measurements, the ENERGY STAR v. 4.1 test 
procedure requires the luminance test pattern to run for 10 minutes 
before recording a measurement, noting that if the TV stabilizes prior 
to 10 minutes, a measurement can be taken earlier. DOE believes that 
the 10 minute warm-up period may not provide sufficient time to allow 
all TV technologies to stabilize. However, a longer warm-up period will 
increase the overall time needed to conduct a full test. DOE would like 
to receive comments from interested parties on the time required for TV 
luminance to stabilize.

E. Three Dimensional Technology

    Both the IEC and ENERGY STAR v. 4.1 test procedures only account 
for testing of two dimensional (2D) images. However, three dimensional 
(3D) technology in TVs is becoming increasingly popular and DOE is 
unaware of any existing test methods for accurately measuring energy 
use for 3D technology using 3D images. Although 3D TVs can switch to 2D 
viewing and be tested using existing 2D test procedures, the 2D test 
patterns and testing methods might not account for the potential 
increase in energy use associated with 3D picture settings. DOE 
requests feedback from interested parties on testing 3D TVs.

F. Download Acquisition Mode

    The ENERGY STAR v. 4.1 test procedure defines download acquisition 
mode as:

    ``Where the product is connected to a mains power source, is not 
producing a sound or a picture, and is actively downloading channel 
listing information according to a defined schedule for use by the 
electronic programming guide, monitoring for emergency messaging/
communications and/or otherwise communicating through a network 
protocol. The power use in this mode is typically greater than the 
power requirement in Sleep and less than that in On Mode.''

    While IEC Standard 62087 does account for energy consumed in 
download acquisition mode, the ENERGY STAR v. 4.1 test procedure 
requires that download acquisition mode be tested according to the test 
procedure developed by ROVI Corporation (http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/television/Procedure_DAM_Testing.pdf). DOE is considering if and how it should measure 
download acquisition mode and would like interested party feedback on 
the issue.

G. Internet Connectivity

    TVs are increasingly designed to include the ability to connect to 
the internet. This technology allows users to stream information 
directly from the internet for display onto their TV, potentially 
causing TVs to consume more energy. IEC Standard 62087 measures 
internet usage by requiring that a power measurement be taken while the 
television is displaying an internet content video signal. Although 
internet and television images may differ, DOE would like to receive 
comment on the energy required to connect to and display images from 
the internet.

H. Power Saving Technologies

1. Presence Sensors
    Presence sensors use a technology that enables a TV to sense the 
presence of viewers through movement and body heat. The TV will power 
down if it senses a lack of a viewer in the room, in order to save 
energy. IEC Standard 62087 measures savings related to other power 
saving functions but does not specify a detailed test method for 
testing presence sensor technology.
    To ensure that all power saving technologies are accounted for 
correctly in the test procedure, DOE is considering whether or not to 
develop a more detailed test procedure to test savings associated with 
the presence sensor technology. DOE would like to receive comment on 
this issue.
2. Other Power Saving Technologies
    DOE is aware that many power saving technologies exist for TVs. For 
example, Video Electronics Standards Association (VESA) Display Power 
Management System (DPMS), which manages the power supply of computer 
displays, and HDMI Consumer Electronics Control (CEC), which allows 
users to manage their entertainment system to reduce energy use. IEC 
Standard 62087 accounts for other power saving functions by simply 
requiring that the user ``test other power saving functions,'' but does 
not specify particular testing methods for these technologies.
    In order to ensure the most repeatable and reproducible testing 
method, DOE would like to receive comment on possible methods to test 
these as well as other viable power saving technologies.

I. Scope of Coverage

    Traditionally, computer monitors and televisions have been tested 
separately since each requires different technologies and were utilized 
differently by consumers. Recently, however, televisions have begun to 
integrate the internet and other computer-like features. Similarly, 
some computer monitors now feature television viewing capabilities. 
Both the technologies and markets for computer monitors and television 
have begun to merge, with some identical products being marketed 
separately as televisions and monitors. For instance, LCD panels are 
often identical in similar-sized monitors and TVs; new TVs often come 
equipped to receive VGA input; and monitors often come equipped with 
HDMI inputs. DOE would like feedback on whether to include computer 
monitors in the scope of the television test procedure to account for 
the current amalgamation of the traditionally different products.
    ENERGY STAR v. 4.1's scope includes televisions with computer 
capability but distinguishes between televisions and computer monitors 
only based on how they are marketed and sold to consumers. DOE would 
like to receive comment on whether computer monitor and television 
technology require separate testing methods or could be tested using 
the same methods.
    DOE seeks responses from interested parties and requests submission 
of comments, relevant data, and information related to the issues 
described above.

III. Public Participation

    DOE is also interested in comments on other relevant issues that 
participants believe would affect test procedures applicable to this 
product. DOE invites all interested parties to submit in writing by 
October 4, 2010, comments and information on matters addressed in this 
notice and on other matters relevant to DOE's consideration of new test 
procedures for TVs.
    After the close of the comment period, DOE will begin collecting 
data, conducting the analyses, and reviewing

[[Page 54052]]

the public comments. These actions will be taken to aid in the 
development of a test procedure NOPR for TVs.
    DOE considers public participation to be a very important part of 
the process for developing test procedures. DOE actively encourages the 
participation and interaction of the public during the comment period 
in each stage of the rulemaking process. Interactions with and between 
members of the public provide a balanced discussion of the issues and 
assist DOE in the rulemaking process. Anyone who wishes to be added to 
the DOE mailing list to receive future notices and information about 
this rulemaking should contact Ms. Brenda Edwards at (202) 586-2945, or 
via e-mail at [email protected].
