10
11

1) Electronic Display (Display): A product with a display screen and associated electronics,
often encased in a single housing, that as its primary function produces visual informationfrom (1) a computer, workstation, or server via one or more inputs (e.g., VGA, DVI, HDMI,
DisplayPort, IEEE 1394, USB), (2) external storage (e.g., USB flash drive, memory card), or(3) a network connection.
a) Monitor: An Electronic Display with pixel density greater than 5,000 pixels per square2
inch (pixels/in ).

12
13

Note: Monitors are typically intended for one person to view in a desk based
environment.

1415b) Signage Display: An Electronic Display with pixel density less than or equal to 5,000
2pixels per square inch (pixels/in ).

16
17
18

Note: Signage Displays are typically intended for multiple people to view in non-deskbased environments, such as retail or department stores, restaurants, museums,
hotels, outdoor venues, airports, conference rooms or classrooms.

19
20
21

Note: EPA seeks feedback as to whether Digital Picture Frames are still sold today and if so, whether
energy saving opportunities exist. There are no Digital Picture Frames currently certified to the ENERGYSTAR Version 6.0 specification.

22
23

EPA is also proposing revised definitions for Monitors and Signage Displays to better demarcate theseproduct types as follows:

24

Product Type
Monitor

may not necessarily
personapply to all products

Signage Display≤5,000 pixels/in2
non-desk-based
environment to beviewed primarily bymultiple people

25
26
27

EPA seeks feedback on the appropriateness of continuing to specify pixel density for these products andwhether EPA has characterized the products’ intended viewing environments correctly.

31

EPA is proposing to maintain separate criteria for enhanced performance displays, acknowledging thatsuch displays have added features that require additional energy. Therefore, EPA proposes to accountfor enhanced performance displays with an allowance in the On Mode Power Requirements section
rather than characterizing them as a separate product category in the Definitions section.

32B) Operational Modes:

3334

1) On Mode: The mode in which the Display has been activated, and is providing the primaryfunction.

35362) Sleep Mode: A low-power mode in which the Display provides one or more non-primary
protective functions or continuous functions.

37
38
39

Note: Sleep Mode may facilitate the activation of On Mode via remote switch, internal sensor, or
timer; provide information or status displays including clocks; support sensor-based functions; ormaintain a network presence.

40
41
42

3) Off Mode: The mode where the Display is connected to a power source, produces no visual
information, and cannot be switched into any other mode with the remote control unit, an internalsignal, or an external signal.

43
44

Note: The Display may only exit this mode by direct user actuation of an integrated power switch
or control. Some products may not have an Off Mode.

45
46
47

Note: EPA is proposing slightly revised definitions above for On Mode, Sleep Mode, and Off Mode toclarify the types of functions and include notes where helpful. EPA welcomes stakeholder feedback as towhether these modes appropriately capture the operation of Displays.

48
49
50

C) Visual Characteristics:
1) Luminance: The photometric measure of the luminous intensity per unit area of light2
travelling in a given direction, expressed in candelas per square meter (cd/m ).

51
52
53

a) Maximum Reported Luminance: The maximum Luminance the Display may attain at
an On Mode preset setting, and as specified by the manufacturer, for example, in theuser manual.

5455b) Maximum Measured Luminance: The maximum measured Luminance the Display
may attain by manually configuring its controls, such as brightness and contrast.

5657c) As-shipped Luminance: The Luminance of the Display at the factory default preset
setting the manufacturer selects for normal home or applicable market use.

58
59
60
61
62
63
64

2) Screen Area: The visible area of the Display that produces images.
Note: Screen Area is calculated by multiplying the viewable image width by the viewable
image height. For curved screens, measure the width and height along the arc of the
Display.
Note: EPA is proposing a minor clarification to the definition of Screen Area noting that it is the visiblearea of the Display and defining how it is calculated. EPA has also included a guidance and clarification
for measuring the Area of a curved screen.

65663) Automatic Brightness Control (ABC): The self-acting mechanism that controls the brightnessof a Display as a function of Ambient Light Conditions.

67684) Ambient Light Conditions: The combination of light illuminances in the environment
surrounding a display, such as a living room or an office.

69705) Native Vertical Resolution: The number of visible physical lines along the vertical axis of the
Display.

71
72

Note: A Display with a screen resolution of 1920 x 1080 (horizontal x vertical) would have a
Native Vertical Resolution of 1080).

73
74
75
76
77

Note: EPA is proposing to include a definition for Native Vertical Resolution consistent with the Draft 2
Version 7.0 Televisions specification which specifies that the count should be of the number of visiblelines on the screen and not of those that might be obscured behind a bezel or other components. EPA
welcomes stakeholder feedback on this definition as it applies to Displays.
D) Additional Functions and Features:

781) Bridge Connection: A physical connection between two hub controllers (i.e., USB, FireWire).

7980

Note: Bridge Connections allow for expansion of ports typically for the purpose of relocating
the ports to a more convenient location or increasing the number of available ports.

81
82

Note: EPA has separated the commentary for the definition of Bridge Connection into a note for greater
clarity.

83
84
85
86
87
88

2) Full Network Connectivity: The ability of the Display to maintain network presence while in
Sleep Mode. Presence of the Display, its network services, and its applications, ismaintained even if some components of the Display are powered down. The Display canelect to change power states based on receipt of network data from remote network devices,
but should otherwise stay in Sleep Mode absent a demand for services from a remote
network device.

89
90

Note: Full Network Connectivity is not limited to a specific set of protocols. Also referred toas “network proxy” functionality and described in the Ecma-393 standard.

91
92
93
94
95
96
97
98

Note: EPA is proposing to replace the definition of Network Capability with Full Network Connectivity
harmonizing with the Draft 2 Version 7.0 Televisions Specification, the Version 6.0 Computers
Specification, and the Version 3.0 Telephony Specification. The definition is accompanied by a proposed
test procedure in the Draft 2 ENERGY STAR Displays Test Method Section 6.7. The test confirms thatthe display can maintain and respond to a network presence over Internet Protocol in order to receive theproposed Sleep Mode power allowance. EPA welcomes feedback on the above definition and whether it
accurately captures the network functions that may be present in displays on the market today or indevelopment.

991003) Occupancy Sensor: A device used to detect human presence in front of or in the areasurrounding a display.

101
102
103
104

Note: An Occupancy Sensor is typically used to switch a Display between On Mode andSleep Mode.
4) Touch Technology: Enables the user to interact with a product by touching areas on ascreen or other surface.

105
106
107

Note: EPA has added a proposed definition for Touch Technology to better describe how this function is
being integrated in Displays. EPA seeks feedback on this proposed definition and the prevalence ofTouch Technology in products.

108
109

EPA encourages stakeholder feedback on the prevalence, capability (multi or single point touch), andpower use of the following Touch Technologies in Monitors and Signage Displays.

- Resistive- Capacitive- Optical and Infrared- Dispersive Signal- Surface Acoustic Wave
EPA would also like to understand whether Touch Technology is typically enabled by default for Sleep
and On Mode. What processing capability or connections (i.e., USB to host) are necessary for Touch
Technology to operate? What accessories are required?
5) Internal Processor: An internal device that provides one or more of the specific functions
without the explicit purpose of providing general computing function:

121
122

a) Display images, mirror remote content streamed to it or otherwise render content on
the screen from local or remote sources; or123b) Process touch signals.

124
125
126
127

Note: EPA has added a proposed definition for Internal Processor to acknowledge capabilities that might
be present in Signage Displays or Monitors for either rendering images or processing touch signals. Thisdefinition is intended to exclude any processing capability that might meet the threshold of a computer for
general computing use for ENERGY STAR purposes

128
129

EPA requests stakeholder feedback on this definition and the presence of Internal Processors in Signage
Displays as follows:

130
131
132
133

- Are Internal Processors shipped with the Display in its default condition?
- Are Internal Processors typically modular?
- What is the typical range of processing capability?
- Can touch screens and other functions operate without a modular processor installed?

134
135
136
137
138
139

E) Product Family: A group of product models that are (1) made by the same manufacturer, (2)share the same Screen Area, Resolution, and Maximum Reported Luminance, and (3) of acommon basic screen design. Models within a Product Family may differ from each otheraccording to one or more characteristics or features. For Displays, acceptable variations within a
Product Family include:

140

1) Color,

1412) Housing;1423) Number and types of interfaces;

1434) Number and types of data, network, or peripheral ports; and144

5) Processing and memory capability.

145
146
147
148
149

Note: EPA proposes clarifications to the definition of Product Family to be more specific about the typesof acceptable variations. In particular, EPA anticipates that under this definition the models within a
Product Family would share similar screen technology but could vary in other characteristics that do nothave a large impact on the primary function of displays such as available ports, sensors, and processing
and memory capability.

150
151

F) Representative Model: The product configuration that is tested for ENERGY STAR certificationand is intended to be marketed and labeled as ENERGY STAR.

152

G) Power Source

ENERGY STAR Program Requirements for Displays – Draft Eligibility Criteria

Page 4 of 15

153
154
155

1) External Power Supply (EPS): An external power supply circuit that is used to convert
household electric current into dc current or lower-voltage ac current to operate a consumer
product.

156
157

Note: EPA has updated the definition of External Power Supply to harmonize with the U.S. Department ofEnergy10 Code of Federal Regulations 430.2.

158
159

2) Standard dc: A method for transmitting dc power defined by a well-known technology
standard, enabling plug-and-play interoperability.

160
161
162

Note: Common examples are USB and Power-over-Ethernet. Usually Standard dc includes
both power and communications over the same cable, but as with the
380 V dc standard, that is not required.

163
164

Note: EPA is proposing a definition for Standard dc power and welcomes stakeholder feedback on its
applicability.

165

2 SCOPE

166

2.1

Included Products

167
168
169
170

2.1.1

Products that meet the definition of a Display as specified herein and are powered directly fromac mains or Standard dc are eligible for ENERGY STAR certification, with the exception of
products listed in Section 2.2. Typical products that would be eligible for certification under thisspecification include:

171

i.

Monitors;

172

ii.

Monitors with keyboard, video, and mouse (KVM) switch functionality;

173

iii.

Signage Displays; and

174

iv.

Signage Displays and Monitors with Internal Processors.

175
176
177
178
179
180

Note: EPA has modified the Included Products language to explicitly mention dc-powered products.
Display products that are primarily intended to be dc-powered are expected to become more prevalent on
the market with the recent updates to USB and Power-over-Ethernet. In February 2014, the Departmentof Energy (DOE) released its first draft of the test method for dc-powered products and is releasing thesecond draft with this Draft 1 specification. Subsequent sections of this specification propose how thepower requirements should be applied to dc-powered products.

181
182
183
184

EPA has specified with a definition of Internal Processor that Signage Displays and Monitors that haveminimal processing for image or touch rendering are included in the scope of this specification rather thanthe ENERGY STAR Computers specification. EPA requests stakeholder comment on any further
clarification needed to delineate Displays from Computers.

185

2.2

Excluded Products

186
187
188
189

2.2.1

Products that are covered under other ENERGY STAR product specifications are not eligible forcertification under this specification including Televisions and Computers (Thin Clients,
Slates/Tablets). The list of specifications currently in effect can be found atwww.energystar.gov/products.

192
193
194

Note: EPA has included specific examples of products covered under ENERGY STAR specifications thatare excluded from this specification. In particular, please refer to the ENERGY STAR Version 6.0/6.1
Computers Specification for definitions of Thin Clients and Slates/Tablets. EPA welcomes stakeholder
feedback on whether or not these exclusions are unclear or if there is any overlap between the producttypes.

195

2.2.2

The following products are not eligible for certification under this specification:

196

i.

Products with an integrated television tuner;

197
198
199

ii.

Displays designed to operate primarily with integrated or replaceable batteries without the
support of ac mains or external dc power (e.g., electronic readers, battery-powered digital
picture frames); and

200
201
202

iii.

Products that must meet Food and Drug Administration specifications for medical devices
that prohibit power management capabilities and/or do not have a power state meeting thedefinition of Sleep Mode.

203
204
205
206
207
208

Note: EPA proposes removing the exclusion for products with a viewable diagonal screen size greaterthan 61 inches. Some Signage Displays sold today are larger than 61 inches. EPA seeks to differentiate
for consumers top performing products and therefore proposes to include these larger sizes in the scopeof this specification. EPA also proposes excluding products designed to operate with integrated or
replaceable batteries which includes many digital picture frames. EPA welcomes stakeholder commenton excluding these types of products.

209
210

For simplicity, EPA has further removed the following exclusion language because the exclusion of
television tuners covers the types of products described in exclusions formerly numbered i and ii, below.

211
212

i.
Products that are marketed and sold as televisions, including products with a computer input port
(e.g., VGA) that are marketed and sold primarily as televisions;

213
214
215
216

ii.
Products that are component televisions. A component television is a product that is composed of
two or more separate components (e.g., display device and tuner) that are marketed and sold as atelevision under a single model or system designation. A component television may have more than one
power cord217

Note: Monitors: Since the introduction of Version 6.0 in fall 2012, the number of ENERGY STAR certified
models of Monitors has grown to represent the majority of the total available models on the market.
Market share has grown to approximately 80–90 percent in 2014. This represents an opportunity for the
ENERGY STAR program to further differentiate among the highly efficient Monitors on the market,
helping to ensure that the ENERGY STAR label remains an effective tool for consumers. With this Draft 1,
EPA used as its dataset 962 unique models, and is proposing power requirements that capture, on
average, the top 20 percent of available Monitors in the market today. The proposed criteria would
recognize a good selection of models across all common sizes from 15 major Monitor manufacturers.
Recognizing similarities among Monitors and televisions, EPA proposes an approach to capture the top
performing Monitors that allows for products of all sizes to meet the requirements but where larger, moreconsumptive units must meet more stringent requirements As seen with televisions, as products haveincreased in size while maintaining resolution, they have also demonstrated the ability to achieve
proportionally greater power consumption reductions and maintain product performance. As
manufacturers continue to offer Monitors in larger sizes today than ones offered in the past, EPA seeks toreward and further incentivize improvements in efficiency among larger sizes.

267
268
269
270
271
272

EPA continues to propose an allowance based on resolution, as a higher resolution, all other things being
equal, has typically demonstrated a need for additional energy. ENERGY STAR certified Monitor datashows that today’s Monitors can deliver higher resolution with a lower power budget than they previously
required, such that a smaller coefficient for watts/megapixel is appropriate. Therefore, based on an
analysis of resolution and power consumption within EPA’s dataset, EPA proposes providing a 2.0 watts
per megapixel allowance, rather than the 6.0 watts per megapixel allotted under the current specification.

Note: Signage: EPA‘s proposal captures the top performing Signage Display products in the market
today that are less than or equal to 60 inches in diagonal screen size and that all have as-shipped screen
2luminances that are typically 500-700 cd/m or less. EPA used as its dataset products currently certified
to the ENERGY STAR. In researching the market, it appears that certified models represent the majorityof market for products within the scope of the current specification, namely products less than or equal to
60 inches in screen size, which all appear to be intended primarily for indoor uses, based on their asshipped screen luminances. EPA understands that the market for Signage includes products larger than
60 inches in diagonal screen size, products with TVs tuners which therefore qualify under the Televisions
specification, and niche products that may be sold in separate components for customizable installation.
EPA is interested in expanding the scope to capture more Signage Displays of interest to buyers. To thisend, under the Version 7.0 Displays specification, EPA proposes expanding the scope to include products
greater than 60 inches in screen size and anticipates that the number of certified products will increase
once these larger screen sizes become eligible for inclusion.

297

As with its proposed approach for Monitors, EPA proposes an approach to capture the top performing
Signage Displays such that larger screens must deliver performance with a similar power budget as
smaller displays. As screens grow in size, EPA seeks to recognize products that have optimized
efficiencies and therefore limit increased energy consumption. Such an approach builds on the energy
savings demonstrated by TV products. In recent years TVs in very large sizes have demonstrated theability to achieve proportionally greater power consumption reductions and maintain product performanceas size has increased, notwithstanding increases in resolution. With this proposal, EPA seeks to reward
and further incentivize the development of such products among Signage, given technological similarities
between TVs and Signage Displays. EPA seeks data from manufacturers, using the Displays Test
Method, for Signage Displays greater than 60 inches and seeks feedback from all stakeholders on its
approach.

In addition, EPA proposes its On Mode Power limit for Signage Displays based on As-Shipped
Luminance, as well as Area, after finding a wide range of as-shipped luminances among Signage
Displays. Signage Displays of the same size may have different as-shipped luminances—some brighter,some less bright—depending on their intended use (i.e., indoor vs. outdoor), which also impacts thepower consumption of the product. Within the EPA dataset containing a variety of manufacturers’
products, the proposed criteria capture the top-performing Signage Displays evenly across sizes ranging
2
from 30 inches to 60 inches and as-shipped luminance ranging from 50 to 800 cd/m . Under EPA’s
proposed approach, products would be granted a scalable allowance based on the screen totalluminance in megacandelas. EPA seeks feedback on this proposed approach that accounts for productswith significant variations in as-shipped luminances. EPA is considering a cap for the luminanceallowance to incentivize gains in efficiency and to set an overall limit in total energy consumption for2
Signage Displays that ship at significantly higher screen luminances (i.e., >2000 cd/m ). In addition, EPA
seeks to determine how to best account for variations in any other physical characteristics and intended
uses for Signage. Specifically, EPA requests the following information from stakeholders:

3121) What physical variations exist among Signage Displays and for what intended uses?

313
314

2) What types of products have screen luminances typically over 500 cd/m and what is theircorresponding power consumption, using the ENERGY STAR Displays Test Method?

315
316
317

3.3.2

For all Displays, Measured On Mode Power (PON) in watts shall be less than or equal the
calculation of Maximum On Mode Power (PON_MAX) with the applicable allowances andadjustments per Equation 1.

Equation 1: On Mode Power Requirement for All Displays

Where:









𝑃𝑂𝑂 ≤ (𝑃𝑂𝑂_𝑀𝑀𝑀 + 𝑃𝐸𝐸 + 𝑃𝐴𝐴𝐴 ) × 𝑒𝑒𝑒𝐴𝐴_𝐷𝐷_𝑂𝑂

PON is Measured On Mode Power in watts;
PON_MAX is the Maximum On Mode Power in watts;
PEP is the On Mode Power allowance in watts for an enhanced performance display;
PABC is the On Mode power allowance for ABC in watt; andeffAC_DC_ON is the standard adjustment for ac-dc power conversion losses that occur at the device
powering the Display in On Mode, and is 1.0 for Ac-powered Displays and 0.85 for displays tested
with Standard dc.
The result shall be rounded to the nearest tenth of a watt for reporting.

329
330
331

Note: EPA has added the above equation to better depict how the power requirements, allowances, andadjustments are applied. To avoid confusion, PON in the specification is always the actual Measured On
Mode Power as tested per the ENERGY STAR test method.

332
333
334
335
336

For dc-powered Displays, EPA is proposing to factor in the losses due to the computer power supply anddc-dc conversions in the connected computer to permit a fair comparison with ac-powered Displays (EPA
assumes most dc-powered displays will be used with computers). EPA determined the 85% conversion
efficiency factor for Displays with Standard dc by reviewing data submitted under the ENERGY STAR
Computers specification.

337
338
339
340
341
342
343

EPA calculated the typical power supply loads when the Display would be in On Mode (equivalent to
Short Idle in the Computers specification) as approximately 30% of rated output power. EPA thenreviewed efficiency data at the 20% and 50% loading points (for internal power supplies) and the averageat the 25%, 50%, 75%, and 100% loading points (for external power supplies). The conversion
efficiencies based on this analysis suggests displays with Standard dc will see conversion efficiencies
ranging from 85% to 91% in On Mode. EPA chose an efficiency factor at the low end of this range to beconservative. EPA welcomes stakeholder comment on these assumptions.

345

For Displays meeting the following enhanced performance criteria, a power allowance (PEP), as
calculated per Equation 2, shall be added to PON_MAX, as calculated per Equation 1:

3.3.3

346
347

i.

A contrast ratio of at least 60:1 measured at a horizontal viewing angle of at least 85°, withor without a screen cover glass;

348

ii.

A native resolution greater than or equal to 2.3 megapixels (MP); and,

349
350

iii.

A color gamut size of at least sRGB as defined by IEC 61966-2-1. Alternate color spaces
are allowable as long as 99% or more of defined sRGB colors are supported.

351
352

Note: Only the 2-dimensional gamut of x and y coordinates for red, green, and blue areneeded to form an eligible color space on the CIE 1931 xy chromaticity diagram.

353
354
355

Note: In response to questions about the Version 6.0 requirement, EPA has included the above noteclarifying the color space that shall be considered. EPA welcomes feedback on this clarification andwhether the characteristics outlined above reflect today’s enhanced performance displays.

356

Equation 2: Calculation of On Mode Power Allowance for Enhanced Performance Displays

357
358
359
360

Where:



𝑃𝐸𝐸 = 0.30 × 𝑃𝑂𝑂_𝑀𝑀𝑀

PEP is the On Mode power allowance in watts for an enhanced performance Display;
PON_MAX is the Maximum On Mode Power requirement in watts; and

362
363
364
365
366
367
368
369
370
371

Note: Since the Version 6.0 went into effect in 2013, EPA has seen a rise in the amount of Enhanced
Performance Displays (EPDs) available on the market. As a result, EPA seeks to differentiate for endusers more efficient EPD models. Under the Version 7.0 specification, EPA is proposing to revise therequirements for enhanced performance displays such that single allowance of 30 percent is applied to
EPDs of all sizes. In contrast, under Version 6.0, EPDs less than 27 inches receive a 30 percent
allowance and EPDs greater than or equal to 27 inches receive a 75 percent allowance. Under the
proposed EPD allowance combined with the proposed On Mode levels, 14 out of the 38 ENERGY STAR
Version 6.0 certified EPDs across of a variety of sizes would continue to qualify for the ENERGY STAR.
EPA welcomes stakeholder feedback to confirm that the existing 38 enhanced performance ENERGYSTAR certified Displays represent most EPDs currently on the market and, if not, EPA seeks additional
data for any EPDs not already be certified.

For Monitors with ABC enabled by default, a power allowance (PABC), as calculated per Equation
4, shall be added to PON_MAX, as calculated per Equation 1, if the On Mode power reduction(RABC), as calculated per Equation 3, is greater than or equal to 20%.

Where:


𝑃300 − 𝑃12

Note: To determine if ABC is enabled by default and can therefore qualify for an allowance, EPA
proposes calculating power consumption at 12 lux in lieu of the current 10 lux. Doing so harmonizes withthe lux values required for testing TVs with ABC enabled by default in the Televisions specification—
given similarities between how Displays and TVs are tested for the ENERGY STAR—and does notprovide a significant change since 10 lux and 12 lux reflect similar room brightnesses. EPA seeks
feedback on this approach and whether the 300 and 12 lux values accurately represent an averagecross-section of lighting conditions in offices, given that a large majority of Monitors sold today are for
office environments. A limited, dated body of research on office lighting conditions prescribes ambient
light conditions closer to 400-500 lux, though EPA understands that lighting conditions could have
evolved since then to include dimmer settings.

A review of ENERGY STAR-certified product data shows that Monitors shipping with ABC enabled bydefault can deliver ABC functionality with a much lower allowance. Therefore, for Monitors, EPA proposes
reducing the ABC allowance from 10 percent to 5 percent. Of products currently qualified with ABC
enabled by default, 40 percent would continue to qualify with a reduced adder of 5 percent and 30
percent would continue to qualify with no adder provided.

In order to determine if the proposed ABC allowances are applicable to Signage Displays or if different
criteria need to be developed, EPA seeks feedback on which lux levels accurately represent a variety oflighting conditions where Signage Displays are typically used, in both indoor and outdoor commercial
environments. EPA seeks feedback on the current implementation of, or the feasibility of implementing,additional power management features, such as Automatic Brightness Control, sensors, and Auto Power
Down, where the product automatically enters a lower power mode after a prescribed period of time, that
could lead to significant energy savings. For example, in the case of Signage Displays that need to bebrightly lit for long periods of time (e.g., in public transportation settings) EPA seeks feedback on whichpower management features could apply. Finally, DOE and EPA also seek feedback on the extent towhich very bright environments could be replicated for testing purposes indoors.

7.1.1

On Mode DC Power Limit: EPA is in interested in considering a separate On Mode Power
Maximum requirement for Standard dc products that does not necessitate an ac-dc conversion
calculation. EPA anticipates these products will become more popular on the market with thelatest USB standard and looks forward to receiving additional direct dc-tested data for theseproducts.
