Qualifying Criteria for Displays

Version 5.1

Download the PDF version of this document.

Products sold in Canada must meet all Canadian regulatory and safety requirements. Eligible equipment is to be qualified by the U.S. EPA.

In order to promote ENERGY STAR qualified Displays in Canada, manufacturers are required to sign a Memorandum of Understanding (MOU) with the US Environmental Protection Agency (EPA). We encourage manufacturers, retailers and distributors to sign a Participant Administrative Arrangement with Natural Resources Canada to take advantage of promotional and communications opportunities provided by the program. More information

Please note that the U.S. EPA has made changes to the ENERGY STAR qualification process, in particular to include mandatory third party testing. You can find more information about those changes on the following web site: http//www.energystar.gov

These criteria are the same as the program requirements published on the U.S. ENERGY STAR web site and are provided as information only. Administered by Natural Resources Canada's Office of Energy Efficiency, the ENERGY STAR program in Canada uses the term Participant to designate companies, organizations and stakeholders who promote the use of the ENERGY STAR mark on products or in promotional and marketing material and activities. This technical specification was modified to include this change. The use of the term Participant is similar in scope to that of Partner, which is used by the EPA ENERGY STAR Program.

Following is the Version 5.1 of the ENERGY STAR qualifying criteria for Displays. A product shall meet all of the identified criteria to earn the ENERGY STAR mark. Also, the EPA and Natural Resources Canada both reserve the right to revise the specification should technological and/or market changes affect its usefulness to consumers or industry or its impact on the environment. A product must meet all of the identified criteria to earn the ENERGY STAR registered trademark.

1) Definitions

Product Types

  • A. Electronic Display (Display)
    A commercially-available product with a display screen and associated electronics, often encased in a single housing, that as its primary function displays visual information from (1) a computer, workstation or server via one or more inputs (e.g., VGA, DVI, HDMI, IEEE 1394), (2) a USB flash drive, (3) a memory card, or (4) a wireless Internet connection.

  • B. External Power Supply (EPS)
    Also referred to as External Power Adapter. A component contained in a separate physical enclosure external to a display, designed to convert line voltage AC input from the mains to lesser DC voltage(s) in order to provide power to the display. An EPS connects to the display via a removable or hard-wired male/female electrical connection, cable, cord or other wiring.

Operational Modes

  • A. On Mode
    The operational mode of a display that (1) is connected to a power source, (2) has all mechanical (hard) power switches turned on, and (3) is producing an image.

  • B. Sleep Mode
    The operational mode of a display that (1) is connected to a power source, (2) has all mechanical (hard) power switches turned on, and (3) is in a reduced-power state after receiving a signal from a connected device (e.g., computer, game console, set-top box) or by cause of an internal function (e.g., sleep timer, occupancy sensor). Sleep Mode is considered a "soft" low-power condition, in that the product may exit Sleep Mode upon receiving a signal from a connected device or by cause of an internal function.

  • C. Off Mode
    The operational mode of a display that (1) is connected to a power source, (2) has one or more manual power switches turned off, and (3) is not providing any function. The product may only exit Off Mode by cause of direct user actuation of a manual power switch.

Luminance
The photometric measure of the luminous intensity per unit area of light travelling in a given direction, expressed in units of candelas per square meter (cd/m2)

Screen Area
The viewable screen area of a product, calculated by multiplying the viewable image width by the viewable image height.

Automatic Brightness Control (ABC)
The self-acting mechanism that controls the brightness of a display as a function of ambient light.

Product Family
A group of product models that are (1) made by the same manufacturer, (2) subject to the same ENERGY STAR qualification criteria, and (3) of a common basic design. Product models within a family differ from each other according to one or more characteristics or features that either (1) have no impact on product performance with regard to ENERGY STAR qualification criteria, or (2) are specified herein as acceptable variations within a product family. For Displays, acceptable variations within a product family include:

1) Color, and

2) Housing.

To qualify for ENERGY STAR, a product model shall meet the ENERGY STAR specification in effect on its date of manufacture. The date of manufacture is specific to each unit and is the date (e.g., month and year) on which a unit is considered to be completely assembled.

6.2 Future Specification Revisions: EPA/NRCan reserves the right to change this specification should technological and/or market changes affect its usefulness to consumers, industry, or the environment. In keeping with current policy, revisions to the specification are arrived at through stakeholder discussions.

7) Considerations for Future Revisions

7.1 Greenhouse Gas Emissions

7.1.1 EPA is interested in working with LCD industry stakeholders through the ENERGY STAR program to reduce the emission of high global warming potential gases associated with LCD production, specifically NF3, SF6, and CF4. EPA recognizes the opportunity to significantly reduce emissions beyond product use-phase, and to engage partners in achieving significant, measurable greenhouse gas and energy reductions from other phases of the product lifecycle.

7.2 Harmonization of Displays

7.2.1 EPA is committed to continuing to develop performance levels for displays and televisions in a similar and convergent manner, as reflected in industry and market trends. Under Tier 2, EPA will explore testing all displays for On Mode power using the IEC 62087 test procedure. Issues such as luminance boundary levels, mode requirements, test conditions, power saving features, and other energy related attributes will be explored with stakeholders during the Tier 2 specification development process.
