ANNEX C
PART II TO THE AGREEMENT
I. DISPLAY SPECIFICATIONS (Version 7.0)
1. Definitions
(A) |
Product Types: (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 information from (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 intended for one person to view in a desk-based environment. (b) Signage Display: An Electronic Display intended for multiple people to view in non-desk-based environments, such as retail or department stores, restaurants, museums, hotels, outdoor venues, airports, conference rooms or classrooms. For the purposes of this specification, a Display shall be classified as a Signage Display if it meets two or more criteria listed below:
|
(B) |
Operational Modes: (1) On Mode: The mode in which the Display has been activated, and is providing the primary function. (2) Sleep Mode: A low-power mode in which the Display provides one or more non-primary protective functions or continuous functions. Note: Sleep Mode may serve the following functions: facilitate the activation of On Mode via remote switch, Touch Technology, internal sensor, or timer; provide information or status displays including clocks; support sensor-based functions; or maintain a network presence. (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 internal signal, or an external signal. 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. |
(C) |
Visual Characteristics: (1) Ambient Light Conditions: The combination of light illuminances in the environment surrounding a Display, such as a living room or an office. (2) Automatic Brightness Control (ABC): The self-acting mechanism that controls the brightness of a Display as a function of Ambient Light Conditions. Note: ABC functionality must be enabled to control the brightness of a Display. (3) Colour Gamut: Colour gamut area shall be reported as a percentage of the CIE LUV 1976 u′ v′ colour space and calculated as per Section 5.18 Gamut Area of the Information Display Measurements Standard Version 1.03. Note: Any gamut support in non-visible/invisible colour areas is not to be counted. The gamut's size must be expressed as a percentage of area of the visible CIE LUV colour space only. (4) Luminance: The photometric measure of the luminous intensity per unit area of light travelling in a given direction, expressed in candelas per square metre (cd/m2). (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 the user manual. (b) Maximum Measured Luminance: The maximum measured luminance the Display may attain by manually configuring its controls, such as brightness and contrast. (c) As-shipped Luminance: The luminance of the Display at the factory default preset setting the manufacturer selects for normal home or applicable market use. (5) Native Vertical Resolution: The number of physical lines along the vertical axis of the Display within the visible area of the Display. Note: A Display with a screen resolution of 1 920 × 1 080 (horizontal × vertical) would have a Native Vertical Resolution of 1 080. (6) 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. |
(D) |
Additional Functions and Features: (1) Bridge Connection: A physical connection between two hub controllers (i.e. USB, FireWire). 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. (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, is maintained even if some components of the Display are powered down. The Display can elect 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. Note: Full Network Connectivity is not limited to a specific set of protocols. Also referred to as ‘network proxy’ functionality and described in the Ecma-393 standard. (3) Occupancy Sensor: A device used to detect human presence in front of or in the area surrounding a Display. Note: An Occupancy Sensor is typically used to switch a Display between On Mode and Sleep Mode. (4) Touch Technology: Enables the user to interact with a product by touching areas on the Display screen. (5) Plug-in Module: A modular plugin device that provides one or more of the following functions without the explicit purpose of providing general computing function:
Note: Modules providing any other additional input options are not considered Plug-in Modules for the purposes of this specification. |
(E) |
Product Family: A group of product models that: (1) are made by the same manufacturer; (2) share the same Screen Area, Resolution, and Maximum Reported Luminance; and (3) are of a common basic screen design. Models within a Product Family may differ from each other according to one or more characteristics or features. For Displays, acceptable variations within a Product Family include:
|
(F) |
Representative Model: The product configuration that is tested for Energy Star qualification and is intended to be marketed and labelled as ENERGY STAR. |
(G) |
Power Source (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. (2) Standard DC: A method for transmitting DC power defined by a well-known technology standard, enabling plug-and-play interoperability. 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. |

Stabilise the UUT for 30 minutes. This shall be done with three repetitions of the 10-minute IEC dynamic broadcast-content video signal. |
(B) |
Set the light output of the lamp used for testing to 12 lux as measured at the face of the ambient light sensor. |
(C) |
Display the 10 minute dynamic broadcast-content video signal. Measure and record the power consumption, P12, during the 10 minute dynamic broadcast-content video signal. |
(D) |
Repeat steps 6.4(B) and 6.4(C) for an ambient light level of 300 lux, to measure P300. |
(E) |
Disable ABC and measure On Mode power (PON) as per Section 6.3. If ABC cannot be disabled, power measurements shall be conducted as follows:
|
6.5. Sleep Mode testing
(A) |
Sleep Mode power (PSLEEP) shall be measured according to IEC 62301:2011, with the additional guidance in Section 5. |
(B) |
The Sleep Mode test shall be conducted with the UUT connected to the Host Machine in the same manner as in the On Mode test. If possible, Sleep Mode shall be enacted by putting the Host Machine to sleep. For a computer Host Machine, Sleep Mode is defined in the Version 6.1 Energy Star Computers specification. |
(C) |
If the product has a variety of Sleep Modes that may be manually selected, or if the product can enter Sleep Mode via different methods (e.g. remote control or putting the Host Machine to sleep), measurements shall be performed and recorded in all Sleep Modes. If the product automatically transitions through its various Sleep Modes, the measurement time shall be long enough to obtain an average of all Sleep Modes. The measurement shall still meet requirements (e.g. stability, measurement period, etc.) outlined in Section 5.3 of IEC 62301:2011. |
6.6. Off Mode testing
(A) |
For products having Off Mode capability, at the conclusion of the Sleep Mode test, initiate Off Mode via the most easily accessible power switch. |
(B) |
Measure Off Mode power (POFF) according to Section 5.3.1 of the IEC 62301:2011. Document the method of adjustment and sequence of events required to reach Off Mode. |
(C) |
Any input synchronising signal check cycle may be ignored when measuring Off Mode power. |
6.7. Additional testing
(A) |
For products with data/networking capabilities or a bridge connection, in addition to tests performed with data/networking capabilities activated and a bridge connection established (see Section 5.2(C)(1)), Sleep Mode Testing shall be performed with data/networking features deactivated and without any bridge connection established, as per Section 5.2(C)(1)(b) and (c). |
(B) |
The presence of Full Network Connectivity shall be determined by testing the Display for network activity in Sleep Mode according to Section 6.7.5.2 of CEA-2037-A, Determination of Television Set Power Consumption, with the following guidance:
