4 A) Product Types:
5 1) Electronic Display (Display'): A commercially-available product with a display screen and
6 associated electronics, often encased in a single housing, that as its primary function displays
7 visual information from (1) a computer, workstation or server via one or more inputs (e.g., VGA,
8 DVI, HDMI, IEEE 1394), (2) a USB flash drive, (3) a memory card, or (4) a wireless Internet
9 connection.
10 B) External Power Supply (EPS): Also referred to as External Power Adapter. A component contained in
11 a separate physical enclosure external to a display, designed to convert line voltage AC input from the
12 mains to lesser DC voltage(s) in order to provide power to the display. An EPS connects to the display
13 via a removable or hard-wired male/female electrical connection, cable, cord or other wiring.
14 C) Operational Modes:
15 1) On Mode: The operational mode of a display that (1) is connected to a power source, (2) has all
16 mechanical (hard) power switches turned on, and (3) is producing an image.
17 2) Sleep Mode: The operational mode of a display that (1) is connected to a power source, (2) has all
18 mechanical (hard) power switches turned on, and (3) is in a reduced-power state after receiving a
19 signal from a connected device (e.g., computer, game console, set-top box) or by cause of an
20 internal function (e.g., sleep timer, occupancy sensor). Sleep Mode is considered a "soft" low-
21 power condition, in that the product may exit Sleep Mode upon receiving a signal from a
22 connected device or by cause of an internal function.
23 3) Off Mode: The operational mode of a display that (1) is connected to a power source, (2) has one
24 or more manual power switches turned off, and (3) is not providing any function. The product may
25 only exit Off Mode by cause of direct user actuation of a manual power switch.
