Cadenza Document - Energy Star

Key Efficiency Criteria
Qualified models meet all ENERGY STAR requirements as
listed in the Version 5.1 ENERGY STAR Program
Requirements for Displays that are effective as of October
30, 2009, or the Version 6.0 ENERGY STAR Program
Requirements for Displays that are effective as of June 1,
2013.
Version 5.1 Requirements
Version 6.0 Requirements
On Mode Max Power Consumption Requirements (Non-
ABC-Enabled):
Calculation of Maximum On Mode Power Requirements
(PON MAX)
Diagonal Screen
Size, d (inches)
Product Type
Screen
Resolution, r
(megapixels)
PON_MAX (watts)
Where:
r = Screen resolution in
megapixels
A = Viewable screen
area, rounded to the
nearest 0.1 square
inches.
On Mode Max Power Consumption Requirements (Non-ABC-
Enabled):
Calculation of Maximum On Mode Power Requirements (PON
MAX)
On Mode power (PON), as measured per the ENERGY STAR test
method (referenced in Table 6), shall be less than or equal to the
Maximum On Mode Power Requirement (PON_MAX), as calculated
and rounded per Equation 1, below. If the product’s pixel density (DP),
as calculated per Equation 1, is greater than 20,000 pixels/in2, then
the screen resolution used to calculate PON_MAX shall be determined
per Equation 2.
Equation 1: Calculation of Pixel Density
D_P=(r×(10)^6)/A
d < 30.0
r ≤ 1.1
r > 1.1
(6.0 x r) + (0.05 x A) +
3.0
(9.0 x r) + (0.05 x A) +
3.0
Notes: DP is the pixel density of the product rounded to the nearest
integer, in pixels/in2,
r is the screen resolution, in megapixels, and
A is the viewable screen area, in in2.
Equation 2: Calculation of Resolution if Dp > 20,000 pixels/in2
r_1=(20,000×A)/(10)^6
r_2=(D_P-20,000)×A)/(10)^6
30.0 ≤ d ≤ 60.0 Any (0.27 x A) + 8.0
Where:
- r1 and r2 are the screen resolutions, in megapixels, to be used when
calculating PON_MAX,
- DP is the pixel density of the product rounded to the nearest integer,
in pixels/in2, and
- A is the viewable screen area, in in2.
Sleep Mode Requirements
Measured Sleep Mode power (PSLEEP) shall be less than or
equal to the Maximum Sleep Mode Power Requirement
(PSLEEP_MAX) of 2 Watts.
Table 1: Calculation of Maximum On Mode Power Requirements
(PON_MAX)
PON_MAX
where Dp ≤ 20,000
pixels/in2 (in watts)
PON_MAX
where Dp > 20,000
pixels/in2 (in watts)
Off Mode Requirements
Measured Off Mode power (POFF) shall be less than or equal
to the Maximum Off Mode Power Requirement (POFF MAX) of
1 Watt.
Number of Units Required for Testing
Representative Models shall be selected for testing per the
following requirements:
For qualification of an individual product model, a product
configuration equivalent to that which is intended to be
marketed and labeled as ENERGY STAR is considered the
Representative Model;
