|
---|---|
A < 190
|
(4.00×r)+(0.172×A)+ 1.50 |
190 ≤ A <210
|
(4.00×r)+(0.020×A)+30.40 |
210 ≤ A <315
|
(4.00×r)+(0.091×A)+15.40 |
A ≥ 315
|
(4.00 x r) + (0.182 x A) – 13.20 |
r is the screen resolution in megapixels
|
|
A is the Screen Area in in2

Total Energy Consumption Requirement (kWh)
|
---|
E_TEC≤(E_(TEC_MAX)+E_EP+E_ABC+E_N+E_T+E_C+E_HDR+E_USB) ×eff_(AC_DC) |
E_EP is the enhanced performance display allowance |
E_ABC is the Automatic Brightness Control allowance |
E_N is the Full Network Connectivity allowance |
E_T is the Touch Functionality allowance |
E_C is the curved Display allowance |
E_HDR is the HDR Display allowance |
E_USB is the allowance for Displays with USB-C Power Deliver functionality |
eff_(AC_DC) is the standard adjustment for ac-dc power conversion losses that occur at the device powering the Display, and is 1.0 for Ac-powered Displays and 0.85 for Displays with Standard dc |
Total Energy Consumption Allowances (kWh)

SIGNAGE DISPLAYS
Maximum On Mode Calculation (W)
|
---|
P_ON_MAX = (4.0×10^(-5) x ℓ ×A)+120×tanh(0.0005×(A-140.0)+0.03)+20 |
A = Screen Area in square inches |
ℓ = Maximum Measured Luminance of the display in candelas per square meter |
On Mode Requirement (W)
|
---|
P_ON ≤ P_ON_MAX+P_ABC+P_Module
|
P_ABC is the Measured On Mode Power allowance for ABC in watts |
P_Module is the Measured On Mode Power allowance for embedded modules in watts |

Maximum Sleep Mode Power Requirement (W)
|
---|
0.5
|
Sleep Mode Requirement (W)
|
---|
P_SLEEP ≤ P_SLEEP_MAX + P_N+ P_OS+P_T |
P_N is the Full Network Connectivity allowance |
P_OS is the Occupancy Sensor allowance |
P_T is the Touch allowance for Signage Displays with screen size over 30 inches |
