Division B Energy Efficiency Index (EEIlabel )

United Kingdom

The Energy Efficiency Index (EEI_label ) of the electronic display shall be calculated using the following equation:

where:

A represents the viewing surface area in dm²;

P_measured is the measured power in on mode in Watts in the normal configuration and set as indicated in Table 2;

corr_l is a correction factor set as indicated in Table 3.

Table 2

Measurement of P_measured

Dynamic Range level	P_measured
Standard Dynamic Range (SDR): Pmeasured_SDR	Power demand in Watts (W) in on mode, measured when displaying standardised test sequences of moving picture from dynamic broadcast content. Where allowances are applicable according to part C of this Annex, they should be deducted from P_measured .
High Dynamic Range (HDR) Pmeasured_HDR	Power demand in Watts (W) in on mode, measured as for Pmeasured_SDR but with the HDR functionality activated by metadata in the standardised HDR test sequences. Where allowances are applicable according to part C of this Annex, they should be deducted from P_measured .
