# Commission Regulation (EU) 2019/2021 of 1 October 2019 laying down ecodesign requirements for electronic displays pursuant to Directive 2009/125/EC of the European Parliament and of the Council, amending Commission Regulation (EC) No 1275/2008 and repealing Commission Regulation (EC) No 642/2009 (Text with EEA relevance), Division 1: ENERGY EFFICIENCY INDEX LIMITS FOR ON-MODE

Extent: E+W+S+N.I.

The energy efficiency index (EEI) of an electronic display shall be calculated using the following equation:
Where:
A represents the screen area in dm2;
Pmeasured is the measured power in Watts in on mode in the normal configuration, in standard dynamic range (SDR);
corr is a correction factor of 10 for OLED electronic displays that do not apply the ABC allowance in point B (1). This shall apply until 28 February 2023. corr shall be zero in all other cases.
The EEI of an electronic display shall not exceed the maximum EEI (EEImax ) according to the limits in Table 1 from the dates indicated.
Table 1
EEI limits for on-mode
EEImax for electronic displays with resolution up to 2 138 400 pixels (HD)
EEImax for electronic displays with resolution above 2 138 400 pixels (HD) and up to 8 294 400 pixels (UHD-4k)
EEImax for electronic displays with resolution above 8 294 400 pixels (UHD-4k) and for MicroLED displays
