Division C Allowances and adjustments for the purpose of the EEIlabel calculation

Electronic displays with automatic brightness control (ABC) shall qualify for a 10 % reduction in P_measured if they meet all of the following requirements:

1. (a)

   ABC is enabled in the normal configuration of the electronic display and persists in any other standard dynamic range configuration available to the end user;

2. (b)

   the value of P_measured , in the normal configuration, is measured, with ABC disabled or if ABC cannot be disabled, in an ambient light condition of 100 lux measured at the ABC sensor;

3. (c)

   if applicable, the value of P_measured with ABC disabled shall be equal to or greater than the on mode power measured with ABC enabled in an ambient light condition of 100 lux measured at the ABC sensor;

4. (d)

   with ABC enabled, the measured value of the on mode power must decrease by 20 % or more when the ambient light condition, measured at the ABC sensor, is reduced from 100 lux to 12 lux;

5. (e)

   the ABC control of the display screen luminance meets all of the following characteristics when the ambient light condition measured at the ABC sensor changes:

   • the measured screen luminance at 60 lux is between 65 % and 95 % of the screen luminance measured at 100 lux;

   • the measured screen luminance at 35 lux is between 50 % and 80 % of the screen luminance measured at 100 lux;

   • the measured screen luminance at 12 lux is between 35 % and 70 % of the screen luminance measured at 100 lux.
