Division 6.3 On Mode testing for products without ABC enabled by default

United Kingdom

Original text. Later amendments are not shown.

  1. (A)

    After the Luminance Testing and prior to On Mode power measurement, the luminance of the UUT shall be set according to the following:

    1. (1)

      For Signage Displays, the product shall be tested with luminance set at a value greater than or equal to 65 % of the manufacturer-reported maximum luminance (LMax_Reported). Luminance values shall be measured as per Section 6.2. This luminance value LOn shall be recorded.

    2. (2)

      For all other products, adjust appropriate luminance controls until the luminance of the screen is 200 candelas per square metre (cd/m2). If the UUT cannot achieve this luminance, set the product luminance to the nearest achievable value. Luminance values shall be measured as per Section 6.2. This luminance value LOn shall be reported. Appropriate luminance controls refer to any controls that adjust the brightness of the Display, but do not include contrast settings.

  2. (B)

    For a UUT capable of displaying the IEC signals, On Mode power (PON) shall be measured according to IEC 62087:2011 Section 11.6.1 ‘Measurements using dynamic broadcast-content video signal.’ For a UUT not capable of displaying the IEC signals, On Mode power (PON) shall be measured as follows:

    1. (1)

      Ensure that the UUT has been initialised as per Section 6.1.

    2. (2)

      Display the VESA FPDM2, A112-2F, SET01K test pattern (8 shades of grey from full black (0 volts) to full white (0,7 volts)).

    3. (3)

      Verify that input signal levels conform to VESA Video Signal Standard (VSIS), Version 1.0, Rev. 2.0, December 2002.

    4. (4)

      With the brightness and contrast controls at maximum, verify that the white and near-white grey levels can be distinguished. If necessary, adjust contrast controls until the white and near-white grey levels can be distinguished.

    5. (5)

      Display the VESA FPDM2, A112-2H, L80 test pattern (full white (0,7 volts) box that occupies 80 % of the image).

    6. (6)

      Ensure that the luminance measurement area falls entirely within the white portion of the test pattern.

    7. (7)

      Adjust appropriate luminance controls until the luminance of the white area of the screen is set as described in Section 6.3(A).

    8. (8)

      Record the screen luminance (LOn).

    9. (9)

      Record On Mode power (PON) and total pixel format (horizontal ×vertical). The On Mode power shall be measured over a 10-minute period similar to the IEC 62087:2011 dynamic broadcast-content test.
