♦ For this test ,an LMD(Light Measurement Device)is needed with adequate response time

♦♦

to track any visible rate flicker component and with a voltage level output proportional To luminance intensity.

♦

♦ Test Pattern: For dot inversion Driving(Gray levels of foreground dots on the test panel

♦♦

Are G22,G32,and G45)

♦

♦ Test Point :Center point of the display area

Note 8) Definition of Crosstalk (Refer to the VESA STD)

The calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh, as follows:

Lmax -Lmin C

=  x100 %

Lmin

Where Lmax is the larger value of Gbkg or Lsh , and Lmin is the smaller of the two.

♦ To determine background and foreground levels (colours),first set the background to any

gray scale or color level suitable for shadowing determination.(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background .Next display the box levels to determine the proper value for the background level. Look for shadowing in any direction from box E. Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed. This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test.

♦ One point only (the target) will be measured. To determine that point proceed as follows Using the background and foreground gray levels of step1 (Gbkg and Gfg). Turn on each

box at a time. Look for the case with the worst shadowing. The box causing the worst case is the shadowing source, or Bsrc. Use Bsrc and the box opposite from it that lies directly in the shadow path. That is the target box, or Btgt. Note that box Eight be either Bsrc or Btgt, depending on the shadowing conditions, but typically Bsrc and Btgt will be a pair of opposite boxes, A&C or B&D. Btgt will only be displayed for aligning the LMD. It will be turned off for the actual measurement.

♦

♦ The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off.

♦♦

(Btgt is for alignment purpose only) Display the background only at level Gbkg. Display Btgt determined in step 2 above. Using the correct distance, angle, and measurement aperture, align the LMD to the center of the Btgt. Turn off Btgt. With Gbkg set to its proper level, measure the luminance (or color). Next,turn on the source box Bsrc. Again measure at the center point of Btgt (without Btgt present.). In this case the LMD will be measuring the shadowing level, Lsh.

2.7.4 Power Management

2.7.4.1 Meet VESA DPMS proposal

The monitor must comply with the Microsoft On Now specification, with a minimum of three power management states, as defined by the VESA DPMS document. The front panel of the monitor must appropriately display the DPMS state, For example:

DPMS ON : The power LED is Green DPMS OFF : The power LED is Amber

Volt Tolerance

2.7.5 Power Consumption

On mode 48 Wmax Green

Off mode 3 Wmax Amber

DC power off 3 Wmax Dark

Power SW off 1 Wmax Dark

disconnection 3 Wmax

 Power saving states are measured with speakers attached but not worked.  The recovery time from stand by /suspend/off mode to on mode is 3 seconds maximun.

Dark (DC power off) Amber (DC power on)
