4.4Brightness uniformity
GENERAL PRODUCT SPECIFICATION
In 1280x1024/60Hz mode, set contrast at 100% and turn the brightness to get average above 200 nits with white pattern.
The Brightness Variation shall be measured at the 9 center points by HP spec(at 10%, 50%, and 90%) called out in
the Measurement Locations Figure 2 below. If Light Leakage is visible, the Maximum Dark Luminance shall be
measured at all 11 points (9-points plus 4-points at the center of each edge).
If measuring data conflicted with above HP specification, it shall follow panel itself spec for brightness uniformity.
For LPL Panel, it shall follow the formula as below
Apply the pattern as fig 3. It should comply with the following formula:
For CMO Panel
Apply the pattern as fig 4. It should comply with the following formula:
4.5Check Cross talk
Cross talk of one area of the screen by another shall be measured by comparing the brightness (YA)ofa10mm± 1mm
diameter area, with all display pixels set to the 32nd (of 0 to 63) gray level, to the brightness (YB) of that same area when
any adjacent area is driven dark as Fig 6. The luminance ratio shall not exceed 1:2.0

There are three factory preset white color 9300K, 6500K and sRGB.
Apply full white pattern, with brightness in 90 % position and the contrast control at 80 % position. The 1931 CIE
Chromaticity (color triangle) diagram (x,y) coordinate for the screen center should be:

Resultno serious damage on set appearance
Product shall meet the operating, non-operating and pack test requirements of HP's specification for Monitor
Environmental and Reliability Testing (rev 6.0 of Oct. 21, 2002). Drop heights shall be determined by Compaq
specification 109291.
All testing shall be done in each of three mutually perpendicular axes, referenced to the position of the system as
it is in front of the user (i.e., front-to-back, side-to-side, and top-to-bottom).
6.2.3Operating Conditions
The unit should suffer no visible cosmetic damage and should operate with no degradation in display quality during
exposure to the operational conditions.
Sinusoidal Vibration: 0.25 g zero-to-peak, 10 to 500 Hz, 0.25 octave / minute sweep rate. One sweep, 10 to 500 to
10 Hz, along each axis.
Random Vibration: 0.002 G2/Hz, 10 to 500 Hz, nominal 1.0 Grms in each of the three axes. The test duration shall
be sufficient so that the monitor's performance can be completely evaluated.
Half Sine Wave Shock: 30 G peak acceleration for 2 milliseconds duration in each of the three axes. The number of
shock inputs in each direction shall be sufficient so the monitor's performance can be evaluated.
6.2.4 Non-Operating
The unit should suffer minimal visible cosmetic damage or damage that presents a safety hazard, or impairs the setup
and operation of the system after testing.
Sinusoidal Vibration: 0.75 G zero-to-peak, 10 to 500 Hz, 0.5 octave / minute sweep rate. This requires one sweep,
10 to 500 to 10 Hz, along each of the three axes.
Random Vibration: 0.008 G2/Hz, 10 to 500 Hz, nominal 2 GRMS. The test shall be for one hour for each of the three
axes.
Half Sine Wave Shock: 50 G peak, half sine pulse, 2 ms pulse duration. Testing shall consist of one shock in each
direction in each axis, for a total of 6 shock inputs.
Square Wave Shock: 35 G peak acceleration, 180 inches / second velocity change. There shall be one shock in each
direction in each axis, for a total of 6 shock inputs.
6.3Display disturbances from external environment

Notes :
Any bright or dark dots visible using the evaluation method described in section 6.6.4 are to be considered defects.
Unless otherwise specified, optical defects whose length L is greater than four times the width W, that is L > 4W,
shall be considered as linear defects. Defects whose length is less than four times the width (L < 4W) shall be
considered as spot defects. All gray shade testing will be based on Shades 1, 12, and 16 for Black/White/Red/Green
/Blue (from a base of 16 gray shades, where 16 is maximum bright and 1 is minimum bright). A high level dot cannot
be adjacent to any other dot.
10.5Smudges, Streaks and Smears
When viewing the panel oriented so as to maximize reflected light, there shall be no visible smudging, streaking,
smearing or other non-uniformity from contaminants, fingerprints, or defects in any of the visible surfaces.
This is independent of whether the unit is operating or off.
