Definition of Pixel Defects
LCD Monitor Quality and Pixel Policy
The TFT monitor uses high-precision technology, manufactured according to HP
standards, to guarantee trouble-free performance. Nevertheless, the display
may have cosmetic imperfections that appear as small bright or dark spots. This
is common to all LCD displays used in products supplied by all vendors and is not
specific to the HP LCD. These imperfections are caused by one or more
defective pixels or sub-pixels.
1. A pixel consists of one red, one green, and one blue sub-pixel.
2. A defective whole pixel is always turned on (a bright spot on a dark
background), or it is always off (a dark spot on a bright background). The first
is the more visible of the two.3. A defective sub-pixel (dot defect) is less
3. visible than a defective whole pixel
and is small and only visible on a specific background.
The HP display does not have more than:
4. 3 bright dots.
5. 5 dark dots.
6. 5 total bright and dark dots.
7. No more than two adjacent (less than 2.5 mm edge-to-edge)
defective pixels.
To locate defective pixels, the monitor should be viewed under normal operating
conditions, in normal operating mode at a supported resolution and refresh rate,
from a distance of approximately 50 cm (16 in.).
HP expects that, over time, the industry will continue to improve its ability to
produce LCDs with fewer cosmetic imperfections And HP will adjust guidelines
as improvements are made.

General points
Input signal
1.1 During the test and measuring, supply a distortion free AC
mains voltage to the apparatus via an isolated transformer
with low internal resistance.
1.2 All measurements mentioned hereafter are carried out at a
normal mains voltage (90 - 132 VAC for USA version,
195 -264 VAC for EUROPEAN version, or 90 - 264 VAC for
the model with full range power supply, unless otherwise
stated.)
1.3 All voltages are to be measured or applied with respect to
ground, unless otherwise stated. Note: don't use heat-sink
as ground.
1.4 The test has to be done on a complete set including LCD
panel after 30 minutes warm-up at least in a room with
temperature of 25 +/- 5 degree C.
1.5 All values mentioned in these test instruction are only
applicable of a well aligned apparatus, with correct signal.
1.6 The letters symbols (B) and (S) placed behind the test
instruction denotes
(B): carried out 100% inspection at assembly line
(S): carried out test by sampling
1.7 The white balance (color temperature) has to be tested in
subdued lighted room.
1.8 Repetitive power on / off cycle are allowed except it should
be avoided within 6 sec.
2.1 Signal type
2.1.1 Video signal input
Signal source: pattern generator format as attachment.
(Table 1 to 34) Reference generator: QuantumData 802G
The input signals can be applied in two different modes:
1). VESA Analog
The video input consists of red, green, and blue signals.
The video signals are analog levels,where 0V corresponds
to black and 700mV is the maximum signal amplitude.
Input impedance of video pins is 75 ohm +- 1%.
2.1.2 Sync signal input
The capability of sync signal inputs shall include separate
sync, composite sync and sync on green. Input
impedance: 2k2 ohms The signals are defined as follow:
Separate sync TTL level, Positive/Negative
Composite sync TTL level, Positive/Negative
Sync on green H-sync TTL level, Positive/Negative
Signal source: pattern generator format as attachment
(Table 1 to 34) Reference generator: QuantumData 802G
