Philips Pixel Defect Policy
D
Philips' Flat Panel Monitors Pixel Defect Policy
P hilips s trives to deliver the highes t quality products . W e us e
some of the industry's most advanced manufacturing proces ses
and practice stringent quality control. However, pixel or sub pixel
defects on the T F T LC D panels us ed in flat panel monitors are
sometimes unavoidable. No manufacturer can guarantee that all
panels will be free from pixel defects , but P hilips guarantees that
any monitor with an unacceptable number of defects will be
repaired or replaced under warranty. T his notice explains the
different types of pixel defects and defines acceptable defect
levelsforeachtype.Inordertoqualifyforrepairorreplacement
under warranty, the number of pixel defects on a T F T LC D panel
must exceed these acceptable levels. For example, no more than
0.0004% of the sub pixels on a 19" XGA monitor may be
defe ctive. F urthermore, P hilips s ets even higher quality
standards for certain types or combinations of pixel defects that
are more noticeable than others . T his policy is va lid worldwide.
Pixels and S ub pixels
A pixel, or picture element, is composed of three sub pixels in the
primary colors of red, green and blue. Many pixels together form
an image. When all sub pixels of a pixel are lit, the three colored
sub pixels together appear as a single white pixel. When all are
dark, the three colored sub pixels together appear as a single
black pixel. O ther combinations of lit and dark s ub pixels appear
as s ingle pixels of other colors .
Types of Pixel Defects
Pixel and sub pixel defects appear on the screen in different
ways. There are two categories of pixel defects and several types
of s ub pixel defects within ea ch c ategory.
Bright Dot Defects Bright dot defects appear as pixels or sub
pixels that are always lit or 'on'. That is, a bright dot is a sub-pixel
that stands out on the screen when the monitor displays a dark
pa tte rn. T he re a re the ty pe s of bright dot de fe cts :
One lit red, green or
blue s ub pixel
Two adjacent lit sub
pixels :
-Red+Blue=
Purple
- R ed + G reen =
Y ellow
-Green+Blue=
Cyan (Light Blue)
Three adjacentlit sub
pixels (one white
pixel)
Aredorbluebrightdotmustbemore
than 50 percent brighter than neighboring
dots while a green bright dot is 30 percent
brighter than neighboring dots .
Black Dot Defects Black dot defects appear as pixels or sub
pixels that are always dark or 'off'. That is, a dark dot is a
sub-pixel that stands out on the screen when the monitor
dis plays a light pattern. T hes e are the types of black dot defects
One dark sub pixel Two or three adjacent dark
sub pixels
Proximity of Pixel Defects
B ecaus e pixel a nd s ub pixels defects of the s ame type that a re
near to one another may be more noticeable, P hilips als o
specifies tolerances for the proximity of pixel defects

6. Turn on your monitor and then turn on your P C .
Q:Whatdoes'refreshrate'meaninconnectionwithanLCD
monitor?
A: The refresh rate is of much less relevance for LC D monitors .
LC D monitors dis play a s table, flicker-free image at 60Hz. T here
is no visible difference between 85Hz and 60Hz.
Q: What are the .inf and .icm files on the CD-R OM? How do I
install the drivers (.inf and .icm)?
A:Thesearethedriverfilesforyourmonitor.Followthe
ins tructions in your us er manual to install the drivers . Your
computer may ask you for monitor drivers (.inf and .icm files) or a
driver dis k when you firs t ins tall your monitor. F ollow the
ins tructions to ins ert the ( c ompanion C D-R O M) included in this
pac ka ge. Monitor drivers (. inf and .icm files ) will be ins ta lled
a utoma tic a lly.
Q: How do I adjust the resolution?
A: Your video card/graphic driver and monitor together determine
the available resolutions. You can select the desired resolution
under W indows ® C ontrol P a nel with the "Dis play properties ".
Q: What if I get lost when I am making monitor adjustments?

PC models?
A:No.IfanInterlacesignalisused,thescreendisplaysbothodd
and even horizontal scanning lines at the same time, thus
dis torting the picture.
Q: What does the Refresh R ate mean for LCD?
A: U nlike C R T dis play technology, in which the s peed of the
electron beam is swept from the top to the bottom of the screen
determines flicker, an active matrix dis play us es an active
element (TFT) to control each individual pixel and the refresh rate
is therefore not really applicable to LC D technology.
Q: Will the LCD screen be resistant to scratches?
A: A protective coating is applied to the s urface of the LC D,
which is durable to a certain extent (approximately up to the
hardness of a 2H pencil). In general, it is recommended that the
panel surface is not subjectto any excessive shocks or
scratches.
Q: How should I clean the LCD surface?
A: F or normal cleaning, us e a clean, s oft cloth. F or extens ive
cleaning, pleas e use isopropyl alcohol. Do not use other solvents
such as ethyl alcohol, ethanol, acetone, hexane, etc.
Q: Can I change the color setting of my monitor?
A: Yes, you can change your color setting through OS D control
as the following procedures,
1. P res s "OK " to show the OS D (On S creen Display) menu
2. P res s "Down Arrow" to s elect the option "C olor" then pres s

FAQs (Frequently As ked Questionis)
Q: Are Philips LCD monitors Plug-and-Play?
A: Yes , the monitors are P lug-and-P lay compatible with
Windows® 95, 98, 2000, XP and Vista.
Q: What is USB (Universal Serial Bus)?
A: T hink of U S B as a s mart plug for P C peripherals . US B
automatically determines resources (like driver s oftware and bus
bandwidth) required by peripherals . U S B ma kes neces s ary
res ources available without user intervention. T here are three
main benefits of USB. USB eliminates "case anxiety," the fear of
re moving the compute r c as e to ins tall c irc uit boa rd c ards -- that
often requires adjustment of complicated IR Q settings -- for
add-on periphera ls . U S B does away with "port gridlock. " W ithout
US B , P C s are normally limited to one printer, two C om port
devices (us ually a mous e and modem), one E nhanced P arallel
P ort add-on (s canner or video camera, for example), and a
joystick. More and more peripherals for multimedia computers
c om e on the m a rk et e ve ry da y. W ith U S B , up to 12 7 devic e s c a n
run s imultaneous ly on one computer. US B permits "hot plug-in."
No need to s hut down, plug in, reboot and run s et up to install
peripherals. No need to go through the revers e proces s to unplug
a de vic e . B ottom line: U S B tra ns forms toda y 's "P lug-a nd- P ra y "
into true P lug-and-P lay!
Please refer to glossary for more information about USB.
Q: What is a USB hub ?
A: A US B hub provides additional connections to the Universal
S erial B us . A hub's upstream port connects a hub to the host,
usually a P C . Multiple downstream ports in a hub allows
connection to another hub or device, s uch as a US B keyboard,
camera or printer.
LCD Panel Technology
Q: What is a Liquid Crystal Display?
A: A Liquid Crystal Display (LCD) is an optical device that is
c ommonly us e d to dis pla y A S C I I c ha ra c ters a nd ima ge s on
digital items such as watches, calculators, portable game
consoles,etc.LCDisthetechnologyusedfordisplaysin
notebooks and other s ma ll c omputers . Like light-emitting diode
and ga s -plas ma tec hnologies , L C D a llows dis plays to be muc h
thinner than cathode ray tube (C R T ) technology. LC D cons umes
much less power than LE D and gas-displays because it works on
the principle of blocking light rather than emitting it.
Q: What differentiates passive matrix LCDs from active
matrix LCDs?
A: An LC D is made with either a passive matrix or an active
matrix display grid. An active matrix has a transistor located at
each pixel intersection, requiring les s current to control the
luminance of a pixel. F or this reason, the current in an active
matrix display can be switched on and off more frequently,
improving the screen refresh time (your mouse pointer will
a ppea r to move more s moothly a cros s the s cree n, for exa mple ).
T he pas s ive matrix LC D has a grid of conductors with pixels
located at each intersection in the grid.
Q: What are the advantages of TFT LCD compared with
CRT?
A: In a C R T monitor, a gun s hoots electrons and general light by
colliding pola rize d electrons on fluores cent glas s. T herefore,
CRT monitors basically operate with an analog R GB signal. A
TFT LCD monitor is a device that displays an input image by
operating a liquid crystal panel. The TFT has a fundamentally
diffe re nt s truc ture tha n a C R T : E a c h c e ll ha s a n a c tiv e ma trix
s tructure and independent active elements . A T F T L C D has two
glass panels and the space between them is filled with liquid
crystal. When each cell is connected with electrodes and
impres s ed with voltage, the molecular s tructure of the liquid
crystal is altered and controls the amount of inlet lighting to
display images. A TFT LCD has several advantages over a CRT,
s ince it can be very thin and no flickering occ urs becaus e it does
not us e the scanning method.
Q: Why is vertical frequency of 60Hz optimal for an LCD
monitor?
A : Unlike a C DT monitor, the T F T L C D pa ne l ha s a fixed
resolution. For example, an XGA monitor has 1024x3 (R , G, B) x
768 pixels and a higher res olution ma y not be ava ilable without
additional software processing. The panel is designed to optimize
the display for a 65MHz dot clock, one of the s tandards for XG A
dis plays . S ince the vertical/horizontal frequency for this dot clock
is 60Hz/48kHz, the optimum frequency for this monitor is 60Hz.
Q: What kind of wide-angle technology is available? How
does it work?
A: The TFT LCD panel is an element that controls/displays the
inlet of a backlight us ing the dual-refraction of a liquid crys tal.
Us ing the property tha t the projection of inlet light refracts toward
the major axis of the liquid element, it controls the direction of
inlet light and displays it. S ince the refraction ratio of inlet light on
liquid crys tal varies with the inlet angle of the light, the viewing
angle of a TFT is much narrower than that of a CDT. Usually, the
viewing angle refers to the point whe re the c ontras t ration is 10.
Many ways to widen the viewing angle are currently being
developedandthemostcommonapproachistouseawide
viewing angle film, which widens the viewing angle by varying the
refra c tion ratio. IP S (In P lane S witching) or MVA (Multi Ve rtical
Aligned) is also used to give a wider viewing angle.
Q: Why is there no flicker on an LCD Monitor?
A: Technically speaking, LCDs do flicker, but the cause of the
phenomenon is different from that of a C R T monitor -- and it has
no impact of the ease of viewing. F lickering in an LC D monitor
relates to usually undetectable luminance caus ed by the
difference between pos itive and negative voltage. On the other
hand, C R T flickering that can irritate the human eye occurs when
the on/off action of the fluorescent object becomes visible. S ince
the reaction s peed of liquid crys tal in an LC D panel is much
slower, this troubles ome form of flickering is not present in an
LCD display.
Q: Why is an LCD monitor virtually low of E lectro Magnetic
Interference?
A: Unlike a C R T, an LC D monitor does not have key parts that
generate E lectro Magnetic Interference, es pecially magnetic
fields . Als o, s ince an L C D dis play utilizes relatively low power, its
power supply is extremely quiet.
Ergonomics, Ecology and Safety Standards
Q: What is the CE mark?
A: T he C E (C onformité E uropéenne) mark is required to be
dis played on all regulated products offered for s a le on the
European market. This 'CE' mark means that a product complies
with the relevant E uropean Directive. A E uropean Directive is a
European 'Law' that relates to health, safety, environment and
consumer protection, much the same as the U.S . National
Electrical Code and UL Standards.
Q: Does the L C D monitor c onform to general s afety
standards?
A: Yes . P hilips LC D monitors conform to the guidelines of MP R -II
and TC O 99/03 s tandards for the control of radiation,
electromagnetic waves, energy reduction, electrical safety in the
work environment and recyclability. The specification page
provides detailed data on s afety s ta ndards .
Q: After I change new PC, I found this information on screen,
how can I do?
A: B ecause you activate Theft Deterrence function in
S martC ontrol II. P lease contact IT manager or P hilips S ervice
Center.
