Philips Pixel Defect Policy
Philips' Flat Panel Monitors Pixel Defect Policy
Philips strives to deliver the highest quality products. We use
some of the industry's most advanced manufacturing processes
and practice stringent quality control. However, pixel or sub pixel
defects on the TFT LCD panels used in flat panel monitors are
sometimes unavoidable. No manufacturer can guarantee that all
panels will be free from pixel defects, but Philips guarantees that
any monitor with an unacceptable number of defects will be
repaired or replaced under warranty. This notice explains the
different types of pixel defects and defines acceptable defect
levels f or each type. In order to qualify for repair or replacement
under warranty, the number of pixel defects on a TFT LCD panel
must exceed these acceptable levels. For example, no more than
0.0004% of the sub pixels on a 19" XGA monitor may be
defective. Furthermore, Philips sets even higher quality
standards for certain types or combinations of pixel defects that
are more noticeable than others. This policy is valid worldwide.
Pixels and Sub 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. Other combinations of lit and dark sub pixels appear
as single 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 sub pixel defects within each category.
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
pattern. There are the types of bright dot defects:
ʳ
ʳ
One lit red, green or
blue sub pixel
ʳ
Two adjacent lit
sub pixels:
-Red+Blue=
Purple
- Red + Green =
Yellow
- Green + Blue =
Cyan (Light Blue)
Three adjacent lit sub
pixels (one white
pixel)
ʳ
ʳ
A red or blue bright dot must be more than 50
percent brighter than neighboring dots while a
green bright dot is 30 percent brighter than
neighboring dots.
ʳ
Black Dot Def ects 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
displays a light pattern. These are the types of black dot defects:
ʳ
One dark sub pixel ʳ
Two or three adjacent dark sub
pixels
ʳ
Proximity of Pixel Defects
Because pixel and sub pixels defects of the same type that are
near to one another may be more noticeable, Philips also
specifies tolerances for the proximity of pixel defects.
Pixel Defect Tolerances
In order to qualify for repair or replacement due to pixel defects
during the warranty period, a TFT LCD panel in a Philips flat
panel monitor must have pixel or sub pixel defects exceeding the
tolerances listed in the following tables.
BRIGHT DOT DEFECTS ACCEPTABLE
LEVEL
MODEL 190CW9

4.Restart your computer and repeat step 2 and 3 to verify that
your PC is set at 1440x900@60Hz (19").
5.Shut down your computer, disconnect your old monitor and
reconnect your Philips LCD monitor.
6.Turn on your monitor and then turn on your PC.
Q: What are the .inf and .icm files on the CD-ROM? How do I
install the drivers (.inf and .icm)?
A: These are the driver files for your monitor. Follow the
instructions in your user manual to install the drivers. Your
computer may ask you for monitor drivers (.inf and .icm files) or a
driver disk when you first install your monitor. Follow the
instructions to insert the ( companion CD-ROM) included in this
package. Monitor drivers (.inf and .icm files) will be installed
automatically.
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 Windows® Control Panel with the "Display properties".
Q: What if I get lost when I am making monitor adjustments?
A: Simply press the Menu button, the Setup button, then select
'Reset' to recall all of the original factory settings
Q: What is the Auto function?
A: The AUTO adjustment key restores the optimal screen
position, phase and clock settings by pressing of a single
button – without the need to navigate through OSD (On Screen
Display) menus and control keys.
Note: Auto function is available in selected models only.
Q: My Monitor has no power (Power LED does not light up).
What should I do?
A: Make sure the AC power cord is connected between the
monitor and AC outlet, and click a key on keyboard/mouse to
wake up the PC.
Q: Will the LCD monitor accept an interlaced signal under
PC models?
A: No. If an Interlace signal is used, the screen displays both odd
and even horizontal scanning lines at the same time, thus
distorting the picture.
Q: What does the Refresh Rate mean for LCD?
A: Unlike CRT display technology, in which the speed of the
electron beam is swept from the top to the bottom of the screen
determines flicker, an active matrix display uses an active
element (TFT) to control each individual pixel and the refresh
rate is therefore not really applicable to LCD technology.
Q: Will the LCD screen be resistant to scratches?
A: A protective coating is applied to the surface of the LCD, 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 subject to any excessive shocks or scratches.
Q: How should I clean the LCD surface?
A: For normal cleaning, use a clean, soft cloth. For extensive
cleaning, please 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 OSD control as
the following procedures,
1. Press "Menu" to show the OSD (On Screen Display) menu
2. Press "Down Arrow" to select the option "Color" then press
"OK" to enter color setting, there are three settings as below.
a. Color Temperature; The six settings are 5000K, 6500K,
7500K, 8200K, 9300K and 11500K. With settings in the 5000K
range the panel appears ‘warm,' with a red-white color tone,
while a 11500K temperature yields ‘cool, blue-white toning."
b. sRGB; this is a standard setting for ensuring correct exchange
of colors between different device (e.g. digital cameras, monitors,
printers, scanners, etc)
c. User Define; the user can choose his/her preference color
setting by adjusting red, green blue color.
d. Gamma; The five settings are 1.8, 2.0, 2.2, 2.4, and 2.6.
*A measurement of the color of light radiated by an object while it
is being heated. This measurement is expressed in terms of
absolute scale, (degrees Kelvin). Lower Kevin temperatures such
as 2004K are red; higher temperatures such as 9300K are blue.
Neutral temperature is white, at 6504K.
Screen Adjustments
Q: When I install my monitor, how do I get the best
performance from the monitor?
A:For best performance, make sure your display settings are set
at 1440x900@60Hz for 19".
Q: How do LCDs compare to CRTs in terms of radiation?
A: Because LCDs do not use an electron gun, they do not
generate the same amount of radiation at the screen surface.
Compatibility with other Peripherals
Q: Can I connect my LCD monitor to any PC, workstation or
Mac?
A: Yes. All Philips LCD monitors are fully compatible with
standard PCs, Macs and workstations. You may need a cable
adapter to connect the monitor to your Mac system. Please
contact your Philips sales representative for more information.
Q: Are Philips LCD monitors Plug-and-Play?
A: Yes, the monitors are Plug-and-Play compatible with
Windows® 95, 98, 2000, XP and Vista.
Q: What is USB (Universal Serial Bus)?
A: Think of USB as a smart plug for PC peripherals. USB
automatically determines resources (like driver software and bus
bandwidth) required by peripherals. USB makes necessary
resources available without user intervention. There are three
main benefits of USB. USB eliminates "case anxiety," the fear of
removing the computer case to install circuit board cards -- that
often requires adjustment of complicated IRQ settings -- for
add-on peripherals. USB does away with "port gridlock." W ithout
USB, PCs are normally limited to one printer, two Com port

FAQs (Frequently Asked Questionis)
devices (usually a mouse and modem), one Enhanced Parallel
Port add-on (scanner or video camera, for example), and a
joystick. More and more peripherals for multimedia computers
come on the market every day. With USB, up to 127 devices can
run simultaneously on one computer. USB permits "hot plug-in."
No need to shut down, plug in, reboot and run set up to install
peripherals. No need to go through the reverse process to unplug
a device. Bottom line: USB transforms today's "Plug-and-Pray"
into true Plug-and-Play!
Please refer to glossary for more information about USB
Q:WhatisaUSBhub?
A: A USB hub provides additional connections to the Universal
Serial Bus. A hub's upstream port connects a hub to the host,
usually a PC. Multiple downstream ports in a hub allows
connection to another hub or device, such as a USB 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
commonly used to display ASCII characters and images on
digital items such as watches, calculators, portable game
consoles, etc. LCD is the technology used for displays in
notebooks and other small computers. Like light-emitting diode
and gas-plasma technologies, LCD allows displays to be much
thinner than cathode ray tube (CRT) technology. LCD consumes
much less power than LED and gas-displays because it works on
the principle of blocking light rather than emitting it.
Q:WhatdifferentiatespassivematrixLCDsfromactive
matrix LCDs?
A: An LCD 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 less current to control the
luminance of a pixel. For 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
appear to move more smoothly across the screen, for example).
The passive matrix LCD 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 CRT monitor, a gun shoots electrons and general light by
colliding polarized electrons on fluorescent glass. Therefore,
CRT monitors basically operate with an analog RGB signal. A
TFT LCD monitor is a device that displays an input image by
operating a liquid crystal panel. The TFT has a fundamentally
different structure than a CRT: Each cell has an active matrix
structure and independent active elements. A TFT LCD has two
glass panels and the space between them is filled with liquid
crystal. When each cell is connected with electrodes and
impressed with voltage, the molecular structure 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,
since it can be very thin and no flickering occurs because it does
not use the scanning method.
Q: Why is vertical frequency of 60Hz optimal for an LCD
monitor?
A: Unlike a CDT monitor, the TFT LCD panel has a fixed
resolution. For example, an XGA monitor has 1024x3 (R, G, B) x
768 pixels and a higher resolution may not be available without
additional software processing. The panel is designed to optimize
the display for a 65MHz dot clock, one of the standards for XGA
displays. Since 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 using the dual-refraction of a liquid crystal.
Using the property that the projection of inlet light refracts toward
the major axis of the liquid element, it controls the direction of
inlet light and displays it. Since the refraction ratio of inlet light on
liquid crystal 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 where the contrast ration is 10.
Many ways to widen the viewing angle are currently being
developed and the most common approach is to use a wide
viewing angle film, which widens the viewing angle by varying the
refraction ratio. IPS (In Plane Switching) or MVA (Multi Vertical
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 CRT monitor -- and it has
no impact of the ease of viewing. Flickering in an LCD monitor
relates to usually undetectable luminance caused by the
difference between positive and negative voltage. On the other
hand, CRT flickering that can irritate the human eye occurs when
the on/off action of the fluorescent object becomes visible. Since
the reaction speed of liquid crystal in an LCD panel is much
slower, this troublesome form of flickering is not present in an
LCD display.
Q: Why is an LCD monitor virtually low of Electro Magnetic
Interference?
A: Unlike a CRT, an LCD monitor does not have key parts that
generate Electro Magnetic Interference, especially magnetic
fields. Also, since an LCD display utilizes relatively low power, its
power supply is extremely quiet.
Ergonomics, Ecology and Safety
Standards
Q: What is the CE mark?
A: The CE (Conformité Européenne) mark is required to be
displayed on all regulated products offered for sale on the
European market. This 'CE' mark means that a product complies
with the relevant European Directive. A European 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 LCD monitor conform to general safety
standards?
A: Yes. Philips LCD monitors conform to the guidelines of MPR-II
and TCO 99/03 standards for the control of radiation,
electromagnetic waves, energy reduction, electrical safety in the
work environment and recyclability. The specification page
provides detailed data on safety standards.
Q: After I change new PC, I found this information on screen,
how can I do?
A: Because you activate Theft Deterrence function in
SmartControl II. Please contact IT manager or Philips Service
Center.
