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 for 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.
Ty pes 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:
One lit red, green or
blue sub pixel
Two adjacent lit sub
pixels:
- Red + Blue =
Purple
- Red + Green =
Yellow
- Green + Blue =
Cyan (Light Blue)
Three adjacent lit sub
pixels (one white
pixel)
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.
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 displays a light pattern. These are the types of
black dot defects:
One dark sub pixel Two or three adjacent dark sub pixels
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

FAQs (Frequently Asked Questions)
General FAQs
Q: When I install my monitor what should I do if the screen show s
'Cannot display this video mode'?
A: Recommended video mode for Philips 19": 1440x900 @60Hz.
1. Unplug all cables, then connect your PC to the monitor that you
used previously.
2. In the Windows Start Menu, select Settings/Control Panel. In
the Control Panel Window, select the Display icon. Inside the
Display Control Panel, select the 'Settings' tab. Under the
setting tab, in box labeled 'desktop area', move the slidebar to
1440x900 pixels (19").
3. Open 'Advanced Properties' and set the Refresh Rate to 60Hz,
then click OK.
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 Kelvin 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 comp atible 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." Without USB,
PCs are normally limited to one printer, two Com port 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: What is a USB hub ?
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.

FAQs (Frequently Asked Questions)
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: What differentiates passive matrix LCDs from active 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 CRT 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 CRT.
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 TCO Displays
5.0 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.

DDC Data Re-programming
In case the DDC data memory IC or main EEPROM which storage all factory settings were
replaced due to a defect, the serial numbers have to be re-programmed "Analog
DDC IC, Digital DDC IC & EEPROM".
It is advised to re-soldered DDC IC and main EEPROM from the old board onto the new
board if circuit board have been replaced, in this case the DDC data does not need to be
re-programmed.
