Philips Pixel Defect Policy
Philips' Flat Panel Monitors Pixel Defect Policy
Philips strives to deliver the highest quality products. W e
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 15" 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.
190S8
LCD

Black Dot Defects Black dot defects appear as pixels or sub
pixels that are always dark or 'off'. These are the types of black
dot defects:
One dark sub pixel
T wo 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 T FT LCD panel in a P hilips flat panel
monitor must have pixel or sub pixel defects exceeding the
tolerances listed in the following tables.
BRIGHT DOT DEFECTS

MODEL
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 s ingle
white pixel. When all are dark, the three colored sub pixels
together appear as a s ingle black pixel. Other combinations
of lit and dark sub pixels appear as single pixels of other
colors.

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
three types of bright dot defects:
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.

A: Make s ure the AC power cord is connec ted between the monitor and AC outlet, and click a key on key board/mous e to wak e up the P C .
Q: Will the L C D monitor acc ept an interlac ed s ignal under P C models?
A: No. If an Interlac e s ignal is us ed, the s cree n dis play s both odd and even horizontal s canning lines at the s ame time, thus dis torting the picture.
Q: What does the R efres h R ate mean for L C D?
A: Unlike C R T dis play technology, in which the s peed of the electron beam is s wept from the top to the bottom of the s cree n determines flicker, an
ac tive matrix dis play us es an active element (T F T ) to control eac h individual pixel and the refres h rate is therefore not really applicable to LC D
technology.
Q: Will the L C D s creen be resist ant to scr atch es ?
A: A protective coa ting is applied to the s urfac e of the LC D, which is durable to a certain ex tent (approximately up to the hardnes s of a 2H pencil). In
general, it is recommended that the panel s urface is not subject to any exce ssi ve sho cks or scr atches .

C ompatibility with other P eripherals
Q: Ar e P hilips L C D monitors P lug-and-P lay?
A: Ye s, the monitors are P lug-and-Pla y compatible with Windows 95, 98, 200 0 and XP.
Q: Wh at is US B (Un ivers al S er ial B us )?
A: T hink of US B as a s mart plug for P C periphera ls. USB automatically determines resou rces (like driver software and bus bandwidth) required by peripherals .
US B mak es necess ary res ources avai lable without use r intervention. T here are three main benefits of US B. US B eliminates "cas e anx iety," the fear of
removing the computer cas e to ins tall circuit board cards -- that often requires adjustment of complicated IR Q s ettings -- for add-on peripherals . US B d oes
away with "port gridlock." Without USB, PC s are normally limited to one printer, two C om port devices (us ually a mous e and modem), one E nhanced P aralle l
Por t add-on (sc anner or video came ra, for example ), and a joystick. More and more peripheral s for multimedia computers come on the market every day.
With USB, up to 127 devices ca n run simultane ous ly on one computer. US B permits "hot plug-in." No nee d to s hut down, plug in, reboot and run se t up to
install peripherals . No need to go through the revers e proce ss to unplug a device. B ottom line: USB transforms today's "Pl ug-and-P ray" into true
Plug -and-Pl ay! P leas e refer to glos sar y for more information about US B .
Q: Wh at is a USB hub ?
A: A US B hub provides additional connections to the Univers al S erial B us . A hub's upstrea m port connects a hub to the host, us ually a P C. Multiple
downs tream ports in a hub allows connection to another hub or device, su ch as a USB keyboard, camer a or printer.
LC D P anel T ec hnology
Q: What is a L iquid C rysta l Disp lay?
A: A Liquid C rysta l Display (LC D) is an optical device that is commonly us ed to display AS C II charac ters and images on digital items such as watches,
calculators, portable game cons oles , etc. LCD is the technology use d for dis plays in notebooks and other s mall computers. Like light-emitting diode and
gas -plasm a tec hnologies , LC D allows displa ys to be much thinner than cathode ray tube( C R T ) technology.LC D consumes much les s power than LED and
gas -displays bec ause it works on the principle of blocking light rather than emitting it.
Q: What differentiates pas s ive matrix LC Ds from ac tive matrix LC Ds ?
A: An LC D is made with either a pas s ive matrix or an active matrix dis play grid. An ac tive matrix has a transistor located at eac h pixel interse ction, requiring
les s current to control the luminance of a pixel. F or this rea so n, the current in an ac tive matrix display can be switched on and off more frequently, improving
the scre en refres h time (your mous e pointer will appear to move more smoothly ac ross the screen , for example). T he pas s ive matrix LC D has a grid of
conductors with pixels loca ted at each intersec tion in the grid.
Q: Wh at are the ad van tag es of T F T L C D c ompar ed with C R T ?
A: In a CRT monitor, a gun sho ots electrons and general light by colliding polarized electrons on fluoresce nt glass. Th erefo re, C RT monitors basically operate
with an analog R G B s ignal. A T F T LC D monitor is a device that dis plays an input image by operating a liquid crystal panel. T he T F T has a fundamen tally
different structure than a C R T : E ach cell has an active matrix structure and independent active elements. A T F T LC D has two glas s panels and the spa ce
between them is filled with liquid crystal . When each cell is connected with electrodes and impres sed with voltage, the molec ular structure of the liquid
crys tal is altered and controls the amount of inlet lighting to display images . A TFT LCD has s everal advantages over a CRT, s ince it can be very thin and no
flickering occurs beca us e it does not us e the scanning method.
Q: Why is vertic al frequenc y of 60Hz optimal for an L C D monitor?
A: Unlike a C DT monitor, the T F T LC D panel has a fixed res olution. F or exam ple, an X G A monitor has 1024x3 (R , G , B ) x 768 pixels and a higher reso lution
may not be available without additional so ftware proce ssi ng. T he panel is desi gned to optimize the display for a 65MH z dot clock, one of the s tandards for
X G A display s. Sinc e the
Q: What kind of wide-angle tec hnology is available? How does it work?
A: T he T F T LC D panel is an eleme nt that controls/displays the inlet of a backlight us ing the dual-refrac tion of a liquid crystal. Using the property that the
projec tion of inlet light refrac ts toward the major axis of the liquid elemen t, it controls the direction of inlet light and dis plays it. Si nce the refraction ratio of
inlet light on liquid crystal varies with the inlet angle of the light, the viewing angle of a T F T is much narrower than that of a C DT . Us ually, 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 approac h is to
use a wide viewing angle film, which widens the viewing angle by varying the refraction ratio. IP S (In Pl ane S witching) or MVA (Multi Ve rtical Aligned) is
also us ed to give a wider viewing angle.
Q: Why is there no flic ker on an LC D Monitor?
A: T ech nically speaki ng, LC Ds 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 eas e of
viewing. F lickering in an LC D monitor rela tes to us ually undetec table luminance ca us ed by the difference between positive and nega tive voltage . On
the other hand, C R T flickering that can irritate the human eye occurs when the on/off action of the fluores cent objec t bec omes visible. Si nce the rea ction
spe ed of liquid crys tal in an LC D panel is much slower, this troublesom e form of flickering is not pres ent in an LC D display.
Q: Why is an LC D monitor virtually low of E lec tro Magnetic Interferenc e?
A: Unlike a C R T , an LC D monitor does not have key parts that generate El ec tro Magnetic Interferenc e, es pecially magnetic fields. Also , since an LC D
display utilizes relatively low power, its power s upply is extremely quiet.
E rgonomic s , E c ology and S afety S tandards
Q: Wh at is the C E mark?
A: T he C E (C onformite E uropeenne) mark is required to be displayed on all regulated products offered for sale on the Eu ropea n market. T his 'C E' mark
mean s that a product complies with the releva nt Eu ropean Directive. A E uropea n Direc tive is a E uropean 'La w' that rela tes to health, s afety, environment
and cons umer protection, much the same as the U.S . National Ele ctrical C ode and UL S tandards.

component (see Fiq. 2B).
- Oxidation on the terminals of SMDs results in poor soldering.
Do not handle SMDs with bare hands.
- Avoid using storage places that are sensitive to oxidation
such as places with sulphur or chlorine gas, direct sunlight,
high temperatures or a high degree of humidity. The
capacitance or resistance value of the SMDs may be
affected by this.
- Rough handling of circuit boards containing SMDs may
cause damage to the components as well as the circuit

You can identify lead-free product by Philips-lead-free logo on PCB.
4. Lead-free product repair instruction
4.1 Use only lead-free Solder Alloy 0622 149 00106(1.2mm SAC305) or 0622 14900108(1.0mm SAC305).
Remark: For lead free soldering material, please visit www.alphametals.com website for details. This is recommended by Philips.
4.2 Use only adequate solder tools applicable for lead-free soldering-tin. The solder tool must be able to reach at least a
solder-temperature of 400 , to stabilize the adjusted temperature at the solder-tip and to exchange solder-tips for different applications.

4.6 Special information for lead-free BGA-ICs: this ICs will be delivered in so-called dry-packaging to protect the IC against moisture and
with lead-free logo on it. This packaging may only be opened shortly before it is used (soldered). Otherwise the body of the IC gets wet
inside and during the heating time the structure of the IC will be destroyed due to high (steam-)pressure. If the packaging was opened
before usage the IC has to be heated up for some hours (around 90 ) for drying (T ake attention for ESD-protection!)
5. Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is
removed from a P WB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, it is essential when removing an (LF)BGA, the board, tracks, solder lands, or
surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature
close to the reflow soldering temperature. A uniform temperature reduces the chance of warping the PWB.
To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board
is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the(LF)BGA
Note: Do not apply solder paste, as this has shown to result in problems during re-soldering.
Device Replacement
The last step in the repair process is to solder the new component on the board. Ideally , the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers.
To reflow the solder , apply a temperature profile according to the IC data sheet. So as not to damage neighbouring
components, it may be necessary to reduce some temperatures and times.
