NOTE 
NOTE 1: IMAGE PERSISTENCE 
Please be aware that LCD Technology may experience a phenomena known as Image Persistence. Image Persistence occurs when residual or 
“ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ 
image 
persistence is not permanent, but constant images being displayed for a long period of time should be avoided. 
To alleviate image persistence, turn off the monitor for as long as the previous image was displayed. For example, if an 
image was 
on the monitor for one hour and a residual image remains, the monitor should be turned off for one hour to erase the image. 
As with all personal display devices, PHILIPS recommends displaying moving images and using a moving panel saving at regular intervals 
whenever the screen is idle or turning off the monitor when not in use. 
 
Please set “POWER SAVE”, “PANEL SAVING”, “DATE AND TIME” and “SCHEDULE” functions to further reduce the risk of 
Image persistence.   
For long life use of Public Display  
< Image Sticking of LCD Panel > 
When LCD panel is operated continuously for long hours, a trace of electric charge remains near the electrode inside LCD, and residual or “ghost” 
image 
of previous image may be observed. (Image Persistence) 
Image Persistence is not permanent, but when fixed image is displayed for long period, ionic impurities inside LCD are accumulated along 
the displayed image, and it is observed permanently. (Image Sticking) 
< Recommendations > 
For preventing the fast transition to Image Sticking, and for longer life usage of LCD, following are recommended. 
1.    Static images 
should not be displayed for long period. Always use a short cycle to change to other images. 
2.    In case a fixed image is displayed for a long period , it is advised to activate the pixel shift feature that will periodically move the image in four 
directions
 
3.   
When not in use, please turn off the monitor with your remote control, or use Power Management Function or use the Schedule Function of monitor. 
4.    Reducing 
the environmental temperature will increase the life of your monitor. 
When Protection board (glass, acryl) is installed over the LCD surface, enclosed into the box / wall, or stack the monitor, please utilize the 
temperature sensors inside monitor. 
To reduce the environmental temperature, the monitor should be set Low Brightness or Cooling Fan “ON” by using Screen sever Function. 
5.   
Please use Panel saving Mode of monitor.   NOTE 2: HOW TO SETUP SCHEDULE  
Using 
the “SCHEDULE” function allows you to set up to seven different scheduled time intervals when the LCD Monitor will be activated. 
You can select the time the monitor turns on and turns off, the day of week the monitor is activated, and which input source the monitor will 
use for each scheduled activation period. A check mark in the box next to the number of the schedule indicates that the selected schedule is in 
effect. 
To select which schedule to set, use the up/down arrows to move the number (1 to 7) of the schedule. 
Use the (+) and (-) buttons to move the cursor horizontally within the particular schedule. Use the (       ) and (       ) buttons to increase time 
and select input port. The “SET” button is used to make a selection. 
If 
you create a schedule but do not want to use a power on time, select “--” in the “ON” time slot. 
If 
you do not want to use a power off time select “--” in the OFF time slot. 
If 
there is no input selected (“--” showing in the input spot) the input from the previous schedule will be used. 
The selection of EVERY DAY within a schedule takes priority over other schedules that are set up to operate weekly. When schedules 
are overlapping, scheduled Power ON time has priority over scheduled Power OFF time. 
If 
there are two schedules programmed for the same time, then the highest numbered schedule has priority. When the “SLEEP 
TIMER
” is set, the “SCHEDULE” function is disabled.

Pixel defect policy BDL4251V    
Philips strives to deliver the highest quality prod ucts. We use some of the industrys most advanced m anufacturing processes and 
practice stringent quality control. However, pixel  or sub-pixel defects on the PDP /  TFT panels used i n Plasma-  & LCD- displays 
are sometimes unavoidable. No manufacturer can guar antee that all panels will be free from pixel defects, but Philips guarantees 
that any Plasma- & LCD- displays with an unacceptab le number of defects will be repaired during the warranty period in line with 
your local guarantee conditions.   
This notice explains the different types of pixel d efects and defines the acceptable defect level for  the BDL4251V LCD screen. In 
order  to  qualify  for  repair  under  warranty,  the  num ber  of  pixel  defects  must  exceed  a  certain  level  wh ich  is  given  in  the 
reference  table.  If  the  LCD  screen  is  within  specif ication  a  warranty  exchange  /  claim  back  will  be  re fused.  Additionally,  because 
some types or combinations of pixel defects are mor e noticeable than others, Philips sets even higher quality standards for those. 
  
Pixels and Sub-pixels 
 
  
A pixel, or picture element, is composed of three su b-pixels in the primary colors of red, green and blue. Many pixels together 
form an image. When all sub-pixels of a pixel are l it, 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 + Dot definition  
  
Pixel and sub-pixel defects appear on the screen in  different ways. There are three categories of pixel defects and several 
types of sub-pixel defects within each category.    
 
Dot definition = What is a defective “Dot” ?:  
One or more defective, adjacent sub-pixel are define d as one “dot”. The no. of defective sub-pixels are not relevant to 
define a defective dot. This means that a defective  dot can consist of one, two or three defective sub -pixels which can 
be dark or lit. 
One dot = One Pixel; consists of three sub-pixels of  Red; Green and Blue   
  
Bright Dot    Defects 
 
Bright dot defects appear as pixels or sub-pixels t hat are always lit or on. These are the examples  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 dot)

Dark Dot Defects  
 
Black dot defects appear as pixels or sub-pixels th at are always dark or off. These are the examples  of black dot defects:   
 
                   
 
Proximity of Pixel Defects  
    
Because pixel and sub-pixels defects of the same ty pe that are nearby one another may be more noticeab le, Philips also specifies 
tolerances for the proximity of pixel defects. In t he table below you can find specifications about: 
 
·  Allowed amount of adjacent dark dots = (adjacent dar k dots =1 pair of dark dots) 
· Minimum distance between dark dots 
· Total no. of all defective dots 
 
Pixel Defect Tolerances      
In  order  to  qualify  for  repair  due  to  pixel  defects   during  the  warranty  period,  a  PDP  /  TFT  panel  in  a   Philips  Plasma  /  LCD- 
display must have pixel or sub-pixel defects exceed ing the tolerances listed in the following table.
