WARNING
Take care during handling the LCD module with backlight
unit
- Must mount the module using mounting holes arranged in four
corners.
- Do not press on the panel, edge of the frame strongly or electric
shock as this will result in damage to the screen.
- Do not scratch or press on the panel with any sharp objects, such
as pencil or pen as this may result in damage to the panel.
- Protect the module from the ESD as it may damage the electronic
circuit (C -MOS).
-
Make certain that treatment body are grounded through
wrist band.
- Do not leave the
module in high temperature and
in areas of high
humidity for a long time.
- Avoid contact with water as it may as hort circuit within the module.
-
If the surface of panel become dirty
, please wi
pe it of f with a soft
material. (Cleaning with a dirty or rough cloth may damage the
panel.)

Description of the On Screen Display
ʳ
What is the On-Screen Display?
ʳ
On-Screen Display (OSD) is a feature in all Philips LCD monitors. It allows an end user to adjust screen performance or
select functions of the monitors directly through an on-screen instruction window. A user friendly on screen display
interface is shown as below :
ʳ
ʳ
Basic and simple instruction on the control keys.
ʳ
In the OSD shown above users can press buttons at the front bezel of the monitor to move the cursor, to
confirm the choice or change.

Philips Pixel Defect Policy
ʳ
Philips' Flat Panel Monitors Pixel Defect Policy
ʳ
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.
ʳTypes of Pixel Defects
ʳ
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. ʳ
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
ʳ
One lit red, green or
blue sub pixelʳ
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 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:ʳ
ʳ
One dark sub pixelʳ Two or three adjacent dark sub pixelsʳ
Proximity of Pixel Defects
ʳ
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
ʳ
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.ʳ

3. Timing requirement
3.1 Factory Preset mode definition:
3.1.1 Perfect FOS while presenting those timings.
3.1.2 Will specify those timing in User's Manual
3.2 Preset mode definition:
3.2.1 Need to support those timings.
3.2.2 Perfect FOS after auto adjustment.
3.3 User mode
3.3.1 Can save those timing that not in Preset mode and can be showed
(not over scalar or Panel spec.)
3.3.2 It needs to reserve the 10 timings space in memory size.
3.3.3 Factory modes and preset modes are defined in the enclosed timing table file

DDC Instructions
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.
Additional information
Additional information about DDC (Display Data Channel) may be obtained from Video
Electronics Standards Association (VESA).
Extended Display Identification Data(EDID) information may be also obtained from
VESA.
Configuration and procedure
"PI-EDID" The software is provided by IMS to upgrade the firmware of CPU.
PI-EDID Tools is for the interface between "Parallel Port of PC" and "15 pin-D-SUB
connector of Monitor".
It is a windows-based program, which cannot be run in MS-DOS.
System and equipment requirements
1. An Pentium (or above) personal computer or compatible.
2. Microsoft operation system Windows 95/98/2000/XP and Port95NT.exe.
3. EDID Software "PI-EDID.exe"
4. ISP boardas shown in Fig. 1
