Description of the On Screen Display

What is the On-Screen Display?

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 :

Basic and simple instruction on the control keys.

In the OSD shown above users can press buttons at the front bezel of the monitor to move the cursor, to

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.

ʳTypes 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. 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

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

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.ʳ

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"
