Philips Pixel Defect Policy
One dark sub pixelTwo or three adjacent dark sub pixels
Proximity of Pixel Defects 
Because pixel and sub pixels defects of the same type that are near to o\
ne 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 durin\
g the warranty period, a TFT 
LCD panel in a Philips flat panel monitor must have pixel or sub pixel d\
efects exceeding the 
tolerances listed in the following tables.
 
BRIGHT DOT DEFECTS ACCEPTABLE LEVEL
MODEL BDL4221V
1 lit sub pixel 0
2 adjacent lit sub pixels 0
3 adjacent lit sub pixels (one white pixel) 0
75% ~ 50% of Dot 0
50% ~ Less Dot (Weak Dot) Max 7
Distance between two bright dot defects* N/A
Total bright dot defects of all types 0

1. Introduction 
1.1 Purpose 
This document describes how to operate the BDS Monitor Series, using the IR remote 
control unit (using standard Philips RC5 code) and the RS-232 Serial Communication 
Interface. This document defines all the command and messages exchanged \
between 
the master and the slave monitors for BDS. It also describes the ways to send or read 
the commands or the messages. 
1.2 Scope 
This document is the reference for design, implementation and testing the RC and 
RS232 communication module for Philips BDS project. 
1.3 Definitions, Abbreviations and Acronyms 
SICP stands for “Serial Interface Communication Protocol”.

2. Enabling The IR Remote Control 
2.1 Monitor Address 
To allow individual control, a 3-digit address (decimal format) is ass\
igned to each 
monitor that can be modified by the user. 
The default address set in the factory is 000. 
2.2 Enabling and disabling the IR remote control(Reserved) 
If the remote controller is disabled by the SICP command in section 3.3.2.9, the remote 
controller doesn’t work since the monitor is powered on. It is possible to enable or 
disable the remote control device on the addressed monitor by sending the following key 
code: 
 
1 XXX Enable remote control on the addressed (XXX) monitor 
0 XXX Disable remote control on the addressed (XXX) monitor 
 
Where  and  stand for the “UP” and “DOWN” cursor buttons on the IR remote 
controller (see also Fig. 1 ]). The input of two consecutive buttons cannot exceed 3 
seconds, or the input sequence will be reset. 
2.3 Changing the monitor address(Reserved) 
It is possible to modify the monitor address by means of the following two commands: 
 
9 NNN Set a new address (NNN), also enabling the remote control 
9 NNN Set a new address (NNN), also disabling the remote control 
 
The input of two consecutive buttons cannot exceed 3 seconds, or the input sequence 
will be reset. 
When using the above commands, please be sure that only the relevant monitor is 
switched on, in order to avoid interference with the other ones. 
2.4 Notice(Reserved) 
If the panel is on stand-by, it wakes up after receiving one of the above commands. If not 
used for more than 30 seconds (that counts since the last button input is received), the 
IR interface is automatically disabled.

3. Serial Interface Communication Protocol 
3.1 General specifications 
3.1.1 Protocol definition  
Communication to the main monitor microprocessor is possible through the\
 serial port, 
which support a communication protocol dedicated to BDS only. The protocol is \
specifically designed to allow data communication in half duplex multi-point 
environments, but it can also be used for half duplex point-to-point RS-232 
communication. 
3.1.2 Communication characteristics 
A half duplex communication is implemented starting from the concept of \
a master-slave 
structure, where the monitor is supposed to be the slave. 
The first action is always taken by the master, which can be either a built-in PC-based 
video controller in a MASTER monitor or any external device (acting a server) interfaced 
to the monitor. After sending a command or a request in the appropriate for\
mat (see 
section 3.2), the master receives form the slave an acknowledgement, wh\
ich tells the 
transmitter whether the command is not valid (or not executable, anyway\
) or it is 
accepted. 
In case of a request, the requested information is sent back and it becomes the 
acknowledgement by itself. 
If the poll sequence has been sent, the acknowledgement tells the transmitter the 
monitor status, i.e. whether it is ready or busy and other information. \
3.1.3 RS232 pin assignment 
There is a 9-pin male connector on the set for RS232 communication. The pin 
assignment is as following table. 
 
Pin No. Function Description 
1 GND Signal Ground 
2 RxD Receive Data 
3 TxD Transmit Data 
4 NC Not Connected 
5 GND Signal Ground 
6 NC Not Connected 
7 NC Not Connected 
8 NC Not Connected 
 
9 NC Not Connected 
 
3.1.4 RS232 settings 
This section describes the parameters used during the whole communicatio\
n process. 
 
Baud rate 57600 bps
Data bits 8 bits
Parity None
Stop bit 1
Flow Control None

3.2 Data frame 
3.2.1 Poll sequence: frame format 
The poll sequence must be transmitted before sending any command, to che\
ck whether 
the monitor is ready to accept a command or it is busy. 
The poll message in enclosed in a frame that has the following format: 
 
    
 
where: 
 
 =  , i.e. ASCII characters [1Bh] and [24h]. 
 
 = 3 ASCII characters each of which ranging from [30h] to [39h], which are 
used as monitor address. 
 
 = the ASCII character [45h]. 
 
 = , i.e. the ASCII character [3Bh]. 
 
3.2.2 Acknowledge to poll sequence: frame format 
 Once the monitor has received the poll sequence, it returns the followin\
g message: 
 
     
 
where: 
 
 =   , i.e. ASCII characters [1Bh] and [25h]. 
 
 = 3 ASCII characters each of which ranging from [30h] to [39h], which are 
used as monitor address. 
 
 = 2 ASCII characters (ranging from [30h] to [39h], i.e. digits  to , 
and from [41h] to [46h]), i.e. letters  to ), representing the most 
significant nibble (bit 7 to bit 4) and the least significant nibble (bit 3 to 
bit 0) of the Status byte, respectively. 
 
  The meaning of the bits in the status byte is as follows: 
 
  Bit [7]: set to 0   (not used, reserved) 
  Bit [6]: set to 0   (not used, reserved) 
  Bit [5]: set to 0   (not used, reserved) 
  Bit [4]: set to 0   (not used, reserved) 
  Bit [3]: set to 0   (not used, reserved) 
  Bit [2]: Overheated  0 = Normal 1 = Overheated 
  Bit [1]: Standby   0 = Normal 1 = Standby 
  Bit [0]: Ready    0 = Not Ready 1 = Ready 
 
 = , i.e. the ASCII character [3Bh].
