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

* Bright Dot is defined as dots (sub-pixels) which appeared brightly i\
n the screen when the LCM 
displayed with whole pattern & Bright Dots brightess is defined over 50\
% of the brightness against 
around. (but, Green bright dot is over 30% of brightness against around\

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...

 
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...

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

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]....
