I iso9001 New Member Feb 2, 2005 #1 Hi. I dont know much about LCDs. But I'm looking to find out what a specific format of an color LCD I have is. I have no part number and I cant open it up. All I can see is that there are 9 wires going in, but I think this is an input set AND an output set. I have 2 conenctors (4+5) that make this: Red Green Blue White Red/Black Green/Black Blue/Black White/Black Purple The obvious guess would be that it is some kind of RGB deal. However, I'm not sure about the White wire on each set.... maybe an alpha wire ? This LCD was taken from a larger unit that I think went in an car. Ideas ?

I iso9001 New Member Feb 3, 2005 #3 I think I might have found it, I think it might be the same as VGA or some form or it anyway Red Video Green Video Blue Video Horizontal Sync Vertical Sync Red GND Green GND Blue GND Sync GND Does that make sense that an automotive LCD would use the same video form as VGA ???

Click to expand... You're really asking that the wrong way round, it should be "does it make sense that VGA uses the same connections as an RGB monitor". As VGA is just an RGB monitor, it makes perfect sense to use similar connections. RGB monitors predate VGA by many years.
