Running 10-bit panel on standard 6-bit LVDS

I've wanted to test this idea out for a while.

The LG LP156WF3 is the 10-bit LVDS RGBLED IPS panel that was used in the HP Dreamcolor and Dell Premiercolor models. I found its datasheet here: http://www.datasheetspdf.com/datasheet/LP156WF3-SLB2.html

I compared that to the standard LG LP156WF1's datasheet here: http://www.datasheetspdf.com/datasheet/LP156WF1-TLC1.html and came up with this adapter idea: http://imgur.com/a/RUvB9 to adapt the panel to work in, maybe, a Thinkpad T510.

How close am I to something that would actually work? Is it true that the extra LVDS lanes directly correspond to the extra bits, and I can just omit them, or is it more complicated than that? Might I need to alter the EDID so that the panel presents itself as 6-bit instead of 10-bit? Would the backlight part of the adapter work, or will I end up just blowing a backlight fuse?

Constructive thoughts are appreciated.

 

Yes.

Might work, but you still lack the I2C signals, which are the ones who control the back-light. So if anything has to be put in front, this is your show-stopper right there.

The omitting and the working is up to you if you decide to give it a try. There might be fail save that would prevent it from working. OR and this might actually be worse - it would work, but since it's made to be and work with 10bit (8bit), it might not look as good as you expect.

Fitting a proprietary display in a machine that wasn't meant to run it, is REALLY... everything - insane, time consuming, money consuming, nerve consuming, might waste a good part of your test machine and etc. I hope you get the idea. That's what I got from trying to run an RGB LED in my CCFL Aspire 5920G. Also, that's why with my current build I went the other way around - found the best display ever put into a laptop, got the laptop in question and started building around it. Even though there are drawbacks, it is FAR... again, everything - easier, cheaper and etc. not to mention that it works properly.

If you still read, the "easier" way is to find the cables and the color board (CB) and try to wire it to DisplayPort (since this is what goes from the MoBo to the CB and then it is converted to LDVS). Why easier is in quotes you might ask? Try finding these cables (MoBo -> CB and CB -> display) and the CB. Good luck!

 

Thanks!

So you don't think it's likely that there's a "default" state for the the backlight if I omit those signals? That's what I was hoping would be the case.

 

Not in my case. I doubt that here would be any different as well.

 

HI,
have you ever came up with any adapter to change to lp156wf3 to standard lp156wf1 type of LCDs. I have excess of lp156wf3 and i am trying to figure out some how i can covert.
thanks
Dave.

 

I have not, unfortunately. The image in the post is the most I was able to come up with.
