Laptop screen to PC
« on: September 08, 2010, 04:40:26 pm »
Is there a way to hook a laptop screen (decased and unattached to the rest of the laptop) to a PC VGA connection?

I mean you could splice the wires if you knew what you were doing.
Anyone done this? Im thinking about a small screen for the DMD on my Pincab and I already have a laptop screen im not using

This comes up semi-frequently.

Short answer: No

Long answer: ASSUMING you have documentation for it (they're all different)...
If it's one of the new-fangled Displayport based ones (I've NEVER seen one), yes.  You just need to find the right cable to hook it up to a video card with Displayport (note: NOT analog VGA).

If it's the more normal LVDS based type, you're pretty much screwed.  You will need something that will output LVDS with the exact timings required by the display and on the proper connector (there are lots used, but some are more common) and proper pinout (one of the popular connectors has two incompatible pinouts).  Input format is whatever this magical device accepts, probably HDMI/DVI but maybe analog or Displayport.  I'm sure something like this exists, but I've never seen one that wasn't a professional novelty that cost something like a kilobuck.

If it's an OLD one that takes TTL parallel digital RGB, similar comments to LVDS based apply.  I've seen boards to do this a little more frequently, but again they're intended for professional one-off applications, and as such the volume is low, and the margin is high (meaning price is sky high).

I'm actually about to build a hopefully low cost board to do this for the latter style.  If you get me a datasheet for your module, I may be able to make it compatible.
(My definition of "low cost board" probably differs from yours)
