I took this Chromebook touch display off of a broken Chromebook.
It’s a SHARP LQ123P1JX33/A01 .
I’ve determined that I would need an eDP 40-pin to mini-DisplayPort adapter for output to the LCD screen, but I’m having trouble finding information for what I would need (if I need anything) for this connection? I assume this is the part of the display that handles the touchscreen. Is it possible to adapt this for external use, or is it not worth the hassle?
Adding a comment in the main thread so OP gets a notification.
Looking at the picture, I think the testpoints with labels next to the connector are directly connected to the connector? If OP can confirm that?
In that case it's a I2C conection, with some extra pins. You can connect that to USB using something like a GT911 converter, found for cheap on sites like Aliexpress and Ebay. However converting the connector can be a pain in the ass, so I would just solder a ribbon cable to the test points and do the same on the side of the converter.
When choosing a converter be sure it's 3.3V and not 5V. So maybe add a level shifter, or choose a converter with a level shifter. The touch screen might be 5V tolerant, but it's a risk to try it.
Yes the test points are directly connected. This seems like the answer I was looking for, so I’ll shop around and try and get that to work. Thank you so much!
