Hi all,

I'm looking at a project whereby i'd need to connect a RPi Zero to a Laptop LCD (Removed from a laptop)

I understand I'd need a controller board and an inverter along with a power supply but I'm not sure exactly what parts would work.

I was looking at the following items:

Controller: https://goo.gl/dbH5hS (assuming it is compatible with my LCD)
Inverter: https://goo.gl/YEvKy4 or https://goo.gl/yuQi32
or could I use the existing inverter from the laptop?

My soldering skills aren't that great, but i could manage some basic stuff if needed. I'd also like to make sure that all the cables are included and from the descriptions, they look like they are.

What do you think, would these parts work?

Thanks for any help.

AFAIAA you only need a LVDS board configured for your specific LCD Panel and a 12V 4 A power supply to provide enough juice. The LVDS board kit should include everything needed.

You need to get the make / model off the back of your LCD panel and find a compatible converter.
As stated by the ebay seller you linked to: send them a message with the make model so that they can check if it's compatible.

Ideally you would not need to solder anything. Just plug in a few cables.

Excellent. That will make my project that much easier.

I'm looking at building a video intercom system, or at lease just a remote video feed to my front door. I just have to wait until I can get a hold of two RPi Zero W's (I have 1 on the way).

Thanks for the advice.

One more question, if anyone knows the answer?

Is it essential to get a model that states compatibility with my screen or will all of the the controller boards work with all different LCDs?

Thanks again for any advice.

There are no doubt hundreds of different LCD standards and hundreds of different LCD controllers all with different electrical characteristics, different connectors and different protocols.

You need a controller that works with your screen or at least one similar enough that it stands a chance of working.

They aren't plug and play devices.

Yes, but the controller may be compatible with more screens than those listed on ebay.
AIUI there are several types / groups of screens that need their own type of controller.
That's why it's important to contact the sellers first.

One item I was looking at was incompatible with all 3 types of screen that I have :(

I have about 9 screens from broken laptops. I think it'd be cool one day to create a huge display out of them and hang it on a wall somewhere.

If a separate inverter is not required, why do some of the boards come with them while others do not?
