Recycling laptop screens
Laptop screen 2nd life

On-wards with recycling

First project

So I had an old laptop ( Dell PP09S ). It had a good screen, so why not continue using it. The driver circuits from the laptop are so integrated to the motherboard that recovering those did not make sense. However, for 40 dollars I found on Ebay a complete driver kit. The driver offered a HDMI input and many more. Perfect for my needs.


  1. Find out what model of screen is used in your laptop.
  2. Order the correct driver kit if available. If not you are out of luck.
  3. Take the laptop a part and carefully extract the screen.
    • No connected circuits are going to be reused.
    • Take care to not break the connectors.
    • Also, be careful with the screen, behind a tape marked "Don't Touch", there is a lamp containing mercury vapor, you don't what to break that!!
  4. Build yourself a support structure for the screen and the circuits.
    • Ideally you will have a structure that is not flammable (yea I know).
    • I did not take in to account the possible issues of having a common ground between the component as I have not had to deal with that issue. However I think one should exercise care in that area. In my case, a quick test with a voltmeter shows that their is no voltage differential between the mounting screws of the components.
    • You should use plastic mounting studs for the button board. The foil on the bottom does not allow for conductive studs.
    • Check the other boards as yours may be different.
  5. Connect it up.
  6. Power it up and voila. My kit requires a 12V 4A power supply. I had one from an even older PC.

Second project, and older monitor

This project was to modify an existing monitor (Samsung SyncMaster 941SW) to accept an HDMI input. The monitor had been left unused because of this shortcoming. I purchased the correct kit, based on the screen model, removed all the old circuitry and then mounted the new controller on the outside shell of the unit. I did this because the space in the monitor was tight and I did not have the tools to modify the metal housing. I ended up  with a 7-of-nine look ;-)

I could have bought and external DVI to HDMI converter. With the installation of the new controller I think I gain in versatility. I do not know if the converters are any good. I also gain and input and output audio channel. This is the kit I bought: and its "documentation"



The circuits that comprise the kit are not approved by any organization such as the CSA. I don't completely trust them. They can be useful and fun but they should be used with care. By the way the same can be said of a Raspberry Pi.
