Currently, this project is on hold as I work on more interesting ones - I will most likely come back to completing these pages when I have a new burst of drive in this direction. However, you're still welcome to pop into our chatroom and ask questions - you will likely get help there!

Why laptop displays?
Laptop displays are in this interesting niche where we could be using them so much more, if only we knew how. They're small, thin, featureful and portable - yet easy to get and cheap. They're way more powerful than small MCU-connectable SPI/I2C LCD screens, more lightweight and power-efficient than desktop LCD monitors, significantly cheaper than portable monitors... In fact, when you buy a portable monitor, what you get is essentially a laptop LCD with a controller board slapped on top of it, in a nice case and with a not-so-nice pricetag.
There's a lot of uses for laptop screens!
- Workbench displays for testing and datasheets
- Portable monitors for work on the go
- Outdoor monitors for kiosk applications
- Arcade machine displays
- User interfaces for SBC-powered equipment (i.e. a home automation console)
- DIY digital picture frames and smart mirrors
- Server closet displays for debugging
- Video walls
- Art installations
You might very well be unaware that you could really use a couple of small and cheap displays somewhere on your hacking journey! For instance, here's a "desk duty" laptop of mine I use for datasheets and movies every now and then, which came with a low-quality 1366x768 screen. Its usability was vastly improved by putting a decent MT6820-driven 1650x1050 screen in front of the original one and using that as the main screen:
It seems obvious that we should be able to give any old laptop display a new lease of life. However, sadly, hobbyists do not know how to do that, and information available on the Internet often boils down to "just buy a pre-made controller". I aim to reach a point where you can pick up any LVDS/eDP screen and quickly read up on everything that makes it tick, even if nobody programmed a controller for it and put it up on eBay - and then be able to follow tutorial to get it up and running, whether it's with a converter board, or maybe your SBC's or motherboard's LVDS output, or maybe with the Raspberry Pi DPI interface!
