Search around the Internet and you’ll find a landfill of forum threads asking how to drive the LCD screen from a dead laptop. The answer is always that there is just no way to do it. That’s because most of them use a Low-Voltage Differential Signalling protocol that just isn’t available through the hardware used in hobby projects. But the appearance of this board could signal that things are about to change. We don’t want to get your hopes up too much. This isn’t an open source project, but it is a piece of hardware that can make LVDS available for the 8, 16, and 32-bit microcontrollers you’re used to working with.
It’s a derivative of a project [Thomas Jespersen] worked on for a customer. It uses an FPGA to implement the LVDS standard used by high-pixel-count LCD displays. It contains enough memory for a full frame-buffer, and includes a Motorola-8080 communication standard. [Thomas] gives a full description of how the setup works in the video after the break. Demonstrations start about 7:30 into the video with an STM32 F4 Discovery board driving the display.
