DIY dual layer LCD: Get OLED black levels for "cheap" and no burn in risk

This work's surprisingly well for a jank job. It looks a bit dim because they used to entry level LCD panels to do this experiment, so the final image isn't going to look very bright they'd need two 1000 nit panels for that. But the improvement in black levels is amazing

Same technology that Sony uses on some of their reference LCDs.
