Therefore, read below what he converted, why this happened and why you should still buy a corresponding monitor from the manufacturer instead of building one yourself.
PC enthusiasts are often not only looking for maximum performance for their PC, but also to satisfy their own tinkering instinct. This can be done with custom water cooling or case mods as well as with peripheral devices. But at the latest when building your own hardware parts, this is the end for most users, since the technical know-how and tools for this are missing. But the Youtuber DIY Perks didn’t let that stop him and made a video about his own DIY dual-layer LCD monitor.

His goal was to create a cheaper alternative to an OLED panel by building it himself, which impresses above all with its excellent contrast. For the experiment, he initially disassembled two standard monitors and placed the panels on top of each other. The idea behind it was to only use the panel without the backlight from a screen so that the black display would improve. However, the attempt did not work because the darkening effect was so strong that no picture could be seen. This is due to the polarization layer in the panel.

He solved the problem inexpensively with tracing paper between the panels, so that an image became visible again, even though it was very dark. Therefore, DIY Perks, whose real name is Matthew Perks, decided to increase the backlight. An LED matrix was used, which emanates not only from the edges, but from the entire back of the panel. It also has to be separated again with tracing paper to allow proper light diffusion.
This solved the lighting problem, but the effort is still high. The actively cooled construction in a self-made housing is not a beauty and has advantages and disadvantages. While the contrast is high, writing is very soft and looks unnatural. When gaming, however, the advantages of vivid colors come into their own. However, the creation consumes 250 watts at a relatively low maximum brightness, so it is probably better to use a ready-made OLED monitor instead of daring to build it yourself.
