Matt Perks borrows a clever trick from high-end screens used for color grading in their latest custom build.
The answer, surprisingly, was yes, but it took a lot to make it happen, and there were still some performance compromises. The first problem that Perks had to deal with when creating a dual-layer LCD display was neutralizing the effects of polarized filters,
which help improve the image quality of LCD screens but get in the way if you’re putting one panel over another . Removing them wasn’t an option, but a simple layer of tracing paper sandwiched between the two was enough to solve the problem...The whole point of layering two LCD panels was to block light, but the added layer of tracing paper also reduced the intensity of the light so much that it was difficult
to produce an actual image. The solution was to build an upgraded light panel behind the dual-layer LCD screen, which then required even more layers to diffuse the LED lights, which meantcooling, courtesy of four big fans on the back. On top of all of that, each LCD panel still needed its own controller, resulting in a custom screen measuring several inches deep.
turned off. Brighter areas had more saturation and intensity, too, but overall, even with the upgraded light panel sucking more power, the custom screen still wasn’t as bright as either of the LCD screens used to build it originally were. It also exhibited some unwanted artifacts around fine details, including some noticeable blooming around white text, and almost a drop shadow effect on black text.
