Case modding took off in the late 90s, and taught us all that computers could (and should!) look awesome. Much of the aesthetic went mainstream, and now tons of computer cases come with lights and windows and all the rest. [WysWyg_Protogen] realized those simple case windows could be way cooler with a neat LCD hack, and set to work.

The concept is simple. Take an old LCD monitor, remove the backlight and extraneous hardware, and then install it to the window in a computer case. When lit from behind via LEDs in the case, the screen creates a ghostly display through which the computer’s internals can still partially be seen. It’s a really compelling effect, and in theory, quite easy to achieve. All one need do is mount the stripped-down screen to the case and pipe it video from the graphics card.

In practice, it’s a little tricky. Disassembling the screen and removing things like the anti-glare coating can be tough to do without damaging the delicate panel inside. The windows typically used on computer cases can dull the effect, too. However, [WysWyg_Protogen] is continuing to tinker with the project and the results are getting increasingly impressive with each iteration. It doesn’t photograph too well, but it looks truly amazing in motion.

We often forget LCDs are transparent in their basic form, as we generally only use them with backlights or reflective backers. They really do look great when used in this transmissive way, though. Video after the break.

Actually beside myself right now. How does this look this good? This was a trash pile monitor and this looks like a 700 dollar case upgrade pic.twitter.com/4yBXlcY921

And here I am remembering the groovy times when people had fish in their case mods

Check out the iBuyPower Snowblind case. A commercial product that did the same. Unfortunately very rare. I think it was only available as part of complete pc from iBuyPower. I tried to get one second hand for some time, but no success. Only source i could find is a shop in the USA that does not ship to my country.

They did start selling them by themselves. I bought 2.

In the ’70s/’80s the future was supposed to be LCD house windows – instead of curtains or blinds you’d have a knob on the wall to darken the windows. These days it would have to be internet-connected with a smartphone app. But sometimes the future never comes.

Or it comes way later than we expect, or only to the few. LCD house windows still exist, just not in most houses. Too expensive and brittle to be of use as normal glass, at least how they normally manufacture it. I’d honestly be curious if it would be possible to convert existing windows. Now I’m gonna go do some searching.

“Switchable glass”, “privacy glass” or, worse, “smart glass” is readily available, but not cheap, for use as interior partitions, doors and windows: it is robust enough to use instead of boring old glass.

But it just changes from transparent to a translucent milky colour, at least all the stuff I found online or have seen in “Grand Designs” self-builds.

Still hoping for an affordable version of the Blade Runner (huge) picture window that has a neutral density filter effect moving smoothly vertically to cast dramatic light over your VoightKampff machine.

I was about to ask. Cant you just sandwich it between to glass slabs ?

At work, we have a conference room with one wall floor to ceiling glass including the door. Overall there’s roughly 20 feet by 8 feet of glass.

The entire glass area is switchably obscured (white) by an LCD film. So, LCD windows exist in that sense. Thought of as a display medium, the resolution is tragically low in that there are a total of 5 giant “pixels” in one row which could be controlled individually but are not.

It ain’t cheap but it is cool.

I recently worked for a company who wrote building automation software for a customer who specialized in making “electrochromic glass”, which is exactly what you’re talking about.

The company that makes the glass is called SageGlass and the glass is extremely expensive, but it has been installed in multiple high-end flagship buildings and can go from fully clear to fully tinted black, or anything in between (not like the frosty white privacy glass).

It was pretty cool stuff, I got to work with very tiny panels of their glass for development purposes and I got to tour the factory where the glass is produced. Absolutely wild stuff, it wasn’t easy to make the glass and they explained the physics behind it but that was above my pay grade.

If you buy a Dreamliner, you get dozens of those windows for free, with a button right underneath to control its darkness. They they even have remote control, which is good because half the seat dwellers next to the windows can’t figure out the button.

For those with more modest budgets, or less storage space than a Dreamliner would take up, you can get the “single pixel display” LCD shutters pretty cheaply. Made (in)famous by Naomi Wu’s “Blinkini” LCD shutter top.

This is used on many new slot machines. They have a transparent LCD in front of a set of physical* reels. Typically the space around the reels is backlit so graphics are displayed there, often doing a convincing imitation of “old school” artwork, 7 segment LEDs etc. Some of them look like they’re supposed to be an old machine that’s been given a technology upgrade.

But when the player his some special bonus, the inside lighting on the reels is turned off and graphics displayed over the now black area, with light piped across by (I assume) some special transparent film. Works like a vehicle with dark windows at night. Turn a light on inside and you can’t see out, but people outside can see in. Park under a streetlamp and you can see out of the car but those outside can’t see in.

Some restrict those graphics to the reel area, some ruin the illusion by displaying the special graphics across the entire panel.

*They’re real reels but what they show has long been computer controlled, virtually expanded to a very large size. The computer in the machine determines which graphic to bring into alignment, or mis-alignment, in front.

.. or they will just layer the transparent LCD on top of another normal LCD to give a feeling of depth and add more interest.

Hot take… We’re never away from our computers long enough these days so we need somewhere else to display the screen saver. :-D

I’d put a proper screen on the side of my case and use it as “the” screen before I’d do this, but I guess if I had one I’d stick on the “souls escaping” clip from Raiders of the Lost Ark on it to freak out visitors.

Very cool. But I just nee a PC case to keep the bits cool inside, as I need to keep my attention on the monitor screen :)

this fad cycles in and out every few years, its neat but it only really works wells on cases where the insides are predominantly white and doesnt look like someone vomited a bunch of junk in a box

Um, sorry sweaty, but this kind of thing increases climate change sea levels and creates more waste in landfills in the ocean near China and India. Please cease destroying the environment and killing manatees. They are a marginalized community too.

he/she/it should be proud of building that construction, not from something else (also colorful)
