In this video we show you how you can make your own kinda transparent LCD display. We know it leaves something to be desired, since it's not super transparent, but we'll show you how anyways. If you want to make your own, we have the LCD we used for sale (linked below). We also have a real transparent OLED display which makes for a pleasing aesthetic.

Looks good.

@borisgoldammer8092 2 года назад

Great video, thank you. Do you think it is possible to replace both polarizers by polarizers used in photography to gain even more transparency?

@Crystalfontz 2 года назад

It's possible. You'd want to experiment with their orientation to get the best trade-off between visibility and transparency. It would be a fun experiment.

@Maisonier 2 года назад

Did you see the "new" display of Sun Vision "Featuring RLCD Technology" ?? Are you able to replace the backlight with a mirror or any other reflective material to convert/make own RLCD ? some kind of DIY.

@ladron6161 6 месяцев назад

smartglasses with this kind of screen with HUD would be perfect imo

@Crystalfontz 6 месяцев назад

You'd probably want incorporate a lens to get the focus up close. We'd love to see someone build it.

@ashutoshtechnology 2 года назад

Thanks 😊

@antospin4004 3 года назад

Can complex graphics and other HUD features be displayed through this display? Awesome one! I'd like to use it for a smart goggle application, suggest?

@Crystalfontz 3 года назад

You can display any graphic you want, but consider the resolution of 128x64 pixels. It's not really transparent enough to see through it clearly for goggles. Optics are tricky, I'd try some different displays and lenses and see what works best for your design. Good luck!

@Band1tBat Год назад

Very neat! If one were to replace the backing with, let's say a one-way reflective window tint, could that theoretically allow a one-way transparent display (image on the display visible from the front, and can see through the back on the other side), with whites to display correctly in the screen? I'm trying to figure out how I could use transparent displays as eyes in cosplay, and was disappointed that sourcing TOLED's seems nigh on impossible 😞

@Crystalfontz Год назад

In theory it sounds possible. It might be difficult to see through, also the pixels on the display are dark not white. We have a small TOLED for sale on our site which may work better for this: www.crystalfontz.com/product/cfal12856a00151b-128x56-transparent-oled-screen

@Band1tBat Год назад

@@Crystalfontz Ah yeah, those are definitely some good points I'd not considered. As for the TOLED, I actually had come across that, and it looks very neat! However I'm afraid the project I'm currently planning would require full colour displays.

@borisgoldammer8092 2 года назад

And one more question: Does this screen, or one of a similar size play back the composite signal of a FPV Camera like JINJIEAN 1280? I connected a small camera to a small screen via an Arduino but if I would not need the chip I would be very happy. Best, Boris

I am working on a transparent smartphone prototype. But the polarizer of the lcd is wayyy to opaque . It basically makes it useless , once i remove the backlight. Could you please suggest something....

@Crystalfontz 3 года назад

@topkek3409 4 года назад

Hi, I’m looking into using a 5” raspberry pi touchscreen for a transparent tablet project, if I remove the backlight and polariser film will a damage the touch screen? I don’t know much about the inner workings of these things! Thanks 😊

@Crystalfontz 4 года назад

Hi, It's definitely possible you will damage the touchscreen. but touchscreens are attached to the front of a display while the backlight and rear polarizer are on the back. You'll want to be careful not to cut the touchscreen tail traces. We haven't tried this hack on a display with a touchscreen, but let us know how it goes if you do!

@topkek3409 4 года назад

Crystalfontz America, Inc. Hi, thanks for getting back to me. I’ll have to look up some diagrams etc to see how the specific screen I’m using is put together. If I can actually get it to work I’ll upload a video of the prototype.

@jeupare8894 2 года назад

Is there a particular reason that after removing the backlight on the LCD, the light coming through looks blurry? Is it just due to the type of LCD or a camera artifact? Like if you wanted to make something like the 7 Shade Sunglasses, could you use this method?

@Crystalfontz 2 года назад

The polarizer is what causes that, but you won't be able to see the letters on the LCD without it. We're not familiar with the 7-shade sunglasses, but it looks like it uses an LCD light valve, you might take a look at those.

@Herp0 Год назад

how small of a LCD can I get? then if I were to shine a led thru it, would it work? the same way a laptop LCD display projector build works?

I think an LCD light valve may be what you're looking for. Here's a list of the smallest displays we carry www.crystalfontz.com/products/smallest-lcds-oleds-and-epaper-displays.php

Hello buddy !I need a transparent LCD to use but without any light can I make a 42 inch display transparent which can be visible in day without backlight

@Crystalfontz 4 года назад

Hi Josh, You would probably be better off using an OLED since they don't have/use backlights. Each pixel is individually lit. If you happen to have about $20k sitting around you could try this: www.lg.com/us/business/oled-displays/lg-55EW5F-A

@oimatewhatyouonabout8526 4 года назад

do you think these would work well if used as a display in a pair of goggles

@Crystalfontz 4 года назад

You could certainly try! This display is not as see-through as our transparent OLED (www.crystalfontz.com/product/cfal12856a00151b), and there are some issues with how the eye focuses, but we're not experts on that. If you make goggles with a display, send us a link!

@_underscore_9271 3 года назад

The oled works pretty great if you add some sort of magnifiers to help the eye focus, and an lcd like this one works too, (with the magnifiers) but is a little harder to make out

@Marc2OVER 4 года назад

Can you make a touchscreen transparent display?

@Crystalfontz 4 года назад

Hi Marc Allen, You could, though we haven't tested it. Because touchscreens are applied to the front of a display, removing and replacing the rear polarizer as shown in this video would not affect the touchscreen. You do need to be extra careful not to cut the touchscreen traces. If you make one, send us a link- we'd love to see it!

@miguelangelbarton2536 4 года назад

@Crystalfontz 4 года назад

LCDs need both polarizers to display. Here's a video that shows the concept: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ydRZkLK7S-w.html

How is the backlight on the CFAG12864U3-TFH connected?

It's electronically connected via the A and K tabs, physically it's bonded. If you want one without a backlight we have a -NFH version. www.crystalfontz.com/product/cfag12864u3nfh-128x64-low-power-graphic-monochrome-lcd

You'd need an awfully large display to make a window, and a huge quantity of polarizer. And then anything displayed on the LCD would be difficult to read if there was any light behind it. But if you do it, we'd love to see it!

@@Crystalfontz Nope, they're talking about MSLA printer. You project UV light through a transparent display. The dark pixels mask out the UV light while the "white" pixels let the UV through. That's how most SLA printers work now, since lasers and optics cost so much more.

@nitinkak8177 2 года назад

Will it work with Arduino UNO?

@Crystalfontz 2 года назад

The I/O voltages have to be 3.3v for this display to work. The standard Arduino Uno uses 5v logic, so you would need to shift the voltages down to avoid damaging the display.

@benbir.ucubeyim. 3 года назад

Can we make a transparent oled display?

@Crystalfontz 3 года назад

OLEDs don't work the same way. In an OLED each pixel is individually lit, so it'd be a much more involved process, probably not a DIY project unless your pixels were an inch wide or something huge.
