I saw a really cool video of a PC case called "Snowblind", that had a transparent LCD Screen as a side panel. I was amazed over how cool it was. The only problem was that it was really expensive. Therefore, I tried making my own! In this instructables I will go through how I made it, and how you could make your own. The best of all, since it was made from an old monitor that was thrown away, it was basically free! I just added some LED strips on the inside of the case to get better contrast on the screen. You could probably re-use the monitors backlight, but it"s safer and easier to just get some cheap LED strips.
The first step is to disassemble the monitor. The disassembly is pretty well documented in the video I made. I have also added some pictures so you can see the steps. The steps of disassembling the monitor will not be the same for every monitor, therefore I will not go into detail of every step.
You will have to reverse engineer the controller to find the power connections, and solder a new power connector on. This way, you can use the ATX power supply that powers your computer. I used a multimeter, where I had one probe to the ground plane (For example around the mounting screws), and used the other probe to search for 5V or 12V power on the pins coming from the power supply.
First, remove the frame of the panel. It is fixed with clips, so just bend the frame a little and lift the frame up. Next, separate the front LCD from the backlight. For the next step, you will have to be careful. This step involves removing the anti glare film. It is glued to the panel, and therefore it"s easy to break the LCD when trying to remove it.
To remove it place some paper towels on top, and then carefully pour water on it until the towels are soaked. Let it sit for around 24 hours. After 24 hours, try to start pealing the layer from the corner. If it sticks in some places, place a wet paper towel on that space and wait some more.
Then you are done modding the LCD! Now, you can hook it up to the panel and test it. Just be careful with the ribbon cables going from the LCD PCB to the panel.
The side panel of this case fits the LCD perfectly. Just line it up to the side facing the back, and to the top, and use some tape to tape it to the glass. Then, use some vinyl on the outside where the LCD is not covering the glass.
It"s really important to have lots of lights inside the case, to make it easier to see the LCD. Therefore, try to fill the case with even more LED strips.
Now you can carefully mount the side panel back on the computer. You might have to drill a new hole for the thumb screw in the back to make it fit properly.
You can now power up the computer, open the screen settings and set it up for dual screens. You might have to flip the display 180 degrees too. When you have done that, open Wallpaper Engine and set a wallpaper of choice!
I have the same problem, I have read on google that the lcd could also be 3,3v (check if you have 3.3v lanes) so i will be trying to solder a sata cable to it because it comes with 3,3 and 5v connectors but the im not sure if save to use sata cables0
Hey I have a little question, I also have a Dell 1905FP, but I think it"s an older model because I don"t have a ribbon cable but a normal cable with a plug. My problem is that I have peeled off one film but it still looks like there is a second film on the back because it is still a little blurry. But I"m afraid that if I try to pull them off, my LCD display will break. Maybe you have an idea. Thanks in advance
Stunning result ! Bought for 10€ a Dell 1907FPc which is fairly similar to yours. I have trouble identifying the pin layout to find the 5V pin. Did you plug in the power supply to your AC while checking with your multimetter ?0
Great tutorial and video! I"m trying my hand at replicating your process and I even got my hands on the exact monitor. I have reached the point where I"ve disassembled the panel and controllers, and discharged the capacitors from the PSU, but I am a little stuck at this point because I don"t know how to wire up the molex header. I watched your video and saw that you had two wires soldered to the power connector. Which connectors are they and where do they go on the molex cable? Thank you!
Terrific job! May I ask why you would need to remove the front polarizer? If my understanding is correct, both the front and back polarizers are needed in order for the LCD to work properly (i.e., the light gets polarized by the back polarizer first, and then passes through the front polarizer)? You comments will be appreciated!
I tried taking some photos, but I have covered the screen PCB with a cover, so it was hard to see in the photos. I basically just laid it inside the case with a 90-degree angle. I tried drawing it here: (view from the front)0
I think you should have more pics and info about the re- mounting the LCD. After all if you don"t do it right all that work is for nothing. While I understand your wiring diagram, I think that it should be explained and a larger part of this Instructible...for example to get white lite your are powering all 3 lanes (red,green,blue) on the RGB tape.
Hello, Wonderfull project, I have the same case and I would love to do it (if I have time and the screen to the right size). Just a question, can you put a photo of the cable connection to see if it"s easy to open the case ? One little suggestion, instead of connecting the panel to the graphic card (which mean to run a cable outside, why don"t you use a USB to VGA or DVI converter (like this https://www.amazon.fr/Adaptateur-convertisseur-adaptateur-Affichage-multi-écrans/dp/B079L81FRD/ref=asc_df_B079L81FRD/?tag=googshopfr-21&linkCode=df0&hvadid=227894524041&hvpos=&hvnetw=g&hvrand=17927658121409960098&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9055710&hvtargid=pla-442905712462&psc=1) ?More CommentsPost Comment

USB graphics may also be supported by the type of motherboard. For some, the dropshipping mini laptops may have higher RAM than the majority of them, and they may be higher. The main of upshipping mini laptops is the same as those of other USB laptops.
Most of the mini computers offered by the Alibaba.com type are the Bluetooth- Wi-Fi module, also called a Wi-Fi module, and a Wi-Fi adapter is the most type of mini PC. In terms of wireless connection, the Bluetooth connections are supported by the Wi-Fi connection and also supports wireless connectivity. On the other hand of motherboards, the motherboards for support laptops and other devices may use fine Wi-Fi connectors instead of Wi-Fi connectors. Other motherboards support laptops in the form of portable mini computers.

Insert the TF Card to Raspberry Pi, connect the Raspberry Pi and LCD by HDMI cable; connect USB cable to one of the four USB ports of Raspberry Pi, and connect the other end of the USB cable to the USB port of the LCD; then supply power to Raspberry Pi; after that if the display and touch both are OK, it means drive successfully (please use the full 2A for power supply).
