lcd panel computer case free sample

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.

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.

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.

You are now ready to assemble everything. In this case, the controller fit nicely in the hard drive compartment, so I glued it there and fed the ribbon cable through the hole in the inside of the case. That way it was pretty much hidden inside the case.

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!

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

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!

Really neat. I saw the same snowblind case and wanted it but too expensive. I also saw someone who made their own using a USB monitor. But I like your setup better.2

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!

Hey, great work on this project. I wanted to buy the snowbind case but couldn"t justify the cost. I have the same case and I ended up picking up the same monitor that you used in your project.

Is it possible that you post or send me photos of the inside of the case when you have this installed? I"m just a bit confused on how you wired up everything?

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) ?

Thanks! So I actually bought one of those adapters, as well as an internal USB 3.0 to USB A port and tried it that way, but I couldn"t get it to work reliably. You might have better luck than I have, but I found it simpler to just run the cable through the case. I just removed one of the PCIE slot covers, and ran it out through there, so opening and closing the case is not a problem.More CommentsPost Comment

If you want a secondary screen but can’t quite fit one onto your desk, you might want to check out ASRock’s latest invention — a PC side panel display.

PC owners have all that space on their chassis, and nothing to do with it. As long as you’re willing to give up being able to easily peer inside the case (and admire the RGB light show, if that’s your thing), you might like ASRock’s 13.3-inch Side Panel Kit. This is essentially a monitor, similar to that in a laptop, that is attached to the inside of your case.

As the panel is installed within the chassis, your case needs to have a side panel made of transparent tempered glass. It has to be sturdy enough to hold the screen, but it also needs to be see-through so that you can see it in the first place.

You could use it to simply monitor your PC’s temperatures and speeds, or you could turn it into a proper secondary screen for productivity or entertainment. Granted, needing to view it through the case will probably diminish the experience a bit, but it’s still a fun gadget if you’ve got limited desk space and want an extra screen. If you do get one and plan to use it for productivity, you might need to re-think the placement of your PC case to avoid constantly having to turn and look to the side.

As of right now, only ASRock boards support this side panel. Tom’s Hardware reports that only some of the best motherboards for Intel and AMD will qualify, including the Z790 PG Lightning, Z790 Pro RS, Z790 Pro RS/D4,  Z790 LiveMixer, Z790M-ITX WiFi, Z790 PG Lightning/D4, Z790 Steel Legend WiFi, B650E PG-ITX WiFi, and lastly, H610M-ITX/eDP.

LCD Spec: 19” transparent TN LCD side panel display with 1280 x 1024 resolution enabling the complete customization of the side panel. Users can configure the digital display to feature video wallpaper, images, or system temperatures in real-time

Many Apple products use liquid crystal displays (LCD). LCD technology uses rows and columns of addressable points (pixels) that render text and images on the screen. Each pixel has three separate subpixels—red, green and blue—that allow an image to render in full color. Each subpixel has a corresponding transistor responsible for turning that subpixel on and off.

Depending on the display size, there can be thousands or millions of subpixels on the LCD panel. For example, the LCD panel used in the iMac (Retina 5K, 27-inch, 2019) has a display resolution of 5120 x 2880, which means there are over 14.7 million pixels. Each pixel is made up of a red, a green, and a blue subpixel, resulting in over 44 million individual picture elements on the 27-inch display. Occasionally, a transistor may not work perfectly, which results in the affected subpixel remaining off (dark) or on (bright). With the millions of subpixels on a display, it is possible to have a low number of such transistors on an LCD. In some cases a small piece of dust or other foreign material may appear to be a pixel anomaly. Apple strives to use the highest quality LCD panels in its products, however pixel anomalies can occur in a small percentage of panels.

In many cases pixel anomalies are caused by a piece of foreign material that is trapped somewhere in the display or on the front surface of the glass panel. Foreign material is typically irregular in shape and is usually most noticeable when viewed against a white background. Foreign material that is on the front surface of the glass panel can be easily removed using a lint free cloth. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store.

A touchscreen or touch screen is the assembly of both an input ("touch panel") and output ("display") device. The touch panel is normally layered on the top of an electronic visual display of an information processing system. The display is often an LCD, AMOLED or OLED display while the system is usually used in a laptop, tablet, or smartphone. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers.zooming to increase the text size.

Touchscreens are common in devices such as game consoles, personal computers, electronic voting machines, and point-of-sale (POS) systems. They can also be attached to computers or, as terminals, to networks. They play a prominent role in the design of digital appliances such as personal digital assistants (PDAs) and some e-readers. Touchscreens are also important in educational settings such as classrooms or on college campuses.

One predecessor of the modern touch screen includes stylus based systems. In 1946, a patent was filed by Philco Company for a stylus designed for sports telecasting which, when placed against an intermediate cathode ray tube display (CRT) would amplify and add to the original signal. Effectively, this was used for temporarily drawing arrows or circles onto a live television broadcast, as described in US 2487641A, Denk, William E, "Electronic pointer for television images", issued 1949-11-08. Later inventions built upon this system to free telewriting styli from their mechanical bindings. By transcribing what a user draws onto a computer, it could be saved for future use. See US 3089918A, Graham, Robert E, "Telewriting apparatus", issued 1963-05-14.

In 1972, a group at the University of Illinois filed for a patent on an optical touchscreenMagnavox Plato IV Student Terminal and thousands were built for this purpose. These touchscreens had a crossed array of 16×16 infrared position sensors, each composed of an LED on one edge of the screen and a matched phototransistor on the other edge, all mounted in front of a monochrome plasma display panel. This arrangement could sense any fingertip-sized opaque object in close proximity to the screen. A similar touchscreen was used on the HP-150 starting in 1983. The HP 150 was one of the world"s earliest commercial touchscreen computers.infrared transmitters and receivers around the bezel of a 9-inch Sony cathode ray tube (CRT).

In 1984, Fujitsu released a touch pad for the Micro 16 to accommodate the complexity of kanji characters, which were stored as tiled graphics.Sega released the Terebi Oekaki, also known as the Sega Graphic Board, for the SG-1000 video game console and SC-3000 home computer. It consisted of a plastic pen and a plastic board with a transparent window where pen presses are detected. It was used primarily with a drawing software application.

In the early 1980s, General Motors tasked its Delco Electronics division with a project aimed at replacing an automobile"s non-essential functions (i.e. other than throttle, transmission, braking, and steering) from mechanical or electro-mechanical systems with solid state alternatives wherever possible. The finished device was dubbed the ECC for "Electronic Control Center", a digital computer and software control system hardwired to various peripheral sensors, servos, solenoids, antenna and a monochrome CRT touchscreen that functioned both as display and sole method of input.stereo, fan, heater and air conditioner controls and displays, and was capable of providing very detailed and specific information about the vehicle"s cumulative and current operating status in real time. The ECC was standard equipment on the 1985–1989 Buick Riviera and later the 1988–1989 Buick Reatta, but was unpopular with consumers—partly due to the technophobia of some traditional Buick customers, but mostly because of costly technical problems suffered by the ECC"s touchscreen which would render climate control or stereo operation impossible.

Multi-touch technology began in 1982, when the University of Toronto"s Input Research Group developed the first human-input multi-touch system, using a frosted-glass panel with a camera placed behind the glass. In 1985, the University of Toronto group, including Bill Buxton, developed a multi-touch tablet that used capacitance rather than bulky camera-based optical sensing systems (see History of multi-touch).

The first commercially available graphical point-of-sale (POS) software was demonstrated on the 16-bit Atari 520ST color computer. It featured a color touchscreen widget-driven interface.COMDEX expo in 1986.

In 1987, Casio launched the Casio PB-1000 pocket computer with a touchscreen consisting of a 4×4 matrix, resulting in 16 touch areas in its small LCD graphic screen.

Touchscreens had a bad reputation of being imprecise until 1988. Most user-interface books would state that touchscreen selections were limited to targets larger than the average finger. At the time, selections were done in such a way that a target was selected as soon as the finger came over it, and the corresponding action was performed immediately. Errors were common, due to parallax or calibration problems, leading to user frustration. "Lift-off strategy"University of Maryland Human–Computer Interaction Lab (HCIL). As users touch the screen, feedback is provided as to what will be selected: users can adjust the position of the finger, and the action takes place only when the finger is lifted off the screen. This allowed the selection of small targets, down to a single pixel on a 640×480 Video Graphics Array (VGA) screen (a standard of that time).

Sears et al. (1990)human–computer interaction of the time, describing gestures such as rotating knobs, adjusting sliders, and swiping the screen to activate a switch (or a U-shaped gesture for a toggle switch). The HCIL team developed and studied small touchscreen keyboards (including a study that showed users could type at 25 wpm on a touchscreen keyboard), aiding their introduction on mobile devices. They also designed and implemented multi-touch gestures such as selecting a range of a line, connecting objects, and a "tap-click" gesture to select while maintaining location with another finger.

A resistive touchscreen panel comprises several thin layers, the most important of which are two transparent electrically resistive layers facing each other with a thin gap between. The top layer (that which is touched) has a coating on the underside surface; just beneath it is a similar resistive layer on top of its substrate. One layer has conductive connections along its sides, the other along top and bottom. A voltage is applied to one layer and sensed by the other. When an object, such as a fingertip or stylus tip, presses down onto the outer surface, the two layers touch to become connected at that point.voltage dividers, one axis at a time. By rapidly switching between each layer, the position of pressure on the screen can be detected.

Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. The change in ultrasonic waves is processed by the controller to determine the position of the touch event. Surface acoustic wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.

A capacitive touchscreen panel consists of an insulator, such as glass, coated with a transparent conductor, such as indium tin oxide (ITO).electrostatic field, measurable as a change in capacitance. Different technologies may be used to determine the location of the touch. The location is then sent to the controller for processing. Touchscreens that use silver instead of ITO exist, as ITO causes several environmental problems due to the use of indium.complementary metal–oxide–semiconductor (CMOS) application-specific integrated circuit (ASIC) chip, which in turn usually sends the signals to a CMOS digital signal processor (DSP) for processing.

In this basic technology, only one side of the insulator is coated with a conductive layer. A small voltage is applied to the layer, resulting in a uniform electrostatic field. When a conductor, such as a human finger, touches the uncoated surface, a capacitor is dynamically formed. The sensor"s controller can determine the location of the touch indirectly from the change in the capacitance as measured from the four corners of the panel. As it has no moving parts, it is moderately durable but has limited resolution, is prone to false signals from parasitic capacitive coupling, and needs calibration during manufacture. It is therefore most often used in simple applications such as industrial controls and kiosks.

In some designs, voltage applied to this grid creates a uniform electrostatic field, which can be measured. When a conductive object, such as a finger, comes into contact with a PCT panel, it distorts the local electrostatic field at that point. This is measurable as a change in capacitance. If a finger bridges the gap between two of the "tracks", the charge field is further interrupted and detected by the controller. The capacitance can be changed and measured at every individual point on the grid. This system is able to accurately track touches.

Unlike traditional capacitive touch technology, it is possible for a PCT system to sense a passive stylus or gloved finger. However, moisture on the surface of the panel, high humidity, or collected dust can interfere with performance.

In addition, devices are often placed on surfaces (desks or tables) and tablets especially are used in stands. The user may point, select or gesture in these cases with their finger or thumb, and vary use of these methods.

Before you start shoving wires into ports in the back of your PC or the sides of your laptop, stop and take a closer look at those ports so that you know what you"re looking at. Modern computers handle video via an HDMI port, but older computers feature a variety of other ports:

DisplayPort: A DisplayPort was originally designed as a superior video port to older VGA and DVI ports, but is far less popular on modern computer systems than the HDMI port.

DVI: The Digital Visual Interface was originally designed by the Digital Display Working Group, and was next-generation to the inferior VGA port. Many older computers have one of several configurations of the DVI port.

VGA: Older computers typically come with the famous blue VGA port. The 15-pin VGA has been used for computer video for many years, but has been largely replaced by the newer video ports like Thunderbolt and HDMI.

Typically, if your computer has two ports on it, the video card should be capable of sending an output signal to both. If there"s only one port, then it probably can"t. However, your desktop might have available slots for additional video cards. So, even if there"s only one port on your desktop, don"t hesitate to pop the cover and check for any available slots for another video card.

If you"re still not certain whether your computer can support dual monitors, another option is to research your graphics card. First, look up the brand of your graphics card.

If you want to close your laptop"s lid, but still use your external monitor, for example, to watch a movie, you have to change your laptop"s power options, which are hidden in the Windows 10 Control Panel.

Cleaning a computer screen isn"t as difficult as you might think it is. Here"s what you need to know about how to clean your display, what to use, and cleaning it safely.

It doesn"t have to be this way. Cleaning your computer or laptop display is remarkably simple. What"s more, it only takes a few minutes. When you"re done, you"ll have a shiny new display as good as the day you bought it.

Don"t have these things to hand? Don"t worry---you can also clean your computer screen with standard household products. Start off by making your own screen cleaner, using isopropyl (rubbing alcohol) or white vinegar, and distilled water.

These devices attract more grease and dust than static LCD displays. As such, you"ll need to clean them in a slightly different way. Hybrid device touchscreen displays are cleaned in much the same way as standard tablets and smartphones.

Meanwhile, if you own a CRT, follow the same steps, but remember that you can use glass cleaner. The case and display should also be cleaned with an anti-static cloth.

Once your greasy, dirty screen is cleaned up, you might feel ready to start using your computer again. But you shouldn"t stop there. It"s time to completely clean your computer. Using a notebook? Here"s how to clean your laptop and keyboard.
