repurpose lcd screen factory
Well, not only can you save a piece of old technology from the scrapheap, but you also can repurpose a mundane blank screen into a range of intriguing projects.
Not only can you now spend a rainy afternoon or two taking apart your busted LCD screen, you’ll get that insider’s view of all the interesting circuitry that goes into these electronic devices that are a part of everyday life.
If you are an artist or photographer, you will be well aware of the importance and expense of lighting. But what if we told you that you could make a powerful, portable DIY light panel from an old LCD screen?
This amazing LCD screen hack produces a high-quality panel light that radiates daylight quality light. An equivalent panel light can cost well over a hundred dollars!
We have to admit we were skeptical about this LCD screen project, but the walk-through provided by the BrunaLab team in Florida was convincing. These scientists were more than qualified to take apart an old Panasonic screen to make a StarTrek-worthy infinity table.
This tutorial is a little more than purchasing some IKEA table legs to screw into the screen to make a coffee table (the original hack). Emilio Bruna decided to take his project in a high art direction to produce an infinity lighting effect with blue LEDs.
We love the futuristic results of the LCD recycling project and the low costs. Emilio Bruna’s project came in at $73 all in, with a wacky blue lighting pattern that kept his kids glued to the coffee table screen!
If you are a tech and electronics enthusiast, you will be aware of the Raspberry Pi revolution. These remarkable single-board computers have the processing power to be put to work in a wide range of projects, including partnering with your broken LCD screen to make your high-end digitized smart mirror!
There are loads of tutorials for this LCD screen mirror which vary in cost, complexity, and overall swagger. The majority of them, place the LCD screen behind a two-way mirror and rely on the WiFi-enabled Raspberry Pi3.
The basics of this build include combining an old OHP projector and laying a stripped-down LCD on the glass of the projector. The OHP does all the hard work of projecting your movie or game.
Also, the LCD does age quite quickly in this arrangement as the light passing through the denuded screen damages the LCD. However, you can definitely gather the family round for a decent movie night or two before it all falls apart!
Raspberry Pi comes to the rescue again as the perfect partner for repurposing your own screen. After all the Raspberry Pi is a computer with no screen to call its own.
This project totally blew us away. How cool is a transparent screen that you can see through while you stream films or play games?! Though this project is not for amateurs it is possible to requisition a discarded LCD TV and create a see-through screen.
To achieve this, you will need an expert takedown of the TV, sepearating every single layer of the screen and building up a custom design and housing.
A broken LCD screen is a potential hazard to your health and the environment so it is important that you handle the screen safely to prevent injury or harm.
Though the screen has liquid crystal, the amount contained within a busted screen is small and unlikely to cause a hazardous spill because it is viscous.
HDMI capability is essential for me to get the best quality out of a raspberry pi. The high cost you mentioned is much less than the cost of a larger screen for the portable breadboard capable raspberry pi laptop/breadboard lab I"ve been planning. Thank you for your post. BTW , I dont usually use Ali Express so the link you provided are very useful.0
I order the LCVD chord whatever to use my mondor for by gateway laptop the LCD V chord day they sent me is huge I"m gonna try counting the pins inside it of each one Could you help me and what do I need to do
Can you use the monitor controller card from the laptop I got the screen out if? I am just learning electronics so I am just experimenting with different ideas. Thank you for a great instructable.
I"ve seen this project a while ago and now that i found an unused laptop screen I got more into it, so I wanted to know if any of the controller boards that you shared would work with any screen model, or do i have to search for a compatible one?

Got an old laptop lying around? I do – just haven’t gotten it to the recycler yet. Here’s the thing, though: I’m guessing most of its parts are working just fine, and could be reused by someone who knows what they’re doing. That’s not me… but the GreatScott! Youtube channel has a video tutorial for removing the LCD screen from that old laptop, and putting it to use.
While analyzing the strength properties, slightly smaller values were observed for the concretes with LCD admixture, in relation to the reference concretes CI.0 and CII.0. The differences in the obtained values are differentiated, exhibiting no clear tendency. They are most pronounced in the tensile strength test; however, due to the high coefficient of variation (over 10%), they cannot be subjected to a comparative analysis. Generally, it can be stated that lower values were usually found in the concretes with LCD addition. Such observation can be explained both by a higher air content in the concrete mixtures with LCD admixture (the considered concretes exhibited diversified consistency with low degree of liquidity within two classes), as well as the conchoidal fracture of LCD grains. The conchoidal fracture, due to its glassy and smooth texture, deteriorates the mechanical adhesiveness of cement paste to aggregate granules, despite its low porosity found while examining the interfacial transition zone (ITZ). Nevertheless, the low share of the admixture should reduce its significance. It should also be emphasized that extending the maturation time substantially mitigates the differences in compressive strength values. Following 90 days of maturation, all concretes reached the same class. which is especially prominent while applying the CEM II/B-S 42.5 N cement that is characterized by a slower improvement of the strength parameters in relation to CEM I 42.5 R.
The obtained correlations can be described by the equation y=0.39x2−0.02x−2.23, which is characterized by a coefficient of determination R2 = 0.83 and relatively low errors in the intercept (respectively 28%, 25%, 28%). The higher the water-tightness, the higher the frost resistance and the lower the mass loss. The reference concrete CI.0 is characterized by the lowest water-tightness (deepest water penetration), which corresponds to the highest mass loss during the water tightness test. An increase in LCD admixture to 2% resulted in 3-fold decrease in the mass loss of the samples.
Based on the research of Batayneh et al. [64] concerning the impact of various waste materials on the properties of concretes and hardened concrete, it was found that the use of aggregate made of recycled concrete, due to the shape and texture of the grain surface, significantly reduces the workability of the concretes. Similar observations were made when using crushed plastics. In our own research, the impact of LCD additive with significantly smaller amounts and completely different mineralogical and chemical characteristics did not significantly affect the consistency of the mixtures.
The use of 20% recycled plastics or concrete aggregate according to Batayneh et al. [64] reduces the compressive strength compared to reference concrete with natural aggregate. Despite the small amounts of LCD addition used in our studies, similar relationships in compressive strength values were observed in the early maturing periods (see Figure 5). However, after a longer maturing period (90 days), the same compressive strength classes of the tested concretes were obtained.
As a result of research of Mahesh and co-workers [65] regarding the impact of waste from polyethylene plastics, it was found that despite the reduction of early compressive strength of tested concretes (5–10% of the used waste), their compressive strengths after 28 days were comparable to the reference concrete [65]. Similar correlations were observed in own research after the use of LCD as an additive (Table 10).
The 100,000-hour figure assumes that every diode will be running at full brightness, consistently — which, on an LED screen, is virtually never the case. The lifespan figure can also be misleading because it indicates when a diode degrades to half-brightness, not completely dark. Many other variables affect an LED display’s lifespan; you can’t rely solely on the number on the diode spec sheet.
“The reality is, your screen can often last significantly longer than 100,000 hours,” says Kevin Izatt, a senior product manager in Samsung’s Display division. “We’ve had displays that have been up for 15-plus years with more than adequate brightness. Because the diode is actually only one factor in the lifespan of your LED display.”
The quality of your display’s power supply — and how hard it drives the diodes — can have a significant impact on your screen’s lifespan. The other components being powered, such as fans and electrical components, have their own lifespans as well, which are also impacted by the power supply.
“Something like airflow is very important,” says Izatt. “You need a screen that has good cooling, and a design that allows heat to flow out of the back through vents.”
To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program. Samsung will come on site to remove your existing display and provide a discount on a new LED bundle kit.
Traded-in LCD displays that are still operating will be refurbished and resold, and your business will receive a cash rebate. Nonworking displays will be recycled and their parts reused.
As you plan your LED signage rollout — or an upgrade — learn how to configure and tailor your screens’ real-time messaging with an integrated CMS in thisfree guide. And if you haven’t decided what kind of display is best suited to your current project, compare all ofSamsung’s LED displays.
It might come off as a surprise but about 98% of an LCD/monitor can be recycled to extract useful material including plastic, copper, and other metals. The plastic removed from an LCD monitor is used for manufacturing new products while the circuit boards are smelted to extract metals. The wiring in the monitor can also be stripped to extract copper and rubber. All these materials can be recycled instead of getting wasted and polluting the environment. Moreover, some LCDs and monitors can be refurbished to be used again by extending their lifecycle. Only an expert in electronic recycling can do this through a meticulous process. Trust our team at Hummingbird International to do this for you, be it commercial waste disposal or residential ewaste disposal.

Liquid Crystal Displays (LCDs) have replaced Cathode Ray Tubes (CRTs) as the main display devices in recent years. To satisfy the increasing demands, billions of LCDs are manufactured annually. As more LCDs are produced and used, the amount of LCD waste is increasing at an alarming rate. Current treatment technologies can disassemble LCD into multiple components and recycle them according to their materials. However, there is no suitable model for treating LCD panels. Research has repeatedly shown the harmfulness of liquid crystal, indium and other heavy metals which LCD panels contain. As a result an increasing number of countries have classified LCD panels as hazardous waste. Because of this, future processing of LCD panel waste will require on-site burial, burning, or physical disposal, not only increasing processing costs, but also causing environmental damage. This is a huge problem. That is why this recycling technology for waste LCD panels is a kind of revolutionary breakthrough.
The pilot plant handles 3T of waste LCD panels daily, with a liquid crystal recycling rate of 100%, indium recovery rate of more than90% and glass recycling rate of 100%
Liquid crystal is the main component of LCD. It is a chemical with a high unit cost, high stability and low biodegradability. While the harmfulness of liquid crystal is uncertain, its structure contains a large volume of benzene rings, fluorine, chlorine, and bromine, which, if buried, may seep into subterranean water systems and impact ecosystems. Physical processing entails breaking down LCD panels and adding them to cement or concrete, which does not remove liquid crystals and heavy metals from the panels, so they may still enter and harm the environment following rain or washing. Based on environmental and economic considerations, the liquid crystal in the LCD panel should be reused.
To prevent the pollution caused by waste LCD panel disposal, and to control processing costs, ITRI thoroughly analysed the characteristics and reusability of each material contained in LCD panels, and designed a logical separation procedure according to the associations between each material, first separating liquid crystal, indium, and glass, and then developing purification technology for each material which enables the reuse of these materials. Liquid crystal can be reused in new LCDs or liquid crystal smart windows. Indium can be refined as the raw material of sputtering targets. Glass can become a humidity-controlling green building material or heavy-metal adsorption material.
ITRI’s pilot plant can treat 3 tons of waste LCD panel per day of operation, producing 3 kilograms of liquid crystal, 750 grams of indium, and about 2,550 kilograms of glass, which can be reused as humidity-controlling green building material or heavy-metal adsorption material. ITRI’s team uses the pilot plant for technical verification of on-line scrap LCD panels and end-of-life LCD panels. ITRI can build the LCD panel processing center for LCD manufacturers and e-waste recycling companies.
Wondering where you can sell your broken iPhone LCDs? Looking to sell some cracked iPhone screens? Want to make some money from your damaged Samsung Galaxy tablet and phone displays? Sell them to us!
Provided the underlying digitizer and the display itself is still in order, we’ll give you some pretty respectable money for your old and smashed smartphone and tablet screens. Certain displays are worth up to £50!
How much? The prices we’ll pay you for your screen vary- while OEM versions of the newer Apple screens (including the Apple Retina) and more recent Samsung displays are worth the most, there’s some good money to be made from the displays in older models.
Remember that even if these screens aren’t worth anything to you, there’s a good chance they’re worth something to us. There’s no catch, because- unlike most people- we have the experience and specialised refurb equipment to make it worth our time to bother with these screens… and pay you money for them!
We’re based in the United Kingdom, but you can sell us your cracked and broken LCD displays via mail from anywhere in the world. Let us know what you want to sell- via our contact form– and we’ll get back to you with the necessary arrangements.
Like we say, a pile of cracked and smashed screen panels from dropped, broken and generally mistreated smartphones and tablets might not be very useful to you- but we’ll certainly give you good money for them!
Manufacturers of low-cost 3D printers that use the masked stereolithography (MSLA) process are able to build their machines so cheaply because they’re using repurposed smartphone or tablet LCD panels to mask off the UV backlight. Considering the quality you get out of even the entry-level MSLA resin printers, we certainly aren’t complaining about this bit of thrift. But as [Jan Mrázek] explains in a recent blog post, there’s certainly room for improvement.
The problem is that those repurposed LCD panels are, as you’d expect, color displays. After all, even the bottom of the barrel mobile devices moved away from monochrome displays decades ago. But in this case, that’s not what you really want. Since the printer operates on a single wavelength of light, the color filters inside the LCD are actually absorbing light that could otherwise be curing the resin. So an MSLA printer with a monochrome screen would use less energy and print faster. There’s only one problem: it’s not very easy to find high-resolution monochrome displays in the year 2020.
But it was still worth a try. [Jan] pulls the display apart, removes the liquid crystals, scrapes off the color filters, and then puts it all back together again. His first attempt got him a monochrome display that actually worked, but with debris trapped inside the screen, the image was too poor to be useful. He tried again, this time trying harder to keep foreign material out of the crystals. But when he got it back together a second time, he found it no longer functioned. He thinks it’s possible that his attempt to clean up the inside of the display was too aggressive, but really there are so many things that could go wrong here it’s hard to pin down just one.
