A friend donated me this old laptop, which had a broken LCD. The laptop was old but it worked just fine. I had no intention to spend money to get it repaired, it just would not worth the money. Instead I just removed the screen from the body of the laptop and used the laptop as a HTPC connected to a TV.

Then the screen part was pretty much useless, I could have just trashed it, but I just kept it, just in case I could do something with it. Then I had this idea that I could turn it into something useful.

It turned out that it is very easy, and very useful if you're into drawing. It is a light board/table for drawing, it is very cheap and portable, you can easily carry on your backpack with your books.

Step 1:

Take the old laptop apart, and separate the screen completely off the body of the computer.

Thanks for the idea! I reused a Gateway display and it works beautifully.<br>
<p>That's awesome! I'm so glad that you made it!</p>
<p>Very interesting. Even though my 10.1&quot; LED panel came with a driver that didn't have a datasheet available anymore, I could still get it to work on full power by delivering 12v to the LED panel and 5v to the ENA(ble) pin. Made a voltage divider so that I could hook up everything to 12v.</p>
<p>awesome!</p>
Thanks, it's fun to do. However, the next step for me would be to make a PWM controller like you did with a rotary encoder or something alike.
<p>i have same problem for datasheet , but backlight of screen is led so can you help me ? , are the pins standard for all screens ? </p>
Hi, most of the pins are standard. Could you upload a clear image of the board? Maybe I can tell you which connections are to be used :)
<p>I wrote you through private message. I hope that you can help me</p>
<p>Check out Step 7, there is a video with instructions on how to figure out the pinout of your inverter by yourself. </p>
<p>Hey my LCD screen is from HP Netbook. It don't have any inverter. Just a board of circuit behind it. How to deal with it?</p>
<p>It's probably a LED screen, you can make it work as well, you just need to find the correct voltage to drive those led string. The led connections should be a narrow ribbon cable coming from one of the sides of the screen or thin wires.</p>
<p>I don't have a screen from an old laptop, but I do have an old flatscreen from an old computer. Do you know how to make that into a light table? The power goes directly into the screen from the power outlet. My problem is, that when I turn it on, it says NO SIGNAL and shuts down. How do I make the light stay on?</p>
<p>I also have some trouble trying to find the data sheet of the chip there are 3 rows and I can't tell which one is the right number and non of the 3 numbers give datasheets..</p>
<p>If someone could help me I it would be greatly appreciated thanks</p>
Hi Guys, if someone could help me find a data sheet for my chip that would be much appreciated! Thanks!<br>
<p>I got LCD inverter &quot; M300NINT-B V1.0 &quot; with the IC of MP1010 .... but the problem is the LCD inverter connector has a 12 Pins and the IC is too far from the connector ... can you help me to figure out the schematic of this.Thanks :D</p>
<p>Hi. I have an Nec/Tokin D7312-B001-S3-1 and i cant figure it out. can someone help me identify the pins please. Would really appreciate the help. Thank you!</p>
<p>added one more pic. on the chip i have TB153B 74N. i searched for that everywhere but couldn't find it. maybe someone can help me with this. Thanks for the time effort.</p>
<p>you wanna try to find the datasheet of the black chip near the bottom connector.</p>
<p>added one more pic of the connection that was coming from the motherboard</p>
<p>Hello! I would like to use an led display from the hp g62-460tx laptop however, I have no idea on how the led driver circuit is constructed. I failed to find any tutorials or other material on google (all I could find were tutorials on led driver circuits for single or a few led light bulbs) to assist with the driver circuit. </p><p>Could someone please direct me to a resource which I could use to construct the led driver circuit for my laptop's led display?</p><p>Any help is greatly appreciated.</p>
<p>You can figure out how many leds are in series and in parallel on your backlight, then just build a constant current led driver, or even get one of-the-shelf, or a simpler cheaper resistor dropper, current limiting, energy inefficient but it should be fairly easy that everyone could build one.</p>
<p>I absolutely cannot seem to find a datasheet for my inverter (Sumida IV11145/T-LF on the board, mp1017ef and/or mps 0511 on the controller, just fyi). I was curious what you thought about grabbing one of these 'universal' inverters for the project: http://www.newegg.com/Product/Product.aspx?Item=9SIA76H2GT4831&amp;cm_re=universal_lcd_inverter-_-9SIA76H2GT4831-_-Product</p>
<p>I was considering one like your newegg one.</p><p><strong><a href="http://tinyurl.com/AmazonCCFL-LCD-4-lamp-inverter" rel="nofollow">http://tinyurl.com/AmazonCCFL-LCD-4-lamp-inverter</a></strong></p><p>The universal inverters should work and simplify hook up. I was told by a retailer that a 4-lamp unit would even handle just 2 lamps if that's all you need it for. You know how many lamps you have by how many connectors are hanging from the bezel. I'm modding an AC LCD monitor to run on 12vdc and just ordered a two lamp module which matches exactly. </p><br>http://tinyurl.com/AmazonCCFL-LCD-2-lamp-inverter <p></p>
<p>Cool deal. Yeah, mine is 2 lamps, I was only looking at the 4 lamp on newegg because it was actually cheaper than the 2s on there, so thanks for that amazon link! Think I'll order that and get back to work on this one.</p>
<p>i have problem here, i damaged the inverter, so how can i do?</p>
<p>In Step 8, you have diagrammed what appears to be a .22uf capacitor. Is that required? I've followed the instructions, both with and without a potentiometer, and my ccfl screen is not lighting up.</p>
<p>my old laptop is hp pavilion <strong>DV6000</strong> but i cant find the datasheet for the inverter chip </p><p>MSC1692AIPW 0634c </p>
<p>This is what I found, not sure if those are pin compatible, but check if at least it make sense.</p><p>http://www.datasheetbank.com/datasheet/Unspecified1/MSC1692.html</p>
<p>Thank you, wasn't exact, but I got it working. Any ideas on the 6-pin input versions?</p>
<p>I'm having a bit of trouble understanding the &quot;wiring&quot; portion. I'm a bit of a electrical newbie, but I think with a little guidance I could make it work. Anyone able to help with a bit more explanation. Mainly steps 5-8 I am getting totally lost, I can find the data sheet but I am still just baffled on the &quot;19v, and 5v logic&quot; portion of these instructions</p>
<p>Sorry that I took this long to get back to you,</p><p>I've been busy, but I decided to make a video explaining more about the reverse engineering part.</p><p><iframe allowfullscreen="" frameborder="0" height="281" src="//www.youtube.com/embed/k-5O0olni80" width="500"></iframe></p><p>Hope this helps</p>
<p>Great!! Unfortunately I'm not very good in electronics :( I disassembled a lap and found this: <a href="http://www.alldatasheet.com/datasheet-pdf/pdf/189068/MPS/MP1010B.html" rel="nofollow">http://www.alldatasheet.com/datasheet-pdf/pdf/1890...</a></p><p>I identified the pinout, someone might draw the instructions to create the input circuit? thanks!!</p>
<p>This is perfect - I have three laptops that I can't use! Now they can help me out more! Thanks for putting this together.</p>
<p>Hi, saw this month's ago and saved it so I could attempt when I had time, so now I've started and discovered that Toshiba is a little different than Acer. On the Toshiba unit I am using there are 6 pins (8 wires) in the inverter connector and all of the wires are blue(see photo) so no color coding, I have to figure out position, also the pinout labels are different for the IC on the inverter board. </p><p>This is probably simple for you but I'm bumfuzzled as to which wire connects where on your circuit. </p><p>Really want to get this done to digitize some 8x10 negatives from my fathers time in the Navy.</p><p>Thanks so much for your help!</p>
<p>Check out Step 7, I wrote more on Reverse Engineering using the picture you sent.</p>
<p>I'm really sorry to took so long to reply, but for some reason I'm not being notified about new comments. I found the datasheet of the IC, I just need to see the bottom side as well because there are vias poking through the board.</p><p>This is probably the pin out, but I can't guarantee without seeing the bottom layer and do another tests to make sure if it is correct.</p><p>If you could check the resistance with a multimeter that would make things more clear. Like check resistance between directly between pin 20 and the pins I marked as VCC should be a zero resistance path. Do the same for other pins. STBY should be similar to a ENABLE pin but the opposite. DIM is what you want to control the brightness, but this one I couldn't trace it fully because the via goes to the other side, but I suppose it is the remaining pin, the the two vias (?) are joint together on the other side.</p><p>Again, I'm sorry if this answer is too late, I hope you make it. </p>
I made one of these using an old dead lcd tv with a cracked screen. Stripped out the busted insides, added a twin inverter (original was part of dead psu board) wired it all up to a 12v 2amp psu and jobs a good 'un. <br><br>Wired up a relay and 2 push buttons as i had no normal switches and its still running perfect.<br><br>Now for that dead laptop....<br>Wah Ha Ha ha........
<p>made one with an old lcd monitor that i had no use for, just separated the lcd from the <br>backlight and left the powersupply in the monitor and rewired the ps on to a switch and the brightness to a pot to adjust the brightness of the ccfl in the monitor.</p>
Great instructable, may I ask what voltage cap you used.<br>Thanks for the inspiration, I have mine all pulled apart and starting to re-assemble but would like to double check what you used.<br>Thanks<br>Gordon
<p>Use at least a 25v or more on the input. on the output it can be just a 10v cap, or more.</p>
<p>very nice and educational, i can use also larger panels from defective lcd monitor from destops!</p>
<p>I would assume that you can also use plexiglass which can be bought, in my city anyways, at OSH or Home Depot. Excellent instructable man!</p>
<p>I used regular glass because it is more durable and more hard to scratch, and don't get matte with paper and things sanding it, and was more accessible here. But you could use acrylic glass, I guess it would be lighter than glass.</p>
<p>Absolutely beautiful! </p>
<p>Man, this is one of the reasons I love this website. </p><p>Great idea!</p>
I had left a comment a few days ago. loved the instructable then and got my proof of concept done last night. Still have to add a pot, switch, and probably dc jack I was testing on a pc power supply in the video. <br><br>thanks a million for your instructable I would never thought of this and it's actually insanely useful for my girlfriend. <br><br>http://youtu.be/LA2TxpPPlnc<br><br>You sir are amazing!
<p>that is so cool!</p>
<p>You shouldn't need the 5v reg, just use a couple of high value resistors as a potential divider as the voltage is only for signal level, you could even just use 1 on the other side of the potentiometer. VCC -- reistor (5v) -- potentiometer (0-5v) -- GND</p>
<p>Yeah, I tested it using a voltage divider, resistors are cheap. I had this 78l05 laying around, they are pretty cheap and very common, using a regulator, you could probably power it with a 12v supply instead of the traditional 19v without any modification. This makes it more versatile if you want to maybe battery power it or use a different power supply.</p>
