Dear all.
I've made big LCD tablet. The original post is http://bumhee34.tumblr.com/post/96151688002/diy-21-5-inch-wacom-lcd-tablet.
Let me start my build.
Actually, I've started to build this since this May.
But...sadly, I burned my vga controller once, cracked LCD once, and broke the tablet itself one time.......haha.
So, it took me long time to build this. All my salary has been invested in this build T^T
But anyway, I finally complete this build in success!! Yeah!!
So, before to start build log, I wanna show you the final shots.

What I introduced to you is not that great, but it is gorgeous Smiley

Front view


Back side

Pen holder


Sketchbook pro test


Windows journal test



Let me start my build log.
What I've made is Wacom tablet which has 21.5 inch FHD LCD.
This is the spec of this DIY tablet.
  • Wacom tablet : Intuos 3, second hand PTZ-1231w. But I broke down it one time...so I bought it again.
  • LCD : 21.5 FHD LCD from aoc2269. Also broke this one time Sad
  • Case : Made by ABS and arcryl
  • Tempered glass : 0.7mm thinckness. I was so lucky to buy this.

Anyway, I could make this using intuos 4, but it is expensive.
So i bought second hand ptz-1231w in ebay.
When I got it, I was surprised due to the size.
It is massive and big, physical size is more than 24 inch monitor.
The mosaic is my hand, and it is not fuck sign Smiley Just to focus on the tablet size !!

Next is aoc2269 monitor...is fake!
Actually, I tried to test e2243Fw monitor first, since somebody in bongofish forum recommended this, and I could not get a second hand aoc2269 at that moment.
In fact, this monitor is useless. Please do not try with this monitor.
You will only have massive jitters and I guarantee that you cannot resolve it.


But anyway, we can learn how to disassemble a 21.5 inch monitor, cause all 21.5 monitors have a similar structure.
So I wanna share how to disassemble it.
With a tool like this or plastic card, you can easily unhold small latches leading to uncover the besel.

With carefulness, you can finally take the screen off.
As you can see, we must remove the metal plate on the backside.


First, unflip the LCD board, and unhold all latches using a proper tool.
Be patient, and do not hurry. Or, you will crack the LCD.
All beginners normally fail at this moment.


After taking off the metal plate, you can find LED backlight attached on the plate.
Using a sharp card or knife, you can disassemble the LED backlight.


And then, place it in the original position.
Since you do not have the metal plate, you should fill that part with something like foamex.


Let me come back to the tablet.
It is really easy to disassembly ptz-1231w.
You just need to unscrew screws.
Wow.. this is so large..


Anyway, my original plan was to use the origianl tablet case.
So, attach the vga controller (or called AD board) like this.



And cut the tablet cover



And color the cover


And failed in coloring... Sad


Anyway, let me go on.
The tablet consists of two parts, one is the signal reciever which was shown in above, and the other is the circuit board to control the reciever.
The board next to the AD board is the wacom circuit board.
Anyway, the tablet structure was like this at the first time.


And now, it is easy to assemble all together.


Until that time, I was so happy.
But found that cannot resolve crazy jitters with any method.


So it was going to be in garbage can...(my closet)
Bye bye e2243Fw.. (Does F stand for Fuxx?)


So I ordered a second hand AOC2269 monitor, and the tablet had been kept in somewhere in my room..


Luckly, I could reassemble the monitor and could recover it in original state.
Anyway bye bye....


After waiting several days (more than several actually....),
I got AOC2269 in cheap price in 중고나라. (very famous second hand market in Korea)


Let me disassemble it. Now it is easy for me! (식은죽 먹기, easy as much as eating cold porridge?? anyway it means damn easy)



After uncover everything that you could remove



And remove all screws that you could remove



And unhold every latch


go on..!


Finally you can take the screen off.


The main disadvantage of AOC2269 is that it has built-in SMPS instead of using AC power adapter.
Why is this disadvantage? Cause it is big and emitts much electromagnetic noise, so it is not that good for DIY tablet.
Anyway, wanna finish this work with this monitor.

This shows the LED FPC cable. Took this pic not to forget the way to plug in right direction.

Anyway after removing every screws, you can find SMPS and AD board.
The SMPS is under the black part.
AND, I'd burned them !!! hahahahaa....
I do not know why, but maybe the board is cheap one....
There was spark after screwing.
But, luckly I could buy SMPS and AD board on taobao.com.
They sell everything....
But the bad news is that, I also cracked the LCD !!!! Yeah!!!
So, I bought a second hand AOC2269 again....in 중고나라.
I was so poor...T^T and am poor now Sad


Anyway, stop crying and let me move on.
This pic shows LVDS cable. Looks strong.


Unplug LED cable carefully.

LED FPC cable is too short, so I need to extend it.
Buy 0.5mm pitch 10 pin FPC cable, and extend them with a tool like this.
I do not know how to call it in English, 날크립 in Korean. Anyway, this is the easiest way to extend FPC cable.


So, two FPC cable could be extended by using above tool. Face the conection parts each other, and clip them together.


This pic shows how it is extended.

Anyway, after removing metal plate on the screen.
I meet the LED backlight again. Hello, long time no see!


Anyway, i should fill the metal plate part with other stuffs...
Cause I didn't want to buy foamex, I used several arcryl parts in my room.
It looks dirty, but ok. Anyway, this part is not visible.


Assebmling all together, and doing test.
 

Now, I design my case using AutoCAD, and send the drawings to a private company who have CNC and lazer cutting machines.
Anyway, after few days, I got my case.
It looks like this. The bottom is made by ABS, while other parts are made by arcryl.


The bottom has a hole and scoopped(?) part. (Please correct my English)
The hole is for the connector for the wacom plate and the wacom circuit board.
And the scoopped part is for FPC cable connector for buttons.


From this pic, you can see why i made above parts.


Anyway, you can glue ABS and arcryl very tight with chloroform.


And bore holes for screws using dremel and tapping screw.


Like this


Taping the wacom plate to prevent electric short.

And install foamex with knife cut to hold LCD.

But my hand is not fixed...

Anyway, LCD is fixed like this.
And to prevent it fall off from wacom plate, I glued them with strong double-sided tape.


With the trasparent top cover. It will be colored in(by?) black.


And before to order 0.7T tempered glass, I ordered 1.65T tempered glass.
I will explain why I changed the tempered glass later.
But anyway, I ordered a wrong thing. The size is 500x323, but I ordered 500x232 by mistake Sad

Anyway, just install it to see whether the thickness is ok.

And, I tested withough glass and top cover.
When turning on, you can see AOC logo.

Through the hole on the bottom of the case,


The wacom plate inside the case and the wacom circuit board are connected.


And bore holes to hold SMPS and AD board.


At this moment (taking the picture), I had no idea that this AD board will be burned....
You see that scsrew?? On that screw, there was spark and both SMPS and AD board are fired!!!!! Shit, they must use cheap circuit board.

Anyway, withought knowing the future, I was taking pictures....
Sayonara...


And I also attached a monitor arm. In that picture, it was attached in reverse way Sad I modified it in final result.


Anyway, it is tightly held by screws.


So.... I thought this might be finished soon.... at that moment..


My hand may know the doom of this tablet... This pic looks sad..T^T


Yeah, yeah... until that moment, i was so excited.


Anyway, bore screw holes for top cover.



Boring holes is really boring.....be patient.


And color the top cover in black.
Actually........I recolored it more than three times.....
At first time, due to poor sandpaper work, the paint was ripped off, so recolored.
And then, during my DIY beam projector work, I chopped the top cover with my beam projector by mistake .... ... so recolored.
And......There were lots of mistakes during finish spray work.
So recolored...T^T Maybe I am stupid Smiley


Anyway, let's move on again.
This pic shows how i gonna hold buttons with screws.
I bored holes for screws on arcryl parts and glued on the back side of the top cover.
The shiny part is touch script.


Now, i can hold the button like this.


Took this pic with excited mind.
Didn't know that it would be take more than one month further...


Still excited, I go on coloring the tempered glass. haha


The button parts are not completed, yet.


The opposite part is same.


To hide the headless screw holes, I covered them with black stickers.


Time to attach the tempered glass with very strong double-sided tape.
I didn't know that this will cause a disaster....


Anyway, turning on the desktop.


And then, I found a very important stupid problem in my build.
When I tried to draw a straight line, the line is not drawn continuously but drawn with segments with some pulse shown in the example pic.
I found two reasons.
First, the panel is somewhat thick, so by adding 1.65T tempered glass, it is more difficult to transfer the pen signal onto the wacom plate. However, this is not a big deal.
Second, this is a real important issue. Since my case is purposed to reduce the thickness than that of the original wacom case, the insulatoin metal sheet is very close to the wacom plate. AND this leads to eletromagnetic interference between the wacom plate and the metal sheet.
By experiment, I found that the distance between them should be longer than 2mm. So I should disassemble all, and should insert 2mm thickness on the back of the wacom plate.
And,.....here is the sad story.
During disassembling them, I broke down my LCD... I tried to rip off the tempered glass from LCD, and they already glued very tight.. Sad

This shot is just before to break down the LCD....Sayonara....


AND, one more disaster...
I told you that I broke down ptz-1231w also. Here is the shot.
During test, I plug in and plug out the wacom circuit board a lot, and one of the connection pin was ripped off!!!! DAMN!!


So I tried to do emergency surgery with soldering.


And it had been dead with my cursed hand. Bye bye...


Sayonara again... to my closet.
So, I bought the monitor, and the wacom tablet again.
Start again from beginning... Jesus..


After few weeks, I bought AOC2269 again in 중고나라. And restart the work.
This is how to hold my pen. You can buy this from internet. Do not know english keyword, but in korean, 다이어리 펜 수납.
Anyway, red color is for man.


This is how to cover the back side of my tablet.


So, it has one power plug cord.


And one DVI port, and one VGA port.


Of course, chloroform is used again.


If you inject it on the edge you wanna glue, they are soaked in the surface.
ABS and arcryl can be glued tight with this method.


So, the SMPS and AD board are positioned like this.


The OSD button for the screen is attached on the side.


The button is extended using arcryl, and will be colored by black.
But, by mistake I lose one of them Sad It's missing upto now, I do not know where it is haha.


Anyway, the back side is colored by white surfacer and finished by non-glare finishing spray.


During this work, ptz-1231w is arrived from ebay. I love ebay so much.
And from now on, I am working very carefully.


This is the missing button. Where is it?


So after assebmling them, I can test without any problems.


At that time, there were lots of jitters since I hadn't found good screen frequency.


Anyway, at that moment, I was so tired and frustrated by many mistakes and my frined kept teasing me for my many mistakes.
So I took this picture, and send him. haha.
Dear Kim. this pic is for you, my best friend Smiley


The pen holder is red, but buttons are white....
I cannot stand it anymore!


So? Recolor them in red with non-glare finish spray Smiley


Touch script parts


Now, I can assemble all together.
But the tempred glass has 1.65mm thickness.
And as i explained before, 2mm thickness is inserted more than I expected to cure the big problem.
Therefore, the glass is projected out. So it looked ugly.
So, I contacted to the owner of the company who sells tempered glasses, and I explained my situation.
It is rare case to sell thin tempered glass to normal person, but he agreed to make 0.7T tempered glass for me! Wow thx for him a lot, I didn't need to remodel the case.
The 0.7T tempered glass costs more than 100$. but worthy.


Anyway, I need to wait more than two weeks again to get the tempered glass. Finally, I got it!! Yeah!!
This is really really thin, and it is like the tempered glass in iPad air.
Anyway, I tried to color it, and failed twice Sad
I hadn't noticed the reason for the failure.
And found that.... My room has quite low temperature due to air conditioner. When I tried to color it, I go out with it.
And the outside temperature is much hotter than my room, so there should be lots of moisture congelations. That was the failure reason for coloring.


Anyway, after founding the reason, I go out when sunny day and colored it with success.
To color it well, you need to do with patience. Spray it little for lots of time.


Finally...Success!!!!
Wow, it looks gorgues T^T
This touches my heart.


Fantastic back side!! with one button missing Smiley
With the monitor arm, i can adjust screen slope (is this correct word?)


I like my design Smiley


There is litte mistake on coloring, and there is a damaged part by my beam projector.
But it looks cool~! yeah!


Boot on Windows 7, I can use this as a monitor.


But, when I plug the tablet USB, blue light is on, that means the tablet is ready!


Very sexy pen holder (in my opinion)


I can become an artist with Sketchbook Pro (though I am not good at painting haha)


And it is jitter free! I adjust the screen frequency not to have jitters.
To do that, you must have a nvidia graphic card.


Finally, I wanna show you this. http://youtu.be/ipTl4P8zwVI

This is the end of story of my 21.5 inch wacom LCD tablet.
See you!!

That is one of the most beautiful graphics tablets I have ever seen.

I'm actually inspired to try something like that after I get some experience with my current build.

It is a most beautiful build, though a troubled one. After having read your battles, I feel lucky with my builds (the finished ones went smooth).

You're a true inventor!

Beautiful work.

My favorite parts:

-Working with a CNC laser cutting fabricator to create a one-off form.
-Going through the trouble to source a sheet of tempered glass.  That's a step beyond!
-Working out how to paint that glass.  Congratulations on working out how.  The result looks sweet!
-Defeating the Jitters.  (Can you offer your parameters and settings and the Nvidia card you used?  I think others might find that very useful.)

The only drawback to this build, (and it's one I encountered myself)...

After buying all the parts, often more than once...  How much cheaper was this than just laying out the cash for a Cintiq?

I've personally spent many hundreds of dollars on parts, screens, Wacom boards and used Tablet PCs over the years.  I've not added it all up, but I'd be willing to bet I could have just bought a Cintiq for about the same cost.

However...

I actually think I came out ahead by a long way.  Not only do I now have some great digital drawing boards that I regularly work on, but for the same price I also now have a TON of experience and knowledge in the field of engineering of computer technology.  It's like I took a hands-on college course and also got a Cintiq at the end of it.  This fills me with confidence and that increases my general feeling of self-worth and happiness, (which were already quite healthy to begin with. Smiley ).  -And you know what?  I think that doing my own inventing and problem-solving makes me a stronger writer and cartoonist, in a non-linear way.

-I remember, many years ago, reading an article about Lucasfilm, (waaaaay before those sucky prequel Star Wars films), back when Lucasfilm still created amazing works, (like the "Young Indiana Jones Chronicles").  -They didn't want to hire animators who only animated.  They wanted people who had interesting hobbies which informed their work.  Guys who liked to re-build motorcycle engines, for instance.  The logic being, your art cannot be a good representation of the world if you don't know how the world actually works; if you never get your hands dirty or get out of your own head.

So good on ya!

It's a great looking project and it sounds like you had fun!

Very thx for your warm comments.
I forgot my setting, so i should look it up later. And then, I will write down nvidia setting.

Money,, it took me around 1100USD? I guess. Luckly i bought many stuffs in very cheap price in ebay or in korean second-hand markets.
So, anyway it is cheaper than Cintiq.

This is my 9th build if i remember correct.
Actually, I am not an artist or someone related to that kind of job.
I am just a normal Ph.D candidate in nuclear engineering.

How did i have this kind of hobby?
At first time, I'd felt that wacom tablet pc had soooo small screen, so I couldn't satisfy when I do note-taking.
So? I'd decided to make my own note-taking system with big screen. That was my first build with intuos 3 ptz-930.
At first time, the build was so weird, and had lots of problems.
So I'd rebuilt it modified it, and I found that that kind of work gave me lots of fun!! so much fun and happiness.

After then, I cannot stop build other tablets.
I've had no idea that I would like this kind of stuffs. Now, I am a real fan boy of DIY, especially in electronics.

Making a tablet, making it better, and understanding it, everything makes me happy.

That is the only reason that I keep making it eventhough there were lots of troubles.

As my major is nuclear engineering, this DIY hobby may be my second job in future or just hobby.
I also love my major, this also gives me lots of fun! I cannot give up both Smiley

Thx again.

Hello, I had a question, Bumhee34!

Did you happen to get a picture or remember the model number of the panel that you pulled from the AOC2269? This monitor doesn't seem to be available in America, and I'm trying to replicate your seemingly immaculate build. (The AOC2269 looks exactly like the AOC I2269Vw though, so I suspect they may be the same thing.)

Thanks,

Hi procersapientiae, welcome!

It could be that bumhee34 didn't write the full screen number? Perhaps the panel was just marketed that way for ease and the sticker on the back showed the extra letters? I had a look for this model without the i...VW parts and I didn't find much, I would suspect that bumhee34 did actually use the AOC i2269VW screen, as even on AOCs website (Europe) they only show the I2269VW and the I2269VWM varients - which by the way both use the same LM215WF3 panel (with the 'M' version having more connectivity); I imagine that the panel also probably has the suffix (SLK1) based on the number of panels that major trade sites have available for sale.

Of course bumhee34 can clear this up for you though.

Hello, Aerendraca,

I think Bumhee34's might actually be an "Alphascan AOC 2269", which seems to be really expensive ~$280, compared to the I2269Vw, and seems to be a Korean model? (But it looks exactly the same!)
(see http://www.ebay.co.uk/itm/171325104856)

It may or may not be different from the others. I sent AOC an e-mail on Saturday morning asking about the panel for those, and also the I2267Fw, but haven't gotten a response yet.

Thanks for the panel model, which btw, I'm quite curious how to that info. I searched for hours yesterday to no avail x.x

Well there seems to be a whole bunch of confusion over Alphascan. It appears that Alphascan is a Korean display company with a somewhat confusing history. It's really unclear but either Alphascan is part of AOC (or vice versa), or this is a collaborative marketing strategy aimed at the Korean market; I can't find any specific conection between the companies although I don't speak or read Korean.

Based on the screen specs alone though I would suggest that you can fairly certainly assume that these are the same panels, and that the controller hardware has been tweaked to allow additional connectivity, perhaps a bespoke OSD. Thing is there's only a handful of actual 'panel' manufacturers in the world, LG and Samsung being two of the biggest, and, as far as I know even AOC don't actually produce TFT panels just the complete package that is the monitor, so I'm happy to stand by my statement that they are all likely to use an specific LG panel.

It's worth asking AOC but I doubt they will give anything away about the panels.

I got a response from an AOC rep, he had forwarded my inquiry up to a product manager, and I got this response,

'Yes, all "2269" series use the same panel.'

So, hopefully it works without jitter! I'll post a new thread in the build logs once all the stuff comes in.
