1  Screen Tablet malarky / Heyaaaalpppp / Re: Same screen, same tablet as another build yet it's not sensing the pen! on: December 18, 2017, 01:56:30 PM
Okay, my tablet monitor sandwich turned me into a liar  Cheesy

This past sumer is when I last test it. I tried all the screen frequencies back then, had a piece of cardboard behind the lcd inside of it's frame, and paper on the tablet as a sheild. This time around, instead of cardboard I used paper. And now I'm able to draw on a regular peice of glass on top of my monitor. Only problem is, like everybody else, lots of jitter around the edges which makes it completely unusable. I'll try grounding the tcon board to the metal plate of the tablet I guess. Wish me luck!

I have an intous3 12x19 and an AOC2269 just like this build
The only difference is that I'm using regular off the shelf window glass which is approx. 2.4mm

Pretty sure others here have used normal 3mm glass:

http://forum.bongofish.co.uk/index.php?topic=191.msg3069#msg3069

Now the plastic LCD frame of the AOC monitor is about 7.62 mm in height or .3 of an inch
so with my glass (2.4 + 7.62) that would be about 10mm above the wacom antenna circuit board

I can't seem to find whatever the maximum distance is for the pen tip to the sensor board...but maybe it's 13mm according to this post? I really wish all the info was in one place.  Anywho, does anyone have an idea of where I might be going wrong? i don't want to take the LCD out of it's frame, but I can if that's what's required. Just not sure how to make a frame for the led strip yet..  Undecided Any thoughts on all this?

Most of the image in the builds forum don't show up and clicking on them gives a 404.
Yesterday I saw that the website was having issues, but it's  back now. Is there a major problem or something?  Shocked

Maybe I found the answer here in this Korean blog:

Optimal position, tablet coordinates, and monitor refresh rate control also help you tremble.

(Based on the AOC monitor), the scan rate was changed to 51 Hz, except for slight tremors

In the real working area, I felt no tremors, and the pointers fit correctly
Impressed

I hope this helps anyone looking for info on the AOC.

If this doesn't prove multitouch is possible in windows 7, then nothing will  Grin

It looks like someone already wrote a multi-touch driver for windows 7: http://multitouchvista.codeplex.com
Might be a good start, as it's got code examples and documentation. There might be an api to interact with the driver. I know wacom has an api to grab their tablet's data. So what would probably have to be written is an application that just waits for a "pen in range" and "pen out of range" and enables or disables the touch.  Seems simpler now....I guess  Smiley

So there's no other way to have palm rejection and ignore touch input when using the pen?
Do these panels come with any driver software?

I'm not a fan of windows 10 (and avoid it like the plague), but at the same time I can understand you not wanting to fiddle with the software side of things.  I wonder how easy it would be to add a capacitive touch panel for something like a Cintiq 21UX. Would Windows 10 deal with it in the same manner?

Bumhee34: Which screen frequency did you use? It would be a great help to know as I have the same monitor and tablet also.

@metapharsical: Heh, well I kind of trusted your claim of 'no jitter' because you'd just come out of building another cintiq and had some experience with it. I almost bought a screen on ebay because of one guy here claiming 'no jitter' and everyone congradulating him for like 10+ posts. It wasn't until after I'd won the auction and I scrolled down and saw that he did indeed have issues lol! I went through a long refunding process to get my money back on that one....ugg.

I did buy a Dell 2209 though. Noticed it does get rather warm near the vents and the back. Hmm...you say the LEDs didn't fit the oversized frame. I'll have to figure that out later I guess. Sorry for thread hijacking btw. I'll post my own build log eventually lol!

I don't mean to dampen your enthusiasm for working on this project, but I have to ask something. Wouldn't it be easier and cheaper for you to go with the Dell 2209 monitor which had "zero jitter" and do a more thorough LED conversion on it? It seems like you spent more resources, time, and money trying to fix jitter on your newer screen when you already know another screen works perfectly with no jitter issues.

@metapharsical:
I had a feeling that was the screen Grin Uh, if it didn't have a diffuser....how did you get the LEDs to work with it in the first place? Wouldn't it only light around the edges if you did that without one? Also, isn't there a cheaper or easier solution like these LED kits from ebay? Finding a diffuser though, I guess you really would have the scavange broken monitors, it seems pretty hard to find them on their own. I went ahead and bought a 2209W just for the reason of no jitter. No jitter screens seem extremely rare around here Undecided

Which Dell monitor was used in the second Exotiq build? Huh The model number is never mentioned:

Quote
I got the Dell 22" e-IPS monitor and disassembled it.
Pros:

    No JITTER!
    FFCs seem plenty long enough
    4 USB ports
    Great viewing angles!

Cons:

    ***No Backlight Slab!*** There's just a 1" deep box that contains the CCFLs behind the screen.  This will not do!
    Power and Video boards are on the same PCB, this sucks but this doesn't seem to be causing any interference

Could it be the Dell UltraSharp 2209W?
