I cant believe I just found this thread, I heard of the breakdown but couldnt find anything.

Anyway! I really think we should aim in "small stuff" instead of big stuff and expensive like the screen, adding more ram shouldnt be an issue, I mean, shouldnt really be kernel/software related. And the 2nd most important should be the mini-pci express ( I do think it is a mini-pci express ) for a 3g/gps card!

Thinking of replacing the screen with LP101WH1-TLB1

Hello Everyone,

I am thinking of purchasing the LP101WH1-TLB1 by LG to replace the screen currently in the G-Tablet (B101AW06 by AOU). They both have a 40 pin connector and the screen sizes are almost identical. The only dimension that really worries me is the thickness; the LG is 5.3mm while the AOU is only 3.6mm. Does anyone see any other reasons why the LP101WH1-TLB1 might not work?

Since I am a new user I am unable to post a link to the datasheet but if anyone is interested in the LG's datasheet please let me know (i believe a link to the AOU datasheet has been posted)

Thank you,

Angel

AOU? I'm not surprised.

My asus g73 has an AOU, so many peole were complaining. Apparently there were two types, AOU and samsung or something. AOU was the dreaded version to get....lmao.
[G Tablet General] joedhimself:
wouldn't the different resolutions be an issue?
[G Tablet General] leo653:
Do you think the icons will be too small to effectively use the touchscreen?
[G Tablet General] floatpoo:
Any particular reason why you're going with this LCD? According to the spec sheet, the viewing angles of the LG is even worse than the AOU -- 30/30/10/20 vs. 45/45/20/45.
[G Tablet General] leo653:
According to the datasheet I have, this is the viewing angle on the LG.

x axis, right(phi=0°) = 60°

x axis, left (phi=180°) = 60°

y axis, up (phi=90°) = 50°

y axis, down (phi=270°) = 50°
[G Tablet General] floatpoo:
Oops, I was looking at TLB2. Nevermind then.
[G Tablet General] daml:
This is easily fixed with a density tool.

The tegra graphics CAN support the higher resolution too. And there are ways of changing resolution in android.

This screen should work very well...
[G Tablet General] HorsexD:
So is it Pretty Easy Taking out the Lcd and putting it back in? I was gonna buy a New B101AW06 but this time Glossy instead of the Matte one for Better viewing angles and better none washed out colors. I Dont care for glare. This tablet already has glare with the glass front. :rolleyes:
[G Tablet General] daml:
http://www.nbkit.com/Wholesale/prod...n-10.1-inch-LED-1366x768-WXGA-HD__c18093.html

cheap too.
[G Tablet General] cutterjohn:
IIRC If you look through the thread someone already tried a Pixel Qi screen, but the thickness was a problem, and it was also 5.3mm IIRC.
[G Tablet General] orangezero:
blisscomputers.net has the same monitor for $45 plus shipping. won't let me post the link yet.

This place has them a little cheaper. I've never bought a replacement LCD before. Looks like you can call to ask which manufacturer will supply which model #.

On ebay several of the places said they wouldn't know which (glossy vs matte) they would send you.

Someone else mentioned we'd need kernal source to change the resolution, and another mentioned it could be done (assuming he meant in software, or just by changing a setting). If I got this one right now, and it actually works, would it probably just show in 1024x600 and have a black border around it because of the nonused pixels?

Without knowing anything else, I would guess whoever picked the original screen did so because it was about the thinnest available for the price.??
[G Tablet General] daml:
Resolution is set by a kernel option:

omapfb.video_mode=800x600MR-16@60 etc

I await someone trying this screen. :)
[G Tablet General] teknikk7:
So is this possible to change with our current ROM's? I am a newb here. If it is I will order this screen and someone can walk me through changing this option?
[G Tablet General] teknikk7:
Does anyone know the answer to this? Can we edit that kernel option with our current ROM's? Would somone be able to walk me through this process?

Thank you
[G Tablet General] moli13:
Does anyone here know what netbook this LG screen is mounted on so that we can find youtube reviews to verify the better viewing angles? The reason I'm asking is because I found some data specs that listed the viewing angles as about the same or worse than our g-tablet. I'm really not concerned about the thickness. Our case can be modified if needed. I've had mine apart and it is somewhat easy replacing the screen.
[G Tablet General] teknikk7:
I thought the Dell Mini 10 used this screen. Can anyone confirm?

The first gen had 1024x576 then Dell offered a higher res screen of 1366x768. Again, I am just pulling these numbers from memory. I think this is that screen.
[G Tablet General] DanielNTX:
I know that the Dell Mini 1012 and Latitude 2110 uses a standard 1024x600 display. I have one sitting in front of me. I upgraded my displays to 1366x768. If this tablet is upgradable to this resolution, I'd do the same thing.
[G Tablet General] graphicsman:
How are the angles on your updated displays?
[G Tablet General] daml:
Dont suppose you wanna test the screen then? I'm assuming you own both the tablet and the LP101WH1-TLB1 is in your mini 10??
[G Tablet General] daml:
I dont know the details but it is very easy to do.
[G Tablet General] teknikk7:
How are the viewing angles? I know its asking a lot but can you upload a video or pics from different angles? I am about to order this thing as a last ditch effort to keep my gtab.

Also, like the poster above asked. How feasible would it be to swap panels in your netbook into the gtab. I would be willing to compensate say $20 for your time. Maybe others could chip in?

Let me know your thoughts.

--Robert
[G Tablet General] daml:
yes i would also put some $ towards seeing this happen. Also if it works maybe some development of a rom suited to the higher resolution screen.
[G Tablet General] tristanwolf1134:
If anyone wants to tell me what screen we all agree on, I will order one up and test swap it out. I really don't have anything better to do with the tablet now that it has awesome ROMs. Just let me know what we all agree on even if its a couple of different ones.

Trist
[G Tablet General] moli13:
If we can find someone that sells it (just coming into production)

AUO B101EW05 (same company that makes our G-Tablet screen.)

http://www.auo.com/?sn=149&lang=en-US&c=34&n=146

Has awesome specs!
[G Tablet General] daml:
it seems LP101WH1-TLB1 is the one we are most interested in.

good viewing angles. cheap.

1366x768 resolution!!!!!
[G Tablet General] DanielNTX:
I'll try to do a video of the viewing angles soon.

As far swapping panels. I don't think so. It's a pain in the ass to take the screens apart on the Inspiron 1012. There's very fragile plastic clips. On the Latitude 2110, I have a touchscreen bonded to the LCD so that's a no go either.
[G Tablet General] orangezero:
Just going from their specs, seems it uses a bit more energy (to be expected I guess) compared to the one in the gtablet. plus its a bit taller and thicker. Not trying to be a drag, its a good find... it does seem like its made for being a tablet screen with the angles they quote. I'm not sure what a "VA" mode is compared to the TN of the gtablet screen.

seems this might be a good option in 3-6 months when the other tablets using it open a cracked screen replacement market. wish it would be available tomorrow...

good searching.. I think the biggest issue would be that its about 7mm taller in the outer measurement. 230 x 149.7 x 5.2 VS current of 235 x 143 x 3.6

Is there the extra room? I haven't taken mine apart yet.
[G Tablet General] moli13:
I found this website to very helpful. The above model B101EW05 V0 is listed there in the AUO link but the ones being discussed are listed too (LG, Hannstar.) The majority have data sheets that are extremely helpful. I just can't verify the accuracy of the data sheets.

http://www.displayalliance.com/research

I took mine apart and the screen was manufactured on 10/29 model No: B101AW06-V.1

I have pictures of it in the case if you need to see a closeup. I'll try and upload them Tuesday.
[G Tablet General] eppyramot:
To thank this forum i opened mine up briefly. It looks like it wont take a thicker screen then the one in there.

I found this (it is Chinese but with Google translate it makes sense). The dimensions are different than what i saw in other posts before, but seem to match my screen.

For the B101AW06 V1: 245.5x147.0x3.6

(Viewing area is 222.72x 125.28, matches my crude calculation exactly).

http://www.panelook.com/modeldetail_parameter_cn.php?id=39799

(2nd TAB).

Note also it says the viewing angle is from 6 o'clock.

I got this from another site:

6 means best viewed from below; 12 from above. So I guess that is why it looks best flipped around.
[G Tablet General] teknikk7:
VA is MVA & PVA, I would take those any day over TN.

[G Tablet General] ranjumathew:
I have an inspiron 10, and tried to swap the LCD Screen. The Dell screen is about a mm too tall. It also seemed to be about 1-2 mm thicker than the GTab screen. I am still interested in adding memory and GPS to this device. Does anyone know if there are repair places that would do the soldering for me near Austin TX?
[G Tablet General] teknikk7:
Was there anyway to make it work? Longer screws? Scraping away plastic? That you could see?

Also, how are the viewing angles? It is significantly better that the stock screen? Any vids or pics of the angles would greatly be appreciated.

Thank you

Available replacement LCD's for G-Tablet

Ok guys, I read through the entire post to get an idea of what you're looking for. From what I've seen, these panels would be of interest to the group:

B101AW06 V0-Current G-Tablet Display

B101EW05-Possible cross

LP101WH1-TLB1- Possible Cross

B101AW06 V1- Possible Cross

I looked through my system and have had recent offers on all these panels. Some are from brokers you listed on the posts, and others are from distributors we commonly buy from.

I can validate the specs and quality of the panels we buy-If you guys cant put together desired quantities, target prices and means of pay, I could bring in a lot.

Id have to double check but I believe the panels come in boxes of 10 or 20. I cant exactly tell by looking at the spec but can confirm tomorrow.

We'll also have our e-commerce sight up and running hopefully by mid Feb.-You'll be able to check inventory and available overseas offers.

We can also source controllers and ATMEL parts, whatever it might be.

I've learned a lot from this post-my job is to broker parts, so let me know how I can help.

[G Tablet General] rothnic:
One thing that is hard to come by is spec sheets for these. My current concern is buying something that is basically the same as what we have.

Could you source spec sheets for each of those so we can compare?

For example, what is the difference in the v0 and v1 in terms of viewing angle etc?
[G Tablet General] daml:
so i went and ordered this screen: http://www.nbkit.com/Wholesale/prod...n-10.1-inch-LED-1366x768-WXGA-HD__c18093.html

i will tackle the slight thicknesss when i get it. i love the resolution.

will let everyone know how this turns out.
[G Tablet General] rcgabriel:
Roth - I found specs for both V0 and V1 models of the B101AW06, and they both apeear to have the 45/45/15/35 viewing angles.

V1 specs: http://www.yslcd.com.tw/docs/product/B101AW06 V.1.pdf

V0 specs: http://lcd.eechain.com/datasheet_detail.asp?bg_key=A&sk_nub=B101AW06 V0

I think if we're going to see an improvement, it's going to be from somebody trying something a bit different, getting it to fit, and sharing their results with the forum. :)
[G Tablet General] moli13:
Chris,

First of all thanks for looking into this for us G-Tab owners. I'm the one here that found the AUO B101EW05 after weeks of looking for an excellent compatible screen only to find out it is not yet available but I'm kind of concerned because of the high resolution 1280X800 for such a small screen. I wonder if this would be an issue for us. Anyway, back to what I wanted to say. There are many members and lurkers here that would simply love to just add a screen that would increase the viewing angles to at least 50x50x50x50 or more if possible. I think that is what everyone here is concerned about. There are so many different viewing angle specs for the same models out there that I don't know who to believe.

Thanks again for your input
[G Tablet General] teknikk7:
To have something usable we are going to need to swap it with a "Non TN" panel.

MVA or PVA since IPS is not made in 10.1 just yet.
[G Tablet General] ranjumathew:
The viewing angles were significantly better. I didn't take the time to note the Inspiron's screens model or measure the viewing angles... I'm kicking myself now... I was in a rush and wanted to put everything back together before my wife came home to electronics parts lying all over the living room. I didn't consider trying to modify the casing, so I would just be speculating about trying to make it fit. The GTab's screen was significantly thinner than the Inspiron's screen. At this point, I am willing to purchase 3 screens if someone can find ones that work. Also, I would have thought that someone would have tried the GPS and memory mods by now. Anyone?
[G Tablet General] rothnic:
Well hopefully with a source release that will work, because resolution is set before you compile the kernel. Hope it works out.
[G Tablet General] TJ Anderson:
Lemcott - if you are able to confirm GPS and Chip compatibility, I'd pay you to upgrade mine! Please keep me in mind.
[G Tablet General] daml:
ok. so i fitted the screen. the viewing angles are a hell of a lot better.

pics to folllow.

i suggest everyone get one of these screens.

once i get it into 1366x768 resolution it will really shine. at the moment its 1024x600??? stretched.
[G Tablet General] thebadfrog:
Can't wait for pics.
[G Tablet General] jfholijr:
what if you can't get the proper resolution?
[G Tablet General] moli13:
Were you able to fit the frame. motherboard, battery and rear cover back on?

Also, I was concerned about the viewing angles of this panel because I saw three websites with different specs for the angles.
[G Tablet General] daml:
they are definitely better. i would say the 60 60 50 50 in the spec sheet is correct.

i managed to get the whole case back on. the screws arent done up the whole way but i will go around the case with some sort of filler and use slightly longer screws. you wont be able to notice once im done.

i am able to change the resolution. i am just waiting on the kernel source/finding a way of doing it manually.

the tegra 2 chip DOES support this resolution.
[G Tablet General] moli13:
Daml, was it you or someone else here that ordered a screen and got the wrong one? I'm ready to order the one you bought and installed.
[G Tablet General] leo653:
Hi DAML,

I was been planning on purchasing this exact same screen but from from a different vendor (blisscomputers . net), was this your first purchase from nbkit . com or did you have experience with this vendor? Also, did you have any problems connecting the 40 pin connector? since the LG's connector is a few cm left of the connector on the stock screen.

-Angel
[G Tablet General] rothnic:
What did you change to fix the resolution?
[G Tablet General] orangezero:
floatpoo was the one who was sent the incorrect lcd from what he wanted. I think he said the viewing angles were worse than the stock. I also believe these are being talked about in at least three different threads. Don't want to step on any toes, but I'm wondering if we could try to merge all the talk into one thread to avoid too much confusion?

I was hoping to buy a new screen with these features:

1) better viewing angles

2) 1366x768 resolution

3) brightness/contrast

4) lower power usage

I'm less inclined to spend the money and time if its just for one of these.

Good to know the resolution change works. I wouldn't think it would be *that* much more taxing to the video chip, would it?
[G Tablet General] rothnic:
The new line of tablets coming out after CES with Tegra 2's will run at 1366x768.
[G Tablet General] orangezero:
Yeah, we'll all look back in 6m and laugh about how accessible these higher rez screens are, hopefully. :)

quoting floatpoo from the other thread:

"LG LP101WSB-TLN1 is AWFUL"
[G Tablet General] rcgabriel:
So it looks like we really just need to be able to change the kernel bootargs to get a higher resolution, enabled, right?

Well check out this little guide to installing Froyo on a Nook Color: http://aliwaqas.info/install-android-2-2-1-froyo-on-nook-color-advanced-guide/

I was reading through this, it sort of sounds like we just need to get to wherever the bootargs are stored in the bootloader so we can tweak them to change the resolution, right? Maybe we don't actually need the kernel source to do this after all..
[G Tablet General] abstrusius:
At least in Linux, the arguments you pass to the bootloader only affect the console resolution, no? The graphical interface resoiution has to be configured inside the window manager. So if you get a decent screen, wouldn't Android set automatically the resolution according to the hardware when the UI shows up?
[G Tablet General] ncaggie1989:
I am thinking about going with one of these displays:

http://www.makershed.com/ProductDetails.asp?ProductCode=MKPQ01

I know they are expensive, but I only paid $279 for the tablet (thank you Sears :) ). I think I could have the ultimate pimped out tablet with software tweaks from the trinity of course. I will keep looking this over until my tax refund comes in.
[G Tablet General] rcgabriel:
That's what I was trying to understand - I have used Linux since the 90s (not as my primary desktop OS since college though), but I'm not an expert on Android internals.

In a standard Linux distro, yes, the X resolution is determined by the settings in your /etc/whatever X config file depending on your distro. But there's no X Window system with Android.

From Google: http://www.kandroid.org/android_pdk/display_drivers.html Looks like Android's display subsystem just uses the standard Linux framebuffer device? But I'm not sure if that's the case with the Tegra 2 build, or if there are different drivers/how they are configured, and so on.

In Linux, the framebuffer resolution is generally determined by bootargs at the time the kernel is loaded.

That's why I suspect we need to get into the bootloader and change the bootargs for the kernel to reconfigure the resolution. Of course, we could always just build a kernel with those settings hardcoded too, after we get the kernel source. :)

There are also some ways to change this stuff at runtime in theory, such as described here: http://e2e.ti.com/support/dsp/omap_applications_processors/f/447/p/73396/274441.aspx However, I'm not sure there is an fbset binary on our G Tablets, so I don't know if that's feasible.

The only other thing I dug up was the persist.tegra.dpy5 settings from build.prop and default.prop (at least, they are in both on my Vegan beta4 build). http://developer.nvidia.com/tegra/forum/setting-default-android-resolution

Those are both set to 1920x1080, which is HDMI resolution, so I'm guessing those might just control external HDMI display through the dock adapter (which would be consistent with their presence in the dev kit, which I think only uses an external display?).

Anybody else who knows more about the display subsystem in Android and specifically on the Tegra 2 platform, please feel free to chime in. :)
[G Tablet General] floatpoo:
Note: I originally posted this in a new thread, but to help consolidate discussion into one thread, I'm (re)posting it here. And effectively killing my old thread.

------------

I took apart my GTab to install a new panel. And since my GTab is in pieces right now, I thought I would share some high resolution pictures of the hardware.

I'll leave my GTab in pieces for awhile. So if you want me to take closeups of a certain component, let me know.

How will you go about getting the google apps in hdpi-tegra vs the mdpi-tegra that is used now? As far as I understand it, these are prebuilt, so how do we get around this issue? Will we have to wait until there is an hdpi-tegra build available?
[G Tablet General] rothnic:
I am hoping it is set in the ramdisk somewhere within the boot.img. the bootloader is a binary file that we don't have source for. I think the tegra2 drivers must have a setting they look at to change it. The persist lines are for the alternative outputs only from what I've seen.
[G Tablet General] floatpoo:
I wanted to see if the blank sockets on the system board were active. So I grabbed my multimeter and tested each pin to see if any delivered power. I don't know if these sockets are controlled by software, but it looks like these sockets are inactive.
[G Tablet General] rr5678:
On the front of the system board - that unused switch area labeled K1 - could that be the recovery button as found on the devkit?
[G Tablet General] floatpoo:
What is the recovery button supposed to do? And what would I "see" if I engaged it? I have a toggle switch laying around that I could solder on to see what happens.
[G Tablet General] rr5678:
That recovery button could have maybe helped me with that brick moment that killed my G Tablet - hitting one of the devkit nvflash .cabs
[G Tablet General] vsc:
My guess you will find a high side FET for each of these somewhere on the board, where indeed software needs to turn them on.

I have looked at the usual candidates for a matching footprint with respect to the area which appears to be for a GPS module, but haven't been able to find anything (e.g. U-blox, etc).
