Touch Screen Question

Who makes it? There is a possibility that the OEM of the Touchscreen makes reference drivers for it that would allow calibration in Win7 and Linux. Or that this same touchscreen is used in another PC whose drivers could be made to work.

But this of course assumes that Panasonic is not the OEM of this part...

Gork! thought they were made by Hitachi.

 

For some reason Matsua Electric Industrial comes to mind. But I think that is the name of the parent company for Panasonic.

 

Make that Matsua Mata. What's going on here? I type (matsu-hita mat-hita) and the editor changes it between post and preview. Insert s at - sign.

The company changed names in, I believe 2005, so now every time you type the old name, the new one will appear.

 

Hummm, I see one reference to the Gunze Touch Screen being used in the Panasonic. That is not much, and may well be incorrect. There is a webpage here with Linux driver info.

Is there anyone here that has had their Toughbook apart and happened to look closely that can validate this information?

Now I know that perhaps I should have put this under Gork!'s original tread on the subject, but I was thinking that if there were a non-Panasonic OEM of the Touchscreen that they might have reference drivers available for both Win7 and Linux. That said, Mods, do with this what you will.

 

Trooper...

You wicked git!:wink:

Gork -

Matsush!ta contains the char$ sh!t so the forum deletes that $tring from your post. It does that with a lot of "improper" terms. Remember, this IS a PG-rated forum.

W.T.F.E! :rolleyes2:

 

The forum nannys will delete a lot of words. The one you reference begins with s, ends with t, and refers to manure among other things.

I figured that out it didn't seem worth arguing about. Hence the insert s bit. Or as they say here in the west " no chit".

Arail I followed the Gunze trail for a bit but didn't git anywhere. Still tracking. There are several sites with Matsuchita drivers but they are a little scary... one of them has an ad for lawyers in San Francisco of all places. I hesitate to click anything there.

Thanks

Hmmmmmm... I have Fujitso drivers....

 

Ricks is correct on this. They are fujitsu. The older laptops have 4 wires the new ones are the 7 wire.

This was a question I asked ages ago in my search for a secondary source for those touchpanels that fail frequently in the CF-29s. I KNOW that you can buy commonly-sized TouchScreens on the aftermarket NEW for $75-$200 depending on size; why the ToughBook market for such parts (both new and used) should be shackled to a price scale set by the astronomical rates from Heartland is complete mystery to me.

Once we know what the generic part is we can buy newer, updated parts as well as use updated OEM drivers (Like us guys with the WACOM digitizers do) and have support for newer OSes.

gleep.

 

Well if that is the case, these drivers should be of interest...

Is the Toughbook model a 4-wire or a 7-wire?

Also, I note that Gunze offers Competitor's Replacement Panels.

 

These are five of the photos I took this evening. The second one 133XGA0301 got a couple Google hits for CF-29 and CF-74. No manufacturer name in sight.
The third picture is where the wires bend at the bottom of the display below the inverter PCB.

The fourth one is the ribbon cable at nine o'clock on the display and the TS PCB.
The fifth shot is for those interested in holes. This laptop has no antenna (WWAN) but the hole is drilled in the case and plugged with a small plastic clip.

FWIW

Nice photos Gork!

However, it is unfortunate that no where in all that tiny writing silkscreened on the circuit boards there is no manufacturer logo or name, even if it is Japanese!

Hold the presses! L5S30348P00 is a Sanyo part number for a " SANYO Gao Liang Model: L5S30348P00 Size: 13.3 screen 1024*768 Screen type: LCD" So, and remember, I have never seen one, the LCD and Touchscreen are one piece, or are we looking at the wrong thing?

Go here for the Google cache of the Chinese auction site were one was sold in the past.

In late 2008 Panasonic bought long time competitor Sanyo. The deal was finalized in late 2009.

 

Fujistu man

 

I think the LCDs are separated from the LCD by an adhesive strip. It is the failure of this adhesive strip that has been causing all the issues with the bad touchscreens and parameter errors. The issue is exacerbated by heat... The longer in the heat the worse it will be and the more prone to failure.

 

Rick, I think my CF-30 might have this issue... Do you have a guide on how to fix this? I'm afraid I may just make it worse if I go in there van dam style and rip it all apart...

 

All I can say is to call Panny... (800) LAPTOP5.... For a time they extended the warranty on this issue as they knew they blew it. But I am not sure if that campaign is still open. You MUST be the original owner of the unit for the warranty to be applied. (That's what they told me anyway!)

 

Here is what I found from as far afield as Romania. TM133XG-A03-01 Sanyo-Torisan. The search works better when you arrange the letters and numbers as above.

TM133XG is a standard definition for a common family of Sanyo-Torisan 13.3" LCD panels; I believe the TM delineates 4:3 aspect ration and 5V digital logic voltage; while the -A03 defines the chipset and related T-Con (sometimes built-in, sometimes a separate board). The last 2 digits are simply a revision number; in most cases, you can replace any LCD with one of a newer revision as a direct drop-in; occasionally it may have an additional mounting tab that needs to be removed.

Sanyo-Torisan's part numbering conventions are often used by other MFRs to reference compatible displays; I've seen Chi-Mei and Guang-Tze (Tse?) panels using the similar #s and are directly compatible.

That part # has no relation to the TouchScreen itself; that is NOT integral in the LCD. I've heard several mentions of Fujitsu as the actual TouchScreen MFR for the Toughbook line; I believe they only have 3 or 4 families of touchpanel to choose from.

Touched.

 

The company really did change its name in 2008....but I just could not resist.

 

Read my post. "I was born at night but I wasn't born last night."

M, You're on a roll here. So tell me how the things work. And when they say four wire or seven wire which wires? I really would like to know.
