I added a "Flexview" note to the SXGA+ and UXGA Flexview models and put the R52 15" SXGA+ display on a separate line, because it is _not_ a Flexview.

Do you think that including an article on thinkwiki on this subject (i.e. DIY LCD replacement) is a worthy cause?

Hei, thanks for the correction. Are you sure, though, about the brightness and contrast ratios? During my research it seemed to me that Flexviews have 400:1 contrast. So probably the other models should go together with the A31p.

And besides that...do you know the values for the R52? If you don't we shouldn't just assume that it's 200 and 250:1.

I'm sure about the brightness - it's 200 nits for both the Flexview and the non-Flexview on the R52, according to the Tabook. As for the constrast values, the Tabook doesn't tell them, but I looked at the sites of IDTech and LG-Philips, who manufacture the Flexview panels, and indeed it seems that you are right and the contrast is 400:1. I changed it.

P.S. I guess one could find more information about the different screens by retrieving the part numbers for the LCD panels from Lenovo's site, finding the manufacturers and looking at their technical docs, as I did with the Flexview panels. At the moment I don't have time to do it, though.

Hei,

how do you know who manufactures the panels and what model it is? Is this a broader source where we can get info for all the models from or do you just know it fro the R52?

From [http://www-3.ibm.com/pc/support/site.wss/document.do?lndocid=TPAD-FRU Thinkpad Service Parts]you can find out the manufacturer of each LCD panel for each Thinkpad model. Finding the exact panel model based on IBM's part number may be tricky, but in case of the Flexview it was easy, because the manufacturers only have one 15" SXGA+ IPS (wide viewing angles) panel that matches the characteristics of the Flexview.

P.S. Evidently, the new T60p UXGA LCD panels are manufactured by Boe-Hydis, whose 200nits UXGA panel is rated 500:1 contrast on their site, so I put T60p in a separate line.

OK, I managed to sort out one more thing. The X41T and X60s displays - X41T uses a wide-viewing angle FFS panel from Boe-Hydis. I got the manufacturer specs, and based on them the contrast ratio is 450:1. The X60s is uses an interesting technology called "Ultralight". So far I don't know any details, but it's safe to assume that it's a different display, so I put them on separate lines.

I'm thinking two things: first, we may want to split between the regular TFT displays and the Tablet PC TFT displays, seeing as the latter have additional features, like being able to write on them with a pen. Also, we should have footnotes or maybe separate entries explaining the benefits certain technologies, such as Flexview/IPS or FFS, which essentially is enhanced IPS, patented by Boe-Hydis. The fact that these selected panels are manufactured using different technology than your standard TN panel, giving them great viewing angles and better colors really makes the laptops that use them stand out, in my opinion, and maybe it deserves to be explained further.

Latest revision as of 18:08, 24 February 2006

Just to not loose the thought: we should at some point (maybe when the at the moment still quite fractured information has settled a bit) split this page into several sub pages (like the processors page). The sub pages and their hierachical link structure could/should be:

  • Displays

Also, if anyone would have pointers to reliable information about display type, brightness and contrast ratios, please share them here so we can complete the info.

manufacturer column

I think we should add a column to the table with the actual manufacturer name and model.

--Tonko 17:50, 15 February 2006 (CET)

It's a nice idea, and I thought about it. This will greatly increase the number of table entries, as often there are different types of panels used with the same basic specs. Also, it will not be easy to find certain manufacturers, and model numbers - even harder. Nonetheless, if you do add manufacturer / model columns, I'll try to fill them in as much as I can.

--Drst 18:53, 15 February 2006 (CET+1)

I splitted the page into sub pages and redesigned the tables to include the two columns as suggested.

Separate rows is not a problem. Empty table cells is more, but i think it's preferable to have a way to provide detailed and precise information where we have it.
