Expected lifetime of Boe-Hydis IPS UXGA display on T60P

[san]

I am currently trying to decide whether I should jump ship to a new Macbook Pro or (preferably) upgrade and keep my trusty T60p UXGA with the Boe-Hydis display.
THAT display and my 10 years of genuine Thinkpad addiction is what is keeping me from upgrading to the more powerful Macbook Pro with led-backlit displays (I like OS-X too).

I have read that the T61p motherboard fit into the T60p case so with that motherboard , a T7600 upgrade and a new Hitachi 7K200 drive , this machine should be ready to deliver the goods for the next couple of years.

However, before making the investment (money+time) into such an upgrade I would like an estimate of how long the display will keep working without visible degration in color accuracy/contrast/brightness.
The machine is already 1,5 years old and it is running about 2500 hours per year on the LCD, 90% of the time on highest intensity setting.

So what is your experiences with that display , will it work for say 10.000 hours without too much degration ?

Another question ... should it visible degrade during the next year and a half , would Lenovo change it on warranty ?

Every make/model/brand of LCD has a pair of thin plastic film polarizing filters applied to each side, regardless of transistor technology, and said polarizing filters can discolor with time and environmental exposure (usually they'll yellow)...and the CCFL's reflector can discolor as well affecting accurate color reproduction.

@ san:

Very, very interesting thread... because I am currently pretty tempted to get a BOE Hydis UXGA panel to keep as a spare if my present IDTech (FlexView/IPS) UXGA display on my T42p should ever die, and cannot be brought back to life again.

But, to give you a bit of maybe-useful information in relation to what you ask about: According to the datasheet for your T60p UXGA BOE Hydis panel (HV150UX1), you may find the detailed datasheet for this panel at BOE Hydis HV150UX1 specifications. There, you will read (on page 7), that "Lamp Life" is specified to minimum 12,000 hours and typical 15,000... so using these numbers, and your daily "on-time", you may calculate the predicted lifetime - for the lamp alone. But... the polarization screen - is hardly included in the "lamp life", I'd guess?

PS: Although I of course don't intend to "hi-jack" your thread, I would be interested in hearing if you have ever had a chance to compare an IDTech UXGA FlexView/IPS panel against a BOE Hydis UXGA FlexView/FFS panel? You will perhaps want to have a look in the thread Upgrade T43 SXGA to UXGA using T60p LCD on this very topic.

Best regards,

Johan

@Johan:
Thank you very much - that was exactly the kind of information I was interested in.
I found a german company that for a reasonable price can apply a new polarizing film - so I am more concerned about the panel itself.

As for the ID tech comparison I have no idea, never saw one myself - but from what I've read the ID tech does suffer from ghosting while I can definately say that the BoeHydis does not.

I did compare the UXGA to the SXGA+ LG/phillips IPS though , and chose the UXGA because the LG/Phillips suffered from a weird "sparkling" effect that other users have reported too. For color accuracy the LG/Phillips had the edge though.
I have been *extremely* happy with my Boe Hydis, only real annoyance is the weird purple cast that deep black gets when viewed from an angle.

The LED backlit screens currently does seem to have a few issues with sudden yellowing. There are too many threads to find "the beginning of it all" but search for "macrumors led yellow".
Also, unlike what is claimed, no LED backlit notebook display offers greater chromaticity compared to CCFL, also contrast levels does not seem to be improved much (if at all, judging by manufacturer specs.)

The IDtech and Boe-hydis have about the same color chromaticity - not much difference to tell with the naked eye i'm sure.
LG-philips are not kind with lending out datasheets, but they quote a color gamut of 45% for all their laptop screens which is still in the ballpark of the Idtech and BOE-Hydis.
I can post a CIE-diagram to compare both, when i get to modify my matlab script just slightly to show legends correctly

Johan, good news.
The HV150UX1-101 doesn't contain an EEPROM, and wouldn't be compatible with the T60 series (use HV150UX-100 instead), but for T42/T43 series i am sure it will work.
Just saying, since there seems to be more HV150UX1-101 available for sale on the market than -100, so it might save you some cash

Other than that, humn, well what is the lifetime of transistors?
It's really hard to say, i'd be more worried about the chemicals used to produce transparent red, green and blue in the color filter layer fades (which is why they shouldn't be used in direct sunlight)
The CCFL can be replaced also...

funny you were in the same boat 5 years ago as i am now,
upgrading t60p vs switching to mac,

what did you decide, how did it work out?

My brand new BoeHydis UXGA IPS screens have LED-backlight ex-factory.
They have an expected life time of 20,000 Hours.
