LPL Substrate reference chart. Generally, each generation LCD contains approximately 80% more surface area than the generation before
The LCD equivalent of a format war is in the works

Competition between Samsung LCD and LG.Philips LCD (LPL) has never been stronger: both companies just officially declared differing next generation LCD standards.  Since LCD substrate factories are so expensive to manufacturer (usually in excess of a billion dollars), all manufacturers of LCDs typically abide by "generation" standards so that component supplies do not need to constantly change.  For example, Samsung, LG.Philips LCD and AUO 7G facilities all produce glass substrates with dimensions of 1950x2250mm.  All 6G facilities produce glass with dimensions of 1850x1500mm.

DisplayBank reports that LG.Philips LCD has declared the 8G standard to be 2160x2400mm -- the resulting substrate can be cut into exactly eight 47" LCD screens or exactly six 52" screens.  Samsung LCD has declared the official 8G standard to be 2160x2460mm, which can be cut into eight 46" LCDs or six 52" screens. 

The rift in standards agreement ultimately will hurt consumers as component manufacturers will have to manufacturer components that will work for the 47" and 46" format sizes -- or chose to support only a single format size.  Ultimately, this will lead to component cost increases.  Typically, the LG.Philips LCD has been the first to market, and thus all other LCD substrate standards were based off panel sizes set by LPL.

Way to manufacturer a meaningless story out of nothing. Congratulations.

Total impact on the end user for slightly lower economies of scale for the raw substrate? About 1/2 of one percent.

If you want general news about stuff that only effects the thechnology world in "huge" porportions don't read a site reporting these small details. Go to a differant site with this posting junk as some of us actually like hearing this stuff.

We all like hearing the "small details"-- as long as they're accurately presented. Representing this as a "format war" that will affect the consumer in any meaningful way is trash reporting, plain and simple.

If you want exciting, dramatic stories without regard to factual basis, why not read the Weekly World Report? I hear a dog time traveller is now advising world leaders on future events.

I don't know... in terms of how much "drama" happense in the LCD manufacturing world this is probably a big deal. If you're working for any of these companies this is probably a huge deal. As to representing this as a "format war" it seems like a basic article to me... with a SUBHEADING that might be missleading... the actual heading is pretty much dead on. Thank you for arguing your point via sensationalisms with the Weekly World Report, solid point made.

they're disagreeing over 60mm on one side?

It's interesting to point out the Samsung variant involves less waste of substrate material.

For 45/46" sizes. For 52" sizes the Samsung method wastes more. But I am sure there will be much fewer 52" LCD's made than 45" LCD's.

You are, of course, correct. It's not often I admit I'm wrong...cherish the moment. :)

panel size

Can't they all just make 46" and cut an extra inch off for the 45"....I know this might not to possible but it's worth mentioning since they want to have an agrument as ridiculous as this anyway.

I'm sure they can but that will add to cost too... basically what we want is a format agreement so there is no after manufacturing costs.

No kidding, it's like the whole big endian vs. little endian debate is computer science...noone cares except the assembly programmers, and noone programs in assembly anymore!

Ok if cost is going to be nearly equivalent what person wouldn't want the larger 46" screen? Of course in heavy volume the difference in cost will be minute.

Like Samsung's proposal much better. Of course the cost of equipment factors in, but my vote still stands :)

The issue is, that since the two biggest manufacturers will be buying different size sheets of glass, the glass manufacturers will not be able to hit the same economies of scale for a given part, driving the price of both the 45" and 46" LCDs up.

Same thing w/ the silicon manufacturers to provide the silicon substrate, etc...

Do away with choice?
By JarredWalton on 3/3/2006 2:40:59 AM , Rating: 3
So was this just chance, or did they go separate ways so that competition and choice would be more limited? Before, companies that only bought panels could play the spot market and look for the "Flavor of the Week". Now, it looks like if you go with 45" you're locked in, and the same with 46".

That said, What about the 23" and 24" 1920x1200 panels? Those are both from different substrates, aren't they?

I would like one of those uncut substrates for my wall please.
