TFT Technology Breakdown and Model/Panel Index

great sticky!

 

oh cool

 

thanks for the info

 

Great information! This definitely deserves the sticky.

 

Are you sure about the Samsung 930b and 940b? The viewing angles and contrast ratio seem to high to be a TN...

 

yeah, both are listed as 700:1 contrast ratio and 160/160 viewing angles, but this is Samsung's 8ms LTM190EX-L01 TN Film panel as used in a large numer of their range and in other models too (Samsung 913N, 920N, Hyundai L90D+ etc)

 

whats the difference between AS-IPS and S-IPS

 

AS-IPS is "Advanced Super In Plane Switching", but S-IPS is "Super In Plane Switching". It's just an extension of the same technology but a new generation with a new name.

 

Hate to burst the bubble, but it seems the site you linked has very little hands on and relies on other sites reviews to make its desicions. I would recommend anyone wanting to buy an LCD look around oin the [H] forums, plenty of users have posted their experience over time with hands on.
I know my reliance on the reviews I read led me to a certtain choice and after some hands on I changed it...
I can also say that there is no substitue to actually seeing the LCD in use before you buy it(if possible). Good luck to anyone looking for a new LCD!!
And as I said, read forums and Newegg User reviews and even PM users here if you want the most info possible b4 you spend your cash.

 

I'm not sure about this, but I think AS-IPS is a buzzword for a S-IPS display that has extra electronic gimmickry to boost contrast ratios based on colors present in the scene, and perhaps use pixel overcharging as well to achieve slightly better response times.

 

oh, it's very much a marketing word certainly. The panels are still based around S-IPS panel technology, and the AS-IPS terminology seems to be so far exclusively used by NEC. It might be their way of identifying their "boosted" range. LG.Philips have developed their next gen of S-IPS as well, called Enhanced S-IPS. At the end of the day, there's a lot of different names floating about. fundamentally the panels are IPS underneath

 

what about adding the Acer AL2416W and AL2423W to the monitor list?

 

Nice work a good guide for the many newbs on this forum.

 

Time to update sticky with new info.

 

I agree, this is great info I had no idea it was here but I would like to see additonal monitors listed as well as the LG l204wt

 

full panel database can be found here: http://www.tftcentral.co.uk/, but might be worth updating the sticky itself at some point too

 

According to the Egg Samsung has a new 22" widescreen LCD the SAMSUNG 225BW. It also lists it as a TN LCD. Also it seems a bunch of new 1680x1050 panels are around the corner from Acer, Sceptre (which has HDMI and a claimed 1200:1 contrast ratio!!) and all seem to be TN, but I am not sure about the Sceptre.

 

kool

 

damn it, i bought a 1907FP without reading this. The TN blows compared to my 2001FP.

 

i just get the new Gateway 22" widescreen model FPD2275W

manual states

Panel type:
22" viewable
TFT active matrix S-PVA
700:1
16.7m colors

 

I thought these were S-IPS going on S-PVA.

 

doesn't look like S-PVA to me?! spec from gateway here. 700:1 contrast ratio, 5ms response time and 160/160 viewing angles a clear indication of TN Film. Looks like the CMO TN Film panel to me. Unless there's a different spec somewhere else is there?

 

if thats the case Gateway owes me 400 bucks becouse thats what it said 1. in the manual and 2. on the spec sheet at Bestbuy AND Circuit City

 

that is what it says in the user manual, you're right. However, there's no way that spec is indicative of S-PVA. Further more, Samsung (the only manufacturer of PVA matrices) dont make a 22" S-PVA / PVA panel yet. Can you post a couple of pics of the screen from an angle, particularly looking up at the screen from below?

 

Great info! I am wanting to get a S-IPS LCD because of it's good color output, but on your list it looks like the only manufacturer that produces them is Dell. With the exception of that one NEC (which I couldn't even find when I looked it up on Froogle).

 

there are far more S-IPS based screens than those just listed on the first post. Check out http://www.tftcentral.co.uk/ and put in S-IPS in the panel search (choose "panel" drop down) and you can see them all! plenty to choose from. The NEC LCD20WGX2 is quite widely available, certainly in UK/Europe/US

 

I just took apart a busted Hyundai L90D (NOT a "+" version) and it has a Samsung LTM190E1-L01 TFT panel inside.

Samsung's datasheet states this is a PVA panel.

 

Can't find much technical info on Planar TFT's

The PL1910M seems to be MVA.

i just got a DELL 2007WFP how do i know if its PVA or S-IPS ??

 

Go here:
http://www.tftcentral.co.uk/articles/dell_panel_lottery.htm
That will tell you how to check.

Good luck!

 

edit: nm.

 

Here's a screentest page that I made for testing flat panels.

It tests for stuck on or stuck off pixels or subpixels.

http://www.masterofeverything.com/screentest.asp?full=y&color=ffffff

go to that page, hit F11 (full screen)
then turn off the status bar and make the top tool bar Auto Hide

 

one odd thing is that it makes it sounds like S-PVA is better than P-MVA due to the way it words it.

i had kind of figured that P-MVA edged it out though.

 

wonkman, would you be able to update with acer 24-26" models? I'm very interested. Thanks!

Interesing post. I'd be very interested in seeing some hard numbers to compare the performance of these different panels types in different domains.

 

I stumbled upon this informative article written about LCD monitors. Some of it was a little confusing as it detail enriched for more advanced LCD enthusiasts. The article breaks down Response times, contrast ratios, specified, actual and dynamic, color reproduction etc. I just bought a Samsung 226BW(a) and want to learn more of the in's and out's of this thing.

I was wondering, if MVA / P-MVA / PVA / S-PVA are decent enough to play a fast game like maybe... Ninja Gaiden Sigma or something fast pace? Or would it have noticable ghosting... cuz I think usually those types are around 6+ gtg ms. And I'm not very knowledgable on these things.

 

the latest generation of P-MVA panels (8ms G2G) and PVA / S-PVA (6ms G2G) panels are considered pretty good, not quite as responsive in practice as the fastest TN Film or S-IPS models, but still well regarded.

 

I know people above said this already, but thanks again for posting this information. There's so much crap out there that it's great to have it all in this one place (and from a trusted source). [H] is awesome.

 

Good thread,but when is it going to be updated with newer models and panel stuff ?
