Information thread :Asus screens

Hi! I create this thread for people who want to know the specs of their lcd panels. I search and found 2 other threads about this but very incomplete.

Please dont put things like "My IPS screen is great...and the view angles are great...", This is a infothread, so go more specific. Like "... I have a s-ips, with 160h/150v view angles and a dot pich of 0.22...".

My v6v panel is quite good for me but corse dont compare it to a ips or a p-mva.
I'm not sure but is a SXGA+ Tn film type panel, with very low view angles, maybe 100/90 (i think its better), not a very contrast ratio, 500:1 maybe less, and the dot pich is great, 0.21mm, response time is maybe about 20ms mad: )

If anybody can tell me more about my and all the other screens in asus notebooks, and discus about then, this will be a very interessing and educational topic.

For the info I copy paste this from a forum, i dont remenber the name, but maybe this will be helpfull.

"TN film (Twisted Nematic)

- low manufacturing/retail costs
- restrictive viewing angles
- fast pixel response times
- dead pixels display white. Stuck pixels display RGB colors
- lower contrast levels means blacks are not as dark as VA based panels
- lower color reproduction

IPS (In Plane Switching)

- improved viewing angles over TN
- very good color reproduction
- slower pixel response times than TN
- dead pixels display black
- lower contrast levels means blacks are not as dark as VA based panels

Super-IPS (S-IPS)

- same as IPS except ...
- likely best color reproduction of all TFT
- less expensive to produce than IPS
- improved pixel response


VA (Vertical Alignment) Technologies

MVA (Multidomain Vertical Alignment)

- compromise between TN and IPS technologies
- superior color reproduction over TN but not as good as IPS
- very good viewing angles but less than IPS
- higher contrast than TN or S-IPS means very good blacks
- dead pixels are black
- slower pixel response than TN or IPS
- details can be lost when directly viewing dark areas

Premium-MVA (P-MVA)

- same as MVA except ...
- "overdrive" technology increases pixel response but still slower than TN
- may have slightly degraded color reproduction due to "overdrive" process

PVA (Patterned VA)

- same as MVA except ...
- larger viewing angles
- higher contrast levels means darkest blacks

Super-PVA (S-PVA)

- same as PVA except ...
- “Magic Speed” (the Samsung equivalent to Overdrive) improves pixel response
- slightly improved color reproduction
- slightly improved viewing angles



Purchasing Considerations

TN Gamers
Considered a "gamers" panel due to it's fast pixel response times which reduces trailing images know as "ghosting". However, this advantage has been reduced by new technologies to accelerate pixel response times in other panel types. Colors and contrast tend to be weak and blacks are not truly dark. Viewing angles are significantly limited. However, monitors based on this technology tend to be inexpensive.

IPS / S-IPS Graphics Work or Web Browsing
Considered to have the best color reproduction of all panel types, these panels are well suited for graphics work or web browsing. Pixel response time is also good but slower than the TN "gamers" panel. Contast and blacks are also less dark than VA panels but viewing angles are excellent.

MVA / P-MVA / PVA / S-PVA Compromise/combination for All-Around Use
These panels are a compromise between the fast pixel response times of the TN panel and the excellent color reproduction of the IPS panels. Contrast and blacks are best of all the panel types. Viewing angles are almost similar but slightly inferior to IPS. These details will only matter if you look for them, for average users like myself these are the best IMO."


Thx and lets learn something

I found this sites, maybe u found ur own here...

http://www.samsung.com/Products/TFTLCD/common/product_list.aspx?family_cd=LCD02

http://www.screentekinc.com/laptops-lcd-screens.shtml (crap, dont tell anything...)

http://www.auo.com/auoDEV/products.php?sec=notebook&func=items&items_id=2 (maybe this one is less important)

 

Ahhh... You copy and paste this from hardforum and I don't think it applies to Laptops LCDs

 

Laptop LCDs are the same tech so it all still applies. AFAIK most laptop screens are TN, which is why most have crappy viewing angles.

My Z70Va came with a Samsung LTN154P1, I had the screen replaced so I'm not sure my current LCD is the same model. All the technical specs in that link.

 

Humm... im not sure too but i think that we can call the same names.... i think the tecnologies are the same. If u can prove it, post it plz.
thx

 

Great panel lazybum131, a friend of mine have a M6va (z70va) and i love the screen.
Yeah like u said, most of all are Tn film panels, only the very best's have ips or other high end tec...

Ps: I didn't know the response time is affected about ambient temps... "RESPONSE TIME(ms at 25 °C)" (in samsung site). After all im learning

 

This is great info...
So far I think I found that
V6V = IPS
V6J = TN
W3J = TN

Is there a source where I can find out for sure what each Asus model display is?

Also, from the initial post, it states that Super-IPS is a bit better for color reproduction and less expensive to produce. If that is the case, why would a manufacturer use regular IPS? Any negatives of super-ips compared to regular IPS?

Finally, if someone knows the IPS & Super-IPS screens among the Asus line, I think it would be helpful to me and others to know.
