Shocking discovery my Studio 17 uses an IPS panel

As you guys may know, there are many different flavors of TFT LCD display panels. MVA, IPS, TN, ASV etc. IPS panels are coveted and are what high end, digital graphics Hollywood artists use and Professional photographers use, because of their superior view angles and accurate vibrant colors, Also Apple uses IPS panels in their Cinema Displays and in the iPad. Down side is they are the most expensive.

just by coicidence, I decided to purchase a Panasonic TC-L32S1 1080p HDTV which uses a 10-bit IPS Alpha also known as IPS Pro LCD panel, because of its great view angles, and great for gaming and have no motion blur because of IPS as well as deep rich vibrant colors.

Now there is a simple way to determine what type of LCD panel you have by switching your didgital camera to Macro, and putting it righ against the laptop display take a picture then zoom in to the image on your desktop. And you can see the pixel structures all are unique to the type of LCD display panel. Basically the DNA finger prints of what makes up the pixels of your display.

No further proof is necessary, once you verify the pixel structures are identical. Feel free to test this own your own and discover what type of LCD you have, it will tell you alot of the value of your machine. And you maybe surpised at what you find.

for reference this is PVA

Hey! This post is of great value man, thanks a lot for posting.
Will try this out.

Do you happen to know any solution for this problem, since youre the best man so far knowing his display-info, would appreciate it if you could shed some light on this problem:

I don't think it's IPS, I think it's just the brightness and contrast of the RGB LED giving you the illusion it's IPS. If you had a high enough resolution pic zoomed in enough, I think it would show not to be IPS.

I could certainly be wrong, but I wouldn't be at all surprised to find that playing tricks on you.

 

keenly follow your posts Ice Cold, wishing i have the rgb-led screen, but I have the wuxga lg screen - non rgb - and this is what mine looks like close-up:

Its likely it is IPS why? because LG is the leader in IPS displays, they put IPS displays in their home HDTV's because IPS displays are better.

RGB has little in fact nothing to do withe the type of LCD panel. RGB LED is simply the light bulb, or the light source which illuminates the panel.

 

Ice Cold I agree, I was pointing out to cygy2k who mentioned it was '[possibly]the brightness and contrast of the RGB LED giving you the illusion it's IPS' whereas I have the same result as you with ccfl panel

 

right, my HDTV is IPS but CCFL back lit.

my laptop 1737 IPS but RGB LED back lit.

thats all. I am hoping DELL buys LG's 15 inch OLED Display for use in its laptops. DELL and LG seem to have a good relationship.

And I am very glad to have an LG IPS display.

 

What I'm saying is that you do NOT have an IPS display on your laptop.

 

What do you have to support your position?

 

1 - Dell would be stupid to put that pricey of a panel in this particular laptop and not advertise it to some degree as having an above average display.

2 - Your pictures show absolutely no proof to backup your claims.

3 - I don't remember seeing some sort of mandate that I show proof to state my opinion.

 

Theres one more test and I am trying to find pictures of it to demonstrate but it is an IPS panel. How do I know that? despite the pixel structure confirmation, theres one more test anyone can do at home. All that is needed is to press on the LCD display. Normal MVA PVA etc displays except IPS when pressed will color shift and distort, white turns black/blue black turns white, all kinds of reds and green color shifts are seen upon pressure touch. IPS does not do that except for some liquid crystal wobble but not color distortion. Which is why Apple selected IPS as its display of choice for the touchscreen on the iPad. Also the Touch Screen Studio 17's may also have IPS but I can only speak for my unit.

(picture mid page shows a simple, touch test that anyone can perform to distiguish IPS panels vs VA or any other type of LCD panel. only IPS will remain largely uniform, other panel types a large halo of off lighter colors will show, on IPS panels little to no color change will take place and if any will be limited to the size of the object pressing against it, DO NOT PRESS TOO HARD and possible damage your display)

Also TN panels display the signature color shifts when view at extreme angles. My unit does not colors stay natural vibrant and completly visible so TN Film can be ruled out

Very informative post.

 

@ Ice Cold

This can be settled in five minutes. Do us all a favor and download a utility like http://www.cpuid.com/pcwizard.php. In the left pane, click on Video and post the number shown after monitor type. That's the manufacturer's panel number.

 

Manufacturer: X919N€B173HW1

Product ID #: AUO149D

Studio 1747 with 1080p

 

The easiest way to prove it's IPS is to take pictures of it from various angles like here: http://forum.thinkpads.com/viewtopic.php?f=43&t=84941

 

That would be the 1920x1080 B+RG LED B173HW01 from AU Optronics.
Full specs here: http://www.auo.tw/auoDEV/print.php?sec=notebook&section_number=3&func=info&product_id=69&items_id=2

TN, 262K colors (6-bit with dithering), 140/120 viewing angles.

I'm waiting for Ice Cold to post his details but I think his LCD could be an 8-bit panel (16.7M colors). Still TN, though.

 

soooooo in English is that a good screen?? LOL I'm lovin it j/c.
