LCD panel type?

Does anyone know what kind of LCD panels were used in the iMac G4 17 1.25GHz? TN, IPS, *VA?
I'm looking towards upgrading to a new machine, and just want to know what kind of panel type I'm used to now.

Hi
Thanks for the response. No, I am curious about what panel type is used; TN, S-IPS, S-PVA etc.
I purchased mine in late 2003, but the lcd panel was damaged in 2007 and defective/not used since then. I remember the panel display did not exhibit the "dirty look" of later/current generations of LCD panels coming from the antireflective coating, thats why I am curious about what panel (type/manufacturer) it is.
If I open it, I wonder if I could find any of this information. Or maybe I should call Toshiba and give the type and serial and they could look it up.
Thanks.

Some LCD panel info

Hello all,
Like quite a few people on this forum, I recently purchased a new MB 13" aluminum and have been very disappointed in the quality of the LCD panel. In particular, I feel like the viewing angle on this display is significantly worse than my old Thinkpad X41 tablet, which is going on 4 years old. So, I went in search of some technical information, which I figured I would share...
There are three main technologies for TFT (thin-film transistor, or "active matrix") LCD panels. Twisted Nematic (TN) is the most popular type of panel because it's cheap to manufacture and has very fast response times. However, image quality on the TN panels is the worst of the three technologies. In Plane Switching (IPS, S-IPS) is the best quality panel, but is expensive to manufacture and has relatively slow response times. Vertical Alignment (VA, PVA, MVA) is a mid-range technology, somewhere between the cost of TN and quality of IPS.
This site provides a very nice explanation of the pros and cons of the three technologies:
http://www.pchardwarehelp.com/guides/lcd-panel-types.php
The vast majority of displays (notebooks and desktops) use TN panels because it keeps costs down and because the fast response times are better for games and movies. This trend was probably reinforced by the explosion of LCD televisions: for TVs, good response time is critical and vertical viewing angle is totally irrelevant.
There seems to be a consensus that all three lines of MacBooks use TN panels, but possibly with different levels of quality. I could not find much information on what causes quality to vary between panels that use the same technology (i.e., why is one TN panel better than another.)
Most IPS panels go into high-end displays, such as the Apple 30" Cinema display, for applications where image quality is crucial. It turns out -- and I did not know this at the time -- my old Thinkpad X41 is one of the few notebooks ever made with an IPS panel. I suspect they chose this panel because a tablet PC must be reasonably readable from a wide variety of angles (for example, laying flat on a desk), or it's useless.
So, maybe we just have to wait for a MacBook Tablet...Jobs, are you reading this?

SZGuy, nice digest of LCD info. You had me with every point except the one about viewing angle being irrelevant on a television. How so? When a family sits distributed around a room, all are entitled to a good view of the telly.
Every TV of at least 32" or larger uses a wide viewing angle technology panel. IPS and PVA are still hugely important in television and I don't see that changing soon. In fact, it is TN that is irrelevant in the world of TV.

T500 WXGA+ LCD Panel Adjustment Challenges

Does anyone have any LCD Panel adjustment tips for a T500 with 1680x1050 screen and Intel 4500HD GPU?I am trying to make adjustments through the Intel Graphic Media Accelerator Driver Control Panel. I am running Vista Home Basic.
A number of different calibration programs such as Calibreze start by having you set the contrast to maximum. When I do this it washes out the screen so I back off on the contrast and try to proceed through the test but the result is that the color saturation is lacking. I am further frustrated by the video settings button on the same control panel. When I change the settings here it appears to have an effect only on the small test photos provided in the adjustment window. It has no effect on the display itself. I found a bunch of color management options in Vista but I have no clue as to where to begin with these. Lastly, I tried to find a user guide for but came up with nothing.Does anyone know where to find one?
I am left wondering why I didn't just buy a machine with a dedicated graphics card.

Hi Doublej,
You don't say what is your purpose in adjusting your screen. If it is to have a truly calibrated monitor for the purpose of photo editing, then I recommend that you just give up on the laptop's screen anyway, and use an external monitor. The external monitor should be of type IPS or MVA or PVA (Wikipedia / Google these if you're not familiar with them) if a flat panel, or a (gasp!) CRT. All of those options are expensive, except the untrendy CRT. Just about every laptop screen these days and most external flat panels too use TN technology, which is great for gaming (fast response time) but utter garbage for viewing angles and color accuracy. Don't believe me? Load up a color photo on your laptop, then try looking at it from slightly above center, slightly below center, left of center, and right of center. See the color and brightness shifts? How can you possibly calibrate that? (You can't -- there's no way to always look at the screen from exactly the same angle, even if you could position your head perfectly, your eyes see different parts of the screen at different angles.) A good external monitor will also give you far better contrast ratio (brightest / darkest areas).
After getting a decent monitor, it's still a good idea to calibrate it. (I've seen some monitors from Dell and Apple come pretty close without calibration, and others that were way out of calibration by default.) The X-Rite i1 Display 2 screen calibrator comes with easy-to-use calibration software for Windows and Mac. (Other calibrators may be just as good but I haven't used them so don't know.)
The FlatPanelsDK Online Monitor Test is great for a quick visual check of your screen's calibration.
One last thing: discrete graphics have NO color calibration advantage over your fine Intel integrated graphics.

IBM Thinkpad T30 lcd panel..replacement in due?

My lcd display panel is blurry (i.e. brightness level is not as expected though pressing Ctrl+Home)...
Maybe should entire unit be replaced? In this case, how to locate the correct version as (2) types, XGA and SXGA are
available..
Where can i find panel FRU number?
If you fool me once, shame on you...
If you fool me twice, shame on me!

Welcome to the forum!
A couple of things come to mind here:
a) Go into BIOS>Configuration>Display and make sure it's set on "high". Press F10 to save and exit.
b) Is the LCD slightly reddish/pinkish on initial boot? If yes, your backlight is dying and need to be replaced. Most people prefer to replace the whole LCD panel, though.
c) If your LCD is not red or pink on boot, your inverter may be on its way out. Replacing it is a cheap and easy job, and that's where I would begin.
All the FRU numbers and instructions on "how to" can be found in the HMM that can be downloaded here:

Satellite M100-165 - LCD panel reaction time

Hi.
Does anybody know where i can find information about the time reaction of my LCD panel in my M100-165?
Does anybody know what is the LCD time reaction of m100-165 ( or m100 series )?
Thx for answers :)

Hi
The M100 series was delivered with an 14.1 WXGA 200 display type LTN141W1-L03-0.
In my knowledge this display should support a response speed of 25ms.

Replacement LCD panel - good source

Who would be a good dealer for the LCD panel only? I don't want one in a housing, cost way too much.
I will be working on a white 2ghz core 2 duo. can be matte or glossy.
I'm doing this for a project & want to learn more about doing this type of work, so please don't advise sending it in.
Thanks!

I've used powerbookmedic once before, busted a key off my old powerbook one time. It showed up scratched & I was grumpy about it, wrote them a not very nice email. They did try to contact me & make it right tho, so in their defense. The broken key was in really good shape & used the suspension, which was the reason it was broke, so really, it all worked out.
I will keep them in mind, looks like with a coupon code & cheaper shipping rates, better price than ifixit right now. Thanks!
Anyone else have input please share!

Z61m: LCD panel replacement (WSXGA+ to WUXGA)

I own ThinkPad Z61m (Type 9450-HAG). Unfortunately the LCD panel does not work any more (only top third of display works).
I consider replacing of the LCD panel (WSXGA+, FRU no.: 13N7020).
Is it possible to replace the original panel with WUXGA panel - 13N7198 or 13N7178?
If it is possible, is it enough just to exchange the panels or it is also needed to replace other parts of notebook and/or upgrade BIOS or other software?
Solved!

It should work no problems. In fact, you could probably use your old inverter. CCFL backlit LCD screens use a two pin connector from the inverter to the LCD. This connector is the same accross most if not all manufacturers.
I tried replacing a 15.4" WXGA LED backlit LCD with a WXGA+ CCFL backlit LCD. Now you might ask yourself, can I convert to LED backlit LCD. While it may be possible, I don't want to say yes just yet. Anyways, what I had to do is disassemble the LCD and remove the screen. I disassembled the original WXGA LCD and replaced it with the WXGA+ LCD. Too bad it didn't work. It wasn't because I had damaged it. The LCD originally didn't work. It had an awful display. I just wanted to know if it was possible.
The conclusion is that these parts are quite interchangeable. CCFL backlit LCDs generally use the same connectors for both the backlight and display. I am not sure about LED backlit LCDs, but it would be understandable that the manufacturers maintain some kind of uniformity. After all, they produce these LCDs for all the laptop manufacturers.

Are T4X0s lcd panels a complete fail?

At first we had the "vertical band" in our displays:
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/t410s-vertical-band-in-my-LCD/td-p/245040 (12 pages)
And now, people are coming up with bright spots on their displays. Some of the users already replaced their displays before due to the "vertical band"!
http://forums.lenovo.com/t5/T4-T5-und-neuere-T-Serie/T410s-Wei%C3%9Fe-Flecken-auf-dem-Display/td-p/4... (german)
I know those T4X0s series ThinkPads are thin as hell. But they break much too often. Lenovo has to find a solution for this. A friend owns his T410s for 5 months now and it's the second time he has to carry in his ThinkPad due to display issues.
Just wondering, when the first thread with desperate T420s owners will emerge... Is this really such a hopeless situation?

My T400 has had a bright spot since about the first week, so issues might not just be with T4x0s. I haven't had a chance to ship it back yet to have it fixed (ship it as it is under 3yr warranty) as the machine is in constant use.
While my T420 was being worked on recently (on-site service) I asked the tech about display issues. He also services Sony and other models. According to the tech, he sees display problems more often in other brands of laptops. He said that it generally happens to students or other highly mobile people, and they notice it after the machine is removed from a backpack or other bag. He finds these odd as the lcd panel will be spiderwebbed or have other issues but the glass/ plastic in front of the panel will have no damage. He blames the trend of thin & floppy displays for these issues.

T60p LCD panel died - which kind do I have?

Hi,
What is the 7-digit type/model number and 7-digit product ID on the back of your laptop (so we can confirm that it is a 14.1" model)?
Reddish glow sounds like your backlight is out. If you shine a flashlight into the screen, can you read what's on the screen? If possible, hook your T60p up to an external monitor. If it displays perfectly, then more than likely your system board is fine and it's just the LCD that needs to be replaced.
Any 14.1" 4:3 standard panel from another T60, R60, T61 and a few other models will work. Some are XGA (1024x768 resolution) while others are SXGA+ (1400x1050 high resolution). If you have a T60p it likely came with SXGA+ resolution to match the more advanced ATI graphics processor.
It's best to find a used, genuine Lenovo panel, or, even better, an entire LCD assembly, which makes for an easier swap. Look for a genuine panel with a Lenovo FRU part number printed on the back. "Compatible" or generic (non-O.E.M.) panels are often of inferior quality and may not function properly once installed since the EDID chip has not been properly programmed.
Here is the Hardware Maintenance Manual for your T60p: http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-62733

Y50-70 4k lcd panel replacement - yellow issue

Hi guys,
It has been 4 months since I bought my y50 with 4k display and still no solution for the yellow issue. I tried to call support and also to send it back and change it with the full HD model without any success as I bought it from john lewis store.
I'm really disappointed about all the support system..I'm going to fix it by myself.
Does anybody know where can I get a 4k compatible LCD panel replacement online??
Thanks loads

hi marcolino86,
Thanks for being civil and sorry to hear about your trouble.
Besides the SAMSUNG, 15.6 inch, LTN156FL02-L01 screen that's being used on the Y50-70 (see page 93 of the Y50-70 HMM), the only compatible UHD (3840×2160) panel that I've found is the SHARP, 15.6 inch, LQ156D1JX01 which uses the same Embedded DisplayPort (eDP) 4 lanes signal type but I haven't seen one went with this upgrade.
- List of 15.6" 3840x2160 displays
Seing that you have the Y50-70 FHD model, you will also need to change the eDP cable to support UHD if you're planning to go for the upgrade.

Alternatively, you may also want to consider doing what others users did on their Y50 FHD model where they changed the stock TN display to an IPS display (see this thread)

Weird scratches in lcd panel (23" acd)

Well, i'm back. This 23" is the third one I got from Apple, the two previouso one's exhibited ghosting & the pink issue.
This one doesn't have these, only some backlight leaking when viewing black images fullscreen.
The thing is, the build quality on this one is below par, I think.
1 - If I tap the lcd panel itself on the right top corner, it moves about a mm. It's a little loose, and I can 'push' it inwards about 1 mm.
2 - There is 1 stuck pixel (red) in the bottom left corner, that doesn't bother me that much actually.
3 - There seem to be 2 scratches in my lcd panel. I can't describe it very good, but a picture will do the trick. Here are 2 of them. They're not stuck pixels, the shape doesn't match up right.
http://users.skynet.be/bk318948/screen4.jpg (the largest scratch)
http://users.skynet.be/bk318948/screen2.jpg (small one in the bottom)
Should I take this back again? The build quality doesn't resemble my 2500 euro I paid for it back, in july 2004.
This is my third replacement though, and I don't want to go through that process again, so either they give me a complete refund, or they compensate me in any way for this lower build quality.
Am I overreacting with this issue or not?

How to connecttwo external 19" LCD panels over DVI to MBP

Hi,
Is it possible to connect two 19" LCD panels over DVI to a MBP and run them as a single extended desktop?
I've not been able to find an answer in the many posting and I get the impression its possible, but I'm not sure. I get more doubtful when I start to figure out how to do the cabling (daisy-chain the panels, use a DVI splitter?).
Any help is greatly appreciated!
F

Do you use this set-up with multiple monitors and the extended desktop?
I ask because I followed your suggestion but at the Matrox site (http://www.matrox.com/graphics/en/cadgis/products/th2go/th2go.php) all the indications are that it only works with Windows. Even the user handbook doesn't reference Apple at all.
It sounds like a great idea, but I'd like to verify it works before spending the $300.

What's the latest Jan. 2010 spec LCD panel model #? (e.g. 9CBD, 9CA0, etc.)

Just wondering if anyone who has a 2010 assembled 13" MBP or recently warrantied MBP can confirm the latest Apple display spec model # (e.g. My MBP was built in Sept.09 and has a 9CBD panel) that is being used?
Got the dreaded light leak developing on the side and hinge edges of my MBP -- but considering that my colours/calibration are pretty much bang on for my eyes as well as the fact that I've painstakingly applied an Anti-Glare film 100% free of lint bubbles LOL -- my conundrum if the latest spec'd panels are really any better or if it's still a lottery on whether you get a good panel if replaced under warranty. The last thing I want is to go backwards in quality!
Also if you've gone through the warranty process I'm curious on whether you have any say on whether it is another 9CBD that goes in or if you can specify to them that you're only satisfied if a Jan. 2010 9CA0 (or whatever # it is) is put in?
I am planning to wait to see if Apple quietly updates the LCD panels in the MBP line at the Jan. 27 iTablet/iPhone OS4.0 event before taking it in anyways, but hopefully someone can shed some light into how Apple have been going about dealing with the light leak issues. Thanks again.

Thanks for your kind cmments matrixxzero. I agree rockykoston I will replace my keyboard eventually myself too, with all the stories here I'm terrified to hand my laptop into service, apart from not having the spare time, Idon't want it to come back scatched, damaged and/or unfixed. That doesn't augur well for Lenovo guarantees. I am fully cpable of servicing it myself but many customers aren't and shouldn't have to.
As I say the other issue is model lines. Our Chinese friends have proven they can maintain quality and innovate now but their shere manufacturing muscle means it's all too easy to have too many models and too many variants with too much crossover.
Why drop a great design like the Z710, only let down by a middling to poor Nvidia chip and introduce new 17.3" models with absolutely no maintenance covers and sealed batteries!! They should have upped the Nvidia chip (the same as the Y50) and a better WLAN card. Same with the 15.6" models - evolve the Z510 to have a case like the Z50 but the same or better components again. Similarly the Y50 should have been an evolution of the Y510 not a step down.
Lenovo has definitely gone cheap in the upper end of the consumer range, when they needn't as there are tons of cheap laptops from the brand.
Most of the reviews I came across for the Z510 described it as having very good build quality and since I changed laptops three times from the same store within my purchase period I had chance to compare closely, with at least Toshiba and Acer. I would not agree with these reviews it's OK but not great. The metal upper case fooled me a bit but it's less sturdy than a cheap i3 HP laptop it replaced. Again for around a $1000 it should be better.

MegaPC 180 - Programming LCD Panel

Hi All,
I recently built my MegaPC180 and what a lovely machine she is too!. My old machine sounded like an aircraft taking off!, this is nice and quiet with lots of mod-cons in a SFF barebone.
One thing I'd like to take advantage of is the LCD panel at the front. I know the PCAlert tool uses this, and by the looks of things it doesn't make any direct calls to the dll file which I thought may be the API for the panel.
I'm very familiar with C++ and VB and want to use the panel in several utilities I've created.
I found the msidrvif.dll file in the Program Files\MSI\Common\Bin folder. It exports the following functions...

The unfortunate thing is....I don't know the syntax of the functions, such as params, and returns.
I'm hoping someone from these forums, or from MSI technical could tell me the declarations so I can get over this hurdle?

Hi Andy,
Perhaps you have already read the posts regarding control of the LED panel. Anyway, I have done a little research myself and was able to obtain the specifications of the Bluebird VL+ controller which actually controls all the pc-off functions (and the LED panel). In theory this controller can perform more tasks than MSI used!
I also contacted Liteon Optoelectronics for the design specifications of the MSI LED panel. Unfortunately they are not allowed to release them (prohibited by MSI). However, I found the blueprints of another LED panel from Liteon with a comparable product code. I think it is likely that Liteon used the same design basics when building the MSI panel.
