LG announces mass production of RGB LED-lit 17.1-inch notebook displays

Seoul, Korea (Sept. 19, 2008) – LG Display Co., Ltd. [NYSE: LPL, KRX: 034220], a leading innovator of thin-film transistor liquid crystal display (TFT-LCD) technology, announced that it has begun mass production of the 17.1-inch LCD panels for Notebook PC with RGB LED backlight technology for the first time in the industry on September 16, 2008.

The RGB LED backlight technology uses LED(Light Emitting Diode) lamps that emit three primary colors of red, green and blue. The color reproduction rate of the LCD with RGB LED backlight reaches up to 105 percent [of the NTSC Gamut], offering 40 percent more colors and 30 percent better contrast ratio than conventional CCFL models. In addition, the product is also strengthened with more eco-friendly properties, such as being mercury-free. Despite the superiority of the technology, RGB LED backlight technology has been commercialized only for LCD TVs and monitors until now, due to technical difficulties in mass production.

The mass production of RGB LED backlight LCD for notebook PC is expected to pave the way to speed up the spread of notebook PCs in professional computer graphics and PC game market segments.




“This panel is capable of high-definition display with natural colors, and overcomes the previous technical limitations. LG Display will continue to develop products that not only meet our customers’ needs but also exceed their expectations” said Man-Hyo Park, LG Display’s Vice President and Head of Notebook Product Development Department.

... Nice, large screen though

 

**** , look at what americans are missing out on what is the real reason that lg/samsung don't sell notebooks here?

 

That isn't exactly news but thanks for posting anyway.

The Americans aren't missing anything, LG is a major screen manufacturer and their screens are used by almost any notebook company nowadays, that has nothing to do with the LG notebooks.



Also, Chi Mei Optoelectronics (CMO) is another screen manufacturer that has announced notebook displays with RGBLED backlighting, they even claim they are the first to do so.

Most likely, we will see those screens from other manufacturers very soon as well. The technology itself isn't new and it's been used for TVs/monitors for some time now, but it was much more expensive to produce compared to the widely used CCFL and White LED screens that can be found on many notebooks today.

Moreover, Dell, HP, Sony, etc. already announced those screens for some of their notebooks a few months ago. Besides 17", we will also see 13.3, 15.4, 16.4 and 18.4" screens with RGBLED backlighting soon...

 

Didn't know where to post this, but thought it is of interest considering LG is about 30% of the notebook LCD market and very few 17"+ screen notebooks that are available now offer RGB LED backlit screens, and if they do, they are offered at a high premium. Thankfully, RGB LED notebook LCD's are finally becoming mainstream. Where are the detailed specs?

 

The HP Elitebook 8730w and Dell Precision M6400 are the only 17" notebooks that will have optional RGBLED screens so far if that's what you're asking for.

The only one available right now is this on the 18.4" Sony AW, and that's about it.

However, I'll be more interested to know what panel technology they use. For example, the 17" "Dream Color" in the HP 8730w is supposed to be a 8-bit panel, and if it's really something better than the widely used TN panels, that will be something.

http://www.hp.com/hpinfo/newsroom/feature_stories/2008/08elite.html

And yes, they come with a price premium, the "Dream Color" in the HP will be like 400$ over the standard CCFL one.

Anyway, we will have to wait and see, since there isn't much information besides the higher color gamut, which is nice but backlighting isn't everything.

 

amen for the mobile desktop era to come!
now a 17'' laptop can have as good a lcd screen as standalone monitor.

 

UH.....Did you even read what i said? I was talking about why the LG and Samsung NOTEBOOKS aren't sold here, not anything about us missing out on the screen..that would be pretty stupid.

 

Maybe you need to actually read the article, re-read your own post and then my comment above.

The LG and especially Samsung notebooks have absolutely nothing to do with this thread which is obviously about SCREENS as I already said in my previous post.

 

We`ll see, but one can only hope.
All the standalone monitors I`ve seen or used intensively (LCDs I mean) were better than the laptop ones..

 

so? I cant make a freakin comment about there notebooks? Or do you own this thread?

 

According to Engadget, Samsung will be launching their notebooks in the US with 5 models

as far as RGB LED screens go, the Dell site lists the Precision M4400 with an rgb led option (coming soon), first one I've heard for a 15.4"

 

hm..seems like Lenovo is one step behind, the 400 nit screen is not really that good compared to those from HP and Dell.

This thread isn't about notebooks, so your comment is rather meaningless(sure you can say anything). To me that's pretty stupid.

 

I don't care what you post, I just found your post rather misleading and that's why I clarified it. That's about it.

Now there is absolutely no need to make more useless posts about nothing in particular, move on already.

 

please stay out of this Hao, i'll squash this right now it's over, done.

 

This new LG 17'' RGB LED notebook panel is 8bit (so it's not TN, and and because it's made by LG it must be IPS). I guess it's the one used in the HP 8730W and the Dell Precision M6400.

More info about the panel: http://www.lgphilips-lcd.com/homeContain/jsp/download.jsp?fileName=LG_Philips_LCD.PDF

17'' is too big for me, I hope they soon release a smaller version of this 8bit panel, maybe it's what Dell will use for their already announced (but still not available) 15'' RGB LED panel for the Precision M4400 and Latitude E6500.

 

If it is a non-TN, IPS screen, in what other notebooks can we expect it to be offered? Both the Dell M6400 and HP 8730W are too expensive as they are marketed to the corporate crowd that have a large budget.

 

It's not TN, that's sure... it could be xVA or IPS, but it's from LG so it must be IPS.

It is an expensive panel, so I guess it will remain in expensive notebooks.

 

This pdf has been there for a while, so yeah I know about it but it doesn't exactly prove anything, at least not until someone actually see this screen.

Moreover, can an IPS screen have viewing angles like 140/120 (according to the same pdf)?




Absolutely no one has used ISP panels for a while (excluding a few tablets) and now you want to believe that they are in mass production. I'm sorry but I would at least wait for some hard evidence before making conclusions about what a certain panel must or must not be.

Let's clear this up, you are asking random people around if manufacturers like Clevo and Flextronic-Arima would use a certain type displays, maybe you would have a better luck with some of the resellers, you can email or even ask some of their representatives around.

Certain Dell, HP and Sony notebooks were announced with optional RGB LED screens some time ago, so we knew that, that's about it. Sorry.

 

I am asking anybody including re-sellers, OEMS, ODMS, and NBRers to find out as much information as possible regarding this subject. Thus far there is little information other than what has been posted randomly on various NBR threads by several different posters. There appears to be a keen interest in this so anyone please share any knowledge as you find it--thanks.

 

I Googled a bit and found out that LG demonstrated their screens including the LP171WU5 on some event some time ago, and I also find this page below which claims that the panel is still TN.

http://plusd.itmedia.co.jp/pcuser/articles/0710/25/news041.html
(you can use Google to translate it)

Some other sites list it as TN as well.

Btw, we're having the same conversation in the Sony section, and a person who believed that the AW (with the 134% Adobe gamut) was IPS and he was quite excited about it, then he checked it out in person and said he was disappointed since it was a TN panel. But then again, I haven't seen it and I don't claim anything, just sharing part of the discussion there.

Also, I want to make clear that I don't mean any of links in this post as evidence or something, but it just the only information I have found so far. Otherwise, I will wait until either I see some of these screens in person or get a proper review before I claim anything...but I'm skeptical as I see no reason to be otherwise.

 

wait a minute in that chart the 4th set of numbers what is that? IS that the nits? If so then there is a huge disparity there.

 

I told you to use Google to translate it didn't I?

http://translate.google.com/transla.../25/news041.html&hl=en&ie=UTF-8&sl=auto&tl=en

It's 300 nits everywhere, there is no problem with that or anything else for that matter.

And if you're talknig about the other link, then look at the top of the chart, it's written there and there is no problem as well.

 

You are (unfortunately) right... I didn't read the whole document carefully enough (talking about excitement?), the viewing angles are too narrow for an IPS panel and if you look at the "Mobile Devices" section they even have 8bit TN panels (I didn't know it was possible, thought all TN panels were 6bit).
So this RGB LED panel could as well be TN.

It's a shame... lots of people would want a non TN panel in their notebook (even without RGB LEDs).

 

i didnt click on the link i looks at your chart and saw 200 450 200 300 i was saying the 200 nits would be low but you already clarified that.

 

And some of those "8-bit" TN "mobile devices" have exactly the same narrow viewing angles... eeh.

We were all excited when some notebooks were announced with those screens but then that excitement was gradually turning into scepticism... it was just too good to be true.

Didn't want to spoil the party, sorry.

 

Some "8 bit" panels are actually 6bit + 2 bit dither so they just call it "8bit" for marketing purposes. The giveaway sign is the low response times which is characteristic of TN panels. It used to be easy to tell which is which by looking at the colors produced in the spec sheet - 16.7mil=true 8bit, 16.2mil=6bit+2bit dither but then some makers got smart (Samsung) and even listed 6bit+2bit panels as capable of 16.7mil colors. So I guess the best way to tell now is to have the screen in front of you and run gradient checks. For most ppl it won't be a big deal esp if the dither works well unless they're heavy into photoshop.

 

There is something they call Hi-FRC.
- http://prohardver.hu/dl/rev/2007-03/1500/iccz/hi-frc.pdf

6-bit panel + Hi-FRC = 16.7M colors, not as good as a true 8-bit panel, but it still could be quite good.

The viewing angles, however, remain a big issue of the TN panels.

Case in point, the ThinkPad W700 uses a TN panel with RGB CCFL backlighting, nice, crisp, bright - 400 nits... until you see the vertical viewing angles. :shrug:
- http://www.notebookreview.com/default.asp?newsID=4638

Btw, contrary to popular belief, the IPS panels used in notebooks were 6-bit anyway.

Other than that, I dug up some specs of the last LG IPS screen and it seem that they were even so kind to mention that so that you couldn't miss it.

 

I know about the dithering/FRC and in LG's pdf some monitor panels are listed as 16.7mio and 6bit + A-FRC, that's why when I saw 16.7mio and 8bit for the LP171WU5 I immediately thought: finally a non TN notebook panel!

But after looking at the viewing angles I don't know anymore... unless LG or a notebook manufacturer clarifies this I guess we'll only know when the panel is released.

 

This comment was rather about displays that are advertised as just "16.7M" with no further details and are actually 6-bit + HI-FRC instead of true 8-bit, which may not be that big deal since those methods could be very good as I said.

Otherwise, even if "8-bit" TN panels exist, that doesn't solve the problems of TN technology...






Dreamer out.

PS: If Hell freezes over, shot me a PM... so I could polish my ski, not for another reason.

 

According to Sweta Dash of informationdisplaydotorg

Oh how I dislike the way Dell and HP meagerly offer the rgb leds on the premium products and then overcharge. It makes one wonder, do any geeks still think a mainstream company can be on the bleeding and leading edge?

In comparison, Sony's AW series is an absolute deal. $2400 for a good laptop with a good software package. 18.4" is a buzz kill though...although with a quadro/firegl gpu the Sony AW would be an excellent workstation.

When will a notebook company create a laptop based on user feedback? I mean, let the geeks here vote on a features and pricepoint matrix...
