52 and 60 inch LCD panels coming?

1944 Views 29 Replies 12 Participants Last post by  djmp
I have been following this forum for a long time and it appears to me that LCDs are going to be more versatile than plasma.

I was wondering if anyone has heard anything about Phillips coming out with a 52 LCD? I also remember reading about six months ago that Samsung was setting up two new plants in China to make 50 and 60 inch LCDs.

In a Samsung press release that I read last week Samsung said they were going to introduce a 46inch LCD and that it was made from a substrate that was twice its size.

I currently have a 24inch WIDE LCD panel for my desktop and I love it! As I understand it, my 24 inch is made from a piece of glass that can also be cut in half to make two 17 inch LCD panels (rotated).

It makes sense that Samsung would be able to make a single 63 inch LCD with a native resolution of 2560 x 1536 from the same substrate that they use for making 46 LCDs. This would be great for me because I could hang it on my living room wall and build a custom gold-leaf frame on it so that when I am not using it as a TV or computer I could use it to display digitized artwork such as a photograph or a photo of artwork.

I would also be beneficial because I would be able to watch 4x3 without worrying about plasma burn in.

I rember a year or so ago, Bill Gates said in a speech that we would be seing computer displays that are the size of an actual desktop. I wonder if this if he was refering to 50-60 inch LCDs? Has anyone else been following this and what do you think?

I hope that they indeed do make them as big as 62".

I just installed a behemoth 60" Plasma last week and boy was it a heavy beast.

I also installed 2 30" SharVision LCD pannels above it and they were so light. This is good news for one man installation if they can do it. Im not saying there going to be feather light but they have got to be lighter then the current sets available.

As of right now the biggest LCD pannel I have available are 40" from Samsung. If there anything like thier 15" model they will be awsome as well. I installled a 15" in the same plase as the above mentioned sets and it was impressive.

So, yes it looks as though the LCD industry may be the way to go for direct view television and DLP the way to go for front projection.

The guys in the CRT forum will kill me for saying this but it loosk as though the CRT is fading fast as these other products are getting better and better. ( I currently own a CRT front projector )

I hope some of the LCD panel rumors come true. The only 63" Samsung I have

heard about is apparently a plasma. They have announced new TFT LCD

panels that are 32", 40", and 46". Only the 40" is shipping at this time from

what I have heard, and no one has seen it in the US.

There are a couple of things worth noting here:

(1) The Samsung 40" LCD is the world's largest currently shipping panel. And no one I know has seen one for sale yet.

(2) The Samsung 46" LCD is the world's largest announced panel. It presumably will ship no sooner than late next year if Samsung's past pattern is any indication.

(3) The 40" panel is supposed to retail for $10K. Even if you can get it for $7K, that is 2x as much as you can buy a 42" plasma for.

(4) Heaven knows when or if a 50" or 60" LCD will ever ship and what the heck they will cost.

(5) LCDs still don't have anywhere near the contrast ratio of plasmas and just don't look as good for video.

(6) For the money you'd spend on the 40" Samsung today, even at a discount, you could buy three plasmas over the next 10 years of the same size. You could upgrade ever 3 years and throw the old panels away. You won't need to do this, of course, but you certainly could. Or you could move them to other rooms where a touch of burn in (which you can easily avoid if you wish) won't matter too much.

(7) It would be stunning if a 50" LCD was available in 2003. It will probably be out no sooner than 2004. A 60" LCD would likely not be available before 2005.

Have viewing angle issues been solved with these large LCD panels?
Have viewing angle issues been solved with these large LCD panels?


Great Question! The strange thing is that I saw a Sharp 30 inch LCD hooked up to a HD tape source. It was incredible and off-angle viewing was not an issue. When I saw the same model playing a James Bond DVD it did not look that great and the off angle viewing was not very good. How can this be explained?

Does anyone know what causes LCDs to have poor off-angle viewing?

I think somebody mentioned that LCDs don't have the same contrast ability as a plasma. I am not challenging this, but the Sharp 30LCD when playing HD looked brighter and more contrasty than all the Plasma TV sets.

The big appeal for me with having a 50 or 60 inch LCD is that when I am not using it for a computer or TV it can display a piece of art or do a slide show where the image changes every half hour. This is important for me because I hate looking at TV sets when they are turned off. The thing I hate is that the screen is just solid black. Black sucks energy. But if there is a really cool picture on the LCD that is colorful, it emits energy. Call it color therapy if you will.

By the way, thank you everybody for sharing your input.

Jake, objective contrast ratio measurements put the LCD panels well, well behind the plasma displays. I don't know what the setup was, but that may account for it.

Overall brightness, incidentally, has next to nothing to do with contrast ratio. Many LCDs look very bright due to powerful backlights, but that doesn't make the contrast ratio any better.

The one advantage of the Samsung 40" LCD is that it has a high pixel count (1280x768) compared to a similar plasma (852x480 or 1024x768). I'd be curios to see the Samsung LCD side by side with a 42" plasma. I doubt any improvement in picture quality would justify the LCD's hefty price premium.

The biggest gripe I have with current LCD displays is the pixel response time. Even on very nice >25ms displays, blurring is still readily visible on any fast moving video. I await the next generation of >16ms response time LCD panels.

I know of some one that sold it. Take the order I mean.:)

The newest LCD TV's announced by Samsung (32" and 46"), LG-Philips (42"), and

Hitachi (no size announced) are supposed to have 12msec response times. I found

a nice industry summary about a week ago and posted a link.

I agree. I hate the fact that I cannot just leave windows, winamp, whatever, on my plasmsa for hours at a time without worrying about screensavers etc. *If* LCDs had similar performace at a similar price as comparable plasma's, I would seriously consider one.
I found this press release on the web that said that the 46 inch LCD is made from a panel twice the size. Does this not mean that if you kept the panel its full size it would be 63 inches with a 2460 x 1440 resolution? It also says it has perfect 170 degree veiwing:


"Samsung Electronics Announces 46-inch TFT-LCD

Seoul, Korea, October 25 - Samsung Electronics Co., Ltd. today announced a 46-inch TFT-LCD panel that sets another milestone in the development of advanced TFT-LCD technology.

The new panel features true-motion picture quality with a short response time of 12ms, a pixel format of 1280 by 720, and a wide 16:9 aspect ratio, the company said. Samsung has applied its proprietary Patterned Vertical Alignment (PVA) technology, which delivers a 170°-viewing angle in all directions. The color saturation is 72 percent of the NTSC standard, and the contrast ratio is 800:1.

Samsung demonstrated the 46-inch sample at the ground-breaking ceremony for the TFT-LCD module line at Suzhou, China. Mr. Yoon Woo Lee, President and CEO of Samsung Electronics Device Solution Network, said "The successful development of the 46-inch TFT-LCD panel is a competitive solution for the 40-inch-and-larger TFT-LCD TV market. Following the introduction of a 40-inch TFT-LCD TV in 2001, this is another exciting moment for Samsung. "

The first 46-inch TFT-LCD sample was incubated in Samsung's fifth-generation line in Chonan, Korea. The 1100 x 1250-mm substrate facility, operated since September 2002, can fit two 46-inches panels on each substrate. Mass production of the 46-inch panel is expected to take place in the first half of 2003.

Samsung plans to display the new panel at international expositions starting with LCD/PDP International 2002, to be held in Yokohama, Japan, October 30 - November 1."

The viewing angle claims Samsung makes are not as impressive when you stand aside the display. Plasmas really hold up from the side-angle view, whereas the LCDs don't.

As for the extra pixels, so what? For video applications they are fairly irrelevant at this time.


"Giving the top position to Samsung Electronics 20 days later, LG-Philips LCD said that although Samsung Electronics opened the era for 40 inch LCD TV, LG-Philips LCD would beat Samsung Electronics in developing 50-inch LCD TV. "Currently, the company is putting efforts to develop 52-inch module to take the top position back early next year.

Samsung Electronics, for its part, has a strategy to develop 50-inch level large modules out of expectation that LG-Philips LCD would try to take back the op position with 52 inch product. Since the development of the world's largest TFT LCD has a symbolic meaning of 'the world's top', Samsung Electronics has openly said that it would not be outperformed by LG.

Thanks to the competition over large-sized TFT LCD between LG and Samsung, technological gap over large-screened products with Japanese and Taiwanese competitors is likely to be wider. What's more, the Korean TFT LCD industry, an emerging leader in 'post-memory era', is expected to enhance its international competitiveness.

Experts said that the competition between LG and Samsung over large-sized TFT LCD development would continue to increase the limit of LCD size, which then would make inroad into the PDP market and accelerate competition between LCD and PDP over the display market for large TV. "



"The movement by Sharp is also a variable. Sharp, the largest producer in the TV LCD market, the company started to build 6th-generation (1500 x 1800mm) facilities to produce TV module with target operation in early 2004. Therefore, LG and Samsung with 5th-generation production line need to come up with new strategies and tactics to maintain upper hand in the TV market before Sharp starts to operate 6t-generation production line.

I was pulling your leg. Yes, I do, but I am looking into the new 12 ms lcds.

No offense. It's my sense of humour.

In the phrase "12 m lcds" what does "12ms" stand for or mean?


There is a time constant for refreshing an LCD display, much like CRT phosphors

have a decay time. This refresh time determines whether you will see an

image "lag" as an object moves rapidly across the screen or as the camera

pans, for example. The 12ms or 12 millisecond response time corresponds

to how fast the crystals react. Earlier LCD displays had about a 25msec response

time and were often criticized for image lag. We are hoping the newer screens

will not display any noticeable lag with the faster response.

Does this help?

Jake - he is talking about response time - LCDs have traditionaly been slow to respond to changes - hence not good for gaming.

I would also like to say I do not think LCD will be the technology of the future for flat panel TVs. I do not think you can get the manufacturabilty yields to be profitable. Probably organic LED or some refinement with plasmas (that take away the burnin/out potential)
The 12ms refers to (most of the time), the average amount of time it takes for the panel to transition from white to black and then back again. The white to black is usually called the fall time, and the black to white, the rise time. Adding both of these figures together gives us the total average response time.
