LG Introduces 23-inch 240 Hz IPS LCD Panel for Monitors

LG Display, a leading innovator of TFT-LCD technology, announced today that it has launched the 23-inch 240Hz LCD for monitors (dual monitor and TV use) that refreshes at a rate of 240 frames per second to deliver clear picture quality with no ghosting effect.

The industry have been engaged in a heated race to improve the motion picture response time (MPRT), unveiling products with refresh rates of 120Hz or 240Hz which are respectively twice and four times as fast as broadcast signals (60Hz). However, the technology has mostly been applied to LCD panels for high-end TV panels that are 40-inch or larger. This is the first time that 240Hz technology was applied in a 23-inch product under mass production.

The full HD 23-inch 240Hz LCD panel was developed by combining 120Hz technology (refreshes 120 images per second) with scanning backlight technology which enables a backlight to be repeatedly turned on and off.

Boasting a refresh rate that is four times higher than regular 60Hz monitors and twice as high as 120Hz monitors, the 240Hz LCD significantly reduces motion blur to make it less strenuous on the viewer's eyes and deliver true-to-life images.

LG Display's copper bus line technology was employed for fast processing of vast amounts of image data. As a result, the product has an motion picture response time of 8ms (millisecond), akin to a large premium TV, to eliminate motion blurring for fast moving images. Moreover, the 240Hz LCD features IPS (In-Plane Switching) technology for no distortion in color or images from any viewing angle which makes products ideal for TVs.

In the past, monitors in the 20-inch range were mainly used for word processing, but expansion of the multimedia environment has extended their application to games, videos, and even second TV sets. The 23-inch 240Hz LCD panel from LG Display should allow consumers to enjoy vibrant images and picture quality they expect from a large-size TV on their monitor or a smaller, second TV.

Ha Hyun Hwoi, LG Display's VP and head of the IT business unit, noted, "This product was designed to meet expectations of consumers who are already used to superior picture quality and high motion picture response time. LG Display will continue with efforts to introduce products that deliver new value to our customers and consumers."

According to research firm DisplaySearch, the market for 26-inch and below LCD products, which are primarily for dual monitor/TV use, is expected to grow by more than 20% from 49 million units in 2009 to 60 million units in 2010.

Fire up the flux capacitor.

I wonder what the price is on these?

Sales are calculated after year-end. So that statement is perfectly fine.

Technically isn't this still only refreshing at 120hz?

But with a light going on and off behind it also at 120hz?

This is what we need! The next monitor that I'll consider, will be 24" or 26" with IPS panel (or other with good viewing angles) and 120Hz refresh rate. But it better come at 1920x1200. No 1080 flatness for me.

From the way the press release is worded, my guess would be this screen only accepts 60Hz input, just like their TV's.

:banghead: :(

Unfortunately, the market has been shifting its way to the 1080p res for the past 2 or 3 years now(even quicker nowadays). This is how companies can bank on the HD market by providing the exact pixels that full HD needs instead of the extra black borders that 1920x1200 gives.
From a business standpoint it makes perfect sense because they save more money by eliminating the extra real estate and make more money by capitalizing on the HD market. So in a sense, they double up on the potential revenue they receive. But they should also note that customers love having choices.

Anyway, this new product is certainly a welcome addition to the select few LCD monitors that have a refresh rate greater than 60. But did they really have to jump to 240hz at the drop of a hat? Why couldn't they intro into the market with a nice 120hz IPS?

240Hz? 120Hz is enough...
human eye can see one unique frame in 300, so in fact, no, its not enough.

when you add in crap like 3D tech halving the FPS on you, the more the merrier.

In regards to gaming, don't you need a rig thats capable of producing a constant 120 FPS in order to utilize the 120hz refresh rate? (I don't remember where I heard it) Or does 1 have nothing to do with the other?

that one does. but it doesnt mean you wont see a benefit at 75 or 80FPS.


even if you have Vsync off, a 60Hz screen still only gives 60 images per second - so a 120Hz screen gives you from 0 to 120 FPS actually visible.

No, that's flashing a single image for 1/300 of a second and it being recognizable due to it staying on your retina and you recognizing it.

Not the same as framerate.

the eye can see 30 fps from what I remember, correct me if im wrong though..

PLEASE lets keep two things separate : FPS and Refresh Rate.
Visible Refresh Rate issues are dependent on screen type,its specification and type of image being displayed.
Remember CRT and 60Hz ? It did flicker like hell but does the LCD flicker ? No.

GTG 2 ms, colour 5ms, these are all the same, 8ms old tech. Sure glad I paid the $400+ I did for my 24" 1920x1200 monitor. 1080p.. mines 1200p. And double-scan is just a prop. 120hz.....

That's not right either. It varies from person to person. It also depends on the medium or the game. Most can see difference to around 80, then everything seems the same after that. That's not set in stone tho.

I'm ok at anything above 45 in most games. In some, anything below 60 is choppy.

No, but they are related. If the refresh rate is 60hz, you can only see up to 60fps on the screen. It can only change the picture 60 times a second. The reason is irrelevant.

its not the same, which is why i said it that exact way.


in an FPS game, if you're sniping a target - that one frame in 300 could allow you to react faster. certainly not everyone can benefit, but i definitely believe it possible that someone at the top of their game in high action FPS, could benefit from such high refresh rates and FPS.

Yeah, that.. I can distinuguish what 60fps is, yes... but from what I read before, the eye can see just 30 fps.. its just at 60fps, a frame render is doubled and gets sandwiched in between, leaving it longer on screen, and giving the illusion of smoothness.. explains why I see 30fps in the real world, but on a screen, a smooth animation can be done.. and for crts, that light which flickers at the back.. which flashes in our eyes.. "feeding" it (the eye) with a refreshed picture.

Not sure about you guys, but for me, when a person from walks accross me, he seemed to look like 30 fps-ish

nice link and quote. Blu Ray's are only meant to be seen at 24 fps (what the movie studios shoot in) it's amazing how much more theater like it was when i got a 24p capable tv :O
Which is why 120hz & 240hz & 600hz TVs are better than 50hz & 100hz: the frame rates sync up properly.

Depending on the dude, can be between 28 to ~ 32 images/second. The thing is, that from more than 30 frames/sec, the eye(brain?) interpolates the image, and that makes it more fluid.;)
But then again, I like more than 30fps on a game. But more than 50 is a waste.....Trust me, I play since Wolfenstein 3D :D
