eIPS and cPVA :)
- Thread starter Biges
- Start date
eIPS is Enhanced IPS
cPVA is prolly Color PVA since the color gamut is much higher is what I am thinking on the top of my head
We need to see the new crop of IPS in a head to head with cPVA and we need models with 120 hertz on both with tweaked displays, not barebones cheap stuff.
If this is done then maybe I can finally switch from a CRT to LCD technology and between PVA vs IPS I don't know which one will be better as of yet.

Well, comparing my NEC 2690 (H-IPS A-TW) with Dell 2209WA (eIPS) does not show the latter as being "enhanced"But if someone manages to make 24" sRGB eIPS monitor for a price let's say <400 euro, that would be something.
LG W2420P and W2220P if they ever see the light of day? One can hope so.
The eIPS is enhanced Inline plane switching.
Super-IPS S-IPS 2001 LG.Philips remain as one of the main manufacturers of panels based on Hitachi Super-IPS.
Advanced Super-IPS AS-IPS 2005 Increased contrast ratio with better color gamut.
Horizontal IPS H-IPS 2007 Improves contrast ratio by twisting electrode plane layout. H-IPS is used in the NEC LCD2490WUXi and LCD2690WUXi, Mitsubishi RDT261W, HP LP2475w, Planar PX2611W,[5] and Apple's newest Aluminum 24" iMac. H-IPS up close.
Introduces an optional Advanced True White (A-TW) polarizing film from NEC, which results in a TW (True White) color to make white look more natural. This is used in professional/photography LCDs. One such monitor using this technology is the NEC LCD2690WUXi.
Enhanced IPS E-IPS 2009 A low-cost AS-IPS display with lowered aperture ratio to increased transmittance, resulting in some off-angle glowing and, both, lower color gamut and contrast ratio.
I hope this explains it. As far as cPVA from Samsung, there has been little written on it and in fact the Samsung model with it in 23" will be arriving in July.
eIPS is not as good as H-IPS which is the best technology. The LG W2220P is said to be an H-IPS based monitor and has more features and color correction features and the like. It however lacks the pivot feature.
The Samsung 23" with cPVA is not released yet and as such no reviews.
The only 2 monitors on the radar scren are the F2380 from Samsung and W2220P from LG that I see are worthy contenders which need to be reviewed. I am not aware of anything else which may qualify as being a quality performance monitor.
Dell 2209WA is great monitor for its price point but not good enough.

There is a preview of Samsung F2380 at it168.com : http://translate.google.com/transla...fficial&hs=PIP&sa=G&rurl=translate.google.com
The site also have the preview of Dell 2209WA : http://74.125.79.132/translate_c?hl...le.com&usg=ALkJrhi6WVbZsAyILjLkRLsHlw4WhiuqjA
So you can compare numbers....

I don't know where people are getting the idea that e-IPS is not as good as H-IPS when it's actually an improved version. NEC is calling it eH-IPS. The HP LP2475w is actually e-IPS. The monitors with e-IPS panels can go down lower in brightness and have slightly better contrast than H-IPS monitors. Other than that, e-IPS is identical to H-IPS. All IPS panels without the A-TW filter have an off-angle glow, and the gamut has to do with the backlighting, not the panel type.
Meanwhile, I think cPVA is circular PVA, which is also improved technology, not a crappy version of S-PVA. Supposedly, cPVA uses circularly-polarized light to greatly improve contrast, response times, and reflectivity at an angle.

When e-IPS was only a hype there were multiple sources (I don't know how reliable though) that said that e-IPS is a "detuned" S-IPS panel. What that really meant was under debate but all sources were at least giving the impression that e-IPS won't bring any real benefits compared to S-IPS - except for a better price.
This only gets amplified with the fact that the only(?) e-IPS monitor on the market is a 22" (a size thats dominated by cheap TN displays) and that it's cheap (compared to S-IPS).
I haven't kept myself up to date since I'm not interested in 22"/23" monitors but searching for e-IPS on the internet have never given me anything different from what I wrote above (a cheaper, detuned S-IPS panel), I've never seen anyone claim it to be an enhancement (eventhough the Dell 22" e-IPS have gotten great reviews).
cPVA is indeed circular PVA. Going from those images, it looks like the quality of cPVA is going to be vastly superior to existing PVA technology.
The question is will cPVA blow away IPS with its clarity? If those images are correct in that patent, then the cPVA ones could very well be the ones to get.
Samsung F2380 is cPVA and will be out in July.
Will wait for the next crop of models and when I see something I like, I'll bite down and buy it.

You just quoted wikipedia. How come?
I put that accuracy disputed tag there months ago, and frankly parts of that page should be blanked.
TFT publications are fun, aren't they?ToastyX said:

That was just one source with a bunch of other sources repeating it: http://www.displayblog.com/2009/01/28/lg-display-lpl-23-e-ips-1080p-lcd-monitor-panel/brumwald said:
That same source later claimed it's cheaper because the aperture ratio was improved to let more light through, so less CCFL lamps are needed: http://www.displayblog.com/2009/02/13/lg-display-e-ips-lcd-panel-update-2/

To my mind the most reasonable description of e-IPS comes from the lgphilips-lcd website.
Assuming this tidbit is related to IPS.
