Its all good, I don't take forums personally.I think forums are good for open discussion. I hope everything turns out ok with your family.
Many thanks.
Low viewing angles is a critical sign that the EVO is using something that's closer to TN technology. I'm not saying that all IPS panels are equal, I'm saying that whatever variant Apple is using, its superior than a standard tft lcd.
Standard TFT-LCD? OK - I'll grant many LCDs look completely terrible - but a _great many_ look spectacular. I'm having to take by context what you mean by _standard_ - I just don't have a reference for that word with respect to TFT LCDs.
TN displays are not common for any high end device. They tend to be limited to 18-bit color and require dithering to achieve an acceptable color range. mrspeedmaster wants to cry shenanigans by looking at a picture that mikeyandroid has moved on from, but given Mike's professional background - and the further test picture he provided that I studied myself - I conclude that the Evo display is 24-bit without dithering.
And - my hands are clean on that. I originally began with a (gentle for me) insistence that the Evo display was 16 or 18-bit and was dithering. I, too, cried foul on mikeyandroid, and even threw out my own single observable that might have supported that the Evo display was 24-bit as due to my own occluded observer bias. In the end, however, I was able to become completely convinced that he was right. (Small surprise - this sort of thing is a part of his professional life.)
As for IPS being so very superior - your posts have caused me to google to see what the latest jungle drums are beating.
I'm completely shocked.
I now find a vast support among a number of users, in light of the iP4, calling for hopes that the iPad's "crappy S-PVA" display be tossed aside in favor of the "superior" IPS technology.
Part of the proof is the poor off-axis viewing of the iPad.
Astounding.
It's my understanding that the iPad's S-PVA display is made in a fab resulting from the joint venture between Samsung and Sony. The iPad's display is EXACTLY the same species as one of Sony's high-end, Bravia line, HDTVs.
There is not a single IPS type or species that can match it for color accuracy - precisely why it's one of the HDTV darlings. It does so at the expense of viewing angle when compared to IPS.
Yet now - it's crappy according to IPS fans.
Absolutely astounding. My feeling after finding this out is best summed up by Fred Sanford's most famous line -
Hold on, Elizabeth! I'm coming!
(No - I don't own a Sony TV - but c'mon - a Bravia-equivalent display is
crappy? And, yeah - display software is involved - tell me where Apple ever farkelled on that one.)
Some IPS displays are quite good. As I've mentioned, the LG H-IPS ones (again, from their HDTV exploits) are in my opinion only among the best of that breed. Wrongepedia says that they've become the darling for pro digital photographic use and I wouldn't doubt that claim.
And, while I've simply expecting that the Apple displays are all H-IPS from LG, it seems that I may be wrong again - they could all very well be E-IPS.
Note the following article:
LG Display (LPL) 23″ e-IPS 1080p LCD Monitor Panel :: displayblog
OK, crow on the IPS species involved - yum, yum!
All that aside - please re-adjust your thinking, independent of this discussion, that any display featuring less-stelar off-axis viewing is therefore crappy and therefore TN. All TN is crappy, but not all superior LCD technologies have spectacular off-axis viewing - as evidenced by statements above.
Do I have a point?
It would have to be in response to what I think the discussion has seemed to become:
do I think that the Evo display is inferior to the iP4?
- Off-axis viewing: iP4 wins (Importance of that is completely subjective as to how much you like to share your display - some people do. Punditry can claim better security with lower viewing angles - I guess. This is a user preference and only gains value as a display quality metric for an owner's preferred use.)
- Color. For photographic color range, and therefore accuracy, I have to give it to the iP4 - mikeyandroid has proven that the root cause is gimped Android 2.2 software, at minimum. We have yet to determine if the Evo display driver is up to the job once the Android veil is lifted. For my part, I hope to be able convince others this week to let me see Buck Bunny side by side to judge H.264 playback quality.
- Resolution. The original point of this thread. On paper, the iP4 wins. However - so does the Evo. Both surpass SMPTE criteria - and I hope we can finally agree that there is a point of diminished return in dots per inch on a display, regardless of marketing claims. (Unless anyone wants to tell me that MacBook Pro looks bad in that regard (lmao) - and again, my Evo's pixel density exceeds that single metric.) Up to your nose, I've no doubt that the higher ppi density would win on fine resolution. When I start using any displays up to my nose, I'll concede the point. Don't hold your breath, though.
- Detail. iP4 may win due to superior color for given applications - but not because of uber resolution, nor because the display is IPS. It's a high-quality color display (good hardward that happens to be IPS and good software) and with displays, color comes before resolution in perceived detail, all things being equal. Both are equal at overkill per the SMPTE.
I'm not saying that the iPhone4 IPS has the finest/unique, I'm just saying that in a real world test one aspect of it, direct sunlight, it seems to perform just as well as the Super AMOLED, which according to samsung performs very well in sunlight.
I'm not saying that Apple's IPS is unique and that they did something magical to have this tech that others don't. Other phone manufacturers can have the same screen too if they wanted.
As I've said before, by and large, I'm very much a fan of Apple displays in general. I have next to me, still as clear, bright and vibrant as the day I bought it (a decade ago?), the original 15" 1024x768 Studio display as but one example. Don't remember what tech that beast used.
Our development staff primarily uses Mac displays.
So, yes, IPS when it's good, can be very good for some/many applications.
In fact - if time allows - I think I'll start by putting down the kickstand, set my Evo on the front of the MacBook Pro, and just play Buck Bunny back on both, time-sync'd as closely as possible, for a VERY subjective H.264 color quality test. My laptop isn't calibrated - but then, neither is my Evo - but it may yield some interesting observations...
Thats ok, people disagree. I work with print as well, so I'm kind of a print snob. So I may be biased towards 300dpi in thinking that if we can get displays that sharp, I'm all for it.
For mobile displays for the long haul, I expect we're in for an OLED species due to power consumption.
Unfortunate, really. The more the market supports that, the less chance we'll have of getting to
QD-LED displays. Sadly, the company that was incubated by MIT for this now seems to be retreating to just using the technology to backlight conventional LCDs - not the original point at all.
Well - hope springs eternal for blue-phase LCDs, then.
I'm not downplaying research as "mumbo jumbo", What I'm saying is that we can talk all day, but sometimes its easier to just look at real world tests. For example just holding the EVO/iPhone4 next to each other and make your own analysis.
As I have most often posted here: one test is worth a thousand expert opinions.
PS - Since you're into print - maybe you can explain something to me.
When I mentioned using the text test, I was reading
Second Variety by Phillip K. Dick. This morning, I was reading
Piper in the Woods also by PKD - both books are from Project Guttenberg. Both seem to using the same Georgia (default) font. But Second Variety has different punctuation marks and just looks cleaner.
What's up with that?
