In a nutshell, I have a JAMin and a SPV M600, and the screen quality is worlds apart between them...
P

There does seem to be a difference. I have an M600 and brought a Jamin for someone else. Side by side the Jamin looks much brighter and whiter at the same brightness level - it really is noticable. In fact if I turned the brightness to full on my M600 it was about the same as half brightness on the Jamin.
I would be interested to see if there was any difference in battery consumption between the two devices at the same brightness level. Does the Jamin give you a brighter and whiter screen for free??

I can view the screen on my Jamin from extremely shallow angles, probably less than 15 degrees and it's still pretty clear. You can't really read small writing, but larger writing is fine. I'm very impressed with it.

XDA2 Backlight

Is the XDA II backlight front lit (like the XDA) or is it back-lit (like the P900)?
It's a Transflective 65K colours screen, and I believe it is even better then P900.
Not the best I've seen on a PDA, but I am sure it is REALLY good enough.

I have to dissagree with you here. XDA2 screen is the best I've seen on any PDA - ipaq 1910, 1940, 1935, 2210, 5450 and all PalmOne devices.
It has the best contrast ratio, very clear and bright even at minimal brightness settings. It suffers on direct sunlight, that's true. But again, all transflective screen do.

I thought that someone will not agree if I say "XDA2 screen is the best", hahahaha. :twisted:
By the way, I think 320x480 screen on Sony CLIE or the 640x480 screen on Sharp's LINUX PDA (C750 / 760?) will better then the one on the XDA2, because the higher resolution give me a better feeling, even if XDA2 screen has better contrast ratio (For the contrast, I believe all of them are the best, It's no need to compare which one is better) .
Anyways, it's very subjective and really depends on particular unit as well. So, I guess we just agree that screen on XDA2 is VERY GOOD.
does the xda 2 have a variable display brightness, or is it just on or off like the xda 1, not that it matters I just wondered
Yes, the XDA II has a varaible display brightness.
that should be a little bit more gentle on the battery then.

Universal -- Differences in Screen Brightness

I got my JJ a few days back. Now one of my friends has also got his JJ. I can see that his screen is more bright than the one on my JJ although both have been set to full brightness.
I am not saying that the screen on my JJ is bad but what bothers me as to why even this minor difference. His unit came with the English ROM and mine with the Arabic ROM but this should not make a difference. Do you think these are minor differences during manufacturing.
Differences during manufacturing. The only influence in screen intensity that I have been able to establish while reviewing the Universal is when the keyboard backlight switches on. The screen then reduces in brightness ever so slightly, as if the Universal would not be able to generate enough power at that moment.

It may be the difference between Sony and Samsung LCDs.
@Cr2
You mean HTC is using LCD's from Sony or Samsung and it is a question of what is installed in my Universal. Am I right?
Thanks for the reply if the above is correct it will give me a great satisfaction that at least something is not wrong with my device. As I said the screen on my device is not bad only it is not as bright as my friends
Thanks

Different TFT-panel in S100 and S110

I just recently upgraded from Qtek S100 to the S110, got the phones from Brightpoint in Sweden, and now i have the opportunity to compare the two devices. First thing i noticed was the differences in the display that no one seem to mention anywhere in forums. The S100 panel is somewhat easier to view in direct sunlight, more reflective. On the other hand, the S110 display is somewhat crisper in the matrix, it's like looking at a display with slightly smaller dot pitch. This is very clear when using a screen protetcor such as the ClearTouch. It doesn't "spread" the pixels as much producing the typical "sparkling effect" seen when using protector. I am still a bit undecided as to which one i like the most, at first i was a tad disappointed by the S110 -- that is by the display only of course!! ;-)
Anyone else had this experience on the two?
I compared my friends MDAc and my new S110 and honestly I cant see that diff you're talking about. To me the two LCDs look identical. I'm positively shocked by the speed diff caused by the extra 64MB of RAM, in some apps this make a hell of a diff.
That's strange, i suppose HTC have been using two different panels but not just on the S110, apparently, but also on the MDA's or perhaps it's just batch-specific based upon serial numbers.
Anyway, for those who might be interested, here's some more details on the two different LCD versions i've tested so far on the Magician:
1) Earlier model (?) seen on my S100
In this version of the LCD, brightness of the screen gets darker when tilting the device upwards, i.e. looking from below the device towards the LCD, and it gets brighter when looking from above. Sideways tilting the device makes the screen fade a bit. In the outdoors, this display is bright and reflective, you can read it without backlight indoors, and in direct sunlight and wearing sunglasses, the display remains quite rich in contrast and brightness.
2) The model i have in my S110
This screen has the opposite properties when tilting vertically. Looking from below the device makes the screen look brighter, less contrast. Looking from above the device makes the screen look darker, more contrast. From a right angle the screen appears to have slightly less contrast but more vivid colours, especially red tone more brilliant. Sideways the screen has a slight, very slight yellow tint, also when viewing from below. This screen is slightly less sensitive to viewing angles and it's most evident when watching movies in landscape mode, more comfortable view. In direct sunlight the screen is very dark, less reflective. Indoors it is nearly impossible to view the screen without backlight in a low-lit room. The screen image looks weird when looking through polaroid sunglasses. Slightly less visible in the car, though not a big problem. This screen looks good with a screen-protector, less internal reflection as seen on the S100 i have (screen-protector causes the display to "shimmer" a bit)
This is just my subjective opinion of course. The S110 is really awesome, i love the extra punch in speed and the ability to install all the software you want without counting bits and bytes, i upgraded because i considered staying with this model for a while. I am still a bit puzzled about the screen, starting to get used to it now. The difference is that remarkable i had to change the today-theme i had made for my S100 because it looked VERY dull on the S110!
this is absolutely true - mda compact and xda mini (both are the so called magican series) have different screens, the screen is made by different companies. you can see the difference easily especially in sunlight. i can really tell since i have both devices and can use them with identical today screen - the xda mini screen is so mutch brighter and more sharpen and also very much better to read in straight sunlight.
cheers, lutz
Sorry to say that but that a load of bull****. Any magician uses QVGA res on the exact same size so the pixel pitch is exactly the same. Why should one look "sharper" than the other. The only way this would be possible is by moving the pixels closer together (smaller pith) or using higher res. And neither is the case with any magician. It may be slightly different with sunlight use when there really are two diff LCDs but one CANNOT be sharper than the other. Its simply not possible.
nobody said anything about resolution or anything. but you must admit that e.g. a different material on the back of the screen or another way of lightening the screen may result in different sharpness. and thats the case.
cheers, lutz
Can something look sharper that actually isnt???
yes
I know, with a lot of liquor some women tend to look sharper than they really are.
Honestly, I admit that there may be a difference in performance/looks when exposed to sunlight etc but since every screen on the magician uses the exact same pixel pitch and res and size I doubt that there is really a diff to be seen other than what some people wish they can see. Otherwise you could make an LCD sharper by altering its surface. I mean you can make it blurry when pouring vaseline over the screen but make it sharper - I doubt that.
Did you ever see different LCD monitors in a row in some market? And you still say that there can't be a difference in picture quality between two monitors of the same size and resolution? Well, if you say yes, then you should have a closer look next time! Even the whole display technology varies from display to display.
PDA displays are reflektive and there are definately differences in the quality. My guess is that they built in improved panels somewhere within the production process so that newer devices (also new S100) have the better displays than the older ones.
Well with big LCDs its a big difference. They can use a lot of panel technologies (TN, MVA, IPS etc.), different anti-refectice coatings, different resolution and pixel pitch and so forth. The variation with small PDA LCDs are way more restricted.
We seem to have a misunderstanding anyway. I don't doubt that one magician could look different from another if the LCD has another coating or different backlight etc. BUT they cant be sharper since they use the same resolution and pixel pitch so that is not possible from a technological point of view. You may find one look different (maybe better) but that is a very subjective view. Besides all magicians (no matter if they are sold by O2 or Vodafone or Qtek or ...) are made by HTC, why should they use different LCD models in the exact same production line???
Ok, now I get your point. It's how you define what you mean with sharper. Sure, the resolutions stays the same, so the sharpness with regards to the resolution isn't better.
What about this guess: They asked their LCD supplier (or chose a different one) to supply them with LCDs with better reflektive behavior because the Magician isn't great under direct sunlight. So the newer panels have a stronger reflektion. I also suppose that these reflektions on the background cause the pixel to spread their light also more to the side (sorry for saying it that way, it's just a guess and I'm no pro). This would cause a pixel also to light some of its neighbours and this would cause a less sharp picture.
Just a guess.

P3600 and sunlight?

Anyone has any experience using P3600 outside in strong sunlight?
I have a Qtek 9100 (Wizard) which is USELESS outside...
Planning to upgrade yo P3600, but if screen is still lousy, well..
So, please share your experiences!
/Ampi
Every HTC phone I have encountered is worthless in direct sunlight. The only PPC I have seen that is semi-decent is the Treo 750 and that is far from perfect.
I would live to put some window tint or mirror tint on a screen protector and see if that works better.
It's really a royal pain to use it under direct sun light - combined with the fact that the dialpad lacks both visibility and tactile...
Would help if you find a shade above you or shield the phone with your body from the sunlight...
same problem with laptops
and even old monitors using crt
But in the "pdadb.net" says: Display Type:color transflective TFT.
It means that this display should reflect sunlight, more or less, but it has to.
Or HTC tells us lie ?
The Trinity is crap in sunlight and even outside on bright overcast days.
You cant even shade it outside and have to get your self inside somewhere with low light levels.
It is very much not a summer phone, and really needs to be avoided if you spend a lot of time outside and need to use the phone
Yes, the P3600 is absolutely useless in the sunshine, I think it's the only defect of Trinity.
You all want to say that other phones of HTC like P3300, P3350, P4550 - have different display and it mush, mush better ?
I wount believe - if HTC doesn't buy or make normal transflective display all of its products have same problems.

no chance also i use exim ultra protect useless...with should reduce the reflections.. no effect :-(
OK.
If we start talk about sunlight and displays - what is the best. I tested Asus 525 - it is like SE 750 (but not like Nokia 6233 or E61 - super) for ex. What else - E-ten ?
If someone knows - tell us please.
IMO all colour screen devices are rubbish in bright sunlight. By far the best device for bright sunshine is the old mono chrome device. Like the psion 5mx. Which is far better in bright sunshine than in low light. But it is a move backwards - one I doubt you will want to make!
i think that all you saying is true.... butttt one day i was really mad about the useless screen.. put it in the brighter level and now its ok!

I respect your thoughts my friend. Each person sees a different benefit from different items! The important thing is....ENJOY YOUR TRINITY!!!!!
I have tried 3 different screeen protectors and they do not make any difference to daylight.
AFAIK, there is no product available which will help - the manufacturers do all they can with regards to coatings etc to aid visibility and build these onto the display.
All the screen protectors do is ...... protect the screen from scratches.
Adding any extra cover to the screen will by definition, reduce visibility and not increase it.
OLED or OPLED displays may have better characteristics for daylight, but the current display technology is the problem.
Some HP and Fujitsu-Siemens PDAs have way better screens
Hi all!
I am the happy user of a Trinity, and I subscribe to the opinion that in sunlight, the screen is bad. Actually, even at max brightness, it is almost black, unusable.
I can testify that there are better screens though: I had an HP 6340 (PDA-phone) before the Trinity, and its screen WAS transreflective. Actually, the brighter the sun was, the more readable the screen became (not under any angle, but most of the time). Now that I donated it to a colleague, when I see it sometimes, I admire its large and beautiful screen. I also played with my boss' Fujitsu-Siemens 720 (I think), and it is also very visible. By the way, the FS's screen is also VGA, looks way better. The Trinity's screen does not even compare, especially because the tapping also requires more force on the Trinity.
It is a phone, used outside, for crying out loud! Why can't they buy from the same manufacturer as HP does?
However, beside the poor screen and the peeling of the black paint, there is no better convergence device than the Trinity, in my opinion. Oh, and the RAM could be a tad more, I might add.
I use my Trinity outdoors all the time when I golf. No complaints here. I mapped VJLumosIII it to a button to switch to max brightness instantly.

Some Questions for Those Who Have the P6500...

I am very close to purchasing a P6500 but I have some reservations... Please provide your thoughts on the following:
1. How durable is the display (i.e. does it need a screen protector and how does this look over the already-present anti-glare surface)?
2. I have heard the display is poor (whatever that means). I care more about daylight readability and, hopefully, a very dim nighttime setting than I do about color fidelity. It is more important for me to be able to see the display in sunlight and not be be blinded by it in the dark than how movies look on it. Any thoughts?
3. I have heard the external speaker audio quality is very poor. Is this true? I'm only worried about phone calls here, not music or video. Is it loud and legible enough?
4. Some sources refer to the device as "semi-ruggedized." Does the documentation mention this and if so, what are the environmental limits (water intrusion, shock, etc.) Not vitally important to me as I care well for my devices; just couious...
Any other thoughts on the device are greatly appreciated. I do not care about the smallest, lightest, or most fashionable device nor do I aspire to have an HDTV monitor in my pocket. I simply want a big screen PDA phone with all the specs this one has as long as there are no deal-breakers lurking inside.
Thanks in advance for the replies.
re. P6500 questions
I've been happy with the P6500, but the display is definitely the most disappointing thing. The brightness seems fine -- you can make it bright enough to be readable in sunlight and dim enough to not be blinding in dark. It's not great in bright sun, but I don't think I've ever used a PDA that was. The lousy thing about the screen is its low resolution and washed-out looking colors. Whenever I pull out my old Axim x51v (with its gorgeous VGA screen), the comparison with the P6500 makes me a little sad.
Hard for me to answer the questions about durability you ask, since I'm very careful with my phone and try _not_ to test its durability! The P6500 feels sturdy to me, and the shell feels solid. I always keep it in a case and use it with a screen protector. (I use the BoxWave Clear Touch anti-glare, and the P6500 looks fine through it, maybe even better than without it?) I don't think the P6500 was designed to withstand serious impacts or water. It feels sturdy and solid, but I don't see anything in the manual about it being intended to handle that sort of punishment.
The speaker quality hasn't bothered me. It's a little tinny sounding, but it's plenty loud and seems fine for phone calls, though I tend to use a headset whenever possible. I've even occasionally played music out of the speaker-- it doesn't sound great, but not really worse than I've heard music sound out of other PDA speakers.
So -- I'm happy with the phone. I sometimes wish for something as glamorous and sexy as the Touch Diamond, but wouldn't give up the quad-band GSM or the enormous memory capacity that the double SD card slots afford.

Jumping on a not so current thread by have read a review of the O2 branded version (Xda Mantle) here if any of that information helps:

1. indeed: to less resolution (VGA would be better when reading HTML mails or browsing), but I don't need a screen protector because the display is as good as my old PDA WITH anti-glare protector.
2. no probs with it. Only exception: when vavigation in car with open roof and the sun backwards - ok - no other display would manage this sun-problem.
3. When I compare my old Medion MD 40600 with the Sedna, I can say the Sedna seems about 50% louder (comparision with iGo 2006+). I had to lower the volume with the Sedna from 10 (maximum) to 7.
4. looks like rubber surface, but it is syntetics with roundes corners
Summary: all-in-one device with lots of modern features, but sometimes probs with the internal GPS (this prob would be off topic)
I hope u can understand my translated German
greetings from Germany
