Hi,
When I dispay a black background color on my X1 for example the pannel screen while it is switching to a different pannel or standard pannel I see a bit of light leakage on the top 2 corners of the screen from each side. A bit white, if you understand what i mean.
Does anyone notice that?
Thanks for the info
Yep I notice it too. Probably a case of bad backlight LED placement.
This screen doesn't seem to have as good a contrast ratio (black levels) as the one on the Touch Pro.
it's rather massive. Its even visible on camera mode when you have wide-mode off.
I hate living with imperfection.
How bad is it on your device?
I have to say its not visible when other colors than black are displayed
I'm probably seeing the same thing as you are - two bright areas on the top/left edge of the display.
The light is "leaking" because the display contrast isn't high enough and the screen assembly is a bit thin.
It's something I can live with, but I do wish SE had sourced for a better display. HTC has raised the bar since Diamond and Raphael, and this one is pretty good for a Windows Mobile device, but there are tons of even better screens out there - think Japanese super-keitais.
humm.. I was trying to look for the light leakage but I can't really seem to see it.... perhaps you could post some photos of what it actually looks like?
yup, it's there
don't see any leakage on mine...
I tried one in the shop and the screen was tilting left a little bit. Also the flip was a bit loose even in closed. Any comfirmation?
I'm pretty sure all devices have the same leakage problem. Just put on a pure black screen and look for the white cones decending from the top corners.
It's because of the led's behind the screen I guess
honestly, there's very little (leakage, short of better term) if not none. If you have seen TouchPro, it leaks like crazy...
Leakage is pretty terrible, no doubt about it. Wonder if this fault is only on some handsets?

My TP don't have this at all. Virtually no leakage. Pretty much solid black even in pitch black environment. Contrast and viewing angles are excellent. One of the best if not the best screen I've seen to date. Seems like they're using 8 bit panel instead of 6 bit TN panel. The latter have terrible contrast and viewing angle as standard.
lucky if u only seen it on top corners, mine are on all corners!
i don't see any leakage... went into a pitch black room and pressed the panel button and i see no white light coming out of the corners...

then you must have a rare TP, all the TP owners in Singapore reported to have the same leakage. that's if we are talking about the same thing with regards to light leakage...
Hi,
2 days ago a friend of me and me bougt this moblie,
yesterday i gave it back to the store, cause i've seen the white
leakage on my display too, on the devise of my friend its ok.
today I'll get a new one. Hope its ok there....
Thought it was damage or so....

Maybe I'm missing the point here. Do you mind posting a screen shot of the issue so we can be on the same boat? Now you've got me curious.
I'll try and post a photo when I get home later, mine is mainly in the bottom left half of the screen and it's really noticeable and distracting when viewing something dark.
Hmmm, I've definitely noticed leakage on my xperia, in the bottom left hand corner when in landscape.
I had a Touch Pro for a few weeks before I got the xperia, and the screen on that was flawless. I might give vodafone a ring and see if I can get it replaced...
Don't forget to switch the display brightness to full to be able to observe the leakage. When I watch the Bond trailer I can definitely see the leakage on the top corners when there is a black background in the beginning. It's rather distrubing but I do believe that all devices have that in some sort of extent. I think you just have to get used to it and live with it.
Does anyone have a clue how the new screen behaves outdoor, especially under direct sun light. My current HD "sucks" on that matter, espaecially when using GPS navigation during day time .
Thanks
yeah, HD sucks under the sun lol.
indoor comparision..
The HD 2 has a light sensor which will control the backlight based on the light in the environment you in. I have seen it on a Rodium and i must say it works very nice!

If I'm not misstaken, even the Touch Diamond had that...
still doesn't answer the "question"
The Touch HD had this too but still sucks under sunlight. Even if you manually set to maximum brightness it was pretty bad under sunlight.
I thinks this is a hard question to answer till the device is in the market
Normally, it is the glass protection of a capacitive screen which gives good readability under the direct sun, while the resistive needs a plastic cover able to catch up the points of pressure filtering a lot of brightness.
In my experience (Samsung Omnia HD), the capacitive is very readable even under the sunlight, BUT, I'm not sure if the 65K colors Vs. 16M colors could affect the result.
I agree dfulgo. Although I'm not sure but I think this might really be the case.
If you have seen this video in youtube (link below) where they compared 7 different phones, even the Omnia2 AMOLED screen cannot compare to the Iphone's sunlight legibility. I think this is really mainly because of the strong reflection on the glass for the Omnia2, and not just the brightness of the screen. And the Omnia HD with capacitive screen looks better in sunlight than Omnia2.
http://www.youtube.com/watch?v=g8b5Jb_dB3M
I'm hoping this is the case, so we might have good sunlight legibility for the HD2!

I am pretty sure it's because of it being an AMOLED screen. Those always have bad sunlight readability.
I think I read somewhere, that the HD2 was ok outdoors, but I am not really sure. Well, we will know for sure when it's out.
So, "Nothing new under the sun"?
Glass Cover
If Leo have glass cover (like Iphone) outdoor on direct sun light - OK
But if have plastic cover , we must wait for next phone
I hope HTC to use glass screen !!!
Answer???
If anybody have in new HTC HD2 , lets tell us about outdoor properties!!!
if anybody can use search utility, use it
it has glass screen, under sun light it is no problem...
once againt, search utility -> 3rd from right on that brown upper panel... click on search, and add a point of your question...
Please pose a photo of the screen, at least.
Thank's
the hd2 is very good in sunlight ... de best HTC device (screen) untill now.
still the iphone is a little better.
i saw hd2 in real under the sun light. difference with iphone? NO! hd2 perfectly shows its display in any condition. just 2 differences: 1) hd2's glass is more reflecting in comparison with the iphone one, but this doesn't affect its usability 2) the tft-panel adopted in hd2 has got more contrast, black is blacker!
gsmarena
Well, what you say makes me a little bit happier, because there is a preview on gsmarena.com and they say HD2 sucks under the sunlight (though the overall preview is very positive, they say sun light legibility is poor)
I also read a post by xmoo who owns a HD2 said sunlight legibility sucked. :confused
Still no conclusive answer. I guess we need a photo comparison between iPhone, Touch HD and HD2.
mobile-review
According to some pictures from mobile-review (there is a review in russian, google translate is not 100 procent), it looks not so bad (they say it´s better than on previous HTC devices)...problem is the screen reflects too much, but it looks to me colours are not washed out
Just wondering. When the screen is off, why is it as black as the bezel around it, same on my One S, but on my Galaxy tablet and some other phones, it's grey and you can clearly see where the screen is?
I thought maybe the glass is darker, but wouldn't this screw up the contrast/colours of the screen? Or maybe the material doesn't reflect light as much, but what material is this?
It's the screen. Amoled's backlight is from the pixel itself and doesn't need any source for backlight. It's those backlights on non Amoled screens that make black look grey.
Edit...
Misread what you asked. Thought you meant when the screen is on displaying black.

You're pretty much right. Its the sheet of plastic that they use in the screen. It all depends on what type they use. It varies from screen to screen. Samsung uses AMOLED screens so they use a different type of backlight. Samsung tablets use PLS though, which is like their version of IPS. They use a lighter backlight so it looks different. I personally don't like PLS screens or bad IPS screens (like this phone). The off viewing angles are pathetic. Good IPS screens like on the Lenovo Yoga or the HTC One are great, but otherwise I prefer normal LCD. Just my opinion

Yeah but the viewing angles (in my experience) are bad if its not a high quality panel. I find the veiwing angles of this phone terrible and there's no denying it. Compared to the htc one, its horrible. I'm not trying to start a fight here, i know this phone is $300 cheaper than the htc one, but still, I prefer wide veiwng angles.
Actually my only gripe about the Nexus 4 aesthetically is that it's NOT as black as the bezel when it's off.. Sometimes it's grayish, sometimes it's actually darker (depends on the lighting). the Gnex was uniformly black when it was off (which is the one thing I loved about the design), while outdoors I can easily see the "gray" of the N4's bezel (screen if you're indoors) when the screen is off. Wish it was all black, looks much better that way.
The LCD itself is an important part of why it looks like it does, but the more important factor is that the LCD is optically bonded to the touch surface, leaving no space for light reflections, air, etc. between the touch surface and the LCD itself. In LCDs that are not so bonded you see light reflecting off the touch surface, but also light that passes through the touch surface and reflects back off the LCD surface. In an optically bonded display assembly much less light reflects off the LCD surface because they put glue or a similar substance between the touch surface and LCD so there's no air between them.
From memory it is the polarizing filter/layer(s) that dictate how dark the panel is when it is off.

AMOLED doesn't use any backlight. IPS/PLS/TN/PVA/etc. all use either CCFL or LED for backlighting, the brightness/dimness of the light source effect brightness when the display is on but not when it is off.

You said AMOLED uses a different kind of backlight, AMOLED uses no backlight so no you didn't know; and no the type of backlight isn't why they look different when the screen is off.
I received my Axon 7 on Wednesday this week. The AMOLED screen does have very good blacks and looks vibrant, but there is an issue I haven't seen discussed - I'm trying to determine if its just my phone, an issue with AMOLED in general, or perhaps a coating specific to the Axon 7:
When I view the phone directly, whites look correct (warm, natural or cool depending on the Display setting). However, turning the phone even a little off-axis, 10-20° either vertically or horizontally, introduces a very small blue shift - whites especially take on a bluish, sort of washed-out cast. It makes the colors seem much more shallow and unreliable. Can those of you who received your phones go to a WHITE or light-color screen and report if this happens for you too?
This is actually hard to identify, most people will just see something is a little "off" - to my eye, it looked like a very subtle version of a TN-panel color shift. I never have seen this on an IPS panel, though off-angles may get washed out (see Nexus 5/5X) quickly at 50-60°, they always retain their color, even if it lightens. Or, e.g., the Moto X Pure 2K IPS panel that I'm coming from has zero off-angle color shift, no wash-out, and just darkens a little even at 180°. This is my first AMOLED panel, so I'm not sure if it happens often.
If anyone can help me determine whether this is a defect or an expected limitation, that would be great.
I've noticed it on my A7 too. This is my first AMOLED phone, so I too am not sure if this is normal.
I see it also. Thanks a lot now I won't be able to insert it.
For now I will blame the screen protector that came in the screen.
Welcome to Amoled.
The cheap screen protector contributes too,
Thanks, all - I guess it's just the phone then. I actually don't have the screen protector insert applied, so I assume the "screen protector" refers to the factory glass overlay.
Does anyone know if even the new Samsung AMOLEDs exhibit this shift? I think the Axon 7 is technically a Samsung panel, but I wouldn't be surprised if Samsung kept the best AMOLED technology for themselves.
Not sure this is a dealbreaker, but it's definitely a step down from the great color-true viewing angles on the Moto X Pure. (Too bad Moto abandoned the good design the Moto X Pure had for gimmicky snap-on modules this year rather than iterating - it seems like the Axon 7 is otherwise the spiritual successor to the MXP.)

Of course Samsung keeps the top production panel for themselves... However, it's still a great panel according to colorimetry tests.
Don't notice it on my unit. Jumped from a galaxy S7 edge to the Axon 7 and the display looks exactly the same to me.
This is an area that has driven me a little crazy. I'm used to my Samsung AMOLEDs (Note 4, Note 3, S3, etc.), and they don't have any noticeable "shift", This screen is gorgeous, but it's not a top-tier Samsung panel (obviously). Still, small price to pay for a 400 dollar savings over a Note 7. I am also positive the matte screen protector isn't helping. Once my tempered glass one gets here, I will switch it out and see if it makes a difference.
Which tempered glass screen protector are you getting? I have not read one good review for any of them...yet.
As an update, I went and tried some floor model Galaxy phones at the mall, and they actually had worse off-axis blue shift. Not sure if that's because of the initial screen quality, or that it got worse over time.
Does anyone know of any AMOLED phone (specific model) that does not have any perceptible shift? Does anyone know if the shift gets worse over time?

I believe others are correct that it is the cheap screen protector. Plastics is refracting the light leaving the phone. Since blue light refracts more (the reason the sky and sea is blue). you will then to get more blue especially at certain angles.
I don't think tempered glass of the same thickness will make a significant difference but i do recommend getting a tempered glass protection because the cheap plastic one will surely be scratched very quickly. There a lot of things that will cause increased color shift, but I am not sure its a huge issue. I don't think accurate color is needed off axis. I could be wrong. I typically only look at the screen off axis when I am trying to take a odd angle picture or too lazy to move when I am in bed.
If any one does find a screen protector that distorts less please let us know.

The first thing I did was remove the screen protector, and I still notice a blue-ish shift at angles. It's minor though, and it's definitely not a dealbreaker.

AMOLED screens are typically like that. When I get on the bus and see people using their galaxies, it always looks cyan from an angle. LCD technology loses contrast at angles, whereas AMOLED has chroma shift.

Just to be clear - the color shift happens without any additional protector. Someone else used the word "protector," but I only have the bare Gorilla Glass in front of the AMOLED screen, no plastic or other layer added.
I see it as well with no screen protector on.

I never understood why phone makers use glass. Just make it plastic with a removable glass screen protector that the user can replace if broken. My GF dropped her phone, The tempered glass protector broke but protected the glass screen.
I do like that the S7 active has a plastic screen just wish all companies did this.
Hello,
I have the same issue with 5 devices I was testing. Every Axon 7 had the issue with the color shift from a red tint, to a blue tint when tilted.
Is there someone without the issue or is it really normal?

I recently got an Eonon GA8163 unit for my mazda, and for the most part its okay.
I'm really considering returning it because of the dim screen during the daytime. With sunglasses on, you can't see it, and without its still pretty dim.
Is there anything I can do to help it out?
I have everything set at max brightness, white background, but was wondering if there were any more advanced work arounds.
If there isn't anything else I can do, i'm tempted to return the unit and go with a standard brand name double din unit.
Hi there is usually a resistor or a preset resistor that you can change or adjust. But you will have to find the location of it on the board. If you have the PCB layout it would be much easier to locate it.

Thanks !!! That seems to significantly make the screen BRIGHTER. (at least it looks brighter as I look at it at night .. will see what it looks like once the sun comes up).
If it's still not bright enough, here are a few words of encouragement :-
While there is no User adjustable CONTRAST, it would seem that even at FULL Brightness, Blacks are still a full BLACK, and are not washed out and starting to become a dark gray.
This would indicate, that if the Backlight was BRIGHTER, it may still not burn through a Black section, but a white section would brighter.
So all that is needed is a BRIGHTER BACKLIGHT.
I suspect the current Backlight is running near maximum brightness, otherwise the manufacturer would set it up higher -- so what is needed is an Upgraded Backlight (and possibly associated Backlight supply).
A better backlight would cost more in production, so to keep the cost down, a manufacturer will fit a backlight with the minimum brightness (ie Cost), that they can get away with.
However, LCD displays can have potentially have very high power Backlight in them, so that they can be readily readable in BRIGHT sunlight. (if battery power is not rationed -- ie in a Smartphone). Car has a "BIG" battery, so a more power hungry BRIGHTER backlight would not be an issue on car battery life.
Next time I have the Unit "out of the car" I intend to take a look at the backlight, and research the possibolity of fitting a significantly brighter backlight. It should be possible to fit one that would be so bright, one would never want to run it at full brightness, and it would be blinding, even in direct sunlight.
Having upgraded over 200+ Industrial LCD display to brighter LED Backlights, I believe that the above might be a distinct possibility, at a reasonable cost. The only restriction might be how easy it would be for the average user, to carry out the upgrade, without damaging their unit.
If this works out, I will post some pictures and details of the upgrade.
The GS2170B is a great unit for it's price, with a very good response speed. It's only major failing I have experienced, is a sub-optimal Brightness.

Thats awesome! Have you looked into this yet/have any luck? I have a GA2170 as well which is just a bit too dim to be easily seen in daylight (night time is fine). Also, has anyone bought an anti-glare film to cover the screen? I feel that that would help immensely (mine is so shiny that any sunlight in the car at all renders it nearly unreadable).

WARNING? Long -- do not read unless you are really interested in my personal thought on this subject.
I have taken the HU apart to check out the LCD panel part. It is custom to that model, and not a readily replaceable display to a brighter panel.
So I have put modifying it on hold, and have explored some other ways to improve the appearance of the display.
(1) Tinted my Windows (they had no factory tint) .. That helped in so many other ways as well.
(2) Diagnose what was actually being reflected, which was interesting and not what I had expected.
The reflection you see when looking reasonably straight on into the display, is the reflection of what is directly perpendicularly in front of the display.
If you look at a modern car HU, they now tend to be mounted quite high up, but no longer is a shaded Tunnel/Hole.
Instead, the are mounted at an angle to point up at the inner ceiling of the car, which optimally is a dark color, and therefore is not throwing much reflective light onto the front of the Glass.
I had always incorrectly assumed, it was the direct sunlight, shining through the windows onto the panel, but this is only part of the reflection problem.
If you get a sheet of white paper, and move it around about 2 feet from the display, you should clearly see, that when you get the paper into a perpendicular position in front of the display, that the reflection from that white paper is the major cause of not being able to read the screen ,
Replace that white paper with a Mat Back sheet, and the display becomes amazingly more readable,
This is why the manufacturers now slant their units to be pointing up at the ceiling, between the drive and passenger seats.
Anti Reflective Films: I have yet to find a decent, effective, anti reflective film.
Most being sold are to help prevent scratch damage to the front glass, and if anything, are actually more reflective than the glass itself.
Manufacturers can get a pretty good anti reflective coating onto Glass (example, a good Picture frame glass, or car dashboard glass), but it must be a lot more difficult, or cost prohibitive, to get a decent anti reflective coating onto a cheap $10 screen protective film.
Since my unit is a replacment for the 2din radio in a 30 year old (Classic ?) car, and is located low in front of the gear level, and not higher up as in most modern cars, I have made compromises.
Even it it was Highly Bright & Readable, looking down at it is a major distraction of taking your eyes completely off the road, so I have concentrated now on making the unit more controllable by the addon steering wheel Buttons, and with Google Assistant control, that there is now seldom a need to even look at the unit, especially for any length of time, or to perform any complex, distracting operations.
This approach is working well, and as time goes by, I am finding I am getting far less concerned about the lower brightness display.
Also, since my Unit has Video Out, I am considering mounting a small Video screen up in my Instrument panel (Probably covering the Tach, and having a nice bright display there that I can see while still looking ahead through the windscreen. The other option is a nice bright Heads Up display, throwing the Information onto the Windscreen, just like the Air Force Fighter Pilots have in their jets !!

Thats awesome! Have you looked into this yet/have any luck? I have a GA2170 as well which is just a bit too dim to be easily seen in daylight (night time is fine). Also, has anyone bought an anti-glare film to cover the screen? I feel that that would help immensely (mine is so shiny that any sunlight in the car at all renders it nearly unreadable).

My GA2170B came with a film already on the screen (I think that was just a factory/shipping anti scratch protective film), and a separate, user installable protective film, that claimed to be anti reflective, but did not appear to do much to top reflections.
Manufacturers poor attempt to compensate for what they must realize is a "cheap sub standard brightness screen" -- but you get what you pay for.
You want something really nice and high end, be prepared to drop $1000+
I wish the glass on the Eonon was like the Glass on my 30 year old car's Instrument panel.
It has NO RELECTION at all, and when it is clean, you cannot even see that it is there. It looks like you can just reach out and physically touch the needles of the Gauges, even when there is bright sun shinning in directly onto it.
All the sun does is to make the Needles and Gauge Scale brighter !!
Thanks for the update! I guess I'll have to keep using it as I do until anything else changes. Cheers!
