washed out colors

Hi,
i just got the HTC legend last night and noticed that the colors are a little washed out at anything under 40% brightness, even the gray areas of the theme are brownish and at the lowest brightness level all the the dark coolers have a brown tint.
its only ok when its at 100% brightness .
is this normal or should i renter it ?

Same here. And I remember some reviewers also complained about yellow tint on low brightness levels. So it's probably the way this display is supposed to be, unfortunately.

thanks, i would like to hear from more users to verify this .

mine is the same as well but my screen is also showing pinkinsh grey hue on certain websites. If you browse to www.htc.com you'll see that the flash banner's background have a tint of pinkness. This is the htc desire issue as well in the topic below

at 100% brightness all grey looks grey " web pages, theme, etc" but as soon as i go ~40% the brown becomes noticeable everywhere, when i hit the lowest brightness things get really ugly .

on mine only the very lowest getting looks wrong however I also own a cowon s9 and that has an amoled screen to and on the lowest brightness colors go off on that to. id say its got something to Do with amoled screens as they have no blight so lowering the brightness feeds less power to the scrwen.
or least I think thats how they work
Sent from my HTC Legend using the XDA mobile application powered by Tapatalk

this I would assume has something to do with how an amoled screen works I own other amoled devices and they all exhibit similar behavior.
as far as I know amoled has no back lights so when the brightness is lowered the power provided to the screen is diminished causing it to incorrectly display certain colors

I set the brightness at the max but the web pages are still pink (htc.com).
Sent from my HTC Legend using the XDA mobile application powered by Tapatalk

the pink hue is caused because the screens that HTC use have the process aligned in a pen and tile config. there is an extensive article about this based on the nexus one.do a Google search

I wish I could calibrate the phone's screen like how we calibrate our lcd panels.. LOL

I understood that only deisre and nexus have this type of screen ours are normal amoled

this is true, however if htc has used these types in those 2 others its a safe assumption they would use the same in the legend
having said that mine does not look pink at all so who knows

the pink is noticeable only on particular web pages and on the gmail application.
I would understand if that is a common situation or it is present only on difected phones.

Just don't go below 40% brightness. Problem solved.
By the way, the Legend has a normal RGB-subpixel layout, therefore it shouldn't have a pink hue.

Xperia's color gradients smoother than on other devices

There are always complaints on this forum about color banding on the Xperia's 65k display, so I thought that on my new Galaxy Tablet which boasts '16 million' colors in its specs this issue would not be present.
To my surprise, Xperia's color gradients are a lot smoother.
One example would be the XDA app welcome screen which is very smooth on the Xperia's screen, but shows coarse banding on the Galaxy Tab.
The dithering technique on the Xperia seems a lot more sophisticated and I came to question if Android OS is even capable of displaying over 65536 colors at all.
Any insights into the issue?

SE changed it to look better becouse normally it would should look worser with 65k and they didnt implented 16m Colors so they changed this to look better.

Samsung always fudge their numbers.
I remember buying a samsung monitor, which was the most expensive at the time, advertised as 16+ million colours and the thing done some horrible dithering - Everything had dithering on it! EVERYTHING.
The older LCD 16bit monitor it replaced had no noticeable dithering at all and gradient changes were subtle.
I've never bought a Samsuck product again.
The samsung galaxy S is also doing some weird stuff with its colours, it's blacks are fantastic but everything else is bleh!! and the pixels are about 10X bigger than the X10s.

The color from 1.6 were noticeably garbage....alot of my favorite wallpapers looked like **** with lines all over....I couldn't even use them. Then SE announced they would not be giving us 16M colors in 2.1 so I was pissed! BUT! I didn't know they were going to do something with the colors...because whatever they did they most certainly did a damn good job because the colors in 2.1 are phenominal! ALL the wallpapers I choose look AWESOME! As for Samsung....I think there super amoled screen is overated...I just sold my Galaxy S to return to the X10...the screen is really nice on the Galaxy, but like I said before the higher resolution on the X10 makes it a very VERY close match IMO.

a bit off topic....can you post a pic of your X10 next to the galaxy tab.Want to see the size comparison

Yes....dark blacks aside, the colors in the SGS are too oversaturated and a pain on the eye. Also, all the AMOLED screens have a strange greenish-blue tint to the colours - I have nticed this in all AMOLEDs, right from the Nokia N86 to the Samsung Wave to the SGS...

Got myself a NEWER Nexus One with SLCD

The first one I ever got was AMOLED which I sold and now I got another Nexus One with a SLCD. Wow, I gotta admit the SLCD is much more clearer than the AMOLED. As for screen response, I feel like it's a little faster. I am running Cyanogen 7.1 RC1 and so far so good.
Was anything else changed on the phone besides the screen? I feel like it's a nice revision from the first Nexus One.

i've always wanted to switch for an SLCD jsut because its clearer, sharper, and my theory is that the screen draws much less power and will be better for battery life for web browsing. i wonder how true that is.

How do you tell if it is AMOLED or SLCD?

Debatable. LCDs draw a constant amount no matter what is displayed. OLED only draws power for pixels lit up.
Originally it was thought that OLEDs would be much less power but in the end it is so close that it is determined by content.

If you go in slickdeals.net and search the forum for "Nexus" they have one for around $249

exactly. i'm so sick of having to watch what type of content i'm looking at. anythign white just murders my battery and i lose 1% every 2 minutes checking stocks and whatnot. an SLCD pulls a constant current no matter the content, and i feel it would be much more manageable.

Boot into the bootloader and look at the microp version: 0b15 = amoled, 0c15 = slcd

easier way to tell(from an older thread):
Install a terminal emulator and type "dmesg", then scan the results for one of the following:
samsung_oled_panel = AMOLED
sony_tft_panel = SLCD

that's quite lucky for u.
i got mine from amazon ago and just can't stand the blue tint in all the black area, especially when i use dark themes and color most of time to make it easy on my eye and save some battery. That can't be traded towards better text display for me.
sending it back today..

they say Nexus One's AMOLED isn't really WVGA...hope SLCT fixed it.

i have a SLCD, and the colour are fantastic... only the dark, is blue lol
i have comparized my slcd with a desire hd slcd, the my display have much better colour, but the black and the white, are better in the desire hd slcd

Due to pentile matrix, AMOLED effective resolution is 392x653, 2/3 of 480x800 of SLCD.
This is fixed on new SuperAMOLED panels.

I really like AMOLED but i can`t replace my SLCD with AMOLED. Not working...

New 7.7 with burn in circles

I just got the 7.7 today, and in the evening on lowest brigtness I noticed this! I googled, and this seems to be common, should I still try to bring it to a repair center? Or is this "OK" for the samoled panels?

How to test your tab.
1. Go in to a pitch black room.
2. Set brightness to the lowest value.
3. Google black images, and scroll trough them.
You should see 6 medium circles, 2 small and hundreds of black dots.

yeah i have it too, but doesnt bother me as i rarely am on fully black apps/pages

There's already a long thread about that issue here: http://forum.xda-developers.com/showthread.php?t=1463622

I don't have this problem. LIKE at ALL. My screen is pitch black with no deviation....not even a HINT of backlight.

Not a hint of backlight?
That might be because of the 7.7 doesn't have any backlighting...
My screen is absolutely fine, too. For 3 months now.

Yeah I have the same thing on mine and had it on my Note as well. Never really bothered me.

Using the 7.7 in a totally black room with brightness at minimum and viewing totally black web pages is a ridiculous situation which says nothing about the 7.7 in every day use.

It's easily visible - and really annoying - while watching videos at night... which is a very everyday-use situation for me.
Moderators, could this redundant thread be merged with the other ongoing one?

mine doesn't have these kind of circles but got lots of tiny scratches i wonder if its really a gorilla screen or cheap plastic screen

FYI Purchased a display model (ie last one, used by lots of customers for demo) Galaxy Tab 7.7 P6810 Wifi-Only in Australia (JB Hi-Fi) on 8.Jun.2012: no burn in circles or screen defects at all. I get beautiful even smooth black screen in darkness with lowest brightness setting.

How about a screen shot of a totally black web page in a totally black room?

After some more reading, I decided to keep my "faulty" tab. This is not a big deal after all. Plus there is this problem on S II, and one is complaining. I agree that it is bad that there is this problem, but now I think its minor, and the samoled panel is still gorgeous 90% of the time I use it.

I Still Can See Pixels in S4

Somehow I can still see the border of font is jaggies for example white text on dark background in xda app or keyboard. I can see red and green pixel at the border of text..
It is not that sharp.
Do you guys can see it also?
I think full hd pentile is still not enough for 5inch screen to fully unsee the pixels, maybe it should be in 4.5 inch.

No you just have super vision.... Seriously this probably the best display that you can find.

Not a single pixel watchable here! Maybe your images are really really low in graphics or you're playing Minecraft.

The pixel arrangement does cause the odd artifact to appear on fonts, yes. I sometimes see green halos on the top edges of white fonts on black if i really want to look for it.
There is also a very clear row of red sub pixels at the bottom of the display. if this is what the OP means by 'the boarder' then yep its there and nope he's not just 'seeing things'. Id post an image from my SLR which shows it very clearly but i need 10 posts to link to external websites lol.
Anyway, it's there and real. But its so small that you can't see it really unless you are looking for it. So my advice to the OP is just dont worry about it And my advice to everybody else is.....get your eyes tested :laugh:

If i look closely i can also see pixels.. i guess we'll have to wait for 600+ ppi displays.

It's just crap images, not the lack of pixels. Find a PDF document (vector graphics instead of pixels) and you won't be able to see any.

Yes, I mean there is green/red pixel around the edge of white font especially in dark background. For example in keyboard.
