does red colored scheme in wp7 uses less power?

Mango comes with default red. Anyone can verify??

Hmm, what a strange assumption?!.. If it was a black on black scheme, I can agree

Black on Black uses more power on "regular" LCD Displays. AFAIK, only AMOLED screens use less power when displaying a black screen compared to white.

red is a low intensity colour right?
used in military for night operations..

I assume the change to red as default color scheme comes from the new, square windows phone logo. They changed that from a green circle to a red square.

Another strange assumption Why do you think so?!.. Do you have an idea how LCD display works?

yes, I know how LCD Displays work. The ammount of power it takes more to show a black image i just so tiny, that it doesn't really matter.

I don't understand what you are trying to say but black pixels does not required power at all So, "black-on-black" is a most "energy-saving theme" unless it's just useless

on regular LCD displays they actually do, as pixels are translucent by default. It requires energy to "shut them" in order to display black.

That’s right - the EL light in the back is one sheet and it is always on (when powered up). Think of the pixels as shutters letting the light through-
I cannot imagine that one color scheme vs. another could make a measurable difference.

Guys, LCD uses a few slightly different technologies... Are you talking about old STN (Super Twisted Nematic) implementation? Forget about it! Try to google about TFD/TFT...

HTC HD7 use a twisted nematic display

In Malaysia, maxis gave out wp7 with default green color as its their corporate color. Celcom gave out w default blue theme.. I guess it's d operator thing..

Screen quality???

I just got my Nexus 5 in the mail and have some questions about its screen
First, what's the material used for the screen?
Second, is anyone having some serious yeloow hue going on with their screens????
I own both the Z1 and the N5 now and will decide to sell one off in the near future. The Z1 was notorious for their yellow hue screen and comparing the N5 side to side with the Z1 the N5 is even worse when it comes to the yellow hue. Can anyone else confirm?

Want to post a side by side comparison pic but the only cameras I own are on the phones haha

Do a search on the forum, there are a number of threads about the yellow tint. Some N5s have it, some don't.

Finally got around to taking a photo with my friend's 5S
On the left is the N5 and Z1 on the right.
The yellow hue is definately more noticable when viewing screens with slight hints of blue
The comparison of both white screens came out decent in the photo with slight yellow on the N5 but in person it's much worse. (keep in mind my Z1 already has a yellow hue problem)
Definately feel like my N5 has serious screen issues I will contact Google and see what they have to say

Yes, it's very difficult to photograph the issue because the device used to make the photos has its own impact. I've found that you can take whatever the photo shows and multiply it by a few times to get a real indication of the difference.

Horizontal lines in blue and gray areas

Hi,
Two weeks ago, I bought the Moto G. It is a great device. However I made a strange discovery.
When the brightness is high, there seem to be horizontal lines in blue and gray colors like the
facebook icon. You need to look very close to see them. When I looked at the display with a
magnifieng glass, every second line of pixels where in a lighter colour as the others.
All images are very sharp.but still the pixel-lines can be made out. If this is normal, then I will
live with this.
Thanks for any information

That doesn't sound normal. Could you take a close up picture of the affected area? Anyways I would definitely request a replacement.

I just found a thread including a picture which exactly describes the issue.https://www.google.com/url?q=http:/...ds-cse&usg=AFQjCNGaI4cLfsNaFK0vygdf_32mc49XyA

I tried to reproduce that image for you on my moto g with the Facebook icon and this is what it looks like

As you can see it doesn't very similar to the picture that user you linked posted, so I do think there's a defect in your screen.

Thanks for the fast reply. My picture however is only an example for the effect. When I zoom into your picture, I can also see the horizontal lines in the screen. Especially in the right sie oft the Google search bar and in the battery Symbol. The whole screen is made out of horizontal pixel lines. So I presume that all moto g will be like that. But I am suprised that I can See the lines with my bare eye in a HD screen.

Hi,
today I received my cristal clear screen protector. As soon as it was on the screen, the issue with the horizontal lines nearly vanished.
I don`t know why that happend but a screen protector solved it for me.

I've noticed the exact same issue on my MOTO G.
And i'm very surpised to see horizontal lines on an HD screen. I have also a Sony Xperia Neo V with much lower pixel density (265 i think) and it's very crisp and smooth with no lines at all..
My wife has also the same issue on her MOTO G.
It's present only horizontally and when you look the screen in a slight angle upwards..No downwards. When i change screen orientation to landscape the 'lines' are always there.. but now vertical.
They are present in the 1280 side and not in the 720. i think that every second pixel line is white.. Like i have 640 pixels only. That's happening in solid colors background and especially in grey, blue and green colors (like in the green message icon, or most noticabely in the grey keyboard buttons and in the battery icon on the status bar).
That's very strange and i don't know if i'm going my phone to the service because maybe they think that i'm too weird looking for such small things with a very nice handset by any other means..
Thank you very much and sorry for my bad english

Samsung A7 (2018) Black Crush Screen Issue

I recently bought Samsung A7 phone.My problem is that especially during night time in a dark room when i am watching Trailers or movies in You tube or any other Digital streaming app i found a color banding issue that prevents the screen from accurately displaying different shades of black. As a result, an image or video with colors that fade from black to dark gray might replace some of the grays with black. On top of that, the dark areas of the image may before grainy or pixelated.

During daytime this issue is redundant.
This issue also happened with Galaxy S9 also.But samsung released an update to resolve this issue.Is this issue occurring on only my phone or is this a defect in the phone.Can anyone provide me a solution for this?(Please find attached image for Reference taken in my phone)

In this test http://www.lagom.nl/lcd-test/black.php#blacktest.png I can distinguish the squares from 6 to the last without problems on 50% brightness.
At 100% brightness I can also see square 5, but 1,2,3,4 looks the same as 5.
So does that count as black crush?
Until now I haven`t see any problem when watching videos, everything looks crystal clear for me.
Look at this https://i.imgur.com/Y1snoFf.jpg and tell me how many boxes you can see.
At 50% brightness I can differentiate every step from 3% (1,2 and 3 looks almost the same) to 100%.
I just tested this with minimum brightness in room without light and I still can see every step, actually in that way 1 and 2% are also visible as separate.

Same problem here. Same phone. I tought it will be fixed with february update, but it wasn't. I think it's software related. I also have the uneven display problem.

Are you shure this ja the screen problem nad not the compression effect ?

Can't see the picture but I might know what you talking about.
My F2 has also vertical "spots" in low light/dark conditions when there also dark content displayed on the screen.
I think it is normal for OLED Screens, although I must say it is quite visible on the Poco f2.

Yes it appears in dark condition specialy on grey, dark grey color and a lot of apps using it in dark mode so it's normal no need to change the phone

Yes exactly. I must admit it is quite irritating seeing those at first; these "shadow lines" are especially more prominent when the DC dimming feature is activated.
I had those on every phone with OLED Screens (Galaxy S, S2, S3 etc. you name it) and also on the OnePlus 6.
I assume OLED Screens are not perfectly balanced out regarding their illumination strength or there are slight impurities/imperfections in the panel, since these are organic light emitting diodes. But I don't really know why these lines appear especially in low light conditions.
Other than that it does not bug me much (anymore) since in most use cases the lines/shadows are not visible.
