Always on notification screen (like N9/nokia glance)
« on: November 16, 2013, 09:24:56 AM »
Hey.. Does anyone know if jolla is planning to have this feature?

I know n9 had amoled, and jolla is ips lcd, but if nokia has managed glance screen on lumia 920 but turning the backlit brightness to 1%, then it is still technically possible with the lcd screen?

Any thoughts?

Just that i stare at my nexus5's black screen and really miss my old and very informative n9..,

Even i miss the same... But so far nothing heard from Jolla about this... I think u shld better read the latest post about the interview on Jollausers.

I read it, and while it was very detailed, it didnt really confirm nor deny the always on notification.

The only part that *may* have been relevant was the question about music control on lockscreen, to which the reply was new features will be added/improved upon after initial launch. Not sure if you can extend this answer to all features that are technically possible with the hardware... So still back to square one i suppose

IIRC, they said something along the lines of "it's totally possible to have an always on screen with sailfish os given the right hardware" a few months ago.

maaaaybe they got a higher quality screen with a lower resolution to enable this?!?! the blacks looked very good on the phones  (marcs video where he walks through some UI features, for example). That would indicate a high quality panel being used.

I love this feature on my N9 - and if the slightly lower resolution is the trade off, it's worth it.

But tbh i dont really accept the arguments for a lower res screen... They should have put more in. The only logical reason would be cost cutting.. Theres no reason why a low res lcd would do something a high res one cant, right?

Has anyone noticed they have dropped the term 'estrade' screen lately?  Its no longer used in specs, but originally they explained it as a experience rather than just a screen. Either they have since then retracted this (unlikely) or there is still a surprise with it?

Im hoping anyway..

It hasn't been confirmed by Jolla at any point whether or not they'll feature LPM screen on their phone, but as I recall, in one of their tweets, it has been mentioned that LPM *is* possible on IPS/LCD (like some Lumias) so *maybe* even ifJolla did not include the LPM on their final release on November 27th, there are SW update possibilities (Just like Nokia on their Amber update) and also developers on this fantastic community whom always did their best to bring awesomeness along.
Jolla, Unlike.

Yes, this is correct. At least in some levels...

Some people say it is not possible on any IPS or LCD screens. But it is. Then why these people say it is not? Because there are no actual use for it.

The whole idea for LPM is that it can display a clock, for example. AMOLED is (among the other options) the best solution, because you're able to activate only those specific pixels you use. So e.g. in N9 when you have LPM option on and you see the clock, the whole screen isn't actually activated. It's only those specific pixels. That's the reason why you see the clock a bit 'pixelated'.

LCD and IPC screens do not allow the phone to use only specific pixels. The screen is either on or not. So you could use LPM on any screens, but that would mean you have to force the screen to stay on all the time.

Try it sometimes that you select completely black wallpaper and disable the automatic screen lock. Test how many hours it lasts until it runs all the way down. Not much.

But as seen on one of the Dillon's presentation videos when the screen is waked by double click it's much darker at first. And when Dillon touches it again it gets the whole brightness. So I think it's their way (or at least was around when that video was made) that if you want to see the time in the middle of the night you won't be blinded.  8)

Hope this helps. :)

Less pixels means its easier for the soc to drive it. just like in PC games you get more frames with less resolution. And it should also lover the power drain from battery. ppi of Jolla is enough, no need to go over 300. HTC one is just overkill with around 600 ppi.

Also 4.5" is pretty excellent choice for screen size, it's not too big.

True that the less pixels the less SoC needed to drive it.  But personally im not sure i believe there is much difference between battery life in high/low res screen (purely from the screen power consumption perspective). Since pixels are bigger in low res they would use more or less the same amount of energy to power? Maybe im wrong...i am not an engineer...

I agree a lot of modern phones have far too high ppi for the human eye to notice. But with jolla's at 245ppi, it would be quite noticeable for sure... I mean i notice it on my n9 and that is more pixel dense! Above 300ppi is definitely acceptable. Right now i can only say its usable..

Well i ques it could be more related to screen size. Then again SoC draws less power while running that lower resolution screen.

I'm not an engineer either, but I do believe the amount of pixels has quite a lot to do with battery power. Firstly, that more powerful SoC needed to run those pixels will require more power than the one needed to run a lesser amount of pixels. Secondly, the more there are pixels, the more there are these "individual lights" to turn on and off (simplified), hence more power is needed again.

I'm not saying the qHD resolution on Jolla is the ultimate resolution for a 4,5 inch screen, but I do believe in making the battery last longer rather than going with FullHD...
Jolly and I know it.

Would something like a simplified screen on an Other Half work for something like this?

Have a small, or large, low power screen, maybe even something like e-ink that could show time and notifications for a quick glance.

iv read that there already is a phone with e-ink display on the back side. Would be way cooler tough to have them layered on the same side, should be possible, don't you think.

I really hope there will be a notification screen, which will be always on. I have used to N9 now, and couldn't imagine living without that feature.

Will there be a notification led on the front, somewhere next to that speaker grill. would lave that. In Desire Z it's hidden under the speaker grill: http://i1.ytimg.com/vi/7wAvLaGNxLs/maxresdefault.jpg

blinking green for received messages/unanswered calls. Red for low battery. And when charging, green when the battery gets full. Great little led.
