A closer look at the LG G5's always on display feature

A closer look at the LG G5's always on display feature

With the hot, new G5, LG introduced a pretty interesting feature for its IPS LCD displays – the always on screen. Much like we've seen on the LG V10's secondary screen, the G5's display can keep a backlight on for about 30% of its normal brightness and have a small area of the screen display a few items, such as time, a personal message, and pending chat notifications.

The always on feature consumes up to 0.8% of battery per hour, according to LG. It is smart enough to adjust its brightness depending on environment luminance, so the number could be lower than that in specific scenarios. Still, this sounds bad to some in theory, as simple maths translate it as an 8% drain just from the display in 10 hour of standby. But the idea is that since users don't need to fully light up their screen to check for the time or notifications, the feature would actually save up on battery in the grand scheme of things. Of course, it remains to be seen how the G5 performs in the battery life department when we get a unit of our own.

Check out the video below to see a close look at the always on screen's options and functionality. Will you be leaving this on, or will you just turn it off and forget about it?

is there a chance that G Flex 2 with POLED display will get this feature?

"LG introduced a feature, which is a first for IPS LCD " Lumia 1520 i'm pretty certain has this feature

the difference here is that the lumia 1520 turned up the whole screen (in black) and showed time, date and notificatios. The G5 i guess figured out a way to turn on only the necessary pixels. my doubt here is how this is getting so much hype when amoled screens have been doing it since symbian era. :/

Nope. Only OLEDs have that Ability

I read a couple times that IPS Quantum displays (the technology LG has been using since the G4) also might have the ability to turn individual pixels on and off. Maybe LG found a way to achieve this.

I know that was nokia that they used display memory with a secondary screen !

No, Quantum LED's will have that, in the process they will kill OLED's :), but no one still use them, we are at least 5 years from commercialization of that technology. Sony [maybe LG too] use Quantum dot's displays. Totally different thing and more a marketing than substance.

LG mentioned only a third of the screen lights up, through separating the backlights perhaps?

exactly what I think.. maybe they use separate power-efficient backlit that only lit that part

No, the display backlight is different in this panel. It is not lighting up the phone screen, which explains why it will only drain 0.8% per hour. If the whole screen lit up it would be higher.

I think it's getting hyped because it's an LCD. AMOLED displays can naturally do it, but LCD's can't really disable the backlight like that

Correct, sir, the "Glance Screen". Perhaps it is arguable that LG's feature is different on hardware level, or for the fact that it's "smart", but that's a moot point until we get the G5 / some more information on the tech behind it.

It uses some kind of local dimming technology(used in high-end TVs). It basically can turn on only a particular area of backlight and turn off the rest. In the case of G5, it lights up only 1/3rd of screen. In case of TVs, it was used to go closer to the contrast and black levels of plasma TVs. With OLED TVs coming, it's a moot point now.

Wait. Lg and Samsung promote it the same with more than 150 times display check in standby mode. Which they say again is 20x more battery efficient than checking it over and over again. Lg uses local dimming technology with the 1nit lowest backlight power possible. Samsung uses the lowest 2nits for the white pixels. Samsung uses 1% over lg 0.6-0.8%power per hour. Lg uses their own dedicated display processor 3a and G ram. While Samsung uses its processor for moving display to prevent burning, image retention, light leaking neighbor, residual color etc. Lg can put images on for long time, not just black and white with little color like Samsung does.

It's basically better on lg is almost every way. Especially if you count how deep black lg's newest IPS quantum when it's in off. Darker than Samsung panel (which always darker in regular than LCD). What I'm afraid is the dead pixel which can leak to the surrounding, getting bigger and more broken with age. When one pixel is dead, no light can go out, it's trapped inside or burning the neighbor pixel, which make them dead too, spread like virus with no option to help. Especially with super small liquid crystal there. Hope you know what I mean.

And BTW lg has it long long long time ago on their java phone, especially the touch screen one.

25. TyrionLannister unregistered

Samsung's is 60 nit for white pixels BTW. Not sure about LG's.

Umm, I have had this feature on my droid turbo for the last year and a half.

23. DFranch

No, the droid turbo isn't always on. It turns on when the proximity sensor detects movement. The G5 screen is always on. Not worth a 20% battery drain in a 24 hour period IMHO.

will the clock move around to prevent burning in?

LCDs don't have burn-in issues

HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA HAHA Woah! That's too much for an old lad, now isn't it??? Too childish, eh? Anyhow, reason I'm grinning like a crazy monkey on steroids (What?) is because my few decades old Nokia 3310 (Hands Down, NOW!) has that very same feature...! Boy, am I proud! Seems like LG is WAY TOO F-ING LATE to the party...! And Nokia, RISE FROM THE ASHES... Like a PHOENIX! And dethrone The Fruity and Sammy... Talk about Day dreaming!

Lmfao death to Samsung. In you're dreams. Maybe to the bad bully iFruit.

3310 is not a smartphone, but a dumbass phone. The Nokia E series and N series yes.

@S.R.K. 3310 a dumbass phone??? What?!! And yet your so claimed "Smart@rse" phone doesn't have the feature of a "Dumb@rse" phone!!! Guess who's laughing now, eh?!! Me and my ol' buddy, The 3310!!!

yeah right, even my rechargeable tamagotchi (that obviously older than your 310) also have always on display -_- but its screen tottaly different with G5's... its more like calculator display, or digital watch screen (without backlit)
