Qu’est-il arrivé aux écrans 120Hz ?

What happened to 120Hz screens?

Avant d’acquérir un smartphone pliable, il faut absolument regarder les différents appareils disponibles sur le marché. Lequel, permettra vraiment de lire les jokes tous les jours de manière confortable ?

si vous avez joué avec un iPad écran TrueMotion Pro, vous comprenez une fois que vous jouez avec écran 120Hz. Il est difficile de revenir à une normale 60Hz. L’iPad Pro a été dévoilé quelques années revient avec cette technologie, il rend la navigation de l’appareil tout rapide et sans effort. Avec tout simplement pas bégayer, bonne animations tout au long.

Pourquoi la série Galaxy S10 n’avais 120Hz.

Je comprends qu’un écran OLED est plus difficile à produire un téléphone pour 120 Hz. Razer téléphone 1 et 2 à la fois avoir 120Hz. Et a eu cette fonctionnalité pour plus d’un an.

Téléphones aient des écrans 120Hz ? Quels sont les inconvénients. Il aurait aidé justifier le prix plus.

  1. The Razer phone wasn’t oled, and also atm there aren’t any 1440p AMOLED mobile screens with 120hz. I’d imagine that with the how high end Samsung’s displays are it’s pretty hard to also make them 120hz.

  2. The Razer phones are also LCD panels, but…the ASUS ROG phone is an OLED with 90Hz so it’s possible to go above 60…don’t know why Samsung hasn’t at least made it an option yet.

  3. Are the razer phones not LCD? I have an iPad Pro 10.5 and a Note 9 and if the choice is between 120Hz LCD or 60Hz AMOLED then it’s easily AMOLED for me. I prefeAMOLED that much more than LCD that I think that my next tablet will be a Galaxy Tab.

  4. Like any technology, 120Hz has tradeoffs — a higher refresh rate is very nice to have, but it would increase cost and power usage.

    iPad’s 120Hz display can also be run at 24Hz or 48Hz when appropriate to save energy (there are huge swaths of time in-between scrolling). By being LCD the backlight is able to be run constantly at whatever brightness is needed. “When appropriate” implies some amount of logic in the OS for determining how to run the panel based on usage and displayed content and if Google will eventually do this work it’s probably not attractive for most vendors to get ahead of that.

    With OLED each pixel self-illuminates. Current flagship displays use PWM dimming to achieve low brightness with good accuracy. PWM is run at 240Hz, so it seems like it should be possible to get variable refresh and PWM dimming to work together at frequencies with common multiples, but I imagine it does add complication (cost). On PC VRR displays I believe frame rate can be altered close to continuously within the supported range, which makes mitigating a sub-maximum frame rate simpler.

    I think the major deal-breaker is that people want cheaper phones with better battery life more than 120Hz. Running a 120Hz display at 120Hz does use more energy than running a display at 60Hz.

    As pointed out many times previously, PSVR has a phone-size 120Hz 1080p AMOLED display and it shipped in October 2016, so the raw technical capacity definitely exists for 120Hz OLED, it’s just lower priority than cameras, HDR, battery life, cost, etc.

    Edit: Razer has already shipped variable refresh rate LCD, so at least one vendor didn’t mind doing the work of getting that going. Also, Andreif pointed out that 2560 x 1440 x 2 subpixels x 10 bits (HDR) x 60Hz just squeaks in under the limit for a single D-PHY 2.0 MIPI lane (4500 Mbps), and running a single lane is going to be cheaper and use less energy than two. Again, anyone could run up to four lanes but it has to result in a product that sells better than one using those resources for other features or one that costs less and runs longer.

  5. Got to wait until they put one in an iPhone and then all the Android manufacturers will be scrambling to do it too. Looking forward to it as it’s the only thing I see myself upgrading for any time soon

  6. As you said, OLED and 120hz will not happen anytime soon.
    And most people prefer OLED over LCD 120hz I guess.

    I personally prefer 120hz LCD over OLED blacks, then again I am someone who refuses to use a 60hz monitor on PC as well so 😀

  7. I know there are battery issues with a higher refresh rate, but I’d rather phone companies had thrown their efforts into improving the technology than selling phones with 5 cameras.

  8. I used a Razer Phone for a while and I gotta say, it’s fuckin magical. I honestly think it’s just because the average consumer (until they use it) doesn’t see a huge difference between 60Hz and 120Hz. As long as companies like Apple and Samsung can get away with sticking 60Hz screens in phones that cost more than my first car, I don’t think many smaller companies will take that leap. And as you said, OLED panels aren’t as easy to make 120Hz. Unless Samsung (a major display panel provider) adopts that technology, I’d expect any 120Hz OLED phones to be expensive as shit. LCD panels are the way to go for 120Hz (right now) and many people aren’t willing to use an LCD over an OLED panel even for 120Hz butteriness. But Razer is making really promising products right now. I’m currently using a Pixel, but I’m REALLY tempted to buy a Razer Phone 2 (even tho it’s old now) because I miss that butteriness.

  9. Google will never figure out an algorithm that scales the refresh rate to save battery. They are useless when it comes to these broad device mechanisms. Just wait for *insert no name Chinese OEM* to implement a half baked solution for getting this in phones.

  10. Higher refresh rate displays and digitizers would be the single biggest improvement in phones. But instead they focus on putting 5 (mediocre) cameras in them now.. It’s really a shame.

  11. Oled cant do 120hz this small and still be efficient, Samsung uses LCD for their gaming monitors and tvs for a reason, black smearing. Plus android has much higher touch latency than iOS so it is a waste, you cant benefit from it for anyting other than animations and media. I owned the Razer 1 and it doesn’t actually run in 120hz for pretty much anything, it scales the refresh rate.

  12. The next mainstream phone that has 120 hz display will be mine. I don’t care if it’s Samsung, Huawei, LG or even Apple. I have been using Pixel/Nexus phones since the beginning and there is nothing new on Android that excites me anymore. I just want a really good jump in user experience and I think only a phone with good all around specs and a 120 hz display can do it (for me).

  13. > Why didn’t the Galaxy S10 series have 120Hz.

    because samsung didn’t want it to. they have to make phones for the next 100 years, you think they’re going to give away good new features just like that? they’re holding this shit. the samsung vr displays are high refresh because vr NEEDS it.

  14. I don’t know. I am waiting eagerly for this to become a trend.

    60hz has been the norm for a long time but 120hz is 10 times better. I understand there are people who feel motion-sickness when they look at anything greater than 60hz but that doesn’t mean the rest of the world is also feeling sick.

    I expected the S10 series to land with at least 90Hz displays and well… 60Hz displays for another year. But honestly, I am at this point considering going with the Razer Phone 3 when it will launch strictly because in my country we get Exynos variants for Samsung devices(and I’m done with Exynos, not because it’s shit but because it has close to 0 dev support and only a handful of apps make proper use of it and because every year the exynos variants have a quirk or two that just make it slower than the SD variant).

    I want the power that Snapdragon has (not in benchmarks but in real life scenarios) and I also want 120Hz displays to be in the palm of my hand and Razer Phone 3 will be a fantastic phone for that task.
