CptPower, 29 Jan 2020Well in theory is a very nice speech and nicely said. Kudos to you for all the work and effort... moreIt does have a difference, it actually make the experience more pleasant, many peoples who tried it gave really positive feedbacks and it is not just placebo.
Explanations : The difference between a 27" monitor running 1440p and 4K isn't big enough to be worth it (same for over 120Hz or perhaps 175Hz for smartphones), some might even say it isn't visible through it would be false, but a jump from 1080p to 1440p is actually quite noticeable because 1080p while nice can be pushed much further.
The same apply for the ~6" smartphone display, which is the sole reason why Apple made the Retina Display, it have a clear advantage, the main image on the Wiki page show it quite well in "action" :
And the same apply to refresh rate, 24Hz is the minimum where, accounting for image persistence, an average person start to have the illusion of a video and not a rapid succession of images, 60 Hz while over twice as fast seem really fast, but 24 to 30Hz would be a 720p display, 60Hz a 1080p display and 120Hz a 1440p display in term of equivalence of perceived quality, 60Hz became the norm for computer as it is fine for the most common use case of computer : Reading and writing while more than good enough for still allowing a wide range of other applications, but as gaming industry rized, they made monitors specially for gaming, and they quickly understood that higher refresh rate along with low reaction time and low input lag is what is required more than just higher resolution.
Even on a smartwatch a low framerate is easily perceivable, granted a higher resolution can help give an illusion of fluidity because of the image sharpness, but the effect is really little and is more of an illusion, practically, any display size can give a real perceivable improvement in fluidity when the framerate is increased.
Now if manufacturers are smart, they would otp like Oppo for a coprocessor to actually help manage the image and reduce the power consumption, a step further would be to simply have a variable frame rate technology, if there is only a static image, the phone would simply lower the refresh rate at its lowest, but when a fast enough thing is on the screen, the frame rate would simply increase to match it.
But, actually the increase of power drain is way lower than you apparently think, what drain the battery is the backlight who won't change with higher frame rate displays, increasing the framerate would mostly consume more, because it require more computing power to handle it, but the display itself would only have a really minor power increase.
The fact that the Oppo Find X2 will use its own coprocessor to handle the display mean that even at 120Hz the whole display + processing that goes with it might consome actually significantly less than a regular 60Hz display which use the main SoC to compute it.
AnonD-909757, 25 Jan 2020For a while we pushed resolution up, Apple was known for the Retina Display which, as all high... moreWell in theory is a very nice speech and nicely said. Kudos to you for all the work and effort but in practice everything shoved that on a just 6 inch screen the difference between 60Hz and anything bigger like 90 or 120 or even more have no visual difference.
The only difference will be faster battery drain.
Like for example Sony Z5 premium first cellphone capable of 4K resolution had a endurance of 43 minutes set on 4K screen. It took exactly 43 minutes to deplete 100% charged battery to zero.
thada2607, 25 Jan 2020What is an ultra clear screen?For a while we pushed resolution up, Apple was known for the Retina Display which, as all high resolution display on "small" phone have for goal to basically make the image appear clearly without any visible pixels, as the distance we usually are from the phone for its size, such pixel density mean that it appear as we are looking at a real image rather than through a screen, because even if from my ~75cm away from my 1080p 27" display I can't see individual pixels, the image would look more clear on a 4K monitor (though I don't want 4K, 1440 is where it is at, but this is for the example), the more resolution for the size, the more finer the details would look.
But recently we got a new trend on smartphone which is high refresh rate, the idea and goal is that moving things look way better and more fluid through higher refresh rate than lower one, for any display size actually, so the same way that a higher resolution for the same size display will look sharper and give more details on images, a high refresh rate mean that motions (animations, page scrolling, video, video game and other) look more fluid.
I guess "Ultra Clear" mean that thanks to its really high resolution giving a great visual details and its high refresh rate giving a cleaner motion, it will look better and the combinaison of the two can be called "Ultra Clear", but it's more a commercial made up term than a real technical terminology.
On top of that, a high tactile refresh rate mean movement will be more fluidly registered and it will reduce the time lag (a 240Hz will have double touch registration speed of a 120Hz in theory, meaning the lag is smaller) mean that the tactile touch response will also give a more fluid experience, so it simply add to the display perceived quality without changing the display itself.
Of course to properly work the display will require a low response time to reduce the motion blur effect, a faster pixel reaction time (lesser pixels persistence) is required and a low input lag is also required for avoiding a perceivable time of reaction which would ruin the experience and make the higher touch rate useless.
But with a dedicated coprocessor it might be faisable without draining too much battery.
I know GSMArena kind of ripped the OnePlus specs (other than display) and stuck it to the specs sheet for this phone but I'm REALLY hoping it has a headphone jack and hybrid dual SIM at least. The fact that the Find series has US bands makes me really want this device.
Anonymous, 25 Jan 2020Pixel already had a co processor for the camera , and you're not really predicting when it's a... moreYeah it's almost like making a forecast/prediction is based on getting current data and then using it for the future
I think you need to talk to folks like canalyst etc seeing that they predicted an increase in 5g smartphone sales
This might be hard to believe but there is a possibility that co processors won't be trending whatsoever 2 years from now
What is an ultra clear screen?
It's is going to be one the best flagship phone of 2020:)
So 80° mean almost no curve, it just gently add a visual touch without making it easy to hit per accident, don't expose the display too much on the side and while screen protectors will be more expensive than flat ones, they will keep a reasonable price, all that with the ability for cases to easily cover the sides.
I would prefer a flat display, but this is by FAR the best curved display choice, I just hope it will have a great motorised pop up system like its predecessor and will still host advanced and secured facial recognition sensors rather than going for stupid notch or holes !
I hope the hybrid zoom will be optical zoom first (lets say 3 time) then past that a digital one, because optical zoom are by far so much better than digital, mixing them together will just make useless quality loss a low zoom, but my only experience with an hybrid zoom is with my good old PANASONIC HDC-SD80 with his mighty 42x optical zoom and up to 2000x hybrid zoom, the 42x optical zoom as impressively clear and clean, but then, even up to 50x hybrid, we could already saw the quality loss, even in its small display.
I know technology have evolved since, mostly on smartphone with all the post processing, but I still hope it have a two sequence where the optical zoom first and the numerical zoom get on top and not both at the same time.
The fact they use a coprocessor is a great news, a lot of things should actually use coprocessor, they are small, low consumption, and actually get a better job done as they are specialised on their task.
I can't wait to see more about that phone, I just really hope there is proximity sensor, ambiant light sensor (and not using a camera for doing both, same as coprocessor, they are better at their job, consume less power and take little to no space) and real full display with an hidden front camera #privacy and other face related sensors or at least a small bezel like the Meizu 16S which have as close to full screen without using stupid notch or holes, and the result is beautiful, not as beautiful as true fullscreen and the advantage of privacy is loss, but that's the second best solution after pop up camera !
Please Oppo, don't screw this up, it might influence a lot of other devices !
JerryRig will be like: awaiting...
IpsDisplay, 25 Jan 2020Imma make a prediction
We have triple cameras these days so maybe in 2022 well have a trend... morePixel already had a co processor for the camera , and you're not really predicting when it's already happening, you're just reading it online and then repeating it like you thought of it first.
Ohhh I know, I predict phone batteries will increase in capacity size , I predict phones costs will rise
Imma make a prediction
We have triple cameras these days so maybe in 2022 well have a trend for co processors?
Oppo you've done your home work at least they foresaw battery drain issues with 2k displays and 120hz and made counter measures
The Asus Rog 2 feels like a 4000mah battery because of the resolution
The S20 ultral will too on 120hz
