iPhone 13/13 Pro has been announced.This year, a new high -performance SoC has been adopted as planned, and the camera seems to be evolving with the powerful operational ability of the SoC.Is there any sense of sight?You may think that the announcement event also strongly appealed that the battery duration was increasing.
Regarding the reason why the battery has improved, Apple states that Apple increases the volume assigned to the battery, increases the battery capacity in the first place, and that the A15 Bionic power saving performance is high.
However, although it is difficult to evaluate how far it is contributed to the conditions, the OLED substrate produced in the new process of LTPO should have contributed considerably.
This technology is also related to the PRO Motion that realizes a high refresh rate of 120Hz, and the maximum brightness of the display that can increase the brightness of the entire screen, which is not a peak value, to 1000nits.The degree of contribution to the battery duration depends on the operating conditions, but there is no doubt that it has raised the experience level of the entire terminal, iPhone 13 Pro.
The technology introduced in the Apple Watch is the iPhone 13 Pro
LTPO is a production technology for forming a thin film transistor on a substrate for driving OLED and liquid crystal, which can reduce power consumption compared to conventional production technology.LTPO is an abbreviation for low -temperature and high crystalline oxides, but it is not very important.
LTPO has improved the conventional LTPS production technology, and has the characteristic that the leak current flows to a thin film transistor when driving a pixel is reduced.
In fact, they do not have Apple or production factories, but they invest in OLED -related technological development, and have been interested in LTPO early and have a number of patents.
In the Apple Watch Series 5, the board was displayed when the board was displayed even when sleeping, but at this time the key was OLED using LTPO.The previous model, Series 4, LTPO was adopted, but it could not be dropped to the target electricity, and the frequency of the screen update (refresh rate) is always different (minimum 1Hz).It was lighted.
......, do you feel like you've heard it somewhere?
Yes, it's not a big LTPO, but you'll notice that it looks exactly like the explanation of the iPhone 13 Pro Pro Motion.Apple has worked on using LTPO in another cut in iPhone 13 Pro to improve product power.
Improve the quality of user experience without increasing power consumption
It is said that the power -saving effect by LTPO decreases by about 5 to 15 %, depending on the technical maturity of production manufacturers.However, the cost is 15 to 20 % higher than the conventional production method.
The reason why the iPhone 13 is not adopted and is used in the iPhone 13 Pro/Pro Max is that Samsung Display can only mass -produce large LTPO OLEDs.
At present, Apple's LTPO OLED is also a monopoly supply of Samsung display (iPhone 13/13 mini OLED also supplies LG displays and BoE).LTPO OLED's smartphone panels are also investing in production other than Samsung, so they may be adopted on iPhone other than the Pro line next year.
By the way, LTPO has a lower leak current and the refresh rate can be lowered, but the leak current is a power that is thrown away even when it is not glowing, so there was no significant difference in the "power -saving effect in dark mode."You may be able to expect it.
Interestingly, Apple is reflected in product development as a quality of user experiences, not just reducing the power saving technology.
In the iPhone 13 Pro, the peak brightness of the display has not changed since the previous generation.However, the brightness of the entire screen, which is not a peak value, is up to 1000 NITS, up to 25%from the conventional 800 nits.It seems that the light emission efficiency is equivalent because the peak value has not changed, and the power -saving power -saving amount of power is assigned to the ease of viewing of the screen under fine weather and improving the image quality of HDR content.about it.
In other words, if the brightness is lowered as before, the battery life will be even better.Another thing that could be realized by adopting LTPO OLED is the Pro Motion technology.
LTPO that can hold the display even if refreshing is slow
In the conventional OLED, the display contents could not be retained without continuing to rewrite about 60 times per second.Therefore, even if the screen was not updated, the pixel was rewritten so much.
However, LTPO OLED can hold up to about 1 second (for Apple Watch), and the iPhone 13 Pro can delay rewriting up to 10 times per second.In addition, the driving circuit and iOS are linked to change the number of rewriters adaptively according to the operation of the iPhone and the rewriting of the graphics screen.
The screen of the smartphone is hardly rewritten unless you watch videos.This saves the power to rewrite the OLED panel, but being able to change the refreshing in conjunction with the graphics drawing by iOS means that this time it can be faster than normal (60Hz).is.
The OLED 120Hz drive technology that Apple calls PRO Motion is also a set of 120Hz driving of the touch panel, so it is expected that a comfortable operation feeling that responds as if it were sucked on the finger. can make it, right.
In addition, not only LTPO OLED itself but also Samsung has been adopted since last year.In addition to the latest OPPO models, the new Terminal of Google is LTPO OLED.
Both are driven at 120Hz or 144Hz, but in combination with apps, including experiences such as display quality such as videos and photos, etc., a rival terminal is made from such a maniac perspective.It may be good to compare.
