Apple considering change to its display technology to extend battery life?
by Alan Friedman / Aug 24, 2018, 8:09 PM
Analysis from research firm IHS Markit suggests that Apple might consider a change to a low-temperature polycrystalline oxide (LTPO) backplane, from the current low-temperature polysilicon thin-film transistor (LTPS TFT) currently used on its OLED displays. The backplane is the part of the display used to turn the pixels on and off, and is therefore responsible for the display's power consumption, resolution and refresh rates.
According to the report, Apple has filed three patents related to LTPO in 2014, 2015 and 2018. The analyst behind the report, David Hsieh, does ask an interesting question. If Apple is sourcing its OLED panels from other companies, why is it so interested in creating its own backplane system without working with its OLED suppliers? Hsieh has a few reasons for this:
- To be more closely involved in flexible OLED component cost and technology.
- To reduce power consumption of Apple products.
- To achieve high electron mobility for higher resolution of its displays.
- To better manage its display supply chain and that of its partner-display manufacturers.
Battery life could be extended anywhere from 5% to 15% using LTPO (view the image at the top of the display). But not everything about LTPO is positive at the moment. Right now, LTPO requires larger thin-film transistors, which means fewer transistors in the display substrate. That would mean lower resolution screens. And the larger photomask needed for this technology (20% larger than LTPS) requires more expensive equipment; additionally, the process of producing the components for LTPO is more complex.
According to Hsieh, Apple might audition the LTPO backplane on the smaller Apple Watch display before using the technology on the iPhone.

Great innovations are coming to my apple products.

Imagine how good it will be if apple actually incorporates a new radical battery tech that we all know is currently available!! Yeah they have contract agreements in place that force them to keep using lithium (dangerous) based battery tech...but when those contracts are up - well it's highly likely that apple will be one of the first to implement safe battery tech for their users.

Don't be delusional, Apple will use the same lithium tech as everyone else because it's cheap. If they actually cared about quality they wouldn't have used low grade aluminium on the iPhone 6, would have used actual sapphire glass on their watches, tested the MacBook pro keyboards better, etc. Etc.

For one a contract don’t mean crapp. If there actually is such a thing for battery manufactures. That’s a conspiracy theory at best. If they put every technology into a phone that they possibility could you would be talking about a $2000 to $3000 phone that would not sell that well. The batteries that they have are about as safe as can be. Otherwise they would have made the charging for wired and wireless a lot faster.

You should get a job with Apple and make sure they are among the first to implement safe battery tech for their users. I'm sure Apple can't afford to pay you what you currently earn, but you'd be doing us Apple users a favor, so consider it a public service.

Samsung's OLED displays aren't the biggest culprit of heavy power consumption on The iPhone X; it's the SoC. Apple A Series might blow Snapdragon 8xx out of the water in terms of performance; but its no where near efficient. An iPhone 8 Plus draws a whooping 9w from its minuscule 2,600mAh battery at full load; 2.52w on idle with display turned on. While The S8 Plus draws just a tad over 5.2w from its 3,500mAh battery; 1.16w on idle and 0.13w while on stand-by with 'always on display' enabled. So like I said; its not OLED Displays to blame; it's the Apple A11 SoC. Seems like someone can learn a lesson or two from Samsung and Qualcomm! Oh well, G'Day! [Source: Notebookcheck.com]

Mostly on paper though (Geekbench benchmarks), real world usage these phones one up each other in performance. Most system apps open faster on the Note 9, most games on the iPhone X. RAM management is where the Note 9 stands tall though, all that RAM really shows. Overalll, two great phones, and I’m glad I own both. iOS for iPhone sorely needs true split screen multitasking though, too much power, and too big a screen not to have it.

Or they could just put a bigger battery in the damn phone...

Year into my iPhone and it last a whole day easy with heavy use. Every android phone I’ve ever owned starts to poop out after about six months where I have to charge at least one time throughout the day

It is easier if they add 500mAh to each new model from now. I doubt the 6.5" will have more than 2900

The fact they put 2600mAh in the 5.8" iPhone which is approximately the same size as the 1800mAh iPhones, they seem to be adding ~800mAh to the models, that's put the 6.5" iPhone at 3300-3500mAh. Those capacities sound possible.

5-15% saving on the screen, overall 2-5% assuming a very generous one third of all power consumed is used by the screen. They're are far better off putting a bigger battery of 500mah. Another brilliant innovation by Apple. LOL

Just because Apple holds a patent does not mean they intend to use it. Apple actually uses less than 0.005% of the patents it applies for yearly. Tech companys try to patent every single idea they can possibly think of, the vast majority are never used.

Isn't the LTPS TFT a LCD technology? We're talking about the LCD panels, not OLEDs.

Apple OLEDs must be china fakes??
