Everybody loves rumors. But this new iPhone rumor comes out right at the same time news of first discovered ransom wear on Mac is found. Kinda funny?! BUT, iPhone 7 may have OLED screens and we get nerdy over OLED details.
Apple is likely going to go the way of OLED. Finally. I’m actually surprized that Apple has been able to keep up in the ‘mobile thinnest phone in the world’ title. Samsung has been using OLED for a few generations now and has bennefited from not having to add a backlight; increasing the thickness of the phone.
I like Apple. I’m an osX fan. With that said, I know as well as the next techie that Apple will call the OLED something fancy. They’ll boast about how they worked closely with the OLED manufacturer (bet in LG) in perfecting the color reproduction of it. Tim Cook has stated issues with OLED color reproduction, but this was 3 years ago. Another prediction I have is that Apple will desperately make this iPhone very thin. Afterall, they need to save the big advancement for the 10 year anniversary iPhone.
What if Apple uses bi-directional OLED screens? A company in 2011 had a working prototype. It could mean you could scan things on the screen of your phone, or maybe even have touch ID anywhere on screen.
Probably just an AMOLED screen with a fancy marketing term.
A quick run down on how OLED screens work differently than traditional LCDs.
Each pixle on an OLED screen produces it’s own light. Where an LCD does not. To visibly see an LCD, light must pass through the opaque pixel.
There are a variety of OLED types.
PMOLED -passive-matrix: Meaning only m + n control signals are required to address a m × n display. (Yay Discreet Math! Attached bonus Discrete Matrices PDF)
AMOLED – active-matrix: Requires a TFT backpane to power cycle each pixel. Basicly this method actively maintains the pixels state and handels each pixel with a transistor and capacitor to chnage the state and keep crosstalk issues from happening. (A TFT is also used with LCDs.)
Different types of light emitting LEDs:
OLED use Phosphorescent organic materials to create light emitting pixels.
PLED use Polymer Diodes to create a light emitting pixel.
So, what’s the problems with OLED? Well, they have gotten much better with color reproduction. They also have seemed to get the life span of the LEDs up. However, even my galaxy Note 3 had ‘burn in’ issues. It’s not really burning in the screen like a CRT, it’s usually one the brightness has degraded of one particular color in that area, which makes it look burned in.
BUT! OLEDs can bend. So, all the negatives disappear. Foldable screens!
More Bonus information! The first consumer laptop to use an Active Matrix LCD panel was Apple in 1998!
