Is the LED screen used in iPhones different from AMOLED?

Hi I'm responding to your message written last March, I too have difficulty w the phone due to what is known as the iPhones having motion on their screens. Try going to Settings•General•Assesibility•Reduce motion (to "on")

Have you looked up Irlen Syndrome or Scoptic Sensitivity Syndrome. All of these things have been very helpful to me. For me it's not an opthamolic issue but how my brain processes light.

Hopefully this is helpful!

As I say, there is a lot of confusion and miss-speak about display technology. They ALL use LEDs for the backlight, whether it is one or multiple. The actual display, the thing that renders colors and images, is an LCD. There is no such thing as an LED display except on very large formats like Sports arena boards and such where there is room for thousands of separate LEDs to make up the image. Even the smallest LEDs are too large and would use far too much power collectively to work in any hand held device not to mention that in a small screen they would make for a horrible coarse, low-res display as each pixel would be a physical LED.

OLED is a very different technology than LCD, and as yet, Apple is not using OLED on its devices. OLED's using light emissive organic compounds (i.e. organic compounds that inherently emit light when a current is passed through them). An LCD does not emit any light at all, thus needs a backlight to display the image formed by the LCD.

So the iPhone SE may indeed have more LED backlights than previous iPhone models, but every iPhone model ever made has used LEDs for the backlight function.

No, Apple has not used any AMOLED displays on any of their devices yet. Samsung's Galaxy line may be the best know series with AMOLED displays, but Motorola and Nokia have used them on some of their devices too.

Any LCD display needs a backlight behind it to display anything, and on small hand held devices that has meant LEDs for the white backlight (older computer LED displays and TVs actually used cold cathode ray tubes - fluorescent bulbs). Apple's retina displays are still fairly traditional IPSLCD displays with LEDs for the backlighting. "Retina" is just Apple's trademark name for their higher than standard resolution LCDs.

The terms LED display and LCD display have unfortunately become almost synonymous in market speech. But the actual display is an LCD and the light source that shines through it to display the image are LEDs. An LCD on a iphone without a backlight would appear simply black.

It would be hard to get even lighting with a single LED, so I can see that. There is usually a row along one side, or two, but I do not know how many actually. The one thing I do know is LED technology is not static. CREE LEDs is just down the road from where I work, and they have increased the light output of there's several times in just the last couple of years. So actually manufacturer and type of LED makes a huge difference in light output, power consumption and so on. It could be that the SE is simply using newer, higher output LEDs than the 5 or 5s, which were designed a couple of years ago now.

For example, I have had two Lenovo laptops in the past year - a cheap consumer grade IdeaPad and a newer Yoga (which replaced the IdeaPad). The QED screen on the Yoga is MUCH brighter than the display on the IdeaPad, and in part I've read that is due to higher quality LEDs used on the more expensive Yoga line than Lenovo uses on the IdeaPads. Not all LEDs are equal, so it's not merely how many are packed behind a display, but what type, and quality.

I know CREE LEDs are typically much more expensive than other brands, but CREE's technology also has some of the highest light output of any LED available.

That's alright, you've been more than generous already, and like most of us here, I honestly don't post here for the points. They are just a nice way for all of us here to acknowledge eachother.

I'm eligible for an upgrade myself, from my iPhone 6. I want to wait awhile, until I can see an SE in hand though. I complained about the size of the 6 when it came out, but I've kind of gotten used to it now, so I need to have the 6s and SE in hand at the same time to see decide between them.

Don't forget in the settings about night shift in iOS 9.3 which need not be used merely at night. It doesn't merely dim the backlight but adjusts the light hue as well.
