Display type is one of the many other factors people use, to decide on which phone they want to purchase. Many users look at the size of the display, but with recent advancements and increase in the number of display types entering the market, users are confused which display type is actually better and which might eat up more battery of the smartphone.
So let us compare between the AMOLED display, which is used in several Android devices (especially the ones from Samsung) and the Retina display which is used by Apple in the iPhone. Let us put it in one sentence, AMOLED display uses LED technology as given in the name and the Retina display relies on LCD technology.
The term “AMOLED” stands for Active-Matrix Organic Light Emitting Diode, which takes help from three discrete LEDs present in each pixel. These LEDs produce their own light and do not need any backlight or external light. On the other hand, Retina Display relies on LCD technology, where a backlight is needed and the pixels do not produce their own light.
This feature helps the AMOLED display to conserve more power as the individual LEDs will turn off when black is needed on the display and this will conserve more energy in comparison to Retina display, where even if it is a black background, the backlight will be ON always, and this also gives a greyish color to the black. Retina display has its own advantages, as it has higher resolution in comparison to AMOLED displays, which Apple claims to have a resolution so high, which human eye cannot discriminate.
In retina displays, you can achieve more pixels per inch in comparison to AMOLED displays, which results in better resolution in retina display producing a very fine image on the display.
With the LEDs turning off to display black, the power consumption is decreased as well as improving the contrast to infinity. In case of sunlight the Retina display wins it here, as the AMOLED display produces its own light which can be overpowered by the sun which makes it look dull.
If you look at some of the important aspects in which both the display types are compared, the Retina Display has higher resolution in comparison to AMOLED display. The AMOLED display produces higher contrast in comparison to Retina display because of the individual LEDs producing their own light. The Retina Displays are better under direct sunlight than AMOLED displays, and lastly, AMOLED display conserves more power compared to Retina display because of the individual LED producing its own light turning off when needed to display black.
If you see both the displays in person there is not much of a difference in the resolution and the viewing angles etc. It eventually comes down to the number of pixels compared to the display size at offer. And another important factor is your lifestyle and requirement, if you are more of an outdoor person spending more time in the sunlight then Retina display is the one for you compared to the AMOLED display. We do not make a decision only depending on the display type, this is just another factor in many other factors which we look at to choose our next phone or tablet.
