When the new iPhone 7 series got introduced in September, many criticised Apple for lack of improvements in the device's design language as compared to its predecessor, the iPhone 6S series. But not many know that the Cupertino-based company restrained itself from making a major overhaul in the models of 2016, and is planning to make radical changes in the handsets coming in 2017, as the year marks the 10th anniversary of its first iPhone.

So far, Apple is maintaining a stony silence about its plans for the iPhone 8 series, but its supply partner Sharp just couldn't keep mum. It has just revealed a key detail of the upcoming phone.

Tai Jeng-wu, the President of Sharp and also a Foxconn executive, during a talk at the Tatung University, told students that the iPhone 8 will come with Organic Light Emitting Diode (OLED)-based display, a huge improvement over the Liquid Crystal Display (LCD) screen used in the current iPhone 7 series and older devices.

OLED is more power efficient and also known to reproduce more accurate image colours, as each pixel provides its own illumination, while all of the pixels in a LCD screen are illuminated by an LED back-light. Using LED has another benefit too — the brightness of an OLED display can be controlled pixel-by-pixel, wherein it allows the device to have Always On Display (AOD), like we see in the flagship Moto series.

Once the AOD feature is activated, a certain section of the display will always remain active to show live notifications, local weather and time, so that users don't need to press the power button to open the phone to see the time or messages. This will be a really big addition to Apple iPhones.

Apple iPhone 8 series: What we know so far
From what we have gathered so far, Apple iPhone 8 series is expected to come in three screen sizes — 4.7-inch, 5.0-inch and 5.5-inch.

Except the display size, all the models will have the same internal hardware and come with A11 series chipset, which is said be more efficient and powerful as compared to iPhone 7 series.
