Apple might now go the Samsung way and may reportedly manufacture a 5.8-inch iPhone featuring rigid AMOLED display panels in 2018 or even earlier in 2017.
Samsung Display has been picked as Apple’s first candidate to supply AMOLED (Active-Matrix Organic Light-Emitting Diode) panels while LG Display and Japan Display will be added later as AMOLED suppliers. All three companies already supply Apple with mobile screens.
It is believed that Apple might be prepping a major switch to OLED screen technology for iPhones by 2018, which indicates that one should not expect an (AM)OLED iPhone before an ‘iPhone 8’ refresh in 2018. The report states that Apple is estimated to ship about 50 million AMOLED iPhones in the first year of availability.
Apple is reportedly planning to release two variants of its large-screen iPhone 7 Plus this year out of which, one will be with a single-lens camera and one with a dual-lens camera. The dual-lens variant has been rumoured to be marketed as the iPhone Pro respectively.
In addition, we’ve so far known that Apple is working on a new 4-inch iPhone called 5se, as it toted to be an upgraded 2013 5s model. According to a report by 9To5Mac, the upcoming 4-inch iPhone will be called SE and not iPhone 5se. The company has decided to drop ‘5’ from the name. This means, the iPhone SE will be the first ever upgraded model without a number in its name
The unique way in which our fingertips can detect changes in both temperature and pressure have been reproduced in an electronic 'skin'.
In tests, the grooves in the e-skin were able to respond to water droplets running across them and could detect when a human hair was placed on their surface.
The breakthrough could be used to make more life-like prostheses or improve the accuracy of wearable sensors and medical diagnostic devices.
The electronic skin was developed by researchers at the Ulsan National Institute of Science and Technology, led by Professor Jonghwa Park.
Human skin contains unique epidermal and dermal microstructures and sensory receptors.
The microridges on the fingertip are especially designed to fine-tune perception of surface texture and transfer sensory information to the brain.
Existing electronic skin technology lets robots and robotic prostheses grasp and manipulate objects, discern the surface texture and hardness, and feel the warmth of objects.
However, electronic skins that can simultaneously detect both heat and different types of pressure with a level of high sensitivity have been a difficult to develop, until now.
Professor Park and his colleagues have designed ferroelectric films that mimic the grooved, microscopically 'mountainous' structure of human fingertip skin.
By adding composites made of a polymer and reduced graphene oxide, the films are able to detect touch and temperature using sensing electric charges.
The authors tested the e-skin's response to sensory changes created by water droplets and found that the skins can detect water falling at different pressures and temperatures.
They also found that the artificial fingertip skin could detect a tiny amount of pressure created by a human hair.
And when attached to a human wrist, Professor Park and colleagues said their e-skin can be used to monitor pulse pressure by detecting the changes in skin temperature that occur when blood vessels dilate or constrict.
Last month, researchers from Stanford University developed touch-sensitive artificial skin that not only detects pressure, but can transmit signals to nerve cells.
They hope the proof-of-concept experiment will lead to artificial hands that allow the wearer to feel different textures and distinguish between hot and cold.
Electronic SKIN can 'feel' heat and pressure at the same time: Film is so sensitive it can tell when a human hair is placed on it
- Human skin contains unique microstructures and sensory receptors
- Researchers have mimicked these structures in an electronic film
- The grooved surface is made from plastic and graphene oxide and can detect touch and temperature using electric charges
- It is so sensitive it can detect the weight of a human hair being placed on it
