Apple looks to e-ink displays for foldable phones
Apple is testing out e-ink displays for foldable phones according to reports.
“Apple is testing E Ink’s Electronic Paper Display (EPD) for future foldable device’s cover screen & tablet-like applications,” said Ming-Chi Kuo, an analyst at TF International Securities in Taiwan. “The colour EPD has the potential to become a mainstream solution for foldable devices’ must-have cover/second screen thanks to its excellent power-saving.”
The leading technology supplier, E Ink, last month launched its high resolution Gallery 3 colour ePaper for the eReader and eNote markets.
Gallery 3 is based on the E Ink ACeP Advanced Colour ePaper platform. This uses a four particle ink system: cyan, magenta, yellow and white, which allows a full colour gamut at each pixel.
In Gallery 3, the black and white update time has been improved to 350ms, the fast colour mode is 500ms, standard colour mode is 750-1000ms and best colour is achieved at 1500ms. This is a substantial improvement over the first generation of E Ink Gallery, which had a black and white update time of two seconds and colour updates of ten seconds.
The Apple designs are reported to be using e ink displays as the second display that can have a longer update time than the main screen.
Gallery 3 will also have an improved resolution of 300 pixels per inch (ppi) versus the earlier 150ppi and an operating temperature of 0-50 degrees Celsius, on par with black and white eReaders.
E Ink Gallery 3 will also support pen input in black and white, with an addition of several other colours and an update time of 30 ms.
“For the first time, our Gallery full colour ink platform series can be offered for an enhanced reading and shopping experience for eBooks, and for colourful document viewing and editing in eNotes,” said said Johnson Lee, CEO of E Ink. “We have invested over $100 million dollars in R&D resources and budget to improve every aspect of this technology. Our team across the world has worked tirelessly over the past several years, and has made a product we can all be proud of.”
