IPhone 6 touch screen will be on-cell, not in-cell [Report]

When the iPhone 5 was introduced, one of the invisible technological innovations was the use of the In-Cell touch system. The touch layer or digitizer is the part that detects the touch of a screen with a fingertip and then converts it into coordinates recognizable to the operating system.

With in-cell technology, Apple integrated this touch layer with the display itself. But now it seems to have taken the opposite path. In the on-cell technology for the iPhone 6, an interactive touch layer will be embedded in the outer protective glass on the screen. In this way, the speed of touch feedback is improved, and as the digitizer is detached from the display, the output image is also improved.

Apple has reportedly signed three companies, LG, Japan Display and Innolux, to produce the iPhone 6 display, leaving out Samsung and Sharp. According to reports, Samsung’s departure was due to Apple’s complicated relationship with the company in recent years, and Sharp has not been able to meet the quality desired by Apple.

The screen resolution of the iPhone 6 is one of the riddles of this phone. Some sources say that 1136 x 640 pixels was chosen for the 4.7-inch model and 1704 by 960 pixels for the 5.5-inch model, but Mark Gorman of 9to5mac  believes that both models will have the same resolution of 1704 x 960 pixels, respectively. It has a pixel density of 416 and 356 pixels per inch and is considered a retina.

The 4.7-inch iPhone is expected to be introduced in the middle of this year (2014) and the 5.5-inch iPhone later in the year.
