Apple’s New Touch Screen Technology Could Improve iPhone’s Battery Life

Presently, transparent touch sensors are laid over image displaying pixels in order to achieve the touch input functionalities without interfering with the display of images. However, Apple says this has a few potential disadvantages like adding weight and thickness to the display screens. Also thanks to the touch input overlay, the brightness of the images are also reduced.
To tackle this, Apple has developed a dual-function capacitive element that will enable the pixels to not only display images but also make them capable of registering touch input. In their patent, the inventors write:
“[T]hese dual-function capacitive elements form part of the display system that generates an image on the display, and also form part of a touch sensing system that senses touch events on or near the display. The capacitive elements can be, for example, capacitors in pixels of an LCD display that are configured to operate individually, each as a pixel storage capacitor, or electrode, of a pixel in the display system, and are also configured to operate collectively as elements of the touch sensing system. In this way, for example, a display with integrated touch sensing capability may be manufactured using fewer parts and/or processing steps, and the display itself may be thinner and brighter. ”
The patent is of highly technical nature and common iPhone users may not be able to discern the thinning down of display screens or improvement in brightness. However, a great take-away from this recently published patent is that it would mean more optimized battery usage for display purposes. Technology as this as well as deployment of
could come with a much improved battery life.
