Touch screen experts Peratech have created a solution for touch screen applications that allows for a more energy efficient system. Due to the QTC Ultra Sensor being placed behind the screen, there is no loss of light from the display, meaning less battery is used.
This technology has been working best with OLED and e-paper type displays but can also be used on other products. LCD is not advised as they cannot really be pressed. Normally touch screen devices require a layer over the top of the display, which causes slight light loss, so having the technology behind the screen means brightness and quality in the image will not be lost.
QTC, which stands for Quantum Tunnelling Composite material, means the material changes its resistance when pressure is applied and only then. It means power is only used when the screen is touched, unlike previous technologies that need continual power for the active sensing matric. Apparently the QTC will also be a lot cheaper, due to limitless size opportunities regardless of the matrix interference and the company have already made examples that are 2m by 1m.
It will probably be a while until this concept is brought onto the high street, so if you have any queries or requirements involving touch screen now, please feel free to contact us.
