A truly flexible display requires a truly flexible touch screen sensor


Most of today’s portable rigid display devices offer capacitive touchscreen functionality. Consumers have come to expect this technology in all smart devices and tablet computers but experience many frustrations including breakage, accidental use and an inability to operate when wearing insulating materials such as gloves.

 

The DRAS® technology overcomes capacitive touch screen limitations revolutionising next-gen portable devices and wearable-tech, providing greater functionality and control. It delivers superior spatial resolution, can sense finger force and requires no re-calibration. It’s not affected by humidity or temperature swings and only picks up intentional contacts.

 

What’s more the sensor can be made as large as the application requires, enabling large scale flexible TV’s and extensive wall size displays to be developed without increasing the complexity of the hardware interface and without compromising the sensor performance.

 

Next generation smart devices can also be customized in terms of shape, size, resolution, accuracy, flexibility and cost without compromising the ease of interface.
