A Novel Touch Panel Design for High Optical Transmittance for
Interactive Displays
Abstract
In this article, we propose a new sensor architecture, in which
electrodes are settled at the edge of the touch panel, ensuring a very
high optical transmittance. The touch event detection relies on
electrical capacitance tomography (ECT) technique. The presented
technique provides a feasible means to boost the optical transmittance
of the touch panel layer while maintaining touch detection accuracy.
