Abstract
Technologies are described for pressure sensors used in display devices. In one embodiment, a reference ground layer and sensing pad can be positioned between a display substrate and a window substrate. Additionally, a compression region can be positioned between the display substrate and the window substrate. The compression region can be compressed so as to change a distance between the reference ground layer and the sensing pad. By placing the compression region between the window substrate and the display substrate, the air gap below the display substrate can be removed. In still another embodiment, the sensing pad is aligned over a frit layer, but it is divided into spaced-apart sub-regions that are serially coupled together. Gaps between the sub-regions are sized such that the laser can adequately penetrate through the sensor pad to melt the frit.
