Abstract
A touch-sensitive panel is provided for a display assembly and computing device. Individual cells of the panel are structured to include electrically inactive interior portions or centers to enhance the sensitivity and performance of the panel.
Claims20
A display assembly for a computing device, the display assembly comprising:
- a touch-sensitive panel comprising an array of sensor cells, the array of sensor cells including a first portion of sensor cells that are designated as driver cells, and a second portion of sensor cells that are designated as receiver cells;
- display hardware that is connected to the panel, the display hardware being structured to (i) actively drive a signal on each driver cell;
- and (ii) detect, on each receiver cell, a parasitic signal that is generated from the signal driven one or more driver cells that are adjacent to that receiver cell;
- wherein at least some of the sensor cells are constructed to include a conductive perimeter thickness that surrounds a non-electrically active interior portion.

A touch-sensitive panel comprising:
- an array of sensor cells, the array of sensor cells including a first portion of sensor cells that are designated as driver cells, and a second portion of sensor cells that are designated as receiver cells;
- wherein the array of sensor cells are arranged to (i) actively drive a signal on each driver cell;
- and (ii) detect, on each receiver cell, a parasitic signal that is generated from the signal driven one or more driver cells that are adjacent to that receiver cell;
- wherein at least some of the driver cells and/or the receiver cells are constructed to include a conductive perimeter thickness that surrounds a non-electrically active interior portion.
