Touch-screen panel comprising cells that have holed or dummied interior portions
View Patent ↗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.
1. 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 by 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.
2. The display assembly of claim 1 , wherein individual sensor cells in the array of sensor cells are diamond shaped.
3. The display assembly of claim 1 , wherein individual sensor cells in the array of sensor cells are polygonal in shape.
4. The display assembly of claim 1 , wherein the non-electrically active interior portion of the at least some of the sensor cells is a void.
5. The display assembly of claim 1 , wherein the non-electrically active interior portion of the at least some of the sensor cells is formed from non-conductive material.
6. The display assembly of claim 1 , wherein the non-electrically active interior portion of the at least some of the sensor cells is comprised of a break that separates the conductive perimeter thickness from the interior portion of that sensor cell.
7. The display assembly of claim 6 , wherein the non-electrically active interior portion of individual sensor cells that include the break is grounded.
8. The display assembly of claim 1 , wherein the array of sensor cells is structured to provide the driver cells on one of a row or a column of the array, and the receiver cells on the other of the row or the column of the array.
9. A computing device comprising:
a housing;
a 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 by 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.
10. The computing device of claim 9 , wherein individual sensor cells in the array of sensor cells are diamond shaped.
11. The computing device of claim 9 , wherein individual sensor cells in the array of sensor cells are polygonal in shape.
12. The computing device of claim 9 , wherein the non-electrically active interior portion of the at least some of the sensor cells is a void.
13. The computing device of claim 9 , wherein the non-electrically active interior portion of the at least some of the sensor cells is formed from non-conductive material.
14. The computing device of claim 9 , wherein the non-electrically active interior portion of the at least some of the sensor cells is comprised of a break that separates the conductive perimeter thickness from the interior portion of that sensor cell.
15. The computing device of claim 14 , wherein the non-electrically active interior portion of individual sensor cells that include the break is grounded.
16. The computing device of claim 9 , wherein the array of sensor cells is structured to provide the driver cells on one of a row or a column of the array, and the receiver cells on the other of the row or the column of the array.
17. The computing device of claim 9 , wherein the display assembly further comprises a display element that emits computer-generated content.
18. The computing device of claim 9 , wherein the computing device is a mobile computing device.
19. The computing device of claim 9 , wherein the computing device is a slate of display-dominant device.
20. 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 by 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.
