Operating multiple functions in a display of an electronic device
First Claim
1. A method for operating a system that includes a display, a force sensing device, and a touch sensing device, the force sensing and touch sensing devices each sharing at least a portion of an area of the display, the method comprising:
- performing a refresh operation on at least a portion of pixels in the display during a pixel refresh time period;
performing a force sensing operation in the force sensing device during a first time period that occurs during the pixel refresh time period; and
performing a touch sensing operation in the touch sensing device during a second time period that occurs during the pixel refresh time period;
wherein;
the first time period and the second time period are non-overlapping time periods.

Abstract
A system can include a display, a first device, and a second device all operatively connected to a controller. The first and second devices each use or share at least a portion of the display area. The controller is adapted to transmit during a pixel refresh time period of the display a first signal that is received by the first device. The first sync signal indicates a first time period in which a first operation can be performed in the first device. The controller is also adapted to transmit a second sync signal that is received by the second device indicating a second time period in which a second operation can be performed in the second device. The second time period can be during the pixel refresh time period or outside of the pixel refresh time period.
