Patent number: 10088951Abstract: Embodiments described herein include an input device, a display device having a capacitive sensing device, a processing system and a method for detecting presence of an input object using a capacitive sensing device. In one embodiment, an input device includes a plurality of sensor electrodes arranged in a planar matrix array. Each sensor electrode is coupled to unique routing trace and has an identical geometric plan form that is symmetrical about a center of area of the sensor electrode. The geometric plan form of each sensor electrode includes core and a plurality of protrusions extending outward from the core. The protrusions are configured to overlap with protrusions extending outward from each adjacent sensor electrode of the matrix array.Type: GrantFiled: June 25, 2015Date of Patent: October 2, 2018Assignee: SYNAPTICS INCORPORATEDInventors: Petr Shepelev, Christopher A. Ludden, Jeffrey Lukanc, Stephen L. Morein, Greg P. Semeraro, Joseph Kurth Reynolds

Patent number: 9552089Abstract: An electrode matrix that is used for capacitive sensing may be integrated into a display panel of an input device. In one embodiment, source drivers may be mounted on the display panel which drive the display signals and capacitive sensing signals into the display panel. In one embodiment, the capacitive sensing signals may be routed on traces or lines that are interleaved on the same layer as the source lines used for setting a voltage on the pixels in the display panel during display updating. Using the interleaved traces, the source drivers may drive the capacitive sensing signals in parallel to a plurality of the electrodes in the matrix in a predefined pattern that spans one or more sensing cycles.Type: GrantFiled: December 20, 2013Date of Patent: January 24, 2017Assignee: SYNAPTICS INCORPORATEDInventors: Jeffrey Lukanc, Stephen L. Morein, Christopher A. Ludden, Greg P. Semeraro, Joseph Kurth Reynolds, Petr Shepelev, Thomas Mackin
