Abstract: A touch sensor panel operable within small form factor devices utilizes a plurality of discrete column electrodes arranged in a plurality of columns, and a plurality of continuous row electrodes arranged in a plurality of rows. Each column is divided into a plurality of regions, with each region formed from a plurality of electrically connected discrete column electrodes within that column. A scan plan includes a series of mutual capacitance scans wherein discrete column electrode(s) in all regions in all columns are sequentially stimulated, and AC signals indicative of mutual capacitance at certain the continuous row electrode(s) is measured. The scan plan includes a series of projection self-capacitance scans, wherein AC signals indicative of self-capacitance at a plurality of continuous row electrodes is measured for all rows, and AC signals indicative of self-capacitance at the discrete column electrodes in each region of all columns is measured.

Abstract: Touch sensor panels/screens can include negative temperature coefficient materials in the stack-up and routing traces with expanded areas to reduce thermal drift and minimize the detection of false touches. In some examples, the touch sensor panels/screens can include a plurality of touch electrodes in a first layer. In some examples, the sensor panels/screens can include one or more dielectric materials in a second layer, the one or more dielectric materials including a negative temperature coefficient material. In some examples, the touch sensor panels/screens can include a plurality of routing traces in a third layer, the plurality of routing traces routing the plurality of touch electrodes to a touch controller chip.

Abstract: Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.
