Abstract: An electronic device includes a flexible substrate. The flexible substrate includes a first portion having a plurality of first conductive lines formed thereon, a second portion having a plurality of second conductive lines formed thereon, and an intermediate portion mechanically coupling the first portion to the second portion. The intermediate portion is configured to permit folding so that the first and second portions can be arranged back-to-back or face-to-face such that plurality of the second conductive lines and plurality of first conductive lines are oriented so as to cross one another to thereby form a capacitive sensing panel. A single connector is mechanically coupled to the first portion or the second portion, and electrically coupled to the first portion and the second portion but not electrically coupling the first portion to the second portion.

Abstract: A touch screen device is configured with rows of conductors capable of receiving wireless signals from a stylus. When the stylus touches the touch screen, the stylus emits multiple wireless signals in different directions. The conductors receiving the emitted wireless signals provide the signals to circuitry that filters, amplifies, and digitizes the wireless signals, as received at each conductor. The magnitude of each conductor's received wireless signal is computed, and the computed magnitudes are used to determine the location of the stylus on the touch screen surface. The stylus is assumed to be closer to conductors receiving stronger signals than those receiving weaker signals.

Abstract: An in-cell touchscreen panel includes columns of transmit electrodes and rows of sensing electrodes, wherein each row of sensing electrodes comprises a first subset of sensing electrodes coupled to control circuitry via a first subset of receiving traces and a second subset of sensing electrodes coupled to the control circuitry via a second subset of receiving traces. To enable multi-touch functionality, the in-cell touchscreen panel operates in a scanning mode where capacitance is measured at each node where the sensing electrodes intersect the transmit electrodes. During the scanning mode, the control circuitry senses the first and second subsets of receiving traces while applying drive signals to pairs of transmit electrodes. After a drive signal has been applied to each of the transmit electrodes, each of the nodes are measured to detect a capacitance. This capacitance is indicative of a user touch on the in-cell touchscreen panel.

Abstract: A touch screen controller (TSC) performs mutual capacitance sensing to acquire touch strength values from a touch matrix formed by capacitively intersecting drive and sense lines. For each sense line, the TSC sums the touch strength values associated therewith to form an emulated value for that sense line, and applies a weighting thereto, the weighting based upon a position of that sense line compared to a location on the touch matrix adjacent which a user's ear is expected to be placed. For each drive line, the TSC sums the touch strength values associated therewith to form an emulated value for that drive line, and applies a weighting thereto, the weighting based upon a position of that drive line compared to the location on the touch matrix adjacent which the user's ear is expected to be placed. The TSC determines presence of the user's based upon the emulated values.

Abstract: A touch screen controller includes driving circuitry coupled to a conductive line through a resistance and drives that conductive line with a driving signal passed through the resistance at a drive frequency. Sensing circuitry is coupled to that conductive line and senses a voltage at that conductive line, the voltage being a function of a capacitance seen by that conductive line. Analog to digital conversion circuitry is coupled to the sensing circuitry and samples the sensed voltage at a sampling frequency to produce samples. Processing circuitry is coupled to the analog to digital conversion circuitry and directly calculates a tangent of a phase shift of the voltage due to the resistance and the capacitance from the samples, and determines a self touch value for that conductive line as a function of the tangent of the phase shift of the voltage.

Abstract: Disclosed herein is a touch screen controller for controlling touch sensing in a touch screen display, the touch screen display having a display layer controlled as a function of horizontal sync and vertical sync signals and a capacitive touch array comprised of drive lines and sense lines. The touch screen controller includes a driver and control circuitry. The control circuitry is configured to cause the driver to generate a driving signal on the drive lines during assertion of the horizontal sync signal, and cause the driver to generate the driving signal on the drive lines during assertion of the vertical sync signal. Analog touch sensing circuitry is configured to generate analog touch data as a function of signals on the sense lines resulting from generation of the drive signal on the drive lines.

Abstract: A touch screen controller includes drive circuitry driving force lines with a force signal in a touch data sensing mode and not driving the force lines in a noise sensing mode, sense circuitry sensing touch data at the sense lines in the touch data sensing mode and sensing noise data at the sense lines during the noise sensing mode. Processing circuitry: a) samples the noise data, b) performs trigonometric manipulations of the noise data to produce imaginary noise data and real noise data, and c) determines a noise magnitude value of the noise data as a function of the imaginary noise data and the real noise data. In the noise sensing mode, (a)-(c) are performed for each of a plurality of possible sampling frequencies to be used in the touch data sensing mode in order to determine which sampling frequency is to be used in the touch data sensing mode.

A touch screen includes a touch screen panel (mounted on top of the video display panel) and a touch panel control and sense circuit configured to operate the touch screen panel in a self-capacitance mode. The touch panel control and sense circuit includes sense drive circuits configured to generate sense drive signals for application to sense lines of the touch screen panel. A controller controls actuation of the sense drive circuits so that the sense drive signals are synchronized to the display on condition. In an implementation, the leading edges of the sense drive signals are synchronized to the display on condition. In another implementation, a window is synchronized to the display on condition and the leading edges of the sense drive signals exhibit jitter within the window.
