Abstract: Touch regions in a diamond configuration in a touch sensitive device are disclosed. Touch regions can include drive regions of display pixels to receive stimulation signals and sense regions of display pixels to send touch signals based on a touch or near touch. The drive regions and sense regions can be disposed diagonally adjacent to each other to form a diamond configuration. In an example diamond configuration, diagonal drive regions can be separate and unconnected from each other, while diagonal sense regions can be electrically connected to each other via their sense lines. The diagonal sense region connections can be in a forward diagonal direction, a backward diagonal direction, or a combination thereof. In an alternate example diamond configuration, diagonal drive regions can be electrically connected to each other via their drive lines, while diagonal sense regions can be electrically connected to each other via their sense lines. The diagonal drive and sense region connections can be in a forward diagonal direction, a backward diagonal direction, or combinations thereof. An exemplary touch sensitive device having a diamond configuration can be a touch screen.

Abstract: Touch sensitive displays are disclosed that can include circuitry that is segmented into multiple portions that can be independently operated. Touch sensitive display circuitry can be split in half with an upper portion and a lower portion that can each be independently operated. The separate circuitry portions can be used for performing display operations and for performing touch sensing operations. Display operations can be performed in one portion of the display while touch sensing operations are simultaneously performed in another portion of the display. Periodically, the operation being performed in a given portion of the display can be switched so as to alternatingly update that portion of the display and sense touch events in that region.

Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

Abstract: The present disclosure relates to one or more intermediate layers located on a surface of a cover material of an acoustic touch screen. In some examples, the one or more layers can include one or more intermediate layers. The one or more intermediate layers can include a first layer including a plurality of features and a second layer located between the first layer and the cover material. In a touch condition, the touch object can apply a force to the top surface of the acoustic touch sensor. The applied force can create one or more local bends causing the plurality of features to move closer to the cover material and causing one or more surface discontinuities in the cover material. The acoustic waves can undergo reflections (e.g., causing the signal to be attenuated) due to the discontinuities located in the path of the wave propagation.
