    Abstract: An electronic device may include a display. The display may be formed by an array of light-emitting diodes mounted to the surface of a substrate. The substrate may be a silicon substrate. Circuitry may be located in spaces between the light-emitting diodes. Circuitry may also be located on the rear surface of the silicon substrate and may be coupled to the array of light-emitting diodes using through-silicon vias. The circuitry may include integrated circuits and other components that are attached to the substrate and may include transistors and other circuitry formed within the silicon substrate. Touch sensor electrodes, light sensors, and other components may be located in the spaces between the light-emitting diodes. The substrate may be formed from a transparent material that allows image light to reach a lens and image sensor mounted below the substrate.

    Abstract: An electronic device has a display and has a touch sensitive bezel surrounding the display. Areas on the bezel are designated for controls used to operate the electronic device. Visual guides corresponding to the controls are displayed on the display adjacent the areas of the bezel designated for the controls. Touch data is generated by the bezel when a user touches an area of the bezel. The device determines which of the controls has been selected based on which designated area is associated with the touch data from the bezel. The device then initiates the determined control. The device can have a sensor for determining the orientation of the device. Based on the orientation, the device can alter the areas designated on the bezel for the controls and can alter the location of the visual guides for the display so that they match the altered areas on the bezel.

    Abstract: Measuring an effect of body capacitance in a touch sensitive device is disclosed. This effect can be caused by poor grounding of a user or other objects touching the device or of the device itself. The device can operate in a stray capacitance mode to measure a body capacitance effect and in a normal mode to detect a touch on the device. During the stray capacitance mode, the device can obtain a body capacitance measurement from the device. During the normal mode, the device can obtain a touch measurement from the device. The device can calculate a body capacitance factor based on a ratio between the body capacitance measurement and the touch measurement and use the body capacitance factor to compensate for erroneous or distorted touch output values from the device. Various components of the device can be switchably configured according to the particular mode.

    Abstract: Error compensation of a touch sensing signal is provided. A touch screen can include a drive region that can be driven by a drive signal, and a sense region that can output a sense signal that includes information of a first amount of touch on or near the touch screen and information of a first amount of error. The first amount of touch can be based on the drive signal. The touch screen can include a compensation sensor that can output a compensation signal that includes information of a second amount of error, and an error compensator that can compensate for the first amount of error in the sense signal based on the second amount of error.

    Abstract: Rotary encoders suitable for inclusion within small form factor devices (e.g., as input devices to small form factor electronic devices) are disclosed. In one aspect, a light source can illuminate a pattern on a rotatable shaft in order to reflect the pattern onto an array of optical sensors. Each optical sensor from the array of optical sensors can be polled at the same time to yield a snapshot vector. The snapshot vector can be projected onto a subspace spanned by two vectors selected in part on the pattern of the rotatable shaft and the distance separating the shaft and array. The resulting projection can be used to determine error and phase of the reflected pattern across the array of optical sensors. The phase of the reflected pattern can correlate to rotation of the shaft.
