    Abstract: A display may have an array of pixels each of which has a light-emitting diode such as an organic light-emitting diode. A drive transistor and an emission transistor may be coupled in series with the light-emitting diode of each pixel between a positive power supply and a ground power supply. The pixels may include first and second switching transistors. A data storage capacitor may be coupled between a gate and source of the drive transistor in each pixel. Signal lines may be provided in columns of pixels to route signals such as data signals, sensed drive currents from the drive transistors, and predetermined voltages between display driver circuitry and the pixels. The switching transistors, emission transistors, and drive transistors may include semiconducting-oxide transistors and silicon transistors and may be n-channel transistors or p-channel transistors.

    Abstract: A touch screen may be formed from a display and perimeter touch electrodes. Touches detected at one or more of the perimeter touch electrodes can be imputed to touch on a region of the display of the touch screen adjacent to the perimeter touch electrodes. In some examples, the perimeter touch electrodes comprise segmented frit metal arranged around the perimeter of the display (e.g., frit metal used to encapsulate the display). In some examples, the perimeter touch electrodes can be coupled to one or more touch sensing circuits via switching circuitry. In some examples, the switching circuitry can be operated based on control signals shared with the display circuitry.

    Abstract: A display may have an array of pixels. The pixels may contain light-emitting diodes. When it is desired to use the display to operate as a light sensor, some of the light-emitting diodes may be forward biased to emit light while some of the light-emitting diodes are reversed biased to detect the emitted light after the emitted light has reflected from an external object. During light sensing operations, one or more areas of the display may be temporarily deactivated so that the light-sensing pixels may measure the reflected light. Vertical lines may serve both as data loading lines and as current sensing lines. Currents may be sensed during drive transistor current compensation and during light sensing. The vertical lines may load signals into the pixels that forward bias the light-emitting diodes to emit light when it is desired to display images for a user.
