An electronic device comprises a display and a controller. The controller is configured to provide a first frequency refresh rate to the display. The controller is also configured to generate a control signal configured to control emission of a light emitting diode of a display pixel of the display at a second frequency based on whether the first frequency refresh rate of the display is less than a predetermined threshold value.

Device and method for improved LED driving

A system may include an electronic display panel having pixels, where each pixel may emit light based on a respective programming signal. The system may include a memory storing a map. The processing circuitry may determine a function for each pixel from the map. The processing circuitry may determine a respective control signal based on the function and a target brightness level for each pixel to generate multiple control signals, where the respective control signal is used to generate the respective programming signal for each pixel. The processing circuitry may determine a scaling factor based at least in part on the first map and may scale at least a subset of the multiple control signals based at least in part on the scaling factor.

Configurable pixel uniformity compensation for OLED display non-uniformity compensation based on scaling factors

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.

Display with light-emitting diodes

Embodiments described herein generally take the form of an electronic device including a primary and secondary display; at least the secondary display is force-sensitive and further has its force-sensing circuitry in-plane with the display. The secondary display and force-sensing circuitry may be encapsulated between two glass layers that are bonded to one another by a frit. In some embodiments the force-sensing circuitry is formed from, or constitutes part of, the frit.

Computing device enclosure enclosing a display and force sensors

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.

Touch screen with perimeter touch electrodes

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.

Light sensing display

An electronic device may have a camera. The camera may capture still and moving images. A camera status indicator may be included in the electronic device. The camera status indicator may emit light to indicate when the camera is in use capturing video or other images. The camera status indicator may have multiple light-emitting devices such as light-emitting diodes or lasers. The light-emitting devices may have different colors. Clear encapsulant may cover the light-emitting devices. A white polymer wall or other light recycling structure may run along an outer peripheral edge of the encapsulant. A light diffusing coating layer may coat an outer surface of the clear encapsulant. Light reflections from the status indicator may be reduced in captured images.

Electronic device with camera status indicator

Force sensor and coplanar display

An electronic device comprises a controller. The controller is configured to provide a first signal to a display of the electronic device to turn off the display. The controller is also configured to provide a second signal to the display to alter a gate source voltage of a drive transistor coupled to a light emitting diode (LED) of a pixel of the display while the display is turned off.

Device and method for panel conditioning

Electronic devices and methods for compensating for aging or other effects in a display during a non-transmitting state (off state) of the display. Sensing may include emissive element sensing of the display and/or thin film transistor sensing of the display. Compensating for the effects may preserve or increase a uniformity of transmission of the display.

Display off-time sensing

Systems, methods, and devices for adjusting image display on an electronic display by predicting a temperature change of the electronic display due to heat-producing components near the display or due to changes in content. An electronic device may include an electronic display and processing circuitry. The electronic display may include pixels with behaviors that vary with temperature. As such, the processing circuitry may generate image data to send to the electronic display and adjust the image data or vary an operation of the electronic display based at least in part on a predicted temperature effect on at least part of the active area of the electronic display. The processing circuitry may determine the predicted temperature effect at least in part due to a first heat producing component or changes in content of the image data.
