    Abstract: In an embodiment, an electronic device includes an electronic display. The electronic display provides a programmable latency period in response to receiving a first image frame corresponding to first image frame data. The electronic display also displays the first image frame after the programmable latency period and during display of the first image frame, receives a second image frame corresponding to second image frame data. The electronic display also repeats display of the first image frame in response to receiving the second image frame.

    IPC: G06F1/16

    Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed in a display panel having a single substrate or an array of display panel tiles. The display panel has inwardly facing display panel contacts that mate with corresponding outwardly facing interconnect substrate contacts on an interconnect substrate. The interconnect substrate may have areas with compound curvature that are overlapped by the display panel. To enhance flexibility of the interconnect substrate, the interconnect substrate may have flexibility enhancement openings and/or may be formed from a material with a low elastic modulus such as silicone or other elastomeric material.

    Abstract: 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.

    Abstract: Electronic devices, storage medium containing instructions, and methods pertain to determining a target boosted threshold voltage level based at least in part on a target emission threshold voltage level. Using the determined target boosted threshold voltage level, a light emitting diode (LED)-controlling transistor is submitted to voltage stress to boost a threshold voltage of the transistor to the target boosted threshold voltage level during a first portion of a refresh period between first and second emission periods. During a second portion of the refresh period, the voltage stress is de-asserted to settle the threshold voltage to a target emission threshold voltage level for the second emission period. After the voltage is settled, the LED-controlling transistor is driven based at least in part on the target emission threshold voltage level.

    Abstract: An electronic device may have a display such as an organic light-emitting diode display. Electronic devices may also include a number of sensors such as accelerometers and gaze detection sensors. A graphics processing unit (GPU) may render digital pixel values for pixels in the device display. Frames (F2) with long rendering times may cause latency. To reduce latency, an image frame may be displayed for an extended period of time (68) to wait for the subsequent frame (F2) to finish rendering. Once the subsequent image frame (F2) has finished rendering, the subsequent image frame may be displayed without delay. To increase the lifespan of the display, variable persistence may be used. Sensor data and other factors may be used to dynamically determine persistence for minimal motion blur and maximum display lifespan. Sensor data may also be used to determine refresh rates for different portions of the display.
