Abstract: An electronic device may include an electronic display to display an image based on processed image data. The electronic device may also include image processing circuitry to generate the processed image data based on input image data and previously determined data stored in memory. The image processing circuitry may also operate according to real-time computing constraints. Cache memory may store the previously determined data in a provisioned section of the cache memory allotted to the image processing circuitry. Additionally, a controller may manage reading and writing of the previously determined data to the provisioned section of the cache memory.

Abstract: To reduce overall power consumption for an electronic display power management integrated circuit (PMIC), one of multiple electric power converters and/or electric power regulators may be selected based on an electrical load (e.g., due to the total brightness of the content displayed) on the electronic display at a given moment. In some embodiments, the PMIC may include a less efficient heavy load converter designed with high-current handling capability and a more efficient light load (e.g., low current) converter with lower current handling capability. A controller may dynamically select between the converters depending on a present load or an expected load on the electronic display.

Abstract: Systems, apparatuses, and methods for implementing a timestamp based display update mechanism. A display control unit includes a timestamp queue for storing timestamps, wherein each timestamp indicates when a corresponding frame configuration set should be fetched from memory. At pre-defined intervals, the display control unit may compare the timestamp of the topmost entry of the timestamp queue to a global timer value. If the timestamp is earlier than the global timer value, the display control unit may pop the timestamp entry and fetch the frame next configuration set from memory. The display control unit may then apply the updates of the frame configuration set to its pixel processing elements. After applying the updates, the display control unit may fetch and process the source pixel data and then drive the pixels of the next frame to the display.

Abstract: Methods and devices for reducing the power consumption of a frame buffer and timing controller of an electronic display are provided. By way of example, a method of operating an electronic display includes receiving image data from a processor of the electronic display, storing the image data to a buffer of the electronic display, reading the image data from the buffer to supply the image data to a column driver of the electronic display, determining whether an amount of image data stored in buffer is less than a threshold, and switching from reading the image data from the buffer to reading the image data directly from the processor when the amount of image data stored in buffer is less than the threshold.

Abstract: Systems, methods, and device are provided to provide inversion techniques for dynamic variable refresh rate electronic displays. One embodiment of the present disclosure describes An electronic display including a display panel that display images with varying refresh rates and a timing controller that receives image data from an image source, determines a counter value, and instructs a driver in the electronic display to apply a voltage to the display panel to write an image on the display panel, in which a negative voltage is applied when the counter value is positive and a positive voltage is applied when the counter value is less than or equal to zero. Additionally, the timing controller update the counter value based at least in part on duration the image is displayed on the display panel, wherein the counter value increases when the voltage is positive and decreases when the voltage is negative.

Abstract: Devices and methods for reducing and/or substantially eliminating pixel charge imbalance due to variable refresh rates are provided. By way of example, a method includes providing a first frame of image data via a processor to a plurality of pixels of the display during a first frame period corresponding to a first refresh rate, and providing a second frame of image data to the plurality of pixels of the display during a second frame period corresponding to a second refresh rate. The method further includes dividing the first frame period into a first frame sub-period and a second frame sub-period, and driving the plurality of pixels of the display with the first frame of image data during the first frame sub-period and the second frame sub-period.

Abstract: Devices and methods for providing an indication of an active frame start, while reducing a number of line buffers utilized by conventional systems are provided herein. By way of example, an electronic display panel may include a host device (e.g., a processor) that provides an indication of a pending active frame start. The indication may be provided at a predetermined and fixed time/line interval before the active frame start. Next, a timing controller of the display circuitry may generate a vertical start pulse during vertical blanking based upon the indication and the fixed time/line interval. The vertical start pulse may be used to drive multi-clock integrated row driver circuits.
