Abstract: Systems and methods for programming an electronic display in a double-row manner are provided. A system may include processing circuitry that generates image data and an electronic display that programs multiple rows of display pixels with different pixel data of the image data at the same time.

Abstract: Systems, methods, and devices described herein may implement a region-based refresh technique that reduces power consumption. The electronic device may include processing circuitry that compares a frame of image data with a previous frame of image data to identify row updates (e.g., changes). The electronic device may instruct the electronic display to update the rows to display the changed image content. For example, the electronic display may include gate-in-panel circuits that enable respective rows to receive a portion of the image data. Each gate-in-panel circuit may include a switch that selectively couple components of the gate-in-panel circuits, and moreover, selectively couple the gate-in-panel circuit to the row. If the image data for the respective row is changing, the switch may be toggled to a closed position to couple the components and drive a gate signal onto the row, thereby updating the row with the changed image content.

A touch system may compensate touch scan data to reduce the noise based on an estimated amount of switching-based display-touch crosstalk (switching DTX). Using the compensated touch scan data, the touch system may determine the proximity of a capacitive object to at least one touch sense region of the electronic display with improved signal to noise ratio.

Abstract: An electronic device may include an electronic display to display frames of image data and processing circuitry to determine a display strain transition event of the electronic display and change a refresh rate of the electronic display based on the determination of the display strain transition event. The electronic device may temporarily increase the refresh rate based on determining that the display strain transition event includes folding or unfolding the electronic display. The electronic device may sequence down the refresh rate to a lower refresh rate after a period of time. As such, perceivable image artifacts in displayed image content caused by folding or unfolding the electronic display may be reduced or eliminated.

Abstract: An electronic device may include an electronic display having multiple display pixels that display an image based on dithered image data. The electronic device may also include image processing circuitry that generates the dithered image data based on input image data and a threshold gray level that is greater than one. Generating the dithered image data may include replacing each gray level of the input image data that is less than the threshold gray level with either a zero gray level or the threshold gray level according to a dither pattern.

Abstract: A display may overlap a sensor such as a camera or ambient light sensor. A portion of the display that overlaps the sensor may be modified to increase transparency relative to the remaining portion of the display. The modified portion of the display may have pixel islands that conform to a regular grid pattern of the remaining portion of the display. One or more gate lines and/or one or more data lines may pass through the modified portion of the display without connecting to any subpixels in the modified portion of the display. An opaque pixel definition layer may include some openings that are aligned with opaque masking layer openings to allow on-axis light to pass through to a sensor and some openings that are offset relative to respective opaque masking layer openings to allow off-axis light to pass through to the sensor.

An electronic display may include an electronic display panel with lines and columns of display pixels. Each column of display pixels may be coupled to a respective data line. Display driver circuitry may adjust image data associated with the display pixels to account for coupling between the display pixels and the respective data lines.

Abstract: Display pixels of an electronic display may exhibit front-of-screen distortions when high spatial frequency image data is applied on the electronic display panel. The high spatial frequency may generate voltage ripple on a storage capacitor of pixel driving circuitry, causing mismatch between luminance of a first subpixel on an odd-numbered row and a corresponding subpixel on an even-numbered row. This odd-even row mismatch may be compensated via mismatch compensation circuitry. The mismatch compensation circuitry may include an odd subpixel compensation LUT and an even subpixel compensation LUT. The odd subpixel compensation LUT may output odd subpixel compensation values and the even subpixel compensation LUT may output even subpixel compensation values. The multiplexer may combine the odd subpixel compensation values and the even subpixel compensation values with input image data to generate compensated subpixel data, which may reduce or eliminate the odd-even row mismatch.

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 and methods described herein may utilize a non-linear scaling relationship to scale brightness of selective portions of the display in a manner that reduces or eliminates perceivable banding effects. By non-linearly controlling changes in brightness of the display, a viewer may perceive a more uniform, linear dimming towards the relatively dimmer region without perceiving banding, leading to improved user experience when viewing the electronic display.

Abstract: In a display characterized by regions with different pixel responses due, for example, to local pixel density variation, voltage-to-luminance matching may be non-universal. Therefore, in order to avoid visual artifacts that may hinder a desired visualization of displayed content, it may be advantageous to compensate the different gamma responses. In some cases, such as with electronic devices having a single pixel density across the display, optical calibration may be performed to determine voltage-to-luminance matching. However, in electronic devices with local pixel density variations, it may be disadvantageous to perform optical calibrations for each region with a different pixel density. Instead of using two distinct gamma curves which may include dedicated optical calibration, a global nonlinear scaler (GNLS) compensation may be applied.

Abstract: Embodiments herein provide various apparatuses and techniques to efficiently mitigate front-of-screen (FoS) artifacts that may occur due to voltage fluctuations due to alternating current (AC) or direct current (DC) mechanisms that may occur in a variety of pixel types. In one embodiment, emission profile awareness circuitry may be implemented to mitigate for FoS artifacts due to DC mechanisms. Two-dimensional (2D) digital compensation circuitry may address the DC portion of the voltage fluctuations by accounting for an emission profile applied to content displayed on an electronic display. In some embodiments, the 2D digital compensation circuitry may compensate for the AC portion of the voltage fluctuations by duplicating the AC voltage fluctuations via voltage error subtraction circuitry and voltage error accumulation circuitry.

Abstract: This disclosure provide various techniques for tracking emission profiles on an electronic display. An emission profile may be applied to the electronic display in order to illuminate certain pixels and deactivate (e.g., turn off) certain pixels in the electronic display to facilitate refreshing (e.g., programming with new image data) the deactivated pixels. A real-time row-based average pixel level or average pixel luminance calculation architecture may track the one or more EM profiles to accurately model EM profile behavior, which may enable accurate calculation of the average pixel level or average pixel luminance of the electronic display at any one point in time. The accurate average pixel level or average pixel luminance calculations effectuated by the EM profile tracking may be used to reduce the IR drop, improve real-time peak-luminance control, and improve the performance of under-display sensors, among other advantages.

The electronic device may also include compensation circuitry that applies a compensation to the activation signal and/or to the image data based on the comparisons between the characteristic responses and the baselines.
