Abstract: A non-transitory computer-readable storage medium comprising instructions stored thereon. When executed by at least one processor, the instructions ban be configured to cause a computing device to, in response to an instruction to transition from a first refresh rate to a second refresh rate, modify a transitional frame. The modifying the transitional frame can include refreshing a first row in a display with a first adjustment to a peak signal of at least one pixel in the first row, and refreshing a second row in the display with a second adjustment to a peak signal of at least one pixel in the second row, the second row being refreshed after the second row, the second adjustment being greater than the first adjustment.

Abstract: A computing device includes a display panel having a first end and a second end, a sensor, and a processing circuitry. Tire display panel includes a matrix of pixels and defines an aperture surrounded by pixels of the matrix of pixels but that does not include pixels of the matrix of pixels. A length of the aperture parallel to an axis connecting the first end and the second end is greater than a length of the aperture perpendicular to the axis. The sensor is configured to capture light that passes through the aperture. The processing circuitry, disposed proximal to the second end, is configured to output control signals to pixels of the matrix of pixels.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for driving a display with an array of light-emitting pixels. The pixels are arranged in a plurality of rows. The array includes two or more independently drivable areas. Each area includes two or more adjacent rows. The method includes, during an image frame, while operating in a first mode of operation, activating a first shift register circuit addressing only rows of pixels in a first area of the independently drivable areas. Activating the first register circuit illuminates one or more pixels in the first area. The method also includes, during the image frame, while operating in the first mode of operation, deactivating a second shift register circuit addressing only rows of pixels in a second area of the independently drivable areas. Deactivating the second register circuit maintains every pixel in the second area unilluminated during the image frame.

Abstract: A method for driving an organic light emitting diode display having a first plurality of pixel lines having a first pixel density and a second plurality of pixel lines having a second pixel density higher than the first pixel density, the method including driving the first and second plurality of pixel lines with corresponding drive signals at a frame rate at which frames are displayed, where during each of the frames the drive signals have a pixel on time during which pixels in the pixel lines driven by the drive signals emit light and a pixel off time during which pixels in the pixel lines driven by the drive signals are dark, where the pixel on times and the pixel off times are varied between the drive signals to reduce variations in luminance.

Abstract: A display device includes subpixels of a first, second, and third colors, scan lines, and column lines. The subpixels are arranged in an array of rows and columns, with each subpixel in a column being electrically connected to a same column line. Each subpixels in a column is configured for receiving electronic scan signals that control a light output from an emissive element of the subpixel from a scan line and from the column line connected to the subpixel. One or more line drivers provide the electronic scan signals, during a time period for rendering a frame, to subpixels in a first set of columns first to subpixels of the first color and then to the subpixels of the third color and to subpixels in a second set of columns first to subpixels of the third color and then to the subpixels of the first color.

Abstract: A method can include determining that a first frame for display on an emissive display meets a low encoded intensity condition; based on the determination that the first frame meets the low encoded intensity condition, disabling refresh rate transitions when displaying multiple frames on the emissive display; while the refresh rate transitions are disabled, maintaining a refresh rate while changing a graphic intensity; determining that a second frame does not meet the low encoded intensity condition; based on the determination that the second frame does not meet the low encoded intensity condition, enabling refresh rate transitions when displaying multiple frames on the emissive display; and while the refresh rate transitions are enabled, changing the refresh rate for the emissive display based on the graphic intensity changing.

Abstract: Rendering images on an active area of an OLED includes rendering images on the active area of the display panel with a plurality of different frame rates. For a plurality of the different frame rates having a frame rate that matches or is above a threshold frame rate, an image refresh operation is performed once per frame period and a self-refresh operation is not performed during the frame period. When rendering images on the active area, for at least one of the different frame rates having a frame rate that is lower than the threshold frame rate, an image refresh operation is performed once per frame period and a self-refresh operation is performed at least once during the frame period.

Abstract: Techniques to provide uniform luminance across a computing device display, such as an active matrix organic light emitting diode (AMOLED) display. In some examples, a computing device display may include a hole within the active area of the display that may be used for a camera, a button or some other function. The hole may result in a non-uniform voltage drop in a power supply mesh in regions of the active area near the hole. The power supply mesh may provide electrical energy to elements of the display. The techniques of this disclosure include portions of the power supply mesh that are not connected to the voltage supply bus to ensure a uniform voltage drop across the active area of the display.

Abstract: A display includes subpixel emissive areas of first, second, and third colors arranged in an array that includes rows and columns. The display also includes scan lines, column lines, and electronic subpixel circuits arranged in the array, with each subpixel circuit in a column of the array being electrically connected to a same column line and each electronic subpixel circuit configured for receiving electronic signals from a scan line and from a column line and for converting the received signals into a current signal provided to one of the subpixel emissive areas to drive light emission from the subpixel emissive area. The display further includes multiplexer (MUX) switches, where every other column line of the columns lines is configured to be connected to at least two outputs from a column line driver through the MUX switches.
