    摘要： Embodiments presented herein relate to reducing visual artifacts on an electronic display caused by an intra-frame pause. To do so, the intra-frame pause may be divided into smaller intra-frame pause segments. The intra-frame pause segments may be applied to the display during different image frames and/or at different locations on the electronic display. For example, each intra-frame pause segment may be applied to a different location on the electronic display. In some embodiments, multiple intra-frame pause segments may be applied during a single image frame. In some embodiments, the intra-frame pause segments may be applied to various image frames and at various location on the electronic display according to a pattern. To reduce band flickering that may be caused by the different locations of the intra-frame pause segments, an emission duty of one or more rows of pixels of the display may be adjusted.

    摘要： The present disclosure relates to an electronic device that includes a display that has a plurality of scan lines. The display also includes a first data line that has a first number of pixels. The first data line forms a first number of crossovers with the plurality of scan lines. Additionally, the display includes a second data line that has a second number of pixels that is different than the first number of pixels. The second data line forms a second number of crossovers with the plurality of scan lines that is equal to the first number of crossovers.

    摘要： Systems and methods are provided for differential sensing (DS), difference-differential sensing (DDS), correlated double sampling (CDS), and/or programmable capacitor matching to reduce display panel sensing noise. An electronic device may include one or more processors and an electronic display. The one or more processors may generate image data and adjust the image data based at least in part on display sensing feedback. The electronic display may employ sensing circuitry that obtains the display sensing feedback at least in part by applying test data to a pixel of a column of an active area of the display and differentially senses an electrical value of the pixel in comparison to a reference signal from a different column. This reference signal may provide a common mode noise reference, which is removed by the differential sensing and thereby enhances a quality of the sensed electrical value of the pixel.

    摘要： A display may have rows and columns of pixels. Gate lines may be used to supply gate signals to rows of the pixels. Data lines may be used to supply data signals to columns of the pixels. The data lines may include alternating even and odd data lines. Data lines may be organized in pairs each of which includes one of the odd data lines and an adjacent one of the even data lines. Demultiplexer circuitry may be configured dynamically during data loading and pixel sensing operations. During data loading, data from display driver circuitry may be supplied, alternately to odd pairs of the data lines and even pairs of the data lines. During sensing, the demultiplexer circuitry may couple a pair of the even data lines to sensing circuitry in the display driver circuitry and then may couple a pair of the odd data lines to the sensing circuitry.
