Abstract: A mobile electronic device includes a display having a pixel and processing circuitry separate from but communicatively coupled to the display. The processing circuitry prepares image data to send to the pixel and adjusts the image data to compensate for operational variations of the display based on feedback received from the display that describes a present operational behavior of the pixel. The mobile electronic device also includes additional electronic components that affect the present operational behavior of the pixel depending on present operational behavior of the additional electronic components.

Abstract: An electronic display includes an active area including multiple pixels. The electronic display also includes a first row driver set including a first column of row drivers and a second column of row drivers. A first active row driver in the first column of row drivers drives a first portion of the multiple pixels, and a first spare row driver in the second column of row drivers is in an inactive state. The electronic display also includes a second row driver set including a third column of row drivers and a fourth column of row drivers. A third active row driver in the third column of row drivers drives a second portion of the multiple pixels, and a second spare row driver in the fourth column of row drivers is inactive.

Abstract: 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.

Abstract: Electronic devices and methods for compensating for noise in a display that includes sensing a current in a sensing channel of the display. Compensating for the noise also includes sensing an observation current from noise in an observation channel of the display and scaling the observation current to generate a scaled observation current. The scaled observation current is subtracted from the sense current to generate a compensated output. The compensated output is used to drive compensation operations of the display based at least in part on the compensated output to reduce effects of the noise.
