Abstract: Display panels and encapsulation structures are described for OLED display panels, in particular. In an embodiment, a display panel includes a gate driver in panel (GIP) region, a GIP clock region within the GIP region, a pixel area region, and a VSSEL contact region laterally between an outer edge of the GIP region and the pixel area region. In some embodiments, structures are described in which capacitive coupling with the GIP clock region can be mitigated, and overlapping inorganic layers form a barrier to moisture outside of the pixel area region.

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.
