Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The display may include transistors with gate conductors, a first planarization layer formed over the gate conductors, one or more contacts formed in a first source-drain layer within the first planarization layer, a second planarization layer formed on the first planarization layer, one or more data lines formed in a second source-drain layer within the second planarization layer, a third planarization layer formed on the second planarization layer, and a data line shielding structure formed at least partly in a third source-drain layer within the third planarization layer. The data line shielding structure may be a routing line, a blanket layer, a mesh layer formed in one or more metal layers, and/or a data line covering another data line.

Abstract: The present disclosure provides a semiconductor device and a method of manufacturing the semiconductor device. The semiconductor device includes channel members disposed over a substrate, a gate structure engaging the channel members, and an epitaxial feature adjacent the channel members. At least one of the channel members has an end portion in physical contact with an outer portion of the epitaxial feature. The end portion of the at least one of the channel members includes a first dopant of a first concentration. The outer portion of the epitaxial feature includes a second dopant of a second concentration. The first concentration is higher than the second concentration.

Abstract: An electronic device may have a display with an active area configured to display images and an inactive area that is free of pixels and that does not display images. Touch sensor sense lines may have portions located in the active area and portions located in the inactive area. The active and inactive areas may be characterized by respective reflectivity values. To match the reflectivities of the active and inactive areas and thereby avoid undesired visually distinguishable differences in the appearances of these areas, the touch sensor circuitry in the inactive areas may be configured to match the reflectivity values of the active and inactive areas. Sense line portions in the inactive area may have metal traces of enhanced reflectivity and/or uneven surface topology to enhance ambient light reflections through a circular polarizer that overlaps the active and inactive areas.

Abstract: A flexible display in a foldable electronic device may have a display cover layer and display panel that bend around a bend axis. The display panel may have an array of pixels configured to display an image through the display cover layer. The pixels may be formed from thin-film display circuitry that is supported by a flexible display panel substrate. The flexible substrate may be supported by a display support plate that bends about the bend axis. The display may be configured to allow attachment of the display panel substrate to the display support plate while helping to prevent undesired localized deformation of the thin-film display circuitry.

Abstract: An electronic device may include multiple display layers. The display layers may include a matching layer implemented using multiple graded index of refraction sublayers to help minimize reflections. The matching layer may include a first sublayer having a monotonically increasing index of refraction, a second (reverse matching) sublayer having a monotonically decreasing index of refraction, and a third sublayer having a monotonically increasing index of refraction. The second reverse matching sublayer may serve to induce an optical path difference that results in destructive inference at one or more specific wavelengths. The thickness of the reverse matching sublayer may be tuned to center the destructive interference at the desired wavelength(s). If desired, multiple matching layers each having their own reverse matching layers may be stacked on top of one another to provide reflectance suppression at multiple wavelengths.
