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 light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To mitigate artifacts caused by a light emitter operating through a display, the display may have a higher density of thin-film transistor sub-pixels than emissive sub-pixels. This allows for a region in the display to include emissive sub-pixels but be free of thin-film transistor sub-pixels. The light emitter may operate through this region in the display. Additionally, to reduce the amount of space occupied in the inactive area of a display by gate driver circuitry, at least a portion of the gate driver circuitry may be positioned in the active area of the display. To accommodate the gate driver circuitry, emissive sub-pixels may be laterally shifted relative to corresponding thin-film transistor sub-pixels.
