Abstract: A display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap an optical sensor. Each high-transmittance area may be devoid of thin-film transistors and other display components. To improve transmission while maintaining satisfactory touch sensing performance, one or more segments of the touch sensor metal in the pixel removal region may have a reduced width relative to the touch sensor metal in the full pixel density region and/or one or more segments of the touch sensor metal in the pixel removal region may be omitted relative to the touch sensor metal in the full pixel density region. To mitigate a different appearance between the pixel removal region and the full pixel density region at off-axis viewing angles, the position of the touch sensor metal in the pixel removal region may be tuned.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap the optical sensor. To mitigate reflectance mismatch between the full pixel density region and the pixel removal region, the pixel removal region may include a transition region at one or more edges. In the transition region, one or more components may have a gradual density change between the full pixel density region and a central portion of the pixel removal region. Components that may have a changing density in the transition region include dummy thin-film transistor sub-pixels, dummy anodes, a cathode layer, and a touch sensor metal layer. The transition region may also include anodes that gradually change shape and/or size.

Abstract: 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. This allows for the thin-film transistor sub-pixels to be grouped adjacent to the central area of the active area, leaving room along an edge of the active area to accommodate one or more additional display components such as gate driver circuitry or fanout portions of data lines.
