Display with light transmitting windows

A display having an array of pixels configured to display images, the display comprising:

• a substrate;
• thin-film circuitry on the substrate that comprises an array of light-emitting diodes, wherein the thin-film circuitry includes a cathode layer that overlaps the array of light-emitting diodes and wherein each light-emitting diode includes an anode and includes emissive material interposed between the anode of that light-emitting diode and the cathode layer;
• and
• electrical components, wherein the substrate is interposed between the electrical components and the thin-film circuitry, wherein the thin-film circuitry is configured to form light transmitting windows interspersed with at least a portion of the array of pixels, wherein each of the light transmitting windows is aligned with a corresponding one of the electrical components, wherein the windows have antireflection layers, wherein the antireflection layers include at least one inorganic dielectric layer interposed between the cathode layer and the emissive material in the windows.

A display, comprising:

• a substrate;
• thin-film circuitry on the substrate that comprises an array of light-emitting diodes, wherein the thin-film circuitry includes a cathode layer that overlaps the array of light-emitting diodes and wherein each light-emitting diode includes an anode and includes emissive material interposed between the anode of that light-emitting diode and the cathode layer;
• and
• an array of light sensors, wherein the substrate is interposed between the array of light sensors and the thin-film circuitry and wherein the thin-film circuitry is configured to form light transmitting windows each of which is aligned with a corresponding one of the light sensors, wherein the cathode layer has a first thickness in a first region of the thin-film circuitry that overlaps the array of light sensors and wherein the cathode layer has a second thickness that is greater than the first thickness in a second region of the thin-film circuitry that overlaps the array of light-emitting diodes and does not overlap the array of light sensors.
