Hybrid Folded Birdbath Display

An electronic device comprising:

• a display panel configured to emit light;
• a first optical wedge having a first surface and a second surface opposite the first surface;
• a second optical wedge having a third surface at the second surface;
• a third optical wedge having a fourth surface at the first surface;
• an air gap defined between a portion of the first surface and a portion of the fourth surface;
• a reflective polarizer sandwiched between the second surface and the third surface;
• a partial reflector layered on the first surface within the air gap;
• and
• a quarter waveplate layered on the partial reflector within the air gap, wherein the reflective polarizer, the partial reflector, and the quarter waveplate are configured to redirect the light.

An electronic device comprising:

• a display panel configured to emit light;
• a first optical wedge configured to reflect the light twice via total internal reflection;
• a second optical wedge having a curved surface separated from the first optical wedge by an air gap;
• and
• a partial reflector layered on the curved surface within the air gap, the partial reflector being configured to receive the light after the light has been reflected by the first optical wedge twice via total internal reflection, the partial reflector being configured to reflect the light towards an eye box through the first optical wedge.
