Field curvature corrected display

A head mounted display (HMD) comprising:

• a field curvature corrected (FC) display configured to correct for field curvature in an image that is output to an eye of a user of the HMD, the FC display comprising:
• a electronic display panel that output image light;
• a linear polarizer configured to linearly polarize the image light;
• and
• a pancake lens assembly, the pancake lens assembly comprising:
• a first optical element including a first waveplate surface and a first mirrored surface, the first waveplate surface is a quarter waveplate configured to receive light from the linear polarizer and shift a polarization of the image light, the first mirrored surface is a partially reflective mirror that is configured to transmit a portion of the image light, and
• a second optical element including a second waveplate surface and a second mirrored surface, the second waveplate surface is a quarter waveplate configured to receive the image light from the first optical element and shift a polarization of the image light transmitted by the second waveplate surface, the second mirrored surface is a polarized reflector, the second mirrored surface is configured to reflect image light of a first polarization toward the second waveplate surface and transmit image light of a second polarization that is corrected for field curvature to an exit pupil of the HIVID corresponding to a location of an eye of a user of the HMD.

A head mounted display (HMD) comprising:

• a field curvature corrected (FC) display configured to correct for field curvature in an image that is output to an eye of a user of the HIVID, the FC display comprising:
• a display block configured to output image light;
• and
• an optics block configured to optically direct image light corrected for field curvature to an exit pupil of the HIVID corresponding to a location of an eye of a user of the HIVID, the optics block including a first and second lens, the first lens configured to receive the image light from the display block and the second lens configured to optically direct the image light output from the first lens to an exit pupil of the HIVID corresponding to a location of an eye of a user of the HIVID.
