Curved electronic display element
A head-mounted display (HMD) including an electronic display. The electronic display is configured to output image light. The electronic display includes a display panel including a surface configured to emit image light, and a fiber optic taper. The fiber optic taper includes a mounting surface and a display surface. The mounting surface is formed to, and affixed to, the surface of the display panel to receive the image light from the display panel. The display surface has a shape configured to output the image light corrected for optical distortion in the image light received from the cylindrically curved display panel. The HMD includes an optics block configured to optically direct the corrected image light to an exit pupil of the HMD corresponding to a location of an eye of a user of the HMD.
