Abstract
An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The display may include ray tracing circuitry that is configured to, using ray tracing, a three-dimensional image, and deflection measurements for the array of pixels, output a display calibration map that includes, for each pixel in the array of pixels, a corresponding location on a two-dimensional image. The display may also include pixel mapping circuitry configured to, using the display calibration map from the ray tracing circuitry, map the two-dimensional image to respective pixels on the array of pixels to obtain pixel data for the array of pixels.
