Patent ID: 11769441

Abstract:
A display module includes a display element, a light-guiding optical device, and a control unit configured to perform distortion correction including correction of a chromatic aberration of magnification. The light-guiding optical device is constituted of an optical system having non-axisymmetry in an up-and-down direction with respect to the imaging light entering the light-guiding optical device, and includes a first optical member having positive refractivity, a second optical member having positive refractivity, and a first reflection surface configured to reflect the imaging light toward a pupil position. The refractivity of the first optical member is greater than the refractivity of the second optical member. An abbe number of a constituent material of the first optical member is greater than an abbe number of a constituent material of the second optical member. The control unit performs distortion correction by a different distortion correction amount for each color light.
