Abstract:
The embodiments herein use a corrector plate or a light field display in an AR/VR display device to compensate for sub-optimal collimation at the edge of the FOV. In one embodiment, the corrector plate is disposed between the collimator and the viewer so that the light at the edge of the FOV can be corrected so that the aberrations mentioned above do not occur. In another embodiment, rather than using a corrector plate, the AR/VR display device can include a light field display that can use color intensity to pre-distort emitted light to compensate for sub-optimal collimation at the edge of the FOV. In this manner, the AR/VR display device can mitigate aberrations or distortions as the user moves her eyes relative to the display device.
