Ocuity’s proprietary switching Polarisation Activated Microlens technology is based on novel micro optical arrays which have different optical properties depending on which polarisation of light is passed through them.

In 2D/3D displays, for light of one polarisation the microlenses are transparent and a 2D image is seen.  If the opposite polarisation is used, then the microlenses focus light to the left and the right eyes from alternate columns of pixels.  The brain fuses the two images to give the appearance of depth on the display. In Enhanced Brightness Displays, the lenses are oriented so that a pixel aperture is imaged to a super-bright viewing zone for both of the observer's eyes, which removes the effect of aperture ratio of the pixel and leads to the brightness enhancement effect. Scientific papers descibe Ocuity's technology in more detail.
