摘要
Eyeglasses (8) incorporating broad-band quarter-wave retardation plates (1), where the angle between the plate's fast axis (2) and the electric field vector (4) of the incident plane-polarized light of the TFT-LCD display is 45 degrees, thus transforming the output emission into a circularly polarized light (5) with equal amplitudes of vibration in all azimuths, which is a good approximation of non-polarized light.;The advantage of the invention is its simplicity and minimal brightness loss. Moreover, it is highly suitable for production in industrial scale.
