Circular polarization filter consisting of a wide spectrum chip of delay of one quarter of wave length (1) where the angle between the fast axis of the chip (2) and the vector of the electric field (4) of the linear polarized incident light of the monitor TFT-LCD is 45 degrees, thus converting the output to circular polarized light (5) with the same width of vibration to all azimuths, which constitutes a satisfactory approach of the non polarized light. The advantage of the invention is its simplicity, with minimum loss of illumination. In addition, it is suitable for production at industrial scale, as embedded element of TFT-LCD monitors. |
