SPECTACLES WITH DELAY PIECES OF ONE QUARTER OF WAVE LENGTH FOR WORK ON MONITORS WITH LINEAR OUTPUT POLARIZATION.

摘要

Spectacles (8) that incorporate wide spectrum delay pieces of one quarter of wave length (1), where the angle between the prompt axis (2) of the pieces (1) and the vector of the electric field (4) of the linear polarized incident light of the TFT-LCD monitor is 45 degrees, thus converting the output to circular polarized light (5) with the same range 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.Furthermore, it is suitable for production at industrial scale.
