Abstract

The invention discloses a polarization rotary switch, which includes a first transparent electrode and a second transparent electrode, and also includes a third transparent electrode, and a first twisted nematic liquid crystal is arranged between the first transparent electrode and the second transparent electrode ; The second twisted nematic liquid crystal is arranged between the second transparent electrode and the third transparent electrode; the incident light of the first twisted nematic liquid crystal and the second twisted nematic liquid crystal The orientations of the liquid crystals at the ends are the same or perpendicular to each other, and the first transparent electrode, the second transparent electrode and the third transparent electrode are all connected to a controllable power supply device. The polarization rotary switch provided by the present invention doubles the switching speed, solves the tailing problem in the liquid crystal display device well, doubles the shaking speed of the optical shaking device, and can be well applied in 2D / In the 3D switchable display device, due to the use of lower voltage for control, it is safer and has a longer service life.

Description

technical field [0001] The invention relates to the field of optics, in particular to a polarization rotary switch, an optical shaking device and a display device comprising the switch. Background technique [0002] The application of liquid crystals in the field of display is becoming more and more extensive and more and more important. As an elastic continuum, liquid crystals are stretchable, twistable and bendable. Liquid crystal display mainly utilizes the distorted characteristics of nematic liquid crystal molecules and the optical rotation of twisted liquid crystals. The polarization plane of incident light rotates along the twisted helical axis of liquid crystals. The rotation angle of liquid crystals determines the light transmission of liquid crystal cells, thus determining the brightness of the pixel. At present, liquid crystal cells mainly include twisted nematic (TN for short), super twisted nematic (STN for short), and double-layer super twisted nematic (DSTN)....
