Abstract

We demonstrate a reflective polarizer-free electro-optical switch using dye-doped polymer-stabilized blue phase liquid crystals (DDPSBP-LC). At the voltage-off state, the dye molecules and liquid crystals form the structure of the double twist cylinders. As a result, the DDPSBP-LC is in dark state due to the combination of Bragg reflection and light absorption. At the voltage-on state, the blue phase structure is unwound locally. The DDPSBP-LC is then in bright state because of the small light absorption only. The applications of such a switch are shutter glass of 3D displays, and electronic papers.

Fig. 3

(a)The voltage-dependent reflectance of DDPSBP-LC under an unpolarized light (black solid line), 0 degree linearly polarized light (blue diamonds), 30 degree linearly polarized light (red squares), and 90 degree linearly polarized light (pink triangles). The DDPSBP-LC shows the hysteresis when the voltage is ramped up black solid line and down (gray solid line). (b) Displayed image of the reflective polarizer-free electro-optical switch using DDPSBPLC. Dye concentration: 2.5%. The voltage was 100 Vrms at the white regions and 0 Vrms at the dark regions. A white paper was placed behind the bottom substrate to act as a diffusive reflector. T = 24 °C.
