Embodiment 1
[0066] Example 1: Dual-frequency bistable liquid crystal composition and dielectric constant performance.
[0067] The dual-frequency bistable liquid crystal display of the present invention is made of the dual-frequency nematic phase liquid crystal in which HEF951700-100 is used.
[0068] The dual-frequency liquid crystal has the dielectric constant performance shown in Table 1 below at room temperature of 25°C:
[0069]
[0070] As can be seen from the contents of Table 1, the negative value conversion frequency value of this embodiment is 50KHz, when higher than the negative value conversion frequency value, the voltage dielectric constant anisotropy parameter value difference of the liquid crystal is a state of a negative value, and The positive value conversion frequency value is 100Hz, that is, when the positive value conversion frequency value is lower than the positive value conversion frequency value, such as a voltage frequency of 50Hz, the voltage dielectric cons...
Embodiment 2
[0072] Embodiment 2: Dual-frequency bistable liquid crystal display.
[0073] Such as image 3 As shown, the dual-frequency bistable liquid crystal composition prepared in Example 1 is poured into a liquid crystal cell 10 with a spacing D of 4 μm, and the inner surfaces 111, 121 of the two substrates 11, 12 of the liquid crystal cell 10 are each coated with one layer The alignment layers 15 and 16 are arranged in parallel, and the alignment layer 15 / 16 of one of the substrates 11 / 12 is subjected to an alignment rubbing process. In this embodiment, the color film layer 17 of the liquid crystal cell 10 is a black light-absorbing film, whereby when applying a 50Hz frequency low-frequency voltage, the pixels of the liquid crystal cell 10 appear black, and when applying a 50KHz frequency high-frequency voltage , the pixels of the liquid crystal cell 10 display green.
[0074] In addition, the dual-frequency bistable liquid crystal composition of the present invention can be imple...
