[The analysis of polarized display characteristic of LCLV].

The polarized TN effect of LCLV is discussed, and the twist of LC molecule with the AC voltage in LCLV is analyzed after its reorientation. While changing the applied voltage continuously at certain frequency, the twist angle of LC molecule in TB3639 LCLV and the electro-optical characteristic of the LCLV were measured. The results show that when the voltage is changed in series, the transmittance of the incidence linearly polarized light will alter continuously and nonlinearly, and the twist degree may control the nonlinear change. And the 1800 twist of the LC molecule will make the curve of electro-optical characteristic of the LCLV steeper, which allows multicenter matrix addressing LCLV to have more matrix lines and higher contrast.
