Abstract

The invention relates to the field of display technology, and discloses an optical device, a display device and a driving method thereof. The optical device includes two substrates of the cell, and electrodes are arranged on the two substrates, and a voltage is applied to the electrodes of each substrate to form a transverse electric field to drive the liquid crystal molecules close to the substrate to deflect, so that the liquid crystal molecules close to each All the liquid crystals on the substrate can form a liquid crystal lens, so that a double-layer liquid crystal lens structure can be formed by using one liquid crystal cell. Since the alignment accuracy of the two substrates of a liquid crystal cell is relatively high, it can ensure that the electrodes on the two substrates are consistent in spatial frequency and overcome the moiré problem.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an optical device, a display device and a driving method thereof. Background technique [0002] Among the applications of intelligent display functions, anti-peep display is an application with relatively high demand. However, the current anti-peeping mode is fixed and cannot be switched to the sharing mode. Since the adjustment of the liquid crystal lens to the light can be controlled by electrodes, the use of liquid crystal lenses can realize the automatic switching between anti-peeping and sharing, and the double-layer liquid crystal lens can achieve a larger sharing angle than the single-layer liquid crystal lens. [0003] In the prior art, the main structure of the liquid crystal lens is two substrates of the box, the liquid crystal filled between the two substrates, and a plurality of strip electrodes arranged on one of the substrates and a plate arranged on the other sub...
