Title:
LIQUID CRYSTAL LENS AND CONTROL METHOD THEREFOR, AND LIQUID CRYSTAL GLASSES
Document Type and Number:
WIPO Patent Application WO/2021/077409
Kind Code:
A1
Abstract:
A liquid crystal lens (100) having at least two drive regions. The liquid crystal lens (100) comprises a first electrode layer (1) and a second electrode layer (2). The first electrode layer (1) comprises a plurality of first electrode groups (10), each of the first electrode groups (10) comprising a plurality of first electrodes (101); the plurality of first electrodes (101) comprised in each of the first electrode groups (10) are configured to receive a plurality of first driving signals (SD1) on a one-to-one basis, and each of the at least two drive regions corresponds to at least one first electrode group (10). The second electrode layer (2) is provided opposite the first electrode layer (1), and comprises at least one second electrode (201) configured to receive at least one second driving signal (SD2) on a one-to-one basis. Driving voltages formed between the first driving signals (SD1) received by the first electrodes (101) located at the same position and the second driving signals (SD2) received by the corresponding second electrodes (201) are equal or substantially equal in the same drive region, and the absolute values of the driving voltages in different drive regions increase in the radial direction of the liquid crystal lens (100) and in a direction pointing to an edge from the center of the liquid crystal lens (100).
