Title:
TUNABLE BAND STOP FILTER AND DRIVE METHOD THEREFOR, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/233127
Kind Code:
A1
Abstract:
Disclosed are a tunable band stop filter, a drive method for a tunable band stop filter, and an electronic apparatus. The tunable band stop filter comprises a first substrate (110), a second substrate (120), and a liquid crystal layer (130) sandwiched between the first substrate (110) and the second substrate (120). The first substrate (110) comprises a wire structure (1120) on a first base substrate (111). The second substrate (120) comprises a common electrode (122) on a second base substrate (121). The wire structure (1120) comprises a first wire structure (113) and a second wire structure (114), wherein the first wire structure (113), the common electrode (122), and the liquid crystal layer (130) between the first wire structure (113) and the common electrode (122) constitute a first phase modulation structure (140); and the second wire structure (114), the common electrode (122), and the liquid crystal layer (130) between the second wire structure (114) and the common electrode (122) constitute a second phase modulation structure (150).
