Title:
LIQUID CRYSTAL GLASSES AND LIQUID CRYSTAL DISPLAY PANEL HAVING LIGHT LEAKAGE ELIMINATION ELEMENTS
Document Type and Number:
WIPO Patent Application WO/2020/233494
Kind Code:
A1
Abstract:
Liquid crystal glasses and a liquid crystal display panel having light leakage elimination elements (4). The liquid crystal glasses comprise: a first substrate (5) and a second substrate (6) which are cell-assembled; a first electrode (8) provided on the side of the first substrate (5) facing the second substrate (6); a second electrode (9) provided on the side of the second substrate (6) facing the first substrate (5) and located on the side of the first electrode (8) away from the first substrate (5); a liquid crystal layer filled between the first electrode (8) and the second electrode (9); a lens unit (1) comprising a valid area (2) and an invalid area (3), one of the valid area (2) and the invalid area (3) being constructed to converge collimated light beams by means of refraction, and the other of the valid area (2) and the invalid area (3) being constructed to diverge parallel light beams by means of refraction; light leakage elimination elements (4) provided between the second electrode (9) and the lens unit (1), the orthographic projections of the light leakage elimination elements (4) on the second substrate (6) at least partially overlapping the orthographic projection of the invalid area (3) on the second substrate (6), each light leakage elimination element (4) comprising a wire grid polarizer (41) and a half wave plate (42) sequentially stacked away from the second electrode (9); and a light blocking element (10) provided on the side of the liquid crystal layer away from the second electrode (9) and constructed to block light passing through the light leakage elimination elements (4) and the invalid area (3) from being emitted outside the liquid crystal glasses.
