Title:
DIMMING ASSEMBLY, BACKLIGHT MODULE, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/208638
Kind Code:
A1
Abstract:
A dimming assembly (100), comprising a first prism (1) and a second prism (2). The first prism (1) has a first surface (M1) and a second surface (M2) which are opposite to each other; the first surface (M1) comprises a plurality of first dimming parts (11), each first dimming part (11) comprises two first side surfaces (111), and the ends of the two first side surfaces (111) distant from the second surface (M2) intersect at a first intersection line (112). The second prism (2) is arranged on the side of the second surface (M2) of the first prism (1), the surface of the second prism (2) close to the second surface (M2) comprises a plurality of second dimming parts (21), each second dimming part (21) comprises two second side surfaces (211), and the ends of the two second side surfaces (211) close to the second surface (M2) intersect at a second intersection line (212). The spacing (L1) between the orthographic projections of every two adjacent first intersection lines (112) on the second surface (M2) is smaller than the spacing (L2) between the orthographic projections of every two adjacent second intersection lines (212) on the second surface (M2).
