Document Type and Number:
WIPO Patent Application WO/2020/082526
Kind Code:
A1
Abstract:
A lightguide plate (300), a backlight module (100), and a display device (1000). The lightguide plate (300) mainly comprises a body (310), a plurality of first strip-shaped structures (320) and a plurality of second strip-shaped structures (330). The body (310) is provided with an optical surface (311), a light incident surface (312), and an opposite light incident surface (313). The light incident surface (312) and the opposite light incident surface (313) respectively are connected to either opposite side of the optical surface (311). The body (310) is provided with a bored hole (311a) running through the optical surface (311). The optical surface (311) is divided into a first area (A1) and a second area (A2) by an imaginary line (M1), and, the imaginary line (M1) is perpendicular to the bored hole (311a), the first area (A1) is closer to the light incident surface (312), and the second area (A2) is closer to the opposite light incident surface (313). At least a part of each first strip-shaped structure (320) is provided in the first area (A1). The second strip-shaped structures (330) are provided in the second area (A2). The direction of arrangement or density of the first strip-shaped structures (320) is different from the direction of arrangement or density of the second strip-shaped structures (330).
