Document Type and Number:
WIPO Patent Application WO/2019/214633
Kind Code:
A1
Abstract:
A diffuser, a backlight module, a liquid crystal display panel, and a display device. A diffuser (100) comprises a substrate layer (1), a white print layer (3), and a black print layer (2). The substrate layer (1) comprises an edge region (AA) and a light transmissive region (BB). The white print layer (3) and the black print layer (2) are located in the edge region (AA), and the black print layer (2) and the white print layer (3) are arranged in sequence along a direction from a light entrance surface (11) of the substrate layer (1) to a light exit surface (12) thereof. The orthographic projection of the black print layer (2) on the substrate layer (1) falls within the orthographic projection of the white print layer (3) on the substrate layer (1). In this way, the white print layer (3) can block a black shadow formed by the reflection of the black print layer (2) on a prism sheet (6), thereby improving the quality of a displayed scene.
