  • Publication number: 20210404628
    Abstract: The present disclosure provides a light homogenizing film, a backlight module and a display device. The light homogenizing film includes a substrate film layer on which a plurality of light homogenizing structures are arranged in an array. The light homogenizing structure includes: a first recess in a regular pyramid shape positioned on a light incident surface of the substrate film layer, and a second recess in a regular pyramid shape positioned on a light emitting surface of the substrate film layer. On a plane where a main body of the substrate film layer is located, an orthographic projection of the second recess completely covers an orthographic projection of the first recess, and the orthographic projections of the first and second recesses are regular polygons which have overlapped centers, the same number of sides and the same orientation.

  • Publication number: 20210191029
    Abstract: A backlight module includes: a light guide plate, and a prism film located on a side of a light exit surface of the light guide plate including a substrate and a plurality of strip-shaped prisms disposed on a side of the substrate facing the light guide plate, extending in a first direction and arranged in a second direction; and the base angles of each strip-shaped satisfy conditions that two light rays exiting from the light guide plate that have symmetrical angles with a normal line of the light exit surface of the light guide plate are respectively incident on two sides of the strip-shaped prism, and then exit in a same set light exit direction the prism film has at least two light exit directions. The two light rays are respectively emitted by the side-type backlight and reflected by the reflective sheet, or are respectively emitted by the double light bars.
