  • Publication number: 20240126002
    Abstract: A backlight module includes a light source, a first prism sheet disposed on the light source, and a light type adjustment sheet disposed on a side of the first prism sheet away from the light source and including a base and multiple light type adjustment structures. The multiple light type adjustment structures are disposed on the first surface of the base. Each light type adjustment structure has a first structure surface and a second structure surface connected to each other. The first structure surface of each light type adjustment structure and the first surface of the base form a first base angle therebetween, and the second structure surface of each light type adjustment structure and the first surface of the base form a second base angle therebetween. The angle of the first base angle is different from the angle of the second base angle.
