    • A backlight module includes a light source, a light guide disposed on one side of the light source, a reflector disposed under the light guide, a lower diffuser disposed on the light guide, and a brightness enhancement film, which is disposed on the lower diffuser and includes a main part and several prism structures disposed side by side on a main part plane of the main part. Each prism structure includes first to third triangular prisms. The second triangular prism is adjacent to one side of the first triangular prism, and an adjacent angle adjacent to a base angle of the first triangular prism is a right angle. The third triangular prism is adjacent to another side of the first triangular prism, and an adjacent angle adjacent to another base angle of the first triangular prism is a right angle.
    • 背光模块包括光源,设置在光源一侧的光导,设置在光导下方的反射器,设置在光导上的下扩散器和设置在下扩散器上的亮度增强膜 并且包括在主要部分的主要部分平面上并排设置的主要部分和多个棱镜结构。 每个棱镜结构包括第一至第三三棱柱。 第二三棱镜与第一三角棱镜的一侧相邻,与第一三角棱镜的底角相邻的相邻角度是直角。 第三三角棱镜与第一三角棱镜的另一侧相邻,并且与第一三角棱镜的另一底角相邻的相邻角度是直角。
