所述导光板12设于所述背板11围成的腔体中，具体的，所述导光板12平行地设于所述底板111上方。其中所述导光板12具有一入光面121和一出光面122，所述导光板12背离所述出光面122的一面朝向所述背板11的底板111，其入光面121朝向所述侧板112。
为了增加所述导光板12的表面的透明度，提高所述导光板12的透光率，需要对所述导光板12的表面进行抛光处理，使所述导光板12的表面形成抛光面。本实施例中，所述导光板12的透光率为70％-95％。
所述光学膜片13a设于所述导光板12的出光面122上，所述光学膜片13a上具有一透明区131a，所述通孔110对应所述透明区131a。
所述光学膜片13a具有一开孔130，该开孔130中设有透明薄膜14，所述透明薄膜14所在的区域即为透明区131a。为了不影响光学效果，本实施例中，所述透明薄膜14所用的材料与其所对应的光学膜片13a所用材料一致，只是在制作工艺过程中，需要对设于所述开孔130中的薄膜进行透明化处理，如降低薄膜的雾化程度，即可形成所述透明薄膜14。其中所述透明区131a的透光率为70％-95％，即所述透明薄膜14的透光率为70％-95％。
本实施例中，所述通孔110的形状、尺寸与所述开孔130的形状、尺寸一致，所述通孔110的中轴线与所述开孔130的中轴线重合。这种设计，能够避免因开孔130过大影响光学膜片13a的作用，或者开孔130过小，影响透光效果以及摄像装置的光线采集效果。
本实施例中，所述光学膜片13a包括扩散膜片、棱镜片等其中至少一种结构。例如，在实际制备过程中，若同时采用扩散膜片、棱镜片的叠层结构，则需要同时在扩散膜片和棱镜片的对应所述通孔110区域设置开孔130，并在对应的开孔130中设置透明薄膜14。其中，在所述扩散膜片中，所述透明薄膜14的所用材料与所述扩散膜片的所用材料一致；在所述棱镜片中，所述透明薄膜14的所用材料与所述棱镜片的所用材料一致。
所述光源16为LED光源或者OLED光源，LED光源或者OLED光源分布在所述侧板112上，且朝向所述导光板12的入光面121。
所述反射片15贴覆于所述导光板12朝向所述背板11的一面。具体的，所述反射片15贴覆于所述导光板12非对应所述通孔110的区域，这样可以避免所述通孔110处的光线被反射片15遮挡，以影响摄像效果。
本实施例中，所述反射片15是由若干个微反射片组成，分别相互平行设置，相邻的所述微反射片之间留有间隙。
如图2所示，实施例1还提供了一种显示装置100，包括所述的背光模组1以及显示面板2，所述光学膜片13a朝向所述显示面板2。本实施例中，主要设计要点在于所述背光模组1，至于显示装置100的其他结构，如摄像装置等就不再一一赘述。

所述导光板12设于所述背板11围成的腔体中，具体的，所述导光板12平行地设于所述底板111上方。其中所述导光板12具有一入光面121和一出光面122，所述导光板12背离所述出光面122的一面朝向所述背板11的底板111，其入光面121朝向所述侧板112。
为了增加所述导光板12的表面的透明度，提高所述导光板12的透光率，需要对所述导光板12的表面进行抛光处理，使所述导光板12的表面形成抛光面。本实施例中，所述导光板12的透光率为70％-95％。
所述光学膜片13b设于所述导光板12的出光面122上，所述光学膜片13b上具有一透明区131b，所述通孔110位于所述透明区131b的下方。
本实施例中，整个光学膜片13b均设置成透明区131b，即在制作工艺过程中，需要对设于所述光学膜片13b进行透明化处理，如降低薄膜的雾化程度，即可形成整个透明的光学膜片13b。其中所述透明区的透光率为70％-95％，即所述整个透明的光学膜片13b的透光率为70％-95％。
本实施例中，所述光学膜片13b包括扩散膜片、棱镜片等其中至少一种结构。例如，在实际制备过程中，若同时采用扩散膜片、棱镜片的叠层结构，则需要同时对扩散膜片和棱镜片进行透明化处理，使扩散膜片、棱镜片的透光率为70％-95％。
