Abstract
The present disclosure relates to a backlight module and a display device. The backlight module includes: a back plate; a reflective sheet and a plurality of light sources sequentially disposed at one side of the back plate; and an optical film disposed at one side of the reflective sheet facing away from the back plate and at a given distance between the reflective sheet, characterized in that it further includes: at least one transflective film disposed at one side of the optical film facing the light source.
Claims8
A backlight module, comprising:
- a back plate;
- a reflective sheet and a plurality of light sources sequentially disposed at one side of the back plate;
- and
- an optical film disposed at one side of the reflective sheet facing away from the back plate and at a given distance from the reflective sheet,
- wherein the backlight module further comprises at least one transflective film disposed at one side of the optical film facing the light sources;
- and
- wherein the number of the transflective films is the same as the number of light sources, and the transflective films are arranged in a one-to-one correspondence with the light sources;
- and
- wherein each transflective film is in a shape of central symmetry, and an orthographic projection of a centroid of the transflective film on the back plate coincides with a light emission center of a corresponding light source;
- and
- wherein the transflective film is in a shape of circular or regular polygon, and
- wherein a maximum width of each transflective film and a maximum width of a corresponding light source satisfy a relation:
- 2H<L<6H;
- where H is the maximum width of the light source and L is the maximum width of the transflective film, and
- wherein the transflective film is supported by a supporting member and the supporting member comprises a substantially cylindrical support disposed between the reflective sheet and the transflective film.
