Claims9
A backlight module, comprising a light guide plate and a light collection component, wherein the light collection component comprises a light capturing device, the light capturing device comprises a connection opening, and the connection opening of the light capturing device is configured to introduce captured light into the light guide plate;
- wherein the light collection component further comprises a light conducting device, a light entrance of the light conducting device is connected to the connection opening, and a light exit of the light conducting device is connected to a light incident surface of the light guide plate;
- wherein an area of the light entrance of the light conducting device is greater than an area of the connection opening;
- wherein the light capturing device comprises a bottom reflection layer, a top transmission layer and an end reflection layer, a light exporting cavity is arranged between the top transmission layer and the bottom reflection layer, the connection opening is arranged at an end of the light exporting cavity, and the end reflection layer is arranged at an end of the light exporting cavity opposite to the connection opening;
- wherein the light capturing device further comprises a bottom transmission layer in contact with the light exporting cavity, the bottom reflection layer is oblique relative to the bottom transmission layer, wherein
- the bottom reflection layer comprises a first surface at a side of the bottom reflection layer adjacent to the bottom transmission layer, the first surface is a planar surface which is in connection with the end reflection layer and the bottom transmission layer and extends from the end reflection layer to the bottom transmission layer.
