Abstract
A backlight module including a back board, a reflector, at least one light source, at least one lens unit, and a light leakage feature is disclosed. The reflector includes a base and at least one side wall connected to the base and is disposed on the back board. The light source is disposed on the board and emits light. The lens unit is disposed on the light source and configured to diffuse the light emitted from the light source for generating light rays impinging on the side wall. The light-leakage feature is disposed at the side wall and configured to allow some of the light rays to pass through the side wall.
Claims16
A backlight module comprising:
- a back board;
- a reflector disposed on the back board, the reflector comprising a base and a side wall connected to the base;
- at least one light source disposed on the back board, protruding through the base and neighboring to the side wall;
- at least one lens unit disposed on the light source and configured to output light rays by diffusing light emitted from the light source, wherein some of the light rays impinge on at least a portion of the side wall;
- and
- a light-leakage feature disposed at the side wall and configured to allow some of the light rays to pass through the side wall, wherein the light-leakage feature comprises a plurality of holes penetrating through the side wall, and whole outline of each of the holes is separated from at least one edge of the side wall.
A backlight module comprising:
- a back board;
- a reflector disposed on the back board and comprising a base and a side wall connected to the base, wherein a surface of the reflector facing the back board is covered with the back board, and the side wall is in contact with the back board;
- at least one light source disposed on the back board, protruding through the base and neighboring to the side wall;
- at least one lens unit disposed on the light source and configured to output light rays by diffusing light emitted from the light source, wherein some of the light rays impinge on at least a portion of the side wall;
- and
- a plurality of holes penetrating through the side wall to expose the back board.
A backlight module comprising:
- a back board;
- a reflector disposed on the back board and comprising a base and a side wall connected to the base, wherein the base is enclosed by the side wall to form a cavity;
- at least one light source disposed on the back board, protruding through the base and neighboring to the side wall;
- at least one lens unit disposed on the light source and configured to output light rays by diffusing light emitted from the light source, wherein some of the light rays impinge on at least a portion of the side wall;
- a diffuser plate disposed over the back board and having a surface facing the cavity, wherein the surface of the diffuser plate is a plane without a hole;
- and
- a light-leakage feature disposed at the side wall and configured to allow some of the light rays to pass through the side wall.
