Abstract
A backlight module includes at least one light source, a lamp cover and a circuit board. The lamp cover has a containing portion and at least one projection. The containing portion is arranged for containing the light source. The projection is located at an outer side of the containing portion on which the circuit board is placed so that at least one fixing portion of the circuit board is in contact with the projection for constraining movements of the circuit board relative to the lamp cover.
Claims20
A display device, comprising:
- a display panel;
- a circuit board electrically connected to the display panel and having at least one fixing portion;
- and
- a backlight module disposed at one side of the display panel, wherein the backlight module comprises:
- at least one light source;
- a lamp cover having an inner surface and an outer surface, wherein the at least one light source is surrounded by the inner surface;
- and
- at least one protruding portion located at the outer surface;
- and wherein
- the circuit board is disposed on the outer surface of the lamp cover;
- and
- the at least one protruding portion is in contact with the at least one fixing portion for constraining movements of the circuit board relative to the lamp cover.
A method of fixing a circuit board on a backlight module, the method comprising:
- providing a lamp cover having at least one protruding portion and a containing portion, wherein the containing portion is arranged for containing, at an inner side thereof, at least one light source of the backlight module, and the at least one protruding portion is located at an outer side of the containing portion;
- providing at least one fixing portion on the circuit board;
- and
- placing the circuit board on the outer side of the containing portion so that the at least one fixing portion is in contact with the at least one the protruding portion to constrain movements of the circuit board relative to the lamp cover.
A backlight module for a display device, said backlight module comprising:
- at least one light source;
- a lamp cover having an inner surface and an outer surface, wherein the at least one light source is surrounded by the inner surface;
- at least one protruding portion located at the outer surface;
- and
- a circuit board disposed on the outer surface of the lamp cover and having at least one fixing portion in contact with the at least one protruding portion which constrains movements of the circuit board relative to the lamp cover.
