Abstract
A backlight assembly includes a light source part, a light guide plate, a container, and a support member. The light source part has a light emitting surface to emit light, and the light guide plate has a light incident surface to guide light. The container includes a bottom portion and sidewalls to receive the light source part and the light guide plate. The support member pushes the light guide plate toward the bottom portion to more closely maintain the position of the light incident surface with respect to the light emitting surface. This helps to prevent misalignment between the light exist surface and the light incident surface, maintaining the quantity of light supplied to the light guide plate.
Claims18
A backlight assembly comprising:
- a light source part having a light emitting surface;
- a light guide plate having at least one light incident surface so as to receive light from the light source part;
- a container including a bottom portion and sidewalls to receive the light source part and the light guide plate;
- and
- a support member extending from an upper portion of the light source part toward the light guide plate to apply pressure to an edge portion of the light guide plate to maintain a position of the light guide plate within the container,
- wherein the support member comprises:
- a support portion supporting the light guide plate by pressing the edge portion of the light guiding plate toward the bottom portion, the support portion extending substantially parallel to the light guide plate,
- an inclined portion extending obliquely from the supporting portion, and
- a coupling portion extending substantially parallel to the support portion from the inclined portion.
A display apparatus comprising:
- a display panel positioned to receive a light so as to display an image;
- and
- a backlight assembly configured to supply the light to the display panel,
- wherein the backlight assembly comprises:
- a light source part having a light emitting surface;
- a light guide plate having at least one light incident surface so as to receive the light from the light source part;
- a container including a bottom portion and sidewalls to receive the light source part and the light guide plate;
- and
- a support member extending from an upper portion of the light source part toward the light guide plate to apply pressure to an edge portion of the light guide plate to maintain a position of the light guide plate within the container,
- wherein the support member comprises:
- a support portion supporting the light guide plate by pressing the edge portion of the light guiding plate toward the bottom portion, the support portion extending substantially parallel to the light guide plate,
- an inclined portion extending obliquely from the supporting portion, and
- a coupling portion extending substantially parallel to the support portion from the inclined portion.
