Backlight module
View Patent ↗A backlight module includes a light guide plate having a light incident surface, a light source module, at least one catch member, and a cushion member. The light source module is disposed adjacent to the light incident surface and has at least one light-emitting element, wherein a light beam emitted by the light-emitting element is capable of entering the light guide plate through the light incident surface. The catch member engages with one end of the light source module, wherein the catch member has at least one extension part extending towards the light incident surface of the light guide plate, and the extension part has an end surface facing the light incident surface. The cushion member is disposed between the light guide plate and the light source module and is adjacent to the light incident surface of the light guide plate and the end surface of the catch member.
1. A backlight module, comprising:
a light guide plate having a light incident surface;
a light source module disposed adjacent to the light incident surface and having at least one light-emitting element, wherein a light beam emitted by the light-emitting element is capable of entering the light guide plate through the light incident surface;
at least one catch member engaging with one end of the light source module, wherein the catch member has at least one extension part extending towards the light incident surface of the light guide plate, and the extension part has an end surface being disposed beside and facing the light incident surface; and
a cushion member disposed between the light incident surface of the light guide plate and the light source module, wherein the cushion member touches the end surface of the extension part of the catch member and is between the end surface of the extension part of the catch member and the light incident surface of the light guide plate, so that the end surface of the extension part of the catch member is capable of being against the light incident surface of the light guide plate through the cushion member.
2. The backlight module as claimed in claim 1 , further comprising:
at least one fastening member capable of securing the light source module and the catch member to a back plate.
3. The backlight module as claimed in claim 2 , wherein the fastening member is a screw.
4. The backlight module as claimed in claim 1 , wherein the light source module is a light emitting diode light bar.
5. The backlight module as claimed in claim 1 , wherein the cushion member comprises an elastic material.
6. A backlight module, comprising:
a light guide plate having a light incident surface;
a light source module disposed adjacent to the light incident surface and having at least one light-emitting element, wherein a light beam emitted by the light-emitting element is capable of entering the light guide plate through the light incident surface;
a first catch member engaging with a first end of the light source module, wherein the first catch member has an extension part extending towards the light incident surface of the light guide plate, and the extension part of the first catch member has an end surface being disposed beside and facing the light incident surface;
a second catch member pressing against a second end of the light source module, wherein the second catch member has an extension part extending towards the light incident surface of the light guide plate, and the extension part of the second catch member has an end surface being disposed beside and facing the light incident surface;
a cushion member disposed between the light incident surface of the light guide plate and the light source module and touching the end surface of the extension part of the first catch member and the end surface of the extension part of the second catch member, wherein the cushion member is between the end surface of the extension part of the first catch member and the light incident surface and between the end surface of the extension part of the second catch member and the light incident surface, so that the end surface of the extension part of the first catch member and the end surface of the extension part of the second catch member are capable of being against the light incident surface of the light guide plate through the cushion member; and
at least one fastening member capable of fastening the first catch member, the second catch member, and the light source module together.
7. The backlight module as claimed in claim 6 , wherein the second catch member engages with the second end of the light source module.
8. The backlight module as claimed in claim 6 , wherein the fastening member is a screw, and the screw secures the first catch member, the second catch member, and the light source module to a back plate.
9. The backlight module as claimed in claim 6 , wherein the light source module is a light emitting diode light bar.
10. The backlight module as claimed in claim 6 , wherein the cushion member comprises an elastic material.
