LIQUID CRYSTAL DISPLAY DEVICE AND CURVED BACKLIGHT ASSEMBLY THEREOF |
摘要 |
A curved backlight assembly includes a light source, a curved light guide plate (LGP), a heat-dissipating plate, a supporting plate and a connecting member. The light source is abutted with the curved LGP. The heat-dissipating plate and supporting plate are connected by the connecting member to thereby form a curved backplane. The curved LGP is arranged on the curved backplane. Connected ends of the heat-dissipating plate and supporting plate are formed with elongated slots. The connecting member penetrates through elongated slots to connect the heat-dissipating plate and the supporting plate. A dimension of the curved backplane is increased or decreased with a relative displacement between the heat-dissipating plate and supporting plate to match with expansion or contraction of the curved LGP. The present invention has a simple structure. An optical coupling distance between the light source and curved LGP is shortened and the light incidence efficiency is improved. |

1. A curved backlight assembly comprising: a light source, a curved light guide plate, a heat-dissipating plate with a preset curvature radius, a supporting plate with a preset curvature radius, and a connecting member; wherein
the light source is abutted with the curved light guide plate; the heat-dissipating plate and the supporting plate are connected by the connecting member to thereby form a curved backplane, and the curved light guide plate is arranged on the curved backplane; connected ends of the heat-dissipating plate and the supporting plate respectively are formed with elongated slots, the connecting member penetrates through the elongated slots to connect the heat-dissipating plate and the supporting plate together, a dimension of the curved backplane is increased or decreased with a relative displacement between the heat-dissipating plate and the supporting plate to match with expansion or contraction of the curved light guide plate. |
