Abstract:
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.

Abstract:
A flat panel display device comprising a backboard and a display panel fitted therewith is provided. The edge of the backboard is structured as a barrier wall extending perpendicular to the body of the backboard. A stepped groove is arranged on the interior face of the barrier wall for supporting the display panel and forming accommodating space between the display panel and the body of the backboard. The stepped groove extends from an outer end of the barrier wall towards the body of the backboard, and the depth of the stepped groove is consistent with the thickness of the display panel. The backboard is made of plastic plate containing a enhancing element. The flat panel display device according to the present disclosure can be designed as a light and thin display device with no frame, and thus is suitable for making an all-in-one machine.

A backlight module includes a bottom plate, and a fixing element which is fixed at one side of the bottom plate and used for fixing a quantum tube. The fixing element includes a bottom wall, and a first lateral wall, a second lateral wall, and a third lateral wall which extend upwards from a first end, a second end, and a third end of the bottom wall respectively. The first lateral wall and the second lateral wall are arranged facing each other. The quantum tube is fixed in an accommodating space that is formed by the bottom, the first lateral, the second lateral, and the third lateral walls. In the backlight module, since the quantum tube is fixed in a stable manner, a structural reliability of the backlight module can be ensured, and a high color gamut of the backlight module can be realized.
