Abstract: The invention provides a backlight module and an LCD device. The backlight module includes a backplane, a middle frame, a light source, and an LGP optically coupled with the light source; the backplane, the middle frame and the LGP form a long and narrow cavity on the light incident side inside the backlight module, and the light source is arranged in the cavity; the long and narrow cavity wall of the cavity is provided with air vents which enable convection to be formed between the air inside the cavity and the air outside the cavity. In the invention, because the cavity wall of the cavity formed by the backplane, the middle frame and the LGP inside the backlight module around the lightbar is provided with air vents extending to the outside of the backlight module, convection is formed between the air with higher temperature inside the cavity and the air with lower temperature outside the cavity by the air vents. Thus, heat exchange is conducted between the heat in the cavity of the backlight module and the outside air in time, and the temperature in the cavity of the backlight module and the temperature of the cavity wall are reduced.

Abstract: The invention provides a backlight module and an LCD device including the backlight module. The backlight module includes an LGP, a lightbar optically coupled with the LGP, and an outer frame. The lightbar is arranged on the outer frame from the inner side of the backlight module. In the invention, because the lightbar is arranged on the outer frame of the backlight module, the lightbar can directly exchange heat with the outside air via the outer frame to dissipate heat; because the lightbar is directly arranged on the outer frame, the heat conduction path is shortened to a great extent. Thus, the heat emitted by the lightbar can be dissipated via the outer frame in time; the inside temperature of the backlight module is reduced, the stability and the service life of the components in the backlight module are increased, and the phenomenon that the stability of the LCD panel is affected by overhigh temperature is avoided.

Abstract: The invention provides a backlight module and an LCD device. The backlight module includes an LGP, point light source(s), and a backplane. The side wall of the backplane is provided with a pit extending to the outside of the backlight module relative to the light incident surface of the LGP, and the light sources are arranged on the pit. In the invention, because the position of the backlight module where the light sources are fixed is provided with the pit, the distance between the light source and the inner edge of the rubber frame is added due to pit, i.e. the A value is increased. Thus, the dark zones between every two LEDs of the light source can be effectively eliminated, and hotspot can be prevented from occurring in the active area of the LCD device. Meanwhile, after the A value is increased, corresponding A value can be selected to enable the frame of the LCD device to be narrowed, namely the A value is between the critical value that the hotspot cannot occur and the maximum A value obtained by the pit; thus, the frame of the LCD device becomes narrower, and the active area of the LCD device is increased.

Abstract translation: 本发明提供背光模块和LCD装置。 背光模块包括LGP，点光源和背板。 背板的侧壁设置有相对于LGP的光入射面延伸到背光模块的外部的凹坑，并且光源布置在凹坑上。 在本发明中，由于固定有光源的背光模块的位置设置有凹坑，所以由于凹坑而增加了光源与橡胶框的内缘之间的距离，即A值增大。 因此，可以有效地消除光源的每两个LED之间的暗区，并且可以防止在LCD装置的有效区域中发生热点。 同时，在增加A值之后，可以选择相应的A值来使LCD装置的帧变窄，即A值在不能发生热点的临界值和由坑获得的最大A值之间 ; 因此，LCD装置的框架变窄，并且LCD装置的有效面积增加。
