The invention discloses a backlight module for a liquid crystal display screen and the liquid crystal display screen. The backlight module comprises a display screen shell and a backlight module shell, wherein the display screen shell and the backlight module shell are both arranged in a supporting inner shell, two side moving shells slidably penetrate through the two sides of the supporting inner shell, two supporting plates are installed on the supporting inner shell, two buffering assemblies are rotatably installed on the supporting plates, the ends, away from the supporting plates, of the buffering assemblies are rotatably connected with second adjusting blocks, and the two second adjusting blocks are rotatably installed at the two ends of a second lead screw. According to the backlight module for the liquid crystal display screen and the liquid crystal display screen, through the design that the distance between two cleaning rollers can be adjusted, the two sides of the display screen can be cleaned at the same time, and efficient cleaning of the display screen is guaranteed; and through the arrangement of cleaning brushes capable of entering or exiting from the cleaning rollers, the cleaning brushes can be retracted into the cleaning rollers when cleaning is not needed, the cleaning brushes are prevented from influencing a user who watches the display screen, and meanwhile the cleaning brushes are not influenced when retracted into the two side moving shells.

    本发明公开一种用于液晶显示屏的背光模组以及液晶显示屏,包括显示屏壳体、背光模组壳体,显示屏壳体、背光模组壳体均设置于支撑内壳内,支撑内壳两侧滑动贯穿有两个侧移壳,支撑内壳上安装有两个支撑板,支撑板上转动安装有两个缓冲组件,缓冲组件远离支撑板一端转动连接第二调节块,两个第二调节块转动安装于第二丝杠两端。本发明通过两个清扫辊可以调节间距的设计,该用于液晶显示屏的背光模组以及液晶显示屏可以同时对显示屏两侧进行清扫,保证对显示屏的高效率清扫,通过设置可以进出清扫辊的清扫刷,在不需要清扫的时候可以将清扫刷收回至清扫辊内,在防止清扫刷对用户观看显示屏造成影响,同时不影响清扫刷收回至两个侧移壳内。
