一种背光模组（210），包括背板（211），包括被动层（2111）及设置在所述被动层（2111）之下的主动层（2112），其中，所述主动层（2112）的热膨胀系数大于所述被动层（2111）的热膨胀系数；加热装置（212），通过控制对所述背板（211）的加热温度，以调节背板（211）朝向液晶显示面板（220）弯曲的曲率。背光模组（210），包括上述背板（211）的液晶显示装置和包括上述背板（211）的发光二极管显示装置，均可实现弯曲曲率任意调节。 A backlight module (210), comprising a back plate (211) and a heating device (212); the back plate (211) comprises a passive layer (2111) and an active layer (2112) disposed below the passive layer (2111); the thermal expansion coefficient of the active layer (2112) is greater than the thermal expansion coefficientthat of the passive layer (2111); the heating device (212) controls the heating temperature of the back plate (211) to adjust the bending curvature of the back plate (211) toward a liquid crystal display panel (220). The bending curvature of each of the backlight module (210), a liquid crystal display device comprising the back plate (211) and a light-emitting diode display device comprising the back plate (211) can all be freely adjusted.
