The invention provides a backlight module which comprises a first light-emitting part, a second light-emitting part, a first light-emitting diode matrix and a second light-emitting diode matrix. The second light-emitting part comprises a light-emitting panel and a light modulation plate, the light-emitting panel is used for emitting second backlight in the direction of the first light-emitting part, and the light modulation plate is used for reducing the diffusion angle of the second backlight in the first direction; the control module is used for controlling the light emitting state of the first light emitting part and the light emitting state of the second light emitting part, so that the backlight module is switched between a first state and a second state; wherein in the first state, the first light-emitting part emits the first backlight, and the second light-emitting part does not emit light; and in the second state, the first light-emitting part does not emit light, the second light-emitting part emits the second backlight, and the second backlight penetrates through the first light-emitting part. The invention further provides a display module applying the backlight module and a vehicle.
本申请提供一种背光模组,包括:第一发光部,所述第一发光二极管矩阵用于出射第一背光;第二发光部,包括发光面板以及光调制板,所述发光面板用于向所述第一发光部的方向出射第二背光,所述光调制板用于减小所述第二背光在第一方向上的扩散角;以及控制模块,所述控制模块用于控制所述第一发光部和所述第二发光部的发光状态,以使所述背光模组在第一状态和第二状态之间切换;其中,在所述第一状态下,第一发光部发出所述第一背光,第二发光部不发光;在所述第二状态下,所述第一发光部不发光,所述第二发光部发出所述第二背光,所述第二背光穿过所述第一发光部。本申请还提供一种应用上述背光模组的显示模组以及车辆。
