    Abstract: A backlight module, a control method and control device thereof, and a corresponding display device are disclosed. With this backlight module, switching between a narrow view angle and a wide view angle is achieved without the additional need for carrying any auxiliary tools. A light exit region of the backlight module includes a first light exit region and a second light exit region located on a periphery of the first light exit region. The backlight module includes a first light source component and a second light source component. Light emitted from the first light source component is emitted out through the first light exit region, and light emitted from the second light source component is at least partially emitted out through the second light exit region. Switch control ends for the first light source component and the second light source component are not electrically connected.
