Abstract: The embodiments of the present disclosure provide a backlight module and a display device, which increase the brightness range of the lateral entrance backlight module, thereby improving the HDR display effect of the display device. The backlight module in the embodiment of the present disclosure includes at least two lateral entrance light guide plates, each lateral entrance light guide plate is provided with a light bar. The number of light bars of the backlight module is increased, thereby increasing the maximum brightness of the backlight module. The overall brightness variation range of the backlight module is thus increased. In addition, the light bar of each lateral entrance light guide plate can be separately controlled, thereby increasing the brightness range of the backlight module. Therefore, the backlight module provided by this solution can effectively improve the HDR display effect of the display device.
