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.

Abstract: The present disclosure provides a backlight source and a display device. A rigid element is arranged between a light strip of the backlight source and a light-entering surface of a light guide plate. One end of the rigid element is fixed onto the light strip, and the other end of the right element is fixed onto the light guide plate, so as to maintain a constant distance between the light strip and the light-entering surface of the light guide plate. An elastic element is arranged between the light strip and a back plate and at a side of the light strip opposite to the light-entering surface of the light guide plate. When the light guide plate is thermally deformed, a deformation force generated by the light guide plate is applied to the rigid element, so push the light strip to press against the elastic element.
