An optical waveguide element and control method thereof, a backlight module and a display device. The optical waveguide element includes a cavity, a light incident surface and a light emergent surface, light entering the cavity from the light incident surface is configured to propagate and be totally reflected in the cavity; and a reflector array, located in the cavity and configured to be controllable to cause at least a part of the light incident on the reflector array to be reflected out of the light emergent surface or to continue being totally reflected at the light emergent surface.

Optical waveguide element and control method thereof, backlight module and display device

The present disclosure provides a backlight source adjustment method, a backlight source adjustment device and a display device. After acquiring intensity information and spectrum information of current ambient light, a color temperature corresponding to the current ambient light is determined in accordance with the spectrum information of the current ambient light, and a total current to be currently supplied to a backlight source is determined in accordance with the intensity information of the current ambient light. Brightness values of light source branches having different color ranges in the backlight source are determined in accordance with the determined color temperature corresponding to the current ambient light and the total current, and currents for the light source branches are adjusted, so as to adjust color gamut of the backlight source in accordance with the current ambient light.
