Therefore, when the plurality of blades 1321 in the light adjusting portion 132 are deflected relative to the supporting frame 131, the blades 1321 are biased in a direction forming a set angle with the backlight assembly 12, so that the included angle between each of the blades 1321 in the adjustable grating assembly 13 and the backlight assembly 12 can be effectively adjusted according to different usage scenarios, and the angle of the backlight emitted by the backlight assembly 12 incident on the display panel 11 can be adjusted, so as to optimize the viewing angle of the viewer, and thus the viewer can obtain a better viewing experience.

In other embodiments, the angles between the plurality of blades 1321 in each of the two dimming parts 132 and the backlight assembly 12 after the deflection adjustment are the same, and are specifically determined by the viewing angle of the viewer, for example, when the viewer is on the left side of the display panel 11, the plurality of blades 1321 in all the dimming parts 132 can deflect to the left, and when the viewer is directly in front of the display panel 11, the plurality of blades 1321 in the dimming parts 132 on the left and right sides of the adjustable grating assembly 13 can deflect to the right and left, respectively, and the plurality of blades 1321 in the dimming part 132 in the middle can be offset vertically to the display panel 11, so that the viewer obtains a better viewing angle.
