For example, the driving unit 11 drives the adjusting member 10 to periodically deflect by periodically moving or deforming the driving connecting member 12, so that the outgoing light of the display device 100 has three different deflection angles in the first direction A1, where the first direction A1 is the left-right direction of the display panel 2, that is, the first direction is horizontal, the three deflection angles sequentially include a first deflection angle, a second deflection angle, and a third deflection angle from left to right along the first direction A1, the outgoing light sequentially performs periodic transformation at the three different deflection angles, that is, the outgoing light deflects from the first deflection angle to the second deflection angle and then to the third deflection angle, and then deflects to the second deflection angle via the third deflection angle and then returns to the position of the first deflection angle, which is a change period, and the outgoing light of the display device 100 is driven by the driving unit 11 to repeat the three deflection angles for many times, so as to implement periodic transformation. The driving unit 11 can also drive the adjusting and controlling component 10 to deflect in the second direction A2 through the driving connecting component 12, so that the emergent light of the display device 100 also has a plurality of different deflection angles in the second direction A2, where the second direction A2 is the up-down direction of the display panel 2, that is, the longitudinal direction parallel to the display panel 2.

The drive unit 11 may be provided in one or more number.

Referring to fig. 5, in one embodiment, the areas of the light incident surface 1213 and the light emitting surface 1214 of the elastic body 121 are larger than the cross-sectional areas of the display panel 2 and the backlight module 3, so as to ensure that the light incident surface 1213 can still cover the whole backlight module 3 after being translated, or the light emitting surface 1214 can still cover the whole display panel 2 after being translated. For example, as shown in fig. 5, the areas of the light incident surface 1213 and the light emitting surface 1214 of the elastic body 121 are both larger than the cross-sectional areas of the display panel 2 and the backlight module 3, as shown by the dotted line in the figure, when the light incident surface 1213 moves left or right along the first direction A1, the light incident surface 1213 still completely covers the backlight module 3, so that the light emitted from the backlight module 3 can completely enter the dimming assembly 1 through the light incident surface 1213 for adjustment; when the light emitting surface 1214 moves left or right along the first direction A1, the light emitting surface 1214 still completely covers the display panel 2, so that the light adjusted by the dimming component 1 can enter the display panel 2 through the light emitting surface 1214, and it is ensured that light enters all positions of the display panel 2, so as to ensure the display performance of the display device 100.
