Referring to fig. 4, in this embodiment, the dimmingcomponent 1 includes a dimmingcomponent 10, a drivingunit 11 and a connectingmember 12, the connectingmember 12 is used for connecting the dimmingcomponent 10 and the drivingunit 11, and the drivingunit 11 drives the dimmingcomponent 10 to periodically deflect by driving the connectingmember 12 to periodically move or deform, so that the emergent light of thedisplay device 100 has N different deflection angles, and the emergent light sequentially and periodically changes at the N different deflection angles. For example, the drivingunit 11 drives the adjustingmember 10 to periodically deflect by periodically moving or deforming thedriving connecting member 12, so that the outgoing light of thedisplay device 100 has three different deflection angles in the first direction A1, where the first direction A1 is the left-right direction of thedisplay 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 thedisplay device 100 is driven by the drivingunit 11 to repeat the three deflection angles for many times, so as to implement periodic transformation. The drivingunit 11 can also drive the adjusting and controllingcomponent 10 to deflect in the second direction A2 through the driving connectingcomponent 12, so that the emergent light of thedisplay 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 thedisplay panel 2, that is, the longitudinal direction parallel to thedisplay panel 2. That is, the drivingunit 11 may drive the adjustingmember 10 to deflect in both the left-right direction and/or the up-down direction of thedisplay panel 2. The drivingunit 11 includes any one of a servo driving motor and a digital electromagnet driver.
Specifically, as shown in fig. 4, the connectingmember 12 includes anelastic body 121, and theelastic body 121 is made of a transparent elastic material, so that light can penetrate through thedimming component 1, and the transmittance of the light can be ensured. For example, theelastic body 121 may be made of transparent rubber or the like. The plurality ofcontrol members 10 are uniformly distributed in theelastic body 121 to ensure uniformity of light passing through the control members. Theelastic body 121 has alight incident surface 1213 and alight emitting surface 1214 which are oppositely disposed, the shapes of thelight incident surface 1213 and thelight emitting surface 1214 may be any shape such as a rectangle or a square, and in this embodiment, the shapes of thelight incident surface 1213 and thelight emitting surface 1214 are substantially rectangular. The drivingunit 11 applies opposite shearing forces to thelight emitting surface 1214 and thelight incident surface 1213 in the first direction A1 to drive theelastic body 121 to deform so as to drive the adjustingmember 10 to deflect, the shearing forces applied to thelight emitting surface 1214 and thelight incident surface 1213 are opposite in direction and equal in magnitude, so as to ensure that thelight emitting surface 1214 and thelight incident surface 1213 of theelastic body 121 can deform in opposite directions, it should be noted that the shearing force only acts to deform thelight emitting surface 1214 and thelight incident surface 1213 in opposite directions, the original shapes and sizes of thelight emitting surface 1214 and thelight incident surface 1213 are not changed, and the shapes and sizes of thelight emitting surface 1214 and thelight incident surface 1213 are still the same. The shape of thedimming device 1 may be set to any shape such as a rectangle, a square, etc. corresponding to the shape of thedisplay panel 2. Thedrive unit 11 may be provided in one or more number.
Referring to fig. 5, in one embodiment, the areas of thelight incident surface 1213 and thelight emitting surface 1214 of theelastic body 121 are larger than the cross-sectional areas of thedisplay panel 2 and thebacklight module 3, so as to ensure that thelight incident surface 1213 can still cover thewhole backlight module 3 after being translated, or thelight emitting surface 1214 can still cover thewhole display panel 2 after being translated. For example, as shown in fig. 5, the areas of thelight incident surface 1213 and thelight emitting surface 1214 of theelastic body 121 are both larger than the cross-sectional areas of thedisplay panel 2 and thebacklight module 3, as shown by the dotted line in the figure, when thelight incident surface 1213 moves left or right along the first direction A1, thelight incident surface 1213 still completely covers thebacklight module 3, so that the light emitted from thebacklight module 3 can completely enter the dimmingassembly 1 through thelight incident surface 1213 for adjustment; when thelight emitting surface 1214 moves left or right along the first direction A1, thelight emitting surface 1214 still completely covers thedisplay panel 2, so that the light adjusted by the dimmingcomponent 1 can enter thedisplay panel 2 through thelight emitting surface 1214, and it is ensured that light enters all positions of thedisplay panel 2, so as to ensure the display performance of thedisplay device 100.
Further, in this embodiment, the connectingmember 12 further includes afirst side plate 122 and asecond side plate 123, theelastic body 121 has afirst side 1211 and asecond side 1212 which are oppositely disposed along the first direction A1, the dimmingassembly 1 includes two drivingunits 11, the two drivingunits 11 are respectively disposed on two sides of theelastic body 121 along the first direction A1, and are respectively disposed at intervals with thefirst side 1211 and thesecond side 1212.

Specifically, thefirst side plate 122 and thesecond side plate 123 can rotate around the firstrotating shaft 124 and the secondrotating shaft 125 along the first direction A1, and can also rotate along the second direction A2, so that the plurality of adjustingmembers 10 in theelastic body 121 can deflect in the first direction A1, and can also deflect in the second direction A2.
