The accommodating layer 20 may be a Black Matrix (BM) or other materials. In this embodiment, the accommodating layer 20 is a black matrix, and mainly plays a role of shading.
Further, the accommodating layer 20 has a first cavity 21. The shape and size of the first cavity 21 are not limited herein, and are selected according to actual needs. The first cavity 21 communicates with one side surface of the accommodating layer 20 in the thickness direction of the accommodating layer 20.
The transparent structures 30 are plural, and the transparent structures 30 are disposed on one side of the accommodating layer 20 along the thickness direction of the accommodating layer 20 and are disposed at a predetermined angle with respect to the accommodating layer 20. The transparent structure 30 has a second cavity 31 in communication with the first cavity 21.

Specifically, the transparent structures 30 extend along the column direction of the display areas 101, and one end of the transparent structures 30 connected to the accommodating layer 20 is located between two adjacent columns of the display areas 101. That is, a transparent structure 30 is disposed between two adjacent columns of display areas 101. It is understood that the extending direction of the transparent structure 30 is parallel to the column direction of the display area 101, and the transparent structures 30 are equally spaced in the row direction of the display area 101. At least one end of the transparent structure 30 exceeds the display area 101 of the edge of the display device 100 in the column direction of the display area 101; or neither end of the transparent structure 30 exceeds the display area 101 at the edge of the display device 100. In the present embodiment, the transparent structure 30 extends beyond the display area 101 at the edge of the display device 100 in the column direction of the display area 101. The length of the transparent structure 30 is not limited herein, and is selected according to practical requirements. In other embodiments, the transparent structures 30 extend along the column direction of the display areas 101, and not all adjacent columns of the display areas 101 are provided with one transparent structure 30 therebetween. That is, one transparent structure 30 is disposed between part of the two adjacent columns of the display areas 101, and one transparent structure 30 is not disposed between part of the two adjacent columns of the display areas 101. It is understood that the extending direction of the transparent structure 30 is parallel to the column direction of the display area 101, and the transparent structures 30 are not equidistantly spaced in the row direction of the display area 101.

Specifically, the transparent structure 30 is disposed obliquely to the left or right with respect to the accommodating layer 20 in the row direction of the display area 101. The preset included angle is 50-70 degrees, namely, the included angle between the transparent structure 30 and the containing layer 20 is 50-70 degrees. One end of the transparent structure 30, which is close to the accommodating layer 20, is fixedly connected with the accommodating layer 20, i.e. the transparent structure 30 is not movable or swings.
In this embodiment, the preset included angle is 60 degrees.
The fluid 40 is at least partially disposed within the first cavity 21. The fluid 40 is movable between the first chamber 21 and the second chamber 31. The volume of the fluid 40 is greater than or equal to the volume of the second cavity 31 and less than or equal to the volume of the first cavity 21, so as to ensure that the fluid 40 can be disposed entirely within the first cavity 21, or the fluid 40 can also fill the second cavity 31. When the fluid 40 is disposed in the first cavity 21, the transparent structure 30 is transparent, and the transparent structure 30 does not play a role in peep prevention, and does not affect the display brightness of the display device 100. The fluid 40 enters the second cavity 31, so that the transparent structure 30 can play a role in shading light to a certain extent, and further play a role in peep prevention. The elevation of the fluid 40 within the second chamber 31 determines the size of the viewing angle. The higher the rise of the fluid 40 in the second chamber 31, the smaller the viewing angle of the peep-proof, i.e. the smaller the viewing angle. In the application, the first cavity 21 is arranged on the accommodating layer 20, so that the fluid 40 is completely positioned in the first cavity 21 during non-peeping display, and the light emitted from the light emitting layer 10 is not blocked.
In this embodiment, the fluid 40 is a magnetic fluid, which is black and magnetic. In other embodiments, the fluid 40 may be other black fluids with magnetic or electrical properties.
The driving members 50 are plural, and the plural driving members 50 are disposed corresponding to the first cavity 21. It is understood that the driving member 50 is disposed opposite to the first cavity 21 in the thickness direction of the accommodating layer 20. The opposite arrangement is that there is an overlap in a certain direction. The driving member 50 is used for driving the fluid 40 from the first cavity 21 into the second cavity 31; or to drive fluid 40 from second chamber 31 into first chamber 21.
The shape and size of the driving member 50 are not limited herein, and it is only necessary to ensure that the driving member 50 drives the fluid 40 between the first cavity 21 and the second cavity 31, thereby changing the distribution of the fluid 40 in the first cavity 21 and the second cavity 31.
In the present embodiment, the driving member 50 is a magnetic body. Specifically, the driving member 50 is an electromagnet. The driving member 50 is located at a side of the accommodating layer 20 away from the transparent structure 30. One driving member 50 is disposed corresponding to one first cavity 21, and the driving member 50 has a strip-shaped structure. The driving member 50 extends along the column direction of the display regions 101 and is located between two adjacent columns of the display regions 101. After the driving member 50 is energized, the driving member 50 can generate a repulsive force on the fluid 40, so that the fluid 40 in the first cavity 21 enters the second cavity 31, thereby playing a peep-proof role. The repulsive force of the driving piece 50 to the fluid 40 can be controlled by controlling the current, so that the ascending height of the fluid 40 in the second cavity 31 is determined, and the peep-proof visual angle is changed; and the transparent structure 30 is obliquely arranged at a preset included angle relative to the accommodating layer 20, so that peep-proof display with a fixed oblique viewing angle can be realized.

Alternatively, the plurality of driving members 50 may be disposed corresponding to one first cavity 21, and the plurality of driving members 50 are disposed at intervals in the extending direction of the transparent structure 30.
The driving member 50 and the fluid 40 have a corresponding relationship. When the fluid 40 is a charged fluid 40, the driving member 50 drives the fluid 40 to move by virtue of the principle that like charges repel each other and opposite charges attract each other. When the fluid 40 is a magnetic fluid 40, the driving member 50 drives the fluid 40 to move by the principle that the magnetic materials repel each other in the same polarity and attract each other in the opposite polarity.
