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 panel 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. According to the anti-peeping display device, the first cavity 21 is arranged on the shading layer 20, and when non-peeping display is carried out, the fluid 40 is located in the first cavity 21 completely, light emitted from the light emitting layer 10 is not shielded, and compared with the prior art, the anti-peeping display device can improve the problem that the brightness of the anti-peeping display panel is dark.
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 first driving members 50 are plural, and the plural first driving members 50 are disposed corresponding to the first cavity 21. It is understood that the first driving member 50 is disposed opposite to the first cavity 21 in the thickness direction of the light shielding layer 20. The opposite arrangement is that there is an overlap in a certain direction. The first driver 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 first driving member 50 are not limited herein, and it is only necessary to ensure that the first driving member 50 can drive the fluid 40 to flow 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 first driving member 50 is a magnetic body. Specifically, the first driving member 50 is an electromagnet. The first driving member 50 is located at a side of the light shielding layer 20 away from the transparent structure 30. That is, the first driving member 50 is located at the second side 23 of the light shielding layer 20. One first driving member 50 is disposed corresponding to one first cavity 21, and the first driving member 50 has a strip-shaped structure. The first driving member 50 extends along the column direction of the pixel regions 101 and is located between two adjacent columns of the pixel regions 101. After the first driving member 50 is energized, the first 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 first driving member 50 to the fluid 40 can be controlled by controlling the current, so as to determine the rising height of the fluid 40 in the second cavity 31, and further change the size of the peep-proof viewing angle.
In other embodiments, the first driving member 50 may be disposed on a side of the transparent structure 30 away from the light shielding layer 20. Alternatively, the plurality of first driving members 50 may be disposed corresponding to one first cavity 21, and the plurality of first driving members 50 may be disposed at intervals in the extending direction of the transparent structure 30.
The first driving member 50 has a corresponding relationship with the fluid 40. When the fluid 40 is a charged fluid, the first 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, the first driving member 50 drives the fluid 40 to move according to the principle that the magnetic materials repel each other in the same polarity and attract each other in the opposite polarity.

Referring to fig. 1, 5 and 6, fig. 5 is a schematic structural diagram of a fourth embodiment of a display panel provided in the present application, and fig. 6 is a schematic sectional structural diagram at B-B in fig. 5.
The fourth embodiment of the display panel 100 provided in the present application is substantially the same as the first embodiment of the display panel 100 provided in the present application, except that: the display panel 100 further includes a plurality of driving member groups 60.
In the present embodiment, the display panel 100 further includes a plurality of driving element groups 60. The driver group 60 is located in the non-pixel region 102. The driving element group 60 is located at one side of the light shielding layer 20 near the transparent structure 30. That is, the driver set 60 is disposed on the first side 22 of the light shielding layer 20. In the column direction of the pixel region 101, two adjacent driving element groups 60 are located on opposite sides of the pixel region 101, respectively. It is understood that the driver groups 60 are alternately arranged with the pixel regions 101 in the column direction of the pixel regions 101. In the row direction of the pixel region 101, two adjacent driving element groups 60 are respectively located at opposite sides of the transparent structure 30, and are used for controlling deflection of the transparent structure 30. One end of the transparent structure 30, which is in communication with the light shielding layer 20, is flexibly connected with the light shielding layer 20. That is, one end of the transparent structure 30 close to the light shielding layer 20 is fixed to the light shielding layer 20 by a flexible adhesive, and one end of the transparent structure 30 far from the light shielding layer 20 can be deflected left and right in the row direction of the pixel region 101 by the driving of the driving element group 60.

The magnitude of the magnetic field generated between the second driving member 61 and the third driving member 62 can be controlled by controlling the magnitude of the current, thereby changing the magnitude of the angle of the left-right deflection of the transparent structure 30 in the row direction of the pixel region 101; and changing the direction of the current may change the direction in which the transparent structure 30 is deflected in the row direction of the pixel region 101, i.e., whether the transparent structure 30 is deflected to the left or the right in the row direction of the pixel region 101.
It should be appreciated that the fluid 40 also has a correspondence with the second drive member 61 and the third drive member 62. When the fluid 40 is a charged fluid, an electric field is generated between the second driving element 61 and the third driving element 62 to drive the fluid 40 in the second cavity 31 to drive the transparent structure 30 to deflect left and right in the row direction of the pixel region 101. When the fluid 40 is a magnetic fluid, a magnetic field is generated between the second driving element 61 and the third driving element 62 to drive the fluid 40 in the second cavity 31 to drive the transparent structure 30 to deflect left and right in the row direction of the pixel region 101.
