Example two
Based on the above inventive concept, the embodiment of the present invention further provides a display device, which is different from the display device described above in that the specific implementation manner of the viewing angle switching module is different, and the same parts are not repeated. Fig. 3 is a schematic structural diagram of another display device according to an embodiment of the present invention. Fig. 4 is a schematic structural diagram of a viewing angle switching module in the display device shown in fig. 3 in a first state. Fig. 5 is a schematic structural diagram of a viewing angle switching module in the display device shown in fig. 3 in a second state. Referring to fig. 3 to 5, and to fig. 1 and 2, the display device includes a backlight module 10 and a display panel 20, which are stacked, and further includes: the peep-proof film 30 is positioned between the backlight module 10 and the display panel 20; a viewing angle switching module 40 located on one side of the privacy film 30 facing the display panel 20; the viewing angle switching module 40 includes a plurality of first electrodes 431 and a plurality of second electrodes 432, a hydrophobic layer 433, a polar solution 435, and a non-polar solution 434, which are located in the same horizontal plane; when a preset voltage difference exists between the first electrode 431 and the second electrode 432, the polar solution 435 pushes the non-polar solution 434 to make the non-polar solution 434 shrink and break to form particles, when no voltage difference exists between the first electrode 431 and the second electrode 432, the polar solution 435 and the non-polar solution 434 are laid on the hydrophobic layer 433, and the non-polar solution 434 is located between the hydrophobic layer 433 and the polar solution 435.
Specifically, as shown in fig. 4, when the viewing angle switching module 40 is in the first state, no voltage is applied to the first electrode 431 and the second electrode 432, the voltage difference between the two is 0, the wettability of the polar solution 435 on the hydrophobic layer 433 is non-wetting, and both the polar solution 435 and the non-polar solution 434 are spread on the hydrophobic layer 433. The light with small angle transmitted from the peep-proof film 30 passes through the hydrophobic layer 433, the non-polar solution 434 and the polar solution 435 in sequence and then is emitted out, and is still the light with small angle, so that the light with small angle provides the light source for the display panel 20, and the display device presents a narrow viewing angle mode. As shown in fig. 5, when the viewing angle switching module 40 is in the second state, voltages with different potentials are applied to the first electrode 431 and the second electrode 432, so that when a preset voltage difference exists between the first electrode 431 and the second electrode 432, the wettability of the polar solution 435 on the hydrophobic layer 433 changes from non-wetting to wetting, and the polar solution 435 pushes the non-polar solution 434 to approach the hydrophobic layer 433, so that the shape of the non-polar solution 434 changes to become a plurality of irregular particles. When the light of the small angle that is transmitted from the peep-proof film 30 is irradiated to the non-polar solution 434 and the polar solution 435, because the non-polar solution 434 is in the shape of irregular particles, the light can continuously pass through two media with different refractive indexes, and the light can be refracted, reflected and scattered at the same time, so that the optical diffusion effect is caused, the light of the small angle can be effectively scattered to be changed into the light of the large angle, so that the light of the large angle provides a light source for the display panel 20, and the display device presents a wide view angle mode.
Specifically, the specific value of the preset voltage difference can be set by one skilled in the art according to actual situations, and is not limited herein. Specifically, the materials of the hydrophobic layer 433, the polar solution 435, and the non-polar solution 434 may be selected by those skilled in the art according to practical situations, and are not limited herein. Alternatively, the hydrophobic layer 433 comprises a resin, the polar solution 435 comprises water, and the non-polar solution 434 comprises an oil. It can be understood that the response time required for the water to change from non-wetting to wetting is short, typically around 10ms, and therefore, the problem of switching the wide and narrow viewing angles for too long time does not occur.
The display device provided by the embodiment of the utility model is additionally provided with the visual angle switching module, so that when the visual angle switching module is in the first state, the visual angle switching module can directly emit the light transmitted from the peep-proof film to the display panel to realize narrow visual angle display; when visual angle switching module is under the second state, it can carry out diffusion treatment with the light that sees through from the peep-proof membrane to break up the light of small angle and become the light of large angle, then exit to display panel, show with realizing wide visual angle, solve the problem that the consumption is high among the prior art, realize that wide and narrow visual angle freely switches, and the effect of reduction power consumption.

The preset voltage difference is greater than or equal to a voltage difference threshold value.
