Description

Technical Field

[0001] The utility model relates to the technical field of display device accessories, in particular to an anti-peeping protective film layer and a display device. Background Art

[0002] In electronic devices, privacy films can be divided into passive privacy films and active privacy films. The traditional passive privacy film is to add a layer of privacy film on the display surface, but this method will make it impossible to switch modes when privacy protection is not needed, and it will also affect the viewing angle and reduce the screen brightness. The traditional active privacy film adopts a multi-layer privacy film composite structure, and the privacy and normal modes can be switched freely by adjusting the backlight angle. The disadvantage of this structure is that it will increase the overall thickness, and the traditional active privacy film and panel usually adopt an integrated design. This integrated design of the film layer and the display screen cannot be installed later, and the applicable scenarios are limited. Utility Model Content

[0026] To illustrate the anti-peeping protective film layer and the display device provided by the present application, the following is a detailed description in conjunction with the accompanying drawings and the textual description of the embodiments.

[0027] Reference below Figure 1 Describe an anti-peeping protective film layer 100 according to an embodiment of the first aspect of the utility model, such as Figure 1 As shown, the anti-peeping protective film layer 100 includes a substrate layer 110, on which a first protective layer 120, a louver layer 130 and a second protective layer 140 are sequentially arranged, wherein the first protective layer 120, the louver layer 130 and the second protective layer 140 are integrally formed, and the total thickness of the first protective layer 120, the louver layer 130 and the second protective layer 140 is within 100 μm. It can be understood that by setting the overall thickness of the film layer that has an anti-peeping effect within 100 μm, the overall thickness can be reduced. At the same time, the first protective layer 120, the louver layer 130 and the second protective layer 140 are sequentially arranged on the substrate layer 110, so that the anti-peeping protective film layer 100 has a good anti-peeping effect and is suitable for different usage scenarios.

[0028] According to one embodiment of the utility model, Figure 1As shown, the thickness of each of the first protective layer 120, the louver layer 130 and the second protective layer 140 is between 1-6 μm, that is, the individual thicknesses of the first protective layer 120, the louver layer 130 and the second protective layer 140 need to be set between 1-6 μm, so that the overall thickness is kept within a reasonable range to avoid excessive thickness of the overall structure.

[0029] According to one embodiment of the utility model, Figure 1 As shown, the first protective layer 120, the louver layer 130 and the second protective layer 140 have the same thickness. It can be understood that setting the thickness of the first protective layer 120, the louver layer 130 and the second protective layer 140 to be the same can make the manufacturing process more convenient and reduce the overall production cost of the production cycle.

[0030] According to one embodiment of the utility model, Figure 1 As shown, the thickness of the first protective layer 120 and the second protective layer 140 is 2 μm. It can be understood that the thickness of the first protective layer 120 and the second protective layer 140 needs to be greater than 1 μm to ensure that they can play a normal protective role. Considering the thickness of the overall structure, the thickness of the first protective layer 120 and the second protective layer 140 can be set to 2 μm, so as to take into account both lightness and anti-peeping functions.

[0031] According to one embodiment of the utility model, Figure 1 As shown, the first protective layer 120 and the second protective layer 140 are OC adhesive layers.

[0032] According to one embodiment of the utility model, Figure 1 As shown, the shutter layer 130 is a conductive material layer. It can be understood that the shutter layer 130 is made of a conductive material as a medium, and by controlling the change of the electric field passing through the shutter layer 130, a flip angle of 10 to 70 degrees is achieved, thereby achieving adjustment of the viewing angle.

[0033] According to one embodiment of the utility model, Figure 1 As shown, the substrate layer 110 and the first protective layer 120, the louver layer 130 and the second protective layer 140 are an integrally formed structure. It can be understood that by setting the substrate layer 110 and the first protective layer 120, the louver layer 130 and the second protective layer 140 as an integrally formed structure, the overall combination is made more secure.

[0034] According to one embodiment of the utility model, Figure 1As shown, the first protective layer 120 includes at least one first sub-protective layer (not shown in the figure), and / or the second protective layer 140 includes at least one second sub-protective layer (not shown in the figure), that is, the first protective layer 120 can be composed of one or more first sub-protective layers, and similarly, the second protective layer 140 can be composed of one or more second sub-protective layers to meet different usage scenarios.

[0035] According to one embodiment of the utility model, Figure 1 As shown, the base material layer 110 is a glass substrate.

[0036] Reference below Figure 2 A display device 10 according to an embodiment of the second aspect of the present utility model is described. Figure 2 As shown, a display device 10 includes an anti-peeping protective film layer 100, and the anti-peeping protective film layer 100 includes a substrate layer 110, on which a first protective layer 120, a shutter layer 130 and a second protective layer 140 are sequentially arranged, wherein the first protective layer 120, the shutter layer 130 and the second protective layer 140 are integrally formed, and the total thickness of the first protective layer 120, the shutter layer 130 and the second protective layer 140 is within 100μm. It can be understood that by setting the overall thickness of the film layer that has an anti-peeping effect within 100μm, the overall thickness can be reduced. At the same time, the first protective layer 120, the shutter layer 130 and the second protective layer 140 are sequentially arranged on the substrate layer 110, so that the anti-peeping protective film layer 100 has a good anti-peeping effect and is suitable for different usage scenarios.
