The present application is further described below with reference to the drawings and examples.
As shown in fig. 1, an embodiment of the present application provides a display device including a first polarizer 1, a display panel 2, and a first wave plate 3. The display panel 2 is located on the first polarizer 1, and the first wave plate 3 is located on the display panel 2, i.e. the first wave plate 3 is located on a side of the display panel 2 facing away from the first polarizer 1.
The display panel 2 may be a liquid crystal display panel, and the display panel 2 includes an array substrate 21, a liquid crystal layer 22, and a color film substrate 23. The array substrate 21 is located on the first polaroid 1, the liquid crystal layer 22 is located on one side of the array substrate 21, which is away from the first polaroid 1, the color film substrate 23 is located on one side of the liquid crystal layer 22, which is away from the array substrate 21, and the first wave plate 3 is located on one side of the color film substrate 23, which is away from the liquid crystal layer 22.
The phase difference of the first wave plate 3 is located within a preset phase difference range including all other phase differences except for the common phase difference, which is (2K-1) λ/4, so the preset phase difference range may include all phase differences except for (2K-1) λ/4, K is a positive integer, and λ is a wavelength of light. That is, the first wave plate 3 may be other wave plates than the 1/4 wave plate, such as a 1/8 wave plate, a 3/8 wave plate, and the like. The material of the first wave plate 3 may include cop (cyclic polyolefin) or TAC (Triacetyl Cellulose, cellulose triacetate) or the like.
The light source may be disposed at a side of the first polarizer 1 facing away from the display panel 2, and light of the light source is polarized into linearly polarized light by the first polarizer 1, and the linearly polarized light is emitted after passing through the display panel 2 and forms circularly polarized light by the first wave plate 3. Because there is no other polarizer corresponding to the first polarizer 1 and no other wave plate corresponding to the first wave plate 3, the naked eye of the user can only see chaotic images on the display device, and can not see normal pictures, thereby achieving the purpose of peeping prevention.
The first wave plate 3 in the display device can be wave plates with different phase differences, so that different display devices are formed, namely different display devices can be provided with different wave plates, for example, the wave plate in one display device is a 1/8 wave plate, the wave plate in the other display device is a 3/8 wave plate, each display device can only adopt the corresponding display accessory to watch, the display accessories corresponding to each other cannot be mixed, and the peep preventing effect is effectively improved.
Further, the display device further comprises a protective layer 4, the protective layer 4 being located on the first wave plate 3, i.e. the protective layer 4 is located on the side of the first wave plate 3 facing away from the display panel 2.
Since the thickness of the first wave plate 3 is generally only tens micrometers, the first wave plate is easily damaged by the external environment or hard objects, so that the surface treatment can be performed on the first wave plate 3 or the protective layer 4 can be attached to the first wave plate, thereby improving the hardness and the scratch resistance.
In sum, the embodiment of the application can enable different display devices to have wave plates with different phase differences by setting the first polaroid, the display panel and the first wave plate, wherein the phase difference of the first wave plate is located in a preset phase difference range, namely, different display devices adopt different display accessories to watch, the same display devices are prevented from being designed, and the peeping prevention effect of the display devices is effectively improved.
As shown in fig. 2, the embodiment of the present application provides a display system, which includes a display device 10 and a display accessory 20, wherein the display device 10 is the display device in the above embodiment, and will not be described in detail herein.

The display accessory 20 may be eyeglasses or other devices that are usable by a user to view content displayed on the display device 10.
As shown in fig. 3, the display assembly 20 includes an assembly body 5, a second polarizer 6, and a second wave plate 7. The fitting body 5 may be a transparent carrier, such as a glasses body. The second polarizer 6 is located on the fitting body 5, and when the display fitting 20 is a pair of glasses, the second polarizer 6 is located on the lens, and the second polarizer 6 is located on the outer side of the glasses, i.e. the side facing away from the user wearing the glasses. The second wave plate 7 is located on the second polarizer 6, i.e. the second wave plate 7 is located on the side of the second polarizer 6 facing away from the fitting body 5.
Wherein, the sum of the phase difference of the second wave plate 7 and the phase difference of the matched first wave plate 3 is (2K-1) lambda/2,K, lambda is a positive integer, and lambda is the wavelength of light. For example, the phase difference of the first wave plate 3 is (2K-1) lambda/8, the phase difference of the second wave plate 7 is 3 (2K-1) lambda/8, i.e. the first wave plate 3 can be a 1/8 wave plate, and the second wave plate 7 can be a 3/8 wave plate; the phase difference of the first wave plate 3 is 3 (2K-1) lambda/8, and the phase difference of the second wave plate 7 is (2K-1) lambda/8, i.e. the first wave plate 3 can be a 3/8 wave plate and the second wave plate 7 can be a 1/8 wave plate.
In addition, when the display accessory 20 is parallel to the display device 10, the surface of the second wavelength 7 on the side away from the second polarizer 6 is parallel to the surface of the first wave plate 3 on the side away from the first polarizer 1, the optical axis of the first wave plate 3 is parallel to or perpendicular to the optical axis of the matched second wave plate 7, and the absorption axis of the first polarizer 1 is parallel to or perpendicular to the absorption axis of the matched second polarizer 6.
After the user uses the display accessory, the circularly polarized light emitted by the display device 10 passes through the second wave plate 7 matched with the first wave plate 3 to obtain corresponding linearly polarized light, and then passes through the second polaroid 6 matched with the first polaroid 1 to vanish, so that the user can watch the normal display picture of the matched display device 10 through the display accessory 20.
For example, if the first wave plate 3 is a 1/8 wave plate, the optical axis is 45 degrees, the absorption axis of the first polarizer 1 is 90 degrees, the second wave plate 7 is a 3/8 wave plate, the optical axis is 45 degrees, the absorption axis of the second polarizer 6 is 90 degrees, that is, the first wave plate 3 and the second wave plate 7 may form a 1/2 wave plate, the optical axis of the first wave plate 3 is parallel to the optical axis of the second wave plate 3, the absorption axis of the first polarizer 1 is parallel to the absorption axis of the second polarizer 6, and then the relationship curve (VT curve) between the voltage and the transmittance of the display device 10 using the first wave plate 3 and the first polarizer 1 and the display fitting 20 using the second wave plate 7 and the second polarizer 6 is shown in fig. 4.
For example, if the first wave plate 3 is a 3/8 wave plate, the optical axis is 45 degrees, the absorption axis of the first polarizer 1 is 90 degrees, the second wave plate 7 is a 1/8 wave plate, the optical axis is 45 degrees, the absorption axis of the second polarizer 6 is 90 degrees, that is, the first wave plate 3 and the second wave plate 7 may form a 1/2 wave plate, the optical axis of the first wave plate 3 is parallel to the optical axis of the second wave plate 3, and the absorption axis of the first polarizer 1 is parallel to the absorption axis of the second polarizer 6, then after the display device 10 using the first wave plate 3 and the first polarizer 1 is matched with the display accessory 20 using the second wave plate 7 and the second polarizer 6, the voltage-transmittance relationship curve (VT curve) is shown in fig. 5, and the user can view the normal display picture of the display device 10 through the display accessory 20.
For example, if the first wave plate 3 is a 1/8 wave plate, the optical axis is 45 degrees, the absorption axis of the first polarizer 1 is 90 degrees, the second wave plate 7 is a 1/8 wave plate, the optical axis is 45 degrees, the absorption axis of the second polarizer 6 is 90 degrees, that is, the first wave plate 3 and the second wave plate 7 may form a 1/4 wave plate, the optical axis of the first wave plate 3 is parallel to the optical axis of the second wave plate 3, and the absorption axis of the first polarizer 1 is parallel to the absorption axis of the second polarizer 6, then after the display device 10 using the first wave plate 3 and the first polarizer 1 is matched with the display accessory 20 using the second wave plate 7 and the second polarizer 6, the voltage-transmittance relationship curve (VT curve) is shown in fig. 6, and the user cannot view the normal display image of the display device 10 through the display accessory 20.
For example, if the first wave plate 3 is a 3/8 wave plate, the optical axis is 45 degrees, the absorption axis of the first polarizer 1 is 90 degrees, the second wave plate 7 is a 3/8 wave plate, the optical axis is 45 degrees, the absorption axis of the second polarizer 6 is 90 degrees, that is, the first wave plate 3 and the second wave plate 7 may form a 3/4 wave plate, the optical axis of the first wave plate 3 is parallel to the optical axis of the second wave plate 3, and the absorption axis of the first polarizer 1 is parallel to the absorption axis of the second polarizer 6, then after the display device 10 using the first wave plate 3 and the first polarizer 1 is matched with the display accessory 20 using the second wave plate 7 and the second polarizer 6, the voltage-transmittance relationship curve (VT curve) is shown in fig. 7, and the user cannot view the normal display image of the display device 10 through the display accessory 20.
Therefore, the first wave plate 3 and the second wave plate 7 constitute a (2K-1) lambda/2 wave plate, and a normal display screen of the display device 10 can be viewed through the display accessory 20; the first wave plate 3 and the second wave plate 7 do not constitute the (2K-1) lambda/2 wave plate, and normal display pictures of the display device 10 cannot be viewed through the display accessory 20.
