[0033] Please refer to Figure 1 , Figure 1 A cross-sectional structure schematic diagram of a display panel provided for the first embodiment of the present application.

[0034] As Figure 1 shown, the display panel 1 comprises a display layer 10 and a privacy layer 20 which are sequentially stacked, the display layer 10 is used for image display, the privacy layer 20 is arranged on the side of the display layer 10 in the light emitting direction, and is used for switching between narrow viewing angle and wide viewing angle when the display layer 10 displays images, so as to realize the effect of the privacy screen of the display panel 1.

[0035] Among them, the display panel 1 further comprises a supporting layer 30, the supporting layer 30 is arranged between the display layer 10 and the privacy layer 20, and is used for providing support and buffering effect for the display layer 10 and the privacy layer 20, so as to prevent the display layer 10 or the privacy layer 20 from being deformed when being pressed.

[0036] Specifically, the display layer 10 comprises an array substrate 11, a liquid crystal layer 12 and a color filter substrate 13 which are sequentially stacked, the driving elements provided on the array substrate 11 and the color filter substrate 13 generate corresponding electric field according to data signals (Data), thereby driving the liquid crystal molecules in the display liquid crystal layer 12 to deflect corresponding angles to emit light with corresponding brightness, and then performing image display.

[0037] The privacy layer 20 comprises a first substrate 21, a first liquid crystal layer 22 and a second substrate 23 which are sequentially stacked, wherein the first substrate 21 is adjacent to the side of the display layer 10, the first liquid crystal layer 22 is arranged between the first substrate 21 and the second substrate 23, and the liquid crystal molecules in the first liquid crystal layer 22 rotate different angles under different voltages. By adjusting the voltage between the first substrate 21 and the second substrate 23, the deflection angle of the liquid crystal molecules in the first liquid crystal layer 22 is changed, thereby realizing the switching between narrow viewing angle and wide viewing angle, and then realizing the privacy effect.

[0038] The support layer 30 is provided with a plurality of support structures which are sequentially spaced apart by a predetermined distance, for providing support and buffering effect for the display layer 10 and the privacy layer 20.

[0039] Please refer to Figure 2 , Figure 2 For Figure 1 the planar layout schematic diagram of the support layer.

[0040] As Figure 2 shown, the support layer 30 comprises a first support area 31 and a second support area 32, the first support area 31 is arranged at the planar geometric center area of the side of the support layer 30 facing the privacy layer 20, and the second support area 32 is arranged at the edge position of the side of the support layer 30 facing the privacy layer 20. The first support area 31 is provided with support columns 33 of a first density, and the second support area 32 is provided with support columns 33 of a second density, wherein the first density is greater than the second density, that is, the number of support columns 33 in the first support area 31 per unit area is greater than the number of support columns 33 in the second support area 32. Since the display layer 10 and the privacy layer 20 are prone to deformation under external force, and compared with the edge position, the center position is not supported, and when subjected to external force, the deformation is more serious. By arranging a large number of support columns 33 at the center position of the support layer 30, i.e. the first support area 31, the square deformation of the display layer 10 and the privacy layer 20 when subjected to external force at the center position is effectively avoided, thereby preventing the influence on the display effect and preventing the damage of the substrate.

[0041] In the example embodiment, the cross-sectional area of the support column 33 in the first support region 31 is a first cross-sectional area, and the cross-sectional area of the support column 33 in the second support region 32 is a second cross-sectional area, the first cross-sectional area is greater than the second cross-sectional area. The cross-section of the support column 33 can be obtained by cutting the support column 33 along a direction parallel to the display layer 10 or the privacy layer 20, that is, the cross-section of the support column 33 facing the display layer 10 or the privacy layer and parallel to the display layer 10 is the cross-section of the support column 33, and the area of the cross-section is the cross-sectional area of the support column 33.

[0042] Please refer to Figure 3 , Figure 3 The schematic diagram of the support column layout in 1 is shown.

[0043] As shown in Figure 3 , the liquid crystal layer 12 is provided with a plurality of isolation columns 121, that is, a plurality of isolation columns 121 are arranged between the array substrate 11 and the color film substrate 13, the isolation columns 121 are used to isolate the array substrate 11 and the color film substrate 13, to fill the liquid crystal molecules between the array substrate 11 and the color film substrate 13, and to support the array substrate 11 and the color film substrate 13.

[0044] The support columns 33 in the support layer 30 are arranged one by one corresponding to the isolation columns 121 in the liquid crystal layer 12, that is, the projection of the support column 33 on the color film substrate 13 coincides with the projection of the isolation column 121 on the color film substrate 13 in the vertical direction. The color film substrate 13 is provided with a black matrix region BM and a pixel region (not labeled), the black matrix region BM and the pixel region are arranged in a cross manner, the pixel region is used to emit light of different colors, and the black matrix region BM is used to separate different color pixels to prevent crosstalk when light of different colors passes through the color film substrate 13. The projection of the support column 33 in the support layer 30 on the color film substrate 13 is located in the black matrix region BM or coincides with the black matrix region BM, to prevent the support column 33 from blocking the light emitted by the display layer 10. The diameter of the support column 33 is a first length L1, and the diameter of the isolation column 121 is a second length L2, the first length L1 is less than or equal to the second length L2, that is, the projection area of the support column 33 on the color film substrate 13 is less than or equal to the projection area of the isolation column 121 on the color film substrate 13, to avoid the support column 33 blocking the light emitted by the display layer 10.

[0045] In the example embodiment, the support column 33 can be made of UV hardening resin, or made of heat hardening resin, or made of a mixture of UV hardening resin and heat hardening resin, of course, other materials can also be used according to specific needs, which are not limited in the present application.

[0046] Since the support column 33 is made of UV hardening resin or heat hardening resin, the support column 33 has certain adhesion, and when the support column 33 is arranged on the support layer 30, one end of the support column 33 can be fixed on the display layer 10 or the privacy layer 20, and when the display layer 10 and the privacy layer 20 are laminated, the support column 33 is connected to the privacy layer 20 or the display layer 10 at the same time. Due to the adhesion of the support column 33, the support column 33 has certain fixing ability between the display layer 10 and the privacy layer 20, so that the display layer 10 and the privacy layer 20 are not easy to fall off when subjected to external force, and the firmness between the display layer 10 and the privacy layer 20 is improved.

[0047] Please refer to Figure 4 , Figure 4 for Figure 3 a top view of the support column in the second embodiment of the application.

[0048] As Figure 4 shown, the support column 33 further has a coating layer 34 on the outer surface, and the coating layer 34 is coated on the surface of the support column 33, which is used to absorb moisture and small particle impurities in the air to prevent the water vapor from affecting the light emitted by the display layer 10, thereby affecting the display effect.

[0049] In an exemplary embodiment, the coating layer 34 can be made of graphite, activated carbon or silica gel, or other materials with certain adsorption, and the application does not limit this.

[0050] The coating layer 34 includes a plurality of protrusions 341, which are arranged around the outer side of the support column 33 and formed in a gear shape to increase the contact area of the coating layer 34 with the air, thereby further improving the adsorption of the coating layer 34, so that the water vapor and low-temperature fog in the support layer 30 are at a low level, effectively avoiding the influence of water vapor or low-temperature fog on light.

[0051] The thickness of the coating layer 34, i.e. the length of the protrusion 341, is a third length L3, which can be set according to specific needs, for example, it can be set according to the contact area of the coating layer 34 with the air, and preferably the third length L3 is set to be greater than or equal to 5um, such as 5um, 8um, 10um, etc.

Wherein the projection of each first support member 301 and second support member 302 on the color filter substrate 13 is located in the black matrix region BM or coincides with the black matrix region BM, that is, the light emitted by the display layer 10 can be emitted to the privacy layer 20 through the support layer 30 without being affected by the first support member 301 and the second support member 302.
