[0046] In the related art, the display panel 10 generally includes a display area AA and a dummy area BB (i.e., a dummy area) located at the periphery of the display area AA. When a lens layer is manufactured in the display area AA by printing technology, the moving path of the print head is as shown in FIG. 1. When the print head moves to the dummy area BB, the moving speed of the print head is reduced due to the need to change direction, causing more printing material to accumulate in the dummy area BB, and thus, as shown in FIGS. 2 and 3, the thickness H12 of the dummy lens 32 in the dummy area BB is greater than the thickness H11 of the display lens 31 in the display area AA. Thus, when the micro-lens array is bonded, the dummy lens 32 in the dummy area BB seriously affects the bonding of the display lens in the display area AA, and can easily cause ineffective bonding.

[0047] FIG. 4 shows a partial top view of a display panel 10 according to an embodiment of the present disclosure, FIG. 5 shows a cross-sectional view of the display panel 10 in a display area AA according to an embodiment of the present disclosure, and FIG. 6 shows a cross-sectional view of the display panel 10 in a dummy area BB according to an embodiment of the present disclosure. As shown in FIGS. 4, 5 and 6, the display panel 10 has a display area AA and a dummy area BB located at the periphery of the display area AA. The display panel 10 includes a first substrate 1, a decoration layer 2 located on one side of the first substrate 1, a lens layer 3 located on the side of the decoration layer 2 away from the first substrate 1, and the lens layer 3 includes a display lens 31 located in the display area AA and a dummy lens 32 located in the dummy area BB, the thickness H21 of the display lens 31 is greater than the thickness H22 of the dummy lens 32, and a second substrate 4 located on the side of the lens layer 3 away from the first substrate 1.

[0048] In an embodiment of the present disclosure, by providing the decoration layer 2 on the first substrate 1 and manufacturing the micro-lens array on the decoration layer 2, the thickness H21 of the display lens 31 in the display area AA is greater than the thickness H22 of the dummy lens 32 in the dummy area BB, that is, the surface (the surface away from the decoration layer 2) of the display lens 31 in the display area AA protrudes from the surface (the surface away from the decoration layer 2) of the dummy lens 32 in the dummy area BB, to ensure effective contact of the display lens 31 with the second substrate 4, thereby ensuring effective bonding of the micro-lens array.

[0049] The first substrate 1 and the second substrate 4 can each be a transparent substrate, such as a rigid transparent substrate or a flexible transparent substrate. Taking the rigid transparent substrate as an example, the first substrate 1 can include any one of a glass substrate, a quartz substrate, a ceramic substrate, etc. Taking the flexible transparent substrate as an example, the material of the first substrate 1 can include one or more of polyimide, polyethylene terephthalate, polycarbonate, an organic resin material, etc., and the organic resin material can include epoxy resin, triazine, silicone resin, or polyimide, etc.

[0050] When the first substrate 1 is a transparent substrate, the display panel 10 further comprises a display substrate, such as an OLED (Organic Light-Emitting Diode) display substrate, an LED (Light-Emitting Diode) display substrate, an LCD (Liquid Crystal Display) display substrate, a quantum dot display substrate, etc., which is attached to the first substrate 1, as long as it can emit a light path required for display. The OLED display substrate, the LED display substrate, the LCD display substrate, and the quantum dot display substrate can all refer to related technologies, and the embodiments of the present disclosure do not limit this.

[0051] Of course, in addition to being a transparent substrate as described above, the first substrate 1 can also be an OLED display substrate, an LED display substrate, an LCD display substrate, or a quantum dot display substrate, etc. Taking the first substrate 1 as an OLED display substrate as an example, the first substrate 1 comprises a substrate, an active layer, a gate insulating layer, a gate layer, an interlayer dielectric layer, a source-drain metal layer, a passivation layer, a planarization layer, an anode layer, a light-emitting layer, a cathode layer, and an encapsulation layer, which are sequentially stacked. The modification layer 2 is located on the side of the encapsulation layer away from the substrate.

[0052] In the embodiments of the present disclosure, the modification layer 2 can be a hydrophilic layer or a hydrophobic layer.

[0053] When the modification layer 2 is a hydrophilic layer, the contact angles of the display lens 31 and the virtual lens 32 on the modification layer 2 are both less than 30 degrees, and the contact angle of the display lens 31 on the modification layer 2 is greater than the contact angle of the virtual lens 32 on the modification layer 2, so as to ensure that the display lens 31 has a greater protruding height, thereby ensuring that the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32.

[0054] When the modification layer 2 is a hydrophobic layer, the contact angles of the display lens 31 and the virtual lens 32 on the modification layer 2 are both greater than or equal to 30 degrees and less than 80 degrees, and the contact angle of the display lens 31 on the modification layer 2 is greater than the contact angle of the virtual lens 32 on the modification layer 2, so as to ensure that the display lens 31 has a greater protruding height, thereby ensuring that the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32.

[0055] For example, the modification layer 2 is taken as the hydrophilic layer, the modification layer 2 is processed differently in the display area AA and the virtual area BB, so that the hydrophilicity of the modification layer 2 in the display area AA is worse than that in the virtual area BB, thereby ensuring that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB, and further ensuring that the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32. Alternatively, the virtual area BB of the modification layer 2 can be surface treated, so that the modification layer 2 has a certain roughness in the virtual area BB, thereby ensuring that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB, and further ensuring that the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32. Of course, the modification layer 2 can also be processed by combining the above two methods, that is, the modification layer 2 is processed so that the hydrophilicity of the modification layer 2 in the display area AA is worse than that in the virtual area BB, and at the same time, the modification layer 2 has a certain roughness in the virtual area BB, thereby ensuring that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB, and further ensuring that the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32.

[0056] In some embodiments, the hydrophilicity of the modification layer 2 in the display area AA is less than that in the virtual area BB.

[0057] In this way, the concentration of the polar groups of the modification layer 2 in the display area AA is less than that in the virtual area BB, so that when the lens layer 3 is made on the modification layer 2, the flowability of the display lens 31 in the display area AA is worse than that of the virtual lens 32 in the virtual area BB, that is, the virtual lens 32 in the virtual area BB is easier to flow flat, thereby ensuring that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB.

[0058] The material of the modification layer 2 in the display area AA and the virtual area BB can be the same or different.

[0059] When the materials of the modification layer 2 in the display area AA and the virtual area BB are different, that is, when the modification layer 2 is made on the first substrate 1, different materials can be used to make the modification layer 2 in the display area AA and the virtual area BB, respectively, so as to ensure that the hydrophilicity of the modification layer 2 in the display area AA is less than that in the virtual area BB.

[0060] For example, the material of the modification layer 2 in the display area AA can be one of silicon nitride, organic polyimide fiber and epoxy resin with poor hydrophilicity, and the material of the modification layer 2 in the virtual area BB can be silicon oxide and / or silicon oxynitride. Of course, the materials of the modification layer 2 in the display area AA and the virtual area BB can also be other materials, as long as the hydrophilicity of the modification layer 2 in the display area AA is less than that in the virtual area BB, which is not limited in the embodiments of the present disclosure.

[0061] When the material of the modification layer 2 is the same in the display area AA and the virtual area BB, the hydrophilicity of the display area AA and the virtual area BB is the same, if the lens layer 3 is directly made on the modification layer 2, due to the accumulation of the lens material in the virtual area BB, in the case of the same contact angle, it is easy to cause the contact angle of the virtual lens 32 to be greater than the contact angle of the display lens 31. Therefore, before making the lens layer 3, different treatments can be performed on the modification layer 2 in the display area AA and the virtual area BB to ensure that the hydrophilicity of the modification layer 2 in the display area AA is less than the hydrophilicity in the virtual area BB.

[0062] For example, the modification layer 2 in the display area AA can be hydrophobized, or the modification layer 2 in the virtual area BB can be hydrophilized, or the modification layer 2 in the display area AA can be hydrophobized and the modification layer 2 in the virtual area BB can be hydrophilized. For the hydrophobization of the display area AA, it can be fluorinated treatment, so that the fluorine content of the modification layer 2 in the display area AA is greater than the fluorine content in the virtual area BB; for the hydrophilization of the virtual area BB, it can be ultraviolet irradiation, hydrophilic agent treatment, etc., such as ammonium polyphosphate treatment, so that the ammonium polyphosphate content of the modification layer 2 in the display area AA is less than the ammonium polyphosphate content in the virtual area BB.

[0063] It should be noted that for the case where the material of the modification layer 2 in the display area AA is different from the material of the virtual area BB, the display area AA of the modification layer 2 can also be hydrophobized, and / or the virtual area BB of the modification layer 2 can be hydrophilized, which is not limited by the embodiments of the present disclosure.

[0064] Optionally, as shown in FIG. 7 or FIG. 8, the surface of the modification layer 2 in the virtual area BB has a microstructure 21.

[0065] Wenzel equation considers that the actual contact area of the solid-liquid interface on the rough surface is greater than the apparent contact area, and the liquid can always fill the microgrooves on the rough surface, so the apparent contact angle θ2 on the rough surface and the intrinsic contact angle θ1 of the flat surface satisfy the following relationship: cosθ2=r×cosθ1.

[0066] In the relationship, r is the roughness factor (equal to the ratio of the actual contact area of the solid-liquid interface to the apparent contact area, r>1), and θ1 is less than 30 degrees. It can be seen from the relationship that the larger the value of r is, the smaller the value of θ2 is, that is, the roughening of the surface can make the hydrophilic surface more hydrophilic.

[0067] Therefore, the microstructure 21 provided by the modification layer 2 in the virtual area BB increases the surface roughness in the virtual area BB, and the virtual lens 32 fills the microgrooves on the surface in the virtual area BB to increase the wettability of the virtual lens 32, and the virtual lens 32 has a smaller contact angle, so that the contact angle of the virtual lens 32 is smaller than the contact angle of the display lens 31.

[0068] The microstructure 21 of the modification layer 2 in the virtual area BB can be a groove, a protrusion, or a combination of a protrusion and a groove.

[0069] Optionally, the thickness of the modification layer 2 is greater than or equal to 0.1 microns and less than or equal to 0.5 microns, and the ratio of the thickness of the microstructure 21 to the thickness of the modification layer 2 is greater than or equal to 1 / 4 and less than 1. For example, the thickness of the modification layer 2 is 0.1 microns, 0.2 microns, 0.3 microns, 0.4 microns, 0.5 microns, etc. For example, the microstructure 21 is a groove, as shown in FIG. 7, the ratio of the depth L1 of the groove to the thickness of the modification layer 2 is 1 / 3, 1 / 2, 2 / 3, 3 / 4, etc. For example, the microstructure 21 is a protrusion, as shown in FIG. 8, the ratio of the height L2 of the protrusion to the thickness of the modification layer 2 is 1 / 4, 1 / 3, 1 / 2, etc.

[0070] Optionally, the width of the microstructure 21 and the pitch of the microstructure 21 are greater than or equal to 0.5 microns and less than or equal to 3 microns.

[0071] The width of the microstructure 21 in the first direction X and the pitch of the microstructure 21 can be the same or different. For example, the microstructure 21 is a groove, as shown in FIG. 7, the width d11 of the groove in the first direction X is 0.5 microns, 1.0 microns, 1.5 microns, 2.0 microns, 2.5 microns, 3.0 microns, etc., and the pitch d12 of the groove in the first direction X is 0.5 microns, 1.0 microns, 1.5 microns, 2.0 microns, 2.5 microns, 3.0 microns, etc. For example, the microstructure 21 is a protrusion, as shown in FIG. 8, the width d21 of the protrusion in the first direction X is 0.5 microns, 1.0 microns, 1.5 microns, 2.0 microns, 2.5 microns, 3.0 microns, etc., and the pitch d22 of the protrusion in the first direction X is 0.5 microns, 1.0 microns, 1.5 microns, 2.0 microns, 2.5 microns, 3.0 microns, etc.

[0072] For example, the modification layer 2 is hydrophobic in the display area AA and the virtual area BB, and the hydrophobicity of the modification layer 2 in the display area AA is better than that in the virtual area BB, so that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB, and the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32. The display area AA of the modification layer 2 can also be surface treated to have a certain roughness, so that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB, and the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32. Of course, the modification layer 2 can be treated by combining the above two methods, that is, the modification layer 2 in the display area AA is hydrophobic and has a certain roughness, so that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB, and the thickness H21 of the display lens 31 is greater than the thickness H22 of the virtual lens 32.

[0073] In some embodiments, the hydrophobicity of the modification layer 2 in the display area AA is better than that in the virtual area BB.

[0074] In this way, the concentration of the hydrophobic substance of the modification layer 2 in the display area AA is greater than that in the virtual area BB, so that the display lens 31 in the display area AA is easier to gather when the lens layer 3 is printed on the modification layer 2, so that the contact angle of the display lens 31 in the display area AA is greater than that of the virtual lens 32 in the virtual area BB.

[0075] The material of the modification layer 2 in the display area AA and the virtual area BB can be the same or different.

[0076] When the materials of the modification layer 2 in the display area AA and the virtual area BB are different, the modification layer 2 in the display area AA and the virtual area BB can be made of different materials respectively to ensure that the hydrophobicity of the modification layer 2 in the display area AA is better than that in the virtual area BB.

[0077] When the materials of the modification layer 2 in the display area AA and the virtual area BB are the same, the hydrophobicity of the display area AA and the virtual area BB is the same, and if the lens layer 3 is directly made on the modification layer 2, the thickness H21 of the virtual lens 32 is greater than the thickness H22 of the display lens 31 under the condition that the contact angles are the same. Therefore, the modification layer 2 in the display area AA and the virtual area BB can be treated differently before the lens layer 3 is made to ensure that the hydrophobicity of the modification layer 2 in the display area AA is better than that in the virtual area BB.

[0078] For example, the modification layer 2 in the display area AA can be hydrophilized, or the modification layer 2 in the virtual area BB can be hydrophobized, or the modification layer 2 in the display area AA can be hydrophilized and the modification layer 2 in the virtual area BB can be hydrophobized. The hydrophilization of the display area AA can be ultraviolet irradiation, hydrophilic agent treatment, etc., such as ammonium polyphosphate treatment; the hydrophilization of the virtual area BB can be hydrophobic agent treatment, etc., such as fluorination.

[0079] It should be noted that, in the case that the material of the modification layer 2 in the display area AA is different from the material of the modification layer 2 in the virtual area BB, the display area AA of the modification layer 2 can be hydrophilized, and / or the virtual area BB of the modification layer 2 can be hydrophobized, which is not limited in the embodiments of the present disclosure.

[0080] Optionally, the modification layer 2 has a microstructure 21 on the surface of the display area AA.

[0081] According to the above-mentioned relationship: cosθ2=r×cosθ1, for the originally hydrophobic surface, θ1 is greater than or equal to 30 degrees and less than 80 degrees, at this time, the greater the value of r is, the smaller the value of θ2 is, that is, the surface roughening can make the hydrophobic surface more hydrophobic.

[0082] In this way, when the modification layer 2 is a hydrophobic layer, the microstructure 21 of the modification layer 2 in the display area AA is used to improve the surface roughness of the display area AA, so that the display lens 31 is more easily gathered in the display area AA, so that the display lens 31 has a smaller contact angle, thereby ensuring that the contact angle of the virtual lens 32 is greater than the contact angle of the display lens 31.

[0083] The microstructure 21 of the modification layer 2 in the display area AA can refer to the microstructure 21 in the virtual area BB described above, and details are not repeated here.

[0084] In the embodiments of the present disclosure, the modification layer 2 can be a hydrophilic layer or a hydrophobic layer. When the modification layer 2 is a hydrophobic layer, due to the hydrophobic property of the modification layer 2, when the lens layer 3 is made on the modification layer 2, the printing material will gather on the modification layer 2 to form the display lens 31 in the display area AA and the virtual lens 32 in the virtual area BB, and there will be no printing material leveling and overflow, etc., so the lens layer 3 can be directly made on the modification layer 2.

[0085] When the modification layer 2 is a hydrophilic layer, if the lens layer 3 is directly made on the modification layer 2, the leveling of the printing material in the display area AA is easily caused due to the hydrophilic property of the modification layer 2. Therefore, as shown in FIG. 3, the display panel 10 further comprises a partition layer 5 located on the side of the modification layer 2 away from the first substrate 1; the partition layer 5 comprises a first partition 51 extending at least along the first direction X and a plurality of second partitions 52 extending along the second direction Y and abutting against the first partition 51, and the plurality of second partitions 52 are arranged along the first direction X and each have a display lens 31 between two adjacent second partitions 52.

[0086] In this way, the plurality of second partitions 52 are arranged, and the end of each second partition 52 abuts against the first partition 51 to form a containing groove for containing the printing material, thereby avoiding the leveling of the printing material in the display area AA to ensure the formation of the display lens 31 in the containing groove between two adjacent second partitions 52.

[0087] The first direction X intersects the second direction Y, the first partition 51 can be located on the boundary between the display area AA and the virtual area BB, or on the edge of the display area AA close to the virtual area BB in the first direction X, or on the edge of the virtual area BB close to the display area AA in the first direction X; and the plurality of second partitions 52 are located in the display area AA to facilitate the formation of the display lens 31 in the display area AA through the containing groove between two adjacent second partitions 52.

[0092] Of course, the lens layer 3 can also be other transparent structure layers, such as a resin layer, etc. At this time, a ring of adhesive can be arranged between the first substrate 1 and the second substrate 4 in the virtual area BB, so as to realize the adhesion between the second substrate 4 and the first substrate 1 through the ring of adhesive in the case that the second substrate 4 supports the plurality of display lenses 31, and ensure the reliability of the adhesion of the second substrate 4.

[0093] In the embodiments of the present disclosure, a display device is also provided, which comprises the display panel in the above embodiments.

[0096] In step S110, a first substrate 1 is provided.

[0097] In step S120, a decoration layer 2 is manufactured on one side of the first substrate 1.

[0098] In step S130, a lens layer 3 is manufactured on the side of the decoration layer 2 away from the first substrate 1, the lens layer 3 comprises display lenses 31 in the display area AA and virtual lenses 32 in the virtual area BB, and the thickness of the display lens 31 is greater than the thickness of the virtual lens 32.

[0099] In step S140, a second substrate 4 is provided, and the second substrate 4 is adhered to the side of the lens layer 3 away from the first substrate 1.

[0100] In the embodiments of the present disclosure, by manufacturing the decoration layer 2 on the first substrate 1 and manufacturing the microlens array on the decoration layer 2, the thickness of the display lens 31 in the display area AA is greater than the thickness of the virtual lens 32 in the virtual area BB, that is, the surface (the surface away from the decoration layer 2) of the display lens 31 in the display area AA protrudes from the surface (the surface away from the decoration layer 2) of the virtual lens 32 in the virtual area BB, so as to ensure the effective contact between the display lens 31 and the second substrate 4, thereby ensuring the effective adhesion of the microlens array.

Then, the display area AA is treated to be hydrophobic, and / or the virtual area BB is treated to be hydrophilic. Alternatively, the modification layer 2 is a hydrophilic layer, and the material of the display area AA is the same as the material of the virtual area BB. In this case, the display area AA and the virtual area BB of the modification layer 2 can be made at one time. Then, the display area AA is treated to be hydrophobic, and / or the virtual area BB is treated to be hydrophilic. Then, the surface of the virtual area BB is processed to have the microstructure 21, so as to further optimize the hydrophilicity of the virtual area BB.
