All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Currently, a flexible design of a display panel, especially a flexible design of an OLED (organic light-emitting diode) display panel, such as a display panel with a fixed curvature or capable of being repeatedly folded, is a great development trend. In order to achieve flexibility of the display panel, materials or structures with higher deformability are often used in the design, and the rigidity of the materials or structures is reduced accordingly. And along with more and more functional device, integrated below display panel's supporting layer such as sensor, camera, the supporting layer and be arranged in the opaque rete of the rete between display panel main part and the supporting layer need correspond the design of punching, and because of flexible design demand, the rigidity of supporting layer reduces, change deformation more, cause the supporting layer, the rete that is arranged between display panel main part and the supporting layer punches the regional deformation when laminating with the backplate, cause the impression problem, influence display panel's product quality.
Referring to fig. 1 to fig. 3, an embodiment of the invention provides a display panel 100, which includes a support layer 101, a functional layer 102 on the support layer 101, and a display panel main body 103 on the functional layer 102.
The functional layer 102 includes a transparent material layer 1021 and a first light-shielding layer 1022 located on one side of the transparent material layer 1021.
The first light shielding layer 1022 has a first light hole 105, and an orthogonal projection of the first light hole 105 on the support layer 101 is located in an orthogonal projection of the transparent material layer 1021 on the support layer 101.
In the prior art, a film layer arranged between a support layer and a display panel main body is usually made of black foam, black polyimide or graphite materials. Due to the easy deformation and weak support of these materials, and the easy variability of the materials and/or structures used in the support layer in the prior art, when the support material, the film layer between the support material and the display panel main body are bonded, the deformation is easily generated in the perforated area, thereby causing the marking problem.
According to the invention, through the arrangement of the functional layer, the functional layer comprises the transparent material layer and the first shading layer 1022, the support performance of the film layer between the display panel main body and the support layer in the first light-transmitting hole 105 is improved, and the section difference of the film layer between the display panel main body and the support layer in the first light-transmitting hole 105 is reduced, so that the impression problem caused by the film layer between the display panel main body and the support layer is improved, and the product quality of the display panel is improved.
The technical solution of the present invention will now be described with reference to specific embodiments.
Referring to fig. 1 and fig. 2, in the present embodiment, the first light shielding layer 1022 is located on a side of the transparent material layer 1021 near the support layer 101.
Alternatively, the first light shielding layer 1022 is located on a side of the transparent material layer 1021 near the display panel main body 103.
The light transmittance of the first light-shielding layer 1022 is less than 0.01%. The inventors have studied and found that the material of the first light-shielding layer 1022 is preferably a black ink, the OD (optical density) value of the black ink used for the first light-shielding layer 1022 is greater than or equal to 5, and the adhesion level of the black ink to the substrate in the grid test is greater than or equal to 4B; meanwhile, the difference between the maximum thickness and the minimum thickness of the black ink is less than or equal to 2 micrometers.
The OD of the photoresist ink reaches 5 when the thickness of the photoresist ink is 1.5 μm, the OD of the photoresist ink is greater than 6 when the thickness of the photoresist ink is 2mm, and the adhesion grade of the photoresist ink to the substrate in the bagel test is greater than or equal to 5B, which shows excellent performance, therefore, the material of the first light shielding layer 1022 is more preferably the photoresist ink.
When black ink is used for the first light-shielding layer 1022, the thickness of the first light-shielding layer 1022 may be 1 to 20 micrometers, and the specific thickness setting may be adjusted according to the OD value characteristics of the black ink used.
When black ink is used for the first light-shielding layer 1022, processes such as screen printing, inkjet printing, photoresist ink coating, etc. can be used, and the processes are all easy to implement, for example, adjusting screen design, adjusting inkjet process, etc., to form the first light-transmitting hole 105 on the first light-shielding layer 1022. Therefore, the material of the first light shielding layer 1022 is black ink, which is convenient for mass production of the display panel 100 and improves the production efficiency of the product.
A light transmittance of a material of the transparent material layer 1021 is greater than or equal to 90%; and the degree of color shift of the material of the transparent material layer 1021 is represented by an a value and a b value in a CIE1976 uniform color space diagram, the a value is 1 or less, and the b value is 1 or less; meanwhile, the yellowing degree of the material of the transparent material layer 1021 is represented by a Yellow value (Yellow Index), which is less than or equal to 2.
In addition, the transparent material layer 1021 plays a role of supporting between the support layer 101 and the display panel main body 103, and at the same time, when the display panel 100 is a curvature fixing type display panel or when the display panel 100 is a foldable type display panel, the transparent material layer 1021 should maintain good bending performance. Therefore, the inventor finds in the product verification that the young's modulus of the transparent material layer 1021 is preferably greater than or equal to 100 Mpa; meanwhile, in further product verification, the inventor finds that, in the case of meeting the bending requirement, the young's modulus is larger, which is more beneficial to improve the product performance of the display panel 100 (especially when the display panel 100 is a foldable type display panel), and therefore, the young's modulus of the transparent material layer 1021 is more preferably greater than or equal to 3 Gpa.
The thickness of the transparent material layer 1021 may be between 14 microns and 150 microns, and when the display panel 100 is a curvature fixed type display panel, the thickness of the transparent material layer may be thicker, for example, the thickness may be 100 microns or more; when the display panel 100 is a foldable type display panel, the thickness of the transparent layer material layer needs to be thin, for example, when the bending radius is 1.5 mm, the thickness of the transparent layer material layer 1021 may be less than or equal to 50 micrometers.
The material of the transparent material layer 1021 may be a commercial product meeting the above performance requirements, for example: PET (polyethylene terephthalate) material manufactured by japan dongli, korea SKC, etc., CPI (transparent polyimide) material manufactured by koron, korea SKC, etc., TAC (triacetylcellulose) material manufactured by japan Konica, japan fuji film, etc., PMMA (polymethyl methacrylate) material manufactured by japan dongli, etc., and aramid fiber manufactured by japan dongli, etc. The transparent material layer 1021 is made of commercial products, so that research and development cost is reduced, and the production and the use of products which are rapidly input are facilitated.
The thickness of the functional layer 102 may be the sum of the thicknesses of the first light shielding layer 1022 and the transparent material layer 1021, and may be 15 to 170 micrometers. The thickness of the functional layer 102 is preferably 15 micrometers to 60 micrometers, that is, the total thickness of the first light shielding layer 1022 and the transparent material layer 1021 is preferably 15 micrometers to 60 micrometers. The first light shielding layer 1022 mainly plays a role in light shielding, and when the first light shielding layer 1022 uses black ink, the thickness of the first light shielding layer 1022 can be very thin to meet the light shielding requirement of the first light shielding layer 1022, so that the thickness of the functional layer 102 can be reduced as a whole; moreover, since the ratio of the thickness of the first light shielding layer 1022 to the functional layer 102 is low, after the first light transmitting hole 105 is formed in the first light shielding layer 1022, the step difference of the functional layer 102 caused by the first light shielding layer 1022 is also low, which is more beneficial to the flatness of the functional layer 102, and further improves the mark problem caused by the support layer 101 and the film layer between the support layer 101 and the display panel main body 103.
The thickness of the first light-shielding layer 1022 is smaller than the thickness of the transparent material layer 1021, and preferably, the ratio of the thickness of the first light-shielding layer 1022 to the thickness of the transparent material layer 1021 is 1:9 to 1:19, and may be, for example, 1:10, 1:12, 1:14, 1: 17, and the like. When the thickness of the first light shielding layer 1022 is thicker, that is, the ratio of the thickness of the first light shielding layer 1022 is larger, and if the ratio of the thickness of the first light shielding layer 1022 to the thickness of the transparent material layer 1021 is 1:4, the thickness of the first light shielding layer 1022 is too thick, which causes material waste and affects the overall young's modulus of the functional layer 102, and affects the supporting performance of the functional layer 102; when the thickness of the first light shielding layer 1022 is thinner, if the ratio of the thickness of the first light shielding layer 1022 to the thickness of the transparent material layer 1021 is 1:24, the thickness of the first light shielding layer 1022 is too thin, the light shielding effect of the first light shielding layer 1022 is weakened, the light shielding performance of the functional layer 102 is affected, and the product quality of the display panel 100 is ultimately affected.
The display panel main body 103 comprises a substrate, an array layer 1031 located on the substrate, and a light-emitting device layer 1032 located on the array layer 1031, wherein the array layer 1031 comprises an active layer located on the substrate, a first insulating layer located on the active layer, a gate layer located on the first insulating layer, a second insulating layer located on the gate layer, a source-drain layer located on the second insulating layer, and a third insulating layer located on the source-drain layer, and the light-emitting device layer 1032 comprises an anode layer located on the third insulating layer, a light-emitting material layer located on the anode layer, and a cathode layer located on the light-emitting material layer. The display panel main body 103 further includes a pixel defining layer disposed in the same layer as the light emitting material layer, a polarizing layer 1033 disposed on the light emitting device layer 1032, and a cover plate 1035 disposed on the polarizing layer 1033, and the display panel main body 103 further includes a corresponding adhesive layer 1034 disposed between the polarizing layer 1033 and the cover plate 1035, where the adhesive layer 1034 may be an adhesive material such as an optical adhesive.
Referring to fig. 1 and fig. 2, in some embodiments, when the first light shielding layer 1022 is located on a side of the transparent material layer 1021 near the display panel main body 103, the display panel 100 further includes a back plate 104 located between the display panel main body 103 and the functional layer 102, the first light shielding layer 1022 is attached to the back plate 104, and the transparent material layer 1021 is attached to the support layer 101.
Alternatively, when the first light shielding layer 1022 is located on a side of the transparent material layer 1021 near the support layer 101, the first light shielding layer 1022 is attached to the support layer 101, and the transparent material layer 1021 is attached to the back sheet 104.
At this time, the functional layer 102 is located between the backsheet 104 and the support layer 101, and is directly bonded to the backsheet 104 and the support layer 101 (specifically, the functional layer 102 may be bonded by using an adhesive material such as an optical adhesive), and the functional layer 102 is equivalent to replace a material such as black foam, black polyimide, graphite, and the like, which is conventionally used in the prior art; on this basis, since the first light shielding layer 1022 only occupies a smaller portion of the entire thickness of the functional layer 102, when the first light shielding layer 1022 includes the first light transmission hole 105, the transparent material layer 1021 covers the first light transmission hole 105, and the step difference of the functional layer 102 caused by the first light shielding layer 1022 is much smaller than the step difference caused by punching a film layer formed by an original black foam, black polyimide, graphite, and the like, therefore, by directly attaching the functional layer 102 to the back plate 104 and the support layer 101, the support property and the flatness of the film layer in the punching area before the back plate 104 and the support layer are further improved, the possibility of generating the impression problem in the punching area is reduced, and the product quality of the display panel 100 is improved.
The material of the back plate 104 may be a polyimide material, and the back plate 104 and the display panel main body 103 may be bonded using an adhesive material.
Referring to fig. 3, in some embodiments, the functional layer 102 further includes a second shading layer 1023, and the second shading layer 1023 is located on a side of the transparent material layer 1021 away from the first shading layer 1022.
That is, the first light shielding layer 1022 and the second light shielding layer 1023 are respectively located at two sides of the transparent material layer 1021, when the first light shielding layer 1022 is located at a side of the transparent material layer 1021 close to the back plate 104 and the second light shielding layer 1023 is located at a side of the transparent material layer 1021 close to the support layer 101, the first light shielding layer 1022 and the back plate 104 are attached, and the second light shielding layer 1023 and the support layer 101 are attached; when the first light shielding layer 1022 is located on the side of the transparent material layer 1021 close to the support layer 101 and the second light shielding layer 1023 is located on the side of the transparent material layer 1021 close to the back plate 104, the first light shielding layer 1022 is attached to the support layer 101 and the second light shielding layer 1023 is attached to the back plate 104.
The second light-shielding layer 1023 and the first light-shielding layer 1022 can have the same material selection range and the same thickness setting range. In addition, the second light shielding layer 1023 further has a second light-transmitting hole 107 corresponding to the first light-transmitting hole 105. Preferably, the second light-transmitting hole 107 overlaps the first light-transmitting hole 105 in a top view direction of the display panel 100.
Referring to fig. 1 to 3, in some embodiments, the support layer 101 has a third light hole 106, and the first light hole 105 is located in the third light hole 106 in a top view direction of the display panel 100.
The material of the support layer 101 may be a non-transparent material, for example, the material of the support layer 101 may be copper or stainless steel. Preferably, when the type of the display panel 100 is a display panel with a fixed curvature, the material of the support layer 101 is copper, which can meet the requirement of bending to fix the curvature and play a role of support; when the display panel 100 is a foldable display panel, the support layer 101 is made of stainless steel, so as to meet the requirement of folding, even repeatedly folding, and simultaneously playing a supporting role, and at this time, the support layer 101 needs to be correspondingly designed, for example, a groove or a hole is formed in order to enhance the deformability of the stainless steel.
When the material of the support layer 101 is a non-transparent material, the first light hole 105 corresponds to the third light hole 106 through the arrangement of the third light hole 106, and at this time, in the mobile terminal applying the display panel 100, a functional device is arranged corresponding to the first light hole 105, so that the functional device located below the support layer 101 receives a corresponding signal, for example, when the functional device is a camera or other optical sensing type device, the functional device receives an optical signal passing through the first light hole 105 and the third light hole 106.
In the top view direction of the display panel 100, the first light shielding layer 1022 covers the edge of the third light transmission hole 106, so as to avoid affecting the product appearance and facilitate preventing the user from observing the edge of the third light transmission hole 106 when the user uses the display panel, which affects the user experience.
In the top view direction of the display panel 100, the first light-transmitting holes 105 and the third light-transmitting holes 106 may be disposed in a one-to-one correspondence manner, or a plurality of the first light-transmitting holes 105 may be disposed in a correspondence manner with one of the third light-transmitting holes 106.
In the overlooking direction of the display panel 100, when the first light hole 105 and the third light hole 106 are arranged in a one-to-one correspondence manner, the geometric center of the first light hole 105 may coincide with the geometric center of the third light hole 106, which is beneficial to maximizing the signal receiving efficiency of the functional device, and on the premise that the signal quantity passing through the first light hole 105 and the third light hole 106 is enough for the functional device to realize the function thereof, the areas of the first light hole 105 and the third light hole 106 can be minimized.
In a top view direction of the display panel 100, the first light hole 105 and the third light hole 106 may be circular, and a difference between a radius of the first light hole 105 and a radius of the third light hole 106 is greater than or equal to 50 μm. The inventor has found that, when the first light hole 105 and the third light hole 106 are disposed in a one-to-one correspondence manner, and a difference between a radius of the first light hole 105 and a radius of the third light hole 106 is smaller than 50 micrometers, due to a tolerance problem, the first light shielding layer 1022 may not completely cover an edge of the third light hole 106, which may expose the edge of the third light hole 106, and affect product aesthetics and customer experience. Further, the difference between the radius of the first light-transmitting hole 105 and the radius of the third light-transmitting hole 106 is greater than or equal to 100 micrometers and less than or equal to 200 micrometers. Specifically, when the first light transmission hole 105 and the third light transmission hole 106 are arranged in a one-to-one correspondence, if the third light transmission hole 106 is a circle having a radius of 2mm, the radius of the first light transmission hole 105 may be smaller than or equal to 1.9mm, and meanwhile, in consideration of the problem of the signal receiving amount of the functional device, the radius of the first light transmission hole 105 may be larger than or equal to 1.8 mm.
When the functional layer 102 further includes the second light shielding layer 1023, the sizes, positions and other corresponding relationships of the second light-transmitting holes 107 and the third light-transmitting holes 106 are the same as or similar to the sizes, positions and other corresponding relationships of the first light-transmitting holes 105 and the third light-transmitting holes 106, and thus, the description thereof is omitted.
Referring to fig. 4, in some embodiments, the display panel 100 further includes a transparent filling layer 108 filled in the first light hole 105 and/or the third light hole 106.
When the functional layer 102 further includes the second light shielding layer 1023, the transparent filling layer 108 may be filled in the second light transmitting hole 107.
The material of the transparent filling layer 108 may be the same as or different from the material of the transparent material layer 1021, and the light transmittance of the material of the transparent filling layer 108 is greater than or equal to 90%. The material of the transparent filling layer 108 is used to fill up the step difference caused by the first light hole 105 and/or the third light hole 106, which is beneficial to further enhance the support and flatness of the functional layer 102, reduce the possibility of generating the mark problem in the perforated area, and improve the product quality of the display panel 100.
In the embodiment of the invention, by arranging the functional layer 102, the functional layer 102 includes the transparent material layer 1021 and the first light shielding layer 1022, so that the support property of the film layer between the display panel main body 103 and the support layer 101 in the first light transmission hole 105 is improved, and the section difference of the film layer between the display panel main body 103 and the support layer 101 in the first light transmission hole 105 is reduced, thereby improving the impression problem caused by the film layer between the display panel main body 103 and the support layer 101, and improving the product quality of the display panel 100.
Referring to fig. 5, an embodiment of the present invention further provides a mobile terminal 10, including any one of the display panels 100 and a terminal main body 200, where the terminal main body 200 and the display panel 100 are combined into a whole.
For a specific structure of the display panel 100, please refer to any of the embodiments of the display panel and fig. to fig., which are not described herein again.
