DETAILED DESCRIPTION

[0088] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0089] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0090] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0091] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0092] It should be noted that, in the absence of conflict, different features in the embodiments of the present application may be combined with each other.

[0093] See also Figure 1 The display panel in the related art includes a display area AA and a non-display area AB. The non-display area AB is the frame area of ​​the display panel. The display panel includes a screen body 1 and a cover plate 4 located on one side of the screen body 1. The screen body 1 and the cover plate 4 are bonded by an optical adhesive layer 2. There are metal traces in the non-display area AB. The greater the density of the light-emitting pixels 9 in the display area AA, the greater the number of metal traces in the non-display area AB. In the non-display area AB, an ink layer 3 is also provided between the screen body 1 and the cover plate 4. The ink layer 3 can block the light emitted by the light-emitting pixels 9 in the display area AA, and can also absorb the light reflected by the metal traces in the non-display area AB.

[0094] However, since the ink layer 3 is first set on the cover plate 4 and then the cover plate 4 and the ink layer 3 are bonded together on the screen body 1 through equipment, setting the ink layer 3 on the cover plate 4 will form a corresponding tolerance, and bonding the cover plate 4 and the ink layer 3 together on the screen body 1 through equipment will also form a corresponding equipment bonding tolerance, so the edge of the ink layer 3 will be larger than the display edge, ultimately making the frame of the display panel wider.

[0095] In order to increase the screen-to-body ratio of the display panel, the border of the display panel needs to be compressed. Figure 2 , Figure 2The black lines in the figure represent light rays. Figure 2 It can be seen from the simulation that when the border of the display panel is compressed to less than or equal to 0.4 mm, due to the above tolerance, the ink layer 3 will not be able to block the light emitted by the light-emitting pixels 9 well enough and will not be able to absorb the light reflected by the metal wiring well enough, which will cause serious light leakage in the border area of ​​the display panel, thereby affecting the display quality of the display panel.

[0096] In view of this, the present embodiment provides a solution that can improve light leakage in the border area of ​​the display panel. The solution provided by the present embodiment is described in detail below.

[0097] See also Figure 3 This embodiment provides a display panel, which includes a display area AA and a non-display area AB surrounding the display area AA. The display panel includes a screen body 1, a cover plate 4 and a shading structure 5.

[0098] The cover plate 4 is located on one side of the screen body 1, the shading structure 5 is located on the side of the screen body 1 away from the display area AA, the shading structure 5 is located in the non-display area AB, the side of the shading structure 5 close to the cover plate 4 extends to contact with the side of the cover plate 4 close to the screen body 1, and the side of the shading structure 5 away from the cover plate 4 extends in a direction away from the cover plate 4.

[0099] The glue dispensing process can be controlled by adjusting the viscosity, pressure and speed of the glue material to set the shading structure 5. The non-display area AB includes the border area of ​​the display panel. The shading structure 5 extends toward the side of the cover plate 4 until it contacts the cover plate 4, and the side of the shading structure 5 away from the cover plate 4 extends in the direction away from the cover plate 4, so that the shading structure 5 fills the gap in the non-display area on the side of the cover plate 4 facing the screen body 1. The shading structure 5 can better block the border area of ​​the display panel, thereby preventing light leakage from occurring in the border area of ​​the display panel.

[0100] In the present embodiment, the ink layer 3 at the cover plate 4 is eliminated, thereby reducing the tolerance of setting the ink layer 3 at the cover plate 4 and reducing the tolerance of fitting the cover plate 4 and the ink layer 3 together on the screen body 1. Therefore, the frame of the display panel can be compressed. While satisfying the requirement of a narrower frame of the display panel, the light leakage phenomenon in the frame area of ​​the display panel can also be improved.

[0101] Based on the above design, in this embodiment, by setting a shading structure 5 on the side of the screen body 1 away from the display area AA, the ink layer 3 in the related technology can be eliminated, and the light on the side of the display panel can be blocked, thereby improving the problem of light leakage in the frame of the display panel while meeting the narrow frame of the display panel, thereby improving the display quality of the display panel.

[0102] In one possible implementation, see Figure 4The screen body 1 includes an array substrate 6, a light-emitting pixel 9 located on one side of the array substrate 6, and a packaging layer 7 located on a side of the light-emitting pixel 9 away from the array substrate 6. The packaging layer 7 extends from the display area AA to the non-display area AB, and the light-emitting pixel 9 is located in the display area AA.

[0103] The display panel further includes a first light shielding layer 8 located on a side of the encapsulation layer 7 close to the cover plate 4 . The first light shielding layer 8 is located in the non-display area AB.

[0104] The array substrate 6 may include a substrate and a plurality of driving units located on one side of the substrate, and each driving unit may include one or more semiconductor switching devices. The semiconductor switching device may be formed by the cooperation of a plurality of film layers in the array substrate 6, for example, the semiconductor switching device may be a thin film transistor formed by the cooperation of a plurality of film layers.

[0105] The first light shielding layer 8 can be coated on the side of the encapsulation layer 7 away from the array substrate 6 by an exposure and development process or an evaporation process or an inkjet printing process. Compared with the related art, the ink layer 3 can be eliminated in this embodiment, and the first light shielding layer 8 can be formed on the side of the encapsulation layer 7 away from the array substrate 6 first, and then the cover plate 4 is arranged on the side of the first light shielding layer 8 away from the array substrate 6. Therefore, the arrangement of the first light shielding layer 8 is not easily affected by the relevant tolerance, so that the width of the frame of the display panel in this embodiment can be more easily reduced.

[0106] See also Figure 5 , Figure 5 The black lines in the figure represent light rays. Figure 5 It can be seen from the simulation diagram that very little light passes through the frame of the display panel. Therefore, the first light shielding layer 8 can further block the light reflected by the surrounding metal wiring and can further improve the phenomenon of light leakage and edge leakage of the frame.

[0107] Preferably, see again Figure 4 , the first light shielding layer 8 extends to contact the light shielding structure 5. In this way, the first light shielding layer 8 and the light shielding structure 5 can be seamlessly connected, so that light is not easy to pass through the gap between the first light shielding layer 8 and the light shielding structure 5, thereby further improving the light leakage phenomenon of the display panel.

[0108] Preferably, the color difference between the first light shielding layer 8 and the light shielding structure 5 is less than or equal to 1. The blackness of the first light shielding layer 8 can be greater than or less than the blackness of the light shielding structure 5, and the color difference between the first light shielding layer 8 and the light shielding structure 5 only needs to be less than or equal to 1. In this way, the integral black effect of the frame area of ​​the display panel can be better satisfied, thereby further improving the display quality of the display panel.

[0109] Preferably, the light absorption of the material of the first light shielding layer 8 is greater than or equal to 5. In this way, the light absorption effect of the first light shielding layer 8 can be ensured, thereby making it more difficult for the frame area of ​​the display panel to leak light.

[0110] Preferably, the material of the first light shielding layer 8 may be a mixture of an organic material and melanin, or may be an inorganic material. Specifically, the material of the first light shielding layer 8 includes at least one of acrylic acid, carbon powder, manganese dioxide or ferrosoferric oxide.

[0111] In one possible implementation, see again Figure 4 , the distance between the orthographic projection of the side of the first shading layer 8 close to the display area AA on the cover plate 4 and the orthographic projection of the side of the display area AA close to the first shading layer 8 on the cover plate 4 is 0.

[0112] Please see again Figure 1 In the related art, due to the influence of the tolerances introduced above, the distance D from the side of the ink layer 3 close to the display area AA to the display area AA is 0.15μm-0.2μm. For example, the distance D can be 0.15μm, 0.17μm, 0.19μm or 0.2μm. In this embodiment, since the first light shielding layer 8 is formed by an exposure and development process or an evaporation process or an inkjet printing process, it is not affected by the corresponding tolerances. Therefore, the distance between the positive projection of the side of the first light shielding layer 8 close to the display area AA on the cover plate 4 and the display area AA can be 0. In this way, the border width of the display panel can be reduced by at least 0.15μm, so that the display panel can better meet the requirements of a narrow border.

[0113] Preferably, see again Figure 4 , along the direction Z perpendicular to the cover plate 4, the thickness L1 of the first light shielding layer 8 ranges from 1.5 μm to 5 μm, for example, the thickness L1 may be 1.5 μm, 2 μm, 3 μm, 4 μm, 4.5 μm or 5 μm, etc. If the thickness L1 is set too large, the thickness of the display panel will increase, and if the thickness L1 is set too small, the light shielding effect of the first light shielding layer 8 will be reduced. Therefore, the thickness L1 is reasonably set, and the thickness of the display panel will not be increased too much while ensuring the light shielding effect of the first light shielding layer 8.

[0114] Preferably, see Figure 6 , the orthographic projection of the first light shielding layer 8 on the cover plate 4 surrounds the orthographic projection of the display area AA on the cover plate 4. The first light shielding layer 8 covers the entire frame, so that the first light shielding layer 8 can play a light shielding effect from different directions, thereby further improving the frame light leakage phenomenon of the display panel.

[0115] In one possible implementation, see Figure 7The display panel further includes a polarizer 10 and a second light shielding layer 11 located between the polarizer 10 and the cover plate 4 , and the second light shielding layer 11 is located in the non-display area AB.

[0116] The polarizer 10 is located on the side of the encapsulation layer 7 away from the array substrate 6, and a second light shielding layer 11 can be set between the cover plate 4 and the polarizer 10. Compared with the related art, the ink layer 3 can be eliminated in this embodiment, and the second light shielding layer 11 can be formed on the side of the polarizer 10 away from the array substrate 6, and then the cover plate 4 is set on the side of the second light shielding layer 11 away from the array substrate 6. Therefore, the setting of the second light shielding layer 11 is not easily affected by the relevant tolerance, so that the width of the frame of the display panel in this embodiment can be more easily reduced. At the same time, the second light shielding layer 11 can block the light reflected by the surrounding metal wiring, and can further improve the light leakage and edge leakage caused by the light passing through the back.

[0117] Preferably, see again Figure 7 , the second light shielding layer 11 extends to contact the light shielding structure 5. In this way, the second light shielding layer 11 and the light shielding structure 5 can be seamlessly connected, so that light is not easy to penetrate through the gap between the second light shielding layer 11 and the light shielding structure 5, thereby further improving the light leakage phenomenon of the display panel

[0118] Preferably, the color difference between the second light shielding layer 11 and the light shielding structure 5 is less than or equal to 1. The blackness of the second light shielding layer 11 can be greater than or less than the blackness of the light shielding structure 5, and the color difference between the second light shielding layer 11 and the light shielding structure 5 only needs to be less than or equal to 1. In this way, the integral black effect of the frame area of ​​the display panel can be better satisfied, thereby further improving the display quality of the display panel.

[0119] Preferably, the transmittance of the material of the second light shielding layer 11 is less than or equal to 0.0001. In this way, the light absorption effect of the second light shielding layer 11 can be ensured, thereby making it more difficult for the frame area of ​​the display panel to leak light.

[0120] Preferably, the material of the second light shielding layer 11 includes black optical glue, and the cover plate 4 can be attached to the side of the polarizer 10 away from the array substrate 6 through the black optical glue. In this way, the second light shielding layer 11 has the functions of light shielding and bonding, and there is no need to use special optical glue to attach the cover plate 4, thereby reducing the thickness and cost of the display panel.

[0121] In one possible implementation, see again Figure 7 , the distance between the orthographic projection of the side of the second shading layer 11 close to the display area AA on the cover plate 4 and the orthographic projection of the side of the display area AA close to the second shading layer 11 on the cover plate 4 is 0.

[0122] Please see again Figure 1In the related art, due to the influence of the tolerances introduced above, the distance D from the side of the ink layer 3 close to the display area AA to the display area AA is 0.15μm-0.2μm. For example, the distance D can be 0.15μm, 0.17μm, 0.19μm or 0.2μm, etc. In this embodiment, since the second light-shielding layer 11 can be first coated on the side of the polarizer 10 away from the array substrate 6 by an inkjet printing process and is not affected by the corresponding tolerances, the distance between the positive projection of the side of the second light-shielding layer 11 close to the display area AA on the cover plate 4 and the display area AA can be 0. In this way, the border width of the display panel in this embodiment can be reduced by at least 0.15μm, so that the display panel can better meet the requirements of a narrow border.

[0123] In one possible implementation, see again Figure 7 The display panel further includes a light-transmitting layer 12 , and the light-transmitting layer 12 is located in the display area AA.

[0124] The material of the light-transmitting layer 12 includes a light-transmitting material, specifically, the material of the light-transmitting layer 12 includes a transparent optical glue. The light emitted by the light-emitting pixels 9 in the display area AA can be irradiated out through the light-transmitting layer 12, so that the normal display of the display panel is not affected.

[0125] In one possible implementation, see again Figure 7 Along the direction Z perpendicular to the cover plate 4 , the thickness L2 of the second light-shielding layer 11 is equal to the thickness L3 of the light-transmitting layer 12 , and the light-transmitting layer 12 and the second light-shielding layer 11 are arranged on the same layer.

[0126] The display area AA can form a light-transmitting layer 12 through an inkjet printing process, and the side of the light-transmitting layer 12 away from the array substrate 6 and the side of the second light-shielding layer 11 away from the array substrate 6 are located in the same plane. In this way, the second light-shielding layer 11 and the light-transmitting layer 12 arranged on the same layer can make the film layer of the display panel smoother.

[0127] Preferably, see again Figure 7 , along the direction Z perpendicular to the cover plate 4, the thickness L2 of the second light shielding layer 11 and the thickness L3 of the light-transmitting layer 12 are both in the range of 1.5 μm-10 μm, for example, the thickness L2 and the thickness L3 can be 1.5 μm, 2 μm, 5 μm, 7 μm, 9 μm, 9.5 μm or 10 μm, etc. If the thickness L2 and the thickness L3 are set too large, the thickness of the display panel will increase, and if the thickness L2 and the thickness L3 are set too small, the light shielding effect of the second light shielding layer 11 will be reduced. Therefore, the thickness L2 and the thickness L3 are reasonably set, and the thickness of the display panel will not be increased too much while ensuring the light shielding effect of the second light shielding layer 11.

[0128] Preferably, see again Figure 7, the edge of the light-transmitting layer 12 contacts the edge of the second light-shielding layer 11. In this way, it is not easy to form a concave structure at the edge of the light-transmitting layer 12 and the edge of the second light-shielding layer 11, so that the flatness of the film layer where the light-transmitting layer 12 and the second light-shielding layer 11 are located can be improved.

[0129] In one possible implementation, see again Figure 7 , the distance D1 from the side of the shading structure 5 away from the display area AA to the display area AA is less than or equal to the distance D2 from the side of the cover plate 4 away from the display area AA to the display area AA. The shading structure 5 does not protrude from the side of the cover plate 4 away from the display area AA, and the width of the frame of the display panel can be reduced without affecting the light leakage effect of the shading structure 5 on the frame of the display panel, so that the display panel can be more easily implemented with a narrow frame.

[0130] In a possible implementation manner, the shading structure 5 includes a first segment 51 and / or a second segment 52 extending toward the display area AA.

[0131] In some embodiments, see Figure 8 The light shielding structure 5 includes a first section 51 extending toward the display area AA, and the first section 51 is located on the side of the screen body 1 close to the cover plate 4. In this way, the first section 51 of the light shielding structure 5 extends toward the display area AA, so that the light shielding structure 5 can be inserted into the film layer of the display panel toward the display area AA, thereby increasing the reliability of the light shielding structure 5 being arranged at the frame position of the display panel, and also improving the light shielding effect of the light shielding structure 5 on the frame.

[0132] In other embodiments, see Fig. 9 The light shielding structure 5 includes a second section 52 extending toward the display area AA, and the second section 52 is located at the side of the screen body 1 away from the cover plate 4. In this way, the second section 52 of the light shielding structure 5 extends toward the display area AA, so that the light shielding structure 5 can be inserted into the film layer of the display panel toward the display area AA, thereby increasing the reliability of the light shielding structure 5 being arranged at the frame position of the display panel, and also improving the light shielding effect of the light shielding structure 5 on the frame.

[0133] In some other embodiments, see Fig.10 The light shielding structure 5 includes a first section 51 and a second section 52 extending toward the display area AA, the first section 51 is located on the side of the screen body 1 close to the cover plate 4, and the second section 52 is located on the side of the screen body 1 away from the cover plate 4. In this way, the first section 51 and the second section 52 of the light shielding structure 5 can both extend toward the display area AA, so that the light shielding structure 5 can be inserted into the film layer of the display panel toward the display area AA, thereby further increasing the reliability of the light shielding structure 5 being set at the frame position of the display panel, and further improving the light shielding effect of the light shielding structure 5 on the frame.

[0134] Preferably, see again Fig.10 The display panel further includes an adhesive layer 13 located on a side of the cover plate 4 close to the screen body 1 , and the first section 51 is disposed on the same layer as the adhesive layer 13 and in contact with the adhesive layer.

[0135] Optionally, the first section 51 is provided in the same layer as the adhesive layer 13 .

[0136] The adhesive layer 13 can adhere and fix the cover plate 4 to the screen body 1, and the edge of the adhesive layer 13 away from the display area AA is retracted relative to the edge of the screen body 1 away from the display area AA, so the first section 51 extends in the direction of the adhesive layer 13 until it contacts the adhesive layer 13 and is arranged in the same layer as the adhesive layer 13. In this way, the reliability of the shading structure 5 being arranged at the frame position of the display panel can be further increased, and the shading effect of the shading structure 5 on the frame can be further improved.

[0137] Preferably, see again Fig.10 , the distance L2 between the orthographic projection of the edge of the adhesive layer 13 away from the display area AA on the cover plate 4 and the orthographic projection of the edge of the screen body 1 away from the display area AA on the cover plate 4 is 0.1mm-0.3mm, for example, the distance L2 can be 0.1mm, 0.15mm, 0.2mm, 0.25mm or 0.3mm, etc. Reasonable setting of the distance L2 can further increase the reliability of the shading structure 5 being set at the frame position of the display panel.

[0138] Preferably, see again Fig.10 The display panel further includes a foam layer 14 located on a side of the screen body 1 away from the cover plate 4 , and the second section 52 is disposed on the same layer as the foam layer 14 and in contact with the foam layer 14 .

[0139] Optionally, the second section 52 is disposed in the same layer as the foam layer 14 .

[0140] The edge of the foam layer 14 away from the display area AA is retracted relative to the edge of the screen body 1 away from the display area AA, so the first section 51 extends in the direction of the adhesive layer 13 to contact the foam layer 14 and is arranged in the same layer as the foam layer 14. In this way, the reliability of the shading structure 5 being arranged at the frame position of the display panel can be further increased, and the shading effect of the shading structure 5 on the frame can be further improved.

[0141] Preferably, see again Fig.10 , the distance L3 between the orthographic projection of the edge of the foam layer 14 away from the display area AA on the cover plate 4 and the orthographic projection of the edge of the screen body 1 away from the display area AA on the cover plate 4 is 0.1mm-0.5mm, for example, the distance L3 can be 0.1mm, 0.2mm, 0.3mm, 0.4mm or 0.5mm, etc. Reasonable setting of the distance L3 can further increase the reliability of the shading structure 5 being set at the frame position of the display panel.

[0142] See also Fig.11 , Fig.11 The black lines in the figure represent light. When the shading structure 5 includes the first segment 51 and the second segment 52, it can be known from the simulation that almost no light leaks out from the frame of the display panel. Therefore, setting the shading structure 5 to include the first segment 51 and the second segment 52 can greatly improve the shading effect of the shading structure 5 on the frame.

[0143] In one possible implementation, see Fig.12 , the orthographic projection of the second light shielding layer 11 on the cover plate 4 surrounds the orthographic projection of the display area AA on the cover plate 4. The second light shielding layer 11 covers the entire frame, so that the second light shielding layer 11 can play a light shielding effect from different directions, thereby further improving the frame light leakage phenomenon of the display panel.

[0144] Preferably, see again Fig.12 , the orthographic projection of the shading structure 5 on the cover plate 4 surrounds the orthographic projection of the display area AA on the cover plate 4 .

[0145] Optionally, the orthographic projection of the shading structure 5 on the cover plate 4 surrounds the orthographic projection of the screen body 1 on the cover plate 4 .

[0146] Optionally, the shading structure 5 is in contact with the peripheral side of the screen body 1 .

[0147] The shading structure 5 covers the entire frame and is closely attached to the peripheral side of the screen body 1 , so that the shading structure 5 can play a shading effect from different directions, thereby further improving the frame light leakage phenomenon of the display panel.

[0148] Preferably, the material of the light shielding structure 5 includes at least one of acrylic acid, silicone, polyurethane or epoxy adhesive. Acrylic acid, silicone, polyurethane or epoxy adhesive has a good light absorption effect, so the light shielding structure 5 is prepared from at least one of acrylic acid, silicone, polyurethane or epoxy adhesive, which can improve the display panel to achieve an extremely narrow display frame without light leakage.

[0149] In one possible implementation, see again Fig.12 The shading structure 5 includes a first portion 53 and a second portion 54 which are arranged opposite to each other along the width direction X of the screen body 1 . The first portion 53 and the second portion 54 are located on both sides of the display area AA. The first portion 53 and the second portion 54 extend along the length direction Y of the screen body 1 .

[0150] The screen body 1 includes a scan line 15, wherein the width direction X of the screen body 1 may be an extension direction of the scan line 15 in the display area AA, and the width direction X of the screen body 1 and the length direction Y of the screen body 1 may be perpendicular to each other. The first portion 53 and the second portion 54 both include a first inclined surface 15 and / or a second inclined surface 16 inclined toward the display area AA.

[0151] When the angles between the first inclined surface 15 and / or the second inclined surface 16 and the direction perpendicular to the cover plate 4 are different, the light leakage of the frame of the display panel is simulated respectively. Before the simulation, the display area AA needs to be blocked to prevent the light emitted by the luminous pixel 9 from radiating out of the display area AA and affecting the simulation result, thereby improving the accuracy of the light leakage simulation of the frame of the display panel.

[0152] In some embodiments, see Fig.13 The first portion 53 and the second portion 54 both include a first inclined surface 15 inclined toward the display area AA.

[0153] See also Fig.14 , Fig.14 The black lines in the figure represent light. When the angle β1 between the first inclined surface 15 and the direction perpendicular to the cover plate 4 is 55°, it can be known from the simulation that a small amount of light leaks out from the frame of the display panel.

[0154] See also Fig.15 , Fig.15 The black lines in the figure represent light. When the angle β1 between the first inclined surface 15 and the direction perpendicular to the cover plate 4 is 52°, according to the simulation, some light leaks out from the frame of the display panel, and when the angle β1 is 52°, the light leaked from the frame of the display panel exceeds the light leaked when the angle β1 is 55°.

[0155] In other embodiments, see Fig.16 , the first portion 53 and the second portion 54 both include a second inclined surface 16 inclined toward the display area AA.

[0156] See also Fig.17 , Fig.17 The black lines in the figure represent light. When the angle β2 between the second inclined surface 16 and the direction perpendicular to the cover plate 4 is 35°, it can be seen from the simulation that a small amount of light leaks out from the frame of the display panel.

[0157] See also Fig.18 , Fig.18 The black lines in the figure represent light. When the angle β2 between the second inclined surface 16 and the direction perpendicular to the cover plate 4 is 36.8°, according to the simulation, some light leaks out from the frame of the display panel, and when the angle β2 is 36.8°, the light leaked from the frame of the display panel exceeds the light leaked when the angle β2 is 35°.

[0158] In some other embodiments, see Fig.19 The first portion 53 and the second portion 54 both include a first inclined surface 15 and a second inclined surface 16 inclined toward the display area AA.

[0159] See also Fig. 20 , Fig. 20 The black lines in the figure represent light. When the angle β1 between the first inclined surface 15 and the direction perpendicular to the cover plate 4 is 55°, and the angle β2 between the second inclined surface 16 and the direction perpendicular to the cover plate 4 is 35°, it can be seen from the simulation that a small amount of light leaks from the frame of the display panel.

[0160] See also Fig.21 , Fig.21 The black lines in the figure represent light. When the angle β1 between the first inclined surface 15 and the direction perpendicular to the cover plate 4 is 52°, and the angle β2 between the second inclined surface 16 and the direction perpendicular to the cover plate 4 is 36.8°, it can be seen from the simulation that part of the light leaks out from the frame of the display panel, and when the angle β1 is 52° and the angle β2 is 36.8°, the light leaked from the frame of the display panel exceeds the light leaked when β1 is 55° and the angle β2 is 35°.

[0161] According to the above simulation, the angle between the first inclined surface 15 and the direction perpendicular to the cover plate 4 is greater than 55°; the angle between the second inclined surface 16 and the direction perpendicular to the cover plate 4 is less than 35°, which can further reduce the light leaking from the frame of the display panel. Therefore, the angle between the first inclined surface 15 and the direction perpendicular to the cover plate 4 is set to be greater than 55°; the angle between the second inclined surface 16 and the direction perpendicular to the cover plate 4 is set to be less than 35°, which can greatly improve the frame light leakage and edge leakage problems of the display panel while meeting the narrow frame of the display panel.

[0162] Preferably, see again Fig.12 The shading structure 5 includes a third portion 55 and a fourth portion 56 which are relatively arranged along the length direction Y of the screen body 1, the third portion 55 and the fourth portion 56 are located on both sides of the display area AA, and the third portion 55 and the fourth portion 56 extend along the width direction X of the screen body 1; the third portion 55 and the fourth portion 56 both include a third inclined surface 17 and / or a fourth inclined surface 18 inclined toward the direction of the display area AA.

[0163] When the angles between the third inclined surface 17 and / or the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 are different, the light leakage of the frame of the display panel is simulated respectively. Before the simulation, the display area AA needs to be blocked to prevent the light emitted by the luminous pixel 9 from radiating out of the display area AA and affecting the simulation, thereby improving the accuracy of the light leakage simulation of the frame of the display panel.

[0164] In some embodiments, see Fig. 22 The third portion 55 and the fourth portion 56 both include a third inclined surface 17 inclined toward the display area AA.

[0165] See also Fig.23 , Fig.23 The black lines in the figure represent light. When the angle β3 between the third inclined surface 17 and the direction perpendicular to the cover plate 4 is 54°, it can be seen from the simulation that a small amount of light leaks out from the frame of the display panel.

[0166] See also Fig.24 , Fig.24 The black lines in the figure represent light. When the angle β3 between the third inclined surface 17 and the direction perpendicular to the cover plate 4 is 52°, according to the simulation, some light leaks out from the frame of the display panel, and when the angle β3 is 52°, the light leaked from the frame of the display panel exceeds the light leaked when the angle β3 is 54°.

[0167] In other embodiments, see Fig.25 The third portion 55 and the fourth portion 56 both include a fourth inclined surface 18 inclined toward the display area AA.

[0168] See also Fig.26 , Fig.26 The black lines in the figure represent light. When the angle β4 between the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 is 36°, it can be seen from the simulation that a small amount of light leaks out from the frame of the display panel.

[0169] See also Fig. 27 , Fig. 27 The black lines in the figure represent light. When the angle β4 between the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 is 37°, according to the simulation, some light leaks out from the frame of the display panel, and when the angle β4 is 37°, the light leaked from the frame of the display panel exceeds the light leaked when the angle β4 is 36°.

[0170] In some other embodiments, see Fig.28 The third portion 55 and the fourth portion 56 both include a third inclined surface 17 and a fourth inclined surface 18 inclined toward the display area AA.

[0171] See also Fig.29 , Fig.29 The black lines in the figure represent light. When the angle β3 between the third inclined surface 17 and the direction perpendicular to the cover plate 4 is 54°, and the angle β4 between the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 is 36°, it can be seen from the simulation that a small amount of light leaks from the frame of the display panel.

[0172] See also Fig.30 , Fig.30 The black lines in the figure represent light. When the angle β3 between the third inclined surface 17 and the direction perpendicular to the cover plate 4 is 52°, and the angle β4 between the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 is 36.8°, it can be seen from the simulation that part of the light leaks out from the frame of the display panel, and when the angle β3 is 52° and the angle β4 is 36.8°, the light leaked from the frame of the display panel exceeds the light leaked when β3 is 54° and the angle β4 is 36°.

[0173] According to the above simulation, the angle β3 between the third inclined surface 17 and the direction perpendicular to the cover plate 4 is greater than 54°; the angle β4 between the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 is less than 36°, which can further reduce the light leaking from the frame of the display panel. Therefore, the angle β3 between the third inclined surface 17 and the direction perpendicular to the cover plate 4 is set to be greater than 54°; the angle β4 between the fourth inclined surface 18 and the direction perpendicular to the cover plate 4 is set to be less than 36°, which can greatly improve the frame light leakage and edge leakage problems of the display panel while meeting the narrow frame of the display panel.

[0174] In summary, in the present application, by setting a shading structure 5 on the side of the screen body 1 away from the display area AA, the ink layer 3 in the related art can be eliminated, and the light on the side of the display panel can be shielded, so that the problem of light leakage from the frame of the display panel can be improved while meeting the narrow frame of the display panel, thereby improving the display quality of the display panel. At the same time, the self-protection performance of the display panel can be improved through the solution of the present application, so that the display panel can meet various environmental testing requirements and the cost of the display panel can be lowered.

[0175] In a possible implementation, the present application further provides an electronic device, the electronic device including the display panel in the present application. The electronic device may include a device with image processing capabilities, such as a server, a personal computer, a laptop computer, etc. Since the electronic device includes the display panel in the present application, the frame of the electronic device is narrower and the frame is not prone to light leakage.
