The technical solution of the present application will now be described with reference to specific embodiments. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
In this embodiment, the display panel 10 is a flexible display panel 10, such as an OLED panel, a Mini-LED panel, a Micro-LED panel, and the like.
In this embodiment, the display panel 10 may be a transparent display panel 10, or may be any display panel 10 that needs to implement a light-transmitting function, such as a display panel applied to an under-screen camera, and the application is not limited thereto.
In this embodiment, the material of the substrate layer 2110 can be polyimide, polycarbonate, polyethersulfone, polyethylene terephthalate, polyethylene naphthalate, polyarylate, or glass fiber reinforced plastic.
In this embodiment, the light-transmitting hole 220 may be a hole with any shape, including a circle, an ellipse, a rectangle, a square, a cross, and the like, which is not limited in this application.
In this embodiment, the display panel 10 further includes a plurality of electrical connection structures including metal lines electrically connecting the light emitting units 110, and the adjacent island-shaped structures 100 are connected by the plurality of electrical connection structures.
In this embodiment, the substrate layer 2110 may be difficult to peel off from the substrate due to various reasons such as uneven laser energy distribution or different acting force between the substrate layer 2110 and the substrate in the laser peeling process of the flexible display panel 10. The pulling during the peeling process may easily cause the package structure 300 to break. Since the thickness of the film at the light-transmitting hole 220 is the thinnest, the pulling easily causes cracks in the package structure 300 at the light-transmitting hole 220.
In the display panel 10 of the present application, the first groove 221 is disposed in the same layer as the substrate layer 2110, and the second groove 222 is disposed in the same layer as one of the insulating layers 2120.
In this embodiment, referring to fig. 2 to 3, when the package structure 300 at the light-transmitting hole 220 cracks due to pulling, the first groove 221 and the substrate layer 2110 are disposed on the same layer, and the pulling force at the corner a of the first groove 221 is not easily transmitted upwards due to the fact that the first groove 221 has a different aperture from the light-transmitting hole 220 in the upward extending direction, so that the package structure 300 is terminated at the corner a. Thus, the package structure 300 located above the first groove 221 can be prevented from being damaged.
In this embodiment, referring to fig. 2, the second groove 222 is located in the plurality of insulating layers 2120, the second groove 222 may be disposed in the same layer as any one of the plurality of insulating layers 2120, and the second groove 222 may also simultaneously penetrate two or more insulating layers 2120, which is not limited in this application.
In the embodiment, by disposing the first groove 221 and the substrate layer 2110 in the same layer, and disposing the second groove 222 and the plurality of insulating layers 2120 in the same layer, when a crack occurs in the package structure 300 at the first groove 221 during the peeling process, the crack may terminate at the corner a of the first groove 221, so as to prevent the package structure 300 above the first groove 221 from being damaged. By disposing the second groove 222 in the plurality of insulating layers 2120, the second groove 222 can be further away from the first groove 221, so that the package structure 300 at the second groove 222 is not affected by cracks generated by the package structure 300 at the first groove 221.
In this embodiment, the substrate layer 2110 may be difficult to peel off from the substrate due to various reasons such as uneven laser energy distribution or different acting force between the substrate layer 2110 and the substrate in the laser peeling process of the flexible display panel 10. The pulling during the peeling process is likely to cause the package structure 300 to break. Since the thickness of the film at the light-transmitting hole 220 is the thinnest, the pulling easily causes cracks in the package structure 300 at the light-transmitting hole 220.
In the display panel 10 of the present application, please refer to fig. 4 to 5, the substrate layer 2110 includes a first substrate 2111 and a second substrate 2112 located above the first substrate 2111, the first substrate 2111 is disposed away from the light emitting unit 110, the second substrate 2112 is disposed close to the light emitting unit 110, a barrier layer 2113 is disposed between the first substrate 2111 and the second substrate 2112, and the barrier layer 2113 includes a barrier hole penetrating through the barrier layer 2113; the blocking hole coincides with the center of the light hole 220, the diameter of the circumscribed circle of the blocking hole is smaller than that of the circumscribed circle of the light hole 220, the first groove 221 and the first substrate 2111 are arranged on the same layer, and the second groove 222 and the second substrate 2112 are arranged on the same layer.
In this embodiment, the barrier layer 2113 may be Al2O3(aluminum oxide), TiO2(titanium oxide), SiNx (silicon nitride), SiCNx (silicon carbide nitride), SiOx (silicon oxide).
In this embodiment, the barrier layer 2113 can be used for blocking the water and oxygen from entering the display panel 10 from the substrate layer 2110 side.
In this embodiment, the blocking hole coincides with the center of the light hole 220, and the diameter of the circumscribed circle of the blocking hole is smaller than the diameter of the circumscribed circle of the light hole 220. Preferably, the blocking hole has the same shape as the light-transmitting hole 220.
In this embodiment, the barrier layer 2113 completely covers the first substrate 2111.
In this embodiment, the first groove 221 and the first substrate 2111 are disposed in the same layer, and the second groove 222 and the second substrate 2112 are disposed in the same layer, so that after the package structure 300 at the first groove 221 cracks in the lift-off process, the package structure 300 at the second groove 222 and the package structure 300 at the barrier layer 2113 can still form a hermetic package. Meanwhile, since the joint of the second groove 222 and the barrier layer 2113 has a plurality of corners a, the encapsulation structure 300 is extended, and the path of water and oxygen entering the inside of the display panel 10 along the gap between the barrier layer 2113 and the encapsulation structure 300 is increased, so that the risk of water and oxygen entering the inside of the display panel 10 is reduced, and a better encapsulation effect can be achieved.
In the display panel 10 of the present application, the light-transmitting body 210 further includes a shielding layer 2114 provided between the first substrate 2111 and the second substrate 2112; the shielding layer 2114 includes a shielding hole penetrating through the shielding layer 2114, and the shielding hole coincides with the light transmitting hole 220.
In this embodiment, the blocking layer 2114 may be an oxide including indium tin oxide, indium zinc oxide, or the like.
In this embodiment, the shielding hole coincides with the center of the light hole 220, and the shielding hole is located in the light hole 220.
In this embodiment, the shielding layer 2114 is disposed around the light hole 220, and the shielding layer 2114 may be any shape with a shielding hole in the middle.
In this embodiment, the shape of the shielding hole includes a circle, an ellipse, a rectangle, a square, a cross, and the like, which is not limited in this application. Preferably, the blocking hole has the same shape as the blocking hole.
In this embodiment, referring to fig. 4 to 5, the blocking layer 2114 may be located above the blocking layer 2113, or below the blocking layer 2113.
In this embodiment, the blocking hole coincides with the center of the blocking hole.
In this embodiment, when the first groove 221 is disposed on the first substrate 2111 and the second groove 222 is disposed on the second substrate 2112, the shielding layer 2114 is disposed on one side of the barrier layer 2113, so that the distance between the first groove 221 and the second groove 222 can be increased, and the possibility that a crack generated by the package structure 300 in the first groove 221 extends to the package structure 300 in the second groove 222 is reduced. Meanwhile, the distance between the first groove 221 and the second groove 222 is increased by increasing the thickness of the blocking layer 2113 instead of increasing the thickness of the blocking layer 2114, so that the effect of increasing the distance can be achieved without increasing the thickness of the blocking layer 2113. Because, when the thickness of the barrier layer 2113 is increased, the bending performance of the flexible display panel 10 may be decreased. Therefore, by providing the blocking layer 2114 at the light transmission hole 220, an adverse effect of an increase in thickness of the blocking layer 2113, which leads to a decrease in bending performance of the flexible display panel 10, is avoided.
In this embodiment, by disposing the shielding layer 2114 between the first substrate 2111 and the second substrate 2112, and the shielding hole coincides with the center of the light-transmitting hole, the possibility that the crack generated by the package structure 300 at the first groove 221 extends to the package structure 300 at the second groove 222 can be reduced; at the same time, the adverse effect of the barrier layer 2113 increasing in thickness, which leads to a decrease in the bending performance of the flexible display panel 10, is avoided.
In the display panel 10 of the present application, referring to fig. 4 to 5, the diameter of the circumcircle of the shielding layer 2114 is greater than the diameter of the circumcircle of the first groove 221 and the second groove 222.
In this embodiment, the diameter of the circumcircle of the shielding hole is smaller than the diameter of the circumcircle of the first groove 221 and the second groove 222.
In this embodiment, the inner wall of the first groove 221 may be sloped, that is, the diameter of the circumscribed circle of the first groove 221 gradually increases in a direction approaching the light emitting unit 110.
In this embodiment, the inner wall of the second groove 222 may be sloped, that is, the diameter of the circumcircle of the second groove 222 gradually increases in a direction approaching the light emitting unit 110.
In this embodiment, the diameter of the circumcircle of the shielding layer 2114 is greater than the diameter of the circumcircle of the first groove 221 and the second groove 222, that is, the inner wall of the shielding layer 2114 exceeds the light-transmitting hole 220, and the outer wall of the shielding layer 2114 is disposed in the substrate layer 2110.
In this embodiment, the diameter of the circumcircle of the shielding layer 2114 is set to be larger than the diameter of the circumcircle of the first groove 221 and the second groove 222, so that the coverage area of the encapsulation structure 300 at the first groove 221 and the second groove 222 on the shielding layer 2114 is increased, and a better encapsulation effect is achieved.
In this embodiment, the substrate layer 2110 may be difficult to peel off from the substrate due to various reasons such as uneven laser energy distribution or different acting force between the substrate layer 2110 and the substrate in the laser peeling process of the flexible display panel 10. The pulling during the peeling process is likely to cause the package structure 300 to break. Since the thickness of the film at the light-transmitting hole 220 is the thinnest, the pulling easily causes cracks in the package structure 300 at the light-transmitting hole 220. Therefore, when the diameter of the circumcircle of the first groove 221 is smaller, the strength of the substrate layer 2110 here is correspondingly larger, so that the possibility of cracks occurring in the package structure 300 here can be reduced.
In the display panel 10 of the present application, a diameter of a circumscribed circle of the first groove 221 is smaller than or equal to a diameter of a circumscribed circle of the second groove 222.
In the embodiment, by setting the diameter of the circumscribed circle of the first groove 221 arranged on the substrate layer 2110 to be smaller than the diameter of the circumscribed circle of the second groove 222, the strength of the substrate layer 2110 at the first groove 221 can be enhanced as much as possible, and the possibility of cracks occurring in the package structure 300 at the first groove 221 is reduced. Meanwhile, the contact area between the package structure 300 and the shielding layer 2114 in the second groove 222 can be increased as much as possible, and the reliability of the package is improved.
In the display panel 10 of the present application, referring to fig. 2 to 5, the light holes 220 penetrate through the substrate layer 2110 and the plurality of insulating layers 2120.
In this embodiment, the light hole 220 penetrates the substrate layer 2110 and the plurality of insulating layers 2120, so that the transmittance of light is increased as much as possible.
In this embodiment, the inner wall of the light-transmitting hole 220 may be sloped such that the diameter of the circumscribed circle of the light-transmitting hole 220 gradually increases in a direction approaching the light-emitting unit 110. With the above arrangement, the transmittance of the light-transmitting body 210 can be further improved.
In this embodiment, the light hole 220 may penetrate through the insulating layer 2120 and a portion of the substrate layer 2110, so as to increase the strength of the substrate layer 2110 and reduce the risk of the package structure 300 at the first groove 221 being pulled to crack.
In this embodiment, the light-transmitting holes 220 are formed to penetrate the substrate layer 2110 and the insulating layers 2120, so that the transmittance of light can be increased as much as possible.
In the display panel 10 of the present application, the encapsulation structure 300 includes at least one organic layer 301 and at least one inorganic layer 302, and the encapsulation structure 300 extends toward the light emitting unit 110 and covers the light emitting unit 110.
In the present embodiment, referring to fig. 2 to 5, the package structure 300 covers the light emitting unit 110 and the light hole 220, and a portion of the package structure 300 located in the light hole 220 is tightly attached to an inner wall of the light hole 220.
In this embodiment, the package structure 300 includes at least one organic layer 301 and at least one inorganic layer 302, the organic layer 301 and the inorganic layer 302 are stacked, and positions of the organic layer 301 and the inorganic layer 302 may be interchanged, that is, the package structure 300 near the light emitting unit 110 may be the organic layer 301 or the inorganic layer 302.
