The applicant provides a solution to the problems of the prior art through intensive research.
In an embodiment of the present application, please refer to fig. 1 to 3, wherein fig. 1 is a schematic diagram of a display panel according to an embodiment of the present application, fig. 2 is a cross-sectional view of the display panel along the direction AA 'according to the embodiment of the present application, and fig. 3 is a cross-sectional view of the display panel along the direction BB' according to the embodiment of the present application. As shown in fig. 1 to 3, the display panel 001 includes a protective layer 10, a conductive film 20, and external electronic devices 30 disposed therebetween.
Further, with continued reference to fig. 1-3, the protection layer 10 and the conductive film 20 are disposed on the backlight surface of the display panel 001, and the conductive film 20 is disposed on a side of the protection layer 10 away from the backlight surface. The backlight surface of the display panel 001 is opposite to the light-emitting surface of the display panel.
Specifically, with continued reference to fig. 2 and fig. 3, the protection layer 10 at least includes a first conductive portion 10a, and the first conductive portion 10a includes a first edge 101. The conductive film 20 includes a second edge 201, and the first edge 101 of the first conductive portion 10a in the protective layer 10 is in contact with the second edge 201 of the conductive film 20.
More specifically, the external electronic device 30 is disposed between the first conductive portion 10a and the conductive film 20, and the first edge 101 of the first conductive portion 10a in the protective layer 10 at least partially surrounds the projection of the external electronic device 30 on the protective layer 10, and the second edge 201 of the conductive film 20 at least partially surrounds the external electronic device 30.
It should be noted that the external electronic device 30 is disposed between the first conductive portion 10a of the protective layer 10 and the conductive film 20, and the first edge 101 and the second edge 201, which are in contact with each other, at least partially surround the projection of the external electronic device 30 on the protective layer 20 and the external electronic device 30, respectively, and then the external electronic device 30 is disposed in the region surrounded by the first edge 101 in the protective layer 10 and the region protected by the second edge 201 in the conductive film 20. Specifically, it can be seen from fig. 2 and 3 that the first conductive portion 10a of the protective layer 10 and the conductive film 20 form a cavity, and the external electronic device 30 is specifically disposed in the cavity.
Since the first conductive part 10a and the conductive film 20 forming the cavity for accommodating the external electronic device 30 have conductivity, the cavity formed by the first conductive part 10a and the conductive film 20 has a good electromagnetic shielding effect, and can effectively shield the interference of external electromagnetic signals to the external electronic device 30 and the interference of electromagnetic signals generated by the external electronic device 30 to signals in the display panel 001.
In one embodiment of the present application, please refer to fig. 1, the external electronic device 30 is electrically connected to the light-emitting side of the display panel 001. Specifically, the display panel 001 further includes an array substrate 50 and a flexible substrate 40, the external electronic device 30 is disposed on the flexible substrate 40, and the flexible substrate 40 is bound to the array substrate 50. That is, the external electronic device 30 disposed in the cavity is electrically connected to the array substrate 50 of the display panel 001 through the flexible base material 40. At this time, the external electronic device 30 is disposed in the cavity, and an opening is required to be disposed on the cavity, so that the flexible substrate 40 is connected to the external electronic device 30 and the array substrate 50 through the opening. More specifically, an opening may be provided in the conductive film 20 so that the cavity formed by the conductive film 20 and the protective layer 10 has an opening. In addition, when the array substrate 50 is bound by the flexible substrate 40, the area of the binding position between the array substrate 50 and the flexible substrate 40 is small, which is beneficial to the realization of a narrow frame or an ultra-narrow frame of the display panel 001.
Specifically, in one embodiment of the present application, the external electronic device may be an IC. More specifically, the IC may be a driving IC of the display panel 001, and may provide a display signal to the display panel 001, receive and process an instruction in the display panel 001, and control the display panel 001 to implement a corresponding reaction, such as receiving the display signal and implementing a display function, receiving and recognizing a touch signal, and making a corresponding reaction. Since the IC is one of the main devices determining the performance of the display panel 001, the IC is disposed in the cavity formed by the first conductive portion 10a of the passivation layer 10 and the conductive film 20, so that the display and touch performance of the display panel can be effectively prevented from being interfered by external electromagnetic signals.
In an embodiment of the present application, the protective layer 10 may specifically include ink, and the ink may effectively prevent the array substrate 50 of the display panel 001 from being scratched. Meanwhile, in order to ensure that the first conductive portion 10a of the protective layer 10 has conductivity, the first conductive portion 10a includes conductive particles. That is, the first conductive portion 10a is formed by doping conductive particles at a specific portion of the protective layer 10, and more specifically, at a specific portion of the ink layer. Therefore, a new film layer is not required to be added, the conductive particles are doped in the ink, the protective performance of the ink can be utilized to protect the display panel 001, the first conductive part 10a of the protective layer 10 can have conductive performance, and meanwhile, the doping process for doping the conductive particles in the protective layer 10 is simple and easy to achieve.
Specifically, the conductive particles doped in the protective layer 10 may include at least one of copper powder, aluminum powder, and silver powder. The conductive particles are doped in the protective layer 10, so that the first conductive portion 10a of the protective layer has good conductivity.
In one embodiment of the present application, the conductive film 20 may be at least one of a metal foil and a conductive cloth. The metal foil and the conductive cloth have soft texture, and can be effectively bonded to the first conductive part 10a of the protective layer 10, thereby easily forming a cavity for accommodating the external electronic device 30.
Referring to fig. 1-3, in an embodiment of the present disclosure, the external electronic device 30 may be disposed on the protection layer 10 and located on a side of the protection layer 10 away from the light exit surface. That is, the external electronic device 30 may be disposed directly on the protective layer 10 with the flexible substrate 40 carrying the external electronic device 30. The number of films included in the display panel 001 is reduced as much as possible, so that the display panel 001 and the display device including the display panel 001 are light and thin, and good man-machine interaction performance is achieved.
In an embodiment of the present application, please refer to fig. 4 and fig. 5, in which fig. 4 is a schematic diagram of a display panel according to another embodiment of the present application, and fig. 5 is a cross-sectional view of the display panel along the BB' direction according to another embodiment of the present application. As shown in fig. 4 and 5, the display panel 001 further includes foam 60. Specifically, the foam 60 is disposed on the protection layer 10 and located on a side of the protection layer 10 away from the light emitting surface of the display panel 10. More specifically, the external electronic device 30 is disposed between the foam 60 and the conductive film 20. That is, the foam 60 is provided between the external electronic device 30 and the protective layer 10. The foam 60 can effectively buffer the display panel 001 and can shield the influence of external light on the display effect of the display panel 001. The external electronic device 30 is arranged on the foam 60, so that the external electronic device 30 can be effectively buffered, and the external electronic device 30 is prevented from being damaged when being impacted.
When the protective layer 10 has conductivity only in a partial region, the entire surface of the conductive film 20 may be covered with the protective layer 10, or the conductive film 20 may be provided only at a position corresponding to the partial region where the protective layer 10 has conductivity. Referring to fig. 1, 3, 4 and 5, for example, the protection layer 10 may include a first conductive portion 10a and an insulating portion 10 b. Correspondingly, the conductive film 20 may be disposed only at a position corresponding to the first conductive portion 10a to form a cavity with the first conductive portion 10a of the protective layer 10 to accommodate the external electronic device 30.
It should be further noted that, when the display panel 001 includes foam and only a partial region of the protection layer 10 of the display panel 001 has conductivity, the foam 60 may be disposed only in the conductive region (e.g., the first conductive portion 10a) of the protection layer 10, or may be disposed on the whole surface.
As shown in fig. 4 and 5, the foam 60 is disposed on the whole surface, which means that the foam 60, i.e., the conductive region (e.g., the first conductive portion 10a) located on the protective layer 10, is also located on the insulating portion 10b of the protective layer 10. At this time, with continued reference to fig. 4, the foam 60 may include a first portion 60a of the first conductive portion 10a disposed in the protective layer 10 and also include a second portion 60b disposed in the insulating region 10 b. Specifically, the first portion 60a of the foam 60 is disposed in the cavity formed by the first conductive portion 10a of the protective layer 10 and the conductive film 20, the second portion 60b of the foam 60 is disposed outside the cavity, and the first portion 60a is disposed apart from the second portion 60 b. When the foam 60 includes the first portion 60a and the second portion 60b, the first portion 60a and the second portion 60b may also be disposed in connection, and in this case, the conductive film 20 further includes an opening facing the second portion 60b, so as to connect the first portion 60a and the second portion 60b disposed in the cavity.
In an embodiment of the present application, please refer to fig. 6 to 9, fig. 6 is a schematic diagram of a display panel according to still another embodiment of the present application, fig. 7 is a cross-sectional view of the display panel according to still another embodiment of the present application along the direction BB ', fig. 8 is a schematic diagram of a display panel according to still another embodiment of the present application, and fig. 9 is a cross-sectional view of the display panel according to still another embodiment of the present application along the direction BB'. The protective layer 10 of the display panel 001 is a whole surface conductive structure. Optionally, the protective layer 10 comprises ink, and the ink layer is fully doped with conductive particles. The conductive particles doped in the protection layer 10 can make the protection layer 10 opaque, and can effectively avoid the influence of external light on the display effect in the display panel 001. Meanwhile, the conductive particles are doped in the protective layer 10, so that the protective layer 10 has conductivity, and the influence of an external electromagnetic signal on a signal in the display panel 001 can be effectively avoided, and meanwhile, the influence of the signal in the display panel 001 on an electronic device arranged on the backlight side of the display panel 001 is avoided.
When the protective layer 10 of the display panel 001 is a whole-surface conductive structure, the conductive film 20 may be disposed only in a partial region of the protective layer 10, as long as the conductive film 20 and the protective layer 10 can form a cavity capable of accommodating the external electronic device 30.
When the protective layer 10 of the display panel 001 has a full-surface conductive structure, the conductive film 20 may cover the entire surface of the protective layer 10. That is, the conductive film 20 may cover the protection layer 10 in other regions, in addition to forming a cavity with the protection layer 10 for accommodating the external electronic device 30. Therefore, the external electromagnetic interference of the display panel 001 can be effectively shielded.
Please refer to fig. 6 and 7, when the protection layer 10 of the display panel 001 is a full-surface conductive structure and the conductive film 20 covers the full-surface protection layer 10, if the display panel 001 further includes the foam 60, a projection of the foam 60 on the protection layer 10 is covered by the protection layer 10 and surrounded by the first edge 101 of the protection layer 10, so as to ensure that the second edge 201 of the conductive film 20 can contact with the first edge 101 of the protection layer 10, and thus a cavity with an electromagnetic shielding effect can be formed.
It should be further noted that, referring to fig. 8 and 9, when the protection layer 10 of the display panel 001 is a whole-surface conductive structure and the conductive film 20 covers the whole-surface protection layer 10, if the display panel 001 does not include the foam 60, that is, the protection layer 10 is in direct contact with the conductive film 20 except for the position of the electronic device disposed between the protection layer 10 and the conductive film 20. Since the whole surface of the protection layer 10 is doped with the conductive particles, the protection layer 10 has a whole surface shading effect, so that the foam 60 having the shading effect can be replaced, and the thickness of the display panel 001 can be effectively reduced.
In an embodiment of the present application, please refer to fig. 10 and 11, fig. 10 is a schematic diagram of a display panel according to still another embodiment of the present application, and fig. 11 is a cross-sectional view of the display panel according to still another embodiment of the present application along the direction BB'. Wherein the protective layer 10 includes a second conductive portion 10c in addition to the first conductive portion 10 a. Correspondingly, the conductive film 20 includes a first partial conductive film 20a corresponding to the first conductive portion 10a, and a second partial conductive film 20b corresponding to the second conductive portion 10 c. The cavity formed by the first conductive portion 10a and the first conductive film portion 20a can accommodate the external electronic device 30, and the cavity formed by the second conductive portion 10c and the second conductive film portion 20b can accommodate other electronic devices that are easily affected by external electromagnetic waves or easily generate electromagnetic signals affecting the display panel 001.
Optionally, the protection layer 10 may include other insulating portions 10b besides the first conductive portion 10a and the second conductive portion 10c, and of course, the protection layer 10 may include only different conductive portions. The first conductive portion 10a and the second conductive portion 10c may have the same conductivity or different conductivities.
When the conductivities of the first conductive portion 10a and the second conductive portion 10c are the same, the same conductive particles with the same concentration can be doped in the protection layer 10 corresponding to the first conductive portion 10a and the second conductive portion 10c, and the process is simple and easy to implement.
The conductivities of the first conductive portion 10a and the second conductive portion 10b may also be different, and specifically, the conductivities may be achieved by doping different conductive particles at different positions of the protective layer 10 corresponding to the first conductive portion 10a and the second conductive portion 10b, or by doping the same conductive particles with different concentrations. Thus, the conductivity of the first conductive portion 10a and the second conductive portion 10b can be designed according to the degree of the external electronic device 30 and other electronic devices affected by external electromagnetic interference or the degree of the effect on signals in the display panel.
The application further provides a display device, as shown in fig. 12, fig. 12 is a schematic view of the display device provided in an embodiment of the application. The display device is the display panel 001 provided in any of the above embodiments. Specifically, the display panel 001 further includes, in addition to the array substrate 50, a display layer 50 'disposed on the array substrate 50, where the display layer 50' may be a liquid crystal layer or an organic light emitting layer.
Alternatively, the display device may include an antenna 70, and the protective layer 10 includes a first conductive portion 10a and a second conductive portion 10 c. Wherein, the first conductive portion 10a covers the projection of the external electronic device on the protective layer 10, and the external electronic device 30 is disposed in a cavity formed by the first conductive portion 10a and the conductive film 20. Wherein the second conductive portion 10c covers the projection of the antenna 70 on the protective layer 10, and the antenna 70 is disposed in another cavity formed by the second conductive portion 10c and the conductive film 20.
Optionally, the second conductive portion 10c has a different conductivity than the first conductive portion 10a, preferably the second conductive portion 10c has a conductivity greater than the first conductive portion 10 a. Specifically, the first conductive portion 10a and the second conductive portion 10c may both include ink and conductive particles, i.e., the first conductive portion 10a and the second conductive portion 10c may both be doped with conductive particles in the ink. Wherein the concentration of conductive particles of the first conductive portion 10a is less than the concentration of conductive particles of the second conductive portion 10 c. Since the rf of the antenna 70 is relatively strong, the antenna 70 is disposed in the cavity formed by the second conductive portion 10c and the conductive film 20, so as to effectively avoid the influence of the antenna 70 on the signal in the display panel 001, and also effectively avoid the signal interference of the antenna 70 on the electronic device disposed on the backlight surface of the display panel 001.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
