Fig. 1 is one of schematic cross-sectional views of a display panel shown in an exemplary embodiment. As shown in fig. 1, the present disclosure provides a display panel 100, where the display panel 100 may include a display layer 1, a protective layer 2, and a support layer 3, the display layer 1 is disposed on the protective layer 2 and the support layer 3, the protective layer 2 may be disposed closer to an outside of the display panel 100 than the display layer 1, and the protective layer 2 may include a cover glass or a thin film layer, and the cover glass may resist an impact force from a front surface of the display panel 100 and protect the display panel 100 from dust. The supporting layer 3 can be connected with the display layer 1, and the supporting layer 3 can include a piezoelectric thin film layer, when electrifying the piezoelectric thin film layer, the piezoelectric thin film layer can deform, so as to drive the display layer 1 and the protective layer 2 to vibrate, thereby realizing the vibration and sound production of the display panel 100, and simultaneously, when a user touches or presses the display panel 100, the piezoelectric thin film layer can be electrified, so as to drive the display layer 1 and the protective layer 2 to vibrate, thereby performing the tactile feedback on the touch or pressing operation performed by the user. The display panel 100 may include an organic light emitting display panel or a liquid crystal display panel, which is not limited by the present disclosure.
Further, still as shown in fig. 1, the display panel 100 may further include an electrostatic protection layer 4, the electrostatic protection layer 4 may be connected to the support layer 3, and the support layer 3 is disposed between the display layer 1 and the electrostatic protection layer 4, so that during the process of energizing the piezoelectric thin film layer, the purpose of electrostatic protection may be performed by the electrostatic protection layer 4. The static electricity shield layer 4 may include a copper foil layer, and, as also shown in fig. 1, the static electricity shield layer 4 may include a ventilation hole 41 through which the piezoelectric thin film layer, the display layer, and the like can be radiated.
It can be known from the above embodiments that, in the display panel 100 of the present disclosure, the display layer 1 may be supported by the connection between the support layer 3 and the display layer 1, which is beneficial to improving the overall impact resistance of the display panel 100, and since the support layer 3 may include the piezoelectric thin film layer, the vibration of the display panel 100 may be realized through the piezoelectric thin film layer, so as to achieve the purpose of vibration sound production and tactile feedback.
Currently, in order to buffer the impact force from the back of the display panel, a buffer foam is usually disposed on the back of the display panel away from the display side of the display panel, but the buffer foam is weak in impact resistance and is easily deformed when being subjected to an external impact, so that the display panel is deformed accordingly. Generally speaking, when the impact force of the back is greater than 10N, the impact force acts on the display layer of the display panel through the buffer foam, which easily causes the front surface of the display panel to have pits; when the back impact force is larger than 300N, the impact force acts on the display layer of the display panel through the buffering foam, so that the display panel is easy to have a dead pixel, and the display effect is poor. In one embodiment, as shown in fig. 1 and 2, therefore, the support layer 3 may comprise only piezoelectric film layers, that is, the piezoelectric film layer can be directly or indirectly connected to the display layer 2, and as can be seen from the pressure-deformation variation curve of the buffer foam and the piezoelectric film layer in fig. 3, the piezoelectric film layer has higher hardness, and under the same pressure, the deformation of the piezoelectric film layer is smaller than that of the buffer foam, therefore, compared with the technical scheme of supporting by using the buffer foam in the related art, the display layer 1 is supported by the piezoelectric film layer in the present disclosure, so that while the vibration sound production and the tactile feedback functions of the display panel 100 are realized, the impact resistance of the display panel 100 is improved, the risk of breakage of the display panel 100 under the external impact force is reduced, meanwhile, the area of the piezoelectric film layer is increased, so that the area of the display panel 100 capable of tactile feedback is increased.
In another embodiment, as shown in fig. 4 and 5, the support layer 3 may include a piezoelectric thin film layer 31 and a buffer layer 32, and at least one of the buffer layer 32 and the piezoelectric thin film layer 31 may be connected to the display layer 1. The buffer layer 32 can comprise foam, so that the buffer layer 32 and the piezoelectric film layer 31 can jointly realize a supporting effect, the vibration sound production and the touch feedback function of the display panel 100 are realized, meanwhile, the material consumption of the piezoelectric film layer 31 is reduced, and the cost is reduced. The buffer layer 32 and the piezoelectric thin film layer 31 may be disposed adjacent to each other as shown in fig. 4, or as shown in fig. 5, the buffer layer 32 is disposed around the piezoelectric thin film layer 31, or in other embodiments, the piezoelectric thin film layer 31 is disposed around the buffer layer 32, or the buffer layer 32 is disposed around a part of the piezoelectric thin film layer 31, or the piezoelectric thin film layer 31 is disposed around a part of the buffer layer 32, which is not limited in this disclosure.
In one embodiment, as shown in fig. 6 and 7, the piezoelectric thin film layer 31 and the buffer layer 32 of the support layer 3 are both connected to the display layer 1, i.e. the buffer layer 32 may be arranged side by side with the piezoelectric thin film layer 31, and the thicknesses of the two may be substantially the same, so that both may be connected to the display layer 1 and the electrostatic protection layer 4. The embodiment of fig. 7 is relative to the embodiment of fig. 6, in which the area of the piezoelectric thin film layer 31 is larger, so that the area of the tactile feedback on the display panel 100 is larger, and the sound pressure level of the display panel 100 is higher.
In another embodiment, as shown in fig. 8, the buffer layer 32 may be disposed around the piezoelectric thin film layer 31, and the buffer layer 32 is connected to the display layer 1 and the electrostatic protection layer 4, respectively, while the piezoelectric thin film layer 31 is connected to the electrostatic protection layer 4, and the piezoelectric thin film layer 31 may be spaced from the display layer 1 by a set distance. When the piezoelectric thin film layer 31 vibrates, the vibration can be transmitted to the electrostatic protection layer 4 and the buffer layer 32, and then transmitted to the display layer 1 and the protection layer 2 through the buffer layer 32, and because the structure of the electrostatic protection layer 4 driving the display layer 1 and the protection layer 2 is lighter, the thrust for pushing the electrostatic protection layer 4 to vibrate is smaller than the thrust for pushing the display layer 1 and the protection layer 2. Further, when the piezoelectric thin film layer 31 is connected to each position of the region surrounded by the buffer layer 32 on the electrostatic protection layer 4, a sound cavity can be formed by surrounding the piezoelectric thin film layer 31, the buffer layer 32 and the display layer 1, so as to improve the sound production effect of the display panel 100. Alternatively, in another embodiment, if the piezoelectric thin film layer 31 is not attached to a part of the region surrounded by the buffer layer 32 on the electrostatic protection layer 4, the sound cavity may be surrounded by the piezoelectric thin film layer 31, the buffer layer 32, the display layer 1, and the electrostatic protection layer 4.
In still another embodiment, as shown in fig. 9, the buffer layer 32 may be disposed around the piezoelectric thin film layer 31, and the buffer layer 32 is connected to the display layer 1 and the electrostatic protection layer 4, respectively, while the piezoelectric thin film layer 31 is connected to the display layer 1, and the piezoelectric thin film layer 31 and the electrostatic protection layer 4 may be spaced apart by a set distance. Thus, when the piezoelectric thin film layer 31 vibrates, since the piezoelectric thin film layer 31 is directly connected to the display layer 1, the vibration can be directly transmitted to the display layer 1, and compared with the technical scheme of fig. 8, the transmission process of the vibration can be shortened, and the loss can be reduced. Moreover, when the piezoelectric thin film layer 31 is connected to each position of the area surrounded by the buffer layer 32 on the display layer 1, a sound cavity can be formed by surrounding the piezoelectric thin film layer 31, the buffer layer 32 and the electrostatic protection layer 4, so as to improve the sound production effect of the display panel 100. Alternatively, in another embodiment, if the piezoelectric thin film layer 31 is not attached to a part of the region surrounded by the buffer layer 32 on the display layer 1, the sound cavity may be surrounded by the piezoelectric thin film layer 31, the buffer layer 32, the display layer 1, and the electrostatic protection layer 4.
In the above embodiments, a first heat dissipation layer (not shown) may be further disposed in the display panel 100, and the first heat dissipation layer may be disposed between the support layer 3 and the electrostatic protection layer 4, specifically, between the buffer layer 32 and the electrostatic protection layer 4, or between the piezoelectric thin film layer 31 and the electrostatic protection layer 4, or both between the buffer layer 32 and the electrostatic protection layer 4 and between the piezoelectric thin film layer 31 and the electrostatic protection layer 4, which is not limited by the disclosure.
Similarly, a second heat dissipation layer (not shown) may be disposed between the support layer 3 and the display layer 1, and the second heat dissipation layer may be disposed between the buffer layer 32 and the display layer 1, or may be disposed between the piezoelectric thin film layer 31 and the display layer 1, or may be disposed between the buffer layer 32 and the display layer 1 and between the piezoelectric thin film layer 31 and the display layer 1. And in particular may be designed as desired, and the present disclosure is not intended to be limited thereto. Wherein the first and second heat dissipation layers may include graphite layers.
