[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] An embodiment of the present application provides a display panel, including an array substrate, a color filter substrate and a liquid crystal layer. The color filter substrate and the array substrate are arranged opposite to each other, and the liquid crystal layer is arranged between the array substrate and the color filter substrate. The display panel also includes a vibration feedback layer, which is built into the array substrate or the color filter substrate. The vibration feedback layer is used to respond to the control of the touch operation electrical signal of the display panel to generate mechanical vibration, so that the area of the display panel corresponding to the touch operation vibrates.

[0042] In an embodiment of the present application, a vibration feedback layer is built into the array substrate or color film substrate of the display panel, and the vibration feedback layer generates mechanical vibration in response to the touch operation of the display panel, so that the area of the display panel corresponding to the touch operation vibrates, so that the corresponding area can also generate a vibration tactile sensation when the display panel is touched.

[0043] See also Figure 1 , Figure 1 A schematic diagram of the film layer structure of a display panel provided in an embodiment of the present application is provided. The display panel 100 includes an array substrate 1, a color filter substrate 2 and a liquid crystal layer 3. The array substrate 1 and the color filter substrate 2 are arranged opposite to each other, and the liquid crystal layer 3 is arranged between the array substrate 1 and the color filter substrate 2.

[0044] like Figure 1 As shown, the display panel 100 also includes a vibration feedback layer 4, which is built into the array substrate 1 or the color film substrate 2. The vibration feedback layer 4 is used to generate mechanical vibration in response to the touch operation of the display panel, so that the area of the display panel corresponding to the touch operation vibrates.

[0045] In some embodiments, see Figure 1 The vibration feedback layer 4 includes a first electrode layer 41, an electrodeformable layer 42, and a second electrode layer 43. The electrodeformable layer 42 is disposed on one side of the first electrode layer 41, and the second electrode layer 43 is disposed on a side of the electrodeformable layer 42 away from the first electrode layer 41. The first and second electrode layers 41, 43 control the electrodeformable layer to mechanically deform in response to electrical signals corresponding to touch operations. The first and second electrode layers 41, 43 receive different electrical signals and form alternating electric fields. Under the control of the alternating electric fields, the electrodeformable layer 42 continuously mechanically deforms and returns to its original state, causing the vibration feedback layer 4 to mechanically vibrate, thereby vibrating the area of the display panel corresponding to the touch operation.

[0046] In some embodiments, the material of the electrodeformable layer 42 includes any one of aluminum nitride, lead zirconate titanate, and polyvinylidene fluoride.

[0047] In some embodiments, the first electrode layer 41 and the second electrode layer 43 include a transparent conductive material, which may be indium tin oxide. Selecting a transparent conductive material as the material for the first electrode layer 41 and the second electrode layer 43 can reduce the effect of the first electrode layer 41 and the second electrode layer 43 on the light transmittance of the display panel.

[0048] In some embodiments, the first electrode layer 41 includes multiple columns of first sub-electrodes arranged in a row-wise direction. The second electrode layer 43 includes multiple rows of second sub-electrodes arranged in a column-wise direction. The first and second sub-electrodes are interdigitated. The electrodeformable layer 42 is located at the intersection of the first and second sub-electrodes and between them. The intersection of the first and second sub-electrodes can be considered a vibration feedback point. The multiple columns of first sub-electrodes and the multiple rows of second sub-electrodes intersect to form a plurality of vibration feedback points arranged in an array. A touch operation on the display panel can determine the touch point location. Based on the touch point location, the first and second sub-electrodes corresponding to the touch point location can be determined. By applying different electrical signals to the corresponding first and second sub-electrodes, an alternating electric field is generated at the touch point location, controlling the electrodeformable layer 42 at the touch point location to produce mechanical deformation, thereby causing the area of the display panel corresponding to the touch point location to vibrate. Therefore, the display panel provided by the embodiments of the present application can achieve a vibration tactile sensation at any touch point location.

[0049] In some embodiments, as Figure 1 As shown, the display panel 100 includes a display area AA, which includes a plurality of light-transmitting areas AA1 and non-light-transmitting areas AA2 arranged between adjacent light-transmitting areas AA1. The area where each light-transmitting area AA1 is located can be regarded as a sub-pixel. Adjacent light-transmitting areas AA1 are separated by the non-light-transmitting areas AA2 to prevent color mixing between adjacent sub-pixels, thereby improving the contrast of the display panel.

[0050] In some embodiments, as Figure 1 and Figure 2 As shown, Figure 2 This is a top view of the electrodeformable layer provided in an embodiment of the present application. The electrodeformable layer 42 has a plurality of openings 421 corresponding to the light-transmitting area AA1. The openings 421 corresponding to the light-transmitting area AA1 means that the openings 421 are at least partially located in the light-transmitting area AA1.

[0051] In some embodiments, the area of the opening 421 is greater than or equal to the area of the light-transmitting area AA1. For example, when the area of the opening 421 is equal to the area of the light-transmitting area AA1, each opening 421 corresponds to a light-transmitting area AA1. When the area of the opening 421 is greater than the area of the light-transmitting area AA1, the same opening 421 may have one, or two or more light-transmitting areas AA1. By forming multiple openings 421 in the electrodeformable layer 42 to form a grid-like structure, light emitted by the backlight module can be emitted through the openings 421 in the electrodeformable layer 42. This avoids affecting the aperture ratio of the display panel due to the addition of the electrodeformable layer 42.

[0052] In some embodiments, the color filter substrate 2 includes a light shielding layer 21 , which is located in the non-light-transmitting area AA2 , and an orthographic projection of the light shielding layer 21 on the array substrate 1 overlaps with an orthographic projection of the electrodeformable layer 42 on the array substrate 1 .

[0053] like Figure 1 As shown, the light-shielding layer 21 has multiple light-shielding portions 211, which are located in the non-light-transmitting area AA2. The color filter substrate 2 also includes multiple color resists 23, with the light-shielding portions 211 disposed between adjacent color resists 23. The light-shielding portions 211 are used to separate adjacent color resists 23 to prevent color mixing between adjacent sub-pixels. The electrodeformable layer 42 includes multiple electrodeformable portions, which are interconnected to form a grid structure. The orthographic projections of the light-shielding portions 211 on the array substrate 1 overlap the orthographic projections of the electrodeformable portions on the array substrate 1. By disposing the electrodeformable layer 42 in the non-light-transmitting area AA2 and overlapping it with the light-shielding layer 21, the area where the light-shielding layer 21 is located is utilized to place the electrodeformable layer 42, thereby avoiding affecting the aperture ratio of the display panel.

[0054] In some embodiments, as Figure 1 As shown, the vibration feedback layer 4 is built into the array substrate 1. Specifically, the array substrate 1 includes a second substrate 11 and a driving circuit layer 12. The driving circuit layer 12 is arranged on a side of the second substrate 11 close to the color filter substrate 2, and the vibration feedback layer 4 is arranged between the second substrate 11 and the driving circuit layer 12.

[0055] In some embodiments, as Figure 1 As shown, the first electrode layer 41 is arranged on the second substrate 11, the electrodeformable layer 42 is arranged on the surface of the first electrode layer 41 away from the second substrate 11, the second electrode layer 43 is arranged on the surface of the electrodeformable layer 42 away from the first electrode layer 41, and the driving circuit layer 12 is arranged on the side of the second electrode layer 43 away from the second substrate 11.

[0056] In some embodiments, as Figure 1The driving circuit layer 12 includes a gate layer 121, a gate insulating layer 122, an active layer 123, a source-drain layer 124, a planar layer 125, a pixel electrode layer 126, and a first alignment layer 127, which are sequentially stacked on the side of the second electrode layer 43 away from the electrodeformable layer 42. The gate layer 121 includes a patterned gate, and the orthographic projection of the gate on the second substrate 11 overlaps with the orthographic projection of the electrodeformable layer 42 on the second substrate 11.

[0057] In some embodiments, the vibration feedback layer 4 further includes at least one buffer layer 44, which is disposed on a side of the first electrode layer 41 or the second electrode layer 43 away from the electrodeformable layer 42. The dielectric constant of the buffer layer 44 is smaller than the dielectric constant of the insulating layer in the array substrate 1 or the color filter substrate 2, and the elastic modulus of the buffer layer 44 is smaller than the elastic modulus of the electrodeformable layer 42.

[0058] In some embodiments, as Figure 1 As shown, the vibration feedback layer 4 includes a buffer layer 44, which is arranged on the surface of the second electrode layer 43 away from the electrodeformable layer 42. The buffer layer 44 also covers the electrodeformable layer 42 and the first electrode layer 41. The gate layer 121 is arranged on the surface of the buffer layer 44 away from the second electrode layer 43.

[0059] In some embodiments, the dielectric constant of the buffer layer 44 is greater than the dielectric constant of the gate insulating layer 122 and the flat layer 125. In this way, the buffer layer 44 can be used to isolate the alternating electric field formed between the driving circuit layer 12 and the first electrode layer 41 and the second electrode layer 43, thereby reducing the coupling capacitance between the first electrode layer 41 or the second electrode layer 43 and the gate layer 121 or the source and drain layer 124. At the same time, it can also prevent the alternating electric field formed by the first electrode layer 41 and the second electrode layer 43 from affecting the orientation of liquid crystal molecules in the liquid crystal layer 3, thereby ensuring that the display effect of the display panel is not affected while realizing the function of vibration touch feedback.

[0060] In some embodiments, the elastic modulus of the buffer layer 44 is less than that of the electrodeformable layer 42. It should be noted that if the elastic modulus of the buffer layer 44 is too large, it means that the buffer layer 44 is too rigid, causing the vibration energy generated by the electrodeformable layer 42 to be absorbed or reflected by the buffer layer 44, reducing the vibration intensity transmitted to the display panel surface and resulting in reduced sensitivity of vibration feedback. In addition, since the rapid deformation of the electrodeformable layer 42 can cause local stress concentration at the interface between the electrodeformable layer 42 and the adjacent film layer, if the buffer layer 44 is too rigid, the stress concentration at the interface between the buffer layer 44 and the electrodeformable layer 42 or the second electrode layer 43 can cause the film layer to delaminate. In this embodiment, the elastic modulus of the buffer layer 44 is smaller than that of the electrodeformable layer 42. As a flexible medium, the buffer layer 44 can not only reduce energy loss during vibration transmission and prevent the buffer layer 44 from being too rigid and hindering the deformation freedom of the electrodeformable layer 42, but also absorb and disperse local stress, reduce the risk of delamination between the buffer layer 44 and the adjacent film layer, and protect the liquid crystal layer from mechanical shock.

[0061] In some embodiments, the dielectric constant of the buffer layer 44 is less than 50% of the dielectric constant of the insulating layer in the array substrate or the color filter substrate, and the elastic modulus of the buffer layer 44 is less than 10% of the elastic modulus of the electrodeformable layer 42. In this way, the buffer layer 44 can both transmit mechanical vibrations and absorb stress differences between the electrodeformable layer 42 and other adjacent film layers, thereby avoiding structural damage to the display panel.

[0062] In some embodiments, the dielectric constant of the buffer layer 44 is greater than or equal to 1.5 and less than or equal to 2.8. For example, the dielectric constant of the buffer layer 44 can be 1.5, 1.8, 2, 2.3, 2.5 or 2.8, etc. In this way, the buffer layer 44 can have a lower dielectric constant, thereby utilizing the buffer layer 44 to isolate the alternating electric field formed between the driving circuit layer 12 and the first electrode layer 41 and the second electrode layer 43, thereby reducing the coupling capacitance between the first electrode layer 41 or the second electrode layer 43 and the gate layer 121 or the source and drain layer 124, and at the same time, preventing the alternating electric field formed by the first electrode layer 41 and the second electrode layer 43 from affecting the orientation of the liquid crystal molecules in the liquid crystal layer 3, thereby ensuring that the display effect of the display panel is not affected while achieving the function of vibration touch feedback.

[0063] In some embodiments, the material of the buffer layer 44 may be polytetrafluoroethylene.

[0064] In some embodiments, as Figure 1As shown, the display panel 100 also includes a plurality of spacers 5, which are arranged between the array substrate 1 and the color film substrate 2. The spacers 5 are used to maintain the thickness of the liquid crystal box between the array substrate 1 and the color film substrate 2 to prevent the liquid crystal layer of the display panel from being squeezed and deformed when subjected to external force, resulting in poor display.

[0065] In some embodiments, as Figure 3 As shown, Figure 3 This is a schematic diagram of the film structure of another display panel provided in an embodiment of the present application, and its structure is similar to Figure 1 The structures of the display panels shown are substantially the same, with the difference being that the vibration feedback layer 4 is built into the color filter substrate 2 .

[0066] like Figure 3 As shown, the color filter substrate 2 includes a first substrate 22, a light shielding layer 21, a color resist 23, a common electrode layer 24, and a second alignment layer 25. The light shielding layer 21 is disposed on one side of the first substrate 22, and the color resist 23 is disposed on one side of the first substrate 22. The light shielding layer 21 is located between adjacent color resists 23. The common electrode layer 24 is disposed on the side of the color resist 23 and the light shielding layer 21 away from the first substrate 22, and the second alignment layer 25 is disposed on the side of the common electrode layer 24 away from the first substrate 22.

[0067] In some embodiments, the vibration feedback layer 4 is disposed between the light shielding layer 21 and the first substrate 22 .

[0068] like Figure 3 As shown, the first electrode layer 41 is disposed on the surface of the first substrate 22 close to the array substrate 1, the electrodeformable layer 42 is disposed on the side of the first electrode layer 41 away from the first substrate 22, the second electrode layer 43 is disposed on the side of the electrodeformable layer 42 away from the first electrode layer 41, and the light shielding layer 21 is disposed on the side of the second electrode layer 43 away from the electrodeformable layer 42. The electrodeformable layer 42, the second electrode layer 43, and the light shielding layer 21 are all disposed between adjacent color resists 23. By placing the vibration feedback layer 4 in the area of the color filter substrate 2 where the light shielding layer 21 is located, it is possible to avoid affecting the aperture ratio of the display panel.

[0069] In some embodiments, as Figure 3 As shown, the thickness of the electrodeformable layer 42 is smaller than the thickness of the color resist 23 .

[0070] In some embodiments, the thickness of the electrodeformable layer 42 is greater than or equal to 1 micron and less than or equal to 10 microns. For example, the thickness of the electrodeformable layer 42 can be 1 micron, 3 microns, 5 microns, 7 microns, 9 microns, or 10 microns. It should be noted that if the thickness of the electrodeformable layer 42 is too great, not only will the overall thickness of the display panel increase, but it will also cause the electrodeformable layer 42 to deform significantly, increasing the risk of delamination at the interface between the electrodeformable layer 42 and adjacent film layers. If the thickness of the electrodeformable layer 42 is too small, the deformation of the electrodeformable layer 42 will be small, resulting in less noticeable vibration feedback from the display panel.

[0071] In some embodiments, the voltage connected to the vibration feedback layer 4 is greater than or equal to 0 and less than or equal to 36V. It should be noted that if the voltage connected to the vibration feedback layer 4 is too large, the electric field strength inside the electrodeformable layer 42 will be relatively large, which will not only accelerate the aging of the electrodeformable material, but also cause the polarization of the electrodeformable material to saturate, resulting in nonlinear distortion of the electrodeformable material, and causing the problem of reduced driving accuracy of the vibration feedback layer 4. When the electric field strength inside the electrodeformable layer 42 exceeds the breakdown field strength of the material, the electrodeformable layer 42 will be broken down, causing the electrodeformable performance of the electrodeformable layer 42 to fail and the vibration feedback effect to be unable to be achieved. In this embodiment, by limiting the voltage connected to the vibration feedback layer 4 to between 0 and 36V, the electrodeformable material in the electrodeformable layer 42 can be prevented from being broken down, and the service life of the electrodeformable material can be extended, thereby improving the driving accuracy and stability of the vibration feedback layer 4.

[0072] In some embodiments, as Figure 3 As shown, the array substrate 1 further includes a passivation layer 13 , which is disposed between the second substrate 11 and the driving circuit layer 12 . The material of the passivation layer 13 includes at least one of silicon nitride, silicon oxide, or silicon oxynitride.

[0073] According to the display panel provided in the above embodiment of the present application, the embodiment of the present application further provides a display device, see Figure 4 , Figure 4The structural diagram of the display device provided in the embodiment of the present application, the display device 1000 includes a display panel 100, a touch layer 200 and a control module. The display panel 100 can be the display panel provided by any of the above embodiments, and the touch layer 200 is arranged on the light-emitting side of the display panel 100. The control module can be a touch driver chip. The control module can be directly bound to the array substrate, or can be bound to a flexible circuit board or a printed circuit board. The control module is electrically connected to the touch layer 200 and the vibration feedback layer 4 in the display panel 100 respectively. The touch layer 200 is used to collect touch signals and feed back the collected touch signals to the control module. The control module is used to determine the touch point position based on the touch signal fed back by the touch layer 200, generate a corresponding touch feedback signal based on the touch point position, and apply the touch feedback signal to the vibration feedback layer 4 at the position corresponding to the touch point position. The vibration feedback layer 4 is used to generate mechanical vibration in response to the control of the touch feedback signal.

[0074] In some embodiments, as Figure 4 As shown, the display device 1000 further includes a backlight module 300 , which is disposed on the light incident side of the display panel 100 .

By integrating the vibration feedback layer into the array substrate or the color filter substrate of the display panel, and making the vibration feedback layer generate mechanical vibration in response to the touch operation of the display panel, so that the area of the display panel corresponding to the touch operation vibrates, the corresponding area can also generate a vibration tactile sensation when the display panel is touched.
