Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] Today, all display manufacturers are striving to provide thinner and lighter displays with higher screen-to-body ratios. This is driving display panel suppliers to integrate more sensors on the screen to save space and increase the screen-to-body ratio. Currently, it is known that screens can integrate ambient light color temperature sensors, ambient light brightness sensors, fingerprint sensors, and pressure sensors.

[0003] However, the existing screen-integrated pressure sensor structure usually adds two layers of parallel conductors facing each other to form a capacitor in the screen. When pressed, the distance between the parallel conductors changes, and the size of the capacitor will also change accordingly. By detecting the change in the capacitance of the capacitor, the pressure intensity of the pressing action or the degree of deformation of the screen can be determined. However, the existing screen-integrated pressure sensor is limited by the maximum deformation of the screen. The degree of strain of the screen after being subjected to force will gradually decrease. That is, when pressed, the distance between the parallel conductors changes, and the deformation of the screen will gradually decrease as the pressure increases. This will reduce the change gradient of the strain capacitance caused by the deformation of the screen, resulting in insufficient linearity and pressure gradient of the integrated pressure sensor of the screen, thereby limiting the application scenarios of the screen-integrated pressure sensor. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present application provides a display panel and a display device that can improve the pressure sensing gradient of the pressure sensor integrated in the display panel, thereby improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel.

[0010] A first electrode is disposed in the first spacer;

[0011] a second electrode disposed on a side of the second substrate facing the first substrate, the first electrode and the second electrode being opposite to each other and spaced apart along the first direction to form a first capacitor;

[0012] An elastomer is arranged between the first spacer and the second substrate, and the peripheral side wall of the first spacer forms a second capacitor with the liquid crystal in the liquid crystal layer, and the second capacitor is an electric double layer capacitor; the elastomer is configured to change the area of the peripheral side wall of the first spacer covered by the elastomer under the action of the first spacer to change the size of the second capacitor.

[0013] In a possible embodiment, the auxiliary spacer also includes a second spacer, which is arranged on the side of the second substrate facing the first substrate, and the second spacer is located in the liquid crystal layer and covers the second electrode; the first spacer and the second spacer are opposite to each other and spaced apart along the first direction, and the elastomer is arranged between the first spacer and the second spacer.

[0014] In a possible implementation, along the first direction, the orthographic projection of the first spacer on the elastic body is completely located on the elastic body, and the orthographic projection of the elastic body on the second spacer is completely located on the second spacer.

[0015] In a possible embodiment, the second spacer has a groove on the side facing the first spacer, the elastomer is arranged in the groove, and the end of the first spacer facing the second spacer is located in the groove and abuts against the elastomer; there is a gap between the peripheral side wall of the first spacer and the inner side wall of the groove, and at least part of the liquid crystal in the liquid crystal layer is located in the gap and covers the peripheral side wall of the first spacer.

[0016] In a possible embodiment, the radial dimension of the first spacer gradually increases from one end of the first spacer toward the second spacer to the end of the first spacer away from the second spacer; and / or the radial dimension of the groove gradually increases from the opening of the groove to the bottom of the groove.

[0017] In one possible embodiment, the first electrode extends along the first direction, and the peripheral side walls of the first electrode form a third capacitor with the liquid crystal of the liquid crystal layer; the elastomer is configured to change the area of the positive projection of the peripheral side walls of the elastomer surrounding the first electrode under the action of the first spacer, so as to change the size of the third capacitor.

[0018] In a possible embodiment, the liquid crystal of the liquid crystal layer in contact with the elastomer at the end surface of the first electrode facing the second electrode forms a fourth capacitor, and the magnitude of the fourth capacitor changes with the displacement of the first electrode along the first direction toward the second electrode.

[0019] In a possible embodiment, the display panel further includes a main spacer, which is sandwiched between the first substrate and the second substrate; a black matrix is provided in the first substrate, the main spacer and the black matrix are arranged opposite to each other along the first direction, and the auxiliary spacer and the black matrix are arranged opposite to each other along the first direction.

[0020] In one possible embodiment, the second substrate is provided with a common electrode, which is arranged on the side of the second substrate facing the first substrate, and the common electrode includes the second electrode; or, the second substrate is provided with a pixel electrode, which is arranged on the side of the second substrate facing the first substrate, and the second electrode and the pixel electrode are arranged separately.

[0021] In another aspect, the present application provides a display device, comprising:

[0022] The display panel mentioned above.

[0023] The display panel and display device provided in the present application are sandwiched between a first substrate and a second substrate through a liquid crystal layer and an auxiliary spacer. A first electrode is arranged in the first spacer of the auxiliary spacer, and a second electrode is arranged on the side of the second substrate facing the first substrate, and the second spacer completely covers the second electrode.

[0024] On the one hand, the first electrode and the second electrode are arranged opposite each other and spaced apart along a first direction to form a first capacitor. When the first substrate deforms relative to the second substrate, the first spacer moves with the first substrate, causing the distance between the first electrode and the second electrode 60 to change, thereby causing the first capacitor to change.

[0025] On the other hand, the elastomer is arranged between the first spacer and the second spacer, and the peripheral side walls of the first spacer form a solid-liquid interface with the liquid crystal of the liquid crystal layer. This solid-liquid interface will form a second capacitor, and the second capacitor is an electric double layer capacitor. When the first substrate is deformed relative to the second substrate, the first spacer moves with the first substrate and squeezes the elastomer. Under the action of the first spacer, the elastomer changes the area of the peripheral side walls covering the first spacer, so that the area of the solid-liquid interface formed by the peripheral side walls of the first spacer and the liquid crystal in the liquid crystal layer changes, that is, the area directly facing the liquid crystal in the liquid crystal layer between the peripheral side walls of the first spacer will change, thereby changing the size of the second capacitor. Since the second capacitor is an electric double layer capacitor, its capacitance is extremely large. In the process of changing the area directly facing the liquid crystal in the liquid crystal layer between the peripheral side walls of the first spacer and the liquid crystal, the capacitance of the second capacitor also changes greatly. Therefore, the display panel provided in the first embodiment of the present application is beneficial to improving the pressure sensing gradient of the pressure sensor integrated in the display panel when the first substrate is deformed relative to the second substrate under the same pressure, thereby improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel, facilitating the display panel to achieve more graded settings of pressure sensing, improving the accuracy of the display panel's pressure sensing, and improving the application scenarios of the display panel.

Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] See also Figure 1 , Figure 1 Schematic diagram of the structure of a display device provided in one embodiment of the present application.

[0042] This embodiment provides a display device 1000, comprising a display panel 100, which is configured to display image information. The display device 1000 provided in this embodiment may be used, but is not limited to, mobile phones, tablet computers, laptop computers, desktop computers, in-vehicle equipment, televisions, wearable devices, and the like, although this application does not impose any restrictions thereto. The display panel 100 of the display device 1000 provided in this embodiment also has a pressure sensing function, enabling the display device 1000 to have both image display and pressure sensing functions.

[0043] In some embodiments, the display device 1000 further includes components such as a display panel 100, a driving circuit, and a housing to realize the image display function. The display panel 100 is the core part of the display device 1000 and is responsible for the actual image display. The display device 1000 controls the display content of the display panel 100 through the driving circuit to realize the visual output of information. Through the control of the driving circuit, the display panel 100 can present various images and video content. The housing is a structure used to protect and support the display panel 100 and the driving circuit.

[0044] However, the existing screen-integrated pressure sensor structure usually adds two layers of parallel conductors facing each other to form a capacitor in the screen. When pressed, the distance between the parallel conductors changes, and the size of the capacitor will also change accordingly. By detecting the change in the capacitance of the capacitor, the pressure intensity of the pressing action or the degree of deformation of the screen can be determined. However, the existing screen-integrated pressure sensor is limited by the maximum deformation of the screen. The degree of strain of the screen after being subjected to force will gradually decrease. That is, when pressed, the change in the distance between the parallel conductors will cause the screen deformation to gradually decrease as the pressure increases. This will reduce the change gradient of the strain capacitance generated by the screen deformation, resulting in insufficient linearity and pressure-sensing force gradient of the screen integration, thereby limiting the application scenarios of the screen-integrated pressure sensor. For example, when the screen is applied to in-vehicle physical buttons, the screen's pressure-sensing grading setting will be affected due to the insufficient linearity and pressure-sensing force gradient of the screen, and the inability to provide accurate pressure information input to the vibration feedback device will cause the screen's tactile feedback to be distorted, thereby affecting the accuracy of pressing the in-vehicle screen buttons.

[0045] Based on this, the present application provides a display panel 100 integrated with a pressure sensor to solve the above technical problems. The following is a detailed introduction to the display panel 100 integrated with a pressure sensor provided by the present application.

[0046] First embodiment:

[0047] See also Figures 1 to 5 , Figure 2 This is a cross-sectional structure of a display panel provided in the first embodiment of the present application. Figure 1 , Figure 3 This is a cross-sectional structure of a display panel provided in the first embodiment of the present application. Figure 2 , Figure 4 is a partial schematic diagram of a display panel in a first state provided by the first embodiment of the present application. Figure 5 This is a partial schematic diagram of a display panel in the second state provided by the first embodiment of the present application.

[0048] The first embodiment of the present application provides a display panel 100 for use in the above-mentioned display device 1000. The display panel 100 provided in the first embodiment of the present application includes a first substrate 10, a second substrate 20, a liquid crystal layer 30, an auxiliary spacer 40, a first electrode 50, a second electrode 60, and an elastomer 70.

[0049] The first substrate 10 and the second substrate 20 are opposite to each other and spaced apart along a first direction, and the liquid crystal layer 30 is filled between the first substrate 10 and the second substrate 20. The first direction is the stacking direction of the first substrate 10, the liquid crystal layer 30 and the second substrate 20.

[0050] The auxiliary spacer 40 is located in the liquid crystal layer 30. The auxiliary spacer 40 includes a first spacer 41 and a second spacer 42. The first spacer 41 and the second spacer 42 are both insulators. The first spacer 41 is arranged on the side of the first substrate 10 facing the second substrate 20 and is located in the liquid crystal layer 30. The second spacer 42 is arranged on the side of the second substrate 20 facing the first substrate 10 and is located in the liquid crystal layer 30. The first spacer 41 and the second spacer 42 are opposite to each other and spaced apart along the first direction.

[0051] The first electrode 50 is disposed in the first spacer 41. The second electrode 60 is disposed on the side of the second substrate 20 facing the first substrate 10. The second electrode 60 is completely sandwiched between the second spacer 42 and the second substrate 20, that is, the second spacer 42 completely covers the second electrode 60. The first electrode 50 and the second electrode 60 are opposite and spaced apart along the first direction, so that a first capacitor C is formed between the first electrode 50 and the second electrode 60. 11 .

[0052] The elastic body 70 is disposed between the first spacer 41 and the second spacer 42. The peripheral sidewall of the first spacer 41 forms a solid-liquid interface with the liquid crystal in the liquid crystal layer 30. The solid-liquid interface forms a second capacitor C 21 , the second capacitor C 21 The elastic body 70 is configured to change the area of the sidewall of the elastic body 70 covering the first spacer 41 under the action of the first spacer 41, thereby changing the area of the solid-liquid interface formed by the sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30, thereby changing the second capacitor C 21 size.

[0053] It's important to understand that the extremely high capacitance of the aforementioned electrical double-layer capacitor (EDLC) is based on the interfacial double-layer theory proposed by physicist Helmholtz. When the electrode is charged, the surface charge attracts opposite ions from the surrounding electrolyte solution, forming a double charge layer. The extremely small distance between these two charge layers, coupled with the unique electrode structure, increases the electrode surface area ten thousandfold, resulting in extremely high capacitance.

[0054] In the first embodiment of the present application, the first substrate 10 is a color filter substrate. Other functional film layers related to color filter substrates are integrated into the first substrate 10. These include, but are not limited to, a pixel layer 11, a panel layer 12, a substrate layer 13, a black matrix 14, and the like. The second substrate 20 is an array substrate. Other functional film layers related to array substrates are integrated into the second substrate 20. These include, but are not limited to, an insulating layer 21, a planar layer 22, a gate 23, a source / drain electrode 24, a pixel electrode 25, a common electrode 26, and the like. It is understood that in other embodiments, the first substrate 10 may be an array substrate, and the second substrate 20 may be a color filter substrate. This is not a limitation of the present application.

[0055] In the first embodiment of the present application, the elastomer 70 is a gas capsule, and the elastomer 70 has the ability to deform when subjected to external force and to restore the deformation when the external force is removed. When the display panel 100 is deformed by external force, the external force is transmitted to the first spacer 41, and the first spacer 41 squeezes the elastomer 70 so that the elastomer 70 is deformed and wrapped around the peripheral side wall of the first spacer 41. When the external force acting on the display panel 100 is removed, the first spacer 41 moves in a direction away from the elastomer 70 under the action of the display panel 100, that is, the external force acting on the elastomer 70 is removed, and the elastomer 70 can restore the deformation. It can be understood that in some other embodiments, the elastomer 70 can be a structure such as elastic silicone, which only needs to meet the functions of the above-mentioned elastomer 70, and the present application does not limit this.

[0056] The display panel 100 provided in the first embodiment of the present application is sandwiched between the first substrate 10 and the second substrate 20 through the liquid crystal layer 30 and the auxiliary spacer 40. The first electrode 50 is arranged in the first spacer 41 of the auxiliary spacer 40, and the second electrode 60 is arranged on the side of the second substrate 20 facing the first substrate 10, and the second spacer 42 completely covers the second electrode 60.

[0057] On the one hand, the first electrode 50 and the second electrode 60 are arranged opposite to each other and spaced apart along a first direction to form a first capacitor C 11 When the first substrate 10 is deformed relative to the second substrate 20, the first spacer 41 moves along with the first substrate 10, causing the distance between the first electrode 50 and the second electrode 60 to change, thereby causing the first capacitor C 11 Changes have occurred.

[0058] On the other hand, the elastic body 70 is disposed between the first spacer 41 and the second spacer 42. The peripheral sidewall of the first spacer 41 forms a solid-liquid interface with the liquid crystal of the liquid crystal layer 30. The solid-liquid interface forms a second capacitor C 21 , and the second capacitor C 21The first spacer 41 moves along with the first substrate 10 and squeezes the elastic body 70. Under the action of the first spacer 41, the elastic body 70 changes the area of the sidewalls covering the first spacer 41, so that the area of the solid-liquid interface formed by the sidewalls of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes. That is, the area facing each other between the sidewalls of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes, thereby changing the second capacitance C. 21 Since the second capacitor C 21 The second capacitor C is an electric double layer capacitor with a very large capacitance. When the facing area between the side wall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes, the second capacitor C 21 The change in capacitance is also extremely large. Therefore, the display panel 100 provided in the first embodiment of the present application, under the same pressure, when the first substrate 10 is deformed relative to the second substrate 20, is conducive to improving the pressure sensing gradient of the pressure sensor integrated in the display panel 100, thereby improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel 100, facilitating the display panel 100 to implement more hierarchical settings of pressure sensing, improving the accuracy of pressure sensing of the display panel 100, and improving the application scenarios of the display panel 100.

[0059] See also Figure 2 and Figure 3 In one embodiment, to improve the support stability of the overall structure of the display panel 100, the display panel 100 further includes a main spacer 80. The main spacer 80 is sandwiched between the first substrate 10 and the second substrate 20 to provide support for the first substrate 10 and the second substrate 20. Furthermore, a black matrix 14 is provided within the first substrate 10. The main spacer 80 and the black matrix 14 are arranged opposite each other along a first direction. The first spacer 41 and the second spacer 42 of the auxiliary spacer 40 are also arranged opposite each other along the first direction.

[0060] The display panel 100 provided in the first embodiment of the present application, on the one hand, has a main spacer 80 sandwiched between the first substrate 10 and the second substrate 20 to provide support for the first substrate 10 and the second substrate 20, thereby improving the support stability of the overall structure of the display panel 100. On the other hand, by providing the black matrix 14 on the first substrate 10, the main spacer 80 and the black matrix 14 are arranged relative to each other along the first direction, and the first spacer 41 and the second spacer 42 of the auxiliary spacer 40 are both arranged relative to the black matrix 14 along the first direction, the number of film layers at the light-transmitting portion of the display panel 100 can be reduced, thereby reducing the impact of the main spacer 80 and the auxiliary spacer 40 on the display effect of the display panel 100, thereby improving the light transmittance of the display panel 100.

[0061] See also Figures 2 to 4 In a specific embodiment, to limit the direction in which the elastic body 70 in the display panel 100 deforms under the action of the first spacer 41, the second spacer 42 has a groove 421 on the side facing the first spacer 41. The elastic body 70 is disposed within the groove 421 and located at the bottom of the groove 421. The end of the first spacer 41 facing the second spacer 42 is located within the groove 421 and abuts against the elastic body 70. A gap 422 is defined between the peripheral sidewall of the first spacer 41 and the inner sidewall of the groove 421. At least a portion of the liquid crystal in the liquid crystal layer 30 is located within the gap 422 and covers the peripheral sidewall of the first spacer 41.

[0062] In the display panel 100 provided in the first embodiment of the present application, a groove 421 is provided on the end of the second spacer 42 facing the first spacer 41. An elastic member 70 is disposed at the bottom of the groove 421. The end of the first spacer 41 facing the second spacer 42 is located within the groove 421 and abuts against the elastic member 70. Furthermore, a gap 422 is defined between the peripheral sidewall of the first spacer 41 and the inner sidewall of the groove 421. At least a portion of the liquid crystal in the liquid crystal layer 30 is located within the gap 422, that is, between the peripheral sidewall of the first spacer 41 and the inner sidewall of the groove 421. When the elastic member 70 is squeezed by the first spacer 41, it is confined by the space formed by the inner sidewall of the groove 421 and the peripheral sidewall of the first spacer 41. While enveloping the peripheral sidewall of the first spacer 41, the elastic member 70 deforms in a first direction toward the first substrate 10, without deforming in other directions. Thus, the deformation of the elastic body 70 will squeeze at least part of the liquid crystal in the gap 422 of the liquid crystal layer 30 out of the gap 422, so that the area of the solid-liquid interface formed by the peripheral side wall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes more significantly, thereby increasing the second capacitor C 21 More obvious changes occur, which is beneficial to further improve the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel 100.

[0063] More specifically, in the first direction, the depth of the groove 421 is greater than the sum of the height of the deformed elastic body 70 and the height of the elastic body 70 itself, so as to prevent the elastic body 70 from deforming outside the groove 421 during the deformation process.

[0064] More specifically, the peripheral sidewall of the elastic body 70 always keeps in contact with the inner sidewall of the groove 421 to prevent the elastic body 70 from falling out of the groove 421 and to enable the elastic body 70 to deform only in the first direction under the squeezing action of the first spacer 41 .

[0065] It can be understood that the shape of the groove 421 includes but is not limited to a "U"-shaped groove, a "V"-shaped groove, a "凵"-shaped groove, etc., and the present application does not limit this.

[0066] Please refer to Figure 2 , in a specific embodiment, during the process of the first spacer 41 moving towards the second spacer 42, the distance between the inner sidewall of the groove 421 and the peripheral sidewall of the first spacer 41 is fixed. In other words, the radial dimension of the groove 421 remains unchanged, and the radial dimension of the first spacer 41 remains unchanged. Thus, it is convenient to process and form the groove 421 and the first spacer 41, and the manufacturing process of the display panel 100 is simpler.

[0067] Please refer to Figure 3 , in some embodiments, the radial dimension of the groove 421 remains unchanged. From the end of the first spacer 41 of the display panel 100 facing the second spacer 42 to the end of the first spacer 41 facing away from the second spacer 42, the radial dimension of the first spacer 41 gradually increases. Or, the radial dimension of the first spacer 41 remains unchanged, and from the opening of the groove 421 of the display panel 100 to the bottom of the groove 421, the radial dimension of the groove 421 gradually increases. Or, from the end of the first spacer 41 of the display panel 100 facing the second spacer 42 to the end of the first spacer 41 facing away from the second spacer 42, the radial dimension of the first spacer 41 gradually increases. Moreover, from the opening of the groove 421 of the display panel 100 to the bottom of the groove 421, the radial dimension of the groove 421 gradually increases. Of course, in this embodiment, it is necessary to ensure that the first spacer 41 can penetrate into the groove 421 and form a gap 422 with the inner sidewall of the groove 421.

[0068] In the display panel 100 provided by the first embodiment of the present application, by keeping the radial dimension of the groove 421 unchanged and the radial dimension of the first spacer 41 gradually increasing along the direction from the second spacer 42 to the first spacer 41; or, keeping the radial dimension of the first spacer 41 unchanged and the radial dimension of the groove 421 gradually increasing along the direction from the first spacer 41 to the second spacer 42; or, the radial dimension of the first spacer 41 gradually increases along the direction from the second spacer 42 to the first spacer 41, and the radial dimension of the groove 421 gradually increases along the direction from the first spacer 41 to the second spacer 42. Thus, during the process of the first spacer 41 moving towards the second spacer 42 and squeezing the elastomer 70, the degree of deformation of the elastomer 70 will increase as the distance of the first spacer 41 moving towards the second spacer 42 increases, making the speed at which the elastomer 70 squeezes the liquid crystal in the gap 422 out of the gap 422 faster and faster. Furthermore, the change in the area of the solid-liquid interface formed between the peripheral sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 will become faster and faster, which is beneficial to further improving the second capacitance C21 The change is conducive to further improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel 100.

[0070] In a specific embodiment, the first electrode 50 of the display panel 100 extends along the first direction, and the peripheral sidewall of the first electrode 50 and the liquid crystal of the liquid crystal layer 30 form a third capacitor C 31 The elastic body 70 is configured to change the area of the positive projection of the elastic body 70 surrounding the peripheral side wall of the first electrode 50 under the action of the first spacer 41, so as to change the third capacitor C 31 size.

[0071] In the display panel 100 provided in the first embodiment of the present application, the first spacer 41 squeezes the elastic body 70 to change the area of the orthographic projection of the elastic body 70 surrounding the side wall of the first electrode 50, thereby changing the third capacitor C 31 Thus, when the display panel 100 is deformed by an external force, the first spacer 41 presses the elastic body 70 to increase the positive projection area of the side wall of the elastic body 70 surrounding the first electrode 50, thereby reducing the positive area between the side wall of the first electrode 50 and the liquid crystal of the liquid crystal layer 30, so that the third capacitor C 31 change.

[0072] See also Figures 2 to 7 In a specific embodiment, the end surface of the first electrode 50 of the display panel 100 facing the second electrode 60 and the liquid crystal of the liquid crystal layer 30 in contact with the elastic body 70 form a fourth capacitor C 41 , the fourth capacitor C 41 The size of varies with the displacement of the first electrode 50 along the first direction toward the second electrode 60. Thus, when the display panel 100 is deformed by an external force, the first spacer 41 moves toward the second spacer 42 to press the elastic body 70, thereby increasing the deformation of the elastic body 70, thereby increasing the distance between the end surface of the first electrode 50 facing the second electrode 60 and the liquid crystal of the liquid crystal layer 30 in contact with the elastic body 70, so that the fourth capacitor C 41 change.

[0073] See also Figure 2 and Figure 3In a specific embodiment, the second substrate 20 is provided with a common electrode 26 and a pixel electrode 25. The common electrode 26 is provided on the side of the second substrate 20 facing the first substrate 10, and the pixel electrode 25 is provided on the second substrate 20 away from the first substrate 10. The common electrode 26 includes a second electrode 60. In other words, when the common electrode 26 is provided on the side of the second substrate 20 facing the first substrate 10, the common electrode 26 and the second electrode 60 are shared or integrally formed, thereby reducing the overall manufacturing process of the display panel 100.

[0074] It can be understood that in some other embodiments, the second substrate 20 is provided with a common electrode 26 and a pixel electrode 25, the common electrode 26 is arranged at a position of the second substrate 20 away from the first substrate 10, and the pixel electrode 25 is arranged on the side of the second substrate 20 facing the first substrate 10, and the second electrode 60 is separately arranged from the pixel electrode 25 to facilitate electrical connection of the second electrode 60, and this application does not impose any restrictions on this.

[0075] See also Figures 2 to 8 , Figure 8 This is an equivalent capacitance circuit diagram of a display panel provided in the first embodiment of the present application.

[0076] In the first embodiment of the present application, the display panel 100 includes a first state and a second state. The first state is a state in which the display panel 100 is not affected by an external force, and the second state is a state in which the display panel 100 is deformed by an external force.

[0077] When the display panel 100 is in the first state, the first spacer 41 and the second spacer 42 are opposite each other and spaced apart along a first direction. The end of the first spacer 41 closest to the second spacer 42 is located within the groove 421 of the second spacer 42. The elastic member 70 is located at the bottom of the groove 421 of the second spacer 42 and sandwiched between the first spacer 41 and the second spacer 42. The side of the elastic member 70 closest to the first spacer 41 is approximately coplanar. The side of the elastic member 70 closest to the first spacer 41 is approximately parallel to the end surface of the first spacer 41 facing the second spacer 42. The peripheral sidewall of the elastic member 70 is in contact with the inner sidewall of the groove 421. At this time, at least a portion of the liquid crystal in the liquid crystal layer 30 is located within the gap 422 formed by the inner sidewall of the groove 421 and the peripheral sidewall of the first spacer 41.

[0078] Therefore, when the display panel 100 is in the first state, the display panel 100 has a fixed capacitance C 00 , fixed capacitor C 00 It is a fixed capacitor in the display panel 100. A first capacitor C is formed between the first electrode 50 and the second electrode 60. 11The solid-liquid interface formed between the sidewall of the first spacer 41 and the liquid crystal of the liquid crystal layer 30 constitutes the second capacitor C 21 A third capacitor C is formed between the sidewall of the first electrode 50 and the liquid crystal of the liquid crystal layer 30. 31 A fourth capacitor C is formed between the liquid crystal of the liquid crystal layer 30 in contact with the elastic body 70 and the end surface of the first electrode 50 facing the second electrode 60. 41 The first capacitor C 11 , the second capacitor C 21 , the third capacitor C 31 , the fourth capacitor C 41 and fixed capacitor C 00 The total capacitance of the display panel 100 in the first state is the first capacitance C 11 , the second capacitor C 21 , the third capacitor C 31 , the fourth capacitor C 41 and fixed capacitor C 00 sum.

[0079] When the display panel 100 is deformed by external force, the first spacer 41 moves toward the second spacer 42 along with the deformed first substrate 10. The first spacer 41 squeezes the elastomer 70, causing the elastomer 70 to deform. At least part of the liquid crystal in the liquid crystal layer 30 located in the gap 422 formed by the inner side wall of the groove 421 and the peripheral side wall of the first spacer 41 is squeezed out of the gap 422 by the elastomer 70.

[0080] When the display panel 100 is in the second state, the first spacer 41 moves toward the second spacer 42 and presses the elastomer 70, causing the elastomer 70 to deform. At least a portion of the peripheral sidewall of the first spacer 41 is covered by the elastomer 70, and at least a portion of the liquid crystal in the liquid crystal layer 30 located within the gap 422 is squeezed out of the gap 422 by the elastomer 70. At this time, the distance between the first electrode 50 and the second electrode 60 is reduced, the solid-liquid interface formed by the peripheral sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 is reduced, the orthographic projection of the liquid crystal in the liquid crystal layer 30 on the peripheral sidewall of the first electrode 50 is reduced, and the distance between the liquid crystal in the liquid crystal layer 30 in contact with the elastomer 70 and the end face of the first electrode 50 facing the second electrode 60 is increased.

[0081] Thus, when the display panel 100 is in the second state, a changed first capacitor C is formed between the first electrode 50 and the second electrode 60. 12 The solid-liquid interface formed between the sidewall of the first spacer 41 and the liquid crystal of the liquid crystal layer 30 constitutes the changed second capacitance C 22 A third capacitance C is formed between the sidewall of the first electrode 50 and the liquid crystal of the liquid crystal layer 30. 32A fourth capacitance C is formed between the liquid crystal of the liquid crystal layer 30 in contact with the elastic body 70 and the end surface of the first electrode 50 facing the second electrode 60. 42 The first capacitance C after the change 12 , the second capacitance C after the change 22 , the third capacitor C after the change 32 , the fourth capacitor C after the change 42 and fixed capacitor C 00 The total capacitance of the display panel 100 in the second state is the changed first capacitance C 12 , the second capacitance C after the change 22 , the third capacitor C after the change 32 , the fourth capacitor C after the change 42 and fixed capacitor C 00 sum.

[0082] The display panel 100 provided in the first embodiment of the present application includes a first capacitor C 11 The change of the second capacitor C 21 The change of the third capacitor C 31 The change in the fourth capacitor C 41 This greatly improves the total capacitance change of the display panel 100 before and after deformation by force. Therefore, the display panel 100 provided in this embodiment, under the same pressure, when the first substrate 10 is deformed relative to the second substrate 20, is conducive to improving the pressure sensing gradient of the pressure sensor integrated in the display panel 100, thereby improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel 100, facilitating the display panel 100 to implement more hierarchical settings of pressure sensing, improving the accuracy of pressure sensing of the display panel 100, and expanding the application scenarios of the display panel 100.

[0083] Second embodiment:

[0084] See also Figure 2 and Figure 9 , Figure 9 This is a cross-sectional structural diagram of a display panel provided in the second embodiment of the present application.

[0085] The display panel 100 provided in the second embodiment of the present application is substantially the same as the display panel 100 provided in the first embodiment of the present application, and includes a first substrate 10, a second substrate 20, a liquid crystal layer 30, an auxiliary spacer 40, a first electrode 50, a second electrode 60, an elastomer 70, and a main spacer 80. The difference is that the second spacer 42 of the auxiliary spacer 40 of the display panel 100 provided in the second embodiment of the present application has a planar structure at one end facing the first spacer 41.

[0086] The first substrate 10 and the second substrate 20 are opposite to each other and spaced apart along a first direction, and the liquid crystal layer 30 is filled between the first substrate 10 and the second substrate 20. The first direction is the stacking direction of the first substrate 10, the liquid crystal layer 30 and the second substrate 20.

[0087] The auxiliary spacer 40 is located in the liquid crystal layer 30. The auxiliary spacer 40 includes a first spacer 41 and a second spacer 42. The first spacer 41 and the second spacer 42 are both insulators. The first spacer 41 is arranged on the side of the first substrate 10 facing the second substrate 20 and is located in the liquid crystal layer 30. The second spacer 42 is arranged on the side of the second substrate 20 facing the first substrate 10 and is located in the liquid crystal layer 30. The first spacer 41 and the second spacer 42 are opposite to each other and spaced apart along the first direction.

[0088] The first electrode 50 is disposed in the first spacer 41. The second electrode 60 is disposed on the side of the second substrate 20 facing the first substrate 10. The second electrode 60 is completely sandwiched between the second spacer 42 and the second substrate 20, that is, the second spacer 42 completely covers the second electrode 60. The first electrode 50 and the second electrode 60 are opposite and spaced apart along the first direction, so that a first capacitor C is formed between the first electrode 50 and the second electrode 60. 11 .

[0089] The elastic body 70 is disposed between the first spacer 41 and the second spacer 42. The peripheral sidewall of the first spacer 41 forms a solid-liquid interface with the liquid crystal in the liquid crystal layer 30. The solid-liquid interface forms a second capacitor C 21 , the second capacitor C 21 The elastic body 70 is configured to change the area of the sidewall of the elastic body 70 covering the first spacer 41 under the action of the first spacer 41, thereby changing the area of the solid-liquid interface formed by the sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30, thereby changing the second capacitor C 21 size.

[0090] The main spacer 80 is sandwiched between the first substrate 10 and the second substrate 20 to support the first substrate 10 and the second substrate 20 .

[0091] The display panel 100 provided in the second embodiment of the present application is sandwiched between the first substrate 10 and the second substrate 20 through the liquid crystal layer 30 and the auxiliary spacer 40. The first electrode 50 is arranged in the first spacer 41 of the auxiliary spacer 40, and the second electrode 60 is arranged on the side of the second substrate 20 facing the first substrate 10, and the second spacer 42 completely covers the second electrode 60.

[0092] On the one hand, the first electrode 50 and the second electrode 60 are arranged opposite to each other and spaced apart along a first direction to form a first capacitor C 11 When the first substrate 10 is deformed relative to the second substrate 20, the first spacer 41 moves along with the first substrate 10, causing the distance between the first electrode 50 and the second electrode 60 to change, thereby causing the first capacitor C 11 Changes have occurred.

[0093] On the other hand, the elastic body 70 is disposed between the first spacer 41 and the second spacer 42. The peripheral sidewall of the first spacer 41 forms a solid-liquid interface with the liquid crystal of the liquid crystal layer 30. The solid-liquid interface forms a second capacitor C 21 , and the second capacitor C 21 The first spacer 41 moves along with the first substrate 10 and squeezes the elastic body 70. Under the action of the first spacer 41, the elastic body 70 changes the area of the sidewalls covering the first spacer 41, so that the area of the solid-liquid interface formed by the sidewalls of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes. That is, the area facing each other between the sidewalls of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes, thereby changing the second capacitance C. 21 Since the second capacitor C 21 The second capacitor C is an electric double layer capacitor with a very large capacitance. During the process in which the facing area between the peripheral sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes, the second capacitor C 21 The change in capacitance is also extremely large. Therefore, the display panel 100 provided in the second embodiment of the present application, under the same pressure, when the first substrate 10 is deformed relative to the second substrate 20, is conducive to improving the pressure sensing gradient of the pressure sensor integrated in the display panel 100, thereby improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel 100, facilitating the display panel 100 to implement more hierarchical settings of pressure sensing, improving the accuracy of pressure sensing of the display panel 100, and improving the application scenarios of the display panel 100.

[0094] On the other hand, the end of the second spacer 42 facing the first spacer 41 is a planar structure, which simplifies the manufacturing process of the second spacer 42 and helps improve the manufacturing efficiency of the display panel 100 .

[0095] See also Figure 9 In a specific embodiment, to limit the direction in which the elastic body 70 in the display panel 100 deforms under the action of the first spacer 41, along a first direction, the orthographic projection of the first spacer 41 on the elastic body 70 is completely located on the elastic body 70, and the orthographic projection of the elastic body 70 on the second spacer 42 is completely located on the second spacer 42. In other words, the area of the end surface of the first spacer 41 in contact with the elastic body 70 is smaller than the area of the end surface of the elastic body 70 in contact with the first spacer 41, and the area of the end surface of the second spacer 42 in contact with the elastic body 70 is larger than the area of the end surface of the elastic body 70 in contact with the second spacer 42.

[0096] The display panel 100 provided in the second embodiment of the present application is such that the orthographic projection of the first spacer 41 on the elastic body 70 is completely located on the elastic body 70, and the orthographic projection of the elastic body 70 on the second spacer 42 is completely located on the second spacer 42. When the first spacer 41 squeezes the elastic body 70, the elastic body 70 will deform along the direction of the second substrate 20 toward the first substrate 10 and in a direction parallel to the second substrate 20, but will not deform in the direction of the second spacer 42. Therefore, under the squeezing action of the first spacer 41, the elastic body 70 will cover at least a portion of the peripheral side wall of the first spacer 41 to change the area of the solid-liquid interface formed between the peripheral side wall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30, thereby making the second capacitor C 21 The capacitance changes.

[0097] Third embodiment:

[0098] See also Figure 2 and Figure 10 , Figure 10 This is a cross-sectional structural diagram of a display panel provided in the third embodiment of the present application.

[0099] The display panel 100 provided in the third embodiment of the present application is substantially the same as the display panel 100 provided in the first embodiment of the present application, and includes a first substrate 10, a second substrate 20, a liquid crystal layer 30, an auxiliary spacer 40, a first electrode 50, a second electrode 60, an elastomer 70, and a main spacer 80. The difference is that the auxiliary spacer 40 of the display panel 100 provided in the third embodiment of the present application omits the second spacer 42.

[0100] The first substrate 10 and the second substrate 20 are opposite to each other and spaced apart along a first direction, and the liquid crystal layer 30 is filled between the first substrate 10 and the second substrate 20. The first direction is the stacking direction of the first substrate 10, the liquid crystal layer 30 and the second substrate 20.

[0101] The auxiliary spacer 40 is located in the liquid crystal layer 30 and includes a first spacer 41 . The first spacer 41 is an insulator and is disposed on a side of the first substrate 10 facing the second substrate 20 and located in the liquid crystal layer 30 .

[0102] The first electrode 50 is disposed in the first spacer 41. The second electrode 60 is disposed on the side of the second substrate 20 facing the first substrate 10. The first electrode 50 and the second electrode 60 are disposed opposite to each other along the first direction and spaced apart so that a first capacitor C is formed between the first electrode 50 and the second electrode 60. 11 .

[0103] The elastic body 70 is disposed between the first spacer 41 and the second substrate 20. The elastic body 70 completely covers the second electrode 60. The peripheral sidewall of the first spacer 41 forms a solid-liquid interface with the liquid crystal in the liquid crystal layer 30. The solid-liquid interface forms a second capacitor C 21 , the second capacitor C 21 The elastic body 70 is configured to change the area of the sidewall of the elastic body 70 covering the first spacer 41 under the action of the first spacer 41, thereby changing the area of the solid-liquid interface formed by the sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30, thereby changing the second capacitor C 21 size.

[0104] The main spacer 80 is sandwiched between the first substrate 10 and the second substrate 20 to support the first substrate 10 and the second substrate 20 .

[0105] The display panel 100 provided in the third embodiment of the present application is sandwiched between the first substrate 10 and the second substrate 20 through the liquid crystal layer 30 and the auxiliary spacer 40. The first electrode 50 is arranged in the first spacer 41 of the auxiliary spacer 40, and the second electrode 60 is arranged on the side of the second substrate 20 facing the first substrate 10, and the second spacer 42 completely covers the second electrode 60.

[0106] On the one hand, the first electrode 50 and the second electrode 60 are arranged opposite to each other and spaced apart along a first direction to form a first capacitor C 11 When the first substrate 10 is deformed relative to the second substrate 20, the first spacer 41 moves along with the first substrate 10, causing the distance between the first electrode 50 and the second electrode 60 to change, thereby causing the first capacitor C 11 Changes have occurred.

[0107] On the other hand, the elastic body 70 is disposed between the first spacer 41 and the second spacer 42. The peripheral sidewall of the first spacer 41 forms a solid-liquid interface with the liquid crystal of the liquid crystal layer 30. The solid-liquid interface forms a second capacitor C 21 , and the second capacitor C 21 The first spacer 41 moves along with the first substrate 10 and squeezes the elastic body 70. Under the action of the first spacer 41, the elastic body 70 changes the area of the sidewalls covering the first spacer 41, so that the area of the solid-liquid interface formed by the sidewalls of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes. That is, the area facing each other between the sidewalls of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes, thereby changing the second capacitance C. 21 Since the second capacitor C 21 The second capacitor C is an electric double layer capacitor with a very large capacitance. When the facing area between the side wall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30 changes, the second capacitor C 21 The change in capacitance is also extremely large. Therefore, the display panel 100 provided in the third embodiment of the present application, under the same pressure, when the first substrate 10 is deformed relative to the second substrate 20, is conducive to improving the pressure sensing gradient of the pressure sensor integrated in the display panel 100, thereby improving the pressure sensing linearity and the fineness of the pressure sensing force gradient of the pressure sensor integrated in the display panel 100, facilitating the display panel 100 to implement more hierarchical settings of pressure sensing, improving the accuracy of pressure sensing of the display panel 100, and improving the application scenarios of the display panel 100.

[0108] On the other hand, the auxiliary spacers 40 of the display panel 100 omit the second spacers 42 , which simplifies the manufacturing process of the display panel 100 , improves the manufacturing efficiency of the display panel 100 , and reduces the manufacturing cost of the display panel 100 .

[0109] See also Figure 10 In a specific embodiment, to limit the direction in which the elastic body 70 in the display panel 100 deforms under the action of the first spacer 41, the orthographic projection of the first spacer 41 on the elastic body 70 is completely located on the elastic body 70 along the first direction. In other words, the area of the end surface of the first spacer 41 in contact with the elastic body 70 is smaller than the area of the end surface of the elastic body 70 in contact with the first spacer 41.

[0110] The display panel 100 provided in the third embodiment of the present application has the first spacer 41 with its orthographic projection on the elastic body 70 completely located on the elastic body 70. When the first spacer 41 presses the elastic body 70, the elastic body 70 will deform in the direction from the second substrate 20 toward the first substrate 10 and in a direction parallel to the second substrate 20. Therefore, under the pressure of the first spacer 41, the elastic body 70 will cover at least a portion of the peripheral sidewall of the first spacer 41 to change the area of the solid-liquid interface formed between the peripheral sidewall of the first spacer 41 and the liquid crystal in the liquid crystal layer 30, thereby increasing the second capacitor C 21 The capacitance changes.

[0111] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application.
