[0002] A liquid crystal display (LCD) panel includes an array substrate and a counter substrate that are opposite and spaced apart, with a liquid crystal layer sandwiched between them. The array substrate and the counter substrate are bonded together using a sealant located between the array substrate and the counter substrate, and the sealant surrounds the liquid crystal layer to achieve a seal.

[0003] During the manufacturing process, when the liquid crystal display panel is subjected to external force, the frame adhesive is easily deformed and peels off from the array substrate or the opposing substrate. The liquid crystal layer will leak from the peeling point, resulting in display failure. Summary of the Invention

[0005] To achieve the above objectives, according to a first aspect of this application, a display panel is provided, comprising: An array substrate includes a main body and an extension disposed on one side of the main body, wherein the main body and the extension are connected along a first direction; The opposing substrate is positioned opposite to and spaced apart from the main body portion; A liquid crystal layer is disposed between the main body and the opposing substrate; A sealing portion is disposed between the main body portion and the opposing substrate, and the sealing portion is disposed around the liquid crystal layer; A conductive portion is located outside the sealing portion and is electrically connected to the extension portion and the opposing substrate; The display panel further includes a reinforcing portion located outside the sealing portion and connected to the extension portion and the opposing substrate.

[0006] Optionally, the reinforcing portion covers the edge of the opposing substrate and the edge of the extension portion near the main body portion.

[0010] Optionally, the reinforcing portion extends beyond the edge of the sealing portion in the second direction, and the reinforcing portion is spaced apart from the edge of the display panel in the second direction.

[0011] Optionally, the reinforcing portion extends beyond the sealing portion by a first dimension in the second direction, and the reinforcing portion extends by a second dimension in the second direction, wherein the first dimension is less than half of the second dimension.

[0012] Optionally, the orthographic projection of the reinforcing portion on the array substrate and the orthographic projection of the sealing portion on the array substrate are spaced apart in the first direction.

[0013] Optionally, the reinforcing portion includes a first portion that overlaps with the opposing substrate in the thickness direction of the display panel and a second portion that overlaps with the extension portion in the thickness direction of the display panel, wherein the dimension of the first portion in the first direction is smaller than the dimension of the second portion in the first direction.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0022] According to the first aspect of this application, Figures 1 to 3 As shown, a display panel 1 is provided, including an array substrate 11, an opposing substrate 12, a liquid crystal layer 13, a sealing portion 14, and a conductive portion 15. The array substrate 11 includes a main body 111 and an extension portion 112 disposed on one side of the main body 111. The main body 111 and the extension portion 112 are connected along a first direction D1. The opposing substrate 12 is disposed opposite to and spaced apart from the main body 111. The liquid crystal layer 13 is disposed between the main body 111 and the opposing substrate 12. The sealing portion 14 is disposed between the main body 111 and the opposing substrate. Between 12, and the sealing part 14 is disposed on the periphery of the liquid crystal layer 13; the conductive part 15 is located outside the sealing part 14 and is electrically connected to the extension part 112 and the opposing substrate 12; wherein, the display panel 1 also includes a reinforcing part 16, which is located outside the sealing part 14 and is connected to the extension part 112 and the opposing substrate 12. The reinforcing part 16 is located in the second direction D2, closer to the edge of the display panel 1 than the conductive part 15. The second direction D2 is perpendicular to the first direction D1 and the thickness direction of the display panel 1.

[0023] Display panel 1 can be an LCD (Liquid Crystal Display) panel.

[0024] In some embodiments, the display panel 1 can be any one of the following types: Vertical Alignment (VA), Twisted Nematic (TN), Super Twisted Nematic (STN), In-Plane Switching (IPS), and Fringe Field Switching (FFS).

[0025] like Figure 1As shown, the display panel 1 includes a display area AA and a non-display area NA disposed around the display area AA. The display area AA may have multiple sub-pixels 10, which may include a first sub-pixel 10, a second sub-pixel 10, and a third sub-pixel 10 of different emitting colors. The first sub-pixel 10, the second sub-pixel 10, and the third sub-pixel 10 may be one of red, green, and blue sub-pixels, respectively, thereby achieving color display. The display area AA is provided with a pixel driving circuit, which drives the sub-pixels 10 for display. The non-display area NA may have a gate driving circuit, etc., which provides driving signals to the sub-pixels 10.

[0026] The array substrate 11 may include a first substrate and a driving circuit layer disposed on the side of the first substrate near the liquid crystal layer 13.

[0027] In some embodiments, the first substrate can be a rigid material or a flexible material. The rigid material can be glass, quartz, or silicon. The flexible material can be one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).

[0028] The driving circuit layer contains driving circuits, such as gate driving circuits and pixel driving circuits, which are used to provide driving signals to the sub-pixel 10. The driving circuit layer may include multiple thin-film transistors, capacitors, etc. Each thin-film transistor includes a source, drain, gate, and active portion.

[0029] In some embodiments, the array substrate 11 further includes a pixel electrode located on the side of the driving circuit layer away from the first substrate, the pixel electrode being used to provide a pixel voltage to the liquid crystal layer 13.

[0030] The opposing substrate 12 may include a second substrate and a color filter layer disposed on the side of the second substrate near the liquid crystal layer 13. The material of the second substrate may be the same as or different from the material of the first substrate.

[0031] In some embodiments, the second substrate can be a rigid material or a flexible material. The rigid material can be glass, quartz, or silicon. The flexible material can be one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).

[0032] The color filter layer may include multiple color blocks and a black matrix disposed between two adjacent color blocks. The color blocks may include red, green, and blue color blocks. The red color block allows red light to pass through while blocking other colors; the green color block allows green light to pass through while blocking other colors; and the blue color block allows blue light to pass through while blocking other colors. The color filter layer can convert white light into the corresponding colored light. The black matrix is ​​a light-blocking material that blocks any color of light from passing through, thereby preventing color crosstalk between light emitted from two adjacent color blocks.

[0033] In other embodiments, the color filter layer may also be disposed between the first substrate and the liquid crystal layer 13, that is, the display panel 1 may be a COA (Color Filter on Array) architecture.

[0034] In some embodiments, the opposing substrate 12 further includes a common electrode layer located on the side of the second substrate near the liquid crystal layer 13, the common electrode layer being used to provide a common voltage to the liquid crystal layer 13.

[0035] In other embodiments, the common electrode layer may also be disposed between the driving circuit layer and the liquid crystal layer 13, that is, both the pixel electrode and the common electrode layer may be disposed between the first substrate and the liquid crystal layer 13.

[0036] like Figure 1 and Figure 3 As shown, the opposing substrate 12 and the main body 111 are positioned opposite each other and spaced apart. The external dimensions of the opposing substrate 12 and the main body 111 can be approximately the same. The external dimensions of the opposing substrate 12 refer to the dimensions of the opposing substrate 12 in a plane perpendicular to the thickness direction of the display panel 1, and the external dimensions of the main body 111 refer to the dimensions of the main body 111 in a plane perpendicular to the thickness direction of the display panel 1.

[0037] like Figure 1 and Figure 3 As shown, the main body 111 and the extension 112 are connected along the first direction D1. The main body 111 and the extension 112 are integrally formed, that is, the main body 111 and the extension 112 are made of the same material and are continuously formed.

[0038] In some embodiments, the extension 112 is provided with a bonding portion, which includes a plurality of bonding terminals and is used to connect with a bonding member. The bonding member includes a flexible circuit board, a printed circuit board, a driver chip, etc.

[0039] When the display panel 1 is an LCD panel, the LCD panel itself does not emit light, so a backlight module 3 needs to be set on one side of the display panel 1. The backlight module 3 provides a backlight source for the display panel 1. The light emitted from the backlight module 3 enters the display panel 1, and the liquid crystal molecules in the liquid crystal layer 13 of the display panel 1 are deflected under the action of the electric field formed by the pixel electrode and the common electrode layer. The light transmittance corresponding to the liquid crystal molecules at different deflection angles is different, thereby controlling the light transmittance of the display panel 1 and realizing the brightness control of the displayed image.

[0040] like Figure 2 and Figure 3 As shown, the sealing portion 14 is located between the main body portion 111 and the opposing substrate 12, and the sealing portion 14 is disposed on the periphery of the liquid crystal layer 13. The sealing portion 14 is used to seal the liquid crystal layer 13.

[0041] In some embodiments, the sealing portion 14 may be disposed around the liquid crystal layer 13. The sealing portion 14 may be a frame adhesive, which can bond the main body portion 111 to the opposing substrate 12 on the one hand, and seal the liquid crystal layer 13 on the other hand to prevent leakage of the liquid crystal layer 13.

[0042] like Figure 1 and Figure 2 As shown, the conductive portion 15 is located outside the sealing portion 14. This means that the orthographic projection of the conductive portion 15 on the array substrate 11 is located outside the orthographic projection of the sealing portion 14 on the array substrate 11. The sealing portion 14 is a closed pattern. The inner side of the sealing portion 14 is the area enclosed by the sealing portion 14, and the liquid crystal layer 13 is located within the area enclosed by the sealing portion 14. The outer side of the sealing portion 14 is the area outside the enclosed area.

[0043] like Figure 2 and Figure 3 As shown, the conductive part 15 is electrically connected to the extension part 112 and the opposing substrate 12. The conductive part 15 can be used to conduct static electricity on the opposing substrate 12 to the array substrate 11 and ground it through the circuit on the array substrate 11, thereby reducing the risk of the display panel 1 being damaged by electrostatic discharge.

[0044] In some embodiments, the conductive portion 15 may be formed of conductive silver paste, but is not limited thereto.

[0045] like Figure 1 and Figure 2As shown, the reinforcing portion 16 is located outside the sealing portion 14, that is, the reinforcing portion 16 is located outside the region enclosed by the sealing portion 14. In the second direction D2, the reinforcing portion 16 is closer to the edge of the display panel 1 than the conductive portion 15. That is to say, in the second direction D2, the distance between the reinforcing portion 16 and the edge of the display panel 1 is smaller than the distance between the conductive portion 15 and the edge of the display panel 1. When an external force is applied to the display panel 1, since the reinforcing portion 16 is closer to the edge of the display panel 1, the lever arm between the sealing portion 14 and the reinforcing portion 16 can be reduced, thereby reducing the torque received by the sealing portion 14 and lowering the risk of peeling between the sealing portion 14 and the array substrate 11 or the counter substrate 12.

[0046] It should be noted that the torque M received by the sealing portion 14 = (F1 - F2) * L, where F1 is the external pressure, F2 is the internal support force, and L is the lever arm of the force received by the sealing portion 14. When the reinforcing portion 16 is not provided on the display panel 1, the lever arm between the sealing portion 14 and the conductive portion 15 is L1. When the reinforcing portion 16 is provided on the display panel 1, the lever arm between the sealing portion 14 and the reinforcing portion 16 is L2. Since the reinforcing portion 16 is closer to the edge of the display panel 1 than the conductive portion 15 in the second direction D2, L2 < L1. When the external pressure F1 and the internal support force F2 remain unchanged, the torque received by the sealing portion 14 is smaller, thereby reducing the risk of peeling between the sealing portion 14 and the array substrate 11 or the counter substrate 12.

[0047] The second direction D2 is perpendicular to the first direction D1 and the thickness direction of the display panel 1. The thickness direction of the display panel 1 refers to the direction from the main body portion 111 to the counter substrate 12. The plane where the first direction D1 and the second direction D2 are located is the display plane, and the second direction D2 is perpendicular to the first direction D1.

[0048] Optionally, as Figure 2 and Figure 3 shown, the reinforcing portion 16 covers the edge of the counter substrate 12 and the edge of the extension portion 112 close to the main body portion 111. That is to say, the reinforcing portion 16 covers the edge of the counter substrate 12, and the reinforcing portion 16 covers the edge of the extension portion 112 close to the main body portion 111. Through the above arrangement, the reinforcing portion 16 can press the edge of the counter substrate 12 and the edge of the extension portion 112, reducing the risk of peeling between the counter substrate 12 and the array substrate 11 after being stressed.

[0049] In some embodiments, as Figure 2 and Figure 3 shown, the reinforcing portion 16 is in direct contact with the edge of the counter substrate 12, and the reinforcing portion 16 is in direct contact with the edge of the extension portion 112 close to the main body portion 111.

[0050] Optionally, the material of the reinforcing portion 16 is the same as that of the conductive portion 15.

[0051] When the material of the conductive part 15 is conductive silver paste, the material of the reinforcing part 16 can also be conductive silver paste. By setting the reinforcing part 16 to be made of the same material as the conductive part 15, the reinforcing part 16 can be formed using the same process as the conductive part 15, thereby simplifying the manufacturing process of the reinforcing part 16.

[0052] In some embodiments, the reinforcing part 16 may also be a single-sided adhesive tape, and the reinforcing part 16 may be bonded to the edge of the opposing substrate 12 and the edge of the extension 112 near the main body 111.

[0053] Optionally, such as Figure 4 As shown, Figure 4 The embodiments and Figure 2 The difference in the embodiment lies in the reinforcing part 16. The reinforcing part 16 is integrally provided with the conductive part 15, and the reinforcing part 16 continuously covers the edge of the opposing substrate 12 along the second direction D2.

[0054] The reinforcing portion 16 is integrally formed with the conductive portion 15, meaning that the material of the reinforcing portion 16 is the same as that of the conductive portion 15, and the reinforcing portion 16 and the conductive portion 15 are continuously disposed. This arrangement increases the contact area between the reinforcing portion 16 and the opposing substrate 12 and the extension portion 112, increases the force exerted by the reinforcing portion 16 on the opposing substrate 12 and the extension portion 112, and further reduces the risk of the opposing substrate 12 and the array substrate 11 peeling off from each other under stress.

[0055] Optionally, such as Figure 2 and Figure 4 As shown, the dimension s1 of the reinforcing part 16 in the first direction D1 is smaller than the dimension s2 of the conductive part 15 in the first direction D1. This arrangement reduces the dimension s1 of the reinforcing part 16 in the first direction D1, thereby saving material costs for the reinforcing part 16.

[0056] In some embodiments, such as Figure 4 As shown, the reinforcing part 16 and the conductive part 15 are connected to form an L-shape. The length of the reinforcing part 16 in the second direction D2 can be greater than the length of the conductive part 15 in the second direction D2.

[0057] Optionally, such as Figure 2 and Figure 4 As shown, the reinforcing part 16 extends beyond the edge of the sealing part 14 in the second direction D2, and the reinforcing part 16 is spaced apart from the edge of the display panel 1 in the second direction D2.

[0058] In some embodiments, such as Figure 2 and Figure 4As shown, the reinforcing portion 16 extends beyond the edge of the sealing portion 14 in the second direction D2. That is to say, in the second direction D2, the reinforcing portion 16 is closer to the edge of the display panel 1 than the sealing portion 14. With the above arrangement, the reinforcing portion 16 can extend beyond the corner of the sealing portion 14 in the second direction D2.

[0059] In some embodiments, the orthographic projection of the sealing portion 14 onto the array substrate 11 can be a rectangle, with the corners of the sealing portion 14 corresponding to the vertices of the rectangle. When the display panel 1 is deformed by force, the corners of the sealing portion 14 are more easily peeled off from the array substrate 11 and the opposing substrate 12. By extending the reinforcing portion 16 beyond the sealing portion 14 in the second direction D2, the requirements for the process accuracy of the reinforcing portion 16 can be reduced. Even if there are process deviations in the position of the reinforcing portion 16, the shortest lever arm can be achieved between the sealing portion 14 and the reinforcing portion 16. The shortest lever arm between the sealing portion 14 and the reinforcing portion 16 is the distance between the sealing portion 14 and the reinforcing portion 16 in the first direction D1. When the lever arm is shortest, the torque on the sealing portion 14 is minimal, thereby further reducing the risk of the sealing portion 14 peeling off from the array substrate 11 or the opposing substrate 12.

[0060] Specifically, the torque M on the sealing portion 14 is M = (F1 - F2) * L, where F1 is the external pressure, F2 is the internal support force, and L is the lever arm of the force on the frame adhesive. Since the reinforcing portion 16 extends beyond the edge of the sealing portion 14 in the second direction D2, and L is the distance between the sealing portion 14 and the reinforcing portion 16 in the first direction D1, the torque on the sealing portion 14 is smaller when the external pressure F1 and the internal support force F2 remain constant, thereby reducing the risk of the sealing portion 14 peeling off from the array substrate 11 or the opposing substrate 12.

[0061] In some embodiments, the reinforcing portion 16 is disposed at a distance from the edge of the display panel 1 in the second direction D2. That is, the reinforcing portion 16 does not extend to the sidewall of the array substrate 11. This arrangement avoids increasing the overall size of the display panel 1 by including the reinforcing portion 16. It also prevents the sidewall of the array substrate 11 from becoming uneven if the reinforcing portion 16 extends to it. When the sidewall of the array substrate 11 is uneven, after the display panel 1 is assembled with the backlight, the reinforcing portion 16 is prone to interference with the backlight module 3, potentially causing damage to the array substrate 11.

[0062] Optionally, such as Figure 2 and Figure 4 As shown, the reinforcing part 16 extends beyond the sealing part 14 in the second direction D2 by a first dimension s5, and the reinforcing part 16 extends beyond the sealing part 14 in the second direction D2 by a second dimension s6. The first dimension s5 is less than half of the second dimension s6.

[0063] In some embodiments, such as Figure 2 and Figure 4As shown, to avoid the first dimension s5 of the reinforcing part 16 being too large, which would increase the size of the bezel of the display panel 1, the first dimension s5 can be set to be less than half of the second dimension s6, that is, s5 < 1 / 2 * s6. This means that in the second direction D2, most of the reinforcing part 16 is located on the side of the sealing part 14 away from the edge of the display panel 1, and a small part of the reinforcing part 16 extends beyond the sealing part 14.

[0064] In related technologies, the separation between the sealing portion 14 and the array substrate 11 or the opposing substrate 12 is improved by increasing the width of the sealing portion 14. However, increasing the width of the sealing portion 14 will increase the width of each bezel, reducing the competitiveness of the display panel 1.

[0065] In the embodiments of this application, the reinforcement 16 does not additionally increase the width of the bezel. It should be noted that the bezel width refers to the width of the non-display area NA at each edge of the display panel 1. For example, as... Figure 1 As shown, the width of the left bezel of the display panel 1 refers to the dimension of the non-display area NA to the left of the display area AA in the second direction D2. The width of the right bezel of the display panel 1 refers to the dimension of the non-display area NA to the right of the display area AA in the second direction D2. The width of the bottom bezel of the display panel 1 refers to the width of the non-display area NA below the display area AA in the first direction D1. The extension 112 is located on the bottom bezel. Since the width of the bottom bezel of the display panel 1 is usually greater than the width of the left and right bezels, the bottom bezel has sufficient area to accommodate the reinforcing portion 16. In this application, the reinforcing portion 16 is provided on the bottom bezel without additionally increasing the width of the bottom bezel.

[0066] Optionally, such as Figures 2 to 4 As shown, the orthographic projection of the reinforcing part 16 on the array substrate 11 and the orthographic projection of the sealing part 14 on the array substrate 11 are spaced apart in the first direction D1. This means that there is a gap between the orthographic projection pattern of the reinforcing part 16 on the array substrate 11 and the orthographic projection pattern of the sealing part 14 on the array substrate 11 in the first direction D1. This arrangement prevents the reinforcing part 16 from entering the display area AA of the display panel 1 and obstructing the display screen.

[0067] In some embodiments, such as Figure 3 As shown, the display panel 1 also includes a first polarizer 171 disposed on the side of the opposing substrate 12 away from the array substrate 11, and a second polarizer 172 disposed on the side of the array substrate 11 away from the opposing substrate 12. The area of ​​the orthographic projection of the first polarizer 171 onto the array substrate 11 is smaller than the area of ​​the orthographic projection of the opposing substrate 12 onto the array substrate 11, that is, the edge of the first polarizer 171 does not extend beyond the edge of the opposing substrate 12.

[0068] In some embodiments, such as Figure 3As shown, the reinforcing portion 16 covers the edge of the opposing substrate 12, but does not cover the edge of the first polarizer 171. This arrangement prevents the reinforcing portion 16 from overlapping with the first polarizer 171, thereby avoiding excessive increase in the thickness of the display panel 1 due to the reinforcing portion 16.

[0069] Optionally, such as Figure 2 and Figure 4 As shown, the reinforcing part 16 includes a first part 161 that overlaps with the opposing substrate 12 in the thickness direction of the display panel 1 and a second part 162 that overlaps with the extension part 112 in the thickness direction of the display panel 1. The dimension s3 of the first part 161 in the first direction D1 is smaller than the dimension s4 of the second part 162 in the first direction D1.

[0070] In some embodiments, such as Figure 2 and Figure 4 As shown, the reinforcing portion 16 includes a first portion 161 that overlaps with the opposing substrate 12 and a second portion 162 that overlaps with the extension portion 112. That is, the first portion 161 overlaps with the opposing substrate 12 in the thickness direction of the display panel 1, and the second portion 162 is offset from the opposing substrate 12 in the thickness direction of the display panel 1. The second portion 162 is offset from the opposing substrate 12 in the thickness direction of the display panel 1, and the second portion 162 overlaps with the extension portion 112 in the thickness direction of the display panel 1.

[0071] like Figures 2 to 4 As shown, the dimension s3 of the first part 161 in the first direction D1 is smaller than the dimension s4 of the second part 162 in the first direction D1. This means that in the first direction D1, the smaller portion of the reinforcing part 16 covers the opposing substrate 12, and the larger portion of the reinforcing part 16 covers the extension part 112. This arrangement reduces the requirements for the manufacturing precision of the reinforcing part 16. When the reinforcing part 16 is formed on the opposing substrate 12, even with positional deviations, the reinforcing part 16 is less likely to cover the first polarizer 171.

[0072] In some embodiments, the surface of the reinforcing portion 16 may have a corrugated structure. The surface of the reinforcing portion 16 refers to the side of the reinforcing portion 16 away from the array substrate 11. When the display panel 1 is subjected to external force, the corrugated structure is more likely to deform to release displacement. When the reinforcing portion 16 is made of silver paste, the corrugated structure of the reinforcing portion 16 formed with silver can release displacement better because silver has good ductility.

[0073] It should be noted that the wrinkled structure refers to the uneven surface of the reinforcing part 16. The wrinkled structure can be an irregular pattern or a regular pattern, and this application does not limit this. The uneven surface includes protrusions and grooves located between the protrusions. The depth of the grooves is less than the height of the protrusions, that is, the grooves do not completely penetrate the reinforcing part 16 in the thickness direction of the display panel 1, thereby avoiding the grooves reducing the mechanical strength of the reinforcing part 16.

[0074] In some embodiments, the outline of the orthographic projection pattern of the reinforcing portion 16 on the array substrate 11 can be non-linear. For example, the outline of the orthographic projection pattern of the reinforcing portion 16 on the array substrate 11 can be serrated, wavy, or the like. With the above arrangement, when the reinforcing portion 16 is subjected to external force, the external force can be dispersed along the extension direction of the outline of the edge of the reinforcing portion 16. Since the outline of the edge of the reinforcing portion 16 is non-linear, the force can be dispersed in different directions, thereby avoiding the external force from being concentrated on the same point of the reinforcing portion 16.

[0075] In some embodiments, the surface of the reinforcing portion 16 may have a corrugated structure, and the outline of the orthographic projection pattern of the reinforcing portion 16 on the array substrate 11 may be non-linear. Through the above configuration, the reinforcing portion 16 can better distribute external forces, further reducing the torque on the sealing portion 14 and lowering the risk of the sealing portion 14 peeling off from the array substrate 11 or the opposing substrate 12.

[0076] According to the second aspect of this application, such as Figure 5 As shown, a display terminal 2 is provided, including the display panel 1 described above.

[0077] In some embodiments, such as Figure 5 As shown, the display terminal 2 includes a backlight module 3 and a display panel 1, which are combined into one unit. The backlight module 3 is used to provide a backlight source for the display panel 1.

[0078] The light-emitting surface of the backlight module 3 is set to correspond to the display area AA of the display panel 1. This means that the backlight module 3 can provide a planar light source for at least the entire display area AA of the display panel 1.

[0079] In some embodiments, the display terminal 2 may further include a front frame, which is used to fix the display panel 1 to the backlight module 3. The front frame may also protect the edge of the display panel 1 to prevent the display panel 1 from being damaged by external forces.

[0080] In this embodiment, the display terminal 2 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0082] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0083] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0084] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
