[0060] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a display panel provided by the first embodiment of the present application.

[0061] Refer to Figure 1 , embodiments of the present application provide a display panel 100, including a display area AA and a non-display area NA provided on the periphery of the display area AA. The display panel 100 includes an array substrate 10 and a sealant 20. Among them, the array substrate 10 includes a gate driving circuit 10a. The sealant 20 is disposed on one side of the array substrate 10 and is located in the non-display area NA.

[0062] Among them, the array substrate 10 further includes a plurality of metal protection lines 11 that are spaced apart from each other and insulated in the non-display area NA. The plurality of metal protection lines 11 are located between the sealant 20 and the gate driving circuit 10a.

[0063] It should be noted that Figure 1 the number of the metal protection lines 11 shown is two, which is only for illustration and does not represent a limitation on the number of the metal protection lines 11. The number of the metal protection lines 11 can be two, three, or other numbers, which are specifically set according to needs.

[0064] In some embodiments, the gate driving circuit 10a may include a plurality of GOA (Gate On Array) driving units for driving the gate lines of the array substrate 10, thereby driving the display and light emission of the display panel 100. Each GOA driving unit includes a plurality of thin film transistors (TFTs) and at least one capacitor. The gate driving circuit 10a may be disposed in the display area AA (as Figure 20 shown); it may also be disposed in the non-display area NA (as Figure 1 shown); or it may be partially disposed in the display area AA and partially disposed in the non-display area NA (not shown in the figure).

[0065] In some embodiments, the display panel 100 is an LCD display panel. Refer to Figure 19 , the LCD display panel includes an array substrate 10, a counter substrate 60, a liquid crystal layer 70, and sealant 20. The counter substrate 60 is disposed at an interval from the array substrate 10. The liquid crystal layer 70 is disposed between the array substrate 10 and the counter substrate 60. The sealant 20 is disposed between the array substrate 10 and the counter substrate 60 and is located in the non-display area NA. The sealant 20 surrounds the gate driving circuit 10a. Among them, a plurality of metal protection lines 11 are located between the sealant 20 and the gate driving circuit 10a.

[0066] In some embodiments, the counter substrate 60 is a color filter substrate for filtering light in a specific wavelength range to adjust the color displayed by the display panel 100 and achieve color display.

[0067] In some embodiments, the liquid crystal layer 70 includes liquid crystal molecules, photoinitiators, and polymerizable monomers that can undergo a polymerization reaction under ultraviolet light irradiation. Among them, the liquid crystal molecules are nematic liquid crystal molecules with a negative dielectric anisotropy constant.

[0068] In some embodiments, the sealant 20 has adhesiveness and may include one or several materials such as acrylic sealant, epoxy resin sealant, polyurethane sealant, and silicone sealant. The sealant 20 surrounds the liquid crystal layer 70 and can simultaneously contact two main surfaces of the array substrate 10 and the counter substrate 60 that are oppositely disposed, thereby bonding the array substrate 10 and the counter substrate 60 through the adhesiveness of the sealant 20 and blocking external factors such as moisture to a certain extent from entering the liquid crystal layer 70. Among them, the external factors include but are not limited to moisture, dust impurities, etc.

[0069] In some embodiments, the display panel 100 is an LED (light emitting diode) display panel. Refer to Figure 20, the LED display panel includes an array substrate 10, a cover plate 81, light-emitting diodes 82, encapsulation resin 83, and sealant 20. The gate driving circuit 10a is disposed in the display area AA. The light-emitting diodes 82 are disposed on one side of the gate driving circuit 10a. The encapsulation resin 83 covers the light-emitting diodes 82 and is located in the display area AA. The cover plate 81 is disposed on the side of the encapsulation resin 83 away from the array substrate 10. The sealant 20 is disposed between the array substrate 10 and the cover plate 81 and is located in the non-display area NA. The sealant 20 surrounds the gate driving circuit 10a. Among them, a plurality of metal protection lines 11 are located between the sealant 20 and the gate driving circuit 10a.

[0070] In some embodiments, the display panel 100 may be an OLED (organic light-emitting diode) display panel. Refer to Figure 21 , the dam 21 of the OLED display panel functions similarly to the sealant 20. The OLED display panel includes an array substrate 10, a cathode electrode layer 91, an organic light-emitting layer 92, an anode electrode layer 93, an encapsulation layer 94, and a dam 21. The gate driving circuit 10a is disposed in the display area AA. The anode electrode layer 93 is disposed on one side of the gate driving circuit 10a. The organic light-emitting layer 92 is disposed on the side of the anode electrode layer 93 away from the gate driving circuit 10a. The cathode electrode layer 91 is disposed on the side of the organic light-emitting layer 92 away from the gate driving circuit 10a. The encapsulation layer 94 covers the cathode electrode layer 91, the metal protection lines 11, and the dam 21. The dam 21 is disposed between the array substrate 10 and the encapsulation layer 94 and is located in the non-display area NA. The dam 21 surrounds the gate driving circuit 10a. Among them, a plurality of metal protection lines 11 are located between the dam 21 and the gate driving circuit 10a.

[0071] The sealant 20 blocks external factors such as moisture from entering the display area AA of the array substrate 10 to a certain extent. Among them, the external factors include, but are not limited to, moisture, dust, impurities, etc. In some embodiments, the sealant 20 surrounds the display area AA.

[0072] A plurality of metal protection lines 11 that are spaced apart from each other and insulated and disposed in the non-display area NA may be disposed on the same layer. Alternatively, a plurality of metal protection lines 11 that are spaced apart from each other and insulated and disposed in the non-display area NA may also be disposed on different layers.

[0073] In some embodiments, a plurality of metal protection lines 11 that are spaced apart from each other and insulated and are disposed in the non-display area NA are disposed on the same layer. The plurality of metal protection lines 11 that are spaced apart from each other and insulated and are disposed in the non-display area NA may belong to the first metal layer (the metal layer where the gate electrode and the gate scan line are located) or the second metal layer (the metal layer where the data line is located) of the array substrate 10. Specifically, after the first metal layer is deposited and formed, the first metal layer is etched through a mask. For example, wet etching (wet) is used for the etching to form a plurality of metal protection lines 11, a gate electrode, and a gate scan line that are spaced apart from each other and insulated. Alternatively, after the second metal layer is deposited and formed, the second metal layer is etched through a mask. For example, wet etching (wet) is used for the etching to form a plurality of metal protection lines 11 and a data line that are spaced apart from each other and insulated.

[0074] In some embodiments, a plurality of metal protection lines 11 that are spaced apart from each other and insulated and are disposed in the non-display area NA are disposed on different layers. A part of the plurality of metal protection lines 11 that are spaced apart from each other and insulated and are disposed in the non-display area NA belongs to the first metal layer of the array substrate 10, and another part belongs to the second metal layer of the array substrate 10. Specifically, after the first metal layer is deposited and formed, the first metal layer is etched through a mask to form a part of the metal protection lines 11, a gate electrode, and a gate scan line; after the second metal layer is deposited and formed, the second metal layer is etched through a mask to form another part of the metal protection lines 11 and a data line.

[0075] It should be noted that the fact that the plurality of metal protection lines 11 are located between the sealant 20 and the gate driving circuit 10a can be understood as that the orthographic projection of the plurality of metal protection lines 11 on the substrate of the array substrate 10 is located between the orthographic projection of the sealant 20 on the substrate of the array substrate 10 and the orthographic projection of the gate driving circuit 10a on the substrate of the array substrate 10.

[0076] In the embodiments of the present application, by disposing a plurality of metal protection lines 11 between the sealant 20 and the gate driving circuit 10a, the plurality of metal protection lines 11 are closer to the sealant 20 than the gate driving circuit 10a. In the case where corrosive liquid gas such as water vapor invades the space enclosed by the sealant 20 or there is residual corrosive liquid gas such as water vapor inside, the plurality of metal protection lines 11 contact and consume the corrosive liquid gas such as water vapor prior to the gate driving circuit 10a. By sacrificing the plurality of metal protection lines 11, the situation where the corrosive liquid gas such as water vapor diffuses to main functional components such as the gate driving circuit 10a is reduced, thereby reducing the situation where the main functional components of the display panel 100 are corroded and the display panel 100 fails, so as to achieve the protection effect on the display panel 100 and improve the service life of the display panel 100.

[0077] Compared with only setting a single metal protection line 11 between the sealant 20 and the gate driving circuit 10a, embodiments of the present application set multiple metal protection lines 11 between the sealant 20 and the gate driving circuit 10a, which has a better corrosion resistance effect on main functional components such as the gate driving circuit 10a.

[0078] Through the setting of multiple metal protection lines 11, embodiments of the present application do not need to improve main functional components such as the gate driving circuit 10a, are applicable to various display solutions in the industry, can follow the manufacturing process flows of various display solutions in the industry, do not require special transformation, and can reduce the corrosion of the gate driving circuit 10a by water vapor, etc. at a relatively low cost.

[0079] Please refer to Figures 2 to 4 , Figure 2 is Figure 1 the first structural schematic diagram of the array substrate of the display panel shown in Figure 3 is Figure 1 the second structural schematic diagram of the array substrate of the display panel shown in Figure 4 is Figure 1 the third structural schematic diagram of the array substrate of the display panel shown in

[0080] In some embodiments, multiple metal protection lines 11 all extend along the edge of the display area AA. Refer to Figure 2 , taking the number of metal protection lines 11 as two as an example, to illustrate the specific solution where multiple metal protection lines 11 all extend along the edge of the display area AA. Specifically, multiple metal protection lines 11 include a first metal line 111 and a second metal line 112, and the first metal line 111 is located between the second metal line 112 and the sealant 20. The second metal line 112 is located between the first metal line 111 and the gate driving circuit 10a.

[0081] Both the first metal line 111 and the second metal line 112 extend along the edge of the display area AA, and can surround part or the whole display area AA, which is beneficial to preferentially receiving corrosive liquid gas such as water vapor when corrosive liquid gas such as water vapor invades the space enclosed by the sealant 20 or there is residual corrosive liquid gas such as water vapor inside, and reacting with the corrosive liquid gas such as water vapor, thereby reducing the corrosion of the gate driving circuit 10a by water vapor, etc.

[0082] The second metal wire 112 is located between the first metal wire 111 and the frame glue 20, which is beneficial for the first metal wire 111 to preferentially receive the corrosive liquid and gas such as water vapor and react with the corrosive liquid and gas such as water vapor when the corrosive liquid and gas such as water vapor invades the space enclosed by the frame glue 20 or the corrosive liquid and gas such as water vapor remains inside. In this way, the possibility of the second metal wire 112 being corroded is reduced, so that the possibility of the first metal wire 111 and the second metal wire 112 being corroded is different and not synchronized, which is beneficial to delaying the time when the first metal wire 111 and the second metal wire 112 are completely corroded and fail, delaying the total effective time of the first metal wire 111 and the second metal wire 112, reducing the corrosion of the gate driving circuit 10a by water vapor, etc., and increasing the service life of the display panel 100.

[0083] In some embodiments, see Figure 2 The first metal wire 111 and the second metal wire 112 both extend along the edge of the display area AA and form a surrounding structure, which fully receives the corrosive liquid gas such as water vapor invading from the frame glue 20, thereby reducing the corrosion of the gate driving circuit 10a by the water vapor.

[0084] In some embodiments, see Figure 3 The first metal line 111 and the second metal line 112 both extend along the edge of the display area AA and form a semi-enclosed structure to reduce interference with the routing of the fan-out area of the array substrate 10 .

[0085] In some embodiments, see Figure 4 The first metal line 111 and the second metal line 112 both extend along the edge of the display area AA and are both composed of a plurality of extension portions that are spaced apart, so as to improve the flexibility of the arrangement of the first metal line 111 and the second metal line 112 .

[0086] It should be noted that Figures 2 to 4 The frame glue 20 in FIG. 1 is the positive projection of the frame glue 20 on the array substrate 10 .

[0087] It should be noted that, in some embodiments, in the scheme of the first metal wire 111 and the second metal wire 112 of the present application extending along the edge of the display area AA, the mentioned enclosing structure, semi-enclosing structure and the scheme consisting of multiple extension sections can all include a scheme in which part of the first metal wire 111 and / or part of the second metal wire 112 are connected through vias between different metal layers of the array substrate 10 to avoid some other routing components of the array substrate 10.

[0088] It should be noted that the first metal wire 111 and the second metal wire 112 may extend along the edge of the display area AA in the same or different manner, which is specifically configured according to actual conditions and will not be described in detail in this application.

[0089] See alsoFigure 5 and Figure 6 , Figure 5 FIG. Figure 5 is a schematic structural diagram of a display panel provided by a second embodiment of the present application. Figure 6 is Figure 5 a top view structural diagram of an array substrate of the display panel shown in FIG. Figure 5 in area A1.

[0090] In some embodiments, referring to Figures 1 to 6 , a plurality of metal protection lines 11 include a first metal line 111 and a second metal line 112. The first metal line 111 and the second metal line 112 are disposed in the same layer. The array substrate 10 further includes an insulating layer 12 covering the first metal line 111 and the second metal line 112. The insulating layer 12 has one or more through holes H, such that both the first metal line 111 and the second metal line 112 are partially exposed.

[0091] The first metal line 111 and the second metal line 112 being disposed in the same layer is beneficial to simplifying the manufacturing process of the display panel 100. The setting of the insulating layer 12 is beneficial to slowing down the occurrence of situations such as metal corrosion / oxidation failure caused by water washing / chemical liquid washing and other processes or long-term exposure to air after the manufacturing process of the metal protection line 11. In some embodiments, the insulating layer 12 is a whole-surface deposited film layer during the manufacturing process of the display panel 100, without the need to increase processes, simplifying the manufacturing process. The insulating layer 12 exposes both the first metal line 111 and the second metal line 112 through the through holes H thereon, enabling contact between corrosive liquid gases such as water vapor and the first metal line 111 and the second metal line 112. While delaying the corrosion rate of the first metal line 111 and the second metal line 112 by corrosive liquid gases such as water vapor, the first metal line 111 and the second metal line 112 preferentially consume corrosive liquid gases such as water vapor, reducing the corrosion of the gate driving circuit 10a by water vapor and the like.

[0092] The insulating layer 12 includes a first portion covering the side of the first metal line 111 away from the substrate and a second portion covering the side of the second metal line 112 away from the substrate. The first portion and the second portion of the insulating layer 12 may be spaced apart or connected together through other portions of the insulating layer 12.

[0093] The through hole H in the first part of the first metal line 111 covered by the insulating layer 12 on the side close to the frame adhesive 20 can be one or more. The through hole H in the second part of the second metal line 112 covered by the insulating layer 12 on the side close to the frame adhesive 20 can be one or more. The cross-sectional shape of the through hole H can be one or more. When there are multiple through holes H in the first part of the insulating layer 12, the cross-sectional shapes of the multiple through holes H can be the same, partially the same, or different from each other. When there are multiple through holes H in the second part of the insulating layer 12, the cross-sectional shapes of the multiple through holes H can be the same, partially the same, or different from each other. The cross-sectional shape of the through hole H in the first part of the insulating layer 12 and the cross-sectional shape of the through hole H in the second part can be the same, partially the same, or different from each other. For example, the cross-sectional shape of the through hole H can be circular, rectangular, hexagonal, etc., or an approximate shape of the above cross-sectional shapes. For example, the cross-sectional shape of the through hole H can be an approximately rectangular cross-sectional shape, that is, a shape obtained by replacing the four right angles of the rectangle with arcs. In some embodiments, the cross-sectional shape of the through hole H is circular, and the diameter of the circle is greater than or equal to the lower limit of the process capability and does not affect other structures. In some embodiments, the cross-sectional shape of the through hole H is rectangular, and the length / width of the rectangle is greater than or equal to the lower limit of the process capability and does not affect other structures.

[0094] Please refer to Figure 7 and Figure 8 , Figure 7 FIG. is a schematic structural diagram of a display panel provided by the third embodiment of the present application, Figure 8 is Figure 7 a top view structural diagram of the array substrate of the display panel shown in FIG. in the A2 area.

[0095] In some embodiments, referring to Figures 7 to 8 , the array substrate 10 further includes a first insulating layer 13 and a second insulating layer 14. The first insulating layer 13 covers one side of the first metal line 111. The second metal line 112 is disposed on the side of the first insulating layer 13 away from the first metal line 111. The second insulating layer 14 covers the side of the second metal line 112 away from the first insulating layer 13. And one or more through holes H are provided in both the first insulating layer 13 and the second insulating layer 14, so that both the first metal line 111 and the second metal line 112 are partially exposed.

[0096] In some embodiments, the first metal line 111 and the second metal line 112 are disposed on different layers, and the first insulating layer 13 and the second insulating layer 14 are also disposed on different layers.

[0097] In some embodiments, the orthographic projection portions of the first metal line 111 and the second metal line 112 on the substrate of the array substrate 10 partially or completely overlap. This arrangement is beneficial for reducing the occupied width of the first metal line 111 and the second metal line 112 on the array substrate 10, thereby facilitating the reduction of the occupied width of the non-display area NA of the array substrate 10, and thus conducive to reducing the border of the display panel 100 and increasing the screen-to-body ratio of the display panel 100.

[0098] It should be noted that other functional layers (not shown in the figure) can be provided on the side of the insulating layer 12 close to the sealant 20 of the array substrate 10 of the present application, or on the side of the first insulating layer 13 / second insulating layer 14 close to the sealant 20, and are specifically set according to needs.

[0099] Please refer to Figure 9 and Figure 10 , Figure 9 which is a schematic structural diagram of a display panel provided by the fourth embodiment of the present application. Figure 10 is Figure 9 a top view structural diagram of the array substrate of the display panel shown in the A3 area.

[0100] In some embodiments, referring to Figure 9 and Figure 10 , the array substrate 10 further includes a transparent conductive layer 15, and the transparent conductive layer 15 is filled in the through hole H.

[0101] In some embodiments, the transparent conductive layer 15 includes ITO (indium tin oxide) transparent conductive material. In some embodiments, the transparent conductive layer 15 is filled in a part of the through holes H among the multiple through holes H. In some embodiments, the transparent conductive layer 15 is filled in all of the through holes H among the multiple through holes H.

[0102] In some embodiments, the transparent conductive layer 15 is not filled in some or all of the through holes H.

[0103] By providing the transparent conductive layer 15 in the embodiments of the present application, the material corroded by corrosive liquid gases such as water vapor in the through hole H can be increased, so that the corrosive liquid gases such as water vapor first corrode the ITO transparent conductive material of the through hole H and then corrode the metal protection line 11, which is beneficial to consuming more corrosive liquid gases such as water vapor and improving the service life of the display panel 100.

[0104] Please refer to Figure 11 , Figure 11 which is a schematic structural diagram of a display panel provided by the fifth embodiment of the present application.

[0105] In this embodiment, there is a potential difference between at least two of the multiple metal protection lines 11, that is, the difference in the voltages of at least two of the multiple metal protection lines 11 is not zero. Specifically, takingFigure 11 Taking the display panel 100 shown as an example, the plurality of metal protection lines 11 include a first metal line 111 and a second metal line 112. Both the first metal line 111 and the second metal line 112 are connected to a voltage signal line so that a potential difference is formed between the first metal line 111 and the second metal line 112, thereby forming a sacrificial electrolytic cell structure, which consumes corrosive liquid gases such as water vapor invading from the outside (or remaining inside) prior to main functional components such as the gate driving circuit 10a, reducing the corrosion of the gate driving circuit 10a by water vapor and the like.

[0106] Please refer to Figure 12 , Figure 12 which is a schematic structural diagram of a display panel provided by the sixth embodiment of the present application.

[0107] In some embodiments, referring to Figure 12 , the plurality of metal protection lines 11 include a first metal line 111, a second metal line 112, and a third metal line 113. Along the direction gradually approaching the display area AA, the first metal line 111, the second metal line 112, and the third metal line 113 are sequentially arranged at intervals.

[0108] In some embodiments, the first metal line 111 is not powered. There is a potential difference between the second metal line 112 and the third metal line 113. The greater the potential difference, the easier the reaction. Therefore, in this case, the reaction occurs first between the second metal line 112 and the third metal line 113. Since the first metal line 111 is not powered, it does not need to be connected to an electrical signal line, and the first metal line 111 can be preferentially consumed when the display panel 100 is not powered (such as during transportation or storage), without worrying about the corrosion of the first metal line 111 being conducted to the second metal line 112, the third metal line 113, and other electrical signal lines. It can be understood that if the second metal line 112 and the third metal line 113 are corroded when the display panel 100 is not powered (such as during transportation or storage), it will affect the ability of the electrolytic cell formed during subsequent power-on to consume water vapor.

[0109] In some embodiments, the potentials of the first metal line 111 and the third metal line 113 are both higher than the potential of the second metal line 112, and the potentials of the first metal line 111 and the third metal line 113 are the same, so that the first metal line 111 and the second metal line 112 cooperate, and the third metal line 113 and the second metal line 112 cooperate to form two electrolytic cell structures, which can consume corrosive liquid gases such as water vapor simultaneously.

[0110] In some embodiments, the electric potentials of the first metal line 111 and the third metal line 113 are both higher than that of the second metal line 112, and the potential difference between the first metal line 111 and the second metal line 112 is greater than the potential difference between the third metal line 113 and the second metal line 112, so that the first metal line 111 is consumed before the third metal line 113. In some embodiments, the voltage of the second metal line 112 may be 0V.

[0111] In some embodiments, the electric potentials of the first metal line 111, the second metal line 112, and the third metal line 113 decrease in sequence, so that the first metal line 111, the second metal line 112, and the third metal line 113 are oxidized and consumed in sequence. In some embodiments, the third metal line may be 0V (i.e., grounded) to save electrical energy.

[0112] Please refer to Figures 13 to 15 , Figure 13 which is a schematic structural diagram of a display panel provided by the seventh embodiment of the present application, Figure 14 is Figure 13 a first top-down structural diagram of the array substrate of the display panel shown in the A4 area, Figure 15 is Figure 13 a second top-down structural diagram of the array substrate of the display panel shown in the A4 area.

[0113] In some embodiments, referring to Figure 13 and Figure 14 , a plurality of metal protection lines 11 include a first metal line 111 and a second metal line 112. The first metal line 111 is electrically connected to the common electrode line VCOM (refer to Figure 13 ) of the array substrate 10 or a cathode electrode line (not shown in the figure), and the second metal line 112 is electrically connected to the timing signal line CK of the array substrate 10, so that there is a potential difference between the first metal line 111 and the second metal line 112.

[0114] Among them, the array substrate 10 of the LCD display panel includes a common electrode line VCOM for electrically conducting with the common electrode of the color filter substrate through a gold ball. The array substrate 10 of the LED display panel or the OLED display panel includes a cathode electrode line for connecting to the cathode electrode layer 91 (refer to Figure 21 ).

[0115] In an embodiment of the present application, the common electrode line VCOM and the timing signal line CK of the array substrate 10 are electrically connected to the first metal line 111 and the second metal line 112 respectively. By using the original voltage signal lines of the array substrate 10, without changing the main functional components such as the gate driving circuit 10a, the effect of reducing the corrosion of the gate driving circuit 10a by water vapor and the like can be achieved. Thus, the solution for reducing the corrosion of the gate driving circuit 10a by water vapor and the like in the present application can follow the manufacturing process flows of various display solutions in the industry, without special modification, and can be applicable to various display solutions in the industry.

[0116] In some embodiments, referring to Figure 13 and Figure 14 , the first metal line 111 is electrically connected to the common electrode line VCOM (refer to Figure 14 ) or the cathode electrode line (not shown in the figure) of the array substrate 10 through the first corrosion-resistant wire 161, and the second metal line 112 is electrically connected to the timing signal line CK of the array substrate 10 through the second corrosion-resistant wire 162.

[0117] To prevent corrosion from being conducted from the first metal line 111 or the second metal line 112 to the common electrode line VCOM or the timing signal line CK, in an embodiment of the present application, the first corrosion-resistant wire 161 is used to connect the first metal line 111 and the common electrode line VCOM, and the second corrosion-resistant wire 162 is used to connect the second metal line 112 and the timing signal line CK, so as to reduce the corrosion of the gate driving circuit 10a by water vapor and the like and increase the service life of the display panel 100.

[0118] In some embodiments, the first corrosion-resistant wire 161 and / or the second corrosion-resistant wire 162 can be made of one or both of carbon nanotubes or inert metal wires. Exemplarily, the inert metal wire can include a gold wire.

[0119] In some embodiments, referring to Figure 15 , the first metal line 111 is electrically connected to the common electrode line VCOM (refer to Figure 15 ) or the cathode electrode line (not shown in the figure) of the array substrate 10 through the first TFT 171, and the second metal line 112 is electrically connected to the timing signal line CK of the array substrate 10 through the second TFT 172.

[0120] To prevent corrosion from spreading to the common electrode line VCOM or the timing signal line CK, embodiments of the present application connect the first metal line 111 to the common electrode line VCOM through the first TFT 171, and connect the second metal line 112 to the timing signal line CK through the second TFT 172. The first TFT 171 and the second TFT 172 can prevent corrosion from spreading from the first metal line 111 or the second metal line 112 to the common electrode line VCOM or the timing signal line CK, thereby reducing corrosion of the gate driving circuit 10a by moisture and the like, and increasing the service life of the display panel 100.

[0121] In some embodiments, the first TFT 171 and / or the second TFT 172 provided by embodiments of the present application can be fabricated together when fabricating the thin film transistors TFTs of the gate driving circuit 10a, which helps to reduce the manufacturing process.

[0122] Please refer to Figures 16 to 17 , Figure 16 which is a schematic structural diagram of a display panel provided by the eighth embodiment of the present application, Figure 17 which is a schematic structural diagram of a display panel provided by the ninth embodiment of the present application.

[0123] In some embodiments, referring to Figure 16 and Figure 17 , the display panel 100 further includes a control circuit assembly 30.

[0124] In some embodiments, the control circuit assembly 30 is configured to control the first TFT 171 and the second TFT 172 to turn on in response to the display panel 100 being powered on.

[0125] When the display panel 100 is not powered on, such as during transportation or storage, or when the power supply of the display panel 100 is not connected, the metal protection line 11 itself can still react with corrosive liquid or gas such as moisture, consume the corrosive liquid or gas such as moisture, and reduce the corrosion of the gate driving circuit 10a.

[0126] When the display panel 100 is powered on, turning on the first TFT 171 and the second TFT 172 can form an electrolytic cell structure between the two metal protection lines. Compared with the situation where the metal protection line 11 is not connected to the potential, it can make the metal protection line 11 react better with corrosive liquid or gas such as moisture, consume more corrosive liquid or gas such as moisture, thereby reducing the corrosion of the gate driving circuit 10a. Even when the display panel 100 is not working, keeping the display panel 100 powered on (for example, a TV is plugged in for a long time), in such a case, keeping the first TFT 171 and the second TFT 172 turned on is beneficial to consuming more corrosive liquid or gas such as moisture, thereby reducing the corrosion of the gate driving circuit 10a.

[0127] In some embodiments, the control circuit component 30 is configured to control the first TFT 171 and the second TFT 172 to be turned off in response to the display panel 100 being powered on but not working.

[0128] The display panel 100 not working means that the display panel 100 does not display an image. The display panel 100 working means that the display panel 100 displays an image.

[0129] When the display panel 100 is powered on and not working, the temperature of the display panel 100 is not high, and corrosive liquids and gases such as water vapor are not easily introduced and diffused. At this time, turning off the first TFT 171 and the second TFT 172 is beneficial to reducing power consumption.

[0130] In some embodiments, the control circuit component 30 is configured to control the first TFT 171 and the second TFT 172 to be turned on in response to the display panel 100 being powered on and working.

[0131] When the display panel 100 is powered on and working, the temperature of the display panel 100 is likely to increase, and corrosive liquids and gases such as water vapor are easily introduced and diffused. At this time, turning on the first TFT 171 and the second TFT 172 is beneficial to increasing the consumption of corrosive liquids and gases such as water vapor by the metal protection line 11 and reducing the corrosion of the gate driving circuit 10a.

[0132] In some embodiments, the control circuit component 30 is configured to control the first TFT 171 and the second TFT 172 to be turned on and apply a first potential difference between the two metal protection lines 11 in response to the display panel 100 being powered on but not working. In response to the display panel 100 being powered on and working, control the first TFT 171 and the second TFT 172 and apply a second potential difference between the two metal protection lines 11, where the second potential difference is greater than the first potential difference.

[0133] When the display panel 100 is powered on, whether the display panel 100 is working or not, a potential difference is applied between the two metal protection lines 11 to form an electrolytic cell structure. Compared with the solution of not applying a potential difference between the two metal protection lines 11, the consumption of corrosive liquids and gases such as water vapor by the metal protection line 11 is increased, and the corrosion of the gate driving circuit 10a by corrosive liquids and gases such as water vapor is reduced. Further, by making the second potential difference greater than the first potential difference, the consumption of corrosive liquids and gases such as water vapor by the metal protection line 11 when the display panel 100 is working is stronger than that when the display panel 100 is not working, improving the protection of the display panel 100.

[0134] In some embodiments, the second potential difference is greater than the potential difference between the signal lines (such as the CK line) of the gate driving circuit 10a, so that corrosive liquid gases such as water vapor are preferentially consumed in the electrolytic cell reaction formed by the plurality of metal protection lines 11 to reduce the corrosion of the gate driving circuit 10a.

[0135] In some embodiments, please continue to refer to Figure 16 , the control circuit assembly 30 includes a driving chip 31 and a circuit board 32. Among them, the driving chip 31 is electrically connected to the array substrate 10 through the circuit board 32. The plurality of metal protection lines 11 are all directly bonded to the circuit board 32 and electrically connected to the output end of the driving chip 31 through the circuit board 32.

[0136] The driving chip 31 receives control signals from the main board or other circuits and drives the display function of the display panel 100. In some embodiments, the circuit board 32 includes a printed circuit board 321 and a flexible circuit board 322. The driving chip 31 is disposed on the printed circuit board 321 and is electrically connected to the array substrate 10 through the flexible circuit board 322, so that the flexible circuit board 322 can rotate or turn relative to the array substrate 10 and be fixed on the array substrate 10. In some embodiments, the circuit board 32 can also access the array substrate 10 through a flip chip film, and then directly give signals to the metal protection lines 11. In addition, the detailed technical features of other hardware parts of the electronic device are within the scope of understanding in the art and will not be elaborated here.

[0137] In some embodiments, refer to Figure 16 , the driving chip 31 is electrically connected to the data line Data of the array substrate 10 through the circuit board 32. It can be understood that the driving chip 31 is also electrically connected to other signal lines of the array substrate 10 through the circuit board 32, such as the gate line Gate (refer to Figure 17 ).

[0138] By electrically connecting the control circuit assembly 30 with the plurality of metal protection lines 11 in the embodiments of the present application, and using the original control circuit assembly 30 of the display panel 100, without changing the main functional components such as the gate driving circuit 10a, the effect of reducing the corrosion of the gate driving circuit 10a by water vapor and the like can be achieved, so that the solution for reducing the corrosion of the gate driving circuit 10a by water vapor and the like in the present application can follow the manufacturing process flow of various display solutions in the industry without special modification and can be applicable to various display solutions in the industry.

[0139] In some embodiments, please continue to refer to Figure 17, both the first metal line 111 and the second metal line 112 are arranged on the same layer as the data line Data of the array substrate 10, and both the first metal line 111 and the second metal line 112 are in a closed loop structure. Both the first metal line 111 and the second metal line 112 are connected to the bonding electrode 40 through a via hole H' and are bonded to the circuit board 32 through the bonding electrode 40.

[0140] In the embodiment of the present application, since both the first metal line 111 and the second metal line 112 are arranged on the same layer as the data line Data of the array substrate 10, by using the original data line Data of the array substrate 10, the effect of reducing the corrosion of the gate driving circuit 10a by water vapor and the like can be achieved without changing the main functional components such as the gate driving circuit 10a. Thus, the solution for reducing the corrosion of the gate driving circuit by water vapor and the like in the present application can follow the manufacturing process flows of various display solutions in the industry without special modification and can be applicable to various display solutions in the industry.

[0141] In some embodiments, referring to Figure 17 , both the first metal line 111 and the second metal line 112 are arranged on the same layer as the gate line Gate of the array substrate 10.

[0142] In the embodiment of the present application, since both the first metal line 111 and the second metal line 112 are arranged on the same layer as the gate line Gate of the array substrate 10, by using the original gate line Gate of the array substrate 10, the effect of reducing the corrosion of the gate driving circuit 10a by water vapor and the like can be achieved without changing the main functional components such as the gate driving circuit 10a. Thus, the solution for reducing the corrosion of the gate driving circuit 10a by water vapor and the like in the present application can follow the manufacturing process flows of various display solutions in the industry without special modification and can be applicable to various display solutions in the industry.

[0143] Please refer to Figure 18 , Figure 18 is a schematic structural diagram of a display panel provided by the tenth embodiment of the present application.

[0144] In some embodiments, referring to Figure 18 , the display panel 100 further includes a humidity sensor 50.

[0145] In some embodiments, the control circuit assembly 30 is configured to not energize the metal protection line 11 in response to the humidity detected by the humidity sensor 50 being lower than a humidity threshold.

[0146] It can be understood that the humidity threshold can be set as needed. For example, empirical values or experimental values can be adopted.

[0147] When it is detected that the humidity is lower than the humidity threshold, the water vapor and other corrosive liquid gases entering and diffusing into the display panel 100 are less. Not energizing the metal protection line 11 is beneficial to reducing power consumption.

[0148] In some embodiments, the control circuit component 30 is configured to apply a potential difference between the two metal protection lines 11 in response to the humidity detected by the humidity sensor 50 being greater than or equal to the humidity threshold.

[0149] When it is detected that the humidity is greater than the humidity threshold, there is more corrosive liquid gas such as water vapor entering and diffusing into the display panel 100. Applying a potential difference between the two metal protection lines 11 forms an electrolytic cell structure, which is beneficial to increasing the consumption of corrosive liquid gas such as water vapor by the metal protection lines 11. For example, in an embodiment where the number of metal protection lines 11 is three, there is a potential difference between the two metal protection lines 11 close to the sealant 20, and one metal protection line 11 close to the gate driving circuit 10a is not powered. In this embodiment, the two metal protection lines 11 close to the sealant 20 form an electrolytic cell structure, which preferentially consumes corrosive liquid gas such as water vapor. The unpowered metal protection line 11 close to the gate driving circuit 10a can further consume the corrosive liquid gas such as water vapor that has not been completely reacted by the electrolytic cell reaction, thereby playing a role in protecting the gate driving circuit 10a and even the display panel 100.

[0150] In some embodiments, the humidity sensor 50 can be disposed outside the display panel 100 to detect the ambient humidity, or can be disposed inside the display panel 100 to detect the internal water vapor.

[0151] Please refer to Figures 19 to 21 , Figure 19 which is a schematic structural diagram of a display panel provided by the eleventh embodiment of the present application, Figure 20 which is a schematic structural diagram of a display panel provided by the twelfth embodiment of the present application, Figure 21 which is a schematic structural diagram of a display panel provided by the thirteenth embodiment of the present application.

The sealant 20 is disposed between the array substrate 10 and the counter substrate 60 and is located in the non-display area NA. The sealant 20 surrounds the gate driving circuit 10a. Among them, a plurality of metal protection lines 11 are located between the sealant 20 and the gate driving circuit 10a.

[0153] In some embodiments, the display panel 100 is an LED (light emitting diode) display panel. Referring to Figure 20, the LED display panel includes an array substrate 10, a cover plate 81, a light-emitting diode 82, a packaging resin 83, and a frame adhesive 20. The gate driving circuit 10a is disposed in the display area AA. The light-emitting diode 82 is disposed on one side of the gate driving circuit 10a, and the packaging resin 83 covers the light-emitting diode 82 and is located in the display area AA. The cover plate 81 is disposed on the side of the packaging resin 83 away from the array substrate 10. The frame adhesive 20 is disposed between the array substrate 10 and the cover plate 81 and is located in the non-display area NA. The frame adhesive 20 surrounds the gate driving circuit 10a. Among them, a plurality of metal protection lines 11 are located between the frame adhesive 20 and the gate driving circuit 10a.

[0154] In some embodiments, the display panel may be an OLED (organic electroluminescence) display panel. Refer to Figure 21 , the dam 21 of the OLED display panel serves the same function as the frame adhesive 20. The OLED display panel includes an array substrate 10, a cathode electrode layer 91, an organic light-emitting layer 92, an anode electrode layer 93, a packaging layer 94, and a dam 21. The gate driving circuit 10a is disposed in the display area AA. The anode electrode layer 93 is disposed on one side of the gate driving circuit 10a, the organic light-emitting layer 92 is disposed on the side of the anode electrode layer 93 away from the gate driving circuit 10a, the cathode electrode layer 91 is disposed on the side of the organic light-emitting layer 92 away from the gate driving circuit 10a, and the packaging layer 94 covers the cathode electrode layer 91, the metal protection lines 11, and the dam 21. The dam 21 is disposed between the array substrate 10 and the packaging layer 94 and is located in the non-display area NA. The dam 21 surrounds the gate driving circuit 10a. Among them, a plurality of metal protection lines 11 are located between the dam 21 and the gate driving circuit 10a.
