[0024] See also Figure 1 The embodiment of the present application provides a display panel 100, including a display area AA and a non-display area NA arranged outside the display area AA.

The number of metal protection lines 11 can be two, three, or other numbers, which can be set according to specific needs.

[0027] 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 panel 100 to emit light. Each GOA driving unit includes a plurality of thin film transistors (TFTs) and at least one capacitor.

[0028] In some embodiments, the display panel 100 is an LCD display panel, see Fig.19 The LCD display panel includes an array substrate 10, an opposing substrate 60, a liquid crystal layer 70 and a sealant 20.

[0029] In some embodiments, the substrate 60 is a color filter substrate for filtering light within a specific wavelength range to adjust the color displayed by the display panel 100 to achieve color display.

[0030] In some embodiments, the liquid crystal layer 70 includes liquid crystal molecules, a photoinitiator, and a polymerizable monomer that can undergo a polymerization reaction under ultraviolet light, wherein the liquid crystal molecules are nematic liquid crystal molecules having a negative dielectric anisotropy constant.

[0031] In some embodiments, the frame glue 20 has adhesiveness and may include one or more materials selected from acrylic frame glue, epoxy frame glue, polyurethane frame glue, and silicone frame glue. The frame glue 20 is disposed around the liquid crystal layer 70 and may simultaneously contact the two main surfaces of the array substrate 10 and the counter substrate 60 that are disposed opposite to each other, thereby bonding the array substrate 10 and the counter substrate 60 together through the adhesiveness of the frame glue 20, and at the same time, blocking external factors such as water vapor from entering the liquid crystal layer 70 to a certain extent, wherein the external factors include but are not limited to water vapor, dust impurities, etc.

[0032] In some embodiments, the display panel 100 is an LED (light emitting diode) display panel, see Fig. 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 glue 20. The gate drive circuit 10a is arranged in the display area AA. The light-emitting diode 82 is arranged on one side of the gate drive 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 arranged on the side of the packaging resin 83 away from the array substrate 10. The frame glue 20 is arranged between the array substrate 10 and the cover plate 81, and is located in the non-display area NA. The frame glue 20 is arranged around the gate drive circuit 10a. Among them, a plurality of metal protection lines 11 are located between the frame glue 20 and the gate drive circuit 10a.

[0033] In some embodiments, the display panel 100 may be an OLED (organic electroluminescent) display panel, see Fig.21 The dam 21 of the OLED display panel is equivalent to the role of the frame glue 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 drive circuit 10a is arranged in the display area AA. The anode electrode layer 93 is arranged on one side of the gate drive circuit 10a, the organic light-emitting layer 92 is arranged on the side of the anode electrode layer 93 away from the gate drive circuit 10a, the cathode electrode layer 91 is arranged on the side of the organic light-emitting layer 92 away from the gate drive circuit 10a, and the encapsulation layer 94 covers the cathode electrode layer 91, the metal protection line 11 and the dam 21. The dam 21 is arranged between the array substrate 10 and the encapsulation layer 94, and is located in the non-display area NA. The dam 21 is arranged around the gate drive circuit 10a. Among them, a plurality of metal protection lines 11 are located between the dam 21 and the gate drive circuit 10a.

[0034] The frame glue 20 blocks external factors such as water vapor from entering the display area AA of the array substrate 10 to a certain extent, wherein the external factors include but are not limited to water vapor, dust impurities, etc. In some embodiments, the frame glue 20 is disposed around the display area AA.

[0035] The plurality of metal protection lines 11 disposed in the non-display area NA and spaced apart from each other and insulated from each other may be disposed in the same layer, or may be disposed in different layers.

[0036] In some embodiments, a plurality of metal protection lines 11 spaced apart from each other and insulated from each other and arranged in the non-display area NA are arranged in the same layer. The plurality of metal protection lines 11 spaced apart from each other and insulated from each other and arranged 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 to form, the first metal layer is etched through a mask, for example, the etching adopts wet etching (wet), to form a plurality of metal protection lines 11 spaced apart from each other and insulated from each other, the gate electrode and the gate scan line. Alternatively, after the second metal layer is deposited to form, the second metal layer is etched through a mask, for example, the etching adopts wet etching (wet), to form a plurality of metal protection lines 11 spaced apart from each other and insulated from each other and the data line.

[0037] In some embodiments, the plurality of metal protection lines 11 spaced apart from each other and insulated from each other and disposed in the non-display area NA are disposed in different layers. A portion of the plurality of metal protection lines 11 spaced apart from each other and insulated from each other and disposed in the non-display area NA belongs to the first metal layer of the array substrate 10, and another portion belongs to the second metal layer of the array substrate 10. Specifically, after the first metal layer is deposited to form, the first metal layer is etched through a mask to form a portion of the metal protection line 11, the gate electrode, and the gate scanning line; after the second metal layer is deposited to form, the second metal layer is etched through a mask to form another portion of the metal protection line 11 and the data line.

[0038] It should be noted that the multiple metal protection lines 11 located between the frame glue 20 and the gate driving circuit 10a can be understood as the orthographic projection of the multiple metal protection lines 11 on the substrate of the array substrate 10 is located between the orthographic projection of the frame glue 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.

[0039] In the embodiment of the present application, a plurality of metal protection lines 11 are arranged between the frame glue 20 and the gate driving circuit 10a, so that the plurality of metal protection lines 11 are closer to the frame glue 20 than the gate driving circuit 10a. When corrosive liquids and gases such as water vapor invade the space enclosed by the frame glue 20 or when corrosive liquids and gases such as water vapor remain inside, the plurality of metal protection lines 11 contact and consume the corrosive liquids and gases such as water vapor before the gate driving circuit 10a. By sacrificing the plurality of metal protection lines 11, the diffusion of corrosive liquids and gases such as water vapor to main functional components such as the gate driving circuit 10a is reduced, thereby reducing the corrosion of the main functional components of the display panel 100 and causing the display panel 100 to fail, thereby achieving the protection of the display panel 100 and improving the service life of the display panel 100.

[0040] Compared with only setting a single metal protection line 11 between the frame glue 20 and the gate driving circuit 10a, the embodiment of the present application sets multiple metal protection lines 11 between the frame glue 20 and the gate driving circuit 10a, which has better corrosion resistance for main functional components such as the gate driving circuit 10a.

[0041] The embodiment of the present application, through the provision of multiple metal protection lines 11, does not require improvement of main functional components such as the gate drive circuit 10a, is applicable to various display solutions in the industry, and can follow the manufacturing process flow of various display solutions in the industry without special modification. It can reduce the corrosion of water vapor and the like to the gate drive circuit 10a at a relatively low cost.

[0042] See also Figure 2~Figure 4 , Figure 2 yes Figure 1 The first structural diagram of the array substrate of the display panel shown in FIG. Figure 3 yes Figure 1 A second structural diagram of an array substrate of a display panel is shown, Figure 4 yes Figure 1 A third structural schematic diagram of an array substrate of a display panel is shown.

[0043] In some embodiments, the plurality of metal protection lines 11 extend along the edge of the display area AA. Figure 2 , taking the number of metal protection lines 11 as two as an example, a specific solution in which multiple metal protection lines 11 extend along the edge of the display area AA is described. Specifically, the 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 frame glue 20. The second metal line 112 is located between the first metal line 111 and the gate driving circuit 10a.

[0044] The first metal wire 111 and the second metal wire 112 both extend along the edge of the display area AA and can surround part or the entire display area AA, which is beneficial for preferentially receiving the corrosive liquids and gases such as water vapor and reacting with the corrosive liquids and gases such as water vapor when the corrosive liquids and gases such as water vapor invade the space enclosed by the frame glue 20 or when there is residual corrosive liquids and gases such as water vapor inside, thereby reducing the corrosion of the gate driving circuit 10a by water vapor and the like.

[0045] 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.

[0046] 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.

[0047] 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 .

[0048] 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 .

[0049] It should be noted that Figure 2~Figure 4 The frame glue 20 in FIG. 1 is the positive projection of the frame glue 20 on the array substrate 10 .

[0050] 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.

[0051] 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.

[0052] See also Figure 5 and Figure 6 , Figure 5 is a schematic diagram of the structure of a display panel provided in the second embodiment of the present application, Figure 6 yes Figure 5 The shown schematic diagram is a top view of the structure of the array substrate of the display panel in the A1 area.

[0053] In some embodiments, see Figure 1 to Figure 6 The 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, so that the first metal line 111 and the second metal line 112 are partially exposed.

[0054] The first metal wire 111 and the second metal wire 112 are arranged in the same layer, which is conducive to simplifying the preparation process of the display panel 100. The setting of the insulating layer 12 is conducive to slowing down the occurrence of metal corrosion / oxidation failure caused by water washing / chemical washing and other processes after the metal protection wire 11 process or long-term exposure to the air. In some embodiments, the insulating layer 12 is a whole-surface deposited film layer in the production process of the display panel 100, without adding any process, simplifying the preparation process. The insulating layer 12 partially exposes the first metal wire 111 and the second metal wire 112 through the through hole H thereon, so that corrosive liquids and gases such as water vapor are in contact with the first metal wire 111 and the second metal wire 112, and the first metal wire 111 and the second metal wire 112 are preferentially consumed by corrosive liquids and gases such as water vapor, while slowing down the rate at which the first metal wire 111 and the second metal wire 112 are corroded by corrosive liquids and gases such as water vapor, thereby reducing the corrosion of the gate drive circuit 10a by water vapor.

[0055] The insulating layer 12 includes a first portion covering the first metal line 111 on a side away from the substrate and a second portion covering the second metal line 112 on a side 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 .

[0056] The insulating layer 12 may cover one or more through holes H on the first part of the first metal wire 111 near the sealant 20. The insulating layer 12 may cover one or more through holes H on the second part of the second metal wire 112 near the sealant 20. The cross-sectional shape of the through hole H may be one or more. In the case where there are multiple through holes H on the first part of the insulating layer 12, the cross-sectional shapes of the multiple through holes H may be the same, partially the same, or different. In the case where there are multiple through holes H on the second part of the insulating layer 12, the cross-sectional shapes of the multiple through holes H may be the same, partially the same, or different. The cross-sectional shape of the through hole H on the first part of the insulating layer 12 may be the same, partially the same, or different from the cross-sectional shape of the through hole H on the second part. For example, the cross-sectional shape of the through hole H may be circular, rectangular, hexagonal, etc., or may be an approximate shape of the above cross-sectional shapes, for example, the cross-sectional shape of the through hole H may be an approximate rectangular cross-sectional shape, that is, a figure in which the four right angles of the rectangle are replaced by arcs. In some embodiments, the cross-sectional shape of the through hole H is a circle, 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 a rectangle, 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.

[0058] In some embodiments, see Figure 7~Figure 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 a side of the first insulating layer 13 away from the first metal line 111. The second insulating layer 14 covers a side of the second metal line 112 away from the first insulating layer 13. The first insulating layer 13 and the second insulating layer 14 are both provided with one or more through holes H, so that the first metal line 111 and the second metal line 112 are partially exposed.

[0059] In some embodiments, the first metal line 111 and the second metal line 112 are disposed in different layers, and the first insulating layer 13 and the second insulating layer 14 are also disposed in different layers.

[0060] In some embodiments, the orthographic projections 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 to reducing the width occupied by the first metal line 111 and the second metal line 112 on the array substrate 10, thereby helping to reduce the width occupied by the non-display area NA of the array substrate 10, thereby helping to reduce the border of the display panel 100 and improve the screen-to-body ratio of the display panel 100.

[0061] It should be noted that the array substrate 10 of the present application may be provided with other functional layers (not shown) on the side of the insulating layer 12 close to the sealant 20 or on the side of the first insulating layer 13 / second insulating layer 14 close to the sealant 20 , and the specific configuration is based on needs.

[0062] See also Fig. 9 and Fig.10 , Fig. 9 is a schematic structural diagram of a display panel provided in a fourth embodiment of the present application, Fig.10 yes Fig. 9 The shown schematic diagram is a top view of the structure of the array substrate of the display panel in the A3 area.

[0063] In some embodiments, see Fig. 9 and Fig.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.

[0064] In some embodiments, the transparent conductive layer 15 includes an ITO (indium tin oxide) transparent conductive material. In some embodiments, the transparent conductive layer 15 fills a portion of the through holes H among the plurality of through holes H. In some embodiments, the transparent conductive layer 15 fills all of the through holes H among the plurality of through holes H.

[0065] In some embodiments, part or all of the through holes H are not filled with the transparent conductive layer 15 .

[0066] The embodiment of the present application can increase the material in the through hole H that is corroded by corrosive liquids and gases such as water vapor by setting the transparent conductive layer 15, so that the corrosive liquids and 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 conducive to consuming more corrosive liquids and gases such as water vapor and improving the service life of the display panel 100.

[0067] See also Fig.11 , Fig.11 It is a schematic diagram of the structure of a display panel provided in the fifth embodiment of the present application.

[0068] In this embodiment, there is a potential difference between at least two metal protection lines 11 of the plurality of metal protection lines 11, that is, the voltage difference between at least two metal protection lines 11 of the plurality of metal protection lines 11 is not zero. Fig.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. The first metal line 111 and the second metal line 112 are both 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 liquids and gases such as water vapor that invade from the outside (or remain inside) before main functional components such as the gate drive circuit 10a, thereby reducing the corrosion of the gate drive circuit 10a by water vapor.

[0069] See also Fig.12 , Fig.12 It is a schematic diagram of the structure of a display panel provided in the sixth embodiment of the present application.

[0070] In some embodiments, see Fig.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. The first metal line 111, the second metal line 112 and the third metal line 113 are sequentially arranged in a spaced relationship in a direction gradually approaching the display area AA.

[0071] In some embodiments, the first metal wire 111 is not powered. There is a potential difference between the second metal wire 112 and the third metal wire 113. The greater the potential difference, the easier it is to react, so in this case, the second metal wire 112 and the third metal wire 113 react first. The first metal wire 111 is not powered, so there is no need to connect the electrical signal line. The first metal wire 111 can be consumed preferentially when the display panel 100 is not powered (for example, during transportation or storage), and there is no need to worry about the corrosion of the first metal wire 111 being transmitted to the second metal wire 112 and the third metal wire 113 and other electrical signal lines. It can be understood that if the second metal wire 112 and the third metal wire 113 are corroded when the display panel 100 is not powered (for example, during transportation or storage), it will affect the ability of the electrolytic cell formed when the power is subsequently turned on to consume water vapor.

[0072] In some embodiments, the electric potential of the first metal wire 111 and the third metal wire 113 are both higher than the electric potential of the second metal wire 112, and the electric potential of the first metal wire 111 and the third metal wire 113 are the same, so that the first metal wire 111 and the second metal wire 112 cooperate, and the third metal wire 113 and the second metal wire 112 cooperate to form two electrolytic cell structures, which can simultaneously consume corrosive liquids and gases such as water vapor.

[0073] 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 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 can be 0V.

[0074] In some embodiments, the potentials of the first metal line 111, the second metal line 112 and the third metal line 113 are sequentially reduced 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 can be 0V (ie, grounded) to save power.

[0075] See also Figure 13~Figure 15 , Fig.13 is a schematic structural diagram of a display panel provided in the seventh embodiment of the present application, Fig.14 yes Fig.13 The first top view structural diagram of the array substrate of the display panel in the A4 area is shown, Fig.15 yes Fig.13 The array substrate of the display panel is shown as a second top view structural schematic diagram in the A4 area.

[0076] In some embodiments, see Fig.13 and Fig.14The plurality of metal protection lines 11 include a first metal line 111 and a second metal line 112. The first metal line 111 is connected to the common electrode line VCOM of the array substrate 10 (see Fig.13 ) or a cathode electrode line (not shown), 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.

[0077] The array substrate 10 of the LCD display panel includes a common electrode line VCOM, which is used to electrically connect to the common electrode of the color filter substrate through the gold ball. The array substrate 10 of the LED display panel or the OLED display panel includes a cathode electrode line, which is used to connect the cathode electrode layer 91 (see Fig.21 ).

[0078] The embodiment of the present application electrically connects the common electrode line VCOM and the timing signal line CK of the array substrate 10 to the first metal line 111 and the second metal line 112 respectively, and utilizes the original voltage signal line of the array substrate 10. It is not necessary to change the main functional components such as the gate drive circuit 10a, and the effect of reducing the corrosion of the gate drive circuit 10a caused by water vapor and the like can be achieved. Therefore, the solution of the present application for reducing the corrosion of the gate drive circuit 10a caused by water vapor and the like can follow the manufacturing process flow of various display solutions in the industry, without the need for special modification, and can be applicable to various display solutions in the industry.

[0079] In some embodiments, see Fig.13 and Fig.14 The first metal wire 111 is connected to the common electrode line VCOM of the array substrate 10 through the first corrosion-resistant wire 161 (see Fig.14 ) or a cathode electrode line (not shown), 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.

[0080] In order to prevent corrosion from being transmitted from the first metal wire 111 or the second metal wire 112 to the common electrode line VCOM or the timing signal line CK, the embodiment of the present application connects the first metal wire 111 and the common electrode line VCOM through a first corrosion-resistant wire 161, and connects the second metal wire 112 and the timing signal line CK through a second corrosion-resistant wire 162, so as to reduce the corrosion of the gate driving circuit 10a by water vapor and the like, thereby increasing the service life of the display panel 100.

[0081] In some embodiments, the first corrosion-resistant wire 161 and / or the second corrosion-resistant wire 162 may be made of one or both of carbon nanotubes and inert metal wires. For example, the inert metal wire may include a gold wire.

[0082] In some embodiments, see Fig.15The first metal line 111 is connected to the common electrode line VCOM of the array substrate 10 through the first TFT 171 (see Fig.15 ) or a cathode electrode line (not shown), and the second metal line 112 is electrically connected to the timing signal line CK of the array substrate 10 through the second TFT172.

[0083] In order to prevent corrosion from being transmitted to the common electrode line VCOM or the timing signal line CK, the embodiment of the present application connects the first metal line 111 and the common electrode line VCOM through the first TFT171, and connects the second metal line 112 and the timing signal line CK through the second TFT172. The first TFT171 and the second TFT172 can prevent corrosion from being transmitted from the first metal line 111 or the second metal line 112 to the common electrode line VCOM or the timing signal line CK, so as to reduce the corrosion of the gate drive circuit 10a by water vapor and the like, and increase the service life of the display panel 100.

[0084] In some embodiments, the first TFT 171 and / or the second TFT 172 provided in the embodiments of the present application may be manufactured together when the thin film transistor TFT of the gate driving circuit 10 a is manufactured, which is helpful to reduce the manufacturing process.

[0085] See also Figure 16-17 , Fig.16 is a schematic structural diagram of a display panel provided in an eighth embodiment of the present application, Fig.17 It is a schematic diagram of the structure of a display panel provided in the ninth embodiment of the present application.

[0086] In some embodiments, see Fig.16 and Fig.17 , the display panel 100 further includes a control circuit component 30 .

[0087] In some embodiments, the control circuit assembly 30 is used to control the first TFT 171 and the second TFT 172 to turn on in response to the display panel 100 being powered on.

[0088] When the display panel 100 is not powered, such as during transportation or storage, or when the power of the display panel 100 is not connected, the metal protection line 11 itself can still react with corrosive liquids and gases such as water vapor, consume the water vapor and other corrosive liquids and gases, and reduce corrosion to the gate drive circuit 10a.

[0089] When the display panel 100 is powered on, the first TFT 171 and the second TFT 172 are turned on, so that an electrolytic cell structure can be formed between the two metal protection lines. Compared with the case where the metal protection line 11 is not connected to the potential, the metal protection line 11 can react better with corrosive liquids and gases such as water vapor, consume more corrosive liquids and gases such as water vapor, and thus reduce the corrosion to the gate drive circuit 10a. Even when the display panel 100 is not working, the display panel 100 is kept powered on (for example, the TV is plugged in for a long time). In this case, keeping the first TFT 171 and the second TFT 172 turned on is conducive to consuming more corrosive liquids and gases such as water vapor, thereby reducing the corrosion to the gate drive circuit 10a.

[0090] In some embodiments, the control circuit assembly 30 is used 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.

[0091] The display panel 100 not working means that the display panel 100 does not display a picture. The display panel 100 working means that the display panel 100 displays a picture.

[0092] 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 easy to enter and diffuse. At this time, disconnecting the first TFT 171 and the second TFT 172 is beneficial to reducing power loss.

[0093] In some embodiments, the control circuit assembly 30 is used to control the first TFT 171 and the second TFT 172 to turn on in response to the display panel 100 being powered on and operating.

[0094] When the display panel 100 is powered on and working, the temperature of the display panel 100 is likely to rise, and corrosive liquids and gases such as water vapor are likely to enter and diffuse. At this time, opening the first TFT 171 and the second TFT 172 is beneficial to increase the consumption of corrosive liquids and gases such as water vapor by the metal protection line 11, and reduce corrosion to the gate drive circuit 10a.

[0095] In some embodiments, the control circuit assembly 30 is used to control the first TFT 171 and the second TFT 172 to turn 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, the first TFT 171 and the second TFT 172 are controlled to apply a second potential difference between the two metal protection lines 11, and the second potential difference is greater than the first potential difference.

[0096] 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 lines 11 is increased, and the corrosion of the gate driving circuit 10a by the corrosive liquids and gases such as water vapor is reduced. Furthermore, 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 lines 11 when the display panel 100 is working is stronger than the consumption of corrosive liquids and gases such as water vapor by the metal protection lines 11 when the display panel 100 is not working, thereby improving the protection of the display panel 100.

[0097] In some embodiments, the second potential difference is greater than the potential difference between signal lines (such as CK lines) of the gate driving circuit 10a, so that corrosive liquids and gases such as water vapor are preferentially consumed in the electrolytic cell reaction formed by multiple metal protection lines 11 to reduce corrosion to the gate driving circuit 10a.

[0098] In some embodiments, please see Fig.16 The control circuit assembly 30 includes a driving chip 31 and a circuit board 32. 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 directly bound and connected to the circuit board 32 and are electrically connected to the output end of the driving chip 31 through the circuit board 32.

[0099] The driver chip 31 receives control signals from the mainboard or other circuits to drive 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 driver chip 31 is arranged 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 be connected to the array substrate 10 through the chip-on-film, and then the signal is directly given to the metal protection line 11. In addition, the detailed technical features of the structure of other hardware parts of the electronic device are within the scope of understanding in this field and will not be repeated here.

[0100] In some embodiments, see Fig.16 The driver chip 31 is electrically connected to the data line Data of the array substrate 10 through the circuit board 32. It is understandable that the driver 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 (see Fig.17 ).

[0101] The embodiment of the present application electrically connects the control circuit component 30 with the multiple metal protection lines 11, and utilizes the original control circuit component 30 of the display panel 100. It is not necessary to change the main functional components such as the gate drive circuit 10a, so as to achieve the effect of reducing the corrosion of the gate drive circuit 10a caused by water vapor, etc., so that the solution of the present application for reducing the corrosion of the gate drive circuit 10a caused by water vapor, etc. can follow the manufacturing process flow of various display solutions in the industry, without the need for special modification, and can be applicable to various display solutions in the industry.

[0102] In some embodiments, please see Fig.17 The first metal wire 111 and the second metal wire 112 are both arranged in the same layer as the data wire Data of the array substrate 10, and both of the first metal wire 111 and the second metal wire 112 are in a closed ring structure. The first metal wire 111 and the second metal wire 112 are both connected to the binding electrode 40 through the via H', and are bound to the circuit board 32 through the binding electrode 40.

[0103] In the embodiment of the present application, the first metal wire 111 and the second metal wire 112 are arranged in the same layer as the data line Data of the array substrate 10. The original data line Data of the array substrate 10 is utilized 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. Therefore, the solution of the present application for reducing the corrosion of the gate driving circuit by water vapor and the like 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.

[0104] In some embodiments, see Fig.17 The first metal line 111 and the second metal line 112 are both arranged in the same layer as the gate line Gate of the array substrate 10 .

[0105] In the embodiment of the present application, the first metal wire 111 and the second metal wire 112 are arranged in the same layer as the gate line Gate of the array substrate 10. The original gate line Gate of the array substrate 10 is utilized 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. Therefore, the solution of the present application for reducing the corrosion of the gate driving circuit 10a by water vapor and the like 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.

[0106] See also Fig.18 , Fig.18 It is a schematic diagram of the structure of a display panel provided in the tenth embodiment of the present application.

[0107] In some embodiments, see Fig.18 , the display panel 100 further includes a humidity sensor 50 .

[0108] In some embodiments, the control circuit assembly 30 is configured to not supply power to the metal protection line 11 in response to the humidity detected by the humidity sensor 50 being lower than a humidity threshold.

[0109] It is understandable that the humidity threshold value can be set as needed, for example, an empirical value or an experimental value can be used.

[0110] When it is detected that the humidity is lower than the humidity threshold, less corrosive liquid gas such as water vapor enters and diffuses into the display panel 100, and the metal protection line 11 is not energized, which is beneficial to reduce power loss.

[0111] In some embodiments, the control circuit component 30 is used 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 a humidity threshold.

[0112] When it is detected that the humidity is greater than the humidity threshold, more corrosive liquids and gases such as water vapor enter and diffuse into the display panel 100, and a potential difference is applied between the two metal protection lines 11 to form an electrolytic cell structure, which is beneficial to improve the consumption of corrosive liquids and gases such as water vapor by the metal protection lines 11. For example, in an embodiment in which the number of metal protection lines 11 is three, there is a potential difference between two metal protection lines 11 close to the frame glue 20, and one metal protection line 11 close to the gate drive circuit 10a is not powered, the two metal protection lines 11 close to the frame glue 20 form an electrolytic cell structure, which preferentially consumes corrosive liquids and gases such as water vapor. The metal protection line 11 close to the gate drive circuit 10a that is not powered can further consume corrosive liquids and gases such as water vapor that have not been reacted by the electrolytic cell, thereby protecting the gate drive circuit 10a and even the display panel 100.

[0113] In some embodiments, the humidity sensor 50 may be disposed outside the display panel 100 to detect ambient humidity, or may be disposed inside the display panel 100 to detect internal water vapor.

The light-emitting diode 82 is arranged on one side of the gate drive 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 arranged on the side of the packaging resin 83 away from the array substrate 10. The frame glue 20 is arranged between the array substrate 10 and the cover plate 81, and is located in the non-display area NA. The frame glue 20 is arranged around the gate drive circuit 10a. Among them, a plurality of metal protection lines 11 are located between the frame glue 20 and the gate drive circuit 10a.

[0117] In some embodiments, the display panel may be an OLED (organic electroluminescent) display panel, see Fig.21 The dam 21 of the OLED display panel is equivalent to the role of the frame glue 20.

The dam 21 is arranged between the array substrate 10 and the encapsulation layer 94, and is located in the non-display area NA. The dam 21 is arranged around the gate drive circuit 10a. Among them, a plurality of metal protection lines 11 are located between the dam 21 and the gate drive circuit 10a.
