[0040] In order to further illustrate the display panel and display device provided by the embodiments of the present invention, a detailed description is given below with reference to the accompanying drawings.

[0041] See also Figure 1 and Figure 2 The present invention provides a display panel comprising: an array substrate and an opposing substrate 20 disposed opposite to each other; the array substrate comprising a sealing region 11, a first region 12, and a binding region 13, wherein the first region 12 is located between the sealing region 11 and the binding region 13, and the opposing substrate 20 is bonded to the array substrate in the sealing region 11 via a sealing adhesive layer 110; the array substrate further comprising:

[0042] a protective adhesive layer 30 , wherein the protective adhesive layer 30 at least partially covers the first area 12 ;

[0043] a functional film layer 40 , at least a portion of which is located between the protective adhesive layer 30 and the base substrate of the display panel;

[0044] The barrier layer 50 is at least partially located between the protective adhesive layer 30 and the functional film layer 40 . The density of the barrier layer 50 is higher than that of the functional film layer 40 .

[0045] Exemplarily, the display panel includes a liquid crystal display panel and an organic light emitting diode display panel, but is not limited thereto. In the liquid crystal display panel, the array substrate includes an array-distributed circuit structure, the opposing substrate 20 includes a color filter substrate, and a liquid crystal layer is provided between the array substrate and the color filter substrate. In the organic light emitting diode display panel, the array substrate includes array-distributed sub-pixels, each sub-pixel includes a coupled sub-pixel driving circuit and a light emitting element, the sub-pixel driving circuit is used to drive the light emitting element to emit light, thereby realizing the display function of the display panel; the specific structure of the sub-pixel driving circuit is varied, for example: adopting a 3T1C (3 transistors and 1 capacitor) circuit structure, but is not limited thereto; in the organic light emitting diode display panel, the opposing substrate 20 may include a color filter substrate, or may include a simple cover plate. In the organic light emitting diode display panel, a color filter layer may also be made on the array substrate, but is not limited thereto.

[0046] Exemplarily, the array substrate includes a sealing region 11, a first region 12, and a binding region 13. The array substrate also includes a display region. The sealing region 11 surrounds the display region. In the sealing region 11, the opposing substrate 20 is bonded to the array substrate via a sealing adhesive layer 110. The first region 12 and the binding region 13 are both located on one side of the sealing region 11, but are not limited thereto.

[0047] A protective adhesive layer 30 completely covers the first region 12. Exemplarily, the protective adhesive layer 30 comprises, but is not limited to, UV adhesive. Because the protective adhesive layer 30 is fluid during the manufacturing process, the resulting protective adhesive layer 30 will at least partially fill the space between the edge of the opposing substrate 20 and the array substrate.

[0048] Exemplarily, the functional film layer 40 includes a passivation layer, but is not limited thereto. The functional film layer 40 can extend to the binding area 13, the sealing area 11 and the display area.

[0049] Illustratively, the density of the barrier layer 50 is higher than that of the functional film layer 40 , that is, it is more difficult for water vapor to pass through the barrier layer 50 than it is for water vapor to pass through the functional film layer 40 .

[0050] According to the specific structure of the above-mentioned display panel, it can be known that in the display panel provided by the embodiment of the present invention, a barrier layer 50 with higher density is arranged between the protective adhesive layer 30 and the functional film layer 40. The barrier layer 50 more effectively blocks water vapor from invading the functional film layer 40, thereby increasing the peripheral waterproof capability, thereby preventing water vapor from spreading along the functional film layer 40 to the binding area 13, and preventing water vapor from affecting the display function of the display product.

[0051] Furthermore, for medium and large-sized display panels, when the resolution of the display panel is high, introducing the barrier layer 50 into the display panel can more effectively block water vapor from invading the functional film layer 40, thereby preventing water vapor from spreading along the functional film layer 40 to the binding area 13, and preventing water vapor from affecting the display function of the display product.

[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the barrier layer 50 includes at least one barrier pattern 501, and the barrier pattern 501 includes a first barrier portion 501a and a second barrier portion 501b. The first barrier portion 501a is located on the surface of the functional film layer 40 facing away from the base substrate and extends in a direction parallel to the base substrate. The second barrier portion 501b extends in a direction perpendicular to the base substrate. At least a portion of the second barrier portion 501b is located in a groove formed on the functional film layer 40, and the depth of the groove is less than or equal to the thickness of the functional film layer 40.

[0053] Exemplarily, the first blocking portion 501a and the second blocking portion 501b are formed into an integral structure, but the present invention is not limited thereto.

[0054] Exemplarily, a groove is formed on the functional film layer 40 by using a VIA mask, and the depth of the groove is less than or equal to the thickness of the functional film layer 40 .

[0055] For example, Figure 5 and Figure 6 As shown, a schematic diagram of the boundary of the groove GC is shown. Figure 5 The groove GC formed in the embodiment is a whole groove GC extending along the first direction. Figure 6 The groove GC formed in the embodiment is a small-sized groove GC corresponding to the blocking pattern 501 , and the orthographic projection of the small-sized groove GC on the base substrate is covered by the orthographic projection of the blocking pattern 501 on the base substrate.

[0056] Exemplarily, along the first direction, the width of the orthographic projection of the first blocking portion 501a on the substrate is greater than or equal to the width of the orthographic projection of the second blocking portion 501b on the substrate. Exemplarily, along the second direction, the width of the orthographic projection of the first blocking portion 501a on the substrate is greater than the width of the orthographic projection of the second blocking portion 501b on the substrate. Exemplarily, the first direction intersects the second direction, and the binding area 13, the first area 12, and the sealing area 11 are arranged along the second direction.

[0057] The first barrier portion 501a is located on the surface of the functional film layer 40 facing away from the base substrate and extends parallel to the base substrate. This effectively blocks moisture from entering the functional film layer 40 from the side where the protective adhesive layer 30 is located, thereby enhancing the peripheral waterproofing capability. Furthermore, by extending the second barrier portion 501b perpendicular to the base substrate and at least partially located within the groove formed in the functional film layer 40, the second barrier portion 501b effectively blocks moisture from traveling along the functional film layer 40 to the binding area 13, preventing moisture from affecting the display function of the display product.

[0058] like Figures 1 to 4 As shown, in some embodiments, the array substrate further includes:

[0059] a plurality of binding pins 60 arranged along a first direction, wherein the plurality of binding pins 60 are located in the binding area 13;

[0060] The barrier layer 50 includes at least one barrier pattern group 50z. The barrier pattern group 50z includes a plurality of barrier patterns 501 sequentially arranged along the first direction. There is a spacing area Q1 between adjacent barrier patterns 501.

[0061] Exemplarily, the multiple binding pins 60 include multiple power signal pins, multiple data signal pins, multiple sensing signal pins, etc.; the power signal pins are used to transmit power signals; the data signal pins are used to transmit corresponding data signals, which may include data signals provided to red sub-pixels, data signals provided to green sub-pixels, data signals provided to blue sub-pixels, and data signals provided to white sub-pixels; the sensing signal pins are used to transmit sensing signals.

[0062] The above-mentioned setting of the blocking pattern group 50z includes a plurality of the blocking patterns 501 arranged in sequence along the first direction, and there is a spacing area Q1 between adjacent blocking patterns 501, so that the length of the orthographic projection of the blocking pattern 501 on the base substrate along the first direction is small, thereby effectively avoiding the ESD (electrostatic discharge) problem caused by the blocking pattern 501.

[0063] In some embodiments, a width d of an orthographic projection of the blocking pattern 501 on the base substrate along the first direction satisfies: d≤0.05 mm.

[0064] It should be noted that generally, metal wires that are too long are prone to ESD problems. The lead length of conventional designs needs to be less than 60mm, and when the lead is floating, the length should be as less than 1mm as possible.

[0065] The above setting of d≤0.05 mm can reduce the ESD risk generated by the blocking pattern 501 to a very low level, thereby ensuring the reliability of the display panel.

[0066] like Figures 1 to 4 As shown, in some embodiments, the array substrate includes a plurality of signal transmission lines 70, the signal transmission lines 70 extending along a second direction, the second direction intersecting the first direction, and the signal transmission lines 70 coupled to corresponding binding pins 60;

[0067] The orthographic projection of the spacer area Q1 on the base substrate at least partially overlaps with the orthographic projection of the signal transmission line 70 on the base substrate; and / or, the orthographic projection of the blocking pattern 501 on the base substrate at least partially overlaps with the orthographic projection of the signal transmission line 70 on the base substrate.

[0068] Exemplarily, the signal transmission line 70 is coupled to the corresponding binding pin 60, for example: the multiple signal transmission lines 70 include multiple data lines (such as: DataW, DataR, DataG, DataB), multiple power lines (such as: VDD) and multiple sensing lines (such as: Sense); the data line is coupled to the corresponding data signal pin and can receive the data signal provided by the data signal pin; the power line is coupled to the corresponding power signal pin and can receive the power signal provided by the power signal pin; the sensing line is coupled to the corresponding sensing signal pin and can receive the sensing signal provided by the sensing signal pin.

[0069] Exemplarily, the signal transmission line 70 is provided in the same layer and material as the gate metal layer in the display panel, and the signal transmission line 70 can be formed into an integral structure with a conductive film layer included in its corresponding binding pin 60 .

[0070] Exemplarily, the signal transmission line 70 can extend from the binding area 13 to the first area 12 , the sealing area 11 and the display area in sequence, and couple with corresponding structures in the display area.

[0071] The above-mentioned setting that the orthographic projection of the spacer area Q1 on the base substrate at least partially overlaps with the orthographic projection of the signal transmission line 70 on the base substrate is beneficial to reducing the short circuit risk between the signal transmission line 70 and the blocking pattern 501.

[0072] The orthographic projection of the blocking pattern 501 on the base substrate is at least partially overlapped with the orthographic projection of the signal transmission line 70 on the base substrate, so that the blocking pattern 501 can be arranged as densely as possible along the first direction to achieve better water vapor blocking effect.

[0073] like Figure 1 and Figure 2 As shown, in some embodiments, the array substrate further includes:

[0074] a binding adhesive layer 80 , the binding adhesive layer 80 covering the binding pins 60 ;

[0075] In a group of barrier patterns 50 z farthest from the sealing frame area 11 , at least a portion of the first barrier portion 501 a in the barrier pattern 501 is located between the binding adhesive layer 80 and the functional film layer 40 .

[0076] Exemplarily, the bonding adhesive layer 80 includes ACF adhesive (anisotropic conductive adhesive), but is not limited thereto. The chip on film (COF) is bonded to the bonding pins 60 through the bonding adhesive layer 80 .

[0077] The above arrangement enables the barrier pattern 501 to effectively block water vapor from invading the functional film layer 40 from the side where the binding adhesive layer 80 is located, further enhancing the peripheral waterproof capability.

[0078] like Figure 1 and Figure 2 As shown, in some embodiments, in a group of barrier graphics 50z farthest from the sealing frame area 11, other parts of the first barrier portion 501a in the barrier graphics 501 are located between the protective adhesive layer 30 and the functional film layer 40, and the other parts are the parts of the first barrier portion 501a except the part located between the binding adhesive layer 80 and the functional film layer 40.

[0079] The above-mentioned setting method enables a group of barrier graphic groups 50z farthest from the sealing frame area 11 to be simultaneously located between the binding adhesive layer 80 and the functional film layer 40, and between the protective adhesive layer 30 and the functional film layer 40, thereby effectively blocking water vapor from invading the functional film layer 40 at the junction of the binding adhesive layer 80 and the protective adhesive layer 30, and further enhancing the peripheral waterproof capability.

[0080] like Figure 2 and Figure 4 As shown, in some embodiments, the barrier layer 50 includes at least two groups of barrier graphic groups 50z arranged along a second direction, where the second direction intersects with the first direction; among two adjacent groups of barrier graphic groups 50z, the spacer Q1 included in one barrier graphic group 50z is staggered along the first direction from the spacer Q1 included in the other barrier graphic group 50z.

[0081] This arrangement enables the at least two barrier pattern groups 50z to more effectively block water vapor from reaching the functional film layer 40, further enhancing the peripheral waterproofing capability. Furthermore, the at least two barrier pattern groups 50z form two barrier structures in the direction from the first region 12 toward the binding region 13. Therefore, even if water vapor invades the functional film layer 40 in the first region 12, the at least two barrier pattern groups 50z can further prevent the water vapor from spreading along the functional film layer 40 to the binding region 13, thereby preventing the water vapor from affecting the display function of the display product.

[0082] In addition, by arranging the spacer Q1 included in one barrier pattern group 50z in two adjacent barrier pattern groups 50z to be staggered along the first direction from the spacer Q1 included in the other barrier pattern group 50z, not only can the two adjacent barrier pattern groups 50z form an effective barrier structure, but it is also beneficial to further shorten the length of the orthographic projection of the barrier pattern 501 on the substrate along the first direction, thereby further reducing the risk of ESD generated by the barrier pattern 501.

[0083] like Figure 2 As shown, in some embodiments, except for a group of barrier pattern groups 50 z farthest from the sealing frame area 11 , other groups of barrier pattern groups 50 z are located between the protective adhesive layer 30 and the functional film layer 40 .

[0084] The above-mentioned setting method can more effectively prevent water vapor from invading the functional film layer 40 on the side where the protective adhesive layer 30 is located, thereby increasing the peripheral waterproof capability, thereby preventing water vapor from spreading along the functional film layer 40 to the binding area 13, and preventing water vapor from affecting the display function of the display product.

[0085] In some embodiments, the array substrate further includes a conductive layer, and the barrier layer 50 is provided in the same layer and with the same material as the conductive layer.

[0086] Exemplarily, the conductive layer is made of conductive metal material or indium tin oxide, but is not limited thereto.

[0087] Exemplarily, the density of the conductive layer is higher than the density of the functional film layer 40 .

[0088] The barrier layer 50 and the conductive layer are set in the same layer and material as above, so that the barrier layer 50 and the conductive layer can be formed simultaneously in the same composition process, thereby avoiding adding additional process flow to make the barrier layer 50, effectively simplifying the production process flow of the display panel and reducing the production cost of the display panel.

[0089] In some embodiments, the conductive layer includes an anode layer, and the barrier layer 50 is provided in the same layer and with the same material as the anode layer.

[0090] The barrier layer 50 is set to be in the same layer and material as the anode layer, so that the barrier layer 50 and the anode layer can be formed simultaneously in the same patterning process, thereby avoiding adding additional process flow to produce the barrier layer 50, effectively simplifying the production process flow of the display panel, and reducing the production cost of the display panel.

[0091] like Figures 1 to 3 As shown, in some embodiments, the array substrate includes a gate metal layer, a source / drain metal layer, and an anode layer stacked in sequence in a direction away from the base substrate;

[0092] The binding pins 60 in the array substrate include a first conductive film layer 601, a second conductive film layer 602 and a third conductive film layer 603 stacked in sequence in a direction away from the base substrate, the first conductive film layer 601 is arranged in the same layer and material as the gate metal layer, the second conductive film layer 602 is arranged in the same layer and material as the source and drain metal layer, the third conductive film layer 603 is arranged in the same layer and material as the barrier layer 50, and the third conductive film layer 603 is insulated from the barrier layer 50.

[0093] For example, taking the display panel including an organic light-emitting diode display panel as an example, the driving backplane of the display panel includes a light-shielding layer, a buffer layer BUF, an active layer, a gate insulating layer GI, a gate layer GT, an interlayer insulating layer ILD, a source-drain metal layer SD, a passivation layer PVX, a color filter layer, an organic planarization layer, an anode layer and a pixel defining layer, which are stacked in sequence in a direction away from the base substrate, but are not limited to this.

[0094] When the driving backplane includes the above-mentioned film layer, the production of the driving backplane includes the following process sequence: light-shielding layer mask, ACT mask, GT mask, CNT mask, ILD mask, SD mask, PVX deposition, color filter layer production, organic planar layer deposition, organic planar layer mask, VIA mask, anode layer mask, and pixel definition layer production.

[0095] Specific as Figure 3 As shown, the second conductive film layer 602 is coupled to the first conductive film layer 601 through ILD vias, and the third conductive film layer 603 is coupled to the second conductive film layer 602 through VIA vias. The organic planarization layer and pixel definition layer in the entire bonding area 13 are removed.

[0096] The above-mentioned first conductive film layer 601 is set to the same layer and material as the gate metal layer, so that the first conductive film layer 601 and the gate metal layer can be formed simultaneously in the same composition process; the second conductive film layer 602 is set to the same layer and material as the source / drain metal layer, so that the second conductive film layer 602 and the source / drain metal layer can be formed simultaneously in the same composition process; the third conductive film layer 603 is set to the same layer and material as the barrier layer 50, so that the third conductive film layer 603 and the barrier layer 50 can be formed simultaneously in the same composition process. The above-mentioned setting method enables the binding pin 60 to be formed simultaneously during the production process of other structures in the display panel, avoiding the addition of an additional composition process for the production of the binding pin 60, thereby effectively simplifying the production process flow of the display panel and reducing the production cost of the display panel.

[0097] The above arrangement enables the binding pins 60 to be formed into a structure including three conductive film layers, thereby ensuring the conductive performance of the binding pins 60 and the yield rate of the binding pins 60 .

[0098] like Figure 1 and Figure 2 As shown, in some embodiments, the array substrate further includes:

[0099] An organic protective layer 90, at least part of which is located between the protective glue layer 30 and the functional film layer 40, and the orthographic projection of the organic protective layer 90 on the base substrate is located between the orthographic projection of the barrier layer 50 on the base substrate and the orthographic projection of the sealing glue layer 110 on the base substrate.

[0100] Exemplarily, the organic protective layer 90 is made of an organic insulating layer material, and the organic protective layer 90 is set in the same layer and material as the organic flat layer. This setting method enables the organic protective layer 90 to be formed simultaneously with the organic flat layer in the same composition process, effectively simplifying the production process and production cost of the display panel.

[0101] The above-mentioned arrangement of at least a portion of the organic protective layer 90 being located between the protective adhesive layer 30 and the functional film layer 40 enables the organic protective layer 90 to block water vapor from invading the functional film layer 40 located therebelow, thereby preventing water vapor from spreading along the functional film layer 40 to the binding area 13, and preventing water vapor from affecting the display function of the display product.

[0102] The above-mentioned orthographic projection of the organic protective layer 90 on the base substrate is located between the orthographic projection of the barrier layer 50 on the base substrate and the orthographic projection of the frame-sealing adhesive layer 110 on the base substrate. This not only enables the organic protective layer 90 and the barrier layer 50 to protect the functional film layer 40 below the protective adhesive layer 30 from water vapor intrusion, but also ensures that the barrier layer 50 has a certain distance from the frame-sealing area 11, thereby avoiding a short circuit between the barrier layer 50 and the conductive structure of the frame-sealing area 11.

[0103] An embodiment of the present invention further provides a display device, comprising the display panel provided by the above embodiment.

[0104] Exemplarily, the display device includes, but is not limited to, a liquid crystal display device, an organic light-emitting diode display device, an active-matrix organic light-emitting diode display device, etc. Exemplarily, the display device includes a medium or large-sized display device, and the display device may have a high resolution, but is not limited to this.

[0105] It should be noted that the display device can be any product or component with a display function, such as a television, a monitor, a digital photo frame, a mobile phone, a tablet computer, etc., wherein the display device also includes a flexible circuit board, a printed circuit board and a backplane.

[0106] In the display panel provided in the above embodiment, a barrier layer 50 with a higher density is disposed between the protective adhesive layer 30 and the functional film layer 40. This barrier layer 50 more effectively blocks water vapor from entering the functional film layer 40, enhancing the peripheral waterproofing capability.
