Description

Technical Field

[0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background Art

[0002] Currently, display panels are widely used in various electronic devices. Before the display panel is bonded to the driver chip (Integrated Circuit, IC), a visual test (VT) is generally performed to ensure the quality of the display panel.

[0003] In the existing display panel structure, the visual effect test unit includes an electrostatic release unit, which is arranged below the cutting line of the color film substrate. In this way, when the color film substrate is cut, a large amount of static electricity will be generated by the friction between the cutting wheel and the glass. The released static electricity will damage the electrostatic release unit below the cutting line of the color film substrate and even cause the performance of the electrostatic release unit to fail, thereby affecting the subsequent VT visual effect inspection. Summary of the Invention

[0004] In view of this, the present invention provides a display panel and a display device, which aim to reduce the impact of static electricity generated by cutting a color filter substrate on an electrostatic release unit, thereby ensuring the electrostatic release effect of the display panel, and further facilitating improving the success rate of visual testing of the display panel.

[0005] The technical solutions of the present invention are as follows:

[0006] In one aspect, the present invention provides a display panel, comprising a display area and a non-display area surrounding the display area; the non-display area comprises a first frame area, and the first frame area is located on one side of the display area along a first direction;

[0007] The display panel includes a color filter substrate and an array substrate that are arranged opposite to each other;

[0008] In the first border area, the edge of the color filter substrate includes a first edge;

[0009] The array substrate includes a plurality of visual effect detection units, and the visual effect detection units include electrostatic release units;

[0010] Along the thickness direction of the display panel, the electrostatic discharge unit does not overlap with the first edge;

[0011] Wherein, the first direction is parallel to the plane where the display panel is located.

[0012] In a second aspect, based on the same inventive concept, the present invention further provides a display device comprising any of the above-mentioned display panels.

[0013] Compared with related technologies, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0014] In the display panel structure of the present invention, the electrostatic release unit does not overlap with the first edge of the color film substrate along the thickness direction of the display panel. Therefore, the electrostatic release unit can avoid the cutting position of the color film substrate. In this way, when the color film substrate is cut, since the electrostatic release unit deviates from the cutting line position, the damage to the electrostatic release unit caused by static electricity generated by the cutting will be reduced, thereby helping to improve the reliability of the electrostatic release unit and facilitating subsequent visual effects testing.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the technical effects described above at the same time.

[0030] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0033] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0034] It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the present invention. Therefore, the present invention is intended to cover modifications and variations of the present invention that fall within the scope of the corresponding claims (technical solutions claimed for protection) and their equivalents. It should be noted that the embodiments provided in the embodiments of the present invention may be combined with each other unless there is any contradiction.

[0035] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0036] The present invention provides a display panel, comprising a display area and a non-display area surrounding the display area; the non-display area comprises a first frame area, the first frame area being located on one side of the display area along a first direction; the display panel comprises a color filter substrate and an array substrate arranged opposite to each other; in the first frame area, the edge of the color filter substrate comprises a first edge; the array substrate comprises a plurality of visual effect detection units, the visual effect detection units comprising an electrostatic release unit; along the thickness direction of the display panel, the electrostatic release unit does not overlap with the first edge; wherein the first direction is parallel to the plane where the display panel is located. In the display panel structure of the present invention, along the thickness direction of the display panel, the electrostatic release unit does not overlap with the first edge of the color filter substrate, thereby allowing the electrostatic release unit to avoid the cutting position of the color filter substrate; thus, when the color filter substrate is cut, since the electrostatic release unit deviates from the cutting line position, the damage to the electrostatic release unit caused by the static electricity generated by the cutting will be reduced, thereby helping to improve the reliability of the electrostatic release unit and facilitating subsequent visual effect testing.

[0037] The above is the core concept of the present invention. The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the embodiments of the present invention.

[0038] Figure 1 FIG. 1 is a schematic structural diagram of a display panel provided by an embodiment of the present invention. Figure 2 for Figure 1 The side view of the display panel structure is shown. Figure 1 and Figure 2 The display panel 100 of the present invention includes a display area AA and a non-display area NA surrounding the display area AA; the non-display area NA includes a first frame area NA1, and the first frame area NA1 is located on one side of the display area AA along the first direction Y; the display panel 100 includes a color filter substrate B1 and an array substrate B2 that are oppositely arranged; in the first frame area NA1, the edge of the color filter substrate B1 includes a first edge B11; the array substrate B2 includes a plurality of visual effect detection units, and the visual effect detection unit includes an electrostatic release unit 10; along the thickness direction of the display panel 100, the electrostatic release unit 10 has no overlap with the first edge B11; wherein, the first direction Y is parallel to the plane where the display panel 100 is located.

[0039] Specifically, the production of display panels generally includes four process sections, namely, the array substrate production process, the color film substrate production process, the boxing process and the cutting process. When the array substrate is produced, a large array substrate may include multiple array substrate units, and a large color film substrate may include a corresponding number of color film units. In the boxing process, the corresponding array substrate units and color film units are oriented and then pasted into a box; in the cutting process, the box is first cut to form multiple display panels, and then the color film substrate in a single display panel is cut to expose the array substrate in the first frame area.

[0040] Some components at NA1, such as the visual effect detection unit.

[0041] Please continue to refer to Figure 1 and Figure 2 In the first frame area NA1 , the color filter substrate B1 forms the first edge B11 after being cut. Therefore, the first edge B11 of the color filter substrate B1 is located at the cutting line of the color filter substrate B1 .

[0042] Specifically, when the color filter substrate B1 is cut, the static electricity generated by the cutting is concentrated at the cutting seam. In the present invention, the static electricity release unit 10 is arranged so that it does not overlap with the first edge B11 along the thickness direction of the display panel 100. This allows the static electricity release unit 10 to be offset from the cutting seam in a direction parallel to the plane of the display panel. Therefore, when the color filter substrate B1 is cut, the static electricity generated by the cutting does not directly act on the static electricity release unit 10. Generally speaking, the impact force of static electricity is proportional to the magnitude of the static electricity and inversely proportional to the distance from which the static electricity acts. Therefore, the farther away from the static electricity, the less impactful the static electricity. Therefore, the present invention adopts a setting method in which the electrostatic release unit 10 and the first edge B11 are not overlapped, so that the electrostatic release unit 10 deviates from the cutting line position, and the cutting static electricity does not directly act on the electrostatic release unit 10; and because the electrostatic release unit 10 is a certain distance away from the cutting seam, the damaging force generated by the cutting static electricity on the electrostatic release unit 10 is reduced compared with the method in which the cutting static electricity directly acts on the electrostatic release unit 10; therefore, the display panel of the present invention adopts a setting method in which the electrostatic release unit 10 and the first edge B11 are not overlapped, which helps to improve the reliability of the electrostatic release unit 10 and facilitates subsequent visual effects testing.

[0043] It should be noted that Figure 1 The technical solution of not overlapping the electrostatic discharge unit 10 and the first edge B11, thereby reducing the damage to the electrostatic discharge unit 10 caused by cutting static electricity, is described by taking the rectangular display panel 100 as an example. Figure 1The structure shown does not limit the actual shape and structure of the display panel 100. In some other embodiments of the present invention, the shape of the display panel 100 can also be embodied in other shapes, and the position of the first border area NA1 can also be at other positions. In addition, the present invention is intended to illustrate the problem that the electrostatic discharge unit in the visual effect test unit is affected by the static electricity of the color filter substrate cutting. It has little relevance to other components of the display panel. Therefore, some structures of the display panel are not shown in the figure. Figure 1 Shown in.

[0044] Figure 3 The figure shows a top view of the electrostatic discharge unit provided by the embodiment of the present invention. Figure 1 and Figure 3 In some optional embodiments of the present invention, the electrostatic discharge unit 10 includes a first side A1 and a second side A2, the extension direction of the first side A1 is parallel to the first direction Y, and the extension direction of the second side A2 is parallel to the second direction X; along the first direction Y, the length of the first side A1 is a1, and along the second direction X, the length of the second side A2 is a2, wherein a1<a2; wherein the first direction Y intersects the second direction X, and the second direction X is parallel to the plane where the display panel 100 is located.

[0045] Figure 4 The figure shows a schematic diagram of the structure of a display panel provided by the related art. Please refer to Figure 4 Specifically, narrow frame design has become a development trend, and the visual effect detection unit is an indispensable component in the first frame area NA1; in order to meet the requirements of the narrow frame, in the relevant technology, the electrostatic release unit 10 in the visual effect detection unit will be placed below the cutting line of the color film substrate (the first edge B11); in this way, when the color film substrate B1 is being cut, the cutting static electricity directly acts on the electrostatic release unit 10. When the cutting static electricity is large, the electrostatic release unit 10 will be damaged, affecting the subsequent VT visual effect inspection.

[0046] In addition, please Figure 1 and Figure 4 For comparison, Figure 1 and Figure 4 In the display panel structure shown, the shapes of the electrostatic discharge units 10 are similar to Figure 3 The rectangle shown is different in that Figure 4 In the structure shown, the long side (second side A2) of the electrostatic discharge unit 10 extends along the first direction Y, and the short side (first side A1) of the electrostatic discharge unit 10 extends along the second direction X; Figure 1 In the structure shown, the long side (second side A2) of the electrostatic discharge unit 10 extends along the second direction X, and the short side (first side A1) of the electrostatic discharge unit 10 extends along the first direction Y; Figure 1The distance occupied by the electrostatic discharge unit 10 in the first direction Y is relative to Figure 4 The distance occupied by the electrostatic discharge unit 10 in the first direction Y is small.

[0047] In summary, in some optional embodiments of the present invention, the electrostatic release unit 10 is arranged horizontally (i.e., the extension direction of the long side of the electrostatic release unit 10 is parallel to the second direction X), and the setting distance required for the electrostatic release unit 10 in the first direction Y will be reduced; that is, in the first direction Y, the setting distance required for the electrostatic release unit 10 in the first border area NA1 is reduced, thereby helping to reduce the width of the first border area NA1 in the Y direction and achieve a narrow border of the first border area NA1 in the Y direction; at the same time, since the setting distance required for the horizontally placed electrostatic release unit 10 in the first direction Y is reduced, when the width of the first border area NA1 along the Y direction is limited, the horizontally placed electrostatic release unit 10 is easier to avoid the first edge B11 (color film substrate cutting line) than the longitudinally placed electrostatic release unit 10. In this way, when cutting the color film substrate B1, since the electrostatic release unit 10 has a certain distance from the cutting position along the first direction Y, and the greater the distance, the smaller the influence of the cutting static electricity on the electrostatic release unit 10, and the smaller the damage. Therefore, the electrostatic discharge unit 10 of the present invention is arranged horizontally, which can not only avoid the cutting position and reduce the impact of cutting static electricity on the electrostatic discharge unit 10, but also help to achieve a narrow frame of the display panel.

[0048] In addition, please continue to refer to Figure 4 Generally, along the first direction Y, the visual effect detection unit and its surroundings contain many wires and components. To facilitate space allocation within the panel, these wires and components are arranged in a regular pattern, so the layout of the visual effect detection unit is relatively fixed. Therefore, the placement space of the electrostatic discharge unit 10 in the first border area NA1 is also relatively limited.

[0049] The present invention arranges the electrostatic discharge unit horizontally, i.e., the long side (second side A2) of the electrostatic discharge unit 10 extends along the second direction X, and the short side (first side A1) of the electrostatic discharge unit 10 extends along the first direction Y. Since the required installation distance of the horizontally arranged electrostatic discharge unit 10 in the first direction Y is reduced, and the existing placement space of the discharge unit 10 can meet the requirements of the horizontal arrangement of the electrostatic discharge unit 10, the present invention can avoid the color filter substrate cutting position without changing the existing placement space of the electrostatic discharge unit 10. Thus, the present invention only changes the placement direction of the electrostatic discharge unit 10 and can avoid the color filter substrate cutting position without increasing the width of the first border area NA1, thereby reducing or even eliminating the impact of cutting static electricity on the electrostatic discharge unit 10, achieving a very significant effect.

[0050] Please continue to refer to Figure 4 and Figure 3 In the case where the long side (second side A2) of the electrostatic discharge unit 10 extends along the first direction Y and the short side (first side A1) of the electrostatic discharge unit 10 extends along the second direction X, in order to ensure that the electrostatic discharge unit 10 does not overlap with the first edge B11, Figure 4 On the basis of the structure shown, by widening the width of the first frame area NA1 in the first direction Y, the electrostatic release unit 10 is vertically placed on the side of the first edge B11 close to the display area AA, or the electrostatic release unit 10 is vertically placed on the side of the first edge B11 close to the side away from the display area AA; in this way, the electrostatic release unit 10 can also be deviated from the cutting line position. When the color film substrate B1 is cut, since the electrostatic release unit 10 is at a certain distance from the cutting position, based on similar reasons to the above, the damage to the electrostatic release unit 10 caused by the static electricity generated by the cutting will be reduced. , therefore, it helps to improve the reliability of the electrostatic discharge unit 10 and facilitates the subsequent visual effect test; but there is no doubt that if the electrostatic discharge unit 10 is placed vertically on the side of the first edge B11 close to the display area AA, then the distance between the first edge B11 and the display area AA in the first direction Y will be relatively large; if the electrostatic discharge unit 10 is placed vertically on the side of the first edge B11 away from the display area AA, then the distance between the first edge B11 and the array substrate B2 in the first direction Y will be relatively large; therefore, this method is suitable for display panels with a larger space in the first border area NA1 in the first direction Y.

[0051] Figure 5 The figure shows a schematic diagram of the structure of the display panel visual effect detection unit provided by an embodiment of the present invention; please refer to Figure 5In some optional embodiments of the present invention, the electrostatic release unit 10 includes a positive voltage release unit 101 and a negative voltage release unit 102. Along the first direction Y, the positive voltage release unit 101 and the negative voltage release unit 102 are located on opposite sides of the first edge B11.

[0052] Specifically, please combine Figure 1 and Figure 5 In some embodiments of the present invention, the positive voltage release unit 101 and the negative voltage release unit 102 in the display panel 100 are arranged on opposite sides of the first edge B11; this structure, relative to the structure in which the positive voltage release unit 101 and the negative voltage release unit 102 are both located above the first edge B11 or both located below the first edge B11, can, to a certain extent, avoid the phenomenon that the space above or below the first edge B11 is tight and it is difficult to accommodate the positive voltage release unit 101 and the negative voltage release unit 102 at the same time; and to a certain extent, by placing the positive voltage release unit 101 and the negative voltage release unit 102 on opposite sides of the first edge B11 along the first direction Y, it can avoid the first border area NA1 from widening in the first direction Y, which helps to achieve a narrow border effect of the display panel 100.

[0053] In addition, the positive voltage release unit 101 and the negative voltage release unit 102 are placed on opposite sides of the first edge B11 along the first direction Y. In this way, the distances of the positive voltage release unit 101 and the negative voltage release unit 102 from the first edge B11 in the first direction Y can be equal. Then, the influence of the cutting static electricity on the positive voltage release unit 101 and the negative voltage release unit 102 is almost the same, avoiding the situation where one of the positive voltage release unit 101 and the negative voltage release unit 102 is too close to the first edge B11 and the other is too far from the first edge B11. In this way, the cutting static electricity is more likely to damage the positive voltage release unit 101 and the negative voltage release unit 102 that are closer. Please continue to refer to Figure 5 In some optional embodiments of the present invention, the visual effect detection unit further includes a detection signal line 11, a detection electrode 12, a positive voltage lead-out line 14 and a negative voltage lead-out line 13; the detection signal line 11 is connected to the detection electrode 12; the input ends of the positive voltage release unit 101 and the negative voltage release unit 102 are both connected to the detection signal line 11, the output end of the positive voltage release unit 101 is connected to the positive voltage lead-out line 14, and the output end of the negative voltage release unit 102 is connected to the negative voltage lead-out line 13.

[0054] Specifically, as mentioned above, when the visual effects test unit performs a visual effects test, it inputs a signal through the detection electrode 12, causing the display panel 100 to display a solid color image or a checkerboard image for testing. The detection signal line 11 is used to transmit the signal input by the detection electrode 12, such as a gate drive signal, a source drive signal, a light-emitting drive signal, etc. When the static electricity at the detection signal line 11 or the positive voltage signal or negative voltage signal transmitted by the detection signal line 11 is too large, it is easy to burn out the detection signal line 11. Therefore, in order to ensure the normal use of the detection signal line 11, the detection signal line 11 is connected to the static discharge unit 10 to release static electricity and excessive positive or negative voltage. In the present invention, the input ends of the positive voltage release unit 101 and the negative voltage release unit 102 are both connected to the detection signal line 11, the output end of the positive voltage release unit 101 is connected to the positive voltage lead-out line 14, and the output end of the negative voltage release unit 102 is connected to the negative voltage lead-out line 13; in this way, the static electricity and excessive positive or negative voltage on the detection signal line 11 can be released through the corresponding positive voltage lead-out line 14 and the negative voltage lead-out line 13, thereby ensuring the normal use of the detection signal line 11.

[0055] Please continue to refer to Figure 5 In some optional embodiments of the present invention, along the first direction Y, the positive voltage lead-out line 14 and the negative voltage lead-out line 13 are located on both sides of the first edge B11; the positive voltage release unit 101 is located between the first edge B11 and the positive voltage lead-out line 14; and the negative voltage release unit 102 is located between the first edge B11 and the negative voltage lead-out line 13.

[0056] Specifically, please combine Figure 1 and Figure 5 As mentioned above, the static electricity at the detection signal line 11 includes positive static electricity and negative static electricity, and the signal transmitted by the detection signal line 11 includes positive voltage and negative voltage. For the positive voltage release unit 101 and the negative voltage release unit 102, the positive voltage release unit 101 and the negative voltage release unit 102 are both electronic devices. Whether it is positive static electricity, positive voltage, negative static electricity or negative voltage, if it is too large, it will cause damage to surrounding devices; for example, if the positive static electricity or positive voltage is too large and exceeds the output capacity of the positive voltage release unit 101, then it is possible to burn the positive voltage release unit 101. If the distance between the negative voltage release unit 102 and the positive voltage release unit 101 is too close, at this time, after burning the positive voltage release unit 101, the static electricity may continue to break through the air and damage the negative voltage release unit 102.

[0057] Positive static electricity and excessive positive voltage need to be derived from the positive voltage release unit 101, and negative static electricity and excessive negative voltage need to be derived from the negative voltage release unit 102; therefore, in order to avoid the influence of excessive positive voltage and positive static electricity on the negative voltage release unit 102 or the influence of negative static electricity and excessive negative voltage on the positive voltage release unit 101, and at the same time to facilitate the release of positive static electricity, excessive positive voltage, negative static electricity and excessive negative voltage as soon as possible, the positive voltage release unit 101 of the present invention is located between the first edge B11 and the positive voltage lead-out line 14; the negative voltage release unit 102 is located between the first edge B11 and the negative voltage lead-out line 13, which can not only enable the static electricity to be released relatively quickly, but also enable the positive voltage release unit 101 and the negative voltage release unit 102 to be at a greater distance to avoid damage to both at the same time.

[0058] Please continue to refer to Figure 5 Along the second direction X, the positive voltage release unit 101 and the negative voltage release unit 102 are located on opposite sides of the detection signal line 11 .

[0059] Specifically, please combine Figure 1 and Figure 5 As mentioned above, the static electricity at the detection signal line 11 includes positive static electricity and negative static electricity, and the signal transmitted by the detection signal line 11 includes positive voltage and negative voltage. In order to avoid the influence of excessive positive voltage and positive static electricity on the negative voltage release unit 102 or the influence of negative static electricity and excessive negative voltage on the positive voltage release unit 101, and at the same time to facilitate the release of positive static electricity, excessive positive voltage, negative static electricity and excessive negative voltage as soon as possible, the positive voltage release unit 101 of the present invention is located between the first edge B11 and the positive voltage lead-out line 14; the negative voltage release unit 102 is located between the first edge B11 and the negative voltage On this basis, along the second direction X, the positive voltage release unit 101 and the negative voltage release unit 102 are arranged on opposite sides of the detection signal line 11. In this way, the positive voltage release unit 101 and the negative voltage release unit 102 are located at the diagonal position of the plane determined by the second direction X and the first direction Y. In this way, the distance between the positive voltage release unit 101 and the negative voltage release unit 102 can be further increased. Based on similar reasons to the above, the increase in distance can further prevent excessive voltage or static electricity from causing damage to the positive voltage release unit 101 and the negative voltage release unit 102 at the same time.

[0060] Figure 6 The figure shows a simplified structural diagram of the display panel visual effect detection unit provided by an embodiment of the present invention; Figure 7FIG2 is a simplified structural diagram of a display panel visual effect detection unit provided by an embodiment of the present invention; Figure 6 and Figure 7 In some optional embodiments of the present invention, the forward voltage release unit 101 includes a first sub-forward voltage release unit 1011 and a second sub-forward voltage release unit 1012, and the first sub-forward voltage release unit 1011 and the second sub-forward voltage release unit 1012 are located on opposite sides of the detection signal line 11; the negative voltage release unit 102 includes a first sub-negative voltage release unit 1021 and a second sub-negative voltage release unit 1022, and the first sub-negative voltage release unit 1021 and the second sub-negative voltage release unit 1022 are located on opposite sides of the detection signal line 11.

[0061] In some specific embodiments of the present invention, in order to meet or reduce the size of the first border area NA1 in the first direction Y or the second direction X, the positive voltage release unit 101 is split into a first sub-positive voltage release unit 1011 and a second sub-positive voltage release unit 1012, and the negative voltage release unit 102 is split into a first sub-negative voltage release unit 1021 and a second sub-negative voltage release unit 1022. In this way, the purpose of meeting or reducing the size of the first border area NA1 in the first direction Y or the second direction X can be achieved by making full use of the space. In addition, the positive voltage release unit 101 includes a first sub-positive voltage release unit 1011 and a second sub-positive voltage release unit 1012, so that the positive voltage can be simultaneously derived from the first sub-positive voltage release unit 1011 and the second sub-positive voltage release unit 1012, so that the release of excessive positive voltage can be accelerated, which is beneficial to avoid the detection signal line 11 being burned by the large positive voltage; similarly, the negative voltage release unit 102 includes a first sub-negative voltage release unit 1021 and a second sub-negative voltage release unit 1022, so that the large negative voltage can be simultaneously derived from the first sub-negative voltage release unit 1021 and the second sub-negative voltage release unit 1022, so that the release of excessive negative voltage can be accelerated, which is beneficial to avoid the detection signal line 11 being burned by the large negative voltage.

[0062] For details, please continue to refer to Figure 6 In some specific embodiments of the present invention, the first sub-positive voltage release unit 1011, the second sub-positive voltage release unit 1012, the first sub-negative voltage release unit 1021 and the second sub-negative voltage release unit 1022 each include at least two rows of transistor devices arranged along the second direction.

[0063] Specifically, the electrostatic discharge unit 10 is formed by connecting a plurality of transistor devices T in parallel. The plurality of transistor devices T can be arranged in one row, or in two or more rows. Figure 8Shown is an arrangement diagram of the electrostatic discharge unit provided by an embodiment of the present invention; Figure 8 In the electrostatic discharge unit 10, multiple transistor devices T are arranged in two rows. Figure 6 and Figure 8 When the positive static electricity, negative static electricity, positive voltage, and negative voltage are large or need to be released as quickly as possible, the static electricity can be conducted away as quickly as possible by increasing the number of transistor devices T in the electrostatic release unit 10. However, if the number of transistor devices T arranged in the electrostatic release unit 10 is increased, the length of the electrostatic release unit 10 in the second direction X or the first direction Y will inevitably increase, which is not conducive to the realization of a narrow border of the first border area NA1. Based on this, in order not to increase or reduce the width of the first border area NA1 in the second direction X, the positive voltage release unit 101 can be divided into a first sub-positive voltage release unit 1011 and a second sub-positive voltage release unit 1012, and the first sub-positive voltage release unit 1011 and the second sub-positive voltage release unit 1012 are in a parallel relationship; the negative voltage release unit 102 is divided into a first sub-negative voltage release unit 1021 and a second sub-negative voltage release unit 1022, and the first sub-negative voltage release unit 1021 and the second sub-negative voltage release unit 1022 are in a parallel relationship. The first and second sub-positive voltage release units 1011, 1012, 1021, 1022 are connected in parallel. On this basis, the first sub-positive voltage release unit 1011, the second sub-positive voltage release unit 1012, the first sub-negative voltage release unit 1021, and the second sub-negative voltage release unit 1022 each include at least two rows of triode devices arranged along the second direction X. In this way, the requirements for releasing positive polarity static electricity, negative polarity static electricity, positive large voltage, and negative large voltage as quickly as possible can be met, and the width of the first border area NA1 in the second direction X can be maintained without increasing or even reduced. In terms of layout, the first sub-positive voltage release unit 1011 and the second sub-positive voltage release unit 1012 are arranged on opposite sides of the detection signal line 11 along the second direction X, and are located on opposite sides of the first edge B11 along the first direction Y. The first sub-negative voltage release unit 1021 and the second sub-negative voltage release unit 1022 are arranged on opposite sides of the detection signal line 11 along the second direction X, and are located on opposite sides of the first edge B11 along the first direction Y. In this way, space can be fully utilized, thereby achieving a space-saving effect.

[0064] For details, please continue to refer to Figure 7 In some specific embodiments of the present invention, the first sub-positive voltage release unit 1011, the second sub-positive voltage release unit 1012, the first sub-negative voltage release unit 1021 and the second sub-negative voltage release unit 1022 each include a row of transistor devices arranged along the second direction X.

[0065] Figure 9 FIG. 1 shows another arrangement diagram of the electrostatic discharge unit provided in an embodiment of the present invention; FIG. Figure 9 In the embodiment, the multiple transistor devices T in the electrostatic discharge unit 10 are arranged in a single row.

[0066] Please combine Figure 7 and Figure 9 In some embodiments of the present invention, it is desired that the size of the first border area NA1 in the first direction Y is as small as possible; as mentioned above, the electrostatic release unit 10 is formed by connecting multiple transistor devices in parallel, and the multiple transistor devices T can be arranged in a row or in multiple rows; therefore, the electrostatic release unit 10 can be split in the first direction Y or in the second direction X; based on this, the electrostatic release unit 10 is split in the first direction Y to form a first sub-positive voltage release unit 1011, a second sub-positive voltage release unit 1012, a first sub-negative voltage release unit 1021, and a second sub-negative voltage release unit 1022, and the first sub-positive voltage release unit 1011, the second sub-positive voltage release unit 1012, the first sub-negative voltage release unit 1021, and the second sub-negative voltage release unit 1022 all include a row of transistor devices arranged along the second direction X. In this way, the space of the first border area NA1 along the first direction Y can be saved.

[0067] Figure 10 The figure shows a schematic diagram of the structure of the display panel visual effect detection unit provided by an embodiment of the present invention; please refer to Figure 10 In some specific embodiments of the present invention, the multiple visual effect detection units include adjacent first detection signal lines 111 and second detection signal lines 112 arranged along the second direction X; the projections of the electrostatic release unit 10 connected to the first detection signal line 111 and the electrostatic release unit 10 connected to the second detection signal line 112 along the first direction Y overlap.

[0068] Please combine Figure 5 and Figure 10 ,like Figure 5As shown, in some embodiments of the present invention, the detection signal line 11 is connected to a positive voltage release unit 101 and a negative voltage release unit 102. In order to avoid damage to the negative voltage release unit 102 by positive polarity static electricity and damage to the positive voltage release unit 101 by negative polarity static electricity, the positive voltage release unit 101 is located between the first edge B11 and the positive voltage lead-out line 14; the negative voltage release unit 102 is located between the first edge B11 and the negative voltage lead-out line 13, and the positive voltage release unit 101 and the negative voltage release unit 102 are arranged on opposite sides of the detection signal line 11. In this way, the positive voltage release unit 101 is only located on one side of the detection signal 11 along the second direction X, then the position of the detection signal 11 on the other side along the second direction X opposite to the positive voltage release unit 101 is vacant, and the position of the detection signal 11 on the other side along the second direction X opposite to the negative voltage release unit 101 is also vacant.

[0069] In some embodiments of the present invention, due to the limitation of space position, it is necessary to arrange the detection electrodes 12 in double rows, and the arrangement space of the electrostatic discharge unit 10 in the second direction X is relatively tight. In order to make full use of the space, please combine Figure 5 and Figure 10 The present invention sets an electrostatic discharge unit 10 of another adjacent detection signal line 112 at the above-mentioned vacant position, so as to achieve the purpose of saving space as much as possible.

[0070] Figure 11 The figure shows another structural schematic diagram of the location of a display panel visual effect detection unit provided by an embodiment of the present invention; in some specific embodiments of the present invention, the array substrate B2 includes an electrostatic conduction line L1, which extends along the second direction X, and along the thickness direction of the display panel 100, the electrostatic conduction line L1 overlaps with the projection of the first edge B11.

[0071] Specifically, please combine Figure 1 and Figure 11 When cutting the color filter substrate B1, a large amount of cutting static electricity will be generated. In order to enhance the static electricity protection effect, an electrostatic conduction line L1 can be set below the first edge B11. The electrostatic conduction line L1 is in direct contact with the color filter substrate B1. When the pulley cuts the color filter substrate B1 and generates static electricity, when the static electricity accumulates to a certain amount, it will break through the air and be directly introduced into the electrostatic conduction line L1 at the cutting seam. In this way, the cutting static electricity can be discharged as quickly as possible through the electrostatic conduction line L1 to avoid affecting surrounding devices.

[0072] Please continue to refer to Figure 11 In some specific embodiments of the present invention, the array substrate B2 further includes a ground line L2, and the electrostatic conduction line L1 is electrically connected to the ground line L2.

[0073] Specifically, the array substrates B2 all include a grounding line L2. The present invention electrically connects the electrostatic conduction line L1 to the existing grounding line L2 of the array substrate B2 itself. In this way, the static electricity passing through the electrostatic conduction line L1 can be discharged with the help of the grounding line L2. This method can save process and facilitate static electricity discharge.

[0074] Please continue to refer to Figure 11 In some specific embodiments of the present invention, the array substrate B2 further includes an active layer, and the electrostatic conduction line L2 is disposed in the active layer.

[0075] Specifically, the active layer is mainly used to form the channel region of the triode device. The layout area is not large and has sufficient idle space. The present invention arranges the electrostatic conduction line L2 in the active layer. In this way, the idle space of the active layer can be fully utilized, while avoiding the inconvenience caused by setting the electrostatic conduction line L2 through a new film layer or squeezing the wiring space of other film layers to set the electrostatic conduction line L2.

[0076] Based on the same inventive concept, the present invention also provides a display device, please refer to Figure 12 , Figure 12 FIG2 is a schematic structural diagram of a display device provided by an embodiment of the present invention. The display device 200 provided by this embodiment includes the display panel 100 provided by any of the above embodiments.

[0077] It is understood that the display device 200 provided in the embodiment of the present invention can be a computer, mobile phone, tablet computer, or other display device with a display function, and the present invention does not specifically limit this. The display device provided in the embodiment of the present invention has the beneficial effects of the display panel provided in the embodiment of the present invention. For details, please refer to the detailed description of the display panel in the above embodiments, and this embodiment will not be repeated here.

[0078] In summary, the display panel and display device provided by the present invention achieve at least the following beneficial effects:

[0079] In the present invention, the electrostatic release unit 10 is arranged in a non-overlapping manner with the first edge B11 along the thickness direction of the display panel 100, so that the electrostatic release unit 10 deviates from the cutting line position in the direction parallel to the display panel, that is, the electrostatic release unit 10 is at a certain distance from the cutting position; in this way, when the color film substrate B1 is cut, since the electrostatic release unit 10 is at a certain distance from the cutting position, the damage to the electrostatic release unit 10 caused by the static electricity generated by the cutting will be reduced, thereby helping to improve the reliability of the electrostatic release unit 10 and facilitating subsequent visual effects testing.
